PART I

 

Item 1. Business

 

Overview

 

We are a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain. Our lead product candidate is ZalvisoTM, formerly known as ARX-01. Zalviso is intended for the management of moderate-to-severe acute pain in hospitalized adult patients. Zalviso consists of sufentanil sublingual tablets delivered by the Zalviso System, a needle-free, handheld, patient-administered, pain management system (together, “Zalviso”).

 

On July 25, 2014, the U.S. Food and Drug Administration, or FDA, issued a Complete Response Letter, or CRL, for our New Drug Application, or NDA, for Zalviso. The CRL contains requests for additional information on the Zalviso System to ensure proper use of the device. The requests include submission of data demonstrating a reduction in the incidence of optical system errors, changes to the Instructions for Use for the device to address inadvertent dosing, among other items, and submission of additional data to support the shelf life of the product. In the third quarter of 2014, we held a Type A meeting with the FDA to discuss the Zalviso CRL received in July. During the meeting we discussed the resubmission of the Zalviso NDA and the steps necessary for the resubmission. In advance of resubmitting our Zalviso NDA, we agreed with the FDA to submit protocols for the bench testing and Human Factors, or HF, studies for their review and comment. In addition, the FDA requested in the minutes of the meeting that we provide a risk assessment that analyzes the risks associated with inadvertent dosing and the rationale that bench testing and HF studies are sufficient to address the specific items included in the CRL. We submitted the protocols and this rationale in the fourth quarter of 2014. In January 2015, we received feedback from the FDA on the protocol and the planned analysis of the results of the bench test. No modifications to the conduct of the bench test were necessary; however, in response to the FDA’s request, we refined the planned analysis of the bench test results. In February 2015, we received feedback from the FDA on the HF protocols. In this feedback, the FDA confirmed that the HF studies as proposed were acceptable to evaluate the design changes related to inadvertent dispensing of tablets. In March 2015, we received additional correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. As a result of this most recent FDA communication and the need for clarity with the FDA, the Zalviso NDA resubmission is on hold. We will provide an update on the timing of the resubmission of the Zalviso NDA after we obtain more information from the FDA. The FDA has precleared certain aspects of our proposed Risk Evaluation and Mitigation Strategy, or REMS, and indicated that they will continue discussion of our proposed REMS after the Zalviso NDA has been resubmitted.

 

Zalviso

 

Zalviso is an investigational, pre-programmed, non-invasive system to allow hospital patients with moderate-to-severe acute pain to self-dose with sufentanil sublingual tablets to manage their pain. Zalviso is designed to help address certain problems associated with post-operative intravenous patient-controlled analgesia, by offering:

 

 

A high therapeutic index opioid: Zalviso uses sufentanil, an opioid that has a high therapeutic index. The therapeutic index is the ratio of the effective dose versus the lethal dose. In animal studies, the therapeutic index for sufentanil was approximately 100 times larger than fentanyl and 300 times larger than morphine.

 

 

A non-invasive route of delivery: Zalviso utilizes a sufentanil tablet which allows for a sublingual (under the tongue) route of delivery. Sufentanil is highly lipophilic which provides for rapid absorption in the fatty cells (or mucosal tissue) found under the tongue, and for rapid transit across the blood-brain barrier to reach the mu-opioid receptors in the brain. The sublingual delivery used by Zalviso provides rapid onset of analgesia. The sublingual delivery system also eliminates the risk of IV-related analgesic gaps and IV complications, such as catheter-related infections. In addition, because patients do not require direct connection to an IV patient-controlled analgesia, or PCA, infusion pump through IV tubing, Zalviso allows for ease of patient mobility.

 

 

A simple, pre-programmed PCA solution: Zalviso allows patients to self-dose sufentanil sublingual tablets via a pre-programmed, secure system designed to eliminate the risk of programming errors.

 

We submitted an NDA for Zalviso in September 2013 and, as mentioned above, the FDA issued a CRL for Zalviso on July 25, 2014. We have conducted additional Human Factors studies and bench testing to address the related issues within the CRL. As mentioned above, in March 2015 we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss the need for an additional clinical study, and the potential design and objectives of such a study.

The 505(b)(2) NDA submission for Zalviso is based on a development program that includes data from seven Phase 1 studies, three Phase 2 clinical trials, and three Phase 3 clinical trials. The Phase 3 trial program included two placebo-controlled efficacy and safety trials and one open-label active comparator trial, in which Zalviso was compared to IV PCA with morphine. To date, the Zalviso safety database includes more than 600 patients. Zalviso successfully achieved the primary efficacy endpoints for each of the Phase 2 and Phase 3 trials. A summary of the Phase 3 trials and results is as follows:

 

 

Active comparator trial (IAP309)—in November 2012, we reported top-line data demonstrating that Zalviso met its primary endpoint of non-inferiority in a Phase 3 open-label active comparator trial designed to compare the efficacy and safety of Zalviso (15 mcg/dose, 20 minute lock-out) to IV PCA with morphine (1mg/dose, 6 minute lock-out) for the treatment of moderate-to-severe acute post-operative pain immediately following major abdominal or orthopedic surgery.

 

 

Double-blind, placebo-controlled, abdominal surgery trial (IAP310)—in March 2013, we reported top-line data demonstrating that Zalviso met its primary endpoint in a pivotal Phase 3 trial designed to compare the efficacy and safety of Zalviso to placebo in the management of acute post-operative pain after major open abdominal surgery. Adverse events reported in the trial were generally mild or moderate in nature and similar in both placebo and treatment groups. Utilizing a randomized, double-blind, placebo-controlled design, this pivotal Phase 3 trial enrolled 178 adult patients at 13 U.S. sites.

 

 

Double-blind, placebo-controlled, orthopedic surgery trial (IAP311)—in May 2013, we reported top-line data demonstrating that Zalviso met its primary endpoint in a pivotal Phase 3 trial designed to compare the efficacy and safety of Zalviso to placebo in the management of acute post-operative pain after major orthopedic surgery. Utilizing a randomized, double-blind, placebo-controlled design, this pivotal Phase 3 trial enrolled 426 adult patients at 34 U.S. sites. Treatment-emergent adverse events were generally mild to moderate in nature and similar for the majority of adverse events between Zalviso and placebo-treated patients, despite the shorter duration of exposure in the placebo-treated patients caused by early termination due to inadequate analgesia.

 

In December 2013, we announced a commercial collaboration with Grünenthal, covering the territory of the European Union, certain other European countries and Australia for Zalviso for use in the management of moderate-to-severe acute pain within a hospital, hospice, nursing home or other medically supervised setting. We retain all rights in remaining countries, including the United States, Asia and Latin America. The collaboration included a Collaboration and License Agreement, or License Agreement, and a Manufacturing and Supply Agreement, or Supply Agreement.

 

Under the terms of the License Agreement, we received an upfront cash payment of $30.0 million in December 2013, and in the third quarter of 2014, we received a milestone payment of $5.0 million related to the Marketing Authorization Application, or MAA, submission to the European Medicines Agency, or EMA. We are eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA. If approved, we are eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts ($28.5 million) and net sales target achievements ($171.5 million). Grünenthal will also make tiered royalty, supply and trademark fee payments in the mid-teens up to the mid-twenties percent range, on net sales of Zalviso in the Grünenthal territory.

 

Grünenthal will be responsible for all commercial activities for Zalviso, including obtaining and maintaining pharmaceutical product regulatory approval in the Grünenthal territory. We will be responsible for obtaining and maintaining device regulatory approval in the Grünenthal territory and manufacturing and supply of Zalviso to Grünenthal for commercial sales.

 

In July 2014, Grünenthal filed an MAA with the EMA under the centralized procedure in the European Union, or EU, for Zalviso for the management of moderate-to-severe acute pain in adult patients in a medically-supervised environment. In the fourth quarter of 2014, Grünenthal received 120-day questions from the EMA per the EMA’s standard regulatory review process. We have been working with Grünenthal towards the submission of the response to the 120-day questions. Grünenthal is currently working to complete the response and submit it to the EMA by the end of March 2015. Assuming the EMA accepts this filing, we anticipate a Committee for Medicinal Products for Human Use, or CHMP, opinion in the summer of 2015 and a final decision by the EMA in the fall of 2015.

 

In association with potential commercialization of Zalviso in the European Union, we underwent a Conformite Europeenne approval process for the Zalviso device, more commonly known as a CE Mark approval process. In December 2014, we received CE Mark approval, which permits the commercial use of the Zalviso device in the European Union. However, as a drug-device combination product, Zalviso will not be utilized commercially unless and until the EMA approves the Zalviso MAA. In connection with the CE Mark approval, we were also granted International Standards Organization, or ISO, 13485:2003 certification of our quality management system in November 2014. This is an internationally recognized quality standard for medical devices issued by our notified body, the British Standards Institution, or BSI.

 

ISO 13485:2003 certification recognizes that consistent quality policies and procedures are in place for the development, design and manufacturing of medical devices. The certification indicates that we have successfully implemented a quality system that conforms to ISO 13485 standards for medical devices. Certification to this standard is one of the key regulatory requirements for a CE Mark in the European Union as well as to meet equivalent requirements in other international markets. The certification applies to the Redwood City, California location which designs, manufactures and distributes finished medical devices.

ARX-04

 

We are also developing a Sufentanil Sublingual Single-Dose Tablet, or ARX-04, for the treatment of moderate-to-severe acute pain to be administered by a healthcare professional to a patient in settings of acute pain, such as in the emergency room, hospital floor, ambulatory care environment, or on the battlefield. In December 2013, we completed an End-of-Phase 2 Meeting with the FDA to identify a Phase 3 program pathway forward for evaluation of ARX-04. We plan to initiate a pivotal Phase 3 trial for ARX-04 in patients with post-operative pain following abdominal surgery by the end of March 2015. Pending completion of enrollment, we anticipate top-line data from this study in the fourth quarter of 2015.

 

We have also been notified by the Department of Defense, or DoD, that they are preparing a contract to provide partial funding to support further development of ARX-04. We are currently engaged in the contracting process with the DoD to determine the nature, scope, amount and timing of the contract.

 

Phase 3 Program

 

 

In June 2014, we completed a pharmacokinetic study in support of the ARX-04 development program. In this study of healthy volunteers, it was shown that two sublingual administrations of a Zalviso 15mcg sufentanil sublingual tablet dosed 20 minutes apart were comparable, in terms of area under the plasma concentration time curve, or AUC, exposure and peak plasma concentration, to one sublingual administration of an ARX-04 30mcg sufentanil sublingual tablet. We have proposed the inclusion of approximately 300 patients from the Zalviso clinical program in the ARX-04 safety database to the FDA and we have designed the two Phase 3 ARX-04 trials accordingly. The ARX-04 safety database required by the FDA is 500 patients. We have confirmation from FDA that some of the Zalviso patients can be included in the overall ARX-04 safety database; however, further discussion is needed to determine the exact number of such patients that can be used towards achieving the 500 patient minimum total safety exposure number required for ARX-04. Based on an ongoing pharmacokinetic analysis, we may need to increase enrollment in our planned Phase 3 clinical trial program to meet the FDA’s requested exposure requirements to ARX-04.

 

 

We plan to initiate a Phase 3 clinical trial, a double-blind, placebo-controlled efficacy and safety study of patients with post-operative pain following abdominal surgery by the end of March 2015. We expect top-line data from this trial in the fourth quarter of 2015. Approximately 160 patients are planned to be enrolled in this study.

 

 

In the first half of 2015, contingent on DoD funding, we plan to initiate our second planned Phase 3 clinical trial, an open-label safety study of patients who present to the emergency room with moderate-to-severe pain due to trauma or injury. We expect top-line data from this trial in the second half of 2015. Approximately 40 patients are planned to be enrolled in this study. Timing of this trial is currently pending finalization of the DoD contract. Should we experience delays in such contract negotiations, we may elect to delay this Phase 3 trial beyond the first half of 2015.

 

Phase 2 Clinical Study Results

 

In April 2013, we reported top-line data showing that the primary endpoint was achieved in a placebo-controlled, dose-finding, Phase 2 clinical trial of ARX-04 for acute pain. This trial randomized 101 patients following bunionectomy surgery in a 2:2:1 ratio to 30 mcg sufentanil sublingual tablet, 20 mcg sufentanil sublingual tablet, or placebo treatment arms. Ninety-one percent of patients entering the trial completed the 12-hour trial period.

 

Results demonstrated that patients receiving 30 mcg sufentanil sublingual tablet doses, administered by a healthcare professional, no more frequently than once per hour, had significantly greater pain reduction as measured by Summed Pain Intensity Difference to baseline during the 12-hour trial period (SPID-12) than placebo-treated patients (p=0.003). 

 

 

Adverse events, or AEs, reported in the trial were generally mild-to-moderate in nature, with two serious adverse events, or SAEs, of post-surgical infection reported, both of which were determined by the investigator to be unrelated to trial drug.

 

Research and development of ARX-04, including the Phase 2 trial and pre-Phase 3 development, was funded by a $5.6 million grant from the U.S. Army Medical Research and Materiel Command, or USAMRMC. As of December 31, 2013, we had recognized the full amount of the grant of $5.6 million.

 

ARX-02 and ARX-03

 

In addition to ARX-04, our product candidate pipeline consists of two other sufentanil-based sublingual product candidates. The Sufentanil Sublingual Tablet Breakthrough Pain, or BTP, Management System, or ARX-02, is a pain management system for the treatment of cancer patients who suffer from BTP. The Sufentanil/Triazolam Sublingual Tablet, or ARX-03, is a single, fixed-dose, combination drug product designed to provide mild sedation, anxiety reduction and pain relief for patients undergoing painful procedures in a physician’s office. We have successfully completed Phase 2 clinical trials for ARX-02 and ARX-03. Future development of ARX-02 and ARX-03 is contingent on funding from a corporate partnership or other external funding source.

Sufentanil Sublingual Tablets

 

Sufentanil, a high therapeutic index opioid, which has no active metabolites, is 5 to 10 times more potent than fentanyl and is used intravenously as a primary anesthetic to produce balanced general anesthesia for surgery, and for epidural administration during labor and delivery. Sufentanil has many pharmacological advantages over other opioids. Published studies demonstrate that sufentanil produces significantly less respiratory depressive effects relative to its analgesic effects compared to other opioids, including morphine, alfentanil and fentanyl. These third party clinical results correlate well with preclinical trials demonstrating sufentanil’s high therapeutic index, or the ratio of the toxic dose to the therapeutic dose of a drug, used as a measure of the relative safety of the drug for a particular treatment. Accordingly, we believe that sufentanil can be developed to provide an effective and well-tolerated treatment for acute pain. The following table illustrates the difference between the therapeutic index of different opioids.

In addition, the pharmaceutical attributes of sufentanil, including lipid solubility and ionization, result in rapid cell membrane penetration and onset of action, which we believe make sufentanil an optimal opioid for the treatment of acute pain.

 

Although the analgesic efficacy and safety of sufentanil have been well established, the product’s use has been historically limited due to its short duration of action when delivered intravenously. Sublingual delivery of sufentanil avoids the high peak plasma levels and short duration of action of IV administration.

 

 

Our portfolio of product candidates leverages the above mentioned advantages of sufentanil delivered via the sublingual route. We believe our non-invasive, proprietary sufentanil tablet sublingual dosage form potentially overcomes many of the limitations of current treatment options available for acute pain.

 

 

 
None of our product candidates have been approved by the United States Food and Drug Administration, or FDA. We have not generated any revenue from the sale of any of our product candidates.

Sublingual Delivery of Sufentanil: Summary of Phase 1 Clinical Studies Results

 

We have completed seven Phase 1 studies with our proprietary sufentanil sublingual tablets to support our four product candidates under development. These studies demonstrated desirable and consistent pharmacokinetic, or PK,
parameters, including:

 

 

relatively high bioavailability via the oral mucosa and very low gastrointestinal, or GI, bioavailability;

 

 

prolonged plasma levels relative to IV delivery;

 

 

PK parameters proportional to dose across a wide range of doses (2.5 mcg to 80 mcg);

 

 

lower peak plasma concentration, or Cmax, than IV delivery;

 

 

time to maximum plasma concentrations, or Tmax, range from 20 to 120 minutes;

 

 

while clearance increased in younger patients and heavier patients, clearance was not affected by race, sex, renal or hepatic parameters or concomitant CYP3A4 substrates;

 

 

slightly increased Cmax and prolonged half-life with concomitant administration of the CYP3A4
inhibitor ketoconazole;

 

 

lack of drug accumulation with repeat-dosing and achievement of steady-state plasma concentrations after the 13th dose (with 20 minutes between dosings);

 

 

relatively low patient to patient variability in Tmax and Cmax; and

 

 

repeat dosing PK that supports a 20-minute minimum re-dosing interval.

 

 

The chart below illustrates the PK profile of sufentanil sublingual tablets compared to IV delivery of sufentanil from one of our completed Phase 1 PK studies.

 

 

 In summary, we have demonstrated that sublingual delivery of sufentanil avoids the high peak plasma levels and short duration of action of IV administration, potentially enabling broader use of sufentanil. Our proprietary sufentanil sublingual tablet dosage form is a very small disc-shaped tablet with a bioadhesive excipient, or inactive ingredient, which enables the tablet to adhere to mucosal tissues. When placed under the tongue, the sufentanil sublingual tablet imbibes saliva, adhering it to the sublingual tissues and forming a hydrogel patch. Sufentanil, from the sublingual tablet, rapidly deposits into the fatty tissues under the tongue. The drug then absorbs into the plasma over several hours at roughly the same rate as it is being redistributed and/or cleared from the plasma resulting in a plateau plasma concentration from approximately 20 to 120 minutes. The sufentanil sublingual tablet fully disintegrates within 5-10 minutes. The small size of the sufentanil sublingual tablet, pictured above, is designed to minimize the saliva response and amount of sufentanil swallowed, resulting in high oral transmucosal uptake, whereby a majority of the drug is absorbed via the oral tissues ultimately into the bloodstream, and thereby provides consistent pharmacokinetics.

ARX-04

 

Sufentanil Sublingual Single-Dose Tablet

 

Moderate-to-severe acute pain

 

In April 2013, we reported that a Phase 2 trial of ARX-04 in patients after bunionectomy surgery achieved its primary endpoint. The FDA agreed that this was a well-controlled study and could be used as a pivotal study.

 

We plan to initiate a Phase 3 clinical trial that will evaluate the efficacy and safety of ARX-04 vs. placebo for the treatment of moderate-to-severe acute pain following ambulatory abdominal surgery by the end of March 2015, with top-line data anticipated in the fourth quarter of 2015, pending completion of enrollment. This trial was designed as the second of two well-controlled studies required for potential NDA filing for ARX-04, the first was the bunionectomy Phase 2 study.

 

We plan to initiate our second planned Phase 3 clinical trial, an open-label safety study of patients who present to the emergency room with moderate-to-severe pain due to trauma or injury in the first half of 2015, with top-line data anticipated in the second half of 2015, contingent on DoD funding. This study is not required to satisfy the regulatory requirements for ARX-04. Timing of this trial is currently pending finalization of the DoD contract. Should we have delays in such contract negotiations we may elect to delay this Phase 3 trial beyond the first half of 2015.

The Market Opportunity for Zalviso

 

According to the 2014 Decision Resources Acute Pain Report, or 2014 DR Report, the acute pain market (represented by treatments for post-operative pain, acute musculoskeletal pain and cancer breakthrough pain) in the United States, Europe and Japan realized 2013 revenues of $12.7 billion, and is expected to reach approximately $13.3 billion by 2023. Opioid analgesic use dominates the management of acute pain, representing 44% of the 2013 market, and is projected to grow to 46% of the 2023 market. Post-operative acute pain treatment in the United States is projected to grow significantly in the 2013 to 2023 period, from management of 13.8 million procedures in 2011 to 16.0 million procedures in 2023, a 1.5% CAGR. Despite its size, this market remains underserved. Studies report that up to 75% of patients experience inadequate pain relief after surgery. Inadequate pain relief can lead to decreased mobility, which increases the risks of other medical complications, including deep vein thrombosis and partial lung collapse, and can result in extended hospital stays. Additionally, based on an analysis of data published in 2008 from the World Health Organization, we estimate that there are approximately 27 million surgical procedures annually in other moderate-to-high per capita healthcare expenditure nations in which patients experience moderate-to-severe pain.

 

In the United States, we estimate that approximately one third of all procedures conducted are orthopedic in nature, one third are gastrointestinal, obstetric or gynecologic, and the remaining third are a mix of spinal, cardiothoracic and other procedures. Commissioned market research targeting surgeons and anesthesiologists has identified a consistent positive response to the attributes of Zalviso and indicates an interest in using Zalviso in at least 75% of their eligible patients. Additional market research indicated that physicians expressed interest in using Zalviso for patients who stay in the hospital for less than 24 hours and are not traditionally treated with IV PCA. Regardless of size or affiliation of hospitals, the majority of Pharmacy and Therapeutics, or P&T, committees we surveyed were likely to review and approve Zalviso, subject to demonstration of satisfactory pharmacoeconomic value.

 

 

How Zalviso Addresses the Unmet Medical Need in Moderate-To-Severe Acute Pain Management in a Hospital Setting

 

Hospitalized patients in moderate-to-severe acute pain could significantly benefit from the following items:

 

 

more rapid onset of analgesia;

 

 

fewer medication errors, especially relating to the use of opioids;

 

 

fewer side effects, including infection and bleeding risks due to invasive routes of delivery;

 

 

enhanced ability for patients to ambulate after surgery and avoid falls; and

 

 

patient control over their pain medication which has been shown to increase patient satisfaction.

 

For example, epidural catheters delivering local anesthetic are invasive and have a significant risk of lower extremity weakness and tethering the patient to a pump attached to an IV pole, creating multiple mobility impediments and fall risks; nerve blocks of the lower extremities (e.g., femoral nerve blocks) are also invasive and create weakness and fall risks; oral multimodal analgesia is not patient-controlled, is nurse-intensive and suffers from slow onset of action. While IV PCA does allow patient control over their pain medication, it suffers from the following:

 

 

side effects associated with the most commonly used opioid, morphine, and its active metabolites;

 

 

infection risk, analgesic gaps and decreased mobility associated with the invasive nature of IV delivery; and

 

 

medication errors, which in some instances may be fatal, due to the complexity of IV PCA pumps, many of which arise from programming errors.

 

 
10

 

 

In our clinical studies, Zalviso has demonstrated the following attributes:

 

 

a rapid onset of effect in comparison to intravenous delivery of morphine, and an ability to control pain as a monotherapy after moderate to severely painful surgeries such as knee replacement or colectomies;

 

 

an ability for young and old patients alike to use Zalviso;

 

 

a low rate of severe adverse event experiences;

 

 

a rate of adverse events that is similar to a placebo-treated patient population, with the exception of opioid
induced itching;

 

 

a high level of Patient Satisfaction as a result of Zalviso usage under patient control to manage pain after surgery over 48 to 72 hours; and

 

 

a high Nurse Ease of Care rating for ease of set-up and use of Zalviso by the health care professional.

 

According to published literature, the estimated annual error rate is 407 errors per 10,000 people treated with IV PCA in the United States. Published analysis of MEDMARX from 2000 to 2005 reveals that IV PCA errors represent a four-fold higher relative risk of harm compared to all other medication errors. The most recent published analysis of the FDA MAUDE database reports that 5% of IV PCA operator errors reported during a two-year index period, from 2002 to 2003, resulted in patient deaths. Approximately 56,000 adverse events were reported to the FDA between 2005 and 2009, prompting 70 Class II recalls of infusion pump devices that could cause temporary or reversible adverse effects and 14 Class I recalls of infusion pump devices that could cause serious injury or death. These issues with infusion pumps have resulted in the issuance of new draft guidance by the FDA, significantly increasing the data required to be submitted by IV PCA pump manufacturers to address safety problems.

 

Zalviso has the potential to address many of the key disadvantages of IV PCA, including:

 

 

eliminating the risk of IV PCA related infections, reducing analgesic gaps and enhancing mobility; and

 

 

eliminating the risk of programming errors.

 

 

We believe that Zalviso provides a favorable safety, efficacy and tolerability profile, potentially enabling Zalviso to become a new standard of care for moderate to severe acute pain control via patient-controlled analgesia.

 

Zalviso Description

 

The benefits of Zalviso are the result of combining the following three elements:

 

 

sufentanil, a high therapeutic index opioid;

 

 

Sufentanil sublingual tablets, our proprietary, non-invasive sublingual dosage form; and

 

 

our novel, pre-programmed, handheld PCA device that enables simple patient-controlled delivery of sufentanil sublingual tablets in the hospital setting and eliminates the risk of programming errors.

 

Zalviso allows patients to self-administer sufentanil sublingual tablets as needed to manage their moderate-to-severe acute pain in the hospital setting, and provides the record-keeping attributes of a conventional IV PCA pump while avoiding some of the key issues, such as programming errors, associated with conventional IV PCA use.

 

Zalviso utilizes sufentanil, which has one of the highest therapeutic indices of all commercially available opioids, making it an attractive candidate for the management of post-operative pain. Formulated in our proprietary sublingual tablet dosage form, sufentanil provides for relatively high bioavailability, with lower peak drug levels and a longer duration of action compared to IV delivery.

 

 
11

 

 

The Zalviso System consists of the following components: a disposable dispenser tip (Figure A); a disposable dispenser cap (Figure B); an adhesive thumb tag (Figure C); a cartridge of 40 sufentanil sublingual 15 mcg tablets (approximately a two-day supply) in a disposable radio frequency identification and bar-coded cartridge (Figure D); a reusable, rechargeable handheld controller (as pictured, nurse-side view) (Figure E); a tether (Figure F); and an authorized access card (Figure G).

 

 

This product candidate has not been approved by the FDA. We have not generated any revenue

from the sale of any of our product candidates.

 

Drugs are classified or scheduled by the Drug Enforcement Agency, or DEA, according to their potential for abuse and addiction. Sufentanil is scheduled as a class II opioid. Scheduled drugs, when they are under patient control in a hospital setting, must be secured and have adequate dose access control and tracking mechanisms. Our novel handheld PCA device has the following safety features:

 

 

an authorized access card, which is a wireless system access key for the healthcare professional;

 

 

a wireless, electronic, adhesive thumb tag that acts as a single-patient identification key;

 

 

pre-programmed 20-minute lock-out to avoid overdosing;

 

 

 

tablet singulation, or dispensing, motion that eliminates runaway motor delivery risk;

 

 

a security tether that is designed to prevent theft and misuse; and

 

 

fully automated inventory record of sufentanil sublingual tablet usage.

 

To set up Zalviso, the nurse or healthcare professional turns on the controller and follows the simple step-by-step instructions on the color graphical user interface screen described below:

 

 

retrieve the sufentanil sublingual tablet cartridge from secure drug storage;

 

 

lock the cartridge and dispenser into the controller; and

 

 

set up the secure patient access system, which is comprised of a security tether and a wireless, electronic, adhesive thumb tag that acts as a single-patient identification key.

 

To use Zalviso, the patient would:

 

 

confirm that the green indicator light is illuminated, meaning the device is available to dose;

 

 

place dispenser tip under tongue and push the large button on the controller with the thumb to which the thumb tag has been applied, which in turn dispenses a single sufentanil sublingual tablet;

 

 

remove the device from mouth upon hearing a tone confirming delivery of the sufentanil sublingual tablet; and

 

 

see the blue indicator light illuminate, indicating no new dose can be dispensed for the next 20 minutes.

 

Zalviso—Development Status

 

We submitted an NDA for Zalviso in September 2013 and, as mentioned above, the FDA issued a CRL for Zalviso on July 25, 2014. In March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study.

The 505(b)(2) NDA submission for Zalviso is based on a development program that includes data from seven Phase 1 studies, three Phase 2 clinical trials, and three Phase 3 clinical trials. The Phase 3 trial program included two placebo-controlled efficacy and safety trials and one open-label active comparator trial, in which Zalviso was compared to IV PCA with morphine. To date, the Zalviso safety database includes more than 600 patients. Zalviso successfully achieved the primary efficacy endpoints for each of the Phase 2 and Phase 3 trials.

 

 

Zalviso—Clinical Program

 

Summary

 

Our Phase 3 program for Zalviso consisted of three Phase 3 clinical trials. We have reported positive top-line results from each of the three clinical trials. Prior to our Phase 3 program, we completed three successful Phase 2 clinical trials of sufentanil sublingual tablets in the post-operative setting. These Phase 2 clinical trials demonstrated analgesic efficacy over a 12-hour study period, a low adverse event profile and excellent device functionality. During our End of Phase 2 meeting with the FDA, the FDA stated that the demonstration of efficacy versus placebo in two Phase 3 clinical trials with a total safety database of at least 600 patients exposed to the active drug should suffice to support an NDA. We designed our Phase 3 clinical trials based on the feedback from the FDA.

 

Phase 3 Clinical Trials for Zalviso

 

Active comparator trial (IAP309)

 

In November 2012, we reported top-line data showing that Zalviso had met its primary endpoint of non-inferiority in the Phase 3 open-label active comparator trial designed to compare the efficacy and safety of Zalviso (15 mcg/dose) to IV PCA with morphine (1mg/dose) for the treatment of moderate-to-severe acute post-operative pain. Utilizing a randomized, open-label, parallel group design, this trial enrolled 359 adult patients at 26 U.S. sites for the treatment of pain immediately following open-abdominal or major orthopedic surgery (hip and knee replacement). Patients were randomized 1:1 to treatment with Zalviso or IV PCA morphine and were treated for a minimum of 48 hours and up to 72 hours.

 

Regarding disposition and safety assessments, throughout the course of the trial, 7.3% of patients treated with Zalviso dropped out of the trial prematurely due to lack of efficacy compared to 8.9% of patients treated with IV PCA morphine. Additionally, 7.3% of the patients treated with Zalviso dropped out of the trial due to an adverse event compared to 10.0% of the IV PCA morphine patients. We observed 13 patients who experienced serious adverse events, or SAEs, in the trial, of whom three patients experienced serious adverse events assessed as possibly or probably related to the trial drug, one was related to Zalviso and two were related to IV PCA morphine. Overall the adverse events were similar between the two groups, however, continuous oxygen saturation monitoring demonstrated a lower percentage of patients with desaturations below 95% in the Zalviso group compared to IV PCA morphine (p = 0.028).

 

The primary endpoint for the trial was a comparison of the patient’s response using the Patient Global Assessment, or PGA, of method of pain control over the 48-hour trial period between the patients treated with Zalviso and IV PCA morphine. The PGA uses a 4-point scale of poor, fair, good or excellent to rate each method of pain control. The primary endpoint was determined by measuring the proportion of patients who responded “good” or “excellent” using the PGA to rate their method of pain control. An overview of the top-line primary endpoint results of this Phase 3 clinical trial demonstrates that:

 

 

Zalviso was non-inferior (p<0.001) to IV PCA morphine for the primary endpoint of PGA comparison over the 48-hour study period as determined by the combined percentage of patients with PGA ratings of “good” or “excellent” (78.5% vs. 65.6%, respectively). A p-value is a probability with a value ranging from 0 to 1, which indicates the likelihood that a clinical trial is different between treatment and control groups. P-values below 0.05 mean that there is a 95% or greater chance that there is a true difference between the groups, and are typically referred to as statistically significant.

 

 

The assessment of non-inferiority was based on a lower limit of—15% for the 95% confidence interval, or CI, around the difference between these percentages. Because the 95% CI was +3.7% to +22.1% for the 48 hour PGA and therefore did not cross the zero difference line, a secondary comparison of the primary endpoint, specifically a statistical analysis of superiority could be performed. In this trial, Zalviso was statistically superior to IV PCA morphine for the PGA endpoint (p=0.007). Statistically superior PGA was also seen at the 24 hour and 72 hour time points.

 

 

A number of secondary endpoints were also evaluated, including pain intensity difference, or PID, and pain relief at each evaluation time point, comparison of individual PGA ratings, a Healthcare Professional Global Assessment, or HPGA, of method of pain control, dropouts from the trial due to inadequate analgesia and adverse events, and Patient and Nurse Ease of Care Questionnaires using a validated questionnaire methodology specifically to evaluate PCA systems.

 

 
13

 

 

Zalviso had a significantly more rapid onset of action based on both PID and pain relief scores from 1 to 4 hours after initiation of dosing compared to IV PCA morphine (PID: p < 0.001 for 1 and 2 hours and p = 0.002 at 4 hours; pain relief: p = 0.003 at 1 hour and p < 0.001 at 2 and 4 hours). Zalviso achieved a PGA rating of “excellent” in 42.9% of treated patients, compared to 30.6% for IV PCA with morphine, with a p-value of 0.016.

 

The Healthcare Professional Global Assessment, or HPGA, was measured at 24, 48 and 72 hours, and produced similar results to the Patient Global Assessment. HPGA ratings of “good” or “excellent” at 48 hours were 81.4% for Zalviso compared to 70.0% for IV PCA morphine. An assessment of non-inferiority was conducted and demonstrated that Zalviso was non-inferior to IV PCA morphine (p < 0.001) in the trial. Because the 95% CI was +2.6% to +20.2% for the 48 hour HPGA and therefore didn’t cross the zero difference line, a statistical analysis for superiority could be performed, which demonstrated that for this trial, Zalviso was statistically superior to IV PCA morphine for the HPGA endpoint at 48 hours (p=0.012). Statistically superior HPGA was also seen at the 24 hour and 72 hour time points.

 

The Patient Ease of Care Questionnaire, or Patient Questionnaire, asked patients to respond to 21 questions regarding aspects of analgesia and PCA systems using a zero to five rating scale, including statements such as, but not limited to, “pain woke me up from my sleep,” “the device was easy to use,” and “the device interfered with my ability to get out of bed and walk around.” Answers to the Patient Questionnaire were combined for an Overall Patient Ease of Care score. These Patient Questionnaire statements were also grouped into six validated subscales, such as “comfort with device,” “impact on movement,” and “knowledge and understanding.” Patients were also asked in this Patient Questionnaire to rate their Overall Satisfaction with the level of pain control and with the way in which the medication was administered during the trial.

 

The Nurse Ease of Care Questionnaire, or Nurse Questionnaire, asked nurses to respond to 21 questions regarding aspects of analgesia and PCA systems using a zero to five rating scale, including statements regarding the set-up and management of the systems and management of the patients. Answers to the Nurse Questionnaire were combined for an Overall Nurse Ease of Care score. These Nurse Questionnaire statements were grouped into two validated subscales entitled “time-consuming” and “bothersome.” Nurses were also asked in this Nurse Questionnaire to rate their Overall Satisfaction based on the level of pain control and with their overall satisfaction of the system.

 

An overview of results of the Patient and Nurse Questionnaires results includes:

 

 

Patients in the trial reported that they had significantly greater Overall Satisfaction with Zalviso compared to IV PCA morphine (4.15 vs. 3.84, respectively, out of a 0 to 5 scale, with a p-value equal to 0.004).

 

 

Patients in the trial reported that they had greater Overall Ease of Care with Zalviso compared to IV PCA morphine (4.45 vs. 4.07, respectively, out of a 0 to 5 scale, with a p-value less than 0.001).

 

 

Nurses managing patients in the trial reported they had significantly greater Overall Satisfaction with Zalviso compared to IV PCA morphine (3.92 vs. 3.35, respectively, out of a 0 to 5 scale, with a p-value less than 0.001).

 

 

Nurses managing patients in the trial reported they had greater Overall Ease of Care with Zalviso compared to IV PCA morphine (4.27 vs. 3.82, respectively, out of a 0 to 5 scale, with a p-value equal to 0.017).

 

 As noted above, additional subscale analyses were performed related to the Overall Ease of Care with Zalviso as reported by both nurses and patients. The results, as detailed in the tables below, demonstrate that all Patient Ease of Care subscales were significantly higher for Zalviso than for IV PCA morphine in the trial. For the Nurse Ease of Care subscales, nurses rated Zalviso significantly less bothersome than IV PCA morphine and there was a trend towards Zalviso being less time consuming than IV PCA morphine.

Double-blind, placebo-controlled, abdominal surgery trial (IAP310)

 

In March 2013, we reported top-line data results demonstrating that Zalviso met its primary endpoint in a pivotal Phase 3 trial designed to compare the efficacy and safety of Zalviso to placebo in the management of acute post-operative pain after major open abdominal surgery. Adverse events reported in the trial were generally mild or moderate in nature and similar in both placebo and treatment groups. Utilizing a randomized, double-blind, placebo-controlled design, this pivotal Phase 3 trial enrolled 178 adult patients at 13 U.S. sites for the treatment of acute post-operative pain immediately following major abdominal surgery. Patients were treated for post-operative pain for a minimum of 48 hours, and up to 72 hours. Patients were randomized 2:1, with 119 patients randomized to sufentanil sublingual tablet treatment and 59 to placebo treatment. Both treatments were delivered by the patient, as needed, using Zalviso with a 20-minute lock-out period. Patients in both groups could receive up to 2 mg morphine intravenously per hour as a rescue medication, the primary purpose of this rescue medication being to provide placebo-treated patients access to pain medication to enable them to stay in the trial as long as possible. Pre-rescue pain scores were imputed to minimize the impact of this rescue opioid on efficacy evaluations.

 

The primary endpoint evaluated pain intensity over the 48-hour study period compared to baseline, or Summed Pain Intensity Difference (SPID-48), in patients following major open abdominal surgery. Patients receiving sufentanil sublingual tablets demonstrated a significantly greater SPID-48 compared to placebo-treated patients during the study period (105.6 and 55.6, respectively; p=0.001).

