Item 1.Business

 

Overview

 

Pain Therapeutics, Inc. develops proprietary drugs that offer significant improvements to patients and healthcare professionals. We generally focus our drug development efforts on disorders of the nervous system, such as chronic pain.

 

Our expertise consists of developing new drug candidates and guiding these through various regulatory and development pathways in preparation for their eventual commercialization. By necessity, the conduct of drug development is complex, lengthy, expensive and risky. The FDA has not yet established the safety or efficacy of our drug candidates.

 

For over a decade, we have pioneered technology, tools and techniques that enable the development of Abuse-Deterrent Formulations, or ADFs. ADFs are intended to make opioid drugs difficult to abuse yet provide steady pain relief when used appropriately by patients. ADFs are intended to help in the fight against prescription drug abuse.

 

Opioid drugs, such as oxycodone, are an important treatment option for patients with severe chronic pain. However, misuse, abuse and diversion of these prescription drugs remains a serious, persistent problem. Nearly 19,000 people died from opioid overdose in 2014, according to the NIH’s National Institute on Drug Abuse.

 

Our lead drug candidate is called REMOXY (oxycodone capsules CII). REMOXY is a proprietary, abuse-deterrent, oral formulation of oxycodone (CII). We developed REMOXY to make oxycodone difficult to abuse yet provide 12 hours of steady pain relief when used appropriately by patients.

In particular, REMOXY’s thick, sticky, high viscosity formulation may deter unapproved routes of drug administration, such as injection, snorting or smoking. REMOXY targets the $2.5 billion marketplace for long-acting formulations of oxycodone. We own exclusive, worldwide rights to REMOXY.

 

In March 2016, we plan to submit to the FDA a New Drug Application, or NDA, for REMOXY. The REMOXY NDA has priority review status with the FDA. We expect a review cycle of about six months. This is a 505(b)(2) NDA resubmission for five dosage strengths of REMOXY (5, 10, 20, 30, 40 mg). The drug’s proposed indication is “for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate”. The safety and clinical efficacy of REMOXY is supported by multiple studies, including a successful Phase III efficacy program conducted under an FDA Special Protocol Assessment. REMOXY’s abuse-deterrence is supported by a body of clinical and non-clinical data, including data comparing REMOXY against currently marketed oxycodone products. The NDA will propose label claims that properly characterize REMOXY’s abuse-deterrent properties, including certain routes

of abuse that REMOXY may deter, such as injection, snorting or smoking. The NDA also includes stability data that we believe meet FDA guidance criteria in support of a 24-month shelf life.

 

Use and Abuse of Opioid Drugs

 

Opioid drugs are primarily used to relieve pain. They are among the world’s oldest known drugs. The term ‘opioid’ refers to an entire class of analgesic substances that are derived from the opium poppy plant. Drugs that fall within this class include oxycodone, hydrocodone, fentanyl, heroin, morphine and many other related substances.

 

In recent decades, oxycodone, a semi-synthetic opium derivative, has become a standard of care to treat severe chronic pain. Oxycodone is in Schedule II of the federal Controlled Substances Act of 1970, which means it has accepted medical use with severe restrictions, a high potential for abuse and regulations around its manufacture, possession, storage, use and distribution.

 

Oxycodone can provide significant therapeutic benefits for patients in pain when used as prescribed. In recent years, patients with severe chronic pain have benefited from oxycodone in long-acting formulations. Long-acting formulations contain a very high dose of oxycodone that is intended to release evenly over 12 hours. Long-acting oxycodone offers the convenience of less-frequent dosing intervals and improved compliance, a potential win-win for prescribers and for patients with severe chronic pain.

 

However, the emergence of long-acting oxycodone has also corresponded with a dramatic increase in opioid drug abuse. Drug abuse is the use of opioid drugs for reasons other than what the drug was prescribed for, and often via unapproved routes of administration, such as injection, snorting or smoking. Opioids such as oxycodone are primarily abused due to their ability to produce a strong, if fleeting, euphoric high.

 

Drug abusers have learned effective ways to tamper with, and defeat, long-acting oxycodone formulations. Defeating the long-acting properties of an oxycodone formulation can be as easy as crushing or grinding tablets, then swallowing, injecting, snorting or smoking the crushed substance. This releases high levels of oxycodone faster than intended (called “dose-dumping”), resulting in an immediate and powerful euphoric high, as compared to swallowing an intact tablet as prescribed.

 

Opioid abuse is dangerous. Opioid abuse can lead to drug-seeking behavior, tolerance and physical or psychological dependence. Even a single episode of opioid abuse can also lead to overdose, respiratory depression or death.

 

The Role of Abuse-deterrent Formulations

 

The FDA and other important policy makers have developed a multi-pronged approach aimed at combating opioid misuse, abuse and addiction. One targeted effort has been to encourage the pharmaceutical industry to develop ADFs. In April 2015, the FDA issued a final guidance to assist the pharmaceutical industry in developing ADF opioid drug products.

 

ADFs attempt to raise the bar on opioid abuse by making it more difficult, longer or aversive to tamper with a long-acting formulation, while recognizing that no drug or drug formulation can be made abuse-proof. In particular, an ADF drug can still be misused and result in overdose simply by ingesting the drug in higher than recommended doses. ADFs are not designed to prevent opioid-induced euphoria. ADF technology aims to decrease the likelihood that a long-acting opioid formulation will dose-dump under conditions of abuse or accidental misuse. By mitigating dose-dumping, the likelihood of overdose and death associated may decrease.

 

First-generation ADFs were introduced into the marketplace in 2010. However, the relative weakness of first generation ADFs means opioid abuse continues to be a serious public health issue. Nearly 19,000 people died from opioid overdose in 2014 alone, according to the National Institute on Drug Abuse. According to the FDA, “for each death [due to narcotic pain relievers], there are an additional ten treatment admissions, 32 emergency department visits and 825 nonmedical users of these drugs.” (Source: FDA’s Efforts to Address the Misuse and Abuse of Opioids, 2/6/2013).

 

As a pioneer in the design and development of ADFs, we believe a robust design for a novel ADF relies on four basic (and mostly incompatible) objectives: i) safety and clinical efficacy when used as prescribed; ii) abuse-deterrent when abused; (iii) ease of large scale manufacturing; and (iv) novel, non-infringing intellectual property. Many ADF programs may achieve

5

 

 


 

three of these four objectives but the practical reality is that few ADFs achieve all four. We believe this is reflected in the industry’s relatively high failure rate with regards to ADFs developments for long-acting opioid formulations.

 

About REMOXY (oxycodone capsules CII)

 

Our lead drug candidate is called REMOXY. REMOXY is a proprietary, abuse-deterrent, oral formulation of oxycodone (CII). We developed REMOXY to make oxycodone difficult to abuse yet provide 12 hours of steady pain relief when used appropriately by patients.

 

REMOXY is intended to meet the needs of healthcare professionals who appropriately prescribe opioid drugs and who seek to minimize the risks of drug diversion, abuse or accidental patient misuse. In particular, REMOXY’s thick, sticky, high viscosity formulation may deter unapproved routes of drug administration, such as injection, snorting or smoking.

 

We initiated the development of REMOXY over a decade ago, before any formal guidance was in place with regards to regulatory pathways for ADFs. As a result of our pioneering efforts with REMOXY, we have developed a foundation of practical experience with regard to regulatory and development pathways for ADFs.

 

The following is a top-line chronology of the development of REMOXY:

 

"

In 2003, we filed an Investigational New Drug application, or IND, for REMOXY with the FDA.

"

In 2005, we and King Pharmaceuticals, Inc., or King, entered into an exclusive agreement to develop and commercialize REMOXY.

"

In 2008, we filed an NDA for REMOXY with the FDA. Later that year, we received a Complete Response Letter over manufacturing issues (specifically, in vitro drug stability). However, the Complete Response Letter did not question REMOXY’s safety, clinical efficacy, abuse-deterrent properties or use of the reference listed drug.

"

In 2009, King assumed sole control and responsibility for REMOXY.

"

In 2010, King resubmitted the REMOXY NDA with the FDA. In early 2011, Pfizer acquired King. References to Pfizer include references to Pfizer’s subsidiary King.

"

In 2011, Pfizer received a Complete Response Letter on the REMOXY NDA filed by King. Once again, FDA cited manufacturing issues (specifically, in vitro drug stability). Once again, the Complete Response Letter did not question REMOXY’s safety, clinical efficacy, abuse-deterrent properties or use of the reference listed drug.

"

From 2011-2014, Pfizer conducted fundamental investigations of the REMOXY formulation and its manufacture. As a result, Pfizer modified the REMOXY formulation and conducted successful studies to establish bioequivalence of the current formulation to the original formulation of REMOXY, to generate additional abuse-deterrent data and to provide manufacturing stability.

"

In 2014, Pfizer provided us with written notice of termination of its development of REMOXY. We and Pfizer agreed on an orderly transfer of all rights, data, IP, etc.

"

In 2015, we and Pfizer concluded the transfer of the REMOXY program. We believe Pfizer has transferred to us its data, materials, capital equipment and other assets related to REMOXY.

"

In 2015, we generated additional abuse-deterrent data, continued an on-going stability study and made other preparations necessary to resubmit the NDA for REMOXY with the FDA.

"

In 2016, we plan to resubmit the NDA for REMOXY with the FDA. We expect a review cycle of about six months.

 

We intend our NDA resubmission to generally follow the detailed REMOXY resubmission strategy that was previously agreed upon by Pfizer and the FDA. The safety and clinical efficacy of REMOXY is supported by multiple studies, including a successful Phase III efficacy program conducted under an FDA Special Protocol Assessment. REMOXY’s abuse-deterrence is supported by a body of clinical and non-clinical data, including data comparing REMOXY against currently marketed oxycodone products. Our abuse-deterrence studies generally examined the impact of common methods of abuse on the rate of release of oxycodone, especially in the first 0-2 hours of abuse, when abusers expect feelings of a strong euphoric high. The NDA will propose label claims that properly characterize REMOXY’s abuse-deterrent properties, including certain routes

6

 

 


 

of abuse that REMOXY may deter, such as injection, snorting or smoking. The NDA also includes stability data that we believe meet FDA guidance criteria in support of a 24-month shelf life.

 

REMOXY Commercial Opportunity

 

The global opioid market has been estimated by third-parties to be valued at nearly $35 billion in 2015. By geography, North America dominates the market, with about 65% market share, or about $22 billion. By drug, long-acting formulations of oxycodone was about a $2.5 billion market. REMOXY targets the $2.5 billion marketplace for long-acting oxycodone. Despite these impressive commercial figures, we believe opioid abuse remains a serious, persistent problem for physicians and patients alike.

 

We own exclusive, worldwide rights to REMOXY. If approved and granted appropriate label claims, we believe REMOXY may have potential to distinguish itself from competitors with:

 

ü

best-in-class abuse-deterrent properties;

ü

true twice-daily dosing;

ü

minimal food effect;

ü

lack of generic drug substitution; and

ü

over 15 years of intellectual property protection.

 

Currently we have no capability to launch or to commercialize our drug products. We continue to review potential launch and commercialization strategies for REMOXY. Options include a potential strategic transaction around all of our drug candidates; a commercial collaboration for REMOXY; or establishing commercial capabilities in-house to launch REMOXY on our own.

 

Abuse-deterrent Formulations of Hydromorphone and Oxymorphone

 

We believe the technology used in REMOXY is a platform that can be applied to the development of ADFs of hydromorphone and oxymorphone, both Schedule II opioids. We have an IND for each of these two ADF drugs candidates in place with the FDA. We own exclusive, worldwide commercial rights with respect to these drug candidates.

 

About FENROCK

 

FENROCK is a trade name for our proprietary, abuse-deterrent pain patch. FENROCK’s active drug ingredient is fentanyl (CII), a highly addictive opioid drug that is up to 50 times more powerful than morphine.

 

Currently marketed transdermal fentanyl patches are typically used to manage severe chronic pain, but are also easily abused and have been blamed for thousands of deaths across the U.S. Fentanyl abuse is dangerous. A single episode of fentanyl abuse can lead to overdose, respiratory depression or death.

 

FENROCK is an early-stage drug candidate. Our goal with FENROCK is to make the fentanyl pain patch difficult to abuse yet provide 72 hours of steady pain relief when used appropriately by patients. We developed FENROCK in-house. We are currently working with outside collaborators on the development of a final formulation of FENROCK. We believe a final formulation will enable us to file an IND with the FDA.

 

We own exclusive, worldwide rights to FENROCK without royalty or milestone obligations to any third party.

 

About PTI-125

 

This small molecule drug candidate offers a promising new approach to treat Alzheimer’s Disease and other neurological disorders. PTI-125, an oral drug, was designed in-house and characterized by outside collaborators. The science that underlies PTI-125 was initially published in The Journal of Neuroscience (2012-32:9773-9784).