 

A number of secondary endpoints were also evaluated, including SPID at 24 hours and 72 hours, PID and pain relief values for each evaluation time point, drop outs from the trial due to inadequate analgesia and adverse events, and Patient Ease of Care Questionnaires using a validated questionnaire methodology specifically to evaluate patient-controlled analgesia systems. A summary of the results for the secondary endpoints is as follows:

 

 

24 hours and 72 hours after first dose, SPID was significantly greater in the sufentanil sublingual tablet-treated patients than in the placebo-treated patients (p<0.001 and p=0.004, respectively).

 

 

PID and pain relief values separated statistically from placebo as early as 45 minutes (p=0.027 for both).

 

 

A summed pain relief measure over the 48-hour study period, commonly referred to as TOTPAR, was significantly greater for sufentanil sublingual tablet-treated patients than placebo-treated patients (p=0.002)

 

 

Eighty, or 70.2%, of the sufentanil sublingual tablet-treated patients completed the 48-hour study period, compared to 30, or 51.7%, of placebo-treated patients. Reasons for drop-out in the sufentanil sublingual tablet-treated and placebo-treated groups were adverse events (5.3% and 6.9%, respectively), lack of efficacy (16.7% and 31.0%, respectively) and other (7.9% and 10.3%, respectively).

 

 

Only one patient, in the sufentanil sublingual tablet-treated group, experienced a serious adverse event, which was determined to be unrelated to the study drug by the investigator.

 

 

Patients in the trial who were treated with sufentanil sublingual tablets reported an average Overall Ease of Care of 4.39 out of a 0 to 5 scale. In addition, patients in the placebo arm of the trial also reported favorable Overall Ease of Care scores, with an average score of 4.36. These results are comparable to the results from the active comparator trial, which is summarized above.

Double-blind, placebo-controlled, orthopedic surgery trial (IAP311)

 

In May 2013, we reported top-line data results demonstrating that Zalviso met its primary endpoint in a pivotal Phase 3 trial designed to compare the efficacy and safety of Zalviso to placebo in the management of acute post-operative pain after major orthopedic surgery. Adverse events reported in the study were generally mild or moderate in nature and were similar in both placebo and treatment groups for the majority of adverse events. Utilizing a randomized, double-blind, placebo-controlled design, this pivotal Phase 3 study enrolled 426 adult patients at 34 U.S. sites for treatment of moderate=to-severe acute pain immediately following major orthopedic surgery. Seven patients did not receive study drug, resulting in 419 patients being included in the intent-to-treat (ITT) population. Patients were treated for a minimum of 48 hours, and up to 72 hours. Patients were randomized 3:1, with 315 patients randomized to sufentanil sublingual tablet treatment and 104 to placebo treatment. Both treatments were delivered by the patient, as needed, using the Zalviso System with a 20-minute lock-out period. Patients in both groups could receive up to 2 mg morphine intravenously per hour as a rescue medication, the primary purpose of this rescue medication being to enable placebo-treated patients to stay in the study. Pain scores recorded just prior to the delivery of rescue medication were gathered and imputed forward to minimize the impact of this rescue opioid on efficacy evaluations.

 

The primary endpoint evaluated pain intensity over the 48-hour study period compared to baseline, or Summed Pain Intensity Difference (SPID-48), in patients following major orthopedic surgery. Patients receiving Zalviso demonstrated a significantly greater SPID-48 compared to placebo-treated patients during the study period (+76.1 and -11.5, respectively; p < 0.001). Two hundred fifteen (68.3%) sufentanil sublingual tablet-treated patients completed the 48-hour study period, compared to 43 (41.3%) placebo-treated patients. Primary reasons for drop-out in the sufentanil sublingual tablet- and placebo-treated groups were adverse events (7.0% and 6.7%, respectively) and lack of efficacy (14.3% and 48.1%, respectively).

 

Secondary endpoint data included PID and pain relief values for each evaluation time point and demonstrated that PID separated from placebo at 1 hour (p = 0.03) and pain relief separated at 45 minutes (p < 0.01). SPID at 24 and 72 hours was also assessed and was highly significant as illustrated below.

ARX-04—Sufentanil Sublingual Single-Dose Tablet

   

This product candidate has not been approved by the
FDA. We have not generated any revenue from the
sale of any of our product candidates.

The Market Opportunity for ARX-04

 

We believe that ARX-04 could be useful in a variety of medically supervised settings, including in the emergency room, for post-operative patients who are transitioning from the operating room to the recovery floor, or who are recovering from either short-stay or ambulatory surgery, and do not require more long-term patient-controlled analgesia, as well as for battlefield casualty treatment, and by paramedics during patient transport. According to the National Emergency Department Sample, or NEDS, there were more than 104 million adult emergency room visits in the United States during 2011, of which it is estimated that more than 48 million were associated with moderate-to-severe acute pain; while in the EU there were more than 91 million adult emergency room visits in the United States during 2011, of which it is estimated that more than 34 million were associated with moderate-to-severe acute pain. Based on the National Survey of Ambulatory Surgery, in 2006, an estimated 27 million adult patients underwent outpatient surgical procedures in the United States, while in the EU, an estimated 12 million adult patients underwent outpatient surgical procedures. Of these, we estimate more than 11 million patients experienced moderate-to-severe pain in the United States, and nearly 3 million patients in the EU experienced moderate-to-severe pain. According to the National Inpatient Sample, in 2011, more than 15 million adult patients in the United States underwent surgical procedures in an inpatient setting, while more than 17 million adult patients underwent surgical procedures in an inpatient setting in the EU. Of these, it is estimated that more than 7 million of these procedures performed in the United States resulted in moderate-to-severe pain, while more than 8 million of these procedures performed in the EU resulted in moderate-to-severe pain.

How ARX-04 Addresses the Unmet Medical Need for Moderate-to-Severe Acute Pain

 

ARX-04 is a non-invasive, fast-onset sufentanil sublingual tablet product candidate for treatment of patients with moderate-to-severe acute pain. In the emergency room and in ambulatory care environments, patients often do not have immediate IV access available, or maintaining IV access can be an impediment to rapid discharge. Oral pills and liquids generally have slow and erratic onset of analgesia. Even patients with IV access may have undesirable side effects with the commonly used IV opioids morphine and hydromorphone, such as sedation or oxygen desaturation. Moreover, IV dosing results in high peak plasma levels, thereby limiting the opioid dose and requiring frequent redosing intervals to titrate to satisfactory analgesia. Additional treatment options are needed that can safely and rapidly treat acute trauma pain, in both civilian and military settings.

 

ARX-04 Description

 

ARX-04 is a non-invasive, fast-onset sufentanil sublingual tablet product candidate for treatment of patients with moderate-to-severe acute pain, in medically supervised settings of trauma or injury, such as the emergency room, or for post-operative patients who are transitioning from the operating room to the recovery floor, or who are recovering from either short-stay or ambulatory surgery, and do not require more long-term, patient-controlled analgesia, as well as for battlefield casualty treatment, and by paramedics during patient transport. ARX-04 features sufentanil, a high therapeutic index opioid, in our proprietary sufentanil sublingual tablet technology that enables rapid sublingual absorption when the tablet is placed under the tongue. As a result, sufentanil sublingual tablets can provide rapid onset of analgesia and display a consistent pharmacokinetic profile due to a high percentage of drug being absorbed sublingually instead of through the gastrointestinal tract.

 

ARX-04 Clinical Program

 

Summary

 

We plan to initiate our first Phase 3 clinical trial for ARX-04 by the end of March 2015. Pending the completion of enrollment in this study, we anticipate top-line results in the fourth quarter of 2015.

 

In May 2011, we received a $5.6 million grant from the US Army Medical Research and Materiel Command, or USAMRMC, to conduct a Phase 2 dose-finding trial, and to prepare to enter Phase 3. In November 2012, we initiated the Phase 2 dose-finding trial and in April 2013, we announced that the trial achieved its primary endpoint.

 

As of December 31, 2013, we had recognized the $5.6 million grant in full.

 

Phase 3 Clinical Program for ARX-04

 

In December 2013 we completed an End of Phase 2 Meeting with the FDA to identify a Phase 3 program pathway forward for evaluation of ARX-04. Key outcomes from the End of Phase 2 Meeting included:

 

 

Agreement on a 500 subject safety database, 100 patients of whom would be studied with multiple doses
of ARX-04;

 

 

Agreement that the bunionectomy Phase 2 study was a well-controlled study and could be used as a pivotal study;

 

 

Agreement that a single additional Phase 3 pivotal efficacy and safety study in a model of visceral pain would be sufficient to support an NDA submission; and

 

 

Agreement that the primary endpoint in the remaining Phase 3 study could be the SPID-12, with secondary endpoints following patients out to 48 hours.

 

In June 2014, we completed a pharmacokinetic study in support of the ARX-04 development program. In this study of healthy volunteers, it was shown that two sublingual administrations of a Zalviso 15mcg sufentanil sublingual tablet dosed 20 minutes apart were comparable, in terms of AUC exposure and peak plasma concentration, to one sublingual administration of an ARX-04 30mcg sufentanil sublingual tablet. We have proposed the inclusion of approximately 300 patients from the Zalviso clinical program in the ARX-04 safety database to the FDA and we have designed the two Phase 3 ARX-04 trials accordingly. As mentioned above, the ARX-04 safety database required by the FDA is 500 patients. We have confirmation from FDA that some of the Zalviso patients can be included in the overall ARX-04 safety database; however, further discussion is needed to determine the exact number of such patients that can be used towards achieving the 500 patient minimum total safety exposure number required for ARX-04. Based on an ongoing pharmacokinetic analysis, we may need to increase enrollment in our planned Phase 3 clinical trial program to meet the FDA’s requested exposure requirements to ARX-04.

We plan to initiate a Phase 3 clinical trial, a double-blind, placebo-controlled efficacy and safety study of patients with post-operative pain following abdominal surgery, by the end of March 2015. The single Phase 3 pivotal study requested by the FDA, SAP301, is a multi-center, double-blind, placebo-controlled study that will evaluate the efficacy and safety of ARX-04 vs. placebo for the treatment of moderate-to-severe acute pain following ambulatory abdominal surgery. We anticipate that enrollment will take up to nine months. Pending the completion of enrollment in this study, we expect top-line data from this trial in the fourth quarter of 2015. Approximately 160 patients are planned to be enrolled in this study.

 

We have been notified by the DoD that they are preparing a contract to provide partial funding to support further development of ARX-04. We are engaged in the contracting process with the DoD to determine the nature, scope, amount and timing of the contract. As noted above, we plan to initiate a Phase 3 trial by the end of March 2015 so as to not sustain additional delays in the development of ARX-04 while we continue contract negotiations with the DoD. We believe the DoD can be supportive of key aspects of the continued development of ARX-04 but we do not currently have a timeline by which we may receive funding.

 

In the first half of 2015, contingent on DoD funding, we plan to initiate our second planned Phase 3 clinical trial, an open-label safety study of patients who present to the emergency room with moderate-to-severe pain due to trauma or injury. We expect top-line data from this trial in the second half of 2015. Approximately 40 patients are planned to be enrolled in this study. Timing of this trial is currently pending finalization of the DoD contract. Should we have delays in such contract negotiations, we may elect to delay this Phase 3 trial beyond the first half of 2015.

 

Phase 2 Clinical Trial for ARX-04

 

In April 2013, we announced top-line results demonstrating that a placebo-controlled, dose-finding, Phase 2 trial of our investigational single-dose sufentanil sublingual tablet for acute pain, ARX-04, successfully met its primary endpoint. Results demonstrated that patients receiving 30 mcg sufentanil sublingual tablet doses, administered by a healthcare professional, no more frequently than once per hour, had significantly greater pain reduction as measured by Summed Pain Intensity Difference to baseline during the 12-hour study period (SPID-12) than placebo-treated patients (+6.53 for 30 mcg sufentanil sublingual tablet-treated patients and -7.12 for placebo-treated patients; p=0.003). The 20 mcg sufentanil sublingual tablet-treated patients did not achieve SPID-12 scores that differentiated from placebo. Adverse events reported in the study were generally mild-to-moderate in nature, with two serious adverse events of post-surgical infection reported, both of which were determined by the investigator to be unrelated to study drug. This dose-ranging study randomized 101 patients following bunionectomy surgery in a 2:2:1 ratio to 30 mcg sufentanil sublingual tablet, 20 mcg sufentanil sublingual tablet or placebo treatment arms. The intent-to-treat (ITT) population in this study averaged 42.5 years of age and was evenly balanced for males and females (51%:49%). Ninety-one percent of patients entering the study completed the full 12-hour study period.

 

A number of secondary endpoints were also achieved, as follows:

 

For the time-weighted sum of pain relief scores over the 12-hour study period, or TOTPAR12, there was a statistically significant difference in favor of the 30 mcg group over placebo (9.73 vs. 4.37 p = 0.002). Patients treated with the 30 mcg dose of sufentanil sublingual tablet showed a rapid onset of action with a statistically significant beneficial difference in pain relief (p<0.001) and pain intensity (p<0.01) seen at 30 minutes after dosing compared to placebo. Dosing averaged every 2.4 hours over the duration of the 12-hour study. In addition, patient global assessment of the 30 mcg dose at 12 hours was superior to placebo (p=0.002) with 43.6% vs. 5.0% of the patients responding good or excellent for overall pain control. The 20 mcg dose was not significantly different from placebo for either endpoint.

 

Two SAEs, both in the 20 mcg-dose group, occurred one week after the study (surgical infections) and were deemed unrelated to study drug. All but two adverse events reported in the study were mild-to-moderate in nature with 58 patients (58%) reporting a total of 135 adverse events. The most frequently reported adverse events for all patients were nausea (30%), vomiting (17%), dizziness (14%) and somnolence (11%). Two patients discontinued treatment, one unrelated to study drug (anxiety/chest pain) and the other probably related to study drug (somnolence/respiratory depression), however both patients recovered without medical intervention.

ARX-02—Sufentanil Sublingual Tablet BTP Management System

   

This product candidate has not been approved by the
FDA. We have not generated any revenue from the
sale of any of our product candidates.

The Market Opportunity for ARX-02

 

According to the American Cancer Society, there were more than 1.5 million new cancer cases in the United States in 2010. It is estimated that over 625,000 of these cases result in patients who experience breakthrough pain. We estimate the prescription volume for oral transmucosal products for the management of cancer breakthrough pain to be 220,000 prescriptions per year. This suggests that less than 10% of cancer patients with cancer breakthrough pain are treated with approved transmucosal breakthrough pain medications. In addition, many physicians use immediate release oral opioids to treat cancer breakthrough pain. We believe that this market is significantly larger than the transmucosal product market. Market research among physicians managing cancer patients indicates that ARX-02 could capture approximately a quarter of the cancer breakthrough pain prescriptions. In this research, ARX-02 was predicted to take share equally from both the immediate release oral products and the transmucosal products.

 

ARX-02 Description

 

ARX-02 is a product candidate for the treatment of cancer patients who suffer from breakthrough pain. ARX-02 consists of a magazine containing 30 single dose applicators, or SDAs, loaded into a multiple SDA dispenser, or MSD. Each SDA includes a sufentanil sublingual tablet that a patient can self-administer to his or her sublingual space for oral transmucosal absorption. The MSD:

 

 

protects and dispenses SDAs, one at a time;

 

 

displays a recent dose indicator that is designed to mitigate overdosing;

 

 

has child-resistant, elderly-friendly features; and

 

 

provides electronic date and time stamping of each SDA removal event.

 

The date and time event log is designed to be retrieved from the MSD by a healthcare professional during an office visit to assist the prescriber in understanding the usage profile of the medication, including diversion or abuse. Overall, our goal is to improve the treatment of cancer breakthrough pain while adding a substantially heightened level of detection and deterrence around prescription opioid use, misuse and abuse. While the initial dispenser for outpatient use is designed for dispensing sufentanil sublingual tablets for cancer breakthrough pain events, we believe this concept could be adapted into developing dispensers for other scheduled drugs in the future.

 

ARX-02 Clinical Program Overview

 

We have completed a successful Phase 2 clinical trial of ARX-02. The primary endpoint in this trial was achieved and demonstrated that the time-weighted summed pain intensity difference over 30 minutes, or SPID-30, for sufentanil sublingual tablet-treated episodes was greater than placebo-treated episodes (p<0.001). In addition, pain intensity and pain relief were included as secondary endpoints. Lower scores for pain intensity were reported at each evaluation time point for sufentanil sublingual tablet-treated episodes compared to placebo-treated episodes (p=0.027 at 15 minutes and p<0.001 at all other time points). Time reported time-weighted total pain relief, or TOTPAR, was greater at all time points for sufentanil sublingual tablet-treated episodes compared to placebo-treated episodes (p=0.049 and p=0.009 for the 10 and 15 minute time points, respectively, and p=<0.001 for the remaining time points). The trial also demonstrated a low adverse event profile.

 

We held an End of Phase 2 meeting with the FDA in July 2010. The FDA stated that the demonstration of efficacy versus placebo in a single Phase 3 clinical trial with a total safety database of 300 to 500 patients exposed to active drug, with at least 100 patients treated for a minimum of three months, may support an indication for the treatment of cancer breakthrough pain with underlying chronic pain.

 

Further development of the ARX-02 program is contingent on identification of corporate partnership resources.

ARX-03—Sufentanil/Triazolam Sublingual Tablet

   

This product candidate has not been approved by the FDA. We have not generated any revenue from the sale of any of our product candidates.

The Market Opportunity for ARX-03

 

Each year in the United States, more than 100 million procedures take place in a physician’s office that are known to be anxiety-inducing and painful, according to commissioned market research data that was completed in 2010. These include diagnostic procedures such as breast and prostate biopsies, cosmetic procedures such as liposuction and dermal abrasions, interventional radiology procedures, and therapeutic procedures such as vasectomies and endometrial ablation procedures. IV sedative medications are typically not offered to these patients because of the high cost of the specialized personnel and monitoring equipment. Despite the high potential for pain and anxiety, most patients currently undergo these procedures with only a local anesthetic, resulting in unnecessary procedure discomfort. We believe there is significant opportunity for a fast-acting, effective and safe product that can provide mild levels of sedation, anxiety reduction and analgesia for painful procedures conducted in a physician’s office without the need for specialized personnel to monitor the patient.

 

ARX-03 Description

 

ARX-03 Sufentanil/Triazolam Sublingual Tablet is a single, fixed-dose sublingual product candidate designed to be administered by a healthcare professional prior to a painful procedure in a physician’s office. An important advantage of sufentanil and triazolam over other drugs in their classes is their rapid uptake from the sublingual mucosa. Our Phase 2 clinical data showed that administering ARX-03 via sublingual route prior to a procedure results in a rapid onset of mild sedation and reduction in anxiety in 15 to 30 minutes. Sufentanil and triazolam have short half-lives compared to many other agents in the same class of compounds, enabling patients treated with ARX-03 to be discharged immediately following completion of the procedure. The sublingual route of administration avoids the high plasma concentrations associated with IV delivery, thereby obviating the need for specialized personnel and extensive monitoring.

 

ARX-03 Clinical Program Overview

 

We have completed a successful Phase 2 clinical trial of ARX-03 demonstrating rapid onset of mild sedation and anxiety reduction, with a low adverse event profile during an abdominal liposuction procedure. In addition, we participated in an End of Phase 2 meeting with the FDA in May 2010 to discuss the Phase 3 clinical program and requirements for an NDA submission. Based on these discussions, two four-arm factorial Phase 3 clinical trials will be required with a minimum of 700 patients exposed to active drug.

 

Further development of the ARX-03 program is contingent on identification of corporate partnership resources.

 

Other Potential Applications for Our Sublingual Tablet Technology

 

We believe that as a platform technology, the Sublingual Tablet, either as a standalone dosage form or in conjunction with various forms of dispensing mechanisms, has the potential to enable other product candidates utilizing a number of additional compounds to be delivered sublingually to the oral mucosa. There are numerous compounds used for the treatment of pain as well as other therapeutic indications which are dosed in microgram quantities and possess characteristics that we believe make them potential candidates for sublingual delivery via the Sublingual Tablet.

 

Our Strategy

 

Our strategy is to develop and commercialize a portfolio of sufentanil sublingual tablet-based products and other products in hospital markets in the United States. We have designed and are developing product candidates that meet clearly defined unmet medical needs, have clearly defined clinical development programs, target large commercial market opportunities and require modestly-sized commercial organizations in the United States. We selectively utilize third party contractors in order to maximize the capital efficiency of our development and commercialization efforts. We plan to enter into partnerships to market our product candidates outside the United States. In December 2013, we announced a commercial collaboration with Grünenthal, covering the territory of the European Union, certain other European countries and Australia for Zalviso for potential use in pain treatment within or dispensed by a hospital, hospice, nursing home or other medically supervised setting. We retain all rights in remaining countries, including the United States. We continue to seek partnerships to market Zalviso in markets outside of the Grünenthal territory and the United States.

Zalviso 

 

Zalviso is our lead product candidate and we are seeking FDA approval for the use of Zalviso to treat moderate-to-severe acute pain in the hospital setting. We submitted an NDA for Zalviso in September 2013 and, as mentioned above, the FDA issued a CRL for Zalviso on July 25, 2014. In March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study.    

 

 

Our specific strategy with respect to Zalviso is to:

 

 

seek regulatory approval in the United States;

 

 

strengthen our commercial relationships for the manufacturing of the components and assembly of the
Zalviso System;

 

 

build a targeted hospital-directed sales force in the United States; and

 

 

collaborate with Grünenthal to seek regulatory approval for Zalviso in their licensed territories.

 

 

seek commercial partnerships for Zalviso in other unlicensed countries outside of the United States.

 

ARX-04

 

ARX-04 is a non-invasive, fast-onset sufentanil sublingual tablet product candidate for treatment of patients with moderate-to-severe acute pain, in medically supervised settings of trauma or injury, such as the emergency room, or for post-operative patients who are transitioning from the operating room to the recovery floor, or who are recovering from either short-stay or ambulatory surgery, and do not require more long-term, patient-controlled analgesia, as well as for battlefield casualty treatment, and by paramedics during patient transport. We plan to initiate our Phase 3 program for ARX-04 by the end of March 2015, and, pending completion of enrollment, we anticipate top-line results from this study in the fourth quarter of 2015.

 

We have been notified by the Department of Defense that they are preparing a contract to provide partial funding to support further development of ARX-04. We are engaged in the contracting process with the DoD to determine the nature, scope, amount and timing of the contract.

 

In the first half of 2015, contingent on DoD funding, we plan to initiate our second planned Phase 3 clinical trial, an open-label safety study of patients who present to the emergency room with moderate-to-severe pain due to trauma or injury. We expect top-line data from this trial in the second half of 2015. Approximately 40 patients are planned to be enrolled in this study. Timing of this trial is currently pending finalization of the DoD contract. Should we have delays in such contract negotiations, we may elect to delay this Phase 3 trial beyond the first half of 2015.

 

Our specific strategy with respect to ARX-04 is to:

 

 

complete our Phase 3 clinical program and seek regulatory approval in the United States;

 

 

further expand our relationship with our existing contract manufacturing organizations, or CMOs, for the manufacture of ARX-04;

 

 

leverage and build upon the targeted hospital-directed sales force we are building for Zalviso in the United States; and

 

 

seek commercial partnerships for ARX-04 in countries outside of the United States.

 

 

Further development of ARX-02 and ARX-03 will depend on the identification of a partner to support these efforts.

 

Sales and Marketing

 

We anticipate developing a distribution capability and commercial organization in the United States to market and sell our product candidates alone or with partners, while out-licensing commercialization rights outside of the United States. In executing our strategy, our goal is to have significant control over the development process and commercial execution for our product candidates, while retaining meaningful economics.

 

We plan to progressively build commercial capability to support introduction of Zalviso to the United States market as we move toward potential NDA approval. We foresee two stages of commercial execution to support successful introduction of Zalviso in the United States:

 

Prior to FDA approval of Zalviso, we plan to continue to:

 

 

highlight the clinical and health economic data identifying the limitations of IV PCA in use today;

 

 

increase awareness of the clinical profile of Zalviso through publication of our clinical data;

 

 

create and deploy a focused scientific support team to gather a detailed understanding of individual hospital needs in order to be prepared to present Zalviso effectively at the time of commercial launch;

 

 

establish advisory boards with anesthesiologists, surgeons, nurses and P&T committees to provide us with input on appropriate commercial positioning for Zalviso for each of these key audiences;

 

 

build a sales and marketing organization that can define appropriate segmentation and positioning strategies and tactics for Zalviso; and

 

 

design a post-approval clinical development program.

 

 
22

 

 

Assuming FDA approval, we plan to:

 

 

establish Zalviso on hospital formularies through deployment of an experienced team to explain the clinical and economic benefits of Zalviso in comparison to IV PCA;

 

 

create and progressively deploy a high-quality, customer focused and experienced sales organization dedicated to bringing innovative, highly-valued healthcare solutions to patients, payors and healthcare providers, including progressively building a targeted hospital-directed sales force of approximately 65 people in the United States;

 

 

conduct post-approval clinical trials for Zalviso;

 

 

establish Zalviso as the product of choice for traditional post-operative PCA; and

 

 

expand the market through deployment of Zalviso for 24-hour stay patients, and other in-hospital acute pain conditions.

 

 

Collaborative Arrangements

 

Grünenthal Collaboration

 

In December 2013, we announced a commercial collaboration with Grünenthal for Zalviso covering the countries of the European Union, Switzerland, Liechtenstein, Iceland, Norway and Australia, or the Territory, for human use in pain treatment within or dispensed by hospitals hospices, nursing homes and other medically-supervised settings, or the Field. The collaboration included a License Agreement and a Supply Agreement.

 

License Agreement. Under the terms of the License Agreement, Grünenthal has the exclusive right to commercialize Zalviso in the Field in the Territory. AcelRx retains control of clinical development, while Grünenthal will be responsible for certain development activities pursuant to a development plan to be agreed between the parties. Grünenthal is exclusively responsible for marketing approval applications and other regulatory filings relating to the sufentanil sublingual tablet drug cartridge for Zalviso in the Field in the Territory, while we are responsible for the CE Mark and other regulatory filings relating to device portions of Zalviso.

 

Grünenthal will have a right of first negotiation with respect to proposed exploitation in the Territory of Zalviso outside of the Field or the proposed exploitation in the Territory of another pharmaceutical product delivered with a PCA device for transmucosal application. Either party has the right to remove Australia from the Territory for purposes of the collaboration if Grünenthal’s marketing approval or commercialization activities do not meet specified timelines set forth in the GRT
License Agreement.

 

Under the terms of the License Agreement, we received an upfront cash payment of $30.0 million in December 2013, and in the third quarter of 2014, we received a milestone payment of $5.0 million related to the MAA submission. We are eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA. If approved, we are eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts and net sales target achievements. Grünenthal will also make tiered royalty, supply and trademark fee payments in the mid-teens up to the mid-twenties percent range, on net sales of Zalviso in the Territory.

 

Grünenthal will be responsible for all commercial activities for Zalviso, including obtaining and maintaining pharmaceutical product regulatory approval in the Territory. We will be responsible for obtaining and maintaining device regulatory approval in the Territory and manufacturing and supply of Zalviso to Grünenthal for commercial sales. A CE Mark (#611742) for Zalviso was obtained in the fourth quarter 2014 which specifies AcelRx as the device design authority and manufacturer.

 

Unless earlier terminated, the License Agreement continues in effect until the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments, which supply and trademark fee continues for so long as AcelRx continues to supply Zalviso to Grünenthal. The License Agreement is subject to earlier termination in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party, upon the bankruptcy or insolvency of either party, or by Grünenthal for convenience.

 

Manufacturing Agreement. Under the terms of the Manufacturing Agreement, we will manufacture and supply Zalviso for use in the Field for the Territory exclusively for Grünenthal. Grünenthal shall purchase from AcelRx, during the first five years after the effective date of the Manufacturing Agreement, 100% and thereafter 80% of Grünenthal’s and its sublicensees’ and distributors’ requirements of Zalviso for use in the Field for the Territory. Zalviso will be supplied at our fully burdened manufacturing cost (as defined in the Manufacturing Agreement). The Manufacturing Agreement requires us to use commercially reasonable efforts to enter stand-by contracts with third parties providing significant supply and manufacturing services and under certain specified conditions permits Grünenthal to use a third party back-up manufacturer to manufacture Zalviso for Grünenthal’s commercial sale in the Territory.

 

 
23

 

 

Unless earlier terminated, the Manufacturing Agreement continues in effect until the later of the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments or the end of any transition period for manufacturing obligations due to the expiration or termination of the License Agreement. The Manufacturing Agreement is subject to earlier termination in connection with certain termination events in the License Agreement, in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party or upon the bankruptcy or insolvency of either party.

 

Intellectual Property

 

We seek patent protection in the United States and internationally for our product candidates. Our policy is to pursue, maintain and defend patent rights developed internally and to protect the technology, inventions and improvements that are commercially important to the development of our business. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents granted to us in the future will be commercially useful in protecting our technology. We also rely on trade secrets to protect our product candidates. Our commercial success also depends in part on our non-infringement of the patents or proprietary rights of third parties. For a more comprehensive discussion of the risks related to our intellectual property, please see “Risk Factors—Risks Related to Our Intellectual Property” appearing elsewhere in this Form 10-K.

 

Our success will depend significantly on our ability to:

 

 

obtain and maintain patent and other proprietary protection for our product candidates;

 

 

defend our patents;

 

 

preserve the confidentiality of our trade secrets; and

 

 

operate our business without infringing the patents and proprietary rights of third parties.

 

We have established and continue to build proprietary positions for our product candidates and related technology in the United States and abroad.

 

As of December 31, 2014, we are the owner of record of 16 issued U.S. patents, which provide coverage for sufentanil sublingual tablets, the device components of Zalviso and of ARX-02, ARX-03 and ARX-04 Tablet Single Dose Applicator, or SDA. These patents provide coverage through at least 2027. We also hold four issued European patents, each valid in at least six countries in Europe. In addition, we own five patents in Japan, four in China and three in Korea, and a number of other international patents which provide coverage through at least 2027. We are also pursuing a number of U.S. and foreign patent applications. The patent applications that we have filed and have not yet been granted may fail to result in issued patents in the United States or in foreign countries. Even if the patents do successfully issue, third parties may challenge the patents.

 

We continue to seek and expand our patent protection for both compositions of matter and delivery devices, as well as methods of treatment related to our product candidates. In particular, we are pursuing additional patent protection for our ARX-01, ARX-02, ARX-03 and ARX-04 sufentanil sublingual tablets and sufentanil/triazolam sublingual tablets and formulations, our Zalviso device, the combination of drugs and our Zalviso device, our ARX-02, ARX-03 and ARX-04 SDA, as well as to methods of treatment using such drug and device compositions.

 

We have filed for additional patent coverage in the United States, Europe as well as many other foreign jurisdictions including, Japan, China, India, Canada and Korea. If issued, and if the appropriate maintenance, renewal, annuity or other governmental fees are paid, we expect that these patents will expire between 2027 and 2030, excluding any additional term for patent term adjustments or patent term extensions in the United States. We note that the patent laws of foreign countries differ from those in United States, and the degree of protection afforded by foreign patents may be different from the protection offered by U.S. patents.

 

Further, we seek trademark protection in the United States and internationally where available and when appropriate. We have registered our ACELRX mark in Class 5, “Pharmaceutical preparations for treating pain; pharmaceutical preparations for treating anxiety,” and Class 10, “Drug delivery systems; medical device, namely, a mechanical and electronic device used to administer medications, perform timed medication delivery, and to provide secure access to and delivery of medications,” in the United States.

 

Our ACELRX mark is also registered in the European Community, Canada, and India. We have also registered the mark ACCELERATE. INNOVATE. ALLEVIATE. in the United States.

Competition

 

Our industry is highly competitive and subject to rapid and significant technological change. Our potential competitors include large pharmaceutical and biotechnology companies, specialty pharmaceutical and generic drug companies, and medical technology companies. We believe the key competitive factors that will affect the development and commercial success of our product candidates are the safety, efficacy and tolerability profile, the patient and healthcare professional satisfaction with using our product candidates in relation to available alternatives and the reliability, convenience of dosing, price and reimbursement of our product candidates.

 

Many of our potential competitors, including many of the organizations named below, have substantially greater financial, technical and human resources than we do and significantly greater experience in the development of product candidates, obtaining FDA and other regulatory approvals of products and the commercialization of those products. Accordingly, our competitors may be more successful than we may be in obtaining FDA approval for drugs and achieving widespread market acceptance. Our competitors’ drugs may be more effective, or may be more effectively marketed and sold, than any drug we may commercialize, which may render our product candidates obsolete or non-competitive before we can recover our losses. We anticipate that we will face intense and increasing competition as new drugs enter the market and advanced technologies become available.

 

Potential Competition for Zalviso

 

We are developing Zalviso for the management of moderate-to-severe acute pain in adult patients during hospitalization. We believe that Zalviso would compete with a number of opioid-based and non-opioid based treatment options that are currently available, as well as some products that are in development. These products can be grouped into three classes – PCA-based systems, most commonly using an opioid as the pain control agent; non PCA-based systems that require nurse delivery of oral or parenteral opioids; and other non-opioid based treatment modalities. Due to the difficulty of managing moderate-to-severe pain, healthcare professionals will often use a combination of PCA opioids, parenteral or oral opioids and non-opioid based treatments to manage pain.

 

The primary competition for Zalviso is the IV PCA pump, which is widely used in the management of moderate-to-severe acute pain in the hospital setting. Leading manufacturers of IV PCA pumps include Hospira Inc. (recently acquired by Pfizer), CareFusion Corporation (recently purchased by Becton Dickinson & Co.), Baxter International Inc., Curlin Medical, Inc. and Smiths Medical. The most common opioids used to treat moderate-to-severe acute pain are morphine, hydromorphone and fentanyl, all of which are available as generics both from generic product manufacturers as well as from compounding pharmacies. In addition, branded manufacturers (e.g., Hospira, Inc.) sell pre-filled glass syringes of morphine to fit their IV PCA pump systems.

 

Also available on the market is the Avancen Medication on Demand, or MOD, Oral PCA Device developed by Avancen MOD Corporation. Oral opioids and other agents can be used in this system. In addition, oral and parenteral opioids administered by the nurse are used to manage moderate-to-severe acute pain in the hospital, available both as branded and generic products. These oral opioids, as well as IV PCA opioids, are often used as part of a multi-modal analgesia approach, which might include, in addition to the opioid, NSAIDs, acetaminophen, gabapentanoids and other pain management modalities, as well as local anesthetic blocks to provide temporary blockage of the pain signal, either as a wound infiltration agent or as a nerve block. These local anesthetic agents such as bupivacaine can also utilize controlled-release formulations such as Pacira’s EXPAREL In addition, Halyard Health, Inc. has developed a medical device, the ON-Q* Pain Relief System, which is a non-narcotic elastomeric pump that automatically and continuously delivers a regulated flow of local anesthetic to a patient’s surgical site or in close proximity to nerves, providing targeted pain relief for up to five days.

 

Additional potential competitors for Zalviso include products in development, including the fentanyl iontophoretic transdermal system, IONSYS, originally developed by ALZA Corporation and Ortho-McNeil Pharmaceutical, Inc., both Johnson & Johnson subsidiaries, and now under development by The Medicines Company. The Medicines Company has reported that IONSYS has a PDUFA date of April 30, 2015. If approved on this date, IONSYS may be marketed prior to the potential approval of Zalviso which may provide a first-to-market advantage for IONSYS. Cara Therapeutics is developing a kappa opioid agonist, CR845, as an IV agent for the management of post-operative moderate-to-severe pain. Trevena is developing TRV130, an intravenous G protein biased ligand that targets the mu opioid receptor for the treatment of moderate-to-severe acute pain where intravenous therapy is preferred, with a clinical development focus in acute postoperative pain. In January 2015, Trevena initiated a Phase 2b clinical study of TRV130. Recro Pharma is developing an intranasal form of dexmedetomidine as a potential agent for the management of post-operative pain. Finally, Innocoll is developing XARACOLL, a controlled-release resorbable implant containing bupivacaine, and Durect has been developing POSIDUR, a controlled-release bupivacaine product candidate utilizing Durect’s SABER technology.

 

 

Potential Competition for ARX-04

 

Within the civilian environment, there are a wide variety of approved injectable and oral opioid products to treat moderate-to-severe acute pain, including IV opioids such as morphine, fentanyl, hydromorphone and meperidine or oral opioids such as oxycodone and hydrocodone. More specifically, competitors for ARX-04 in the emergency department are likely to include generic injectable intravenous opioids such as morphine, hydromorphone and fentanyl. In this environment, ARX-04 may also compete with other branded non-invasive products such as Eagalet’s SPRIX, Hospira’s DYLOJECT, Pfizers OXECTA, Depomed’s NUCYNTA, BMS’s COMBUNOX, Purdue’s OXYFAST, Endo’s OPANA, or generic oral opioids which have moderate-to-severe acute pain labeling. In the short-stay or ambulatory surgery segment, ARX-04 will likely compete with these products in addition to generic injectable local anesthetics such as bupivacaine, or branded formulations thereof, including Pacira’s EXPAREL. Within the military environment, and in certain civilian settings, ARX-04 competitors may also include intramuscular morphine injections which are marketed by a variety of generic manufacturers.

Potential Competition for ARX-02

 

We are developing ARX-02, the Sufentanil Sublingual Tablet BTP Management System, for the treatment of breakthrough pain in opioid tolerant patients, with an initial indication in cancer patients. The market for opioids for treatment of cancer breakthrough pain is large and competitive; however, currently there are no sufentanil products approved by the FDA for this indication. Our potential competitors for ARX-02 include products approved in the United States for cancer breakthrough pain, including: ACTIQ and FENTORA, currently manufactured by Teva Pharmaceuticals; Onsolis, currently manufactured by BioDelivery Sciences International, Inc.; Abstral, currently manufactured by ProStrakan Group plc; Lazanda, currently manufactured by Depomed, Inc.; Subsys, currently manufactured by Insys Therapeutics, Inc., as well as products approved in Europe, including Instanyl, currently manufactured by Takeda Pharmaceuticals International GmbH. The active ingredient in all approved products for cancer breakthrough pain is fentanyl. Additional potential competitors for ARX-02 include products in late stage development for cancer breakthrough pain, such as: Fentanyl TAIFUN, currently manufactured by Akela Pharma, Inc.