 

The National Institutes of Health (NIH) awarded us a $1,725,000 innovation grant in September 2015 to further study this early-stage drug candidate. This grant was awarded to us following an in-depth evaluation of PTI-125 for scientific and technical merit by academic, clinical and industry experts in neurological disorders. The NIH grant award enables us to fund

7

 

 


 

and conduct pre-clinical studies around PTI-125. We expect results of these on-going studies may enable us to file an IND with the FDA. 

 

We own exclusive, worldwide rights to PTI-125 without royalty or milestone obligations to any third party.

 

 

Strategy

 

We began developing ADFs over a decade ago. Since then our vision has remained the same: to develop novel ADF technology that can set a gold standard of abuse-deterrence for opioid drugs. We submitted our first IND for an ADF opioid drug candidate in 2003. At that time, the FDA had no formal guidelines for ADFs, the public was generally unaware of opioid abuse and many prescribing physicians underappreciated the abuse potential of opioid drugs. Today, there is widespread public awareness of opioid drug abuse and FDA has issued formal regulatory guidance for the development of ADFs. Consequently, we believe our original vision for REMOXY – to set a gold standard of abuse-deterrence – is now within reach.

 

Our corporate strategy has changed little over the years: to spend carefully but to keep innovation at the top of our agenda.  Elements of our corporate strategy include:

 

Focus on Clinical Development Stage Products.   We believe this focus will enable us to generate product revenues earlier than if we were focused on early-stage research and discovery activities.

 

Retain Significant Rights to Our Drugs.   We currently retain worldwide commercialization rights to all of our technology and drug candidates in all markets and indications, including REMOXY. In general, we intend to independently develop our drug candidates through late-stage clinical trials.

 

Outsource Key Functions.   We intend to continue to outsource preclinical studies, clinical trials and formulation and manufacturing activities. We believe outsourcing permits significant time savings and allows for more efficient deployment of our resources.

 

Pursue In-licensing or Acquisition Opportunities.   We intend to evaluate promising drug candidates or technologies to further expand our product pipeline. Our in-licensing strategy consists of evaluating clinical or preclinical stage opportunities in therapeutic areas that can benefit from our core expertise in drug development. Such in-licensing or acquisition opportunities may be in pain management or in other therapeutic areas outside of pain management. We believe this element of our corporate strategy could diversify some of the risks inherent in focusing on a single therapeutic area and could also increase our probability of commercial success.

 

We also conduct basic research in collaboration with academic and other partners. Our research and development expenses were $4.9 million in 2013, $7.3 million in 2014 and $9.1 million in 2015.

 

 

Our Intellectual Property

 

We own or license a number of U.S. and foreign patents, patent applications and rights to patents covering our products and technology. We consider the overall protection of our patents and other intellectual property rights to be of material value and act to protect these rights from infringement.

 

We seek to protect our technology by, among other methods, filing and prosecuting U.S. and foreign patents and patent applications with respect to our technology and products and their uses. The focus of our patent strategy is to secure and maintain intellectual property rights to technology for the following categories of our business:

 

·

the technology that forms the basis of REMOXY and our other abuse-deterrent drug candidates;

·

the technologies related to our pre-clinical product candidates; and

·

the manufacture and use of our drug candidates.

 

8

 

 


 

However, we may rely on certain proprietary technologies and know-how that are not patentable. We protect our proprietary information, in part, by the use of confidentiality agreements with our employees, consultants, and certain of our contractors.

 

We plan to prosecute and defend our patent applications, allowed patents, issued patents and proprietary information. Our competitive position and potential future revenues will depend in large part upon our ability to protect our intellectual property from challenges and to enforce our patent rights against potential infringements.

Patents expire, on a country by country basis, at various times depending on various factors, including the filing date of corresponding patent applications. Our patents and the patents we license from third parties include the following issued U.S. Patents:  8,168,217; 8,153,152; 8,147,870;  8,133,507;  8,354,124;  8,415,401; 8,420,120;  8,974,821; 8,945,614; 8,951,556; and 9,233,160.

 

Our issued U.S. patent for REMOXY with the longest patent term extends to 2031. Outside the U.S., our granted patent with the longest patent term for REMOXY extends to 2028. Patents may have their term extended for various reasons including the grant of patent term adjustments, patent term extensions, or supplemental protection certificates, or may have their term shortened for various reasons including by terminal disclaimers. Certain U.S. patent applications and patent applications outside the U.S. are pending.

 

In addition, we use a unique and complex process to manufacture REMOXY. We also protect as trade secrets the significant pharmaceutical know-how and detailed knowledge of a complex supply chain to manufacture REMOXY.

 

REMOXY®  and FENROCK™ are trademarks of Pain Therapeutics, Inc.

 

 

Prior Agreements with Pfizer

 

Between 2005 and 2014, Pfizer paid us a total of approximately $290 million. This includes $155 million in upfront fees, $30 million in milestone payments and $105 million to reimburse expenses we incurred under the Pfizer Agreements.

 

In October 2014, Pfizer provided us with written notice of termination of the Pfizer Agreements. We believe Pfizer terminated its development of REMOXY, in part, to focus on its own ADF drug candidate called ALO-02. Pfizer filed an NDA for ALO-02 shortly after informing us of its intention to discontinue REMOXY. Pfizer’s NDA for ALO-02 is currently under review by the FDA.

 

In April 2015, we announced that we had resumed sole responsibility for REMOXY under the terms of a letter agreement with Pfizer. The letter agreement was entered into within the scope of the previously disclosed provisions of the Collaboration Agreement between us and Pfizer relating to the return of REMOXY. Pfizer has no further obligations to us. We have no further obligations to Pfizer, except that we will owe Pfizer a one-time payment of $200,000, payable at the time REMOXY is approved by the FDA, related to certain commercial manufacturing equipment we purchased from Pfizer.

 

 

Formulation Agreement with Durect Corporation

 

We have an exclusive, worldwide Development and License Agreement, or the Durect Agreement, with Durect to use a patented controlled-release technology that forms the basis for REMOXY and ADFs of oxymorphone and hydromorphone. In 2015, we returned to Durect rights related to ADFs of hydrocodone.

 

We are solely responsible for the clinical development of opioid ADFs under the terms of the Durect Agreement. Durect is responsible for furnishing suitable laboratory facilities, equipment and personnel during pre-clinical phases of development. The performance of pre-clinical activities of a joint responsibility of us and Durect.

Pursuant to the Durect Agreement, we reimburse Durect’s expenses and make milestone payments based on the achievement of certain clinical or regulatory milestones. We paid Durect approximately $38.4 million from the inception of the Durect Agreement to December 31, 2015. We could pay up to another $5.6 million under the Durect Agreement following achievement of certain milestones.

We are obligated to pay Durect royalties on commercial sales of REMOXY, oxymorphone and hydromorphone. These royalties range from 6.0% to 11.5% of net sales, depending on the volume of sales of licensed products in a given calendar year.

 

The Durect Agreement terminates on a country-by-country basis upon the later of the expiration of the last to expire of the patents licensed under such agreement or a certain number of years following first commercial sale in such country. Currently, the last to expire patent covered by such agreement expires by 2031. However, such date may be extended by the issuance of any additional patents pursuant to pending patent applications. We can terminate the Durect Agreement with notice to Durect, and we and Durect can terminate such agreement under certain circumstances, including material breach and insolvency.

 

 

Manufacturing

 

We do not own any manufacturing facilities. We outsource formulation, manufacturing and related activities to third-parties.

 

Our suppliers must comply with current good manufacturing practices, or GMP, enforced by the FDA and other government agencies such as the U.S. Drug Enforcement Administration, or DEA. Our suppliers are subject to unannounced inspection by regulators, including pre-approval inspections by the FDA and the DEA, to ensure they are in strict compliance with government regulations and standards. Our suppliers may be forced to stop producing, storing, shipping or testing our drug products if they fall out of compliance with government regulations and standards.

 

We have no control over our suppliers’ compliance, or lack thereof, with the multitude of regulations and standards that affect our drug products. We cannot control decisions by our suppliers that affect their ability or willingness to continue to supply us on acceptable terms, or at all. 

 

We may not be able to replace a commercial supplier on commercially reasonable terms, or at all. Replacing any of our commercial suppliers would be expensive and time consuming. Further, if REMOXY is approved, our commercial suppliers may encounter difficulties in achieving high volumes of production to satisfy commercial demands. Failure by any of our suppliers to perform as expected could delay or prevent commercialization of REMOXY or result in shortages, cost overruns, or other problems and would materially harm our business.

 

Commercial supply of certain excipients from Durect

 

We will rely on Durect as the sole source of certain excipients in REMOXY. Durect has limited experience manufacturing pharmaceutical products and maintaining GMP-compliant operations. A Pre-Approval Inspection, or PAI, by FDA officials is often integral to the FDA approval process. A PAI is an unannounced evaluation of a manufacturing or test site for readiness for commercial scale manufacturing, conformance with commitments made in an NDA and data integrity. We do not and cannot know whether Durect’s manufacturing or test facilities could pass a PAI inspection related to REMOXY.

 

We rely on Durect to supply to us certain excipients for the REMOXY formulation. Under the Durect Agreement, these excipients are supplied to us at Durect’s cost, plus thirty (30) percent. We currently do not have a long-term commercial supply agreement in place with Durect. We expect that we and Durect will negotiate a supply agreement for these excipients. We may not be able to establish a commercial supply agreement on acceptable terms. Until a commercial supply agreement is in place with Durect, we expect to obtain excipients from Durect via individual purchase orders.

 

If we receive marketing approval for REMOXY, Durect may need to materially expand its manufacturing capacity. Durect may not be able to increase its manufacturing capacity for REMOXY in a timely or economic manner, or at all. Moreover, significant scale up of manufacturing will require additional validation studies, which are subject to FDA review and approval.

 

Commercial supply of oxycodone with Noramco

 

We expect to rely on Noramco as the sole source of the oxycodone base used in REMOXY. We currently do not have a long-term commercial supply agreement in place with Noramco. We expect to negotiate with Noramco a commercial supply

10

 

 


 

agreement to supply us with oxycodone base. We may not be able to establish a commercial supply agreement on acceptable terms, or at all. Until we have a commercial supply agreement in place with Noramco, we expect to obtain oxycodone base from Noramco via individual purchase orders.

 

Commercial drug supply agreement with Mallinckrodt

 

We expect to rely on Mallinckrodt as the sole-source drug product manufacturer of REMOXY pursuant to an Amended and Restated Commercial Supply Agreement, or the Mallinckrodt Agreement. Pfizer and Mallinckrodt established the Mallinckrodt Agreement when Pfizer was responsible for commercialization of REMOXY. Pfizer assigned the Mallinckrodt Agreement to us in connection with the termination of the Pfizer Agreements. In addition to drug product manufacturing, Mallinckrodt is responsible for sourcing excipients in REMOXY other than those provided by the Durect Agreement. We plan to have Mallinckrodt manufacture pre-validation and commercial validation batches of REMOXY in 2016.

 

Other commercial manufacturing and supply agreements

 

We will rely on third-parties to conduct certain quality control and assurance testing, shipping or storage of REMOXY.

 

 

Government Regulation

 

Regulation by governmental authorities in the United States and other countries is a significant factor in the manufacture and marketing of pharmaceuticals and in our ongoing research and development activities. All of our products will require regulatory approval by governmental agencies prior to commercialization. In particular, human therapeutic products are subject to rigorous preclinical testing and clinical trials and other pre-marketing approval requirements by the FDA and regulatory authorities in other countries. In the United States, various federal, and in some cases state, statutes and regulations also govern or impact the manufacturing, safety, labeling, storage, record keeping and marketing of our products. The lengthy process of seeking required approvals and the continuing need for compliance with applicable statutes and regulations require us to spend substantial resources. Regulatory approval, when and if obtained, may be limited in scope which may significantly limit the indicated uses for which our products may be marketed. Further, approved drugs, as well as their manufacturers, are subject to ongoing review and discovery of previously unknown problems with such products that may result in restrictions on their manufacture, sale or use or in their withdrawal from the market.

 

Applicable FDA regulations require the filing of an NDA or a Biologic License Application, or BLA and approval by the FDA prior to commercialization of any of our drug candidates in the United States.

 

The Drug Approval Process

 

We will be required to complete several activities before we can market any of our drug candidates for human use in the United States, including:

 

·

preclinical studies;

·

submission to the FDA of an IND which must become effective before human clinical trials commence;

·

adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug candidate;

·

submission to the FDA of an NDA; and

·

FDA approval of the NDA prior to any commercial sale or shipment of the drug.

 

Preclinical tests include laboratory evaluation of product chemistry and formulation, as well as animal studies to assess the potential safety of the product. Preclinical safety tests must be conducted by laboratories that comply with FDA regulations regarding Good Laboratory Practice. We submitted the results of preclinical tests to the FDA as part of our INDs prior to commencing clinical trials. We may be required to conduct additional toxicology studies.