 

Potential Competition for ARX-03

 

We are developing ARX-03, the Sufentanil/Triazolam Sublingual Tablet, for use in diagnostic or therapeutic painful procedures of short duration in a physician’s office. For these procedures, many practitioners rely primarily on local anesthetics injected to the procedural area to reduce the pain of the procedure, and do not use IV sedatives to manage the anxiety of patients because of the cost of having additional trained staff to monitor the patients. Currently, we are not aware of any products on the market which combine an opioid with a benzodiazepine in a single dosage form to manage the anxiety and pain of procedures in a physician’s office. We are not aware of any approved or development stage non-IV sedative/analgesic products that would present competition to ARX-03. In the future, there may be products developed or approved for this market which could directly compete with ARX-03.

 

Pharmaceutical Manufacturing and Supply

 

We currently rely on contract manufacturers to produce sufentanil sublingual tablets and sufentanil/triazolam sublingual tablets for our clinical trials under current Good Manufacturing Practices, or cGMP, with oversight by our internal managers. Equipment specific to the pharmaceutical manufacturing process was purchased and customized by us and is currently owned by us. We plan to continue to rely on contract manufacturers and, potentially, collaboration partners to manufacture commercial quantities of our product candidates if and when approved for marketing by the FDA. We currently rely on a single manufacturer for the preclinical and clinical supplies of our drug product for each of our product candidates and do not currently have agreements in place for redundant supply or a second source for any of our product candidates. We have identified other manufacturers that could satisfy our commercial supply and packaging requirements and we continue to evaluate those manufacturers.

 

In January 2013, we entered into a Manufacturing Services Agreement, or the Services Agreement, with Patheon Pharmaceuticals, Inc., or Patheon, relating to the manufacture of sufentanil sublingual tablets for use with the Zalviso device. Under the terms of the Services Agreement, Patheon has agreed to manufacture, supply, and provide certain validation and stability services with respect to Zalviso for sale in the United States, Canada, Mexico and other countries, subject to agreement by the parties to any additional fees for such other countries. The term of the Services Agreement extends until December 31, 2017, or the Initial Term, and will automatically renew thereafter for periods of two years, unless terminated by either party upon eighteen months’ prior written notice; provided, however, that the Services Agreement may not be terminated without cause prior to the end of the Initial Term. In addition, we entered into a related Amended and Restated Capital Expenditure and Equipment Agreement, or the Amended Capital Agreement, related to clinical and commercial production of our product candidates. Under the terms of the Amended Capital Agreement, we have made, and may make certain future modifications to Patheon’s Cincinnati facility.

 

Device Manufacturing and Supply

 

The device components of Zalviso are manufactured by contract manufacturers, component fabricators and secondary service providers. Suppliers of components, subassemblies and other materials are located in Korea, Japan, Germany, China, Taiwan, Canada and the United States. All contract manufacturers and component suppliers have been selected for their specific competencies in the manufacturing processes and materials that make up Zalviso. FDA regulations require that materials be produced under cGMPs or Quality System Regulation, or QSR. We outsource injection molding of all the plastic parts for the cartridge and device and product sub-assemblies; tablet cartridge filling and packaging; and assembly, packaging and labeling of the dispenser and controller.

ARX-02 is manufactured by contract manufacturers, component fabricators and secondary service providers. Suppliers of components, subassemblies and other materials are located in Korea, Japan, China, Taiwan, Canada and the United States. All contract manufacturers and component suppliers have been selected for their specific competencies in the manufacturing processes and materials that make up ARX-02. FDA regulations require that materials be produced under cGMPs or QSR, as required for the respective unit operation within the manufacturing process. We outsource injection molding of all the plastic parts for the SDA and MSD and product sub-assemblies; and filling, packaging and labeling of SDAs.

 

ARX-03 and ARX-04 both utilize SDAs in the delivery of the sufentanil/triazolam sublingual tablets and sufentanil sublingual tablets. FDA regulations require that materials be produced under cGMPs or QSR, as required for the respective unit operation within the manufacturing process. We outsource injection molding of all the plastic parts for the SDA, and product sub-assemblies; and filling, packaging and labeling of SDAs.

 

Government Regulation

 

Government authorities in the United States at the federal, state and local level, and in other countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing, export and import of products such as those we are developing. Our product candidates must be approved by the FDA through the NDA process before they may legally be marketed in the United States.

 

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and regulations. The process of obtaining regulatory approvals and complying with applicable laws and regulations requires the expenditure of substantial time and financial resources. Failure to comply at any time during the product development and approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. The process required by the FDA before a drug product may be marketed in the United States generally involves the following:

 

 

completion of non-clinical laboratory tests, animal trials and formulation studies according to Good Laboratory Practices regulations;

 

 

submission to the FDA of an investigational new drug, or IND, application which must become effective before human clinical trials may begin;

 

 

performance of adequate and well-controlled human clinical trials according to Good Clinical Practices, or GCP, to establish the clinical safety and efficacy of the proposed drug product for its intended use;

 

 

 

submission to the FDA of an NDA for a new drug product;

 

 

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug product and the drug substance(s) are produced to assess compliance with cGMP;

 

 

payment of user and facility fees; and

 

 

FDA review and approval of the NDA.

 

The testing and approval process requires substantial time, effort and financial resources and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, if at all.

 

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

 

 

Phase 1. The product is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

 

 

Phase 2. Involves trials in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted conditions and to determine dosage tolerance and optimal dosage and schedule.

 

 

Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical safety and efficacy in an expanded patient population at geographically dispersed clinical trial sites. These trials are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labeling.

 

 
27

 

 

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events. The FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an institutional review board, or IRB, can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug or biological product has been associated with unexpected serious harm to patients.

 

Concurrent with clinical trials, companies usually complete additional animal trials and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP and QSR for medical devices requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

 

Our product candidates, Zalviso, ARX-02, ARX-03 and ARX-04, are regulated under IND applications for clinical development and in the case of Zalviso, all device related information is filed under the Chemistry, Manufacturing and Controls Section, or CMC, of an IND.

 

The results of product development, preclinical trials and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on our drug products, proposed labeling and other relevant information, will be submitted to the FDA as part of an NDA for a new drug product, requesting approval to market the product in the United States. The submission of an NDA is subject to the payment of a substantial user fee; a waiver of such fee may be obtained under certain limited circumstances. During its review of an NDA, FDA may inspect our manufacturers for GMP and QSR compliance, and our pivotal clinical trial sites for GCP compliance.

 

In addition, under the Pediatric Research Equity Act, an NDA or supplement to an NDA must contain data to assess the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers.

 

The approval process is lengthy and difficult and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Even if such data and information is submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA issues a Complete Response Letter at the conclusion of its review if the NDA is not yet deemed ready for approval. A Complete Response Letter generally outlines the deficiencies in the submission and may require substantial additional testing or information for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included.  

 

If one or more of our product candidates receive regulatory approval, the approval may be limited to specific conditions and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Our product candidates, if approved, will also require Risk Evaluations and Mitigation Strategies, or REMS, which can include a medication guide, patient package insert, a communication plan, elements to assure safe use and implementation system, and must include a timetable for assessment of the REMS. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized. In addition, the FDA may require post-approval testing which involves clinical trials designed to further assess a drug product’s safety and effectiveness after the NDA.

 

Post-Approval Requirements

 

Any drug products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated clinical safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements. Phase 4 clinical trials are conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic indication or when otherwise requested by the FDA in the form of postmarketing requirements or commitments. Failure to promptly conduct any required Phase 4 clinical trials could result in withdrawal of NDA approval. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. Drug products may be promoted only for the approved indications and in accordance with the provisions of the approved label. Further, manufacturers of drug products must continue to comply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

 

 
28

 

 

Drug product manufacturers and other entities involved in the manufacturing and distribution of approved drug products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, packaging, labeling, storage and shipment of the drug product. Manufacturers must establish validated systems to ensure that products meet specifications and regulatory standards, and test each product batch or lot prior to its release. In the case of Zalviso, the device component must comply with FDA’s Quality Systems Regulation.

 

We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products. Future FDA and state inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt production or distribution or may require substantial resources to correct.

 

The FDA may withdraw a product approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatory requirements may result in administrative or judicial actions, such as fines, warning letters, holds on clinical trials, product recalls or seizures, product detention or refusal to permit the import or export of products, refusal to approve pending applications or supplements, restrictions on marketing or manufacturing, injunctions or civil or criminal penalties.

 

Foreign Regulation

 

In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our products to the extent we choose to sell any products outside of the United States. In October 2012, we received notice from the European Medicines Agency, or EMA, that Zalviso was eligible for centralized marketing authorization application, or MAA, in the European Union, or EU. This regulatory procedure, reserved for novel products, biotechnology products and new chemical entities, allows for commercialization across 31 EU and EFTA countries based on approval by EMA. In July 2014, Grünenthal filed an MAA with the EMA under the centralized procedure in the EU for Zalviso for the management of moderate-to-severe acute pain in adult patients in a medically-supervised environment. In addition, since Zalviso is considered a drug-device combination product candidate, conformance to the European Medical Device Directive required Conformite Europeenne, or CE, Mark approval for the Zalviso device to enable commercialization in the EU. In December 2014, we announced that we had received CE Marking for Zalviso. Outside of Europe, the requirements and approval process vary from country to country and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

 

Controlled Substances Regulations

 

Sufentanil, a Schedule II controlled substance, is the active pharmaceutical ingredient in Zalviso, ARX-02, ARX-03 and ARX-04. Triazolam, a Schedule IV controlled substance, is also an active pharmaceutical ingredient in ARX-03. Controlled substances are governed by the Drug Enforcement Administration, or DEA, of the U.S. Department of Justice. The handling of controlled substances and/or drug product by us, our contract manufacturers, analytical laboratories, packagers and distributors, are regulated by the Controlled Substances Act and regulations thereunder.

 

The Drug Supply Chain Security Act imposes new obligations on manufacturers of pharmaceutical products, among others, related to product tracking and tracing. Among the requirements are that manufacturers will be required to provide certain information regarding the drug product to individuals and entities to which product ownership is transferred, label drug product with a product identifier, and keep certain records regarding the drug product. Further, manufacturers will have drug product investigation, quarantine, disposition, and notification responsibilities related to counterfeit, diverted, stolen, and intentionally adulterated products, as well as products that are the subject of fraudulent transactions or which are otherwise unfit for distribution such that they would be reasonably likely to result in serious health consequences or death.

 

 
29

 

 

Unforeseen delays to the drug substance and drug product manufacture and supply chain may occur due to delays, errors or other unforeseen problems with the permitting and quota process. Also, any one of our suppliers, contract manufacturers, laboratories, packagers and/or distributors could be the subject of DEA violations and enforcement could lead to delays or even loss of DEA license by the contractors.

 

Federal and State Fraud and Abuse and Data Privacy and Security and Transparency Laws and Regulations

 

In addition to FDA restrictions on marketing of pharmaceutical products, federal and state healthcare laws restrict certain business practices in the pharmaceutical industry. These laws include, but are not limited to, anti-kickback, false claims, data privacy and security, and transparency statutes and regulations.

 

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration, directly or indirectly, to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any good, facility, item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of cash, waivers of payment, ownership interests and providing anything at less than its fair market value. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers and formulary managers on the other. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and our practices may not in all cases meet all of the criteria for a statutory exception or safe harbor protection. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. A claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act (discussed below).

 

The federal false claims laws prohibit, among other things, any person or entity from knowingly presenting, or causing to be presented, a false or fraudulent claim for payment or approval to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. Pharmaceutical and other healthcare companies have been prosecuted under these laws for, among other things, allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of the product for unapproved, and thus non-reimbursable, uses. Further, civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.

 

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates—independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

 

Additionally, the federal Physician Payments Sunshine Act within the PPACA, and its implementing regulations, require that certain manufacturers of drugs, devices, biologicals and medical supplies for which federal healthcare program payment is available to report information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate
family members.

 

Also, many states have similar healthcare statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer. FDA and some states require the posting of information relating to clinical studies. In addition, California requires pharmaceutical companies to implement a comprehensive compliance program that includes a limit on expenditures for, or payments to, individual medical or health professionals. If our operations are found to be in violation of any of the health regulatory laws described above or any other laws that apply to us, we may be subject to penalties, including potentially significant criminal, civil and/or administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion of products from reimbursement under government programs, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. To the extent that any of our products will be sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.

Pharmaceutical Coverage, Pricing and Reimbursement

 

In both domestic and foreign markets, our sales of any approved products will depend in part on the availability of coverage and adequate reimbursement from third-party payers. Third-party payers include government health administrative authorities, managed care providers, private health insurers and other organizations. Sales of our products will depend substantially, both domestically and abroad, on the extent to which the costs of our products will be paid by third-party payers. These third-party payers are increasingly focused on containing healthcare costs by challenging the price and examining the cost-effectiveness of medical products and services. In addition, significant uncertainty exists as to the coverage and reimbursement status of newly approved healthcare product candidates. Third-party payers may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent or other alternative is available. Because each third-party payer individually approves coverage and reimbursement levels, obtaining coverage and adequate reimbursement is a time-consuming, costly and sometimes unpredictable process. We may be required to provide scientific and clinical support for the use of any product to each third-party payer separately with no assurance that approval would be obtained, and we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our products. This process could delay the market acceptance of any product and could have a negative effect on our future revenues and operating results. We cannot be certain that our products and our product candidates will be considered cost-effective. Because coverage and reimbursement determinations are made on a payer-by-payer basis, obtaining acceptable coverage and reimbursement from one payer does not guarantee that we will obtain similar acceptable coverage or reimbursement from another payer. If we are unable to obtain coverage of, and adequate reimbursement and payment levels for, our product candidates from third-party payers, physicians may limit how much or under what circumstances they will prescribe or administer them. This in turn could affect our ability to successfully commercialize our products and impact our profitability, results of operations, financial condition and future success.

 

In addition, in many foreign countries, particularly the countries of the European Union, the pricing of prescription drugs is subject to government control. In some non-U.S. jurisdictions, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the EU provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. We may face competition for our product candidates from lower-priced products in foreign countries that have placed price controls on pharmaceutical products. In addition, there may be importation of foreign products that compete with our own products, which could negatively impact our profitability.

 

Healthcare Reform

 

In the United States and foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system that could affect our future results of operations as we begin to commercialize our products. In particular, there have been and continue to be a number of initiatives at the United States federal and state level that seek to reduce healthcare costs. Government payment for some of the costs of prescription drugs may increase demand for our products for which we receive marketing approval. However, any negotiated prices for our future products will likely be lower than the prices we might otherwise obtain from non-governmental payers. Moreover, private payers often follow federal healthcare coverage policy and payment limitations in setting their own payment rates.

 

Furthermore, political, economic and regulatory influences are subjecting the healthcare industry in the United States to fundamental change. Initiatives to reduce the federal deficit and to reform healthcare delivery are increasing cost-containment efforts. We anticipate that Congress, state legislatures and the private sector will continue to review and assess alternative benefits, controls on healthcare spending through limitations on the growth of private health insurance premiums and Medicare and Medicaid spending, the creation of large insurance purchasing groups, price controls on pharmaceuticals and other fundamental changes to the healthcare delivery system. Any proposed or actual changes could limit or eliminate our spending on development projects and affect our ultimate profitability. In March 2010, PPACA was signed into law. Among other cost containment measures, PPACA established an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents. In the future, there may continue to be additional proposals relating to the reform of the U.S. healthcare system, some of which could further limit the prices we are able to charge for our products, or the amounts of reimbursement available for our products. If future legislation were to impose direct governmental price controls and access restrictions, it could have a significant adverse impact on our business. Managed care organizations, as well as Medicaid and other government agencies, continue to seek price discounts. Some states have implemented, and other states are considering, price controls or patient access constraints under the Medicaid program, and some states are considering price-control regimes that would apply to broader segments of their populations that are not Medicaid-eligible. Due to the volatility in the current economic and market dynamics, we are unable to predict the impact of any unforeseen or unknown legislative, regulatory, payer or policy actions, which may include cost containment and healthcare reform measures. Such policy actions could have a material adverse impact on our profitability.

Research and Development

 

Conducting research and development is central to our business model. We have invested and expect to continue to invest significant time and capital in our research and development operations. Our research and development expenses were $24.5 million, $26.3 million and $24.9 million during the years ended December 31, 2014, 2013 and 2012, respectively. We plan to incur significant expenditures for the foreseeable future as we seek to continue commercial preparations for Zalviso and development of ARX-04, and subsequently advance the development of ARX-02 and ARX-03 contingent upon additional funding or identification of corporate partnership resources.

 

Employees

 

As of December 31, 2014, we employed 50 full-time employees. None of our employees are subject to a collective bargaining agreement. We consider our relationship with our employees to be good.

Item 1A. Risk Factors

 

This Form 10-K contains forward-looking information based on our current expectations. Because our actual results may differ materially from any forward-looking statements made by or on behalf of us, this section includes a discussion of important factors that could affect our actual future results, including, but not limited to, our revenues, expenses, net loss and loss per share. We believe the risks described below are the risks that are material to us as of the date of this Form 10-K. If any of the following risks comes to fruition, our business, financial condition, results of operations and future growth prospects would likely be materially and adversely affected.

 

Risks Related to Clinical Development and Regulatory Approval 

 

We depend substantially on the success of Zalviso, which may not receive regulatory approval or be successfully commercialized.

 

Since our inception in 2005, we have focused primarily on development of our lead product candidate, ZalvisoTM. Zalviso consists of sufentanil sublingual tablets delivered by the Zalviso System, a needle-free, handheld, patient-administered, pain management system (together, “Zalviso”). The success of our business depends primarily upon our ability to develop, receive regulatory approval for and commercialize Zalviso for the management of moderate-to-severe acute pain in adult patients in the hospital setting. We have not marketed, distributed or sold any products to date.

 

Our Phase 3 program for Zalviso consisted of three Phase 3 clinical trials. We reported positive top-line data from each of these trials and submitted a New Drug Application, or NDA, for Zalviso to the U.S. Food and Drug Administration, or FDA, on September 27, 2013, which the FDA then accepted for filing in December 2013. On July 25, 2014, the FDA issued a Complete Response Letter, or CRL, for our NDA for Zalviso. The CRL contains requests for additional information on the Zalviso System to ensure proper use of the device. The requests include submission of data demonstrating a reduction in the incidence of optical system errors, changes to address inadvertent dosing, among other items, and submission of additional data to support the shelf life of the product. In September 2014, we held a teleconference with representatives from the FDA to review our proposed response to the Zalviso CRL. We submitted a Briefing Document to the FDA ahead of the teleconference and received preliminary comments from the FDA on the Briefing Document. During the meeting, we discussed the resubmission of the Zalviso NDA and the steps necessary for the resubmission, including submission of protocols for the bench testing and Human Factors, or HF, studies for their review and comment. In addition, the FDA requested in the minutes of the meeting that we provide a risk assessment that analyzes the risks associated with inadvertent dosing and the rationale that bench testing and HF studies are sufficient to address the specific items included in the CRL. We submitted the protocols and this rationale in the fourth quarter of 2014. In January 2015, we received feedback from the FDA on the protocol and planned analysis of the results of the bench test. No modifications to the conduct of the bench test were necessary; however, in response to the FDA’s request, we refined the planned analysis of the bench test results. In February 2015, we received feedback from the FDA on the HF protocols. In this feedback, the FDA confirmed that the HF studies as proposed were acceptable to evaluate the design changes related to inadvertent dispensing of tablets. In March 2015, we received additional correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. As a result of this most recent FDA communication and the need for clarity with the FDA, resubmission of the NDA for Zalviso is on hold.

 

As noted above, we plan to hold a meeting with the FDA to discuss the recent correspondence. However, there is no guarantee that we will be granted such a meeting with the FDA and, even if granted, that it will occur on a timely basis. In addition, even if we are able to hold a meeting with the FDA, there is no guarantee that we will achieve clarity with respect to the FDA’s March 2015 request for additional clinical data, or that we will be able to define the nature and scope of an additional clinical study to meet these requests. There is no guarantee that additional work we perform related to Zalviso, including an additional human clinical trial, will be supportive of an NDA resubmission, nor does it guarantee we will be successful in obtaining FDA approval of Zalviso in a timely fashion, if at all. At any future point in time, the FDA could require us to complete further clinical, Human Factors, pharmaceutical, reprocessing or other studies, which could delay or preclude any approval of the NDA and would require us to obtain significant additional funding. There is no guarantee such funding would be available to us on favorable terms, if at all.

 

Our proposed trade name of Zalviso has been approved by the FDA, which must approve all drug trade names to avoid medication errors and misbranding. However, the FDA may withdraw this approval in which case any brand recognition or goodwill that we establish with the name Zalviso prior to commercialization may be worthless.

 

Any delay in approval by the FDA of the Zalviso NDA may negatively impact our stock price and harm our business operations. Any delay in obtaining, or inability to obtain, regulatory approval would prevent us from commercializing Zalviso in the United States, generating revenues and achieving profitability. If any of these events occur, we may be forced to delay or abandon our development efforts for Zalviso, which would have a material adverse effect on our business and could potentially cause us to cease operations.

 

Although we have received CE Mark approval permitting the commercial use of the Zalviso device in the European Union, Grünenthal may never achieve regulatory approval for Zalviso in their licensed territories, including the EU and Australia, in which case, we would not receive development or sales milestones, or product royalties, which could have a material adverse effect on our business.

 

 
33

 

 

Positive clinical results obtained to date for our product candidates may be disputed in FDA review, do not guarantee regulatory approval and may not be obtained from future clinical trials.

 

We have reported positive top-line data from each of our three Zalviso Phase 3 clinical trials, as well as our Phase 2 clinical trial for ARX-04. However, even if we believe that the data from clinical trials is positive, the FDA could analyze our data using alternative strategies and determine that the data from our trials was negative or inconclusive. Negative or inconclusive results of a clinical trial could cause the FDA to require us to repeat the trial or conduct additional clinical trials prior to obtaining approval for commercialization, and there is no guarantee that additional trials would achieve positive results. Any such determination by the FDA would delay the timing of our commercialization plan for Zalviso, or further development of our other product candidates, and adversely affect our business operations. For example, although we had achieved the primary endpoints in each of our three Phase 3 clinical trials for Zalviso, which were included in our NDA filed in 2013, in March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures.

 

Delays in clinical trials are common and have many causes, and any delay could result in increased costs to us and jeopardize or delay our ability to obtain regulatory approval and commence product sales.

 

We have experienced and may in the future experience delays in clinical trials of our product candidates. While we have completed pre-commercial trials for Zalviso, and the Phase 2 clinical trial for ARX-04, current and potential future clinical trials, such as with the ARX-04 Phase 3 clinical program, may not begin on time, have an effective design, enroll a sufficient number of patients or be completed on schedule, if at all. For example, in June 2014, we completed a pharmacokinetic study in support of the ARX-04 development program. In this study of healthy volunteers, it was shown that two sublingual administrations of a Zalviso 15mcg sufentanil sublingual tablet dosed 20 minutes apart were equivalent to one sublingual administration of an ARX-04 30mcg sufentanil sublingual tablet. Based on the results of this study, we have proposed the inclusion of approximately 300 patients from the Zalviso clinical program in the ARX-04 safety database to the FDA and we have designed the two Phase 3 ARX-04 trials accordingly. The ARX-04 safety database required by the FDA is 500 patients. We have confirmation from FDA that some of the Zalviso patients can be included in the overall ARX-04 safety database; however, further discussion is needed to determine the exact number of such patients that can be used towards achieving the 500 patient minimum total safety exposure number required for ARX-04. Based on an ongoing pharmacokinetic analysis, we may need to increase enrollment in our planned Phase 3 clinical trial program to meet the FDA’s requested exposure requirements to ARX-04, which could delay the Phase 3 clinical program and increase our clinical trial expenses.

 

Our clinical trials for any of our product candidates could be delayed for a variety of reasons, including:

 

 

inability to raise funding necessary to initiate or continue a trial;

 

 

delays in finalizing, or inability to complete, the contract negotiations with DoD for ARX-04 funding;

 

 

delays in obtaining regulatory approval to commence a trial;

 

 

delays in reaching agreement with the FDA on final trial design;

 

 

imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;

 

 

delays in reaching agreement on acceptable terms with prospective contract research organizations, or CROs, and clinical trial sites;

 

 

delays in obtaining required institutional review board approval at each site;

 

 

delays in recruiting suitable patients to participate in a trial;

 

 

delays in the testing, validation, manufacturing and delivery of the device components of our product candidates;

 

 

 

delays in having patients complete participation in a trial or return for post-treatment follow-up;

 

 

clinical sites dropping out of a trial to the detriment of enrollment or being delayed in entering data to allow for clinical trial database closure;

 

 

time required to add new clinical sites; or

 

 

delays by our contract manufacturers to produce and deliver sufficient supply of clinical trial materials.

 

If any future clinical trials are delayed for any of the above reasons, our development costs may increase, our approval process could be delayed and our ability to commercialize and commence sales of our product candidates could be materially harmed, which could have a material adverse effect on our business.

 

We have never responded to a Complete Response Letter nor resubmitted an NDA. Activities that we undertake to address issues raised in the CRL may be deemed insufficient by the FDA.

  

 
34

 

 

We recently completed bench testing and additional Human Factors studies that we believed addressed certain items contained in the CRL. However, before the results from these studies were submitted as a part of the proposed NDA resubmission, the FDA, in March 2015, notified us of the need for an additional clinical study prior to the resubmission of the Zalviso NDA.

 

In March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. As a result of this most recent correspondence, we may require additional funding in order to complete the additional clinical study requested by the FDA for Zalviso. Even if we have appropriate resources to conduct an additional clinical study, there is no guarantee that the study results would address the issues raised by the FDA. We may be unable to obtain additional funding on favorable terms, if at all. Any delay in obtaining, or inability to obtain, regulatory approval would prevent us from commercializing Zalviso in the United States, generating revenues and achieving profitability. If any of these events occur, we may be forced to delay or abandon our development efforts for Zalviso, which would have a material adverse effect on our business and could potentially cause us to cease operations.

 

If we are able to resubmit an NDA for Zalviso with new clinical data, there is no guarantee that such data will be deemed sufficient by the FDA. In addition, the FDA may evaluate the recent HF studies and bench testing and may have concerns or issues with those protocols and/or their results. While we designed the protocols for bench testing and the Human Factors studies to address the issues raised in the CRL, there is no guarantee that the FDA will deem such protocols and results sufficient to address those issues when they are formally reviewed as a part of an NDA resubmission.

 

Lastly, even if we believe that the test results from our bench testing and Human Factors studies are positive, and we are able to conduct and achieve positive results from the additional clinical trial the FDA has requested, the FDA may hold a different opinion and deem the results insufficient. The FDA may provide review commentary at any time during the resubmission and review process which could adversely affect or even prevent the approval of Zalviso, which would adversely affect our business. We may not be able to identify appropriate remediations to issues that the FDA may raise, and we may not have sufficient time nor financial resources to conduct future activities to remediate raised issues.

 

Our product candidates may cause adverse effects or have other properties that could delay or prevent their regulatory approval or limit the scope of any approved label or market acceptance.

 

Adverse events, or AEs, caused by our product candidates could cause us, other reviewing entities, clinical trial sites or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of regulatory approval. In our Phase 3 active comparator clinical trial (IAP309), 7.9% of Zalviso-treated patients dropped out of the trial prematurely due to an AE, and we observed one serious adverse event, or SAE, that was assessed as possibly or probably related to Zalviso. In our Phase 3, double-blind, placebo-controlled, abdominal surgery trial (IAP310), adverse events reported in the trial were generally mild or moderate in nature and similar in both placebo and treatment groups. In addition, one patient in the trial, who was in the sufentanil sublingual tablet group, experienced an SAE, which was determined to be unrelated to the trial drug. In our Phase 3, double-blind, placebo-controlled, orthopedic surgery trial (IAP311), treatment-emergent adverse events were generally mild-to-moderate in nature and similar for the majority of adverse events between sufentanil sublingual tablet- and placebo-treated patients. Two patients (one each in the sufentanil sublingual tablet group and placebo group) experienced a serious adverse event considered possibly or probably related to the trial drug by the investigator.

 

In our Phase 2 ARX-04 trial, two serious adverse events (SAEs), both in the 20 mcg-dose group, occurred one week after the study (surgical infections) and were deemed unrelated to study drug. All but two adverse events reported in the study were mild-to-moderate in nature with 58 patients (58%) reporting a total of 135 adverse events. The most frequently reported adverse events for all patients were nausea (30%), vomiting (17%), dizziness (14%) and somnolence (11%). Two patients discontinued treatment, one unrelated to study drug (anxiety/chest pain) and the other probably related to study drug (somnolence/respiratory depression); however, both patients recovered without medical intervention.  

 

 
35

 

 

Phase 2 clinical trials conducted by us with our Zalviso, ARX-02, ARX-03 and ARX-04 product candidates have to date generated some AEs, but no SAEs, related to the trial drug.

 

Further, if any of our future products, including Zalviso, cause serious or unexpected side effects after receiving marketing approval, a number of potentially significant negative consequences could result, including:

 

 

regulatory authorities may withdraw their approval of the product or impose restrictions on its distribution in the form of a modified Risk Evaluation and Mitigation Strategy, or REMS;

 

 

regulatory authorities may require the addition of labeling statements, such as warnings or contraindications;

 

 

we may be required to change the way the product is administered or conduct additional clinical trials;

 

 

we could be sued and held liable for harm caused to patients; or

 

 

our reputation may suffer.

 

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing our product candidates.

 

Additional time may be required to obtain regulatory approval for Zalviso because it is a drug/device combination. 

 

Zalviso is a combination product candidate with both drug and device components. Zalviso is viewed as a combination product by the FDA, and both drug and device components were required for review as part of our NDA submission. There are very few examples of the FDA approval process for drug/device combination products such as Zalviso. As a result, we have in the past, and may in the future, experience delays in the development and commercialization of Zalviso due to regulatory uncertainties in the product development and approval process, in particular as it relates to a drug/device combination product approval under an NDA. For example, the Zalviso CRL received from the FDA in July 2014 contains requests for additional information on the Zalviso System to ensure proper use of the device. The requests include submission of data demonstrating a reduction in the incidence of optical system errors, changes to address inadvertent dosing, among other items, and submission of additional data to support the shelf life of the product. Furthermore, in March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. We may be unable to come to an agreement with the FDA on the need, design or objectives of the requested clinical study. Even if we come to an agreement on the design and objectives of the clinical study and are able to complete the clinical study, the FDA may deem the results of the clinical study, as well as bench testing and/or the Human Factors studies inadequate, which could delay or preclude any approval of Zalviso.

 

We cannot predict when we will obtain regulatory approval to commercialize any of our product candidates, if at all, and we cannot, therefore, predict the timing of any future revenue.

 

We cannot commercialize any of our product candidates, including Zalviso, until the appropriate regulatory authorities, such as the FDA or the European Medicines Agency, or EMA, have reviewed and approved the product candidate. The regulatory agencies may not complete their review processes in a timely manner, or we may be unable to obtain regulatory approval for our product candidates. We received a CRL for Zalviso on July 25, 2014, which contains requests for additional information on the Zalviso System and requires us to complete additional bench testing and Human Factors studies. In the CRL, the FDA acknowledged that it had not reviewed several of the amendments to the NDA we submitted to the FDA before the CRL was issued. In addition, in March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. Additional delays may result if any of our product candidates is taken before an FDA Advisory Committee which may recommend restrictions on approval or recommend non-approval. In addition, we may experience delays or rejections based upon additional government regulation from future legislation or administrative action, or changes in regulatory agency policy during the period of product development, clinical trials and the review process.

 

The FDA and other foreign regulatory agencies, such as the EMA, can delay, limit or deny marketing approval for many reasons, including:

 

 

a product candidate may not be considered safe or effective;

 

 

the manufacturing processes or facilities we have selected may not meet the applicable requirements; and

 

 

changes in their approval policies or adoption of new regulations may require additional work on our part.

 

 Part of the regulatory approval process includes compliance inspections of manufacturing facilities to ensure adherence to applicable regulations and guidelines. The regulatory agency may delay, limit or deny marketing approval of our product candidates as a result of such inspections. In June 2014, the FDA completed an inspection at our corporate offices. We received a single observation on a Form 483 as a result of the inspection. Although we believe we have adequately addressed this observation in a revised standard operating procedure, we, our contract manufacturers, and their vendors are all subject to preapproval inspections at any time. In addition, in January 2015, the EMA conducted a pre-approval inspection of our Zalviso contract manufacturer’s manufacturing and packaging site, the formal results of which we have not yet received. The results of these inspections could impact our ability to obtain FDA or EMA approval for Zalviso, and, if approved, our ability to launch and successfully commercialize Zalviso.

 

 
36

 

 

Any delay in, or failure to receive or maintain, approval for any of our product candidates could prevent us from generating meaningful revenues or achieving profitability. Our product candidates may not be approved even if they achieve their endpoints in clinical trials. Regulatory agencies, including the FDA, or their advisors may disagree with our trial design and our interpretations of data from preclinical studies and clinical trials. Regulatory agencies may change requirements for approval even after a clinical trial design has been approved. The FDA exercises significant discretion over the regulation of combination products, including the discretion to require separate marketing applications for the drug and device components in a combination product. To date, our product candidates are being regulated as drug products under the NDA process administered by the FDA. The FDA could in the future require additional regulation of our product candidates under the medical device provisions of the FDCA. Our systems are designed to comply with the Quality Systems Regulation, or QSR, which sets forth the FDA’s current good manufacturing practice, or cGMP, requirements for medical devices, and other applicable government regulations and corresponding foreign standards for drug cGMPs. If we fail to comply with these regulations, it could have a material adverse effect on our business and financial condition.

 

Regulatory agencies also may approve a product candidate for fewer or more limited indications than requested or may grant approval subject to the performance of post-marketing trials. In addition, regulatory agencies may not approve the labeling claims that are necessary or desirable for the successful commercialization of our product candidates. For example, we intend to resubmit our NDA seeking approval of Zalviso for the management of moderate-to-severe acute pain in adult patients in the hospital setting; however, our clinical trial data was generated exclusively from the post-operative segment of this population, and the FDA may restrict any approval to post-operative patients only, which would reduce our commercial opportunity.

 

The process for obtaining approval of an NDA is time consuming, subject to unanticipated delays and costs, and requires the commitment of substantial resources. 

 

If the FDA determines that any of the clinical work submitted, including the clinical trials, Human Factors studies and bench testing submitted for a product candidate in support of an NDA were not conducted in full compliance with the applicable protocols for these trials, studies and testing as well as with applicable regulations and standards, or if the FDA does not agree with our interpretation of the results of such trials, studies and testing, the FDA may reject the data and results. The FDA may audit some of our clinical trial sites to determine the integrity of our clinical data. The FDA may audit some of our Human Factors study sites to determine the integrity of our data and may audit the data and results of bench testing. Any rejection of any of our data would negatively impact our ability to obtain marketing authorization for a product candidate and would have a material adverse effect on our business and financial condition. In addition, an NDA may not be approved, or approval may be delayed, as a result of changes in FDA policies for drug approval during the review period. For example, although many products have been approved by the FDA in recent years under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, or FDCA, objections have been raised to the FDA’s interpretation of Section 505(b)(2). If challenges to the FDA’s interpretation of Section 505(b)(2) are successful, the FDA may be required to change its interpretation, which could delay or prevent the approval of such an NDA. Any significant delay in the acceptance, review or approval of an NDA that we have submitted would have a material adverse effect on our business and financial condition and would require us to obtain significant additional funding.

 

Even if we obtain regulatory approval for Zalviso and our other product candidates, we and our collaborators face extensive regulatory requirements and our products may face future development and regulatory difficulties.

 

Even if we obtain regulatory approval in the United States, the FDA may impose significant restrictions on the indicated uses or marketing of our product candidates, or impose ongoing requirements for potentially costly post-approval trials or post-market surveillance. Additionally, the labeling ultimately approved for Zalviso and our other product candidates, if approved, will likely include restrictions on use due to the opioid nature of sufentanil.

 

Zalviso and our other product candidates, if approved in the future, will also be subject to ongoing FDA requirements governing the labeling, packaging, storage, distribution, safety surveillance, advertising, promotion, record-keeping and reporting of safety and other post-market information. The holder of an approved NDA is obligated to monitor and report AEs and any failure of a product to meet the specifications in the NDA. The holder of an approved NDA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws.

 

We must also register and obtain various state prescription drug distribution licenses and controlled substance permits, and any delay or failure to obtain or maintain these licenses or permits may limit our market and materially impact our business. In addition, manufacturers of drug products and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMPs and adherence to commitments made in the NDA. If we, or a regulatory agency, discover previously unknown problems with a product, such as AEs of unanticipated severity or frequency, or problems with the facilities where the product is manufactured, a regulatory agency may impose restrictions relative to that product or the manufacturing facilities, including requiring recall or withdrawal of the product from the market or suspension of manufacturing.

  

 
37

 

 

If we fail to comply with applicable regulatory requirements following approval of our product candidates, a regulatory agency may:

 

 

issue a warning letter asserting that we are in violation of the law;

 

 

seek an injunction or impose civil or criminal penalties or monetary fines;

 

 

suspend or withdraw regulatory approval;

 

 

suspend any ongoing clinical trials;

 

 

refuse to approve a pending NDA or supplements to an NDA submitted by us;

 

 

seize product; or

 

 

refuse to allow us to enter into supply contracts, including government contracts.