 

Based on preclinical testing, an IND is filed with the FDA to begin human testing of the drug in the United States. The IND becomes effective if not rejected by the FDA within 30 days. The IND must indicate the results of previous experiments, how, where and by whom the new clinical trials will be conducted, the chemical structure of the compound, the method by which it is believed to work in the human body, any toxic effects of the compound found in the animal studies and how the compound is manufactured. All clinical trials must be conducted in accordance with Good Clinical Practice. In addition, an

11

 

 


 

Institutional Review Board, or IRB, generally comprised of physicians at the hospital or clinic where the proposed clinical trials will be conducted, must review and approve the IND. The IRB also continues to monitor the clinical trial. We must submit progress reports detailing the results of the clinical trials to the FDA at least annually. In addition, the FDA may, at any time during the 30-day period or at any time thereafter, impose a clinical hold on proposed or ongoing clinical trials. If the FDA imposes a clinical hold, clinical trials under the IND cannot commence or recommence without FDA authorization and then only under terms authorized by the FDA. An FDA imposed clinical hold on an IND application can result in substantial delay and large, unforeseen expenses, and it may cancel the viability of developing a new drug candidate in the United States.

 

Clinical trials are typically conducted in three sequential phases that may overlap. Phase I clinical trials typically study a drug’s safety profile, and may include the safe dosage range. Phase I clinical trials also determine how a drug is absorbed, distributed, metabolized and excreted by the body, and the duration of its action. In addition, we may, to the extent feasible, assess early indicators of a drug’s efficacy in our Phase I clinical trials. In Phase II clinical trials, controlled studies are conducted on volunteer patients with the targeted disease or condition. The primary purpose of these tests is to evaluate the effectiveness of the drug on the volunteer patients as well as to determine a drug’s side effect profile. These clinical trials may be conducted concurrently with Phase I clinical trials. In addition, Phase I/II clinical trials may be conducted to evaluate not only the efficacy of the drug on the patient population, but also its safety. During Phase III clinical trials, the drug is studied in an expanded patient population and in multiple sites. Physicians monitor the patients to determine efficacy and to observe and report adverse events that may result from use of the drug.

 

Our clinical trials are designed to produce clinical information about how our drugs perform compared to placebo or compared to existing drugs where appropriate. We have designed most Phase II and Phase III clinical trials to date as randomized, double-blind, placebo-controlled, dose-ranging studies. A randomized clinical trial is one in which patients are randomly assigned to the various study treatment arms. A double-blind clinical trial is one in which the patient, the physician and our trial monitor are unaware if the patient is receiving placebo or study drug in order to preserve the integrity of the clinical trial and reduce bias. A placebo-controlled clinical trial is one in which a subset of patients is purposefully given inactive medication.

 

We may not successfully complete Phase I, Phase II or Phase III clinical trials within any specified time period, or at all, with respect to any of our drug candidates. Furthermore, we or the FDA may suspend clinical trials at any time in response to concerns that participants are exposed to an unacceptable health risk.

 

After the completion of clinical trials, if there is substantial evidence that the drug is safe and effective, an NDA is filed with the FDA. The NDA must contain all of the information on the drug gathered to that date, including data from the clinical trials. NDAs often exceed 100,000 pages in length.

 

The FDA may request additional information before accepting an NDA. In such an event, the NDA must be resubmitted with the additional information and, again, is subject to review before filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the Federal Food, Drug and Cosmetic Act, the FDA reviews the NDA and responds to the applicant. The review process is typically extended for significant amounts of time by the FDA’s requests for additional information or clarification regarding information already provided in the submission. The FDA may refer the application to an appropriate advisory committee, typically a panel of clinicians, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee.

 

If the FDA’s evaluations of the NDA and the manufacturing facilities are favorable, the FDA may issue either a Complete Response Letter indicating either an approval or may identify conditions that must be met in order to secure final approval of the NDA. When and if those conditions have been met to the FDA’s satisfaction, the FDA will issue an approval letter, authorizing commercial marketing of the drug for certain indications. If the FDA’s evaluation of the NDA submission or manufacturing facilities is not favorable, the FDA may refuse to approve the NDA or issue a not approvable letter.

 

If the FDA approves the NDA, the drug becomes available for physicians to prescribe. Periodic reports must be submitted to the FDA, including descriptions of any reported adverse reactions. The FDA may request additional post-marketing studies, or Phase IV clinical trials, to evaluate long-term effects of the approved drug.

Other Regulatory Requirements

 

The FDA mandates that drugs be manufactured in conformity with current GMP. If the FDA approves any of our drug candidates, we will be subject to requirements for labeling, advertising, record keeping and adverse experience reporting. Failure to comply with these requirements could result, among other things, in suspension of regulatory approval, recalls, injunctions or civil or criminal sanctions. We may also be subject to regulations under other federal, state, and local laws, including the Occupational Safety and Health Act, the Environmental Protection Act, the Clean Air Act, national restrictions on technology transfer, and import, export, and customs regulations. In addition, any of our products that contain narcotics will be subject to DEA regulations relating to manufacturing, storage, distribution and physician prescribing procedures. It is possible that any portion of the regulatory framework under which we operate may change and that such change could have a negative impact on our current and anticipated operations.

 

The Controlled Substances Act imposes various registration, record-keeping and reporting requirements, procurement and manufacturing quotas, labeling and packaging requirements, security controls and a restriction on prescription refills on certain pharmaceutical products. A principal factor in determining the particular requirements, if any, applicable to a product is its actual or potential abuse profile. The DEA regulates chemical compounds as Schedule I, II, III, IV or V substances, with Schedule I substances considered to present the highest risk of substance abuse and Schedule V substances the lowest risk. Any of our drug candidates that contain a scheduled substance will be subject to regulation by the DEA.

 

 

Competition

 

Our success will depend, in part, upon our ability to achieve market share at the expense of existing and established and future products in the relevant target markets. Existing and future products, therapies, technological approaches or delivery systems will compete directly with our products. Competing products may provide greater therapeutic benefits for a specific indication, or may offer comparable performance at a lower cost. Companies that currently sell generic or proprietary opioid formulations may include, but are not limited to, Roxane Laboratories, Purdue Pharma, Mylan, Pfizer, Abbott Laboratories, Endo Pharmaceuticals, Teva Pharmaceuticals, Elkins-Sinn, Watson Laboratories, Ortho-McNeil Pharmaceutical and Forest Pharmaceuticals. Collegium Pharmaceuticals may in the future commercialize an abuse-deterrent oxycodone formulation. Pfizer’s NDA for ALO-02, an abuse-deterrent oxycodone formulation, is currently under review by the FDA. Alternative technologies are being developed to address the issue of abuse or misuse of opioid painkillers or increase opioid potency, as well as alternatives to opioid therapy for pain management, several of which are in clinical trials or are awaiting approval from the FDA.

 

We compete with fully integrated pharmaceutical companies, smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Many of these competitors have opioid drugs already approved by the FDA or in development and operate larger research and development programs in these fields than we do. In addition, many of these competitors, either alone or together with their collaborative partners, have substantially greater financial resources than we do, as well as significantly greater experience in:

 

·

developing drugs;

·

undertaking preclinical testing and human clinical trials;

·

obtaining FDA and other regulatory approvals of drugs; 

·

formulating and manufacturing drugs; and

·

launching, marketing, distributing and selling drugs.

 

Developments by competitors may render our drug candidates or technologies obsolete or non-competitive. We also compete with these companies for qualified personnel and opportunities for product acquisitions, joint ventures or other strategic alliances.

Item 1A.Risk Factors

 

Our future operating results may vary substantially from anticipated results due to a number of factors, many of which are beyond our control. The following discussion highlights some of these factors and the possible impact of these factors on future results of operations. You should carefully consider these factors before making an investment decision. If any of the following factors actually occur, our business, financial condition or results of operations could be harmed. In that case, the price of our common stock could decline, and you could experience losses on your investment in our common stock.

 

Clinical and Regulatory Risks

If we fail to obtain the necessary regulatory approvals, or if such approvals are limited, we and our collaborators will not be allowed to commercialize our drug candidates, and we will not generate product revenues.

 

Satisfaction of all regulatory requirements for commercialization of a drug candidate typically takes many years, is dependent upon the type, complexity and novelty of the drug candidate, and requires the expenditure of substantial resources for research and development. In December 2008, we received from the FDA a Complete Response Letter for the NDA for REMOXY. In this Complete Response Letter, the FDA indicated that additional non-clinical data was required to support the approval of REMOXY. However, the FDA did not request or recommend additional clinical efficacy studies prior to approval. In March 2009, King assumed sole responsibility for the regulatory approval of REMOXY. In December 2010, King resubmitted the NDA for REMOXY. In June 2011, we and Pfizer announced that King received a Complete Response Letter from the FDA in response to King’s resubmission of the REMOXY NDA. The FDA’s Complete Response Letter raised concerns related to, among other matters, the Chemistry, Manufacturing, and Controls section of the NDA for REMOXY. Certain drug lots showed inconsistent release performance during in vitro testing. Pfizer completed work designed to address the June 2011 Complete Response Letter. On April 21, 2015, we announced that we resumed responsibility for REMOXY under the terms of a letter agreement with Pfizer. The letter agreement was entered into within the scope of the previously disclosed provisions of the Collaboration Agreement between us and Pfizer relating to the return of REMOXY.

 

We believe Pfizer has now transferred to us its data, materials, capital equipment and other assets related to REMOXY. Pfizer and the FDA had discussed and agreed to a regulatory plan to refile the NDA for REMOXY. The FDA has agreed that we may follow this plan to prepare the NDA for REMOXY. We plan to refile the NDA for REMOXY in March 2016. We expect our refiling will generally follow the plan agreed to with the FDA. We have recently reviewed stability data for REMOXY through 18 months that we believe supports re-filing the NDA. We plan to continue to collect additional stability data for REMOXY and plan to propose 24-month dating in the label. We have substantially completed certain non-clinical

14

 

 


 

activities, reviewed data from these activities to support the NDA resubmission and completed final study reports on human abuse potential and other studies previously conducted by Pfizer.

 

We expect the FDA will accept the filing of the NDA for REMOXY. Acceptance of the filing does not suggest that the FDA has completed any aspect of its review of the NDA. We believe the FDA may complete its review of the NDA for REMOXY within six months of the date of our resubmission.

 

There can be no assurance that the FDA will accept an NDA for REMOXY or will approve an NDA for REMOXY or that the FDA will not require submission of additional clinical or non-clinical data. Obtaining data from such studies (even if completed) that is insufficient to support approval of REMOXY, or any adverse decisions by the FDA (including any decision by the FDA to require additional clinical or non-clinical data) may significantly delay or prevent the potential approval of REMOXY.

 

Our research and clinical approaches may not lead to drugs that the FDA considers safe for humans and effective for indicated uses we are studying. The FDA may require additional studies, in which case we or our collaborators would have to expend additional time and resources and would likely delay the date of potentially receiving regulatory approval. The approval process may also be delayed by changes in government regulation, future legislation or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory approvals would:

·

delay commercialization of, and product revenues from, our drug candidates; and

·

diminish the competitive advantages that we may have otherwise enjoyed, which would have an adverse effect on our operating results and financial condition.

Even if we or our collaborators comply with all FDA regulatory requirements, our drug candidates may never obtain regulatory approval. If we or our collaborators fail to obtain regulatory approval for any of our drug candidates we will have fewer commercial products, if any, and corresponding lower product revenues, if any. Even if our drug candidates receive regulatory approval, such approval may involve limitations on the indications and conditions of use or marketing claims for our products. Further, later discovery of previously unknown problems or adverse events could result in additional regulatory restrictions, including withdrawal of products. The FDA may also require us or our collaborators to commit to perform lengthy Phase IV post-approval clinical efficacy or safety studies. Our expending additional resources on such trials would have an adverse effect on our operating results and financial condition.

In jurisdictions outside the United States, we must receive marketing authorizations from the appropriate regulatory authorities before commercializing our drugs. Regulatory approval processes outside the United States generally include all of the aforementioned requirements and risks associated with FDA approval.

If we are unable to design, conduct and complete preclinical and clinical trials successfully, our drug candidates will not be able to receive regulatory approval.

In order to obtain FDA approval for any of our drug candidates, we must submit to the FDA an NDA that demonstrates with substantive evidence that the drug candidate is both safe and effective in humans for its intended use. This demonstration requires significant research and animal tests, which are referred to as preclinical studies, as well as human tests, which are referred to as clinical trials.

Preclinical studies may not provide results we believe are sufficient to support the filing of an IND. Success in early preclinical studies does not ensure success in later preclinical or clinical studies. The FDA may disagree with the design of our preclinical studies or our interpretations of data from preclinical studies. The FDA may not accept an IND for our product candidate and may require additional preclinical studies to support the filing of an IND.

Success in preclinical studies and early clinical trials does not ensure that later clinical trials will be successful. Results from Phase I clinical programs may not support moving a drug candidate to Phase II or Phase III clinical trials. Phase III clinical trials may not demonstrate the safety or efficacy of our drug candidates. Results of later clinical trials may not replicate the results of prior clinical trials and preclinical studies. Even if the results of Phase III clinical trials are positive, we or our collaborators may have to commit substantial time and additional resources to conducting further preclinical studies and clinical trials before obtaining FDA approval for any of our drug candidates.

Clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous requirements. The clinical trial process also consumes a significant amount of time. Furthermore, if patients in clinical trials

15

 

 


 

suffer drug-related adverse reactions during the course of such clinical trials, or if we, our collaborators or the FDA believe that participating patients are being exposed to unacceptable health risks, such clinical trials will have to be suspended or terminated. Failure can occur at any stage of the clinical trials, and we or our collaborators could encounter problems that cause abandonment or repetition of clinical trials.

Clinical trials with REMOXY and our potential future clinical trials for other drug candidates for treatment of pain measure clinical symptoms, such as pain and physical dependence, that are not biologically measurable. The success in these clinical trials depends on reaching statistically significant changes in patients’ symptoms based on clinician-rated scales. Due in part to a lack of consensus on standardized processes for assessing clinical outcomes, these scores may or may not be reliable, useful or acceptable to regulatory agencies.

In addition, completion of clinical trials can be delayed by numerous factors, including:

·

delays in identifying and agreeing on acceptable terms with prospective clinical trial sites;

·

slower than expected rates of patient recruitment and enrollment;

·

unanticipated patient dropout rates;

·

increases in time required to complete monitoring of patients during or after participation in a clinical trial; and

·

unexpected need for additional patient-related data.

Any of these delays could significantly impact the timing, approval and commercialization of our drug candidates and could significantly increase our overall costs of drug development.

Even if clinical trials are completed as planned, their results may not support expectations or intended marketing claims. The clinical trials process may fail to demonstrate that our drug candidates are safe and effective for indicated uses. Such failure would cause us to abandon a drug candidate and could delay development of other drug candidates.

Clinical trial designs that were discussed with regulatory authorities prior to their commencement may subsequently be considered insufficient for approval at the time of application for regulatory approval.

We discuss with and obtain guidance from regulatory authorities on certain of our clinical development activities. With the exception of our Special Protocol Assessment, or SPA, such as the one we completed with the FDA with respect to the Phase III clinical trial for REMOXY, these discussions are not binding obligations on the part of regulatory authorities.

Regulatory authorities may revise previous guidance or decide to ignore previous guidance at any time during the course of our clinical activities or after the completion of our clinical trials. Even with successful clinical safety and efficacy data, including such data from a clinical trial conducted pursuant to an SPA, we or our collaborators may be required to conduct additional, expensive clinical trials to obtain regulatory approval.

Developments by competitors may establish standards of care that affect our ability to conduct our clinical trials as planned.

We have conducted clinical trials of our drug candidates comparing our drug candidates to both placebo and other approved drugs. Changes in standards related to clinical trial design could affect our ability to design and conduct clinical trials as planned. For example, regulatory authorities may not allow us to compare our drug candidates to placebo in a particular clinical indication where approved products are available. In that case, both the cost and the amount of time required to conduct a clinical trial could increase.

The DEA limits the availability of the active ingredients in certain of our current drug candidates and, as a result, quotas for these ingredients may not be sufficient to complete clinical trials, or to meet commercial demand, or may result in clinical delays.

The DEA regulates chemical compounds as Schedule I, II, III, IV or V substances, with Schedule I substances considered to present the highest risk of substance abuse and Schedule V substances the lowest risk. Certain active ingredients in our current drug candidates, such as oxycodone, are listed by the DEA as Schedule II under the Controlled Substances Act of 1970. Consequently, their manufacture, research, shipment, storage, sale and use are subject to a high degree of oversight and regulation. For example, all Schedule II drug prescriptions must be signed by a physician, physically presented to a pharmacist and may not be refilled without a new prescription. Furthermore, the amount of Schedule II substances that can be obtained

16

 

 


 

for clinical trials and commercial distribution is limited by the DEA and quotas for these substances may not be sufficient to complete clinical trials or meet commercial demand. There is a risk that DEA regulations may interfere with the supply of the drugs used in clinical trials for our product candidates, and, in the future, the ability to produce and distribute our products in the volume needed to meet commercial demand.

Conducting clinical trials of our drug candidates or potential commercial sales of a drug candidate may expose us to expensive product liability claims and we may not be able to maintain product liability insurance on reasonable terms or at all.

The risk of product liability is inherent in the testing of pharmaceutical products. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit or terminate testing of one or more of our drug candidates. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of our drug candidates. We currently carry clinical trial insurance but do not carry product liability insurance. If we successfully commercialize one or more of our drug candidates, we may face product liability claims, regardless of FDA approval for commercial manufacturing and sale. We may not be able to obtain such insurance at a reasonable cost, if at all. Even if our agreements with any current or future corporate collaborators entitle us to indemnification against product liability losses, such indemnification may not be available or adequate should any claim arise.

If our drug candidates receive regulatory approval, we and our collaborators will be subject to ongoing FDA obligations and continued regulatory review, such as continued safety reporting requirements, and we and our collaborators may also be subject to additional FDA post-marketing obligations or new regulations, all of which may result in significant expense and limit our and our collaborators’ ability to commercialize our potential drugs.

Any regulatory approvals that our drug candidates receive may also be subject to limitations on the indicated uses for which the drug may be marketed or contain requirements for potentially costly post-marketing follow-up studies. In addition, if the FDA approves any of our drug candidates, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record keeping for the drug will be subject to extensive regulatory requirements. The subsequent discovery of previously unknown problems with the drug, including but not limited to adverse events of unanticipated severity or frequency, or the discovery that adverse events previously observed in preclinical research or clinical trials that were believed to be minor actually constitute much more serious problems, may result in restrictions on the marketing of the drug, and could include withdrawal of the drug from the market.

The FDA’s policies may change and additional government regulations may be enacted that could prevent or delay regulatory approval of our drug candidates. We cannot predict the likelihood, nature or extent of adverse government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are not able to maintain regulatory compliance, we may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. Any of these events could prevent us from marketing our drugs and our business could suffer.

We may not be able to successfully develop or commercialize FENROCK, a proprietary abuse-deterrent transdermal pain patch (fentanyl), designed to prevent common methods of abuse of fentanyl.

We have no history of developing transdermal patches. We do not know whether any of our planned development activities for FENROCK will result in approval of such drug candidate by the FDA, or, if FENROCK is approved, it will be a commercially viable product.

 

 

Risks Relating to our Collaboration Agreements

If Pfizer did not transfer to us all data and documentation or the quality of the data and documentation transferred is insufficient, our ability to resubmit an NDA for REMOXY will be negatively impacted and our business will suffer.

 

On April 21, 2015, we announced that we resumed responsibility for REMOXY under the terms of a letter agreement with Pfizer. The letter agreement was entered into within the scope of the previously disclosed provisions of the Collaboration Agreement between us and Pfizer relating to the return of REMOXY.

 

17

 

 


 

We believe Pfizer has transferred to us data, materials, capital equipment and other assets related to REMOXY. In preparing to resubmit the NDA for REMOXY, we may find that there are additional data, materials or agreements that Pfizer should have transferred to us. If Pfizer did not meet its obligations to transfer all such materials or if the quality of the data and documentation transferred is insufficient, we would be significantly delayed in our ability to resubmit an NDA for REMOXY, and may need to conduct further development activities or clinical trials to prepare any potential resubmission. As a result, any further development, regulatory approval and product introduction for REMOXY would be delayed or prevented and our business would suffer.

If outside collaborators fail to devote sufficient time and resources to drug development programs related to our product candidates, or if their performance is substandard, regulatory submissions and introductions for our products may be delayed.

We rely on Durect as the sole-source provider of certain components of REMOXY. Durect’s failure for any reason to provide these components could result in delays or failures in product testing or delivery, cost overruns or other problems that could materially harm our business.

We depend on independent investigators and collaborators, such as universities and medical institutions, to conduct our clinical trials under agreements with us. These investigators and collaborators are not our employees, and we cannot control the amount or timing of resources that they devote to our programs. They may not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such activities ourselves. If these investigators or collaborators fail to devote sufficient time and resources to our drug development programs, or if their performance is substandard, the approval of our regulatory submissions and our introductions of new drugs will be delayed or prevented.

Our collaborators may also have relationships with other commercial entities, some of which may compete with us. If outside collaborators assist our competitors to our detriment, the approval of our regulatory submissions will be delayed and the sales from our products, if any are commercialized, will be less than expected.

If we fail to enter into or maintain collaboration agreements and licenses for REMOXY and other drugs designed to reduce potential risks of unintended use, we may have to reduce or delay our drug candidate development.

Our plan for developing, manufacturing and commercializing REMOXY currently requires us to successfully maintain our license from Durect. If we are unable to meet the obligations necessary to maintain our license with Durect for one or more potential products we may lose the rights to utilize Durect’s technology for such potential products, our potential future revenues may suffer and we may have to reduce or delay development of our other drug candidates. In addition, we expect to seek a new corporate collaborator with respect to REMOXY. If we do not enter into a new collaboration with respect to the continued development and potential commercialization of REMOXY, we will be required to undertake and fund such activities ourselves and may need to seek additional capital (which may not be available on acceptable terms, if at all), personnel or other resources. If we are not successful in such efforts, development and commercialization of REMOXY and our other drug candidates would be delayed or prevented, and our business would suffer.

We may not succeed at in-licensing drug candidates or technologies to expand our product pipeline.

We may not successfully in-license drug candidates or technologies to expand our product pipeline. The number of such candidates and technologies is limited. Competition among large pharmaceutical companies and biopharmaceutical companies for promising drug candidates and technologies is intense because such companies generally desire to expand their product pipelines through in-licensing. If we fail to carry out such in-licensing and expand our product pipeline, our potential future revenues may suffer.

Our collaborative agreements may not succeed or may give rise to disputes over intellectual property, disputes concerning the scope of collaboration activities or other issues.

Our collaborative agreements with third parties, such as our license agreement with Durect, are generally complex and contain provisions that could give rise to legal disputes, including potential disputes concerning ownership of intellectual property under collaborations or disputes concerning the scope of collaboration activities. Such disputes can delay or prevent the development of potential new drug products, or can lead to lengthy, expensive litigation or arbitration. Other factors relating to collaborative agreements may adversely affect our business, including:

·

the development of parallel products by our collaborators or by a competitor;

18

 

 


 

·

arrangements with collaborative partners that limit or preclude us from developing certain products or technologies;

·

premature termination of a collaborative or license agreement; or

·

failure by a collaborative partner to provide required funding, to devote sufficient resources to the development of or legal defense of our potential products or to provide data or other information to us as required by our collaborative agreements.

 

 

Risks Relating to Commercialization

If physicians and patients do not accept and use our drugs, we will not achieve sufficient product revenues and our business will suffer.

Even if the FDA approves our drugs, physicians and patients may not accept and use them. Acceptance and use of our drugs will depend on a number of factors including:

·

when the drug is launched into the market and related competition;

·

approved label claims;

·

perceptions by members of the healthcare community, including physicians, about the safety and effectiveness of our drugs, and, in particular, the effectiveness of REMOXY in reducing potential risks of unintended use;

·

perceptions by physicians regarding the cost benefit of REMOXY in reducing potential risks of unintended use;

·

published studies demonstrating the cost-effectiveness of our drugs relative to competing products;

·

availability of reimbursement for our products from government or healthcare payers;

·

our or our collaborators’ ability to implement a risk management plan prior to the distribution of any Schedule II drug; and

·

effectiveness of marketing and distribution efforts by us and other licensees and distributors.

Because we expect to rely on sales generated by our current lead drug candidates for substantially all of our revenues for the foreseeable future, the failure of any of these drugs to find market acceptance would harm our business and could require us to seek additional financing.

We currently have no in-house capabilities to commercialize our drug products and if we are unable to develop our own sales, marketing and distribution capabilities, or if we are not successful in contracting with third parties for these services on favorable terms, or at all, our product revenues could be disappointing.

We currently have no sales, marketing or distribution capabilities. We have not established commercial strategies regarding any of our product candidates, including REMOXY. In order to commercialize our products, if any approved by the FDA, we will either have to develop such capabilities internally or collaborate with third parties who can perform these services for us.

If we decide to commercialize any of our drugs ourselves, we may not be able to

·

hire and retain the necessary experienced personnel;

·

build sales, marketing and distribution operations in a cost effective manner which are capable of successfully launching new drugs;

·

obtain access to adequate numbers of physicians to prescribe our products; or

·

generate sufficient product revenues.

In addition, establishing such operations on our own will take time and involve significant expense. If our commercial operations lack complementary products, we may not be able to compete in a cost effective manner with competitors with more products to sell. If we engage third-party collaborators to perform any commercial operations, our future revenues may depend significantly upon the performance of those collaborators.

If we decide to enter into new co-promotion or other licensing arrangements with third parties, we may be unable to locate acceptable collaborators because the number of potential collaborators is limited and because of competition from others for

19

 

 


 

similar alliances with potential collaborators. Even if we are able to identify one or more acceptable new collaborators, we may not be able to enter into any collaborative arrangements on favorable terms, or at all.