 

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize any future approved products and generate revenues.

 

Even if we obtain FDA approval for Zalviso or any of our product candidates in the United States, we may never obtain approval for or commercialize our products outside of the United States, which would limit our ability to realize their full market potential.

 

In order to market any products outside of the United States, we or our collaborators, including Grünenthal in Europe, must establish and comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy. For example, in October 2012, we received notice from the EMA that Zalviso was eligible for centralized European review, and in July 2014, Grünenthal filed a Marketing Authorization Application, or MAA, for Zalviso under the centralized procedure in the EU. In the fourth quarter of 2014, Grünenthal received 120-day questions from the EMA per the EMA’s standard regulatory review process. We have been working with Grünenthal towards the submission of the response to the Day 120 questions. Grünenthal is currently working to complete the response and submit it to the EMA by the end of March 2015. As noted elsewhere, in March 2015, we received correspondence from the FDA stating that an additional clinical study is needed for Zalviso in order to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We do not know what impact, if any, this may have on the EMA’s regulatory review process of the Zalviso MAA. The EMA may at anytime during its review process find issues with the MAA, and may require additional activities and data, including additional clinical trials, in order to support its review of the Zalviso MAA. Outside of Europe, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approval could result in difficulties and costs for us and require additional non-clinical trials or clinical trials, which could be costly and time consuming. Regulatory requirements can vary widely from country-to-country and could delay or prevent the introduction of our products in those countries. Our current clinical trial data may not be sufficient to support marketing approval in all territories. In addition, we lack the personnel, expertise and capabilities to gain regulatory approval of our product candidates on a global basis without a collaboration partner. If Zalviso is approved for sale in Europe, we will rely on Grünenthal to commercialize it. While Grünenthal does have products approved in international markets, we do not have any product candidates approved for sales in any jurisdiction, including international markets, and we do not have experience in obtaining regulatory approval in international markets. Grünenthal’s experience in international markets does not guarantee regulatory approval or compliance with regulatory requirements in international markets. If we fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in international markets are delayed, our target market will be reduced and our ability to realize the full market potential of our products will be harmed.

 

Zalviso and our other product candidates will require Risk Evaluation and Mitigation Strategies.

 

The FDA Amendments Act of 2007 implemented safety-related changes to product labeling and requires the adoption of REMS. Our product candidates, if approved, will require REMS. The REMS may include requirements for special labeling or medication guides for patients, special communication plans to health care professionals and restrictions on distribution and use. While we have received pre-clearance from the FDA regarding certain aspects of the proposed required REMS for Zalviso, we cannot predict the final REMS to be required as part of any FDA approval of Zalviso. Depending on the extent of the REMS requirements, the launch may be delayed, the costs to commercialize Zalviso may increase substantially and the potential commercial market could be restricted. ARX-02, ARX-03 and ARX-04, if approved, will also require REMS programs that may significantly increase our costs to commercialize these product candidates. Furthermore, risks of sufentanil that are not adequately addressed through proposed REMS for our future product candidates, if approved, may also prevent or delay their approval for commercialization.  

  

 
38

 

 

Recently enacted and future legislation may increase the difficulty and cost for us to commercialize Zalviso and any of our product candidates that may obtain commercial approval in the future, and affect the prices we may obtain.

 

In the United States and some foreign jurisdictions, the legislative landscape continues to evolve. There have been a number of legislative and regulatory changes and proposed changes regarding healthcare systems that could prevent or delay marketing approval of our product candidates, including Zalviso, restrict or regulate post-approval activities and affect our ability to profitably sell any products for which we obtain marketing approval.

 

In the United States, the Health Care Reform Law (as defined below) was enacted in an effort to, among other things, broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, impose new taxes and fees on the health industry and impose additional health policy reforms. Aspects of the Health Care Reform Law that may impact our business include:

 

 

extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

 

 

a deductible 2.3% excise tax, with limited exceptions, on the sale of certain medical devices by the manufacturer of the device;

 

 

new methodologies by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, and for drugs that are
line extensions;

 

 

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;

 

 

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for certain individuals with income at or below 133.0% of the Federal Poverty Level beginning in 2014, thereby potentially increasing manufacturers’ Medicaid rebate liability;

 

 

expansion of healthcare fraud and abuse laws, including the federal False Claims Act and the federal Anti-Kickback Statute, new government investigative powers and enhanced penalties for non-compliance;

 

 

a new requirement to annually report drug samples that manufacturers and distributors provide to physicians;

 

 

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and

 

 

creation of the Independent Payment Advisory Board which has authority to recommend certain changes to the Medicare program that could result in reduced payments for prescription drugs.

 

The Health Care Reform Law has the potential to substantially change health care financing and delivery by both governmental and private insurers, and may also increase our regulatory burdens and operating costs.

 

In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. On August 2, 2011, the Budget Control Act of 2011 created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This included aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and will stay in effect through 2024 unless additional Congressional action is taken. On January 2, 2013, the American Tax Payer Relief Act was signed into law, which, among other things, further reduced Medicare payments to several providers, including hospitals.

 

Moreover, the recently enacted Drug Supply Chain Security Act of 2013, imposes new obligations on manufacturers of pharmaceutical products, among others, related to product tracking and tracing. Among the requirements of this new legislation, manufacturers will be required to provide certain information regarding the drug product to individuals and entities to which product ownership is transferred, label drug product with a product identifier, and keep certain records regarding the drug product.

 

Legislative and regulatory proposals have been made to expand post-approval requirements and further restrict sales and promotional activities for pharmaceutical products. We are not sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be.

 

We expect that additional healthcare reform measures will be adopted within and outside the United States in the future, any of which could negatively impact our business. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare may adversely affect the demand for any drug products for which we may obtain regulatory approval, our ability to set a price that we believe is fair for our products, our ability to obtain coverage and reimbursement approval for a product, our ability to generate revenues and achieve or maintain profitability, and the level of taxes that we are required to pay.

Risks Related to Our Financial Condition and Need for Additional Capital 

 

We have incurred significant losses since our inception, anticipate that we will continue to incur significant losses in 2015 and may continue to incur losses for the foreseeable future.

 

Since our inception in 2005, we have focused primarily on development of our lead product candidate, Zalviso. We have three additional product candidates in development, the Sufentanil Sublingual Tablet BTP Management System, or ARX-02, the Sufentanil/Triazolam Sublingual Tablet, or ARX-03, and Sufentanil Sublingual Single-Dose Acute Pain Tablet, or ARX-04. We have incurred significant net losses in each year since our inception in July 2005, and as of December 31, 2014, we had an accumulated deficit of $178.8 million.

 

We have devoted most of our financial resources to research and development, including our non-clinical development activities and clinical trials. To date, we have financed our operations primarily through the sale of equity securities, debt, government grant funding and proceeds from our collaboration with Grünenthal. The size of our future net losses will depend, in part, on the rate of future expenditures and our ability to generate revenues. We expect to continue to incur substantial expenses as we continue our research and development activities for our product candidates, including addressing issues raised by the FDA related to regulatory review of Zalviso, as well as to support manufacturing and supply for potential approval of Zalviso in Europe, in connection with our collaboration with Grünenthal. To date, none of our product candidates have been commercialized, and if Zalviso or our other product candidates are not successfully developed or commercialized, or if revenues are insufficient following marketing approval, we will not achieve profitability and our business may fail. Our success is also dependent on obtaining regulatory approval to market our product candidates outside of the United States through current and future collaborations which may not materialize or prove to be successful.

 

We have never generated product revenue and may never be profitable.

 

Our ability to generate revenue from commercial sales and achieve profitability depends on our ability, alone or with collaborators, to successfully complete the development of, obtain the necessary regulatory approvals for, and commercialize our product candidates. We may never generate revenues from sales of Zalviso or our other product candidates in the United States. While we have a collaboration with Grünenthal for potential commercialization of Zalviso in Europe and Australia, we may never achieve the development milestones associated with the collaboration, and Grünenthal may never achieve regulatory approval or recognize commercial sales of Zalviso, for which we would receive sales milestone payments and product royalties. In addition, we do not anticipate generating revenues from our other product candidates for the foreseeable future, if ever. Our ability to generate future revenues from product sales depends heavily on our success in:

 

 

obtaining and maintaining regulatory approval for Zalviso;

 

 

launching and commercializing Zalviso, including building or contracting out, a hospital-directed sales force in the United States and collaborating with third parties internationally, including Grünenthal, which may require additional funding; and

 

 

completing the clinical development of, obtaining regulatory approval for, and launching and commercializing ARX-04, ARX-02 and ARX-03, which may require additional funding or corporate partnership resources.

 

 

Because of the numerous risks and uncertainties associated with pharmaceutical product development and the regulatory environment, we are unable to predict the timing or amount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. Our expenses could increase beyond expectations if we are delayed in receiving regulatory approval, or in launching Zalviso, or if we are required by the FDA to complete activities in addition to those we currently anticipate or have already completed.

 

Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. Even if we are able to generate revenues from the sale of any future approved products, we may not become profitable and may need to obtain additional funding to continue operations.

 

We have a limited operating history that may make it difficult to predict our future performance or evaluate our business and prospects.  

 

We were incorporated in 2005. Since inception, our operations have been primarily limited to organizing and staffing our company, developing our technology and undertaking pharmaceutical development and clinical trials for our product candidates, and more recently, preparing for the commercialization of Zalviso. We have not yet obtained regulatory approval of any of our product candidates, including Zalviso. Consequently, any predictions that are made about our future success, or viability, or evaluation of our business and prospects, may not be accurate.

  

 
40

 

 

We will require additional capital and may be unable to raise capital, which would force us to delay, reduce or eliminate our product development programs and could cause us to cease operations.

 

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We expect to incur significant expenditures in connection with our ongoing activities, including conductingARX-04 Phase 3 clinical trials, development activities associated with Zalviso to respond to issues raised by the FDA and other research and development activities to advance our product candidates. While we believe we have sufficient capital resources to continue planned operations through at least the first quarter of 2016, we may need additional capital to continue development of Zalviso, ARX-04 and our other product candidates and will need additional capital to potentially pursue commercialization of any of our product candidates.

 

Future events and circumstances, including those beyond our control, may cause us to consume capital more rapidly than we currently anticipate. For example, in March 2015, we received correspondence from the FDA stating that we needed to complete an additional clinical study. Such development activities can be time consuming and costly. Even if we have sufficient resources to complete an additional clinical study for Zalviso, and we may not depending on the size, scope and potential outcome of the trial, regulatory review for Zalviso, and a potential launch of a commercial product is expensive. In addition, commercialization costs for Zalviso in the United States may be significantly higher than estimated. We may experience technical difficulties in our commercialization efforts or otherwise, which could substantially increase the costs of commercialization. Revenues may be lower than expected and accordingly costs to produce such revenues may exceed those revenues. We will need to seek additional capital to continue operations. Such capital demands could be substantial. To raise capital, we may seek to sell additional equity or debt securities, monetize certain assets including future royalty streams and milestones, obtain a credit facility, or enter into product development, license or distribution agreements with third parties, or divest one or more of our product candidates. Such arrangements may not be available on favorable terms, if at all. Furthermore, any product development, licensing, distribution or sale agreements that we enter into may require us to relinquish valuable rights. We may not be able to obtain sufficient additional funding or enter into a strategic transaction in a timely manner. If adequate funds are not available, we would be required to reduce our workforce, delay, reduce the scope of, or eliminate, one or more of our research and development programs in advance of the date on which we exhaust our cash resources to ensure that we have sufficient capital to meet our obligations and continue on a path designed to preserve stockholder value.

 

Securing additional financing may divert our management from our day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. If we are unable to raise additional capital when required or on acceptable terms, we may be required to:

 

 

significantly delay, scale back or discontinue the development or commercialization of our product candidates;

 

 

seek additional corporate partners for Zalviso on terms that might be less favorable than might otherwise be available; or

 

 

 

relinquish, or license on unfavorable terms, our rights to technologies or product candidates that we otherwise would seek to develop or commercialize ourselves.

 

We may sell additional equity or debt securities to fund our operations, which may result in dilution to our stockholders and impose restrictions on our business.  

 

In order to raise additional funds to support our operations, we may sell additional equity or debt securities which would result in dilution to our stockholders or impose restrictive covenants that may adversely impact our business. The sale of additional equity or convertible debt securities would result in the issuance of additional shares of our capital stock and dilution to all of our stockholders. The incurrence of indebtedness would result in increased fixed payment obligations and could also result in certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected and we may not be able to meet our debt service obligations.

 

We might be unable to service our existing debt due to a lack of cash flow and might be subject to default.  

 

In December 2013, we entered into an amended loan and security agreement, or the Amended Loan Agreement, with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., collectively referred to as Hercules, under which we may borrow up to $40.0 million in three tranches, represented by secured convertible promissory notes. We drew the first tranche of $15.0 million at the closing of the new credit facility and the second tranche of $10 million on June 16, 2014. We will not have access to the third tranche of up to $15.0 million under the current agreement, as it is conditioned upon FDA approval to market Zalviso in the United States by August 1, 2015. We begin making principal payments in April 2015. The scheduled maturity date is October 1, 2017.

 

 
41

 

 

We granted Hercules a first priority security interest in substantially all of our assets, with the exception of our intellectual property, where the security interest is limited to proceeds of intellectual property if it is licensed or sold.

 

If we do not make the required payments when due, either at maturity, or at applicable installment payment dates, or if we breach the agreement or become insolvent, Hercules could elect to declare all amounts outstanding, together with accrued and unpaid interest and penalty, to be immediately due and payable. Additional capital may not be available on terms acceptable to us, or at all. Even if we were able to repay the full amount in cash, any such repayment could leave us with little or no working capital for our business. If we are unable to repay those amounts, Hercules will have a first claim on our assets pledged under the Amended Loan Agreement. If Hercules should attempt to foreclose on the collateral, it is unlikely that there would be any assets remaining after repayment in full of such secured indebtedness. Any default under the Amended Loan Agreement and resulting foreclosure would have a material adverse effect on our financial condition and our ability to continue our operations.

 

We may not secure additional funding from the Department of Defense for advancement ARX-04.

 

In the latter half of 2014, we were notified by the DoD that we had been offered a contract to provide partial funding to support further development of ARX-04. We intend to initiate our first planned Phase 3 trial for ARX-04 by the end of March 2015, but we have postponed other development activities for ARX-04 until we can finalize contract negotiations with the DoD. While we still anticipate receiving some funding to support ARX-04 from the DoD, we may not receive funding in a timely manner, we may receive funding at a level significantly less than our proposal, or we may not receive funding at all. In addition, even if we receive funding, such funding will be subject to audit by the DoD to ensure adherence to specific guidance, policies and procedures. We currently do not have all such required policies and procedures in place as we have never received a government contract before. Even if we are able to implement all required procedures, the DoD may find deficiencies during the course of an audit which could jeopardize, or even eliminate, continued funding from the DoD, as well as require repayment of any funds they had provided us since inception of the contract. Continued delay from the DoD or lack of ARX-04 supportive funding, may adversely affect our ability to continue to advance the development of ARX-04. For example, the initiation of the second planned Phase 3 trial for ARX-04 is contingent on DoD funding.

 

Risks Related to Our Reliance on Third Parties

 

We rely on third party manufacturers to produce our preclinical and clinical drug supplies and intend to rely on third parties to produce commercial supplies of any approved product candidates.

 

Reliance on third party manufacturers entails many risks including:

 

 

the inability to meet our product specifications and quality requirements consistently;

 

 

a delay or inability to procure or expand sufficient manufacturing capacity;

 

 

manufacturing and product quality issues related to scale-up of manufacturing;

 

 

costs and validation of new equipment and facilities required for scale-up;

 

 

a failure to comply with cGMP and similar foreign standards;

 

 

the inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

 

 

termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that is costly or damaging to us;

 

 

the reliance on a limited number of sources, and in some cases, single sources for product components, such that if we are unable to secure a sufficient supply of these product components, we will be unable to manufacture and sell our product candidates in a timely fashion, in sufficient quantities or under acceptable terms;

 

 

the lack of qualified backup suppliers for those components that are currently purchased from a sole or single source supplier;

 

 

operations of our third party manufacturers or suppliers could be disrupted by conditions unrelated to our business or operations, including the bankruptcy of the manufacturer or supplier;

 

 

carrier disruptions or increased costs that are beyond our control; and

 

 

the failure to deliver our products under specified storage conditions and in a timely manner.

 

Any of these events could lead to stock outs, inability to successfully commercialize our products, clinical trial delays, or failure to obtain regulatory approval. Some of these events could be the basis for FDA action, including injunction, recall, seizure, or total or partial suspension of production.

 

We rely on limited sources of supply for the drug component of our product candidates and any disruption in the chain of supply may cause delay in developing and commercializing our product candidates.

 

Currently, we use two established suppliers of sufentanil citrate for our tablets. We only have one supplier qualified for our manufacture of Zalviso. For each product candidate, only one of the two suppliers will be qualified as a vendor with the FDA. If supply from the approved vendor is interrupted, there could be a significant disruption in commercial supply. The alternative vendor would need to be qualified through an NDA supplement which could result in further delay. The FDA or other regulatory agencies outside of the United States may also require additional trials if a new sufentanil supplier is relied upon for commercial production.

  

 
42

 

 

Manufacture of sufentanil sublingual tablets requires specialized equipment and expertise.

 

Ethanol, which is used in the manufacturing process for our sufentanil sublingual tablets, is flammable, and sufentanil is a highly potent, Schedule II compound. These factors necessitate the use of specialized equipment and facilities for manufacture of sufentanil sublingual tablets. There are a limited number of facilities that can accommodate our manufacturing process and we need to use dedicated equipment throughout development and commercial manufacturing to avoid the possibility of cross-contamination. If our equipment breaks down or needs to be repaired or replaced, it may cause significant disruption in clinical or commercial supply, which could result in delay in the process of obtaining approval for or sale of our products. Furthermore, we are using one manufacturer to produce our sufentanil sublingual tablets and have not identified a back-up commercial facility to date. Any problems with our existing facility or equipment, including ongoing expansion, may delay or impair our ability to complete our clinical trials or commercialize our product candidates and increase our cost.

 

Manufacturing issues may arise that could delay or increase costs related to product and regulatory approval,
and commercialization.

 

As we scale up manufacturing of our product candidates and conduct required stability testing, product, packaging, equipment and process-related issues may require refinement or resolution in order to obtain regulatory approval for commercial marketing. In the past we have identified impurities in our product candidates. In the future we may identify significant impurities, which could result in increased scrutiny by the regulatory agencies, delays in clinical program and regulatory approval, increases in our operating expenses, or failure to obtain or maintain approval for our products.

 

Early development and clinical trial manufacturing of Zalviso was conducted at Patheon in Toronto, Canada. Because the DEA requires that sufentanil be manufactured in the United States if our product candidates are marketed in the United States, we transferred our manufacturing capability in the third quarter of 2011 from Patheon in Toronto, Canada to Patheon’s production facility in Cincinnati, Ohio, where we have built out a suite within their existing buildings that will serve as a manufacturing facility for clinical and commercial supplies of sufentanil sublingual tablets. Late stage development and manufacture of registration stability lots, which were utilized in clinical trials, were manufactured at Patheon, Cincinnati. However, we have not yet produced commercial supplies at this facility and we may encounter difficulties in production at the new facility, which may adversely affect our clinical and commercial plans.

 

In January 2013, we entered into a Manufacturing Services Agreement, or the Services Agreement, with Patheon under which Patheon has agreed to manufacture, supply, and provide certain validation and stability services with respect to Zalviso for potential sales in the United States, Canada, Mexico and other countries, subject to agreement by the parties to any additional fees for such other countries. There is no guarantee that Patheon’s services will be satisfactory or that they will continue to meet the strict regulatory guidelines of the FDA or other regulatory agencies. In addition, in January 2013, we entered into an Amended and Restated Capital Expenditure and Equipment Agreement, or the Amended Capital Agreement, with Patheon, relating to the manufacture of sufentanil sublingual tablets. Under the terms of the Amended Capital Agreement, we have made and may make certain future modifications to Patheon’s Cincinnati facility.

 

If Patheon cannot provide us with an adequate supply of sufentanil sublingual tablets, we may be required to pursue alternative sources of manufacturing capacity. Switching or adding commercial manufacturing capability can involve substantial cost and require extensive management time and focus, as well as additional regulatory filings. In addition, there is a natural transition period when a new manufacturing facility commences work. As a result, delays may occur, which can materially impact our ability to meet our desired commercial timelines, thereby increasing our costs and reducing our ability to generate revenue.

 

The facilities of any of our future manufacturers of sufentanil-containing sublingual tablets must be approved by the FDA before commercial distribution from such manufacturers occurs. We do not fully control the manufacturing process of sufentanil sublingual tablets and are completely dependent on these third party manufacturing partners for compliance with the FDA’s requirements for manufacture. In addition, although our third party manufacturers are well established commercial manufacturers, we are dependent on their continued adherence to cGMP manufacturing and acceptable changes to their process. If our manufacturers do not meet the FDA’s strict regulatory requirements, they will not be able to secure FDA approval for their manufacturing facilities. If the FDA does not approve these facilities for the commercial manufacture of sufentanil sublingual tablets, we will need to find alternative suppliers, which would result in significant delays in obtaining FDA approval for Zalviso. These challenges may have a material adverse impact on our business, results of operations, financial condition and prospects.

Related to the Zalviso device, we have conducted multiple Design Validation, Software Verification and Validation, Reprocessing and Human Factors studies, and have manufactured for and completed Phase 3 clinical trials using the intended commercial device. As mentioned above, the CRL from the FDA contains a request for additional information on the Zalviso System to ensure proper use of the device. In March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We have made modifications to the design of the Zalviso device subsequent to the original submission of the Zalviso NDA, which we plan to include as a part of any resubmitted NDA. If we are required to further modify the Zalviso device, we may incur higher costs and experience delays in the approval and ultimate commercialization of Zalviso. Furthermore, if the identified changes to the device are substantial, the FDA may require us to perform further clinical trials or studies in order to approve the device for commercial use.

 

We have manufactured Zalviso devices and supplies on a small scale, including those needed for our Phase 3 clinical trials. We, however, have not yet manufactured Zalviso devices and supplies on a large scale, for commercial purposes. We will not begin commercial scale production of the device until after approval by the FDA. We will continue to rely on contract manufacturers, component fabricators and third party service providers to produce the necessary Zalviso devices for the commercial marketplace. We currently outsource manufacturing and packaging of the controller, dispenser and cartridge components of the Zalviso device to third parties and intend to continue to do so. These purchases and components were made and will continue to be made utilizing short-term purchase agreements and we may not be able to enter into long-term agreements for commercial supply of Zalviso devices with third party manufacturers, or may be unable to do so on acceptable terms. In addition, we may encounter production issues with our current or future contract manufacturers and other third party service providers, including the quality of the components produced, their inability to meet demand or other unanticipated delays including the scale-up and automation process, which would adversely impact our ability to supply our customers with Zalviso, if approved.

 

We may not be able to establish additional sources of supply for device manufacture. Such suppliers are subject to FDA regulations requiring that materials be produced under cGMPs or Quality System Regulations, or QSR, and subject to ongoing inspections by regulatory agencies. Failure by any of our suppliers to comply with applicable regulations may result in delays and interruptions to our product candidate supply while we seek to secure another supplier that meets all regulatory requirements.  

 

Reliance on third party manufacturers entails risks to which we would not be subject if we manufactured the product candidates ourselves, including the possible breach of the manufacturing agreements by the third parties because of factors beyond our control; and the possibility of termination or nonrenewal of the agreements by the third parties because of our breach of the manufacturing agreement or based on their own business priorities.

 

We rely on third parties to conduct, supervise and monitor our clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business.  

 

We utilized contract research organizations, or CROs, for the conduct of our Phase 3 clinical trials of Zalviso, the Phase 2 clinical trial of ARX-04, and our ongoing Phase 3 clinical program for ARX-04. We rely on CROs, as well as clinical trial sites, to ensure the proper and timely conduct of our clinical trials and document preparation. While we have agreements governing their activities, we have limited influence over their actual performance. We have relied and plan to continue to rely upon CROs to monitor and manage data for our clinical programs for Zalviso and our other product candidates, as well as the execution of nonclinical and clinical trials. We control only certain aspects of our CROs’ activities. Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve us of our regulatory responsibilities.

 

We, and our CROs, are required to comply with the FDA’s current good clinical practices, or cGCPs, which are regulations and guidelines enforced by the FDA for all of our product candidates in clinical development. The FDA enforces these cGCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA may require us to perform additional clinical trials before approving our marketing applications. Upon inspection, the FDA may determine that our clinical trials do not comply with cGCPs. Accordingly, if our CROs or clinical trial sites fail to comply with these regulations, we may be required to repeat clinical trials, which would delay the regulatory process.

 

Our CROs are not our employees, and we cannot control whether or not they devote sufficient time and resources to our ongoing clinical and nonclinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials, or other drug development activities which could harm our competitive position. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may allow our potential competitors to access our proprietary technology. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements, or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize Zalviso, or our other product candidates. As a result, our financial results and the commercial prospects for Zalviso and any future product candidates for which we may obtain approval would be harmed, our costs could increase, and our ability to generate revenues could be delayed.

Risks Related to Commercialization of Our Product Candidates

 

The commercial success of Zalviso and our other product candidates, if approved, will depend upon the acceptance of these products by the medical community, including physicians, nurses, patients, and pharmacy and therapeutics committees.

 

The degree of market acceptance of Zalviso and our other product candidates, if approved, will depend on a number of factors, including:

 

 

demonstration of clinical safety and efficacy compared to other products;

 

 

the relative convenience, ease of administration and acceptance by physicians, patients and health care payors;

 

 

the use of Zalviso for the management of moderate-to-severe acute pain in the hospital setting for patient types that were not specifically studied in our Phase 3 trials;

 

 

the prevalence and severity of any AEs or SAEs;

 

 

 

overcoming the perception of sufentanil as a potentially unsafe drug due to its high potency;

 

 

limitations or warnings contained in the FDA-approved label for Zalviso;

 

 

restrictions or limitations placed on Zalviso due to the REMS;

 

 

availability of alternative treatments;

 

 

existing capital investment by hospitals in IV PCA technology;

 

 

pricing and cost-effectiveness;

 

 

the effectiveness of our or any future collaborators’ sales and marketing strategies;

 

 

our ability to obtain hospital formulary approval;

 

 

our ability to obtain and maintain sufficient third party coverage or reimbursement.

 

If Zalviso is approved, but does not achieve an adequate level of acceptance by physicians, nurses, patients and pharmacy and therapeutics committees, or P&T Committees, we may not generate sufficient revenue from Zalviso and we may not become or remain profitable.

 

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we may be unable to generate any revenue.  

 

In order to commercialize any products that may be approved, including Zalviso, we must build our internal sales, marketing, distribution, managerial and other capabilities or make arrangements with third parties to perform these services. We are currently building out our commercial capabilities, including internal sales, marketing, supply chain and medical affairs departments and are active in the recruitment process; however, if delays in, or the inability to, recruit and hire the appropriate individuals occurs, the potential success of approved product candidates, including Zalviso, could be adversely affected. In addition, we plan to enter into agreements with third parties for the distribution of approved product candidates, including Zalviso; however, if there are delays in establishing such relationships or those third parties do not perform as expected, our ability to effectively distribute products would suffer.

 

We have entered into a collaboration with Grünenthal for the commercialization of Zalviso in Europe and Australia and intend to enter into additional strategic partnerships with third parties to commercialize our product candidates outside of the United States. We may also consider the option to enter into strategic partnerships for our product candidates in the United States. We face significant competition in seeking appropriate strategic partners, and these strategic partnerships can be intricate and time consuming to negotiate and document.

 

We may not be able to negotiate future strategic partnerships on acceptable terms, or at all. We are unable to predict when, if ever, we will enter into any strategic partnerships because of the numerous risks and uncertainties associated with establishing strategic partnerships. Our strategy for Zalviso is to develop a hospital-directed sales force to promote the product to healthcare professionals in the United States. Our current or future collaboration partners, if any, may not dedicate sufficient resources to the commercialization of Zalviso or our other product candidates, if approved, or may otherwise fail in their commercialization due to factors beyond our control. If we are unable to establish effective collaborations to enable the sale of Zalviso or our product candidates, if approved, to healthcare professionals and in geographical regions, including the United States, that will not be covered by our own marketing and sales force, or if our potential future collaboration partners do not successfully commercialize our product candidates, if approved, our ability to generate revenues from product sales will be adversely affected.

  

 
45

 

 

If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate sufficient product revenue and may not become profitable. We will be competing with many companies that currently have extensive and well-funded marketing and sales operations. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

 

 

A key part of our business strategy is to establish collaborative relationships to commercialize and fund development and approval of our product candidates, particularly outside of the United States. We may not succeed in establishing and maintaining collaborative relationships, which may significantly limit our ability to develop and commercialize our products successfully, if at all.

 

We will need to establish and maintain successful collaborative relationships to obtain international sales, marketing and distribution capabilities for our product candidates. The process of establishing and maintaining collaborative relationships is difficult, time-consuming and involves significant uncertainty, including:

 

 

our partners may seek to renegotiate or terminate their relationships with us due to unsatisfactory clinical or regulatory results, manufacturing issues, a change in business strategy, a change of control or other reasons;

 

 

our contracts for collaborative arrangements are terminable at will on written notice and may otherwise expire or terminate and we may not have alternatives available to achieve the potential for our products in those territories or markets;

 

 

our partners may choose to pursue alternative technologies, including those of our competitors;

 

 

we may have disputes with a partner that could lead to litigation or arbitration;

 

 

we have limited control over the decisions of our partners and they may change the priority of our programs in a manner that would result in termination of the agreement or add significant delays to the partnered program;

 

 

our ability to generate future payments and royalties from our partners depends upon the abilities of our partners to establish the safety and efficacy of our drug candidates, obtain regulatory approvals and our ability to successfully manufacture and achieve market acceptance of products developed from our product candidates;

 

 

we or our partners may fail to properly initiate, maintain or defend our intellectual property rights, where applicable, or a party may use our proprietary information in such a way as to invite litigation that could jeopardize or potentially invalidate our proprietary information or expose us to potential liability;

 

 

our partners may not devote sufficient capital or resources towards our product candidates; and

 

 

our partners may not comply with applicable government regulatory requirements necessary to successfully market and sell our products.

 

If any collaborator fails to fulfill its responsibilities in a timely manner, or at all, any research, clinical development, manufacturing or commercialization efforts pursuant to that collaboration could be delayed or terminated, or it may be necessary for us to assume responsibility for expenses or activities that would otherwise have been the responsibility of our collaborator. If we are unable to establish and maintain collaborative relationships on acceptable terms or to successfully and timely transition terminated collaborative agreements, we may have to delay or discontinue further development of one or more of our product candidates, undertake development and commercialization activities at our own expense or find alternative sources of capital.

 

If we obtain approval to commercialize our products outside of the United States, a variety of risks associated with international operations could materially adversely affect our business.

 

If any of our product candidates, including Zalviso, are approved for commercialization, we intend to enter into agreements with third parties to market our product candidates outside the United States, which may require us to supply products to the third party such as our existing collaboration with Grünenthal for marketing Zalviso in European countries and Australia. We may be subject to additional risks related to entering into international business relationships, including:

 

 

different regulatory requirements for drug approvals in foreign countries;

 

 

reduced protection for intellectual property rights;

 

 

 

unexpected changes in tariffs, trade barriers and regulatory requirements;

  

 
46

 

 

 

economic weakness, including inflation, or political instability in particular foreign economies and markets;

 

 

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

 

 

foreign taxes, including withholding of payroll taxes;

 

 

foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing business in another country;

 

 

workforce uncertainty in countries where labor unrest is more common than in the United States;

 

 

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

 

 

business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

 

If we, or current and potential partners, are unable to compete effectively, our product candidates may not reach their commercial potential.  

 

The market for Zalviso and our other product candidates is characterized by intense competition and cost pressure. If our product candidates obtain FDA approval, they will compete with a number of existing and future pharmaceuticals and drug delivery devices developed, manufactured and marketed by others. We or our current and potential partners will compete against fully integrated pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies.

 

We believe that Zalviso would compete with a number of opioid-based and non-opioid based treatment options that are currently available, as well as some products that are in development. The hospital market for opioids for moderate-to-severe acute pain is large and competitive. The primary competition for Zalviso is the IV PCA pump, which is widely used in the moderate-to-severe acute pain in the hospital setting. Leading manufacturers of IV PCA pumps include Hospira Inc. (recently acquired by Pfizer), CareFusion Corporation (recently purchased by Becton Dickinson & Co.), Baxter International Inc., Curlin Medical, Inc. and Smiths Medical. The most common opioids used to treat moderate-to-severe acute pain are morphine, hydromorphone and fentanyl, all of which are available as generics both from generic product manufacturers as well as from compounding pharmacies. In addition, branded manufacturers (e.g., Hospira, Inc.) sell pre-filled glass syringes of morphine to fit their IV PCA pump systems.

 

Also available on the market is the Avancen Medication on Demand, or MOD, Oral PCA Device developed by Avancen MOD Corporation. Oral opioids and other agents can be used in this system. In addition, oral and parenteral opioids administered by the nurse are used to manage moderate-to-severe acute pain in the hospital, available both as branded and generic products. These oral opioids, as well as IV PCA opioids, are often used as part of a multi-modal analgesia approach, which might include, in addition to the opioid, NSAIDs, acetaminophen, gabapentanoids and other pain management modalities, as well as local anesthetic blocks to provide temporary blockage of the pain signal, either as a wound infiltration agent or as a nerve block. These local anesthetic agents such as bupivacaine can also utilize controlled-release formulations such as Pacira’s EXPAREL. In addition, Halyard Health, Inc. has developed a medical device, the ON-Q* Pain Relief System, which is a non-narcotic elastomeric pump that automatically and continuously delivers a regulated flow of local anesthetic to a patient’s surgical site or in close proximity to nerves, providing targeted pain relief for up to five days. Additional potential competitors for Zalviso include products in development, including the fentanyl iontophoretic transdermal system, IONSYS, originally developed by ALZA Corporation and Ortho-McNeil Pharmaceutical, Inc., both Johnson & Johnson subsidiaries, and currently under development by The Medicines Company. The Medicines Company has reported that IONSYS has a PDUFA date of April 30, 2015. If approved on this date, IONSYS may be marketed prior to the potential approval of Zalviso which may provide a first-to-market advantage for IONSYS. Cara Therapeutics is developing a kappa opioid agonist, CR845, as an IV agent for the management of post-operative moderate-to-severe pain. Trevena is developing TRV130, an intravenous G protein biased ligand that targets the mu opioid receptor for the treatment of moderate-to-severe acute pain where intravenous therapy is preferred, with a clinical development focus in acute postoperative pain. In January 2015, Trevena initiated a Phase 2b clinical study of TRV130. Recro Pharma is developing an intranasal form of dexmedetomidine as a potential agent for the management of post-operative pain. Finally, Innocoll is developing XARACOLL a controlled-release resorbable implant containing bupivacaine, and Durect has been developing POSIDUR, a controlled-release bupivacaine product candidate utilizing Durect’s SABER technology.

 

Our potential competitors for ARX-02 include products approved in the United States for cancer breakthrough pain, including: ACTIQ and FENTORA, currently manufactured by Teva Pharmaceuticals; Onsolis, currently manufactured by BioDelivery Sciences International, Inc.; Abstral, currently manufactured by ProStrakan Group plc; Lazanda, currently manufactured by Depomed, Inc.; Subsys, currently manufactured by Insys Therapeutics, Inc., as well as products approved in Europe, including Instanyl, currently manufactured by Takeda Pharmaceuticals International GmbH. The active ingredient in all approved products for cancer breakthrough pain is fentanyl. Additional potential competitors for ARX-02 include products in late stage development for cancer breakthrough pain, such as: Fentanyl TAIFUN, currently manufactured by Akela Pharma, Inc.

  

 
47

 

 

We are not aware of any approved or development stage non-IV sedative/analgesic products that would present competition to ARX-03. In the future, there may be products developed or approved for this market which could directly compete
with ARX-03.

 

There are a wide variety of approved injectable and oral opioid products to treat moderate-to-severe acute pain, including IV opioids such as morphine, fentanyl, hydromorphone and meperidine or oral opioids such as oxycodone and hydrocodone. More specifically, competitors for ARX-04 in the emergency department are likely to include generic injectable intravenous opioids such as morphine, hydromorphone and fentanyl. In this environment, ARX-04 may also compete with other branded non-invasive products such as Eagalet’s SPRIX, Hospira’s DYLOJECT, Pfizers OXECTA, Depomed’s NUCYNTA, BMS’s COMBUNOX, Purdue’s OXYFAST, Endo’s OPANA, or generic oral opioids which have moderate to severe acute pain labeling. In the short-stay or ambulatory surgery segment, ARX-04 will likely compete with these products in addition to generic injectable local anesthetics such as bupivacaine, or branded formulations thereof, including Pacira’s EXPAREL. Within the military environment, and in certain civilian settings, ARX-04 competitors may also include intramuscular morphine injections which are marketed by a variety of generic manufacturers.

 

It is possible that any of these competitors could develop or improve technologies or products that would render our product candidates obsolete or non-competitive, which could adversely affect our revenue potential. Key competitive factors affecting the commercial success of our product candidates are likely to be efficacy, safety profile, reliability, convenience of dosing, price and reimbursement.

 

Many of our potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of drug candidates, obtaining FDA and other regulatory approval of products and the commercialization of those products. Accordingly, our competitors may be more successful than we are in obtaining FDA approval for drugs and achieving widespread market acceptance. Our competitors’ drugs or drug delivery systems may be more effective, have fewer adverse effects, be less expensive to develop and manufacture, or be more effectively marketed and sold than any product candidate we may commercialize. This may render our product candidates obsolete or non-competitive before we can recover our losses. We anticipate that we will face intense and increasing competition as new drugs enter the market and additional technologies become available. These entities may also establish collaborative or licensing relationships with our competitors, which may adversely affect our competitive position. Finally, the development of different methods for the treatment of moderate-to-severe acute pain or breakthrough pain could render Zalviso and ARX-02, respectively, non-competitive or obsolete. These and other risks may materially adversely affect our ability to attain or sustain profitable operations.

 

Hospital formulary approval may not be available, or could be subject to certain restrictions for Zalviso and our other product candidates, which could make it difficult for us to sell our products profitably.

 

Obtaining formulary approval can be an expensive and time-consuming process. We cannot be certain if and when we will obtain formulary approval to allow us to sell our products into our target markets. Failure to obtain timely formulary approval will limit our commercial success. If we are successful in obtaining formulary approval, we may need to complete evaluation programs whereby Zalviso is used on a limited basis for certain patient types. Hospitals may seek to obtain Zalviso devices at little or no cost during this evaluation period. Revenue generated from these hospitals during the evaluation period would be minimal. The evaluation period may last several months and there can be no assurance that use during the evaluation period will lead to formulary approval of Zalviso. Further, even successful formulary approval may be subject to certain restrictions based on patient type or hospital protocol. Failure to obtain timely formulary approval for Zalviso would materially adversely affect our ability to attain or sustain profitable operations.

 

Coverage and adequate reimbursement may not be available for Zalviso and our other product candidates, if approved, which could make it difficult for us, or our partners, to sell our products profitably. 

 

Our ability to commercialize Zalviso or any of our other drug candidates, if approved, successfully will depend, in part, on the extent to which coverage and adequate reimbursement will be available from government payor programs at the federal and state levels authorities, including Medicare and Medicaid, private health insurers, managed care plans and other third-party payors.

 

No uniform policy requirement for coverage and reimbursement for drug products exists among third-party payors in the United States. Therefore, coverage and reimbursement can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Our inability to promptly obtain coverage and adequate reimbursement rates from third party payors could significantly harm our operating results, our ability to raise capital needed to commercialize any future approved drugs and our overall financial condition.

  

 
48

 

 

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medical products. There have been a number of legislative and regulatory proposals to change the healthcare system in the United States and in some foreign jurisdictions that could affect our ability to sell our products profitably. These legislative and/or regulatory changes may negatively impact the reimbursement for our products, following approval. The availability of numerous generic pain medications may also substantially reduce the likelihood of reimbursement for Zalviso or any of our other product candidates, if approved. The application of user fees to generic drug products may expedite the approval of additional pain medication generic drugs. We expect to experience pricing pressures in connection with the sale of Zalviso and any of our other product candidates, if approved, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. If we fail to successfully secure and maintain reimbursement coverage for our products or are significantly delayed in doing so, we will have difficulty achieving market acceptance of our products and our business will be harmed.

 

Furthermore, market acceptance and sales of our product candidates, if approved, will depend on reimbursement policies and may be affected by future healthcare reform measures. Government authorities and third party payors, such as private health insurers, hospitals and health maintenance organizations, decide which drugs they will pay for and establish reimbursement levels. We cannot be sure that reimbursement will be available for Zalviso, or any of our other product candidates, if approved. Also, reimbursement amounts may reduce the demand for, or the price of, our products. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize Zalviso, or any of our other product candidates, if approved.

 

Additionally, the regulations that govern marketing approvals, pricing, coverage and reimbursement for new drugs vary widely from country to country. Current and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues able to be generated from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in Zalviso and/or our other drug candidates, even if those drug candidates obtain marketing approval.

 

 The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.

 

If we are found to have improperly promoted off-label uses of our product candidates, including Zalviso, if approved, we may become subject to significant liability. Such enforcement has become more common in the industry. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription drug products. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we receive marketing approval for our product candidates for our proposed indications, physicians may nevertheless use our products for their patients in a manner that is inconsistent with the approved label, if the physicians personally believe in their professional medical judgment it could be used in such manner. However, if the FDA determines that our promotional materials or training constitutes promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an off-label use, which could result in significant civil, criminal and/or administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from government-funded healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, increased losses and diminished profits and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. The FDA or other regulatory authorities could also request that we enter into a consent decree or a corporate integrity agreement, or seek a permanent injunction against us under which specified promotional conduct is monitored, changed or curtailed. If we cannot successfully manage the promotion of our product candidates, including Zalviso, if approved, we could become subject to significant liability, which would materially adversely affect our business and financial condition.

 

Guidelines and recommendations published by government agencies can reduce the use of our product candidates, including Zalviso, if approved.

 

Government agencies promulgate regulations and guidelines applicable to certain drug classes which may include the product candidates that we are developing. Recommendations of government agencies may relate to such matters as usage, dosage, route of administration and use of concomitant therapies. Regulations or guidelines suggesting the reduced use of certain drug classes which may include the product candidates that we are developing or the use of competitive or alternative products as the standard of care to be followed by patients and healthcare providers could result in decreased use of our product candidates, or negatively impact our ability to gain market acceptance and market share.

If we are unable to establish relationships with group purchasing organizations any future revenues or future profitability could be jeopardized.

 

Many end-users of pharmaceutical products have relationships with group purchasing organizations, or GPOs, whereby such GPOs provide such end-users access to a broad range of pharmaceutical products from multiple suppliers at competitive prices and, in certain cases, exercise considerable influence over the drug purchasing decisions of such end-users. Hospitals and other end-users contract with the GPO of their choice for their purchasing needs. We expect to derive revenue from end-user customers that are members of a small number of GPOs, if Zalviso is approved by the FDA. Establishing and maintaining strong relationships with these GPOs will require us to be a reliable supplier, remain price competitive and comply with FDA regulations. The GPOs with whom we have relationships may have relationships with manufacturers that sell competing products, and such GPOs may earn higher margins from these products or combinations of competing products or may prefer products other than ours for other reasons. If we are unable to establish or maintain our GPO relationships, sales of our products and revenue could be negatively impacted.

 

We intend to rely on a limited number of pharmaceutical wholesalers to distribute our product candidates, including Zalviso, if approved.

 

We intend to rely upon pharmaceutical wholesalers in connection with the distribution of our product candidates, including Zalviso, if approved. If we are unable to establish or maintain our business relationships with these pharmaceutical wholesalers on commercially acceptable terms, it could have a material adverse effect on our sales and may prevent us from achieving profitability.

 

Risks Related to Our Business Operations and Industry

 

Failure to comply with the Drug Enforcement Administration regulations, or the cost of compliance with these regulations, may adversely affect our business.

 

Our sufentanil-based products are subject to extensive regulation by the DEA, due to their status as scheduled drugs. Sufentanil is a Schedule II opioid, considered to present the highest risk of abuse. The manufacture, shipment, storage, sale and use of controlled substances are subject to a high degree of regulation, including security, record-keeping and reporting obligations enforced by the DEA and also by comparable state agencies. This high degree of regulation can result in significant costs in order to comply with the required regulations, which may have an adverse effect on the development and commercialization of our product candidates.

 

The DEA limits the availability and production of all Schedule II substances, including sufentanil, through a quota system. The DEA requires substantial evidence and documentation of expected legitimate medical and scientific needs before assigning quotas to manufacturers. Our contract manufacturers have applied annually for a quota on our behalf. We will need significantly greater amounts of sufentanil to implement our commercialization plans for any of our products that may be approved by the FDA in the future, including Zalviso. Any delay or refusal by the DEA in establishing the procurement quota or a reduction in our quota for sufentanil or a failure to increase it over time to meet anticipated increases in demand could delay or stop the clinical development of any of our product candidates or the commercial sale of any approved products. For example, recently, the DEA has denied our Zalviso contract manufacturer the commercial portion of our sufentanil quota. While it is common DEA practice to deny commercial quotas for product candidates not yet approved by the FDA, and we will request commercial quota as we approach FDA approval, there is no guarantee that we will receive such quota in a timely manner or sufficient quantity, which could delay our Zalviso commercial launch. This, in turn, could have a material adverse effect on our business, results of operations, financial condition and prospects.

Our relationships with investigators, health care professionals, consultants, commercial partners, third-party payors, hospitals, and other customers are subject to applicable anti-kickback, fraud and abuse and other healthcare laws, which could expose us to penalties.

 

Healthcare providers, physicians and others play a primary role in the recommendation and prescribing of any products for which we may obtain marketing approval. Our business operations and arrangements with investigators, healthcare professionals, consultants, commercial partners, hospitals, third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws. These laws may constrain the business or financial arrangements and relationships through which we research, market, sell and distribute the products for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws, include, but are not limited to, the following:

 

 

the federal healthcare Anti-Kickback Statute prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, under federal healthcare programs such as Medicare and Medicaid;

 

 

the federal civil and criminal false claims laws and civil monetary penalties, including civil whistleblower or qui tam actions, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false or fraudulent or from knowingly making a false statement to improperly avoid, decrease or conceal an obligation to pay money to the federal government;

 

 

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which, among other things, imposes criminal liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or to obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly or willfully falsifying, concealing, or covering up by any trick or device a material fact or making any materially false statement in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;

 

 

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, impose certain obligations, including mandatory contractual terms, on covered healthcare providers, health plans and clearinghouses, as well as their respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health information, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

 

 

the federal transparency law, enacted as part of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the Health Care Reform Law), and its implementing regulations, requires certain manufacturers of drugs, devices, biologicals and medical supplies to report to the U.S. Department of Health and Human Services information related to payments and other transfers of value provided to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and

 

 

analogous state laws that may apply to our business practices, including but not limited to, state laws that require pharmaceutical companies to implement compliance programs and/or comply with the pharmaceutical industry’s voluntary compliance guidelines; state laws that impose restrictions on pharmaceutical companies’ marketing practices and require manufacturers to track and file reports relating to pricing and marketing information, which requires tracking and reporting gifts, compensation and other remuneration and items of value provided to healthcare professionals and entities.

 

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws. If our operations are found to be in violation of any of these or any other healthcare regulatory laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, increased losses and diminished profits and the curtailment or restructuring of our operations any of which could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses or divert our management’s attention from the operation of our business.

 

Business interruptions could delay us in the process of developing our products and could disrupt our sales.

 

Our headquarters is located in the San Francisco Bay Area, near known earthquake fault zones and is vulnerable to significant damage from earthquakes. We are also vulnerable to other types of natural disasters and other events that could disrupt our operations. We do not carry insurance for earthquakes or other natural disasters and we may not carry sufficient business interruption insurance to compensate us for losses that may occur. Any losses or damages we incur could have a material adverse effect on our business operations.

  

 
51

 

 

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

 

We are highly dependent on principal members of our executive team, the loss of whose services may adversely impact the achievement of our objectives. While we have entered into offer letters with each of our executive officers, any of them could leave our employment at any time, as all of our employees are “at will” employees. Recruiting and retaining other qualified employees for our business, including scientific and technical personnel, will also be critical to our success. There is currently a shortage of skilled executives in our industry, which is likely to continue. As a result, competition for skilled personnel is intense and the turnover rate can be high. We may not be able to attract and retain personnel on acceptable terms given the competition among numerous pharmaceutical companies for individuals with similar skill sets. In addition, failure to succeed in clinical trials, or delays in the regulatory approval process, may make it more challenging to recruit and retain qualified personnel. The inability to recruit or loss of the services of any executive or key employee might impede the progress of our research, development and commercialization objectives. On November 5, 2014, we announced that the Board of Directors has initiated a search to replace Richard King, our President and Chief Executive Officer. On December 15, 2014, we entered into a separation agreement with Mr. King, under the terms of which Mr. King will remain employed with AcelRx in his current position of CEO, until the earliest to occur of the following events: (i) the date that we hire a new Chief Executive Officer; or (ii) the Board requests his resignation; or (iii) March 31, 2015. Mr. King is currently serving as the Chief Commercial Officer as well. While Mr. King has agreed to continue as the President and Chief Executive Officer as per the terms of the separation agreement, and will continue to fill the Chief Commercial Officer role, there can be no assurance that a replacement will be found on a timely basis, or at all. Our inability to find a suitable replacement may have a detrimental impact on the organization and impede the progress of our research, development and commercialization objectives.

 

In the future, we will need to expand our organization, and we may experience difficulties in managing this growth, which could disrupt our operations.

 

As of December 31, 2014, we had 50 full-time employees. As our product candidates mature and approach potential commercialization, we plan to expand our employee base to increase our managerial, sales, marketing, operational, quality, engineering, financial and other resources and to hire more consultants and contractors. Current and future growth impose significant additional responsibilities on our management, including the need to identify, recruit, maintain, motivate and integrate additional employees, consultants and contractors. Also, our management may need to divert a disproportionate amount of its attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our expected growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of additional product candidates. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our ability to generate and/or grow revenues could be reduced, and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize Zalviso and our other product candidates and compete effectively will depend, in part, on our ability to effectively manage any future growth.

 

We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability.

 

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approval exposes us to the risk of product liability claims. Product liability claims might be brought against us by consumers, health care providers, pharmaceutical companies or others selling or otherwise coming into contact with our products. If we cannot successfully defend against product liability claims, we could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product liability claims may result in:

 

 

impairment of our business reputation;

 

 

withdrawal of clinical trial participants;

 

 

costs due to related litigation;

 

 

distraction of management’s attention from our primary business;

 

 

substantial monetary awards to patients or other claimants;

 

 

the inability to commercialize our product candidates; and

 

 

decreased demand for our product candidates, if approved for commercial sale.

 

Our current product liability insurance coverage may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and in the future we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. If and when we obtain marketing approval for our product candidates, we intend to expand our insurance coverage to include the sale of commercial products; however, we may be unable to obtain product liability insurance on commercially reasonable terms or in adequate amounts. On occasion, large judgments have been awarded in class action lawsuits based on drugs that had unanticipated adverse effects. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations
and business.

Our employees, independent contractors, principal investigators, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

 

We are exposed to the risk that our employees, independent contractors, investigators, consultants, commercial partners and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct that violates (1) the laws of the FDA and similar foreign regulatory bodies, including those laws requiring the reporting of true, complete and accurate information to such regulatory bodies; (2) healthcare fraud and abuse laws of the United States and similar foreign fraudulent misconduct laws; and (3) laws requiring the reporting of financial information or data accurately. Specifically, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry are subject to extensive laws designed to prevent misconduct, including fraud, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide range of pricing, discounting, marketing, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials. It is not always possible to identify and deter employee and other third-party misconduct. The precautions we take to detect and prevent inappropriate conduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws. If any such actions are instituted against us, and we are not successful in defending ourselves, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, disgorgement, individual imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

 

Risks Related to Our Intellectual Property

 

If we cannot defend our issued patents from third party claims or if our pending patent applications fail to issue, our business could be adversely affected.

 

To protect our proprietary technology, we rely on patents as well as other intellectual property protections including trade secrets, nondisclosure agreements, and confidentiality provisions. As of December 31, 2014, we are the owner of record of 37 issued patents worldwide. These issued patents cover AcelRx’s sufentanil sublingual tablet, medication delivery devices and platform technology. These issued patents are expected to provide coverage through 2027 – 2030.

 

In addition, we are pursuing a number of U.S. non-provisional patent applications and foreign national applications directed to our product candidates. The patent applications that we have filed and have not yet been granted may fail to result in issued patents in the United States or in foreign countries. Even if the patents do successfully issue, third parties may challenge the patents.

 

Our commercial success will depend in part on successfully defending our current patents against third party challenges and expanding our existing patent portfolio to provide additional layers of patent protection, as well as extending patent protection. There can be no assurance that we will be successful in defending our existing and future patents against third party challenges, or that our pending patent applications will result in additional issued patents.

 

The patent positions of pharmaceutical companies, including us, can be highly uncertain and involve complex and evolving legal and factual questions. No consistent policy regarding the breadth of claims allowed in pharmaceutical patents has emerged to date in the United States. Legal developments may preclude or limit the scope of available patent protection.

 

There is also no assurance that any patents issued to us will not become the subject of adversarial proceedings such as opposition, inter partes review, post-grant review, reissue, re-examination or other post-issuance proceedings, will provide us with competitive advantages, will not be challenged by any third parties, or that the patents of others will not prevent the commercialization of products incorporating our technology. Furthermore, there can be no guarantee that others will not independently develop similar products, duplicate any of our products, or design around our patents.

Litigation involving patents, patent applications and other proprietary rights is expensive and time consuming. If we are involved in such litigation, it could cause delays in bringing our product candidates to market and interfere with our business.

 

Our commercial success depends in part on not infringing patents and proprietary rights of third parties. Although we are not currently aware of litigation or other proceedings or third party claims of intellectual property infringement related to our product candidates, the pharmaceutical industry is characterized by extensive litigation regarding patents and other intellectual property rights.

 

As we enter our target markets, it is possible that competitors or other third parties will claim that our products and/or processes infringe their intellectual property rights. These third parties may have obtained and may in the future obtain patents covering products or processes that are similar to, or may include compositions or methods that encompass our technology, allowing them to claim that the use of our technologies infringes these patents.

 

In a patent infringement claim against us, we may assert, as a defense, that we do not infringe the relevant patent claims, that the patent is invalid or both. The strength of our defenses will depend on the patents asserted, the interpretation of these patents, and our ability to invalidate the asserted patents. However, we could be unsuccessful in advancing non-infringement and/or invalidity arguments in our defense. In the United States, issued patents enjoy a presumption of validity, and the party challenging the validity of a patent claim must present clear and convincing evidence of invalidity, which is a high burden of proof. Conversely, the patent owner need only prove infringement by a preponderance of the evidence, which is a lower burden of proof.

 

If we were found by a court to have infringed a valid patent claim, we could be prevented from using the patented technology or be required to pay the owner of the patent for the right to license the patented technology. If we decide to pursue a license to one or more of these patents, we may not be able to obtain a license on commercially reasonable terms, if at all, or the license we obtain may require us to pay substantial royalties or grant cross licenses to our patent rights. For example, if the relevant patent is owned by a competitor, that competitor may choose not to license patent rights to us. If we decide to develop alternative technology, we may not be able to do so in a timely or cost-effective manner, if at all.

 

In addition, because patent applications can take years to issue and are often afforded confidentiality for some period of time there may currently be pending applications, unknown to us, that later result in issued patents that could cover one or more of our products.

 

It is possible that we may in the future receive, particularly as a public company, communications from competitors and other companies alleging that we may be infringing their patents, trade secrets or other intellectual property rights, offering licenses to such intellectual property or threatening litigation. In addition to patent infringement claims, third parties may assert copyright, trademark or other proprietary rights against us. We may need to expend considerable resources to counter such claims and may not be able to successful in our defense. Our business may suffer if a finding of infringement is established.

 

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.

 

The patent positions of pharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in pharmaceutical patents has emerged to date in the United States. The pharmaceutical patent situation outside the United States is even more uncertain. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. For example, on September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. The United States Patent Office has developed new regulations and procedures to govern the full implementation of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, that became effective March 16, 2013. It is too early to tell what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and
financial condition.

 

Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in the patents that may be issued from the applications we currently or may in the future own or license from third parties. Further, if any patent license we obtain is deemed invalid and/or unenforceable, it could impact our ability to commercialize or partner our technology.

 

Competitors or third parties may infringe our patents. We may be required to file patent infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, or that the third party’s technology does not in fact infringe upon our patents. An adverse determination of any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our related pending patent applications at risk of not issuing. Litigation may fail and, even if successful, may result in substantial costs and be a distraction to our management. We may not be able to prevent misappropriation of our proprietary rights, particularly in countries outside the United States where patent rights may be more difficult to enforce. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential or sensitive information could be compromised by disclosure in the event of litigation. In addition, during the course of litigation there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.  

 

 
54

 

 

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

 

 

we were the first to make the inventions covered by each of our pending patent applications;

 

 

we were the first to file patent applications for these inventions;

 

 

others will not independently develop similar or alternative technologies or duplicate any of our technologies;

 

 

any patents issued to us or our collaborators will provide a basis for commercially viable products, will provide us with any competitive advantages or will not be challenged by third parties; or

 

 

the patents of others will not have an adverse effect on our business.

 

If we do not adequately protect our proprietary rights, competitors may be able to use our technologies and erode or negate any competitive advantage we may have, which could materially harm our business, negatively affect our position in the marketplace, limit our ability to commercialize our product candidates, and delay or render impossible our achievement of profitability.

 

We may be unable to adequately prevent disclosure of trade secrets and other proprietary information.

 

We rely on trade secrets to protect our proprietary know-how and technological advances, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights. Failure to obtain or maintain trade secret protection could enable competitors to use our proprietary information to develop products that compete with our products or cause additional, material adverse effects upon our competitive business position.

 

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications will be due to be paid to the United States Patent and Trademark Office and various foreign governmental patent agencies in several stages over the lifetime of the patents and/or applications.

 

We have systems in place, including use of third party vendors, to manage payment of periodic maintenance fees, renewal fees, annuity fees and various other patent and application fees. The United States Patent and Trademark Office, or the USPTO, and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. There are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If this occurs, our competitors might be able to enter the market, which would have a material adverse effect on our business.

 

We may not be able to enforce our intellectual property rights throughout the world.

 

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to life sciences. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit.

 

Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of intellectual property.

We have not yet registered our trademarks in all of our potential markets, and failure to secure those registrations could adversely affect our business.

 

We have registered our ACELRX mark in the United States, Canada, the European Union and India. We have also registered the mark ACCELERATE. INNOVATE. ALLEVIATE. in the United States. We have additionally applied for registration of our ZALVISO mark in the United States on an intent-to-use basis and that application has been allowed. In early 2014, the FDA accepted the ZALVISO mark as part of the NDA review process. Although we are not currently aware of any oppositions to or cancellations of our registered trademarks or pending applications, it is possible that one or more of the applications could be subject to opposition or cancellation after the marks are registered. The registrations will be subject to use and maintenance requirements. It is also possible that we have not yet registered all of our trademarks in all of our potential markets, and that there are names or symbols other than “ACELRX” that may be protectable marks for which we have not sought registration, and failure to secure those registrations could adversely affect our business. Opposition or cancellation proceedings may be filed against our trademarks and our trademarks may not survive such proceedings.

 

 

Risks Related to Ownership of Our Common Stock

 

The market price of our common stock may be highly volatile.

 

Since our initial public offering, or IPO, in February 2011, the trading price of our common stock has experienced significant volatility and is likely to be volatile in the future. For example, our stock price declined by more than 40% on July 28, 2014, the first trading day following the announcement of the receipt of the CRL from the FDA. In addition, our stock price dropped by 37% on March 9, 2015, the day we announced the correspondence we received from the FDA requesting an additional clinical study for Zalviso. Our stock price could be subject to wide fluctuations in response to a variety of factors, including the following:

 

 

any delay in resubmitting the NDA for Zalviso, submitting an NDA for any of our other product candidates and any adverse development or perceived adverse development with respect to the FDA’s review of any NDA;

 

 

any adverse development or perceived adverse development with respect to the FDA’s regulatory review of Zalviso;

 

 

adverse results or delays in future clinical trials;

 

 

inability to obtain additional funding, including funding necessary for the planned potential commercialization and manufacturing of Zalviso in the United States and advancement of clinical trials for other product candidates;

 

 

failure to successfully develop and commercialize our product candidates;

 

 

changes in laws or regulations applicable to our products;

 

 

inability to obtain adequate product supply for our product candidates, or the inability to do so at acceptable prices;

 

 

adverse regulatory decisions;

 

 

introduction of new products, services or technologies by our competitors;

 

 

failure to meet or exceed financial projections we provide to the public;

 

 

failure to meet or exceed the estimates and projections of the investment community;

 

 

the perception of the pharmaceutical industry by the public, legislatures, regulators and the investment community;

 

 

announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors;

 

 

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies;

 

 

additions or departures of key scientific or management personnel;

 

 

significant lawsuits, including patent or stockholder litigation;

 

 

changes in the market valuations of similar companies;

 

 

sales of our common stock by us or our stockholders in the future; and

 

 

trading volume of our common stock.

 

In addition, the stock market in general, and The NASDAQ Global Market, or NASDAQ, in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance.  

 

 
56

 

 

Historically, our common stock has thinly traded, and in the future may continue to be thinly traded, and our stockholders may be unable to sell at or near asking prices, or at all if they need to sell their shares to raise money or otherwise desire to liquidate such shares.

 

Historically, we have not had a high volume of daily trades in our common stock on NASDAQ. For example, the average daily trading volume in our common stock on NASDAQ during the years ended December 31, 2014 and December 31, 2013, was approximately 700,000 and 540,000 shares per day, respectively. A more active market for our stock has only recently developed and may not be sustained. Our stockholders may be unable to sell their common stock at or near their asking prices, which may result in substantial losses to our investors.

 

The market for our common stock may be characterized by significant price volatility when compared to seasoned issuers, and we expect that our share price will be more volatile than a seasoned issuer for the indefinite future. As noted above, our common stock may be sporadically and/or thinly traded. As a consequence of this lack of liquidity, the trading of relatively small quantities of shares by our stockholders may disproportionately influence the price of those shares in either direction. The price for our shares could, for example, decline significantly in the event that a large number of our common stock are sold on the market without commensurate demand, as compared to a seasoned issuer that could better absorb those sales without adverse impact on its share price.

 

Our principal stockholders and management own a significant percentage of our stock and are able to exert significant control over matters subject to stockholder approval.

 

Our executive officers and directors, together with the stockholders with whom our executive officers and directors are affiliated or associated, beneficially own a significant percentage of our voting stock. Therefore, these stockholders have the ability to influence us through this ownership position. These stockholders are able to determine all matters requiring stockholder approval. For example, these stockholders, acting together, are able to control elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets, or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may believe are in your best interest as one of our stockholders.

 

We incur significant increased costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives.

 

As a public company, we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, as well as the information and reporting requirements of the Exchange Act and other federal securities laws, and rules subsequently implemented by the SEC and NASDAQ, have imposed various requirements on public companies. The costs of compliance with the Sarbanes-Oxley Act and of preparing and filing annual and quarterly reports, proxy statements and other information with the SEC, the Dodd-Frank Act, and regulations promulgated under these statutes, are significant. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly. For example, these rules and regulations make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to incur substantial costs to maintain our current levels of such coverage.

 

As a public company, we are subject to the requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to comply with Section 404 in a timely manner, it may affect the reliability of our internal control over financial reporting. Assessing our staffing and training procedures to improve our internal control over financial reporting is an ongoing process.

 

We have been and will continue to be involved in a substantial effort to implement appropriate processes, document the system of internal control over key processes, assess their design, remediate any deficiencies identified and test their operation. If we fail to comply with the requirements of Section 404, it may affect the reliability of our internal control over financial reporting and negatively impact the quality of disclosure to our stockholders. If we or our independent registered public accounting firm identify and report a material weakness, it could adversely affect our stock price.

 

Sales of a substantial number of shares of our common stock in the public market by our existing stockholders could cause our stock price to fall.

 

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock. All of our shares of common stock outstanding are eligible for sale in the public market, subject in some cases to the volume limitations and manner of sale requirements of Rule 144 under the Securities Act. Sales of stock by our stockholders could have a material adverse effect on the trading price of our common stock.  

 

 
57

 

 

In addition, certain holders of our securities are entitled to certain rights with respect to the registration of their shares of common stock under the Securities Act. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act. We registered for resale 3,070,000 shares of our common stock held by certain selling stockholders on a shelf registration statement that became effective on June 12, 2014. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

 

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

 

We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our
existing stockholders.

 

Pursuant to the 2011 Incentive Plan, our management is authorized to grant stock options and other equity-based awards to our employees, directors and consultants. The number of shares available for future grant under our 2011 Incentive Plan will automatically increase each year by 4% of all shares of our capital stock outstanding as of December 31 of the prior calendar year, subject to the ability of our board of directors to take action to reduce the size of the increase in any given year. Currently, we plan to register the increased number of shares available for issuance under our 2011 Incentive Plan each year. If our board of directors elects to increase the number of shares available for future grant by the maximum amount each year, our stockholders may experience additional dilution, which could cause our stock price to fall.

 

Our involvement in securities-related class action litigation could divert our resources and management's attention and harm our business.

 

The stock markets have from time to time experienced significant price and volume fluctuations that have affected the market prices for the common stock of pharmaceutical companies. These broad market fluctuations may cause the market price of our common stock to decline. In addition, the market price of our common stock may vary significantly based on AcelRx specific events, such as receipt of a CRL, negative clinical results, or other negative feedback from the FDA or other regulatory agencies. In the past, securities-related class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies often experience significant stock price volatility in connection with their investigational drug candidate development programs and the FDA's review of their NDAs.

 

On October 1, 2014, a securities class action complaint was filed in the U.S. District Court for the Northern District of California against us and certain of our current and former officers. The complaint alleges that between December 2, 2013 and September 25, 2014, we and certain of our officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with statements related to our lead drug candidate, Zalviso. The complaint seeks unspecified damages, interest, attorneys’ fees, and other costs. On December 1, 2014, three purported shareholders filed motions to appoint lead plaintiff and to appoint lead counsel. On February 24, 2015, the court issued an order appointing the lead plaintiff and lead counsel in the matter. Lead Plaintiff has until April 10, 2015 to file an amended complaint. The last day for us to respond to the amended complaint is May 26, 2015. This lawsuit and any future related lawsuits are subject to inherent uncertainties, and the actual defense and disposition costs will depend upon many unknown factors. The outcome of such lawsuits is necessarily uncertain. Securities-related class action litigation often is expensive and diverts management's attention and our financial resources, which could adversely affect our business. Further, any negative outcome from such lawsuit could result in payments of monetary damages, or adversely affect our products, and accordingly our business, financial condition, or results of operations could be materially and adversely affected.

 

There can be no assurance that a favorable final outcome will be obtained in this case or any subsequent related case. Defending any lawsuit is costly and can impose a significant burden on management and employees. Any litigation to which we are a party may result in an onerous or unfavorable judgment that may not be reversed upon appeal or in payments of monetary damages not covered by insurance, or we may decide to settle lawsuits on unfavorable terms, which could adversely affect our business, financial conditions, or results of operations.

 

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

 

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be limited. The completion of the July 2013 public equity offering, together with our public equity offering in December 2012, our initial public offering, private placements and other transactions that have occurred, have triggered such an ownership change. In addition, since we will need to raise substantial additional funding to finance our operations, we may undergo further ownership changes in the future. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards to offset United States federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us.

  

 
58

 

 

 

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

 

We have never declared or paid any cash dividends on our capital stock, and we are prohibited from doing so under the terms of our Amended Loan Agreement with Hercules. Regardless of the restrictions in our Amended Loan Agreement with Hercules or the terms of any potential future indebtedness, we anticipate that we will retain all available funds and any future earnings to support our operations and finance the growth and development of our business and, therefore, we do not expect to pay cash dividends in the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may
deem relevant.

 

Provisions in our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders or remove our current management.

 

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our current management. These provisions include:

 

 

authorizing the issuance of “blank check” preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval;

 

 

limiting the removal of directors by the stockholders;

 

 

a staggered board of directors;

 

 

prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders;

 

 

eliminating the ability of stockholders to call a special meeting of stockholders; and

 

 

establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon at stockholder meetings.

 

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by our board of directors. This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by or beneficial to our stockholders. Further, other provisions of Delaware law may also discourage, delay or prevent someone from acquiring us or merging with us.

None.

 

Item 2. Properties

 

We lease approximately 25,893 square feet of office and laboratory space in Redwood City, California under an agreement that expires in January 2018. We believe that our facilities are adequate to meet our current needs.

 

 

Item 3. Legal Proceedings

 

On October 1, 2014, a securities class action complaint was filed in the U.S. District Court for the Northern District of California against AcelRx and certain of our current and former officers. The complaint alleges that between December 2, 2013 and September 25, 2014, AcelRx and certain of our officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with statements related to our lead drug candidate, Zalviso. The complaint seeks unspecified damages, interest, attorneys’ fees, and other costs. On December 1, 2014, three purported shareholders filed motions to appoint lead plaintiff and to appoint lead counsel. On February 24, 2015, the court issued an order appointing the lead plaintiff and lead counsel in the matter. Lead Plaintiff has until April 10, 2015 to file an amended complaint. The last day for the Company to respond to the amended complaint is May 26, 2015. We believe that we have meritorious defenses and intend to defend against this lawsuit vigorously.

 

 
59

 

 

This lawsuit and any future related lawsuits are subject to inherent uncertainties, and the actual defense and disposition costs will depend upon many unknown factors. The outcome of such lawsuits is necessarily uncertain. Securities-related class action litigation often is expensive and diverts management's attention and our financial resources, which could adversely affect our business. Further, any negative outcome from such lawsuit could result in payments of monetary damages, or adversely affect our products, and accordingly our business, financial condition, or results of operations could be materially and adversely affected.

 

There can be no assurance that a favorable final outcome will be obtained in this case or any subsequent related case.  Defending any lawsuit is costly and can impose a significant burden on management and employees. Any litigation to which we are a party may result in an onerous or unfavorable judgment that may not be reversed upon appeal or in payments of monetary damages not covered by insurance, or we may decide to settle lawsuits on unfavorable terms, which could adversely affect our business, financial conditions, or results of operations.

 

From time to time we may be involved in additional legal proceedings arising in the ordinary course of business.

Dividend Policy

 

We have never declared or paid any cash dividends on our capital stock, and we are prohibited from doing so under the terms of our loan and security agreement with Hercules. Regardless of the restrictions in our loan and security agreement with Hercules or the terms of any potential future indebtedness, we anticipate that we will retain all available funds and any future earnings to support our operations and finance the growth and development of our business and, therefore, we do not expect to pay cash dividends in the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may
deem relevant.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

 

The following discussion and analysis should be read in conjunction with our audited financial statements and the related notes that appear elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements involve risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under “Item 1A. Risk Factors” and elsewhere in this Annual Report on Form 10-K. Please refer to the section entitled “Forward-Looking Statements” in this Annual Report on Form 10-K.

 

Overview

 

We are a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain. Our lead product candidate is ZalvisoTM, formerly known as ARX-01. Zalviso is intended for the management of moderate-to-severe acute pain in hospitalized adult patients. Zalviso consists of sufentanil sublingual tablets delivered by the Zalviso System, a needle-free, handheld, patient-administered, pain management system (together, “Zalviso”).

 

On July 25, 2014, the U.S. Food and Drug Administration, or FDA, issued a Complete Response Letter, or CRL, for our New Drug Application, or NDA, for Zalviso. The CRL contains requests for additional information on the Zalviso System to ensure proper use of the device. The requests include submission of data demonstrating a reduction in the incidence of optical system errors, changes to address inadvertent dosing, among other items, and submission of additional data to support the shelf life of the product. In the third quarter of 2014, we held a Type A meeting with the FDA to discuss the Zalviso CRL received in July. During the meeting we discussed the resubmission of the Zalviso NDA and the steps necessary for the resubmission. In advance of resubmitting our Zalviso NDA, we agreed with the FDA to submit protocols for the bench testing and Human Factors, or HF, studies for their review and comment. In addition, the FDA requested in the minutes of the meeting that we provide a risk assessment that analyzes the risks associated with inadvertent dosing and the rationale that bench testing and HF studies are sufficient to address the specific items included in the CRL. We submitted the protocols and this rationale in the fourth quarter of 2014. In January 2015, we received feedback from the FDA on the protocol and the planned analysis of the results of the bench test. No modifications to the conduct of the bench test were necessary; however, in response to the FDA’s request, we refined the planned analysis of the bench test results. In February 2015, we received feedback from the FDA on the HF protocols. In this feedback, the FDA confirmed that the HF studies as proposed were acceptable to evaluate the design changes related to inadvertent dispensing of tablets. In March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. As a result of this most recent FDA communication and the need for clarity with the FDA, the resubmission of the Zalviso NDA is on hold. We will provide an update on the timing of the resubmission of the Zalviso NDA after we obtain more information from the FDA. The FDA has precleared certain aspects of our proposed Risk Evaluation and Mitigation Strategy, or REMS, and indicated that they will continue discussion of our proposed REMS after the Zalviso NDA has been resubmitted.

 

Zalviso

 

Zalviso is an investigational, pre-programmed, non-invasive, system to allow hospital patients with moderate-to-severe acute pain to self-dose with sufentanil sublingual tablets to manage their pain. Zalviso is designed to help address certain problems associated with post-operative intravenous patient-controlled analgesia, by offering:

 

 

A high therapeutic index opioid: Zalviso uses sufentanil, an opioid that has a high therapeutic index. The therapeutic index is the ratio of the effective dose versus the lethal dose. In animal studies, the therapeutic index for sufentanil was approximately 100 times larger than fentanyl and 300 times larger than morphine.

 

 

A non-invasive route of delivery: Zalviso utilizes a sufentanil tablet which allows for a sublingual (under the tongue) route of delivery. Sufentanil is highly lipophilic which provides for rapid absorption in the fatty cells (or mucosal tissue) found under the tongue, and for rapid transit across the blood-brain barrier to reach the mu-opioid receptors in the brain. The sublingual delivery used by Zalviso provides rapid onset of analgesia. The sublingual delivery system also eliminates the risk of IV-related analgesic gaps and IV complications, such as catheter-related infections. In addition, because patients do not require direct connection to an IV PCA infusion pump through IV tubing, Zalviso allows for ease of patient mobility.

 

 

A simple, pre-programmed PCA solution: Zalviso allows patients to self-dose sufentanil sublingual tablets via a pre-programmed, secure system designed to eliminate the risk of programming errors.