In addition, due to the nature of the market for our drug candidates, it may be necessary for us to license all or substantially all of our drug candidates to a single collaborator, thereby eliminating our opportunity to commercialize these other products independently. If we enter into any such new collaborative arrangements, our revenues are likely to be lower than if we marketed and sold our products ourselves.

In addition, any revenues we receive would depend upon our collaborators’ efforts which may not be adequate due to lack of attention or resource commitments, management turnover, change of strategic focus, business combinations or other factors outside of our control. Depending upon the terms of our collaboration, the remedies we have against an under-performing collaborator may be limited. If we were to terminate the relationship, it may be difficult or impossible to find a replacement collaborator on acceptable terms, or at all.

The science of abuse-deterrence is relatively new.

The analytical, clinical, and statistical methods for evaluating abuse-deterrent technologies and study results are new and rapidly evolving. Although we believe the FDA will take a flexible, adaptive approach to the evaluation and labeling of potentially abuse-deterrent products, such as REMOXY, we cannot be certain that our interpretation of abuse-deterrent data for REMOXY is consistent with the views of the FDA. In our opinion, the FDA has limited data correlating the potentially abuse-deterrent properties of certain opioid drug products, such as REMOXY, with actual reduction in abuse or adverse events associated with abuse. In addition, the FDA has stated it is not able to provide specific guidance on the magnitude of effect that would be sufficient to support any particular type of label claim for abuse-deterrence.

In the United States, our ability to market and promote REMOXY and its abuse-deterrent features will be determined by FDA-approved labeling.

The commercial success of REMOXY and certain of our other product candidates will depend upon our ability to obtain FDA-approved labeling describing their abuse-deterrent features. Our failure to achieve FDA approval of product labeling containing such information will prevent us from advertising and promoting the abuse-deterrent features of our product candidates in order to differentiate them from other similar products. This would make our products less competitive in the market.

Abuse-deterrent label claims for our products may not be broad enough to demonstrate a substantial benefit to health care providers and patients.

FDA approval is required in order to make claims that a product has an abuse-deterrent effect. In April 2015, the FDA published final guidance with regard to the evaluation and labeling of abuse-deterrent opioids. The guidance provides direction as to the studies and data required for obtaining abuse-deterrent claims in a product label. FDA guidance describes three categories of pre-market studies that may lead to an abuse-deterrent claim:

Category 1 – laboratory manipulation and extraction studies;

Category 2 – pharmacokinetic studies; and

Category 3 – human abuse potential studies.

 

According to FDA guidance, label claims for abuse-deterrence should describe the product’s specific abuse-deterrent properties as well as the specific routes of abuse that the product has been developed to deter. When data predict or show that a product’s potentially abuse-deterrent properties can be expected to, or actually do, result in a significant reduction in that product’s abuse potential, these data, together with an accurate characterization of what the data mean, may be included in product labeling.

 

If a product is approved by the FDA to include such claims in its label, the applicant may use the approved labeling information about the abuse-deterrent features of the product in its marketing efforts to physicians.

Although we intend to provide data to the FDA to support approval of abuse-deterrence label claims for REMOXY, there can be no assurance that REMOXY or any of our other product candidates will receive FDA-approved labeling that describes the abuse-deterrent features of such products. The FDA may find that our studies and data do not support abuse-deterrent labeling or that our product candidates do not provide substantial abuse-deterrence because, for example, their deterrence mechanisms do not address the way they are most likely to be abused. Further, the FDA is not required to follow its guidance

20

 

 


 

and could change this guidance, which could require us to conduct additional studies or generate additional data. If the FDA does not approve abuse-deterrent labeling, we will not be able to promote such products based on their abuse-deterrent features and our business may suffer.

Even if we do receive FDA approval for abuse-deterrent claims, the claims may not be broad enough to demonstrate a substantial benefit to health care providers and patients. For instance, the claims may not encompass the more common forms of abuse for products like our product candidates. Moreover, continued investigation in Phase 4 studies following product approval, if required, is expensive and may not support the continued use of abuse-deterrent claims.

If we cannot compete successfully for market share against other drug companies, we may not achieve sufficient product revenues and our business will suffer.

The market for our drug candidates is characterized by intense competition and rapid technological advances. If our drug candidates receive FDA approval, they will compete with a number of existing and future drugs and therapies developed, manufactured and marketed by others. Existing or future competing products may provide greater therapeutic convenience or clinical or other benefits for a specific indication than our products, or may offer comparable performance at a lower cost. If our products are unable to capture and maintain market share, we may not achieve sufficient product revenues and our business will suffer.

We and our collaborators will compete for market share against fully integrated pharmaceutical companies or other companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Many of these competitors have drugs already approved or drug candidates in development that will or may compete against our approved drug candidates. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research and development programs and have substantially greater financial resources than we do, as well as significantly greater experience in:

·

developing drugs;

·

conducting preclinical testing and human clinical trials;

·

obtaining FDA and other regulatory approvals of drugs;

·

formulating and manufacturing drugs; and

·

launching, marketing, distributing and selling drugs.

If we fail to obtain acceptable prices or an adequate level of reimbursement for our products from healthcare payers, our ability to generate product revenues will be diminished.

Our ability to commercialize drugs we (alone or with other collaborators) may develop will depend in part on the extent to which reimbursement can be obtained for such drugs from:

·

government and health administration authorities;

·

private health maintenance organizations and health insurers; and

·

other healthcare payers.

Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers, including Medicare, health maintenance organizations and managed care organizations, are challenging the prices charged for medical products and services and/or are seeking pharmacoeconomic data to justify formulary acceptance and reimbursement practices. We currently have not generated pharmacoeconomic data on any of our drug candidates. Government and other healthcare payers increasingly are attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs, and by refusing, in some cases, to provide coverage for uses of approved products for disease indications for which the FDA has or has not granted labeling approval. Adequate third-party insurance coverage may not be available to patients for any products we discover and develop, alone or with collaborators. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for our products, market acceptance of our drug candidates could be limited.

 

21

 

 


 

Enacted and future legislation may increase the difficulty and cost for us to commercialize our product candidates and may reduce the prices we are able to obtain for our product candidates.

Legislative and regulatory changes and future changes regarding the healthcare system could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities or affect our ability to profitably sell any product candidates for which we obtain marketing approval.

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the Medicare Modernization Act, established the Medicare Part D program and provided authority for limiting the number of drugs that will be covered in any therapeutic class thereunder. The Medicare Modernization Act, including its cost reduction initiatives, could limit the coverage and reimbursement rate that we receive for any of our approved products. Private payors may follow Medicare coverage policies and payment limitations in setting their own reimbursement rates resulting in similar limits in payments from private payors.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the Affordable Care Act, among other things, imposes a significant annual fee on companies that manufacture or import branded prescription drug products. It also contains substantial provisions intended to, among other things, broaden access to health insurance, reduce or constrain the growth of health care spending, enhance remedies against healthcare fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, and impose additional health policy reforms, any of which could have a material adverse effect on our business. A significant number of provisions are not yet, or have only recently become, effective, but the Affordable Care Act may result in downward pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs.

The Affordable Care Act, as well as other healthcare reform measures that have been and may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved product, and could seriously harm our future revenues. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may compromise our ability to generate revenue, attain profitability or commercialize our products.

The Affordable Care Act is a highly complex piece of legislation that continues to evolve. We do not and cannot understand or anticipate the full impact and potential implications of the Affordable Care Act on our business or on our drugs.

Even if we are able to commercialize any of our product candidates, our products may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which could have a material adverse effect on our business.

Our ability to commercialize any products successfully will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, determine which medications they will cover and establish reimbursement levels. 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 medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be and whether it will be satisfactory. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or reimbursement is available only to limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also be insufficient to cover our costs and may only be temporary. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by

22

 

 


 

mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable reimbursement rates from both government-funded and private payors for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Public concern over the abuse of opioids, including law enforcement concerns over diversion of opioid and regulatory efforts to combat abuse, could decrease the potential market for our product candidates.

Media stories regarding prescription drug abuse and the diversion of opioids and other controlled substances are commonplace. Law enforcement and regulatory agencies may apply policies that seek to limit the availability of opioids. Such efforts may inhibit our ability to commercialize our product candidates. Aggressive enforcement and unfavorable publicity regarding, for example, the use or misuse of oxycodone or other opioid drugs; the limitations of ADFs; the ability of drug abusers to discover previously unknown ways to abuse our products; public inquiries and investigations into prescription drug abuse; litigation; or regulatory activity regarding sales, marketing, distribution or storage of opioid drugs could have a material adverse effect on our reputation. Such negative publicity could reduce the potential size of the market for our product candidates and decrease the revenues we are able to generate from their sale. To the extent opioid abuse becomes less prevalent or less urgent of a public health issue, regulators and third party payers may not be willing to pay a premium for ADFs of opioids.

Efforts by the FDA and other regulatory bodies to combat abuse of opioids may negatively impact the market for our product candidates. For example, on September 10, 2013, the FDA announced its intention to effect labeling changes to all approved long-acting opioid formulations. In particular, the FDA announced its intention to update the indication for long-acting opioid formulations so that long-acting opioid formulations will be indicated only for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. On April 16, 2014, the FDA updated these indications. It is possible that such changes could reduce the number of prescriptions for opioids written by physicians and negatively impact the potential market for our product candidates.

If the FDA or other applicable regulatory authorities approve generic products with abuse-deterrent claims that compete with any of our product candidates, it could reduce our sales of those product candidates.

Once an NDA, including a Section 505(b)(2) application, is approved, the product covered thereby becomes a "listed drug" which can, in turn, be cited by potential competitors in support of approval of an abbreviated NDA, or ANDA. Potential competitors may create modified, non-infringing versions of a drug to facilitate the approval of an ANDA or other application for generic substitutes. These competitors might only be required to conduct a relatively inexpensive study to show that their product has the same active ingredients, dosage form, strength, route of administration, and conditions of use, or labeling, as our products and that the generic product is absorbed in the body at the same rate and to the same extent as, or is bioequivalent to, our products. These generic equivalents would be significantly less costly than ours to bring to market and companies that produce generic equivalents are generally able to offer their products at lower prices. Thus, after the introduction of a generic competitor, a significant percentage of the sales of any branded product are typically lost to the generic product. Accordingly, competition from generic equivalents to our products would substantially limit our ability to generate revenues and therefore to obtain a return on the investments we have made in our product candidates.

Our relationships with customers and payors will be subject to applicable anti-kickback, fraud and abuse, transparency, and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, exclusion from government healthcare programs, contractual damages, reputational harm, administrative burdens, and diminished profits and future earnings.

Healthcare providers, physicians and payors play a primary role in the recommendation and prescription of any product candidates for which we may obtain marketing approval. Our future arrangements with payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute any product candidates for which we may obtain marketing approval. Even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, federal and state healthcare laws and regulations pertaining to fraud and abuse and patients' rights are and will be applicable to our business. Restrictions under applicable federal, state and foreign healthcare laws and regulations may affect our ability to operate and expose us to areas of risk, including:

23

 

 


 

·

the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under federal and state healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

·

the federal False Claims Act, which imposes criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items and services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;

·

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute to defraud any healthcare benefit program or specific intent to violate it in order to have committed a violation;

·

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and its implementing regulations, which also imposes obligations on certain covered entity healthcare providers, health plans, and healthcare clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

·

federal laws requiring drug manufacturers to report information related to payments and other transfers of value made to physicians and other healthcare providers, as well as ownership or investment interests held by physicians and their immediate family members, including under the federal Open Payments program, commonly known as the Sunshine Act, as well as other state and foreign laws regulating marketing activities; and

·

state and foreign equivalents of each of the above laws, including state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental payors, including private insurers; state laws which require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restricting payments that may be made to healthcare providers; and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Nonetheless, it is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations.

Government agencies may establish and promulgate usage guidelines that could limit the use of our drug candidates.

Government agencies, professional and medical societies, and other groups may establish usage guidelines that apply to our drug candidates. These guidelines could address such matters as usage and dose, among other factors. Application of such guidelines could limit the clinical use or commercial appeal of our drug candidates.

Risks Relating to our Intellectual Property

Our ability to commercialize our drug candidates will depend on our ability to sell such products without infringing the patent or proprietary rights of third parties. If we are sued for infringing the intellectual property rights of third parties, such litigation will be costly and time consuming and an unfavorable outcome would have a significant adverse effect on our business.

Our ability to commercialize our drug candidates will depend on our ability to sell such products without infringing the patents or other proprietary rights of third parties. Intellectual property rights in the areas of controlled-release technology and pharmaceutical ingredients are complicated and are continuously evolving. Holders of patent rights in these areas may allege that the commercialization of REMOXY or our other drug candidates infringes such patent rights. While we believe that we would have valid defenses to any claim of infringement, there can be no assurance that these or other third-party patents will not limit our ability to commercialize REMOXY or our other drug candidates.

In addition, because patent applications are published some time after filing, and because applications can take several years to issue, there may be currently pending third-party patent applications that are unknown to us, which may later result in issued patents. If a third-party claims that we infringe on its patents or other proprietary rights, we could face a number of issues that could seriously harm our competitive position, including:

·

infringement claims that, with or without merit, can be costly and time consuming to litigate, can delay the regulatory approval process and can divert management’s attention from our core business strategy;

·

substantial damages for past infringement which we may have to pay if a court determines that our products or technologies infringe upon a competitor’s patent or other proprietary rights;

·

a court order prohibiting us from commercializing our products or technologies unless the holder licenses the patent or other proprietary rights to us, which such holder is not required to do;

·

if a license is available from a holder, we may have to pay substantial royalties or grant cross licenses to our patents or other proprietary rights; and

·

redesigning our process so that it does not infringe the third-party intellectual property rights, which may not be possible, or which may require substantial time and expense including delays in bringing our own products to market. Such actions could harm our competitive position and our ability to generate revenue and could result in increased costs.

If we are unable to protect our intellectual property, our competitors could develop and market products with similar features that may reduce demand for our drug candidates.

Our success, competitive position and potential future revenues will depend in part on our ability to protect our intellectual property. If we or our collaborators fail to file, prosecute, obtain or maintain certain patents, our competitors could market products that contain features and clinical benefits similar to those of our products, and demand for our products could decline as a result.

We and our collaborators have filed patent applications in the United States and select international jurisdictions to protect our intellectual property. The coverage sought in a patent application can be denied or significantly reduced before or after the patent is issued. Consequently, we do not know whether any of our pending applications will result in the issuance of patents, or if any existing or future patents will provide significant protection or commercial advantage or will be circumvented by others. There can be no assurance that patents will issue from our pending or future patent applications or, if issued, that such patents will be of commercial benefit to us, afford us adequate protection from competing products, or not be challenged or declared invalid. Thus, if these patent applications do not result in issued patents or result in a patent that is challenged by others, the duration or scope of our patent rights may be limited and our future revenues could be lower as a result.

 

We may be involved in challenges to our intellectual property. If our competitors are able to successfully challenge the validity or scope of our patent rights, based on the existence of prior art or otherwise, they might be able to market products that contain features and clinical benefits similar to those of our drug candidates, and demand for our drug candidates could decline as a result. An adverse outcome of a challenge to our intellectual property could result in loss of claims of patents or other intellectual property rights that pertain to certain drugs we currently have under development and could have a material adverse impact on our future revenues.

25

 

 


 

We intend to file additional patent applications relating to our technology, products and processes. We may direct our collaborators to file additional patent applications relating to the licensed technology or we may do so ourselves. However, our competitors may challenge, invalidate or circumvent any of our current or future patents. These patents may also fail to provide us with meaningful competitive advantages.

We may become involved in expensive litigation or other legal proceedings related to our existing intellectual property rights, including patents.

We expect that we will rely upon patents, trade secrets, know-how, continuing technological innovations and licensing opportunities to develop and maintain our competitive position. While we use confidentiality agreements with our employees, consultants and certain of our contractors, if trade secrets or other confidential information is made public, our business may be harmed and our legal remedies may be limited or insufficient. Others may independently develop substantially equivalent proprietary information or be issued patents that may prevent the sale of our products or know-how or require us to license such information and pay significant fees or royalties in order to produce our products.

Our technology could infringe upon claims of patents owned by others. If we were found to be infringing on a patent held by another, we might have to seek a license to use the patented technology. In that case, we might not be able to obtain such a license on terms acceptable to us, or at all. If a legal action were to be brought against us or our licensors, we could incur substantial defense costs, and any such action might not be resolved in our favor. If such a dispute were to be resolved against us, we could have to pay the other party large sums of money and our use of our technology and the testing, manufacture, marketing or sale of one or more of our proposed products could be restricted or prohibited.

If we are unable to protect the confidentiality of our intellectual property, the value of our intellectual property could be materially adversely affected and our business would be harmed.

We seek to protect our intellectual property, in part, by confidentiality agreements with our employees, consultants, scientific advisors, contractors and collaborators. However, there can be no assurance that our intellectual property will not be disclosed or that competitors will not otherwise gain access to our intellectual property or independently develop substantially equivalent intellectual property. For example, if our confidential information were disclosed in violation of our confidentiality agreements, we may not be able to obtain adequate remedies for such breaches. We also seek to protect our intellectual property by maintaining physical security of our premises and physical and electronic security of our information technology systems, but it is possible that these security measures could be breached. If any of our intellectual property were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent such competitor from using that intellectual property to compete with us, which could harm our business.

 

 

Risks Relating to our Business and Strategy

If we are not successful in attracting and retaining qualified personnel, we could experience delays in completing necessary clinical trials, in the regulatory approval process or in formulating, manufacturing, marketing and selling our potential products.

We depend on the services of our key personnel, including Remi Barbier, our Chairman, President and Chief Executive Officer. The loss of key personnel, including members of executive management as well as key bioengineering, product development, and technical personnel, could disrupt our operations and have an adverse effect on our business. We will need to hire additional qualified personnel with expertise in clinical research, preclinical testing, government regulation, formulation and manufacturing and sales and marketing. We compete for qualified individuals with numerous biopharmaceutical companies, universities and other research institutions. Competition for such individuals is intense, and our search for such personnel may not be successful. Attracting and retaining qualified personnel is critical to our success.

We have employees whose equity ownership in the Company could result in a substantial increase in personal wealth if the fair value of our common stock increases. Over time, this increase in personal wealth may make it more challenging to retain these employees.

If third-party manufacturers of our drug candidates fail to devote sufficient time and resources to our concerns, or if their performance is substandard, our clinical trials and product introductions may be delayed and our costs may be higher than expected.

26

 

 


 

We have no manufacturing facilities and have limited experience in drug product development and commercial manufacturing. We lack the resources and expertise to formulate, manufacture or test the technical performance of our drug candidates. We rely on and expect to continue to rely on a limited number of experienced personnel and a small number of contract manufacturers and other vendors to formulate, test, supply, store and distribute drug supplies for our preclinical studies and clinical trials. Our reliance on a limited number of vendors exposes us to the following risks, any of which could delay our clinical trials, and, consequently, FDA approval of our drug candidates and commercialization of our products, result in higher costs, or deprive us of potential product revenues:

·

Contract commercial manufacturers, their sub-contractors or other third parties we rely on and expect to rely on, may encounter difficulties in achieving the volume of production needed to satisfy preclinical and clinical needs or commercial demand, may experience technical issues that impact quality or compliance with applicable and strictly enforced regulations governing the manufacture of pharmaceutical products, and may experience shortages of qualified personnel to adequately staff production operations.

·

Our contract manufacturers could default on their agreements with us to provide supplies or meet our requirements for commercialization of our products.

·

For certain of our drug candidates, the use of alternate manufacturers may be difficult because the number of potential manufacturers that have the necessary governmental licenses to produce narcotic products is limited. Additionally, the FDA and the DEA must approve any alternative manufacturer of our products before we may use the alternative manufacturer to produce our supplies.

·

It may be difficult or impossible for us to find a replacement manufacturer on acceptable terms quickly, or at all. Our contract manufacturers and vendors may not perform as agreed or may not remain in the contract manufacturing business for the time required to successfully produce, store and distribute our products.

·

If any contract manufacturer makes improvements in the manufacturing process for our products, we may not own, or may have to share, the intellectual property rights to such innovation.

We may not be able to successfully develop or commercialize potential drug candidates for indications other than pain.

Our research and development activities include development of potential drug candidates for indications other than pain. We have no history of developing such drug candidates. We do not know whether any of our planned development activities will result in marketable products. We do not anticipate that our drug candidates in these areas will reach the market for at least several years, if at all.

Our employees and consultants are generally subject to confidentiality or other agreements with their former employers and they may inadvertently or otherwise violate those agreements.

Many of our employees and consultants were previously employed at universities or biotechnology or pharmaceutical companies. While we require our employees and consultants to honor any agreements they may have entered into prior to working with us, we may be subject to claims that we inadvertently or otherwise used or disclosed trade secrets or other confidential information belonging to former employers. Failure to defend such claims could result in loss of valuable rights or personnel, which in turn could harm or prevent commercialization of our drug candidates. Successful defense against such claims can be expensive and might distract us from executing our strategies.

Law enforcement concerns over diversion of opioids and social issues around abuse of opioids may make the regulatory approval process and commercialization of our drug candidates very difficult.

Law enforcement agencies or regulatory agencies may apply policies that seek to limit the availability of opioids. Such efforts may adversely affect the regulatory approval and commercialization of our drug candidates.

Developments by competitors may render our products or technologies obsolete or non-competitive.

Alternative technologies and products are being developed to improve or replace the use of opioids for pain management, several of which are in clinical trials or are awaiting approval from the FDA. In addition, the active ingredients in nearly all opioid drugs are available in generic form. Drug companies that sell generic opioid drugs represent substantial competition. Many of these organizations competing with us have substantially greater capital resources, larger research and development staffs and facilities, greater experience in drug development and in obtaining regulatory approvals and greater manufacturing and marketing capabilities than we do. Our competitors may market less expensive or more effective drugs that would compete with our drug candidates or reach market with competing drugs before we are able to reach market with our drug candidates.

27

 

 


 

These organizations also compete with us to attract qualified personnel and partners for acquisitions, joint ventures or other collaborations.

Business interruptions could limit our ability to operate our business.

Our operations, as well as those of our collaborators on which we depend, are vulnerable to damage or interruption from computer viruses, human error, natural disasters, electrical and telecommunication failures, international acts of terror and similar events. We have not established a formal disaster recovery plan and our back-up operations and our business interruption insurance may not be adequate to compensate us for losses we may suffer. A significant business interruption could result in losses or damages incurred by us and require us to cease or curtail our operations.

Unfavorable media coverage of opioid pharmaceuticals could negatively affect our business.

Opioid drug abuse receives a high degree of media coverage. Unfavorable publicity regarding, for example, the use or misuse of oxycodone or other opioid drugs, the limitations of ADFs, public inquiries and investigations into prescription drug abuse, litigation or regulatory activity could adversely affect our reputation. Such negative publicity could have an adverse effect on the potential size of the market for our drug candidates and decrease revenues and royalties, which would adversely affect our business and financial results.

 

 

Risks Relating to Manufacturing

We do not own any manufacturing facilities and we rely on third-party commercial drug manufacturers for drug supply.

 

We do not own any manufacturing facilities. We plan to continue to outsource formulation, manufacturing and related activities.

 

We rely on a limited number of third-party suppliers to formulate, manufacture, fill, label, ship or store all of our drug candidates. These suppliers must comply with current good manufacturing practices, or GMP, enforced by the FDA and other government agencies and U.S. Drug Enforcement Agency, or DEA, regulations and are subject to ongoing periodic unannounced inspection, including preapproval inspections by the FDA and DEA and corresponding state and foreign government agencies to ensure strict compliance with GMP and other government regulations and corresponding foreign standards. These manufacturers may subsequently be stopped from producing, storing, shipping or testing our drug products due to their non-compliance with federal, state or local regulations. We do not have control over our suppliers’ compliance with these regulations and standards.

 

If REMOXY is approved, our commercial suppliers may encounter difficulties in achieving high volumes of production to satisfy commercial demands.

 

We cannot control decisions by our suppliers that affect their ability or willingness to continue to supply us on acceptable terms, or at all.

 

We may not be able to replace a commercial supplier on commercially reasonable terms, or at all. Replacing any of our commercial suppliers would be expensive and time consuming.

 

Failure by any of our suppliers to perform as expected could delay or prevent commercialization of REMOXY or result in shortages, cost overruns, or other problems and would materially harm our business.

 

We will rely on Durect as the sole source of certain excipients in REMOXY. Durect has limited experience manufacturing pharmaceutical products and maintaining GMP-compliant operations. We currently do not have a long-term commercial supply agreement in place with Durect. We expect that we and Durect will negotiate a supply agreement for these excipients. We may not be able to establish a commercial supply agreement on acceptable terms, or at all.

 

If we receive marketing approval for and commercially launch REMOXY, Durect may need to materially expand its manufacturing capacity. Durect may not be able to increase its manufacturing capacity for REMOXY in a timely or economic manner, or at all. Moreover, significant scale up of manufacturing will require additional validation studies, which are subject

28

 

 


 

to FDA review and approval. If Durect is unable to successfully increase the manufacturing capacity, at an acceptable cost or otherwise, and we are unable to establish alternative manufacturing capabilities, there may be a shortage in supply, which would harm our future revenues and cause our business to suffer.

 

If Durect fails to supply excipients to us, they may be in breach of their supply obligations. With or without a commercial supply agreement, Durect’s failure for any reason to supply these excipients, including failure resulting from Durect relying on sole source providers, could delay or prevent commercialization of REMOXY or result in shortages, delays, unexpected costs or other problems and would materially harm our business.