  

 
64

 

 

We submitted an NDA for Zalviso in September 2013 and, in December 2013 we announced that the FDA accepted for filing the Zalviso NDA. As mentioned above, the FDA issued a CRL for Zalviso on July 25, 2014. As mentioned above, in March 2015, we received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies we have performed in response to the issues identified in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. We plan to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study.

 

ARX-04

 

We are also developing a Sufentanil Sublingual Single-Dose Tablet, or ARX-04, for the treatment of moderate-to-severe acute pain to be administered by a healthcare professional to a patient in medically supervised settings of acute pain, such as in the emergency room, or for post-operative patients who are transitioning from the operating room to the recovery floor, or who are recovering from either short-stay or ambulatory surgery, and do not require more long-term patient-controlled analgesia, as well as for battlefield casualty treatment, and by paramedics during patient transport. In December 2013, we completed an End-of-Phase 2 Meeting with the FDA to identify a Phase 3 program pathway forward for evaluation of ARX-04. We plan to initiate a pivotal Phase 3 trial for ARX-04 in patients with post-operative pain following abdominal surgery by the end of March 2015. Pending completion of enrollment, we anticipate data from this study in the fourth quarter of 2015.

 

We have also been notified by the Department of Defense, or DoD, that they are preparing a contract to provide partial funding to support further development of ARX-04. We are currently engaged in the contracting process with the DoD to determine the nature, scope, amount and timing of the contract. As noted above, we plan to initiate a Phase 3 trial by the end of March 2015 so as to not sustain additional delays in the development of ARX-04 while we continue contract negotiations with the DoD. We believe the DoD can be supportive of key aspects of the continued development of ARX-04 but we do not currently have a timeline by which we may receive funding.

 

In the first half of 2015, contingent on DoD funding, we plan to initiate our second planned Phase 3 clinical trial, an open-label safety study of patients who present to the emergency room with moderate-to-severe pain due to trauma or injury. We expect top-line data from this trial in the second half of 2015. Approximately 40 patients are planned to be enrolled in this study. Timing of this trial is currently pending finalization of the DoD contract. Should we have delays in such contract negotiations, we may elect to delay this Phase 3 trial beyond the first half of 2015.

 

Financial Overview

 

We have incurred net losses and generated negative cash flows from operations since inception and expect to incur losses in the future as we continue our research and development activities and pre-commercialization activities. As we pursue development of our product candidates, including regulatory review and potential commercial development, subject to FDA approval, of our product candidates, we expect the business aspects of our company to become more complex. In the future, we plan to add personnel and incur additional costs related to the maturation of our business and the potential commercialization of Zalviso, our lead product candidate. In addition, we believe that continued investment in research and development is critical to attaining our strategic objectives. In order to develop our product candidates as commercially viable therapeutics, we expect to expend significant resources for expertise in manufacturing, regulatory affairs, clinical research and other aspects of pharmaceutical development.

 

To date, we have funded our operations primarily through the issuance of equity securities, borrowings, payments from our corporate collaboration and our research grants.

 

Our revenues to date have consisted primarily of revenues from our collaboration with Grünenthal and our research grant with the USAMRMC. We have recognized in full, as revenue, our $5.6 million grant from the USAMRMC as of December 31, 2013.

 

As mentioned above, we have been notified by the DoD that we have been offered a contract to provide partial funding to support further development of ARX-04. We are currently engaged in the contracting process with the DoD to determine the nature, scope, amount and timing of the contract.

 

There can be no assurance that we will produce other collaborative agreement revenues or receive additional funding from USAMRMC or other research-related grant awards in the future. We expect revenues to continue to fluctuate from period-to–period. There can be no assurance that our existing collaboration with Grünenthal will continue beyond the initial term, or that we will be able to meet the milestones specified in this agreement or that we will obtain marketing approval for our product candidates and subsequently generate revenue from those product candidates in excess of our operating expenses.

 

Our net losses were $33.4 million and $23.4 million during the years ended December 31, 2014 and 2013, respectively. As of December 31, 2014, we had an accumulated deficit of $178.8 million. As of December 31, 2014, we had cash, cash equivalents and investments totaling $75.4 million compared to $103.7 million as of December 31, 2013.

 

In December 2013, we entered into an amended loan and security agreement, or the Amended Loan Agreement, with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., collectively referred to as Hercules, under which we may borrow up to $40.0 million in three tranches, represented by secured convertible promissory notes. The Amended Loan Agreement amends and restates the loan and security agreement with Hercules dated as of June 29, 2011, or the Original Loan Agreement. We borrowed the first tranche of $15.0 million upon closing of the transaction on December 16, 2013 and used approximately $8.6 million of the proceeds from the first tranche to repay our obligations under the Original Loan Agreement with Hercules. On June 16, 2014, we borrowed the second tranche of $10.0 million. On September 24, 2014, we entered into an amendment, or the Amendment, to the Amended Loan Agreement with Hercules. The Amendment extends the time period under which we can draw down the third tranche, of up to $15.0 million, from March 15, 2015 to August 1, 2015, subject to our obtaining approval for Zalviso from the FDA. We do not believe we will receive FDA approval of Zalviso by August 1, 2015 and as such, will not have access to the third tranche under the current agreement. The interest rate for each tranche will be calculated at a rate equal to the greater of either (i) 9.10% plus the prime rate as reported from time to time in The Wall Street Journal minus 5.25%, and (ii) 9.10%. Payments under the Amended Loan Agreement are interest only until April 1, 2015 followed by equal monthly payments of principal and interest through the scheduled maturity date on October 1, 2017, or the Loan Maturity Date. In addition, a final payment equal to $1.7 million will be due on the Loan Maturity Date, or such earlier date specified in the Amended Loan Agreement. Our obligations under the Amended Loan Agreement are secured by a security interest in substantially all of our assets, other than our intellectual property.

As of December 31, 2014, the outstanding principal owed to Hercules was $25.0 million.

 

In December 2013, we announced a commercial collaboration with Grünenthal, covering the territory of the European Union, certain other European countries and Australia for Zalviso for use in the management of moderate-to-severe acute pain within a hospital, hospice, nursing home or other medically supervised setting. We retain all rights in remaining countries, including the United States, Asia and Latin America.

 

Under the terms of the agreement with Grünenthal, we received an upfront cash payment of $30.0 million in December 2013, and in the third quarter of 2014, we received a milestone payment of $5.0 million related to the Marketing Authorization Application, or MAA submission to the European Medicines Agency, or EMA. We are eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA. If approved, we are eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts ($28.5 million) and net sales target achievements ($171.5 million). Grünenthal will also make tiered royalty, supply and trademark fee payments in the mid-teens up to the mid-twenties percent range, on net sales of Zalviso in the Grünenthal territory.

 

Grünenthal will be responsible for all commercial activities for Zalviso, including obtaining and maintaining pharmaceutical product regulatory approval in the Grünenthal territory. We will be responsible for obtaining and maintaining device regulatory approval in the Grünenthal territory and manufacturing and supply of Zalviso to Grünenthal for commercial sales.

 

In July 2014, Grünenthal filed an MAA with the EMA under the centralized procedure in the European Union, or EU, for Zalviso for the management of moderate-to-severe acute pain in adult patients in a medically-supervised environment. In the fourth quarter of 2014, Grünenthal received 120-day questions from the EMA per the EMA’s standard regulatory review process. We have been working with Grunenthal towards the submission of the response to the 120-day questions. Grunenthal is currently working to complete the response and submit it to the EMA by the end of March 2015. Assuming the EMA accepts this filing, we anticipate a Committee for Medicinal Products for Human Use, or CHMP, opinion in the summer of 2015 and a final decision by the EMA in the fall of 2015.

 

Critical Accounting Estimates

 

Based on a critical assessment of our accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes that our financial statements are fairly stated in accordance with accounting principles generally accepted in the United States, and meaningfully present our financial condition and results of operations.

 

The accompanying discussion and analysis of our financial condition and results of operations are based upon our financial statements and the related disclosures, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts in our financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. Note 1 of Notes to Financial Statements describes the significant accounting policies used in the preparation of the financial statements. Certain of these significant accounting policies are considered to be critical accounting policies, as defined below.

 

A critical accounting policy is defined as one that is both material to the presentation of our financial statements and requires management to make difficult, subjective or complex judgments that could have a material effect on our financial condition and results of operations. Specifically, critical accounting estimates have the following attributes: (i) we are required to make assumptions about matters that are highly uncertain at the time of the estimate; and (ii) different estimates we could reasonably have used, or changes in the estimate that are reasonably likely to occur, would have a material effect on our financial condition or results of operations.

 

We believe the following policies to be the most critical to an understanding of our financial condition and results of operations because they require us to make estimates, assumptions and judgments about matters that are inherently uncertain. Management has discussed the development, selection and disclosure of the following estimates with the Audit Committee.  

 

 
66

 

 

Revenue Recognition

 

We recognize revenue when all of the following four basic revenue recognition criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured.

 

Revenue generated from collaboration agreements typically includes upfront signing or license fees, cost reimbursements, development and manufacturing services, milestone payments and royalties on future licensee’s product sales.

 

Revenue from non-refundable license, technology access or other payments under license and collaborative agreements where we have a continuing obligation to perform is recognized as revenue over the expected period of the continuing performance obligation. We estimate the performance period at the inception of the arrangement and re-evaluate it each reporting period. This re-evaluation may shorten or lengthen the period over which the remaining revenue is recognized. Changes to these estimates are recorded on a prospective basis.

 

We account for multiple-element arrangements, such as license and commercialization agreements in which a customer may purchase several deliverables, in accordance with ASC Topic 605-25, Revenue Recognition—Multiple-Element Arrangements, or ASC 605-25. We evaluate if the deliverables in the arrangement represent separate units of accounting. In determining the units of accounting, we evaluate certain criteria, including whether the deliverables have value to our customers on a stand-alone basis. Factors considered in this determination include whether the deliverable is proprietary to us, whether the customer can use the license or other deliverables for their intended purpose without the receipt of the remaining elements, whether the value of the deliverable is dependent on the undelivered items, and whether there are other vendors that can provide the undelivered items. Deliverables that meet these criteria are considered a separate unit of accounting. Deliverables that do not meet these criteria are combined and accounted for as a single unit of accounting.

 

For revenue agreements with multiple-element arrangements, such as the collaboration and license agreement with Grünenthal, we allocate revenue to each non-contingent element based on the relative selling price of each element. When applying the relative selling price method, we determine the selling price for each deliverable using vendor-specific objective evidence, or VSOE, of selling price or third-party evidence, or TPE, of selling price. If neither exists we use best estimated selling price, or BESP, for that deliverable. Revenue allocated is then recognized when the four basic revenue recognition criteria, mentioned above, are met for each element.

 

Additionally, we recognize milestone payments, which are subject to substantive contingencies, upon completion of specified milestones, which represents the culmination of an earnings process, according to contract terms. Royalty revenues are generally recognized when earned and collectability of the related royalty payment is reasonably assured.

 

We recognize cost reimbursement revenue under agreements, including our grant agreement with the USAMRMC, as the related research and development costs for services are rendered.

 

Deferred revenue represents the portion of research or license payments received which have not been earned.

 

Research and Development Expenses

 

We expense research and development expenses as incurred. Research and development expenses consist primarily of direct and research-related allocated overhead costs such as facilities costs, salaries and related personnel costs, and material and supply costs. In addition, research and development expenses include costs related to clinical trials to validate our testing processes and procedures and related overhead expenses. Expenses resulting from clinical trials are recorded when incurred based in part on factors such as estimates of work performed, patient enrollment, progress of patient studies and other events. We make good faith estimates that we believe to be accurate, but the actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including our clinical development plan.

 

Share-Based Compensation

 

We measure and recognize compensation expense for all share-based payment awards made to our employees and directors, including employee stock options and employee stock purchases related to the Employee Share Purchase Plan, or ESPP, on estimated fair values. The fair value of equity-based awards is amortized over the vesting period of the award using a straight-line method.  

 

 
67

 

 

To estimate the value of an award, we use the Black-Scholes option pricing model. This model requires inputs such as expected life, expected volatility and risk-free interest rate. These inputs are subjective and generally require significant analysis and judgment to develop. Estimates of expected life are primarily determined using the simplified method in accordance with guidance provided by the Securities and Exchange Commission, or SEC. Volatility is derived from historical volatilities of several public companies within our industry that are deemed to be comparable to our business because we do not have sufficient history on the volatility of our common stock relative to our expected life assumptions. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected life assumption. We review our valuation assumptions quarterly and, as a result, it is likely we will change our valuation assumptions used to value share based awards granted in future periods. Further, we are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. If factors change and different assumptions are employed in determining the fair value of stock based awards, the stock based compensation expense recorded in future periods may differ significantly from what was recorded in the current period.

 

Liabilities Associated with Warrants

 

Warrants to Purchase Common Stock

 

In connection with the private placement equity financing in June 2012, or PIPE, we issued PIPE warrants to purchase up to 2,630,103 shares of common stock. Under the terms of the PIPE warrants, upon certain transactions, including a merger, tender offer, sale of all or substantially all of the assets of AcelRx or if a person or group shall become the owner of 50% of our issued and outstanding common stock, which is outside of our control, each PIPE warrant holder may elect to receive a cash payment in exchange for the warrant, in an amount determined by application of the Black-Scholes option-pricing model. Accordingly, the PIPE warrants are recorded as a liability at fair value at the end of each reporting period, as determined by the Black-Scholes option-pricing model and changes to the fair value are recorded in interest income and other income (expense), net. The inputs for the Black-Scholes option-pricing model include exercise price of the PIPE warrants, market price of the underlying common shares, expected term, volatility based on a group of our peers and the risk-free rate corresponding to the expected term of the PIPE warrants. These inputs are subjective and generally require significant analysis and judgment to develop. Changes to the inputs could significantly impact the estimated fair value of the PIPE warrants, and since issuance of the PIPE warrants through December 31, 2014, changes in our stock price have had a significant impact to the estimated fair value of the PIPE warrants.

 

Warrants to Purchase Convertible Preferred Stock

 

Freestanding warrants to purchase shares of our convertible preferred stock were classified as liabilities on our balance sheets at fair value because the warrants could have conditionally obligated us to redeem the underlying convertible preferred stock. The warrants were subject to remeasurement at each balance sheet date, and any change in fair value was recognized as a component of interest income and other income (expense), net, in the statements of comprehensive loss. We estimated the fair value of these warrants at the respective balance sheet dates using the Black-Scholes option-pricing model. We used assumptions to estimate the fair value of the warrants including the remaining contractual terms of the warrants, risk-free interest rates, expected dividend yields and the fair value and expected volatility of the underlying stock. These assumptions were subjective and the fair value of the warrants to purchase convertible preferred stock could have differed significantly had we used different assumptions.

 

Upon the completion of our IPO in February 2011, all of our warrants to purchase convertible preferred stock had been exercised or converted into warrants to purchase common stock. At that time, the then-current aggregate fair value of these warrants was reclassified from liabilities to additional paid-in capital and we will no longer remeasure the liability associated with these warrants to purchase convertible preferred stock to fair value.

 

Results of Operations

 

Our results of operations have fluctuated from period to period and may continue to fluctuate in the future, based upon the progress of our research and development efforts and variations in the level of expenses related to developmental efforts during any given period. Results of operations for any period may be unrelated to results of operations for any other period. In addition, historical results should not be viewed as indicative of future operating results. We are subject to risks common to companies in our industry and at our stage of development, including risks inherent in our research and development efforts, reliance upon our collaborator, enforcement of our patent and proprietary rights, need for future capital, potential competition and uncertainty of clinical trial results or regulatory approvals or clearances. In order for a product candidate to be commercialized based on our research, we and our collaborators must conduct preclinical tests and clinical trials, demonstrate the efficacy and safety of our product candidates, obtain regulatory approvals or clearances and enter into manufacturing, distribution and marketing arrangements, as well as obtain market acceptance.

Years Ended December 31, 2014, 2013 and 2012

 

Revenue

 

To date, we have not generated any commercial product revenue. We do not expect to receive any commercial sales revenue from any product candidates that we develop until we, or our collaborators, obtain regulatory approval and commercialize
our products.

 

During the year ended December 31, 2014, we recognized $4.6 million in revenue under our collaboration agreement with Grünenthal related to the MAA submission. In addition, we recognized $0.6 million of previously deferred revenue related to research and development services and our obligation to participate in the joint steering committee under the collaboration agreement during the year ended December 31, 2014. During the year ended December 31, 2013, we recognized $27.4 million in revenue attributable to the Grünenthal license.

 

Revenue for the year ended December 31, 2014 was $5.2 million, related to our collaboration agreement with Grünenthal. Revenue for the year ended December 31, 2013 was $29.5 million, $27.4 million of which related to our collaboration with Grünenthal and $2.1 million related to our grant with the USAMRMC. Revenue for the year ended December 31, 2012 was $2.4 million, and was generated from our grant from the USAMRMC.

 

Collaboration agreement

 

In December 2013, we announced a commercial collaboration with Grünenthal, covering the territory of the European Union, certain other European countries and Australia for Zalviso for potential use in pain treatment within or dispensed by a hospital, hospice, nursing home or other medically supervised setting. We retain all rights in remaining countries, including the United States, Asia and Central and South America.

 

Under the terms of the agreement, we received an upfront cash payment of $30.0 million in December 2013, and a milestone payment of $5.0 million related to the MAA submission in the third quarter of 2014. We are eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA. If approved, we are eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts and net sales target achievements. Grünenthal will also make tiered royalty, supply and trademark fee payments in the mid-teens up to the mid-twenties percent range, on net sales of Zalviso in the Grünenthal territory.

 

Grünenthal will be responsible for all commercial activities for Zalviso, including obtaining and maintaining pharmaceutical product regulatory approval in the Grünenthal territory. We will be responsible for obtaining and maintaining device regulatory approval in the Grünenthal territory and manufacturing and supply of Zalviso to Grünenthal for commercial sales. A CE Mark (#611742) for Zalviso was obtained in the fourth quarter 2014 which specifies AcelRx as the device design authority and manufacturer.

 

Research Grant

 

In May 2011, we received a grant award of $5.6 million from the USAMRMC for the development of ARX-04, a sufentanil sublingual tablet for the treatment of moderate-to-severe acute pain. Revenue related to this grant award was recognized as the related research and development expenses were incurred. As of December 31, 2013, we had completed all grant-supported research and development activities and the $5.6 million grant had been recognized in full.

 

Research and Development Expenses

 

Conducting research and development is central to our business model. The majority of our operating expenses to date have been for research and development activities related to Zalviso. Research and development expenses included the following:

 

 

expenses incurred under agreements with contract research organizations and clinical trial sites;

 

 

employee- and consultant-related expenses, which include salaries, benefits and stock-based compensation;

 

 

payments to third party pharmaceutical and engineering development contractors;

 

 

payments to third party manufacturers; and

 

 

depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, and equipment and laboratory and other supply costs.

 

Product candidates in late stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of late stage clinical trials. We will incur substantial future expenditures as we seek to continue development of Zalviso, including activities to address issues raised by the FDA during their regulatory review process, as well as activities associated with potential preparation for commercialization of Zalviso, should we receive approval from the FDA. In addition, we plan to continue to incur significant research and development expenses, including the expenses associated with the continued development of ARX-04. We do not plan to continue development of ARX-02 and ARX-03, unless additional funding or corporate partnership resources are available to support these programs.

 

 
69

 

 

We track external development expenses on a program-by-program basis. Our development resources are shared among all of our programs. Compensation and benefits, facilities, depreciation, stock-based compensation, and development support services are not allocated specifically to projects and are considered research and development overhead. Below is a summary of our research and development expenses during the years ended December 31, 2014, 2013 and 2012
(in thousands):

Due to the inherently unpredictable nature of product development, development timelines and the probability of success, development costs can differ materially from expectations. While we are currently focused on advancing Zalviso and the continued development of ARX-04, our future research and development expenses will depend on the clinical success of each product candidate as well as ongoing assessments of the commercial potential of our product candidates. In addition, we cannot predict which product candidates may be subject to future collaborations, when these arrangements will be secured, if at all, and to what degree these arrangements would affect our development plans and capital requirements.

 

Total research and development expenses for years ended December 31, 2014, 2013 and 2012 were as follows (in thousands, except percentages):

The $1.8 million decrease in research and development expenses during the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily attributable to a $5.4 million decrease related to our Zalviso Phase 3 clinical program conducted primarily in 2013, partially offset by an increase of $1.1 million related to our ARX-04 development program as we prepared for the Phase 3 clinical program and an increase of $2.5 million in overhead expenses, primarily due to increased personnel-related expenses, including stock-based compensation, primarily related to an increase in headcount to support continued development of Zalviso and ARX-04.

 

The $1.4 million increase during the year ended December 31, 2013, as compared to the year ended December 31, 2012, was primarily attributable to an increase of $2.1 million in headcount-related expenses, including bonus and stock-based compensation, due to an increase in headcount and a rising stock price, which created higher stock-based compensation expense. In addition, expenses related to ARX-04 increased $0.4 million due primarily to Phase 2 clinical trial expenses, which was completed in February 2013, and ongoing pharmaceutical development work. These increases were partially offset by a $1.1 million decrease in expenses related to our Zalviso development program, as we had completed one of the three Phase 3 trials in 2012 and completed the second and third Phase 3 trials, which were initiated in 2012, by mid-2013.

 

 

General and Administrative Expenses

 

General and administrative expenses consisted primarily of salaries, benefits and stock-based compensation for personnel in administration, finance, marketing and business development activities. Other significant expenses included legal expenses to pursue patent protection of our intellectual property, allocated facility costs and professional fees for general legal, audit and consulting services. We expect general and administrative expenses to continue to increase as we continue to build our corporate infrastructure in support of a pre-commercial organization and continue the development of our product candidates.

The $8.5 million increase in general and administrative expenses during the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily due to a $3.7 million increase in market research and use of outside services, primarily related to market research activities for Zalviso, and an increase of $4.8 million, primarily in headcount-related expenses, including recruiting efforts, to support organizational growth for the potential commercialization of Zalviso, and consulting and other professional services fees.

 

The $2.7 million increase during the year ended December 31, 2013 was primarily due to an increase in consulting/outside services of $1.4 million, primarily related to market research activities for Zalviso, an increase of $1.1 million in headcount-related expenses, primarily due to stock-based compensation expense as a result of an increasing stock price, and other corporate-related expenses.

 

Interest Expense

 

Interest expense consisted primarily of interest accrued or paid on our debt obligation agreements and amortization of debt discounts. Total interest expense for the years ended December 31, 2014, 2013 and 2012 was as follows (in thousands,

The $1.1 million increase in interest expense pertains to interest on our Amended Loan Agreement with Hercules, entered into in December 2013, which amended and restated the Original Loan Agreement. The overall debt facility was increased from $20 million to $40.0 million, $25.0 million of which was outstanding as of December 31, 2014, and the maturity was extended to October 1, 2017. On June 16, 2014, we borrowed the second tranche of $10.0 million. As a result, the amount of interest expense incurred during the year ended December 31, 2014, increased significantly as compared to the year ended December 31, 2013.

 

The $0.8 million decrease in interest expense during the year ended December 31, 2013, as compared to the year ended December 31, 2012, was due to a lower portion of our monthly payments attributable to interest due to the continued maturity of our Original Loan Agreement with Hercules, which was scheduled to mature on December 1, 2014. As mentioned above, the loan agreement was amended with Hercules in December 2013. In December 2013, we drew the first tranche of $15.0 million and used a portion of the proceeds to pay down the remaining principal and accrued interest on the Original Loan Agreement with Hercules, which was $8.6 million.

 

Interest and other income (expense), net

 

Interest income and other income (expense), net, during the years ended December 31, 2014, 2013 and 2012 consisted primarily of the change in the fair value of our warrants, or PIPE warrants, issued in connection with our private placement of our common stock, which was completed in June 2012. During the year ended December 31, 2013, we also recorded a loss of $1.2 million associated with extinguishment of our original loan agreement with Hercules, which we entered into in 2011, and amended in December 2013. Total interest income and other income (expense), net for the years ended December 31, 2014, 2013 and 2012 was as follows (in thousands, except percentages):

  $ 6,935     $ (15,241 )   $ (1,367 )   $ (22,176 )   $ 13,874  

 

The decrease in interest income and other income (expense), net, during the year ended December 31, 2014, as compared to the year ended December 31, 2013, of $22.2 million was primarily attributable to fewer PIPE warrants outstanding at December 31, 2014, compared to December 31, 2013, and a decrease in our stock price during the year ended December 31, 2014 as compared to a significant increase in our stock price during the year ended December 31, 2013, which is the primary driver in the Black-Scholes valuation model used to estimate the fair value of the PIPE warrants.

  

 
71

 

 

The $13.9 million increase in interest and other income (expense), net, during the year ended December 31, 2013 was primarily attributable to the increase in the fair value of our PIPE warrants, which was recorded as an expense. The primary determinant of this expense was an increase in share price during 2013 and its resulting impact on the Black-Scholes valuation of these warrants. In addition, we recorded a $1.2 million loss related to entering into the Amended Loan Agreement with Hercules. This transaction, under generally accepted accounting principles, was considered an extinguishment of the original Hercules debt arrangement.

 

Liquidity and Capital Resources

 

Liquidity

 

We have incurred losses and generated negative cash flows from operations since inception. We expect to continue to incur significant losses and negative cash flows in 2014 and may incur significant losses and negative cash flows for the foreseeable future. We have funded our operations primarily through the issuance of equity securities and debt financings, and more recently through our collaboration agreement with Grünenthal, which we entered into in December 2013.

 

As of December 31, 2014, we had cash, cash equivalents and investments totaling $75.4 million compared to $103.7 million as of December 31, 2013. The decrease was primarily attributable to cash required to fund our continuing operations, as we continue our research, development and pre-commercialization activities. We anticipate that our existing capital resources will permit us to meet our capital and operational requirements through at least the first quarter of 2016, excluding any potential proceeds from sales or milestones associated with our collaboration with Grünenthal, additional financings or other corporate partnerships. While we believe we have sufficient capital to meet our operational requirements through at least the first quarter of 2016, our expectations may change depending on a number of factors. For example, based on potential future discussion with the FDA regarding an additional clinical study for Zalviso, the FDA may indicate a scope or design of clinical trial that is beyond what our current and estimated future capital resources can support. In addition, completion of the ARX-04 development program is contingent on future funding from the DoD. We do have sufficient resources to initiate and complete our pivotal Phase 3 trial for ARX-04 and we intend to initiate this trial by the end of the quarter ending March 31, 2015. Our existing capital resources may not be sufficient to fund our operations until such time as we may be able to generate sufficient revenues to sustain our operations.

 

In December 2013, we announced a commercial collaboration with Grünenthal, covering the territory of the European Union, certain other European countries and Australia for Zalviso for potential use in pain treatment within or dispensed by a hospital, hospice, nursing home or other medically supervised setting. We retain all rights in remaining countries, including the United States, Asia and Latin America. Under the terms of the agreement, we received an upfront cash payment of $30.0 million, and a milestone payment of $5.0 million related to the MAA submission, which occurred in July 2014. We are eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA. If approved, we are eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts and net sales target achievements.  Grünenthal will also make tiered royalty, supply and trademark fee payments in the mid-teens up to the mid-twenties percent range, on net sales of Zalviso in the Grünenthal territory.

 

In December 2013, we entered into an amended loan and security agreement, or the Amended Loan Agreement, with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., collectively referred to as Hercules, under which we may borrow up to $40.0 million in three tranches, represented by secured convertible promissory notes. The agreement amends and restates the loan and security agreement with Hercules dated as of June 29, 2011, or the Original Loan Agreement. We borrowed the first tranche of $15.0 million upon closing of the transaction on December 16, 2013 and used approximately $8.6 million of the proceeds from the first tranche to repay our obligations under the Original Loan Agreement with Hercules. On June 16, 2014, we borrowed the second tranche of $10.0 million, which we plan to provide additional funding for the commercialization of Zalviso, as a potential source of funding for clinical trials for other development programs in our pipeline and for general corporate purposes. On September 24, 2014, we entered into an amendment, or the Amendment, to the Amended Loan Agreement with Hercules. The Amendment extends the time period under which we can draw down the third tranche, of up to $15.0 million, from March 15, 2015 to August 1, 2015, subject to obtaining approval for Zalviso from the FDA. We do not believe we will receive FDA approval of Zalviso by August 1, 2015 and as such, will not have access to the third tranche under the current agreement.

 

Our cash and investment balances are held in a variety of interest bearing instruments, including obligations of U.S. government agencies, money market funds and time deposits. Cash in excess of immediate requirements is invested with a view toward capital preservation and liquidity.

Cash Flows from Operating Activities

 

The primary use of cash for our operating activities during these periods was to fund the development of our product candidates, including commercial readiness activities for our lead product candidate, Zalviso. Our cash used for operating activities also reflected changes in our working capital and adjustments for non-cash charges, such as depreciation and amortization of our fixed assets, stock-based compensation, interest expense related to our debt financings and the revaluation of our PIPE warrant liability and the contingent put option liability.

 

Cash used in operating activities of $34.5 million during the year ended December 31, 2014, reflected a net loss of $33.4 million, partially offset by aggregate non-cash charges of $1.1 million. Non-cash charges included $4.4 million for stock-based compensation, partially offset by $7.0 million for the change in fair value of our PIPE warrant liability and contingent put liability.

 

Net cash used in operating activities of $0.5 million during the year ended December 31, 2013 reflected a net loss of $23.4 million, partially offset by aggregate non-cash charges of $20.0 million and a net change of $2.9 million in our net operating assets and liabilities. Non-cash charges primarily included $14.1 million for the revaluation of the PIPE warrant liability and the contingent put option liability, $3.5 million in stock-based compensation and $1.2 million for the loss on extinguishment of debt associated with our original loan agreement with Hercules, which was amended in December 2013. The net change in our operating assets and liabilities was primarily a result of an increase in deferred revenue of $2.6 million associated with our collaboration agreement with Grünenthal and a decrease in prepaid expenses of $1.1 million due to completion of our Phase 3 clinical trials for Zalviso in 2013.

 

Net cash used in operating activities of $24.6 million during the year ended December 31, 2012 reflected a net loss of $33.4 million, partially offset by aggregate non-cash charges of $5.3 million and a net change of $3.5 million in our net operating assets and liabilities. Non-cash charges primarily included $2.2 million in stock-based compensation and $1.4 million for the revaluation of the PIPE warrant liability and the contingent put option liability. The net change in our operating assets and liabilities was primarily a result of an increase in accounts payable and accrued liabilities of $2.7 million due to increased research and development activities during 2012.

 

Cash Flows from Investing Activities

 

Our investing activities have consisted primarily of our capital expenditures and purchases and sales and maturities of our available-for-sale investments.

 

During the year ended December 31, 2014, cash used in investing activities of $5.8 million was primarily as a result of $17.4 million for purchases of investments and $5.5 million for purchases of property and equipment, partially offset by $17.2 million in proceeds from maturity of investments.

 

During the year ended December 31, 2013, cash used in investing activities of $6.9 million was primarily a result of $28.0 million in purchases of investments and $3.3 million in purchases of property and equipment, partially offset by $24.4 million in maturities of investments.

 

During the year ended December 31, 2012, cash provided by investing activities of $15.0 million was primarily a result of $42.9 million in maturities of investments, partially offset by $27.2 million in purchases of investments and $0.8 million in purchases of property and equipment.

 

Cash Flows from Financing Activities

 

Cash flows from financing activities primarily reflect proceeds from the sale of our securities, proceeds from our debt financings and payments made on such debt financings. As of December 31, 2014, we had outstanding debt of $25.0 million, net of $0.1 million in unamortized debt discounts.

 

During the year ended December 31, 2014, cash provided by financing activities of $11.9 million was primarily due to the drawdown of the second tranche of the Hercules debt of $10.0 million.

  

 
73

 

 

During the year ended December 31, 2013, cash provided by financing activities was primarily a result of the receipt of $47.9 million in proceeds from an underwritten public offering in July 2013, net of offering costs and underwriting discounts, and proceeds of $15.0 million from our amended loan agreement with Hercules from December 2013, partially offset by payments of long-term debt of $16.3 million, including payment of the remaining principal of $8.5 million at the time of the amendment, and $7.8 million in principal payments made prior to the amendment.

 

During the year ended December 31, 2012, cash provided by financing activities was primarily a result of the receipt of $44.1 million in proceeds from an underwritten public offering in December 2012, net of offering costs and underwriting discounts, and proceeds of $9.1 million from a private placement of our common stock, in June 2012, net of offering costs. During the year ended December 31, 2012, we made payments of $3.7 million associated with our loan and security agreement
with Hercules.

 

Operating Capital and Capital Expenditure Requirements

 

We expect our rate of cash usage to increase in the future, in particular to support our product development activities, including continued development of Zalviso, ARX-04 and the potential commercialization of our product candidates, if approved. We anticipate that our existing capital resources will permit us to meet our capital and operational requirements through at least the first quarter of 2016. Our current operating plan includes the continued development of ARX-04, specifically initiation and completion of the pivotal Phase 3 clinical trial. These assumptions may change as a result of many factors. For example, we plan to meet with the FDA to understand the scope and design of the requested additional clinical study for Zalviso. The outcome of such discussion with the FDA will likely have a material impact to our operating spend. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. Additional capital may not be available on terms acceptable to us, or at all. If adequate funds are not available, or if the terms underlying potential funding sources are unfavorable, our business and our ability to develop our technology and product candidates would be harmed.

 

Our future capital requirements may vary materially from our expectations based on numerous forward looking factors, including but not limited to the following:

 

 

the outcome, timing and cost of regulatory approvals;

 

 

expenditures related to the activities required in support of our resubmission of the Zalviso NDA, including an additional clinical study for Zalviso;

 

 

expenditures related to our commercialization preparation of Zalviso;

 

 

future manufacturing, selling and marketing costs related to Zalviso, if the product candidate is approved for marketing, including our contractual obligations to Grünenthal;

 

 

the initiation, progress, timing and completion of clinical trials for our product candidates, including ARX-04;

 

 

changes in the focus and direction of our business strategy and/or research and development programs;

 

 

milestone and royalty revenue we receive under our collaborative development and commercialization arrangements;

 

 

delays that may be caused by changing regulatory requirements;

 

 

the number of product candidates that we pursue;

 

 

the initiation, progress, timing and completion of clinical trials for our product candidates and potential product candidates;

 

 

the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;

 

 

the timing and terms of future in-licensing and out-licensing transactions;

 

 

the cost and timing of establishing sales, marketing, manufacturing and distribution capabilities;

 

 

the cost of procuring clinical and commercial supplies of our product candidates;

 

 

 

the extent to which we acquire or invest in businesses, products or technologies; and

 

 

the expenses associated with the pending securities lawsuit, as well as any other litigation.

 

We will need substantial funds to:

 

 

commercialize any products we market, including Zalviso, if approved;

 

 

manufacture and market our product candidates;

 

 

conduct preclinical and clinical testing of our product candidates; and

 

 

conduct research and development programs.

  

 
74

 

 

Our existing capital resources may not be sufficient to fund our operations until such time as we may be able to generate sufficient revenues to sustain our operations. To the extent that our capital resources are insufficient to meet our future capital requirements, we will have to raise additional funds through the sale of our equity securities, monetization of current and future assets, issuance of debt or debt-like securities or from development and licensing arrangements to continue our development programs. We may be unable to raise such additional capital on favorable terms, or at all. If we raise additional capital by selling our equity or convertible debt securities, the issuance of such securities could result in dilution of our shareholders’ equity positions. If adequate funds are not available we may have to:

 

 

significantly curtail commercialization or development efforts of our product candidates or other operations;

 

 

obtain funds through entering into collaboration agreements on unattractive terms; and/or

 

 

delay, postpone or terminate planned clinical trials.

Patheon

 

In January 2013, we entered into a Services Agreement with Patheon Pharmaceuticals, Inc., or Patheon, relating to the manufacture of sufentanil sublingual tablets, for use with Zalviso. Under the terms of the Services Agreement, we have agreed to purchase, subject to Patheon’s continued material compliance with the terms of the Services Agreement, all of our sufentanil sublingual tablet requirements for the United States, Canada and Mexico from Patheon during the Initial Term of the Services Agreement (as defined below), and at least eighty percent (80%) of its sufentanil sublingual tablet requirements for such territories after the Initial Term. The term of the Services Agreement extends until December 31, 2017, or the Initial Term, and will automatically renew thereafter for periods of two years, unless terminated by either party upon eighteen months’ prior written notice; provided, however, that the Services Agreement may not be terminated without cause prior to the end of the Initial Term.

 

 

We also entered into an Amended and Restated Capital Agreement, or Amended Capital Agreement, with Patheon. Under the terms of the Amended Capital Agreement, we have the option to make certain future modifications to Patheon’s Cincinnati facility, which would be our responsibility. Under the Amended Capital Agreement, we made payments in 2012 and 2013 totaling $480,000 to Patheon to partially offset taxes incurred and paid by Patheon in connection with facility modifications already completed by Patheon. We can seek reimbursement from Patheon for these payments if we receive approval from the U.S. Food and Drug Administration for Zalviso. The Amended Capital Agreement further requires that we pay a maximum “overhead fee” of $200,000 annually during the term of the Services Agreement, which amount may be reduced to $0 based on the amount of annual revenues earned by Patheon under the Services Agreement and pre-existing development agreements with Patheon. No fee was due in 2013 or 2014 based on the amount of revenues earned by Patheon from AcelRx in 2013 and 2014.

 

Expenditures associated with the Services Agreement are primarily driven by the potential commercial requirements and demand for our products, none of which are currently approved for commercial use; accordingly, the amounts and timing of such future expenditures cannot be determined at this time.