 

We expect to rely on Noramco, Inc., as the sole source of the oxycodone in REMOXY. We currently do not have a long-term commercial supply agreement in place with Noramco. We expect to negotiate with Noramco a commercial supply agreement to supply us with oxycodone. We may not be able to establish a commercial supply agreement on acceptable terms, or at all. Until we have a commercial supply agreement in place with Noramco, we expect to obtain oxycodone from Noramco via purchase orders. There can be no assurance that Noramco will accept our purchase orders on acceptable terms, or at all. With or without a commercial supply agreement, Noramco’s failure for any reason to supply us with oxycodone could delay or prevent commercialization of REMOXY or result in shortages, cost overruns or other problems that would materially harm our business.

 

We expect to rely on Mallinckrodt as the sole-source drug product manufacturer of REMOXY pursuant to an Amended and Restated Commercial Supply Agreement, or the Mallinckrodt Agreement. Pfizer and Mallinckrodt established the Mallinckrodt Agreement when Pfizer was responsible for commercialization of REMOXY. Pfizer assigned the Mallinckrodt Agreement to us in connection with the termination of the Pfizer Agreements. In addition to drug product manufacturing, Mallinckrodt is responsible for sourcing excipients in REMOXY other than those provided by the Durect Agreement. We plan to have Mallinckrodt manufacture pre-validation and commercial validation batches of REMOXY in 2016. Mallinckrodt’s failure for any reason to manufacture and supply REMOXY could delay or prevent commercialization of REMOXY or result in shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that would materially harm our business.

If we cannot formulate and scale-up additional dosage forms of REMOXY, the commercial opportunity for REMOXY might be diminished.

We plan to formulate and scale-up additional dosage forms of REMOXY. We may not be able to successfully complete our formulation or scale-up activities or we may determine that the commercial opportunity for REMOXY in certain dosage forms is too limited to warrant further investment. If we are unsuccessful in our formulation or scale-up activities with REMOXY, our future revenue may be less than expected and our operations may suffer.

We rely solely on Durect to provide us with certain components of drug candidates and will continue to rely on Durect as the sole-source provider of these components.

We rely on Durect as the sole-source provider of certain components of REMOXY and other drug candidates designed to reduce the potential risks of unintended use, and will rely solely on Durect to produce commercial supplies of these components. Durect’s failure for any reason to provide these components or to achieve and maintain satisfactory manufacturing standards could result in product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could materially harm our business.

Durect may encounter manufacturing difficulties involving production yields, quality control and quality assurance. Durect is subject to ongoing periodic unannounced inspection by the FDA and corresponding state and foreign agencies to ensure strict compliance with government regulations and corresponding foreign standards. We cannot control Durect’s compliance with these regulations and standards.

If we receive marketing approval for and commercially launch REMOXY, Durect may need to materially expand its manufacturing capacity. Durect may not be able to increase its manufacturing capacity for REMOXY in a timely or economic manner, or at all. Moreover, significant scale up of manufacturing will require additional validation studies, which are subject to FDA review and approval. If Durect is unable to successfully increase the manufacturing capacity for such components of REMOXY, at an acceptable cost or otherwise, and we are unable to establish alternative manufacturing capabilities, commercialization of REMOXY may be delayed, prevented or impaired or there may be a shortage in supply, which would harm our future revenues and cause our business to suffer.

We expect to rely on Noramco as the sole source of the oxycodone in REMOXY. 

We expect to rely on Noramco as the sole source of the oxycodone in REMOXY. We expect we and Noramco will negotiate a supply agreement to supply us with the oxycodone in REMOXY. Noramco’s operation is subject to regulation by the Drug Enforcement Agency, or DEA and the Controlled Substances Act. Noramco’s failure for any reason to manufacture and supply us with the oxycodone in REMOXY could result in shortages, cost overruns or other problems that could materially harm our business.

We expect to rely on Mallinckrodt as the sole-source drug product manufacturer of REMOXY.

We expect to rely on Mallinckrodt as the sole-source drug product manufacturer of REMOXY pursuant to the Mallinckrodt Supply Agreement. Pfizer and Mallinckrodt established the Mallinckrodt Supply Agreement when Pfizer was responsible for commercialization of REMOXY. Pfizer assigned the Mallinckrodt Supply Agreement to us in connection with the termination of the Pfizer Agreements. Mallinckrodt’s operation is subject to regulation by the DEA and the Controlled Substances Act. In addition to drug product manufacturing, Mallinckrodt is responsible for providing excipients in REMOXY other than those provided by the Durect Agreement. Mallinckrodt’s failure for any reason to manufacture and supply REMOXY could result in shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could materially harm our business.

 

 

Risks Relating to our Financial Position and Need for Financing

Our operating history may make it difficult for you to evaluate our business to date and to assess its future viability.

Our operations from our inception to date have been limited to organizing and staffing our company, acquiring, developing and securing our technology, undertaking preclinical studies and clinical trials of our drug candidates and forming collaborations. We have not yet demonstrated our ability to obtain regulatory approval, formulate and manufacture our drug candidates on a commercial scale or conduct sales and marketing activities. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.

We have a history of losses and expect to incur substantial losses and negative operating cash flows for the foreseeable future.

Although we were profitable in some years in the past based on payments received pursuant to the Pfizer Agreements and interest income, we have yet to generate any revenues from product sales. We have an accumulated deficit of $130.6 million at December 31, 2015. Even if we succeed in developing and commercializing one or more of our drug candidates, we expect to continue to use significant cash resources in our operations for the foreseeable future. We anticipate that our expenses will increase substantially in the foreseeable future as we:

·

continue to conduct preclinical studies and clinical trials for our drug candidates, including drug development activities related to FENROCK;

·

seek regulatory approvals for our drug candidates;

·

develop, formulate, manufacture and commercialize our drug candidates;

·

implement additional internal systems and develop new infrastructure;

·

acquire or in-license additional products or technologies, or expand the use of our technology;

·

maintain, defend and expand the scope of our intellectual property; and

·

hire additional personnel.

We will need to generate significant revenues to achieve and maintain profitability. If we or our collaborators cannot successfully develop, obtain regulatory approval for and commercialize our drug candidates, we will not be able to generate such revenues or achieve profitability in the future. Our failure to achieve or maintain profitability would have a material adverse impact on the market price of our common stock.

If we cannot raise additional capital on acceptable terms, we may be unable to complete planned clinical trials of any or some of our drug candidates or to pursue attractive business opportunities.

30

 

 


 

We have funded all of our operations and capital expenditures with the proceeds from our public and private stock offerings, payments received under the Pfizer Agreements and interest earned on our investments. We expect that our current cash, cash equivalents and marketable securities will be sufficient to meet our working capital and capital expenditure needs for at least the next twelve months. However, we may elect to raise additional funds within such twelve-month period or need to raise additional funds thereafter and additional financing may not be available on favorable terms, if at all. Even if we succeed in selling additional securities to raise funds, our existing stockholders’ ownership percentage would be reduced and new investors may demand rights, preferences or privileges senior to those of existing stockholders. If we raise additional capital through debt financing, if available, such financings may involve covenants that restrict our business activities. If we raise additional capital through strategic alliance and license arrangements, we may have to trade our rights to our technology, intellectual property or drug candidates to others in such arrangements on terms that may not be favorable to us.

If we determine that we need to raise additional funds and we are not successful in doing so, we may be unable to complete the clinical development of some or all of our drug candidates or to seek or obtain FDA approval of our drug candidates. We then could be forced to discontinue product development, enter into a relationship with an additional strategic partner earlier than currently intended, reduce sales and marketing efforts or forego attractive business opportunities.

 

 

Risks Relating to an Investment in our Common Stock

Our stock price has been volatile and could experience a sudden decline in value.

Our common stock has experienced significant price and volume fluctuations and may continue to experience volatility in the future. You may not be able to sell your shares quickly or at the latest market price if trading in our stock is not active or the volume is low. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock:

·

results of or delays in efforts to seek regulatory approval for REMOXY, and in preclinical studies and clinical trials for our other drug candidates;

·

publicity regarding products under development by us or others, including with respect to actual or potential medical results relating to such matters;

·

announcements of technological innovations or new commercial products by us or others;

·

developments in patent or other proprietary rights by us or others;

·

comments or opinions by securities analysts or major stockholders;

·

adverse media coverage related to opioid pharmaceuticals;

·

future sales of our common stock by existing stockholders;

·

developments with respect to potential merger and acquisition activity of companies with whom we have strategic alliances or other agreements;

·

regulatory developments or changes in regulatory guidance enacted by applicable governmental or other authorities;

·

litigation, including with respect to the lawsuit currently filed against us and our officers, or threats of litigation;

·

economic and other external factors or other disaster or crises;

·

the departure of any of our officers, directors or key employees;

·

period-to-period fluctuations in financial results; and

·

limited daily trading volume.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, the Dodd-Frank Act of 2010, SEC regulations and the rules of The NASDAQ Stock Market LLC, create uncertainty for public companies. If we were unable to continue to comply with these requirements, we could be delisted from trading on the NASDAQ Global Select Market, or Nasdaq, and thereafter trading in our common stock, if any, may be conducted through the over-the-counter or other market. As a consequence of such delisting, an investor would likely find it more difficult to dispose of, or to obtain quotations as to the price of, our common stock. Delisting of our common stock could also result in lower prices per share of our common stock than would otherwise prevail.

31

 

 


 

We are involved in a class action filed against us and our officers that is expensive and time consuming, and, in the event of an adverse outcome, such class action could harm our business, financial condition or results of operations.

 

On December 2, 2011, a purported class action was filed against us and our executive officers in the U.S. District Court for the Western District of Texas. This complaint alleges, among other things, violations of Section 10(b), Rule 10b-5, and Section 20(a) of the Exchange Act arising out of allegedly untrue or misleading statements of material facts made by us regarding REMOXY’s development and regulatory status during the purported class period, February 3, 2011 through June 23, 2011. The complaint states that monetary damages are being sought, but no amounts are specified. On June 3, 2013, the Court certified a class consisting of all purchasers of our common stock and a class period of December 27, 2010 through June 26, 2011. In a July 7, 2015 order, the Court directed plaintiffs to file an amended complaint and set a new trial date, if necessary, for March 2017. Plaintiffs filed their amended complaint on July 27, 2015.

As with any litigation proceeding, we cannot predict with certainty the eventual outcome of any outstanding legal actions. We have incurred expenses in connection with the defense of this lawsuit, and we may have to pay damages or settlement costs in connection with any resolution thereof. Any such expenses, damages or settlement costs may be substantial. In addition, because of the number of shareholders involved, plaintiffs in class action lawsuits may claim enormous monetary damages even if the alleged claim is small on a per-shareholder basis. Any such expenses, damages or settlement costs may be substantial. Although we have insurance coverage against which we may claim recovery against some of these expenses and costs, the amount of coverage may not be adequate to cover the full amount or certain expenses and costs may be outside the scope of the policies we maintain. In the event of an adverse outcome or outcomes, our business could be materially harmed from depletion of cash resources, negative impact on our reputation, or restrictions or changes to our governance or other processes that may result from any final disposition of the lawsuit. Moreover, responding to and defending pending litigation significantly diverts management’s attention from our operations.

Anti-takeover provisions in our charter documents and Delaware law may prevent or delay removal of incumbent management or a change of control.

Anti-takeover provisions of our amended and restated certificate of incorporation and amended and restated bylaws and Delaware law may have the effect of deterring or delaying attempts by our stockholders to remove or replace management, engage in proxy contests and effect changes in control. The provisions of our charter documents include:

·

a classified board so that only one of the three classes of directors on our board of directors is elected each year;

·

elimination of cumulative voting in the election of directors;

·

procedures for advance notification of stockholder nominations and proposals;

·

the ability of our board of directors to amend our bylaws without stockholder approval; and

·

the ability of our board of directors to issue up to 10,000,000 shares of preferred stock without stockholder approval upon the terms and conditions and with the rights, privileges and preferences as our board of directors may determine.

In addition, as a Delaware corporation, we are subject to Delaware law, including Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless certain specific requirements are met as set forth in Section 203.

These provisions, alone or together, could have the effect of deterring or delaying changes in incumbent management, proxy contests or changes in control.

Our share ownership is concentrated, and our officers, directors and principal stockholders can exert significant control over matters requiring stockholder approval.

Due to their combined stock holdings, our officers, directors and principal stockholders (stockholders holding greater than 5% of our common stock) acting collectively may have the ability to exercise significant influence over matters requiring stockholder approval including the election of directors and approval of significant corporate transactions. In particular, Remi Barbier, our founder, Chairman of the Board of Directors, President and Chief Executive Officer, owns or controls a significant amount of the voting power of our outstanding capital stock. This concentration of ownership may delay or prevent a change in control of the Company and may make some transactions, including but not limited to any merger, consolidation, or sale of substantially all of our assets, more difficult or impossible to complete without the support of key stockholders.

32

 

 


 

Publicly available information regarding stockholders’ ownership may not be comprehensive because the SEC does not require certain large stockholders to publicly disclose their stock ownership positions.

If the fair value of our stock increases and outstanding Performance Awards vest, we expect to use substantial amounts of cash to fund employee tax liabilities.