 

Grünenthal

 

On December 16, 2013, AcelRx Grünenthal entered into a Collaboration and License Agreement, or the License Agreement, and related Manufacture and Supply Agreement, or the Manufacturing Agreement, and together with the License Agreement, the Agreements. The License Agreement grants Grünenthal rights to commercialize Zalviso, in the countries of the European Union, Switzerland, Liechtenstein, Iceland, Norway and Australia, or the Territory, for human use in pain treatment within or dispensed by hospitals hospices, nursing homes and other medically-supervised settings, or the Field.  

 

 
75

 

 

Under the terms of the Manufacturing Agreement, we will manufacture and supply Zalviso, or the Product, for use in the Field for the Territory exclusively for Grünenthal. Grünenthal shall purchase from us, during the first five years after the effective date of the Manufacturing Agreement, 100% and thereafter 80% of Grünenthal’s and its sublicensees’ and distributors’ requirements of Product for use in the Field for the Territory. The Product will be supplied at our fully burdened manufacturing cost (as defined in the Manufacturing Agreement). The Manufacturing Agreement requires us to use commercially reasonable efforts to enter stand-by contracts with third parties providing significant supply and manufacturing services and under certain specified conditions permits Grünenthal to use a third party back-up manufacturer to manufacture the Product for Grünenthal’s commercial sale in the Territory.

 

Unless earlier terminated, the Manufacturing Agreement continues in effect until the later of the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments or the end of any transition period for manufacturing obligations due to the expiration or termination of the License Agreement. The Manufacturing Agreement is subject to earlier termination in connection with certain termination events in the License Agreement, in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party or upon the bankruptcy or insolvency of either party.

 

Under the Supply Agreement, we will exclusively manufacture and supply the Product to Grünenthal for the Field in
the Territory.

 

Expenditures associated with the aforementioned agreements are primarily driven by the potential commercial requirements and demand for our products, and none of our product candidates are currently approved for commercial use; accordingly, the amounts and timing of such future expenditures cannot be determined at this time.

 

Off-Balance Sheet Arrangements

 

Through December 31, 2014, we have not entered into any off-balance sheet arrangements and do not have any holdings in variable interest entities.

 

 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

 

Our cash, cash equivalents and short-term investments as of December 31, 2014, consisted primarily of money market funds and U.S. government agency securities. We do not have any auction rate securities on our balance sheet, as they are not permitted by our investment policy. Our cash is invested in accordance with an investment policy approved by our board of directors which specifies the categories, allocations, and ratings of securities we may consider for investment. We do not believe our cash, cash equivalents and short-term investments have significant risk of default or illiquidity.

 

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because the majority of our investments are in short-term marketable debt securities. The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk. In an attempt to limit interest rate risk, we follow guidelines to limit the average and longest single maturity dates, place our investments with high quality issuers and follow internally developed guidelines to limit the amount of credit exposure to any one issuer. Some of the securities that we invest in may be subject to market risk. This means that a change in prevailing interest rates may cause the value of the investment to fluctuate. For example, if we purchase a security that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of our investment may decline. If a 10 percent change in interest rates were to have occurred on December 31, 2014, this change would not have had a material effect on the fair value of our investment portfolio as of that date. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate.

 

In addition, domestic and international equity markets have experienced and may continue to experience heightened volatility and turmoil based on domestic and international economic conditions and concerns. In the event these economic conditions and concerns continue and the markets continue to remain volatile, our results of operations could be adversely affected by those factors in many ways, including making it more difficult for us to raise funds if necessary and our stock price may further decline. In addition, we maintain significant amounts of cash and cash equivalents that are not federally insured. If economic instability continues, we cannot provide assurance that we will not experience losses on these investments.

Item 9A. Controls and Procedures

 

Evaluation of Disclosure Controls and Procedures

 

We have carried out an evaluation, under the supervision, and with the participation, of management including our principal executive officer and principal financial officer, of our disclosure controls and procedures (as defined in Rule 13a-15(e)) of the Securities Exchange Act of 1934, as amended, or the Exchange Act) as of the end of the period covered by this Annual Report on Form 10–K. Based on their evaluation, our principal executive officer and principal financial officer concluded that, subject to the limitations described below, our disclosure controls and procedures were effective as of December 31, 2014.

 

Limitations on the Effectiveness of Controls. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within an organization have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our principal executive officer and principal financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were sufficiently effective to provide reasonable assurance that the objectives of our disclosure control system were met. We continue to implement, improve and refine our disclosure controls and procedures and our internal control over financial reporting.

 

Changes in Internal Control over Financial Reporting

 

There have been no significant changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting during the fiscal quarter ended
December 31, 2014.

 

Management’s Annual Report on Internal Control over Financial Reporting

 

The following report is provided by management in respect of AcelRx Pharmaceuticals’ internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act):

 

1. AcelRx Pharmaceuticals’ management is responsible for establishing and maintaining adequate internal control over financial reporting.

 

2. AcelRx Pharmaceuticals management has used the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, framework (2013 framework) to evaluate the effectiveness of internal control over financial reporting. Management believes that the COSO framework is a suitable framework for its evaluation of financial reporting because it is free from bias, permits reasonably consistent qualitative and quantitative measurements of AcelRx Pharmaceuticals’ internal control over financial reporting, is sufficiently complete so that those relevant factors that would alter a conclusion about the effectiveness of AcelRx Pharmaceuticals’ internal control over financial reporting are not omitted and is relevant to an evaluation of internal control over financial reporting.

 

3. Management has assessed the effectiveness of AcelRx Pharmaceuticals’ internal control over financial reporting as of December 31, 2014 and has concluded that such internal control over financial reporting was effective.

 

Ernst & Young LLP, our independent registered public accounting firm, has attested to and issued a report on the effectiveness of our internal control over financial reporting, which is included herein.

Report of Independent Registered Public Accounting Firm 

 

The Board of Directors and Stockholders of AcelRx Pharmaceuticals, Inc.:

 

We have audited AcelRx Pharmaceuticals, Inc. internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). AcelRx Pharmaceuticals, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 

In our opinion, AcelRx Pharmaceuticals, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the COSO criteria.

 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the balance sheets of AcelRx Pharmaceuticals, Inc. as of December 31, 2014 and 2013, and the related statements of comprehensive loss, stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2014 of AcelRx Pharmaceuticals, Inc. and our report dated March 12, 2015 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm 

 

The Board of Directors and Stockholders

AcelRx Pharmaceuticals, Inc.

 

We have audited the accompanying balance sheets of AcelRx Pharmaceuticals, Inc. as of December 31, 2014 and 2013, and the related statements of comprehensive loss, stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

 

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of AcelRx Pharmaceuticals, Inc. at December 31, 2014 and 2013, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2014 in conformity with U.S. generally accepted accounting principles.

 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of AcelRx Pharmaceuticals, Inc. internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated March 12, 2015 expressed an unqualified opinion thereon.

1. Organization and Summary of Significant Accounting Policies

 

The Company

 

AcelRx Pharmaceuticals, Inc., or the Company or AcelRx, was incorporated in Delaware on July 13, 2005 as SuRx, Inc., and in January 2006, the Company changed its name to AcelRx Pharmaceuticals, Inc. The Company’s operations are based in Redwood City, California.

 

AcelRx is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain. AcelRx intends to commercialize its product candidates in the United States and license the development and commercialization rights to its product candidates for sale outside of the United States through strategic partnerships and collaborations. On July 25, 2014, the U.S. Food and Drug Administration, or FDA, issued a Complete Response Letter, or CRL, for the Company’s new drug application, or NDA, for Zalviso™ (sufentanil sublingual tablet system), formerly known as ARX-01. In March 2015, the Company announced the receipt of correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies it has performed, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. The proposed indication for Zalviso is for the management of moderate-to-severe acute pain in adult patients in the hospital setting. Zalviso consists of sufentanil sublingual tablets delivered by the Zalviso System, a needle-free, handheld, patient-administered, pain management system (together, “Zalviso”).

 

The Company has incurred recurring operating losses and negative cash flows from operating activities since inception and expects to continue to incur negative cash flows until its product candidates are approved for marketing in the United States and other countries, in which it has and intends to license its products, which may never occur. In previous years, prior to the completion of the clinical development program for Zalviso and the commercial collaboration of Zalviso, AcelRx was considered a development stage company.

 

The Company has one business activity, which is the development and commercialization of product candidates for the treatment of pain, and a single reporting and operating unit structure.

 

Basis of Presentation

 

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.

 

Use of Estimates

 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management evaluates its estimates on an ongoing basis including critical accounting policies. Estimates are based on historical experience and on various other market-specific and other relevant assumptions that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

 

Concentration of Risk

 

The Company invests cash that is currently not being used for operational purposes in accordance with its investment policy in debt securities of the U.S. Treasury and U.S. government sponsored agencies and overnight deposits. The Company is exposed to credit risk in the event of default by the institutions holding the cash equivalents and available-for-sale securities to the extent recorded on the balance sheet. Our cash and cash equivalent balances can be in excess of federally
insured amounts.

 

Cash, Cash Equivalents and Marketable Securities

 

The Company considers all highly liquid investments with an original maturity (at date of purchase) of three months or less to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks and money market instruments.

 

All marketable securities are classified as available-for-sale and consist of U.S. Treasury and U.S. government sponsored enterprise debt securities. These securities are carried at estimated fair value, which is based on quoted market prices or observable market inputs of almost identical assets, with unrealized gains and losses included in accumulated other comprehensive income (loss). The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion is included in interest income or expense. The cost of securities sold is based on specific identification. The Company’s investments are subject to a periodic impairment review for other-than-temporary declines in fair value. The Company’s review includes the consideration of the cause of the impairment including the creditworthiness of the security issuers, the number of securities in an unrealized loss position, the severity and duration of the unrealized losses and the Company’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value. When the Company determines that the decline in fair value of an investment is below its accounting basis and this decline is other-than-temporary, it reduces the carrying value of the security it holds and records a loss in the amount of such decline.

Notes to Financial Statements

 

Property and Equipment

 

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvements or the remaining lease term.

 

Impairment of Long-Lived Assets

 

The Company periodically assesses the impairment of long-lived assets and, if indicators of asset impairment exist, the Company assesses the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered through an analysis of the undiscounted future expected operating cash flows. If impairment is indicated, the Company records the amount of such impairment for the excess of the carrying value of the asset over its estimated fair value. For example, purchased equipment and manufacturing-related facility improvements the Company has made at Patheon’s facility in Ohio, are utilized for continued research and development, and potential commercial manufacturing of our product candidates. If the Company does not receive regulatory approval for our product candidates, the Company may determine that it is no longer probable that the Company will realize the future economic benefit associated with the costs of these assets through future manufacturing activities, and if so, the Company would record an impairment charge associated with these assets. As of December 31, 2014, the Company has not written down any of its long-lived assets as a result of impairment.

 

Restricted Cash

 

Under the Company’s facility lease and corporate credit card agreements, the Company is required to maintain letters of credit as security for performance under these agreements. The letters of credit are secured by certificates of deposit in amounts equal to the letters of credit, which are classified as restricted cash on the balance sheet.

 

Contingent put option

 

The contingent put option associated with the Company’s loan and security agreement with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., collectively referred to as Hercules, is recorded as a liability. Changes in the fair value of the contingent put option are recognized as interest income and other income (expense), net in the Statements of Comprehensive Loss. For additional information regarding the contingent put option, see Note 6 “Long Term Debt.”

 

Warrants

 

Warrants issued in connection with the Company’s Private Placement, completed in June 2012, are recorded as liabilities as they have the potential for cash settlement upon the occurrence of certain transactions (as defined in the warrant; see Note 7 “Warrants”). Changes in the fair value of the warrants are recognized as interest income and other income (expense), net in the Statements of Comprehensive Loss.

 

Revenue Recognition

 

The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the fee is fixed or determinable; and collectability is reasonably assured.

 

 

Collaboration Revenue

 

Collaboration revenue, which is earned under license agreements with third parties, may include nonrefundable license fees, cost reimbursements, research and development services, commercial manufacturing services, contingent development and commercial milestones and royalties.

Notes to Financial Statements

 

AcelRx accounts for multiple-element arrangements in accordance with ASC Topic 605-25, Revenue Recognition—Multiple-Element Arrangements, or ASC 605-25.The Company evaluates if the deliverables in the arrangement represent separate units of accounting. In determining the units of accounting, AcelRx evaluates certain criteria, including whether the deliverables have value to our customers on a stand-alone basis. Factors considered in this determination include whether the deliverable is proprietary to the Company, whether the customer can use the license or other deliverables for their intended purpose without the receipt of the remaining elements, whether the value of the deliverable is dependent on the undelivered items, and whether there are other vendors that can provide the undelivered items. Deliverables that meet these criteria are considered a separate unit of accounting. Deliverables that do not meet these criteria are combined and accounted for as a single unit of accounting.

 

For revenue agreements with multiple-element arrangements, such as the collaboration and license agreement with Grünenthal, the Company allocates revenue to each non-contingent element based on the relative selling price of each element. When applying the relative selling price method, the Company determines the selling price for each deliverable using vendor-specific objective evidence, or VSOE, of selling price or third-party evidence, or TPE, of selling price. If neither exists the Company uses best estimated selling price, or BESP, for that deliverable. Revenue allocated is then recognized when the four basic revenue recognition criteria are met for each element.

 

VSOE is based on the price charged when the element is sold separately and is the price actually charged for that deliverable. Establishing VSOE may not be possible for the elements of a license arrangement because each arrangement is unique, an arrangement typically consists of multiple elements and AcelRx has limited history of entering into license arrangements. When VSOE cannot be established, AcelRx attempts to establish the selling price of the elements of a license arrangement based on TPE. TPE is determined based on a competitor’s price for similar deliverables when sold separately. AcelRx may not be able to determine TPE for license arrangements, as they contain a significant level of differentiation such that the comparable pricing of a competitor’s license arrangement with similar functionality cannot be obtained, and AcelRx is therefore unable to reliably determine what a similar competitor’s license arrangement’s selling price would be on a standalone basis.

 

When AcelRx is unable to establish the selling price of an element using VSOE or TPE, BESP is utilized in the allocation of the elements of the arrangement. The objective of the BESP is to determine the price at which AcelRx would transact a sale if the element of the license arrangement were sold on a standalone basis.

 

The process for determining BESPs involves management’s judgment. AcelRx’ process considers multiple factors such as discounted cash flows, estimated direct expenses and other costs and available data, which may vary over time, depending upon the circumstances, and relate to each deliverable. If the estimated obligation period of one or more deliverables should change, the future amortization of the revenue would also change.

 

AcelRx recognizes a contingent milestone payment as revenue in its entirety upon our achievement of the milestone. A milestone is substantive if the consideration earned from the achievement of the milestone (i) is consistent with performance required to achieve the milestone or the increase in value to the delivered item, (ii) relates solely to past performance and (iii) is reasonable relative to all of the other deliverables and payments within the arrangement.

 

Research Grant Revenue

 

In May 2011, the Company entered into an award contract with the US Army Medical Research and Materiel Command, or USAMRMC, to support the development of the Company’s new product candidate, ARX-04, a sufentanil sublingual tablet for the treatment of moderate-to-severe acute pain. The grant provides for the reimbursement of qualified expenses for research and development activities as defined under the terms of the grant agreement. Revenue under the grant agreement is recognized when the related qualified research expenses are incurred.

 

Research and Development Expenses

 

Research and development costs are charged to expense when incurred. Research and development expenses include salaries, employee benefits, including stock-based compensation, consultant fees, laboratory supplies, costs associated with clinical trials and manufacturing, including contract research organization fees, other professional services and allocations of corporate costs. The Company reviews and accrues clinical trial expenses based on work performed, which relies on estimates of total costs incurred based on patient enrollment, completion of patient studies and other events.

Notes to Financial Statements

 

Comprehensive Loss

 

Comprehensive loss is comprised of net loss and other comprehensive income (loss) and is disclosed in the Statement of Comprehensive Loss. For the Company, other comprehensive income (loss) consists of changes in unrealized gains and losses on the Company’s investments.

 

Fair Value of Financial Instruments

 

The Company measures and reports its cash equivalents, investments and financial liabilities at fair value. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

 

Level I—Unadjusted quoted prices in active markets for identical assets or liabilities;

 

Level II—Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

 

Level III—Unobservable inputs that are supported by little or no market activity for the related assets or liabilities.

 

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

 

 

Income Taxes

 

Deferred tax assets and liabilities are measured based on differences between the financial reporting and tax basis of assets and liabilities using enacted rates and laws that are expected to be in effect when the differences are expected to reverse. The Company records a valuation allowance for the full amount of deferred assets, which would otherwise be recorded for tax benefits relating to operating loss and tax credit carryforwards, as realization of such deferred tax assets cannot be determined to be more likely than not.

 

Stock-Based Compensation

 

Compensation expense for all share-based payment awards made to employees and directors, including employee stock options, restricted stock units and employee share purchases related to the 2011 Employee Stock Purchase Plan, or ESPP, is based on estimated fair values at grant date. The Company determines the grant date fair value of the awards using the Black-Scholes option-pricing model and generally recognizes the fair value as stock-based compensation expense on a straight-line basis over the vesting period of the respective awards.

 

The Black-Scholes option pricing model requires inputs such as expected term, expected volatility and risk-free interest rate. These inputs are subjective and generally require significant analysis and judgment to develop. Estimates of expected life are primarily determined using the simplified method in accordance with guidance provided by the SEC. Such method was utilized as the Company did not believe its historical option exercise experience, which was limited, provided a reasonable basis upon which to estimate expected term. Volatility is derived from historical volatilities of several public companies within AcelRx’s industry that are deemed to be comparable to AcelRx’s business because AcelRx’s has insufficient history on the volatility of its common stock relative to the expected life assumptions used by the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected life assumption. Further, the Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.

 

Net Loss per Share of Common Stock

 

The Company’s basic net loss per share of common stock is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. The diluted net loss per share of common stock is computed by giving effect to all potential common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of this calculation, convertible preferred stock, options to purchase common stock, restricted stock subject to repurchase, warrants to purchase convertible preferred stock and warrants to purchase common stock were considered to be common stock equivalents. In periods with a reported net loss, such common stock equivalents are excluded from the calculation of diluted net loss per share of common stock if their effect is antidilutive. For additional information regarding the net loss per share, see Note 11 “Net Loss per Share of Common Stock.”

Recently Issued Accounting Pronouncements 

 

In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 will explicitly require management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for AcelRx beginning in fiscal 2017. Earlier adoption is permitted. The Company is currently evaluating the potential impact of the adoption of ASU 2014-15.

 

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, issued as a new Topic, Accounting Standards Codification (ASC) Topic 606.  The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a Company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is effective for AcelRx beginning in fiscal 2017 and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption.  The Company is currently evaluating the effect that adopting this new accounting guidance will have on its results of operations, cash flows and financial position.

 

2. Investments and Fair Value Measurement

 

Investments

 

The Company classifies its marketable securities as available-for-sale and records its investments at fair value. Available-for-sale securities are carried at estimated fair value based on quoted market prices or observable market inputs of almost identical assets, with the unrealized holding gains and losses included in accumulated other comprehensive income. Marketable securities which have maturities beyond one year as of the end of the reporting period are classified as non-current.

 Fair Value Measurement

 

The Company’s financial instruments consist of Level I and Level II assets and Level III liabilities. Level I securities include highly liquid money market funds and are valued based on quoted market prices. For Level II instruments, the Company estimates fair value by utilizing third party pricing services in developing fair value measurements where fair value is based on valuation methodologies such as models using observable market inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers and other reference data. Such Level II instruments typically include U.S. treasury and U.S. government agency obligations. As of December 31, 2014 and December 31, 2013, the Company held, in addition to Level I and Level II assets, a contingent put option liability associated with the Company’s loan and security agreement with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., collectively referred to as Hercules, which was classified as a Level III liability. The Company’s estimate of fair value of the contingent put option liability was determined by using a risk-neutral valuation model, wherein the fair value of the underlying debt facility is estimated both with and without the presence of the default provisions, holding all other assumptions constant. The resulting difference between the two estimated fair values is the estimated fair value of the default provisions, or the contingent put option. The fair value of the underlying debt facility is estimated by calculating the expected cash flows in consideration of an estimated probability of default and expected recovery rate in default, and discounting such cash flows back to the reporting date using a risk-free rate. As of December 31, 2014 and 2013, the Company also held a Level III liability associated with warrants, or PIPE warrants, issued in connection with the Company’s private placement equity offering, completed in June 2012. For a detailed description, see Note 9 “Stockholders’ Equity.” The PIPE warrants are considered a liability and are valued using the Black-Scholes option-pricing model, the inputs for which include exercise price of the PIPE warrants, market price of the underlying common shares, expected term, volatility based on a group of the Company’s peers and the risk-free rate corresponding to the expected term of the PIPE warrants. Changes to any of these inputs can have a significant impact to the estimated fair value of the PIPE warrants.

4. Research Grant

 

In May 2011, AcelRx received a grant from the US Army Medical Research and Materiel Command, or USAMRMC, in which the USAMRMC granted $5.6 million to the Company in order to support the development of a new product candidate, ARX-04, a sufentanil sublingual tablet for the treatment of moderate-to-severe acute pain. Under the terms of the grant, the USAMRMC will reimburse the Company for development, manufacturing and clinical costs necessary to prepare for and complete the planned Phase 2 dose-finding trial in a study of acute moderate-to-severe pain, and to prepare to enter Phase 3 development. The grant gives the USAMRMC the option to extend the term of the grant and provide additional funding for the research. As of December 31, 2013, the full amount of the grant, $5.6 million, had been recognized as revenue.

 

Revenue is recognized based on expenses incurred by AcelRx in conducting research and development activities set forth in the agreement. Revenue attributable to the research and development performed under the USAMRMC grant was $0, $2.1 million and $2.4 million for the years ended December 31, 2014, 2013, and 2012, respectively.

 

5. Collaboration

 

On December 16, 2013, AcelRx and Grünenthal GmbH, or Grünenthal, entered into a Collaboration and License Agreement, or the License Agreement, and related Manufacture and Supply Agreement, or the Manufacturing Agreement, and together with the License Agreement, or the Agreements. The License Agreement grants Grünenthal rights to commercialize Zalviso the Company’s novel sublingual patient-controlled analgesia, or PCA, system, or the Product, in the countries of the European Union, Switzerland, Liechtenstein, Iceland, Norway and Australia, or the Territory, for human use in pain treatment within or dispensed by hospitals hospices, nursing homes and other medically-supervised settings, or the Field. The Company retains rights with respect to the Product in countries outside the Territory, including the United States, Asia and Latin America. Under the Supply Agreement, the Company will exclusively manufacture and supply the Product to Grünenthal for the Field in the Territory.

 

License Agreement

 

Under the terms of the License Agreement, Grünenthal has the exclusive right to commercialize the Product in the Field in the Territory. The Company retains control of clinical development, while Grünenthal and the Company will be responsible for certain development activities pursuant to a development plan as agreed between the parties. The Company will not receive separate payment for such development activities. Grünenthal is exclusively responsible for marketing approval applications and other regulatory filings relating to the sufentanil sublingual tablet drug cartridge for the Product in the Field in the Territory, while the Company is responsible for the CE Mark and other regulatory filings relating to device portions of the Product. A CE Mark (#611742) for Zalviso was obtained in the fourth quarter 2014 which specifies AcelRx as the device design authority and manufacturer.

 

The Company received an upfront non-refundable cash payment of $30.0 million in December 2013, and a milestone payment of $5.0 million related to the MAA submission in the third quarter of 2014. The Company is eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA, if approved. If the MAA is approved, the Company is eligible to receive approximately $200.0 million in additional milestone payments, based upon successful regulatory and product development efforts ($28.5 million) and net sales target achievements ($171.5 million). Grünenthal will also make tiered royalty and supply and trademark fee payments in the mid-teens up to the mid-twenties percent range on net sales of Zalviso.

 

Unless earlier terminated, the License Agreement continues in effect until the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments, which supply and trademark fee continues for so long as the Company continues to supply the Product to Grünenthal. The License Agreement is subject to earlier termination in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party, upon the bankruptcy or insolvency of either party, or by Grünenthal for convenience.

 

 

Manufacturing Agreement

 

Under the terms of the Manufacturing Agreement, the Company will manufacture and supply the Product for use in the Field for the Territory exclusively for Grünenthal. Grünenthal shall purchase from AcelRx, during the first five years after the effective date of the Manufacturing Agreement, 100% and thereafter 80% of Grünenthal’s and its sublicensees’ and distributors’ requirements of Product for use in the Field for the Territory. The Product will be supplied at the Company’s fully burdened manufacturing cost (as defined in the Manufacturing Agreement). The Manufacturing Agreement requires the Company to use commercially reasonable efforts to enter stand-by contracts with third parties providing significant supply and manufacturing services and under certain specified conditions permits Grünenthal to use a third party back-up manufacturer to manufacture the Product for Grünenthal’s commercial sale in the Territory.

AcelRx Pharmaceuticals, Inc.

 

Notes to Financial Statements

 

Unless earlier terminated, the Manufacturing Agreement continues in effect until the later of the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments or the end of any transition period for manufacturing obligations due to the expiration or termination of the License Agreement. The Manufacturing Agreement is subject to earlier termination in connection with certain termination events in the License Agreement, in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party or upon the bankruptcy or insolvency of either party.

 

The Company identified the following four significant non-contingent performance deliverables under the agreements: 1) intellectual property (license), 2) the obligation to provide research and development services, 3) the significant and incremental discount on the manufacturing of Zalviso for commercial purposes, and 4) the obligation to participate on the joint steering committee.

 

The Company considered the provisions of the multiple-element arrangement guidance in determining whether the deliverables outlined above have standalone value and thus should be treated as separate units of accounting. Company’s management determined that the license has standalone value and represents a separate unit of accounting because the rights conveyed permit Grünenthal to perform all efforts necessary to commercialize and begin selling the product upon regulatory approval. In addition, Grünenthal has the appropriate development, regulatory and commercial expertise with products similar to the product licensed under the agreement and has the ability to engage third parties to manufacture the product allowing Grünenthal to realize the value of the license without receiving any of the remaining deliverables. Grünenthal can also sublicense its license rights to third parties. Also, the Company’s management determined that the research services, committee participation and implied discount associated with the manufacturing services each represent individual units of accounting as Grünenthal could perform such services and/or could acquire these on a separate basis.

 

The Company developed best estimates of selling prices for each deliverable in order to allocate the noncontingent arrangement consideration to the four units of accounting.

 

The Company’s management determined the best estimate of selling price for the license based on Grünenthal’s estimated future cash flows arising from the arrangement. Embedded in the estimate were significant assumptions regarding regulatory expenses, revenue, including potential customer market for the product and product price, costs to manufacture the product and the discount rate. The Company’s management determined the best estimate of selling price of the research and development services and committee participation based on the nature and timing of the services to be performed and in consideration of personnel and other costs incurred in the delivery of the services. For the discount on manufacturing services, Company’s management estimated the selling price based on the market level of contract manufacturing margin it could have received if it were engaged to supply products to a customer in a separate transaction.

 

 

The Agreements entitle the Company to receive additional payments upon the achievement of certain development and sales milestones. Based on ASC Topic 605-28, Revenue Recognition — Milestone Method, the Company evaluates contingent milestones at inception of the agreement, and recognizes consideration that is contingent upon the achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone is considered substantive in its entirety. Milestones are events which have the following characteristics: (i) they can be achieved based in whole or in part on either the Company’s performance or on the occurrence of a specific outcome resulting from the Company’s performance, (ii) there was substantive uncertainty at the date the agreement was entered into that the event would be achieved and, (iii) they would result in additional payments due to the Company. A milestone is considered substantive if the following criteria are met: (i) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, or (2) the enhancement of the value of the delivered item (s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone, (ii) the consideration relates solely to past performance and, (iii) the consideration is reasonable relative to all of the other deliverables and payment terms, including other potential milestone consideration, within
the arrangement.

 

The substantive milestone payments will be recognized as revenue in their entirety upon the achievement of each substantive milestone. Based on the criteria noted above, the identified substantive milestones in the agreement pertain to post approval product enhancements, expanded market opportunities and manufacturing efficiencies for Zalviso. Each of these potential achievements is based primarily on the Company’s performance and involves substantive uncertainty as achievement of these milestones require future research, development and regulatory activities, which are inherently uncertain in nature. The Company determined that the consideration for each milestone was commensurate with the Company’s performance to achieve the milestone, including future research, development, manufacturing and regulatory activities and that the consideration is reasonable relative to all of the other deliverables and payments within the arrangement. Aggregate potential payments for these milestones total $28.5 million.

Notes to Financial Statements

 

In addition to substantive milestones, two milestones associated with the Agreements were deemed not to be substantive. These milestones pertain to regulatory developments for Zalviso in Europe, which Company’s management deemed to be not substantive due to the level of performance associated with future achievement of these milestones. Aggregate potential payments for these milestones total $20.0 million. In July 2014, Grünenthal submitted a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA, for Zalviso for the management of moderate-to-severe acute pain in adult patients in a medically supervised environment. Under the terms of the License Agreement with Grünenthal, the Company received a cash payment of $5.0 million for the MAA submission in the third quarter of 2014. The Company is eligible to receive an additional $15.0 million milestone payment upon the approval of the MAA.

 

The Agreements also include milestone payments related to specified net sales targets, totaling $171.5 million. The sales-based milestones do not meet the definition of a milestone under ASU 2010-17 because the achievement of these milestones is solely dependent on counter-party performance and not on any performance obligations of the Company.

 

The Company allocated the $30.0 million upfront fee across the four deliverables based on estimated selling prices and during the year ended December 31, 2013, recognized $27.4 million attributable to the license. As mentioned above, the Company received a milestone payment of $5.0 million related to the MAA submission, of which $4.6 million was recognized during the year ended December 31, 2014. In addition, the Company recognized $0.6 million of previously deferred revenue related to research and development services and its obligation to participate in the joint steering committee under the collaboration agreement during the year ended December 31, 2014. As of December 31, 2014, the Company had a deferred revenue balance of $2.4 million. There were no other milestone payments received or recognized under these Agreements during the year ended December 31, 2014.

 

 

6. Long-Term Debt

 

Hercules Loan and Security Agreements

 

In June 2011, AcelRx entered into a loan and security agreement with Hercules, under which AcelRx borrowed $20.0 million in two tranches of $10.0 million each, represented by secured convertible term promissory notes. The Company’s obligations associated with the agreement are secured by a security interest in substantially all of its assets, other than its
intellectual property.

 

The Company borrowed the first tranche of $10.0 million upon the closing of the transaction on June 29, 2011 and borrowed the second tranche of $10.0 million in December 2011. The Company used a portion of the proceeds from the first tranche to repay the remaining obligations under that certain loan and security agreement between the Company and Pinnacle Ventures, L.L.C., or Pinnacle Ventures, dated September 16, 2008. The agreement with Pinnacle Ventures is described further below. The interest rate for each tranche was 8.50%. In connection with the loan, the Company issued Hercules seven-year warrants to purchase an aggregate of 274,508 shares of common stock at a price of $3.06 per share. See Note 7 “Warrants,” for
further description.

 

On December 16, 2013, AcelRx entered into an Amended and Restated Loan and Security Agreement, or the Loan Agreement with Hercules Technology II, L.P. and Hercules Technology Growth Capital, Inc., together, the Lenders, under which the Company may borrow up to $40.0 million in three tranches. The loans are represented by secured convertible term promissory notes, collectively, the Notes. The Loan Agreement amends and restates the Loan and Security Agreement between the Company and the Lenders dated as of June 29, 2011, or the Original Loan Agreement, as noted above. The Company borrowed the first tranche of $15.0 million upon closing of the transaction on December 16, 2013, and the second tranche of $10.0 million on June 16, 2014. The Company used approximately $8.6 million of the proceeds from the first tranche to repay its obligations under the Original Loan Agreement. The Company recorded the new debt at an estimated fair value of $24.9 million and $14.3 million as of December 31, 2014 and December 31, 2013, respectively.

Notes to Financial Statements

 

In accordance with ASC Topic No. 470, “Debt – Modifications and Extinguishments” (Topic No. 470), the amendment noted above was determined to be an extinguishment of the existing debt and an issuance of new debt. The Company reached this conclusion based on a comparison of discounted remaining cash flows of the original loan agreement compared to the amended loan agreement, the result of which was a greater than 10% difference in discounted cash flows. The Company determined this difference to be significant and recorded the new debt at estimated fair value.

 

As a result of the extinguishment, the Company recorded a $1.2 million loss on extinguishment of debt which was recorded as interest income and other income (expense), net on the Statements of Comprehensive Loss during the year ended December 31, 2013. The loss on extinguishment was a non-cash write off, consisting of deferred debt charges, the unamortized portion of the original issue discount related to the Original Loan Agreement and other fees associated with extinguishing the debt, including the estimated fair value of warrants issued in connection with the amended loan agreement, facility and legal fees associated with the amended loan agreement and the value of the contingent put option liability associated with the original loan agreement at the time of the amendment.

 

On September 24, 2014, the Company entered into an amendment, or the Amendment, to the Amended Loan Agreement with Hercules. The Amendment extends the time period under which the Company can draw down the third tranche, of up to $15.0 million, from March 15, 2015 to August 1, 2015, subject to the Company obtaining approval for Zalviso from the U.S. Food and Drug Administration. The Company does not believe it will receive FDA approval of Zalviso by August 1, 2015 and as such, will not have access to the third tranche under the current agreement.

 

The interest rate for each tranche will be calculated at a rate equal to the greater of either (i) 9.10% plus the prime rate as reported from time to time in The Wall Street Journal minus 5.25%, and (ii) 9.10%. Payments under the Amended Loan Agreement are interest only until April 1, 2015 followed by equal monthly payments of principal and interest through the scheduled maturity date on October 1, 2017, or the Loan Maturity Date. In addition, a final payment equal to $1.7 million will be due on the Loan Maturity Date, or such earlier date specified in the Amended Loan Agreement. The Company’s obligations under the Amended Loan Agreement are secured by a security interest in substantially all of its assets, other than its intellectual property.

 

If the Company prepays the Amended Loan Agreement prior to maturity, it will pay Hercules a prepayment charge, based on a percentage of the then outstanding principal balance, equal to 3% if the prepayment occurs prior to December 16, 2014, 2% if the prepayment occurs after December 16, 2014, but prior to December 16, 2015, or 1% if the prepayment occurs after December 16, 2015.

 

Subject to certain conditions and limitations set forth in the Amended Loan Agreement, the Company has the right to convert up to $5.0 million of scheduled principal installments under the Notes into freely tradeable shares of the Company’s common stock, or Common Stock. The number of shares of Common Stock that would be issued upon conversion of the Amended Notes would be equal to the number determined by dividing (x) the product of (A) the principal amount to be paid in shares of Common Stock and (B) 103%, by (y) $9.30 (subject to certain proportional adjustments as provided for in the Amended Loan Agreement).

 

The Amended Loan Agreement includes customary affirmative and restrictive covenants, but does not include any financial maintenance covenants, and also includes standard events of default, including payment defaults, breaches of covenants following any applicable cure period, a material impairment in the perfection or priority of Hercules’ security interest or in the value of the collateral, and events relating to bankruptcy or insolvency. Upon the occurrence of an event of default, a default interest rate of an additional 5% may be applied to the outstanding loan balances, and Hercules may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Amended Loan Agreement.

 

In connection with the Amended Loan Agreement, the Company issued a warrant to each Lender which, collectively, are exercisable for an aggregate of 176,730 shares of common stock and each carry an exercise price of $6.79 per share. See Note 7 “Warrants,” for further description.

 

Upon an event of default, including a change of control, Hercules has the option to accelerate repayment of the Amended Loan Agreement, including payment of any applicable prepayment charges, which range from 1%-3% of the outstanding loan balance and accrued interest, as well as a final payment fee of $1.7 million. This option is considered a contingent put option liability, as the holder of the loan may exercise the option in the event of default, and is considered an embedded derivative, which must be valued and separately accounted for in the Company’s financial statements. As the amendment of the loan agreement was considered an extinguishment, the contingent put option liability associated with the Original Loan Agreement, which had an estimated fair value of $32,000 at the time of the amendment, was written off as a part of the loss on extinguishment, and a new contingent put option liability was established. As of December 31, 2014 and December 31, 2013, the estimated fair value of the contingent put option liability was $282,000 and $334,000, respectively, which was determined by using a risk-neutral valuation model, wherein the fair value of the underlying debt facility is estimated both with and without the presence of the default provisions, holding all other assumptions constant. The resulting difference between the two estimated fair values is the estimated fair value of the default provisions, or the contingent put option. The fair value of the underlying debt facility is estimated by calculating the expected cash flows in consideration of an estimated probability of default and expected recovery rate in default, and discounting such cash flows back to the reporting date using a risk-free rate. The contingent put option liability was recorded as a debt discount to the loan and consequently a reduction to the carrying value of the loan. The contingent put option liability is revalued at the end of each reporting period and any change in the fair value is recognized in interest income and other income (expense), net in the Statements of Comprehensive Loss.

In February 2013, warrants to purchase 228,264 shares were net exercised, for 58,580 shares of common stock. As of December 31, 2014, no warrants to purchase shares of common stock issued to Pinnacle were outstanding.

 

Hercules Warrants

 

In connection with the Amended Loan Agreement, executed in December 2013, the Company issued warrants to Hercules which are exercisable for an aggregate of 176,730 shares of common stock with an exercise price of $6.79 per share (the “Warrants”). Each Warrant may be exercised on a cashless basis. The Warrants are exercisable for a term beginning on the date of issuance and ending on the earlier to occur of five years from the date of issuance or the consummation of certain acquisitions of the Company as set forth in the Warrants. The number of shares for which the Warrants are exercisable and the associated exercise price are subject to certain proportional adjustments as set forth in the Warrants. The Company estimated the fair value of these warrants as of the issuance date to be $1.1 million, which was used in the estimating the fair value of the amended debt instrument and was recorded as equity. The fair value of the warrants was calculated using the Black-Scholes option-valuation model, and was based on the strike price of $6.79, the stock price at issuance of $9.67, the five-year contractual term of the warrants, a risk-free interest rate of 1.55%, expected volatility of 71% and 0% expected dividend yield.

The per share exercise price of the PIPE warrants was $3.40 which equals the closing consolidated bid price of the Company’s common stock on May 29, 2012, the effective date of the Purchase Agreement. The PIPE warrants issued in the Private Placement became exercisable six months after the issuance date, and expire on the five year anniversary of the initial exercisability date. Under the terms of the PIPE warrants, upon certain transactions, including a merger, tender offer, sale of all or substantially all of the assets of the Company or if a person or group shall become the owner of 50% of the Company’s issued and outstanding common stock, which is outside of the Company’s control, each PIPE warrant holder may elect to receive a cash payment in exchange for the warrant, in an amount determined by application of the Black-Scholes option-pricing model. Accordingly, the PIPE warrants were recorded as a liability at fair value, as determined by the Black-Scholes option-pricing model, and then marked to fair value each reporting period, with changes in estimated fair value recorded through the Statements of Comprehensive Loss in interest income and other income (expense), net. The Black-Scholes assumptions used to value the PIPE warrants are disclosed in Note 2 “Investments and Fair Value Measurement.”

 

Upon execution of the Purchase Agreement, the fair value of the PIPE warrants was estimated to be $5.8 million, which was recorded as a liability. As of December 31, 2014, the fair value of the PIPE warrants was estimated to be $5.6 million. The change in fair value for the year ended December 31, 2014, which was recorded as other income, was $7.0 million. The change in fair value for the year ended December 31, 2013, which was recorded as other expense, was $14.1 million.

 

During the year ended December 31, 2014, PIPE warrants to purchase 135,000 shares were net exercised for 91,488 shares of common stock. During the year ended December 31, 2013, warrants to purchase 1,135,589 shares were net exercised, for 808,078 shares of common stock. As of December 31, 2014, PIPE warrants to purchase 1,359,514 shares of common stock issued in connection with the Private Placement had not been exercised and were outstanding. These warrants expire in November 2017.

Notes to Financial Statements

 

In May 2014, the Company entered into an amendment, or the Lease Amendment, to that certain lease dated December 21, 2011, with Metropolitan Life Insurance Company, or the Existing Lease, for 13,787 square feet of space located at 301 Galveston Drive, Redwood City, California, or the Current Premises. Pursuant to the Lease Amendment, the term of the Existing Lease has been extended for a period of twenty (20) months and twenty-two (22) days and expiring January 31, 2018, or the Expiration Date, unless sooner terminated pursuant to the terms of the Existing Lease. In addition, the Lease Amendment included a new lease on an additional 12,106 square feet of office space, or the Expansion Space, which is adjacent to the current premises. The new lease for the Expansion Space has a term of 42 months commencing on August 1, 2014, and expiring on the Expiration Date. The Company has an option to extend the term of the Lease Amendment for an additional five years, which would commence upon the Expiration Date, at a market rate determined according to the Existing Lease.

 

Rent expense was $0.5 million, $0.3 million and $0.3 million during the years ended December 31, 2014, 2013 and 2012, respectively.

Litigation

 

On October 1, 2014, a securities class action complaint was filed in the U.S. District Court for the Northern District of California against AcelRx and certain of the Company’s current and former officers. The complaint alleges that between December 2, 2013 and September 25, 2014, AcelRx and certain of the Company’s officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with statements related to the Company’s lead drug candidate, Zalviso. The complaint seeks unspecified damages, interest, attorneys’ fees, and other costs. On December 1, 2014, three purported shareholders filed motions to appoint lead plaintiff and to appoint lead counsel. On February 24, 2015, the court issued an order appointing the lead plaintiff and lead counsel in the matter. Lead Plaintiff has until April 10, 2015 to file an amended complaint. The last day for the Company to respond to the amended complaint is May 26, 2015. The Company believes that it has meritorious defenses and intends to defend against this lawsuit vigorously.

 

From time to time the Company may be involved in additional legal proceedings arising in the ordinary course of business. The Company does not have contingent liabilities established for any litigation matters.

 

Manufacturing Agreements

 

Patheon

 

In January 2013, the Company and Patheon entered into a Manufacturing Services Agreement, or the Services Agreement, and a related Amended and Restated Capital Expenditure and Equipment Agreement, or the Amended Capital Agreement, relating to the manufacture of sufentanil sublingual tablets, or the Product, for use with the Company’s Zalviso System.

 

Under the terms of the Services Agreement, the Company has agreed to purchase, subject to Patheon’s continued material compliance with the terms of the Services Agreement, all of its Product requirements for the United States, Canada and Mexico from Patheon during the Initial Term of the Services Agreement (as defined below), and at least eighty percent (80%) of its Product requirements for such territories after the Initial Term.

Notes to Financial Statements

 

The term of the Services Agreement extends until December 31, 2017, or the Initial Term, and will automatically renew thereafter for periods of two years, unless terminated by either party upon eighteen months’ prior written notice; provided, however, that the Services Agreement may not be terminated without cause prior to the end of the Initial Term.

 

Under the terms of the Amended Capital Agreement, the Company has made and has the option to make certain future modifications to Patheon’s Cincinnati facility and which would be the responsibility of the Company. If additional equipment and facility modifications are required to meet the Company’s Product needs, the Company may be required to contribute to the cost of such additional equipment and facility modifications. The Amended Capital Agreement also requires that the Company make payments in 2012 and 2013 totaling $480,000, which the Company made, to Patheon to partially offset taxes incurred and paid by Patheon in connection with facility modifications already completed by Patheon. There were no such payments due in 2014. The Company can seek reimbursement from Patheon for these payments if it receives approval from the FDA for Zalviso. The Amended Capital Agreement further requires that the Company pay a maximum “overhead fee” of $200,000 annually during the term of the Services Agreement, which amount may be reduced to $0 based on the amount of annual revenues earned by Patheon under the Services Agreement and the pre-existing development agreements. No fee was due in 2013 or 2014 based on the amount of revenues earned by Patheon from the Company.

 

Expenditures associated with the aforementioned agreements are primarily driven by the potential commercial requirements and demand for the Company’s products, none of which have been approved for commercialization; accordingly, the amounts and timing of such future expenditures cannot be determined at this time.

 

Grünenthal

 

On December 16, 2013, the Company and Grünenthal GmbH, or Grünenthal, entered into a Collaboration and License Agreement, or the License Agreement, and related Manufacture and Supply Agreement, or the Manufacturing Agreement, and together with the License Agreement, the Agreements. The License Agreement grants Grünenthal rights to commercialize Zalviso, the Company’s novel sublingual patient-controlled analgesia, or PCA, system, or the Product, in the countries of the European Union, Switzerland, Liechtenstein, Iceland, Norway and Australia, or the Territory, for human use in pain treatment within or dispensed by hospitals hospices, nursing homes and other medically-supervised settings, or the Field.

 

Under the terms of the Manufacturing Agreement, the Company will manufacture and supply the Product for use in the Field for the Territory exclusively for Grünenthal. Grünenthal shall purchase from AcelRx, during the first five years after the effective date of the Manufacturing Agreement, 100% and thereafter 80% of Grünenthal’s and its sublicensees’ and distributors’ requirements of Product for use in the Field for the Territory. The Product will be supplied at the Company’s fully burdened manufacturing cost (as defined in the Manufacturing Agreement). The Manufacturing Agreement requires the Company to use commercially reasonable efforts to enter stand-by contracts with third parties providing significant supply and manufacturing services and under certain specified conditions permits Grünenthal to use a third party back-up manufacturer to manufacture the Product for Grünenthal’s commercial sale in the Territory.

 

Unless earlier terminated, the Manufacturing Agreement continues in effect until the later of the expiration of the obligation of Grünenthal to make royalty and supply and trademark fee payments or the end of any transition period for manufacturing obligations due to the expiration or termination of the License Agreement. The Manufacturing Agreement is subject to earlier termination in connection with certain termination events in the License Agreement, in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party or upon the bankruptcy or insolvency of either party.

 

Under the Supply Agreement, the Company will exclusively manufacture and supply the Product to Grünenthal for the Field in the Territory.

 

Expenditures associated with the aforementioned agreements are primarily driven by the potential commercial requirements and demand for the Company’s products, none of which are currently approved for commercial use; accordingly, the amounts and timing of such future expenditures cannot be determined at this time.

Notes to Financial Statements

 

On July 23, 2013, AcelRx completed an underwritten public offering of 4,370,000 shares of common stock, at a price of $11.65 per share to the public. The total gross proceeds of this offering were $50.9 million with net proceeds to AcelRx of $47.9 million after deducting underwriting discounts and commissions and other expenses payable by AcelRx.

 

In December 2012, AcelRx completed an underwritten public offering, in which the Company sold an aggregate of 14,375,000 shares of its common stock at a public offering price of $3.31 per share, resulting in net proceeds of $44.1 million, after deducting underwriting discounts and commissions and other offering related expenses totaling $3.5 million.

 

Private Placement Offering

 

On June 1, 2012, or the Issuance Date, the Company issued an aggregate of 2,922,337 shares of common stock and warrants to purchase up to 2,630,103 shares of common stock, or the PIPE warrants, for aggregate gross proceeds of $10.0 million, or the Private Placement. Costs related to the offering were $0.9 million. The shares of common stock and PIPE warrants issued in the Private Placement were sold pursuant to a Securities Purchase Agreement, or Purchase Agreement, dated May 29, 2012, between the Company and certain purchasers, including certain entities affiliated with Mark Wan and Stephen J. Hoffman, members of the Company’s board of directors. Pursuant to the Purchase Agreement, AcelRx sold shares of common stock and PIPE warrants to purchase common stock in immediately separable “Units,” with each Unit consisting of (i) one share of common stock and (ii) a PIPE warrant to purchase 0.9 of a share of common stock. The per share exercise price of the PIPE warrants was $3.40. The offering price per Unit was $3.40 for non-affiliated investors, and $3.5125 for affiliated investors, which equals the sum of (i) $3.40, the closing consolidated bid price of the Company’s common stock on May 29, 2012, plus (ii) $0.1125 (which is equal to $0.125 per PIPE warrant share, multiplied by 0.9), for an aggregate amount of $10.0 million. The PIPE warrants issued in the Private Placement became exercisable six months after the Issuance Date, and expire on the five year anniversary of the initial exercisability date.

 

In connection with the Private Placement, the Company filed a registration statement with the U.S. Securities and Exchange Commission, or SEC, registering for resale the shares of common stock and shares of common stock issuable upon exercise of the warrants sold in the Private Placement. The registration statement was declared effective by the SEC in July 2012.

 

Stock Plans

 

2011 Equity Incentive Plan

 

In January 2011, the board of directors adopted, and the Company’s stockholders approved, the 2011 Equity Incentive Plan, or 2011 Incentive Plan, as a successor to the 2006 Plan. The 2011 Incentive Plan became effective immediately upon the execution and delivery of the underwriting agreement for the IPO on February 10, 2011. As of February 10, 2011, no more awards may be granted under the 2006 Plan, although all outstanding stock options and other stock awards previously granted under the 2006 Plan will continue to remain subject to the terms of the 2006 Plan. The 51,693 shares reserved under the 2006 Plan that remained available for future grant at the time of the IPO were transferred to the share reserve of the 2011 Incentive Plan.

 

The initial aggregate number of shares of the Company’s common stock that may be issued pursuant to stock awards under the 2011 Incentive Plan is 1,875,000 shares, which number was the sum of (i) 51,693 shares remaining available for future grant under the 2006 Plan at the time of the execution and delivery of the underwriting agreement for the Company’s IPO, and (ii) an additional 1,823,307 new shares. Then, the number of shares of common stock reserved for issuance under the 2011 Incentive Plan will automatically increase on January 1st each year, starting on January 1, 2012 and continuing through January 1, 2020, by 4% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or such lesser number of shares of common stock as determined by the board of directors.

 

On March 17, 2014, the Company filed a Form S-8 (File Number 333-194634) with the SEC registering 1,722,023 shares of common stock, par value $0.001 per share, under the 2011 Equity Incentive Plan.

 

On March 12, 2013, the Company filed a Form S-8 (File Number 333-187206) with the SEC registering 1,482,201 shares of common stock, par value $0.001 per share, under the 2011 Equity Incentive Plan.

 

On March 26, 2012, the Company filed a Form S-8 (File Number 333-180334) with the SEC registering 782,711 shares of common stock, par value $0.001 per share, under the 2011 Equity Incentive Plan.

2011 Employee Stock Purchase Plan

 

Additionally, in January 2011, the board of directors adopted, and the Company’s stockholders approved, the 2011 Employee Stock Purchase Plan, or the ESPP, which also became effective immediately upon the execution and delivery of the underwriting agreement for the IPO.

 

Initially, 250,000 shares of the Company’s common stock were authorized for issuance under the ESPP pursuant to purchase rights granted to the Company’s employees or to employees of any of its designated affiliates. The number of shares of the Company’s common stock reserved for issuance will automatically increase on January 1st each year, starting January 1, 2012 and continuing through January 1, 2020, in an amount equal to the lower of (1) 2% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or (2) a number of shares of common stock as determined by the board of directors. If a purchase right granted under the ESPP terminates without having been exercised, the shares of the Company’s common stock not purchased under such purchase right will be available for issuance under the ESPP.

 

On March 26, 2012, the Company filed a Form S-8 (File Number 333-180334) with the SEC registering 391,355 shares of common stock, par value $0.001 per share, under the 2011 Employee Stock Purchase Plan.

 

As of December 31, 2014, 254,337 shares have been issued to employees and there are 387,018 shares available for issuance under the ESPP. The weighted average fair value of shares issued under the ESPP in 2014, 2013 and 2012 was $4.35, $3.97 and $2.45 per share, respectively.

 

2006 Stock Plan

 

In August 2006, the Company established the 2006 Plan in which 342,000 shares of common stock were originally reserved for the issuance of incentive stock options, or ISOs, and nonstatutory stock options, or NSOs, to employees, directors or consultants of the Company. In February 2008, an additional 375,000 shares of common stock were reserved for issuance under the 2006 Plan and, in November 2009, an additional 1,376,059 shares of common stock were reserved for issuance under the 2006 Plan. Per the 2006 Plan, the exercise price of ISOs and NSOs granted to a stockholder who at the time of grant owns stock representing more than 10% of the voting power of all classes of the stock of the Company could not be less than 110% of the fair value per share of the underlying common stock on the date of grant. Effective upon the execution and delivery of the underwriting agreement for the Company’s IPO, no additional stock options or other stock awards may be granted under the 2006 Plan.

Restricted Stock Units

 

In March 2011, the Company granted 343,815 Restricted Stock Units, or RSUs, to employees and directors under the 2011 Plan at a grant date fair value of $3.45. The fair value of the RSUs was determined on the date of grant based on the market price of the Company’s common stock. RSUs are recognized as expense ratably over the vesting period and the Company’s RSU’s generally vest over three years as follows: 25% on the 6 month anniversary of the vesting commencement date, 25% on the 12 month anniversary of the vesting commencement date, 25% on the 24 month anniversary of the vesting commencement date and 25% on the 36 month anniversary of the vesting commencement date, so long as the RSU recipient continues to provide services to the Company. As of December 31, 2014, there were no RSUs outstanding. The expense related to RSUs during the years ended December 31, 2014, 2013 and 2012 was $56,000, $290,000 and $315,000, respectively.

11. Net Loss per Share of Common Stock

 

The Company’s basic net loss per share of common stock is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. The diluted net loss per share of common stock is computed by giving effect to all potential common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of this calculation, options to purchase common stock and warrants to purchase common stock were considered to be common stock equivalents. In periods with a reported net loss, common stock equivalents are excluded from the calculation of diluted net loss per share of common stock if their effect is antidilutive.

 

During the year ended December 31, 2014, the PIPE warrants had a dilutive impact to net loss per share due to a lower share price at December 31, 2014, compared to the closing share price on December 31, 2013. The decrease in share price created a lower Black-Scholes value and lower liability for the PIPE warrants, which resulted in other income during the year ended December 31, 2014. The calculation of diluted net loss per share requires that, to the extent the average market price of the underlying shares for the reporting period exceeds the exercise price of the PIPE warrants and the presumed exercise of such securities are dilutive to loss per share for the period, adjustments to net loss used in the calculation are required to remove the change in fair value of the PIPE warrants for the period. Likewise, adjustments to the denominator are required to reflect the related dilutive shares.

 

The following table is a reconciliation of the numerators and denominators used in the calculation of basic and diluted net loss per share computations for the years ended December 31, 2014, 2013 and 2012:

13. 401(k) Plan

 

The Company sponsors a 401(k) plan that stipulates that eligible employees can elect to contribute to the 401(k) plan, subject to certain limitations. Pursuant to the 401(k) plan, the Company makes a discretionary safe harbor contribution equal to 3% of the related compensation. Eligible employees are 100% vested in this safe harbor contribution regardless of whether they make salary deferrals into the 401(k) plan. Company contributions were $201,000, $143,000 and $120,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Notes to Financial Statements

 

 

Reconciliations of the statutory federal income tax to the Company’s effective tax during the years ended December 31, 2014, 2013 and 2012 are as follows (in thousands):

 

   

Year Ended December 31,

 
    2014    

2013

   

2012

 

Tax at statutory federal rate

  $ (11,392 )   $ (7,965 )   $ (11,343 )

    (2,501 )     (716 )     (1,953 )

    20       (80 )     807  

Change in valuation allowance

    16,351       5,189       11,949  

Provision (benefit) for income taxes

  $     $     $  

 

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of deferred tax assets is dependent on future taxable income, if any, the timing and the amount of which are uncertain. Accordingly, the deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $16.4 million, $4.8 million and $11.9 million during the years ended December 31, 2014, 2013 and 2012, respectively. The amount of the valuation allowance for deferred tax assets associated with excess tax deduction from stock based compensation arrangement that is allocated to contributed capital if the future tax benefits are subsequently recognized is $2.8 million.

 

As of December 31, 2014, the Company had federal net operating loss carryforwards of $109.1 million, which begin to expire in 2025. As of December 31, 2014, the Company had state net operating loss carryforwards of $109.1 million, which begin to expire in 2015.

 

As of December 31, 2014, the Company had federal research credit carryovers of $3.3 million, which begin to expire in 2026. As of December 31, 2014, the Company had state research credit carryovers of $1.7 million, which will carryforward indefinitely.

 

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change”, generally defined as a greater than 50% change (by value) in its equity ownership over a three year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research credits, to offset its post-change income may be limited. Based on an analysis performed by the Company as of December 31, 2014, it was determined that two ownership changes have occurred since inception of the Company. The first ownership change occurred in 2006 at the time of the Series A financing and, as a result of the change, $1.4 million in federal and state net operating loss carryforwards will expire unutilized. In addition, $26,000 in federal and state research and development credits will expire unutilized. The second ownership change occurred in July 2013 at the time of the underwritten public offering; however, the Company believes the resulting annual imposed limitation on use of pre-change tax attributes is sufficiently high that the limit itself will not result in unutilized pre-change tax attributes.

 

 

Uncertain Tax Positions

 

A reconciliation of the beginning and ending balances of the unrecognized tax benefits during the years ended December 31, 2014, 2013 and 2012 is as follows (in thousands):

 

   

Year Ended December 31,

 
    2014    

2013

   

2012

 

Unrecognized benefit—beginning of period

  $ 1,341     $ 810     $ 748  

Gross decreases—prior period tax positions

          221       (17 )

Gross increases—current period tax positions

    326       310       79  

Unrecognized benefit—end of period

  $ 1,667     $ 1,341     $ 810  

 

The entire amount of the unrecognized tax benefits would not impact the Company’s effective tax rate if recognized.

 

Accrued interest and penalties related to unrecognized tax benefits are classified as income tax expense and were immaterial. The Company files income tax returns in the United States and in California. The tax years 2007 through 2013 remain open in both jurisdictions. The Company is not currently under examination by income tax authorities in federal, state or other foreign jurisdictions.

15. Subsequent Events

 

In March 2015, the Company announced that it had received correspondence from the FDA stating that in addition to the bench testing and two Human Factors studies the Company had performed for Zalviso in order to address the issues raised in the CRL, an additional clinical study is needed to assess the risk of inadvertent dispensing and overall risk of dispensing failures. The Company intends to meet with the FDA to discuss and clarify the need for an additional clinical study, and the potential design and objectives of such a study. This event has no impact on the Financial Statements as presented herein.

On behalf of AcelRx Pharmaceuticals, Inc. (the “Company”), I am pleased to offer you the full time position of Chief Legal Officer. Speaking for myself, as well as the other members of the Company’s management team, we are all very impressed with your credentials and we look forward to your future success in this position.

 

The terms of your new position with the Company are as set forth below:

 

1.     Position.

 

(a)     Your job title will be Chief Legal Officer, and your primary work location will be AcelRx Headquarters in Redwood City, California. You will report to Richard King, Chief Executive Officer. Of course, the Company may change your position, duties, and work location from time to time at its discretion.

 

(b)      You agree to the best of your ability and experience that you will at all times loyally and conscientiously perform all of the duties and obligations required of and from you pursuant to the express and implicit terms hereof, and to the reasonable satisfaction of the Company. During the term of your employment, you further agree that you will devote 100% of your business time and attention to the business of the Company, the Company will be entitled to all of the benefits and profits arising from or incident to all such work services and advice, you will not render commercial or professional services of any nature to any person or organization, whether or not for compensation, without the prior written consent of the Company, such consent not to be unreasonably withheld, and you will not directly or indirectly engage or participate in any business that is competitive in any manner with the business of the Company. Nothing in this letter agreement will prevent you from accepting speaking or presentation engagements in exchange for honoraria or from serving on boards of charitable organizations, from owning no more than one percent (1%) of the outstanding equity securities of a corporation whose stock is listed on a national stock exchange or serving on no more than one board of directors of another noncompetitive domestic or international company; provided, however, that in all cases, these activities do not unreasonably detract from the performance of your duties for the Company.

 

2.     Start Date. Subject to fulfillment of any conditions imposed by this letter agreement, you will commence this new position with the Company on July 14, 2014 (the “Start Date”).

 

3.     Compensation. You will be paid a monthly salary of $24,000, less required deductions and withholdings, which is equivalent to $288,000 on an annualized basis (the “Base Salary”). Your salary will be payable in two equal payments per month pursuant to the Company’s regular payroll policy. The Base Salary will be reviewed annually as part of the Company’s normal salary review process. In addition to your base salary, you will have the opportunity to earn a target annual bonus of up to 35% of your earned salary based on achievement of a series of personal and company objectives that the Company will set for you. The Company shall have the sole discretion to determine whether you have earned any such bonus and, if so, the amount of any such bonus. The bonus will be considered earned only when it is approved by the Company’s Board of Directors.

4.      Bonus Advance.  In addition, you will receive a one-time bonus advance in the amount of $50,000 (less payroll deductions and withholdings) (the “Bonus Advance”) which would be considered earned if you remain employed by the Company for one year after your start date.  This amount would be subject to required deductions and withholdings and will be paid to you in the first regular payroll following 30 days of active employment.  If you resign your employment for any reason or if you are terminated for cause prior to one (1) year of your start date, you will be required to repay the gross amount of the Bonus Advance to the Company and you authorize the Company to withhold any amount due from any final payments due to you, subject to applicable law.

 

5.     Stock Option Grant. In connection with the commencement of your employment, the Company will recommend that the Board of Directors, at the next regularly scheduled meeting, grant you an option to purchase 65,000 shares of the Company’s Common Stock (“Option Shares”) with an exercise price equal to the fair market value on the date of the grant. These option shares will vest at the rate of 25% of the shares on the twelve (12) month anniversary of your Vesting Commencement Date (as defined in your Stock Option Agreement, which date will be your Start Date, as defined above) and the remaining Option Shares will vest monthly thereafter at the rate of 1/48 of the total number of the Option Shares per month. Vesting will, of course, depend on your continued employment with the Company. The option will be subject to the terms of the Company’s 2011 Equity Incentive Plan and the Stock Option Agreement between you and the Company.

 

6.     Benefits.

 

(a)     Insurance Benefits. The Company will provide you with the opportunity to participate in the standard benefits plans currently available to other Company employees, subject to any eligibility requirements imposed by such plans.

 

(b)     Vacation; Sick Leave. You will be entitled to paid time off according to the Company’s standard policies.

 

(c)     Employee Stock Purchase Plan (ESPP). You will be eligible to participate in the Company’s ESPP.

 

(d)     401 (k) Plan. You will be eligible to participate in the Company’s 401 (k) Plan.

7.      Change of Control Severance Benefits.

 

(a)     Severance Benefits. If: (i) the Company undergoes a Change in Control (as such term is defined in the Plan); and (ii) during the period which begins three (3) months prior to consummation of the Change in Control and ends twelve (12) months following the closing of the Change in Control, the Company terminates your employment without Cause (as such term is defined in the Plan) or you terminate your employment due to an Involuntary Resignation (as such defined below); and (iii) you execute and allow to become effective a general release of all claims against the company in a format acceptable to the Company, then the Company will provide you with the following severance benefits:

 

(i)      The vesting of the Option Shares and any additional grant of options to purchase shares of the company’s common stock subsequently awarded to you by the Board (collectively, the “Employee Options”) shall accelerate in full such that 100% of the then unvested Employee Options will become immediately vested and exercisable as of your termination date;

 

(b)     Involuntary Resignation.     For purposes of this Paragraph 7, an “Involuntary Resignation” shall mean your resignation of employment with the Company within thirty (30) days following the occurrence of any of the following events without your written consent and after providing the Company with thirty (30) days to cure such event: (i) a material reduction or change in your job duties, reporting relationships, responsibilities and requirements inconsistent with your position with the Company and prior duties, reporting relationships, responsibilities and requirements prior to the Change in Control, provided that neither a mere change in title alone nor reassignment following a Change in Control to a position that is substantially similar to the position held prior to the Change in Control in terms of job duties, responsibilities or requirements shall constitute a material reduction in job responsibilities; (ii) a reduction in your then-current base salary by at least 20%, provided that an across-the-board reduction in the salary level of all other senior executives by the same percentage amount as part of a general salary level reduction shall not constitute such a salary reduction, or (iii) the relocation of your principal place for performance of your Company duties to a location more than thirty (30) miles from the Company’s then current location.

 

8.     Confidential Information and Invention Assignment Agreement. Your acceptance of this offer and commencement of employment with the Company is contingent upon the execution of, and delivery to an officer of the Company, the Company’s Confidential Information and Invention Assignment Agreement, a copy of which is enclosed for your review and execution (the “Confidentiality Agreement”), prior to or on your Start Date.

 

9.     At-Will Employment. Your employment with the Company will be on an “at will” basis, meaning that either you or the Company may terminate your employment at any time, with or without cause, and with or without advance notice.

 

10.     No Conflicting Obligations. You understand and agree that, by accepting this offer of employment, you represent to the Company that your performance will not breach any other agreement to which you are a party and that you have not, and will not during the term of your employment with the Company, enter into any oral or written agreement in conflict with any of the provisions of this letter or the Company’s policies. You are not to bring with you to the Company, or use or disclose to any person associated with the Company, any confidential or proprietary information belonging to any former employer or other person or entity with respect to which you owe an obligation of confidentiality under any agreement or otherwise. The Company does not need and will not use such information and we will assist you in any way possible to preserve and protect the confidentiality of proprietary information belonging to third parties. Also, we expect you to abide by any obligations to refrain from soliciting any person employed by or otherwise associated with any former employer and suggest that you refrain from having any contact with such persons until such time as any non-solicitation obligation expires.

CONFIDENTIAL INFORMATION AND
INVENTION ASSIGNMENT AGREEMENT

 

 

As a condition of my becoming employed (or my employment being continued) by or retained as a consultant (or my consulting relationship being continued) by AcelRx Pharmaceuticals, Inc., a Delaware corporation (“AcelRx”) or any of its current or future subsidiaries, affiliates, successors or assigns (collectively, the “Company”), and in consideration of my employment or consulting relationship with the Company and my receipt of the compensation now and hereafter paid to me by the Company, I agree to the following:

 

1.     Employment or Consulting Relationship. I understand and acknowledge that this Agreement does not alter, amend or expand upon any rights I may have to continue in the employ of, or in a consulting relationship with, or the duration of my employment or consulting relationship with, the Company under any existing agreements between the Company and me or under applicable law. Any employment or consulting relationship between the Company and me, whether commenced prior to or upon the date of this Agreement, shall be referred to herein as the “Relationship.”

 

2.     Duties. I will perform for the Company such duties as may be designated by the Company from time to time. During the Relationship, I will devote my best efforts to the interests of the Company and will not engage in other employment or in any activities detrimental to the best interests of the Company without the prior written consent of the Company.

 

3.     At-Will Relationship. I understand and acknowledge that my Relationship with the Company is and shall continue to be at-will, as defined under applicable law, meaning that either I or the Company may terminate the Relationship at any time for any reason or no reason, without further obligation or liability.

 

4.     Confidential Information.

 

(a)     Company Information. I agree at all times during the term of my Relationship with the Company and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company to the extent necessary to perform my obligations to the Company under the Relationship, or to disclose to any person, firm, corporation or other entity without written authorization of the Board of Directors of the Company, any Confidential Information of the Company which I obtain or create. I further agree not to make copies of such Confidential Information except as authorized by the Company. I understand that “Confidential Information” means any Company proprietary information, technical data, trade secrets or know-how, including, but not limited to, research, product plans, products, services, suppliers, customer lists and customers (including, but not limited to, customers of the Company on whom I called or with whom I became acquainted during the Relationship), prices and costs, markets, software, developments, inventions, laboratory notebooks, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, licenses, finances, budgets or other business information disclosed to me by the Company either directly or indirectly in writing, orally or by drawings or observation of parts or equipment or created by me during the period of the Relationship, whether or not during working hours. I understand that Confidential Information includes, but is not limited to, information pertaining to any aspect of the Company’s business which is either information not known by actual or potential competitors of the Company or other third parties not under confidentiality obligations to the Company, or is otherwise proprietary information of the Company or its customers or suppliers, whether of a technical nature or otherwise. I further understand that Confidential Information does not include any of the foregoing items which has become publicly and widely known and made generally available through no wrongful act of mine or of others who were under confidentiality obligations as to the item or items involved.

 

 

 
 

 

 

(b)     Prior Obligations. I represent that my performance of all terms of this Agreement as an employee or consultant of the Company has not breached and will not breach any agreement to keep in confidence proprietary information, knowledge or data acquired by me prior or subsequent to the commencement of my Relationship with the Company, and I will not disclose to the Company or use any inventions, confidential or non-public proprietary information or material belonging to any current or former client or employer or any other party. I will not induce the Company to use any inventions, confidential or non-public proprietary information, or material belonging to any current or former client or employer or any other party. I acknowledge and agree that I have listed on Exhibit D all agreements (e.g., non-competition agreements, non-solicitation of customers agreements, non-solicitation of employees agreements, confidentiality agreements, inventions agreements, etc.) with a current or former employer, or any other person or entity, that may restrict my ability to accept employment with the Company or my ability as an employee or consultant to recruit or engage customers or service providers on behalf of the Company, or otherwise relate to or restrict my ability to perform my duties as an employee of the Company or any obligation I may have to the Company.

 

(c)     Third Party Information. I recognize that the Company has received and in the future will receive confidential or proprietary information from third parties subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. I agree to hold all such confidential or proprietary information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out my work for the Company consistent with the Company’s agreement with such third party.

 

5.     Inventions.

 

(a)     Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a list describing with particularity all inventions, original works of authorship, developments, improvements, and trade secrets which were made by me prior to the commencement of the Relationship (collectively referred to as “Prior Inventions”), which belong solely to me or belong to me jointly with another, which relate in any way to any of the Company’s proposed businesses, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached, I represent that there are no such Prior Inventions. If, in the course of my Relationship with the Company, I incorporate into a Company product, process or machine a Prior Invention owned by me or in which I have an interest, the Company is hereby granted and shall have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell and otherwise distribute such Prior Invention as part of or in connection with such product, process or machine.

 

 

 
 -2-

 

 

(b)     Assignment of Inventions. I agree that I will promptly make full written disclosure to AcelRx, will hold in trust for the sole right and benefit of AcelRx, and hereby assign to AcelRx, or its designee, all my right, title and interest throughout the world in and to any and all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the period of my Relationship with the Company (collectively referred to as “Inventions”), except as provided in Section 5(e) below. I further acknowledge that all Inventions which are made by me (solely or jointly with others) within the scope of and during the period of my Relationship with the Company are “works made for hire” (to the greatest extent permitted by applicable law) and are compensated by my salary (if I am an employee) or by such amounts paid to me under any applicable consulting agreement or consulting arrangements (if I am a consultant), unless regulated otherwise by the mandatory law of the state of California.

 

(c)     Maintenance of Records. I agree to keep and maintain adequate and current written records of all Inventions made by me (solely or jointly with others) during the term of my Relationship with the Company. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, laboratory notebooks, and any other format. The records will be available to and remain the sole property of the Company at all times. I agree not to remove such records from the Company’s place of business except as expressly permitted by Company policy which may, from time to time, be revised at the sole election of the Company for the purpose of furthering the Company’s business. I agree to return all such records (including any copies thereof) to AcelRx at the time of termination of my Relationship with the Company as provided for in Section 6.

 

(d)     Patent and Copyright Rights. I agree to assist AcelRx, or its designee, at its expense, in every proper way to secure AcelRx’s, or its designee’s, rights in the Inventions and any copyrights, patents, trademarks, mask work rights, moral rights, or other intellectual property rights relating thereto in any and all countries, including the disclosure to AcelRx or its designee of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments which AcelRx or its designee shall deem necessary in order to apply for, obtain, maintain and transfer such rights, or if not transferable, waive such rights, and in order to assign and convey to AcelRx or its designee, and any successors, assigns and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of this Agreement until the expiration of the last such intellectual property right to expire in any country of the world. If AcelRx or its designee is unable because of my mental or physical incapacity or unavailability or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents, copyright, mask works or other registrations covering Inventions or original works of authorship assigned to AcelRx or its designee as above, then I hereby irrevocably designate and appoint AcelRx and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance or transfer of letters patent, copyright or other registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to AcelRx or its designee any and all claims, of any nature whatsoever, which I now or hereafter have for infringement of any and all proprietary rights assigned to AcelRx or such designee.

 

 

 
 -3-

 

 

(e)     Exception to Assignments. I understand that the provisions of this Agreement requiring assignment of Inventions to AcelRx do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870 (attached hereto as Exhibit B). I will advise the Company promptly in writing of any inventions that I believe meet such provisions and are not otherwise disclosed on Exhibit A.

 

6.     Company Property; Returning Company Documents. I acknowledge and agree that I have no expectation of privacy with respect to the Company’s telecommunications, networking or information processing systems (including, without limitation, stored company files, e-mail messages and voice messages) and that my activity and any files or messages on or using any of those systems may be monitored at any time without notice. I further agree that any property situated on the Company’s premises and owned by the Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice. I agree that, at the time of termination of my Relationship with the Company, I will deliver to the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, laboratory notebooks, materials, flow charts, equipment, other documents or property, or reproductions of any of the aforementioned items developed by me pursuant to the Relationship or otherwise belonging to the Company, its successors or assigns. In the event of the termination of the Relationship, I agree to sign and deliver the “Termination Certification” attached hereto as Exhibit C; however, my failure to sign and deliver the Termination Certificate shall in no way diminish my continuing obligations under this Agreement.

 

7.     Notification to Other Parties.

 

(a)     Employees. In the event that I leave the employ of the Company, I hereby consent to notification by the Company to my new employer about my rights and obligations under this Agreement.

 

(b)     Consultants. I hereby grant consent to notification by the Company to any other parties besides the Company with whom I maintain a consulting relationship, including parties with whom such relationship commences after the effective date of this Agreement, about my rights and obligations under this Agreement.

 

 

 
-4- 

 

 

8.     Solicitation of Employees, Consultants and Other Parties. I agree that during the term of my Relationship with the Company, and for a period of twelve (12) months immediately following the termination of my Relationship with the Company for any reason, whether with or without cause, I shall not either directly or indirectly solicit, induce, recruit or encourage any of the Company’s employees or consultants to terminate their relationship with the Company, or attempt to solicit, induce, recruit, encourage or take away employees or consultants of the Company, either for myself or for any other person or entity. Further, during my Relationship with the Company and at any time following termination of my Relationship with the Company for any reason, with or without cause, I shall not use any Confidential Information of the Company to attempt to negatively influence any of the Company’s clients or customers from purchasing Company products or services or to solicit or influence or attempt to influence any client, customer or other person either directly or indirectly, to direct his or its purchase of products and/or services to any person, firm, corporation, institution or other entity in competition with the business of the Company.

 

9.     Representations and Covenants.

 

(a)     Facilitation of Agreement. I agree to execute promptly any proper oath or verify any proper document required to carry out the terms of this Agreement upon the Company’s written request to do so.

 

(b)     Conflicts. I represent that my performance of all the terms of this Agreement does not and will not breach any agreement I have entered into, or will enter into with any third party, including without limitation any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to commencement of my Relationship with the Company. I agree not to enter into any written or oral agreement that conflicts with the provisions of this Agreement.

 

 (c)     Voluntary Execution. I certify and acknowledge that I have carefully read all of the provisions of this Agreement and that I understand and will fully and faithfully comply with such provisions.

(2) Result from any work performed by the employee for the employer.