We have granted share-based awards that vest upon achievement of certain performance criteria, or Performance Awards. If these Performance Awards vest, we expect to issue our employees shares of our common stock net of statutory employment taxes. This net issuance results in fewer shares issued and uses our cash to fund these taxes. The use of cash could be substantially higher, depending on the fair value of our common stock on the date the Performance Awards vest. If our use of cash to fund these taxes is substantial, our cash balance could substantially decline and our stock price could also decline.

We may in the future seek to fund the cash used for Performance Awards through the sale of our common stock. However, we may not be successful in selling shares of our common stock to fund the cash used for Performance Awards. If the number of shares we sell to fund the cash used for Performance awards is significant, our stock price could decline.

Volatility in the stock prices of other companies may contribute to volatility in our stock price.

The stock market in general, Nasdaq and the market for technology companies in particular, have experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Further, there has been particular volatility in the market prices of securities of early stage life sciences companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. A securities class action suit against us could result in substantial costs, potential liabilities and the diversion of management’s attention and resources.

Our operating results may fluctuate from quarter to quarter and this fluctuation may cause our stock price to decline.

Our quarterly operating results have fluctuated in the past and are likely to fluctuate in the future. Factors contributing to these fluctuations include, among other items, the timing and enrollment rates of clinical trials for our drug candidates, our need for clinical supplies and the valuation of stock-based compensation. Thus, quarter-to-quarter comparisons of our operating results may not be not indicative of what we might expect in the future. As a result, in some future quarters our clinical, financial or operating results may not meet the expectations of securities analysts and investors and could result in a decline in the price of our stock.

If securities or industry analysts publish inaccurate or unfavorable research about our business or product candidates, our stock price could decline.

Securities or industry analysts publish research and reports about our business or product candidates. An analyst’s conclusions regarding prospects for product candidates in the biopharmaceutical industry can include judgments based on the limited publicly-available data. If one or more analysts issues unfavorable research about our business or our product candidates, including a downgrade of our common stock, the price of our stock may decline.

Our stockholders will experience substantial additional dilution if we sell common stock under our at-the-market equity offering.

As of December 31, 2015, there were 10.0 million shares outstanding under our Capital on Demand Sales Agreement™ with JonesTrading Institutional Services LLC, or the JonesTrading Agreement. The sale of additional shares of common stock under the Jones Trading Agreement would be dilutive to the outstanding shares of common stock. Dilution or potential dilution may contribute to our stockholders selling their shares, which would contribute to a downward movement in the stock price of our common stock.

There may not be an active, liquid trading market for our common stock.

There is no guarantee that an active trading market for our common stock will be maintained on Nasdaq. Investors may not be able to sell their shares quickly or at the latest market price if trading in our stock is not active.

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

 

This discussion and analysis should be read in conjunction with our financial statements and accompanying notes included elsewhere in this report. Operating results are not necessarily indicative of results that may occur in future periods.

 

Overview

 

Pain Therapeutics, Inc. develops proprietary drugs that offer significant improvements to patients and healthcare professionals. We generally focus our drug development efforts on disorders of the nervous system, such as chronic pain.

 

Our expertise consists of developing new drug candidates and guiding these through various regulatory and development pathways in preparation for their eventual commercialization. By necessity, the conduct of drug development is complex, lengthy, expensive and risky. The FDA has not yet established the safety or efficacy of our drug candidates.

 

For over a decade, we have pioneered technology, tools and techniques that enable the development of Abuse-Deterrent Formulations, or ADFs. ADFs are intended to make opioid drugs difficult to abuse yet provide steady pain relief when used appropriately by patients. ADFs are intended to help in the fight against prescription drug abuse.

 

Opioid drugs, such as oxycodone, are an important treatment option for patients with severe chronic pain. However, misuse, abuse and diversion of these prescription drugs remains a serious, persistent problem. Nearly 19,000 people died from opioid overdose in 2014, according to the NIH’s National Institute on Drug Abuse.

 

Our lead drug candidate is called REMOXY (oxycodone capsules CII). REMOXY is a proprietary, abuse-deterrent, oral formulation of oxycodone (CII). We developed REMOXY to make oxycodone difficult to abuse yet provide 12 hours of steady pain relief when used appropriately by patients.

In particular, REMOXY’s thick, sticky, high viscosity formulation may deter unapproved routes of drug administration, such as injection, snorting or smoking. REMOXY targets the $2.5 billion marketplace for long-acting formulations of oxycodone. We own exclusive, worldwide rights to REMOXY.

 

In March 2016, we plan to submit to the FDA a New Drug Application, or NDA, for REMOXY. The REMOXY NDA has priority review status with the FDA. We expect a review cycle of about six months. This is a 505(b)(2) NDA resubmission for five dosage strengths of REMOXY (5, 10, 20, 30, 40 mg). The drug’s proposed indication is “for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate”. The safety and clinical efficacy of REMOXY is supported by multiple studies, including a successful Phase III efficacy program conducted under an FDA Special Protocol Assessment. REMOXY’s abuse-deterrence is supported by a body of clinical and non-clinical data, including data comparing REMOXY against currently marketed oxycodone products. The NDA will propose label claims that properly characterize REMOXY’s abuse-deterrent properties, including certain routes of abuse that REMOXY may deter, such as injection, snorting or smoking. The NDA also includes stability data that we believe meet FDA guidance criteria in support of a 24-month shelf life.

 

We have yet to generate any revenues from product sales. We have an accumulated deficit of $130.6 million at December 31, 2015. These losses have resulted principally from costs incurred in connection with research and development activities, salaries and other personnel-related costs and general corporate expenses. Research and development activities include costs of preclinical and clinical trials as well as clinical supplies associated with our drug candidates. Salaries and other personnel-related costs include non-cash stock-based compensation associated with options and other equity awards granted to employees and non-employees. Our operating results may fluctuate substantially from period to period as a result of the timing of preclinical activities, enrollment rates of clinical trials for our drug candidates and our need for clinical supplies.

 

We expect to continue to use significant cash resources in our operations for the next several years. Our cash requirements for operating activities and capital expenditures may increase substantially in the future as we:

 

·

conduct preclinical and clinical trials for our drug candidates;

·

seek regulatory approvals for our drug candidates;

·

develop, formulate, manufacture and commercialize our drug candidates;

·

implement additional internal systems and develop new infrastructure;

37

 

 


 

·

acquire or in-license additional products or technologies, or expand the use of our technology;

·

maintain, defend and expand the scope of our intellectual property; and

·

hire additional personnel.

 

Product revenue will depend on our ability to receive regulatory approvals for, and successfully market, our drug candidates. If our development efforts result in regulatory approval and successful commercialization of our drug candidates, we will generate revenue from direct sales of our drugs and/or, if we license our drugs to future collaborators, from the receipt of license fees and royalties from sales of licensed products. We conduct our research and development programs through a combination of internal and collaborative programs. We rely on arrangements with universities, our collaborators, contract research organizations and clinical research sites for a significant portion of our product development efforts.

 

We focus substantially all our research and development efforts on research and development in the areas of neurology. The following table summarizes expenses by category for research and development efforts (in thousands):

Contractor fees and supplies generally include expenses for preclinical studies and clinical trials and costs for formulation and manufacturing activities. Other common costs include the allocation of common costs such as facilities.

 

Our technology has been applied across certain of our portfolio of drug candidates. Data, know-how, personnel, clinical results, research results and other matters related to the research and development of any one of our drug candidates also relate to, and further the development of, our other drug candidates. As a result, costs allocated to a specific drug candidate may not necessarily reflect the actual costs surrounding research and development of that drug candidate due to cross application of the foregoing.

 

Estimating the dates of completion of clinical development, and the costs to complete development, of our drug candidates would be highly speculative, subjective and potentially misleading. Pharmaceutical products take a significant amount of time to research, develop and commercialize. The clinical trial portion of the development of a new drug alone usually spans several years. We expect to reassess our future research and development plans based on our review of data we receive from our current research and development activities. The cost and pace of our future research and development activities are linked and subject to change. 

 

On December 2, 2011, a purported class action was filed against us and our executive officers in the U.S. District Court for the Western District of Texas. This complaint alleges, among other things, violations of Section 10(b), Rule 10b-5, and Section 20(a) of the Exchange Act arising out of allegedly untrue or misleading statements of material facts made by us regarding REMOXY’s development and regulatory status during the purported class period, February 3, 2011 through June 23, 2011. The complaint states that monetary damages are being sought, but no amounts are specified. On June 3, 2013, the Court certified a class consisting of all purchasers of our common stock and a class period of December 27, 2010 through June 26, 2011. In a July 7, 2015 order, the Court directed plaintiffs to file an amended complaint and set a new trial date, if necessary, for March 2017. Plaintiffs filed their amended complaint on July 27, 2015.

 

 

Critical Accounting Policies

 

The preparation of our financial statements in accordance with United States generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and interest income in our financial statements and accompanying notes. We evaluate our estimates on an ongoing basis, including those estimates related to agreements, research collaborations and investments. We base our estimates on historical experience and 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

38

 

 


 

results may differ from these estimates under different assumptions or conditions. The following items in our financial statements require significant estimates and judgments:

 

·

Stock-based compensation.  We recognize expense for the fair value of all share-based payments to employees and directors, including grants of employee stock options and other share based awards, in the Statements of Operations. For stock options, we use the Black-Scholes option valuation model and the single-option award approach and straight-line attribution method. Using this approach, the compensation cost is amortized on a straight-line basis over the vesting period of each respective stock option, generally four years.

 

We have granted share-based awards that vest upon achievement of certain performance criteria, or Performance Awards. The value of these awards is the product of the number of shares of our common stock to be issued under the award multiplied by the fair market value of a share of our common stock on the date of grant. These awards include future performance conditions. We estimate an implicit service period for achieving these performance conditions. Performance Awards vest and common stock is issued on achieving performance conditions. We recognize stock-based compensation expense for Performance Awards when we conclude that achieving a performance condition is probable. We periodically review and update as appropriate our estimates of the implicit service periods and the likelihood of achieving the performance conditions.

 

·

Revenue recognition.  We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable, and collection is reasonably assured. Program fee revenue in 2013 was derived from upfront payments under the Pfizer Agreements. Through 2013, these payments were recognized from receipt over our estimate of the development period for product candidates under the Pfizer Agreements. In October 2013, we and Pfizer amended the Pfizer Agreements and, as a result of the amendment, we recognized all then-remaining deferred program fee revenue as program fee revenue.

 

·

Income Taxes.  We make estimates and judgments in determining the need for a provision for income taxes, including the estimation of our taxable income or loss for each full fiscal year. We have accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of deferred tax assets is dependent upon future earnings, if any. We are uncertain as to the timing and amount of any future earnings. Accordingly, we offset these deferred tax assets with a valuation allowance. We may in the future determine that our deferred tax assets will likely be realized, in which case we will reduce our valuation allowance in the quarter in which such determination is made. If the valuation allowance is reduced, we may recognize a benefit from income taxes in our statement of operations in that period. We classify interest recognized in connection with our tax positions as interest expense, when appropriate.

 

 

Results of Operations

 

Years Ended December 31, 2015 and 2014

 

Research and Development Expense

 

Research and development expense consists primarily of costs of development work associated with our drug candidates. Research and development expenses increased to $9.1 million in 2015 from $7.3 million in 2014,  primarily due to increased third-party spending on preparing the NDA resubmission for REMOXY. During 2015, we received $0.3 million pursuant to a grant from the National Institutes of Health that we recorded as a reduction to our research and development expenses. Research and development expenses included $1.2 million in non-cash stock related compensation expense in 2015 and $1.6 million in non-cash stock related compensation expense in 2014.  

We expect research and development expense to fluctuate over the next several years as we continue our development efforts. We expect our development efforts to result in our drug candidates progressing through various stages of clinical trials. Our research and development expenses may fluctuate from period to period due to the timing and scope of our development activities and the results of clinical trials and preclinical studies.

 

39

 

 


 

General and Administrative Expense

 

General and administrative expense consists primarily of compensation and other general corporate expenses. General and administrative expense was $5.1 million in both 2015 and 2014. General and administrative expenses included $2.3 million in non-cash stock related compensation expense in 2015 and $2.1 million in non-cash stock related compensation expense in 2014. 

 

We expect other general and administrative expense to increase over the next several years in connection with support of precommercialization and commercialization activities for our drug candidates. The increase may fluctuate from period to period due to the timing and scope of these activities and the results of clinical trials and preclinical studies.

 

Interest Income

 

Interest and other income, net, was  $0.1 million in both 2015 and 2014.  We expect our interest income to decrease in the future as we use cash to fund our operations.

 

Years Ended December 31, 2014 and 2013

 

Revenue – Program fee revenue 

 

We received a $150.0 million upfront fee in 2005 in connection with the closing of the Pfizer Agreements and $5.0 million in July 2010 in connection with an amendment to the Pfizer Agreements.  As a result of the October 2013 amendment to the Pfizer Agreements, we recognized the balance of current and non-current portions of deferred program fee revenue as program fee revenue during the fourth quarter of 2013. Related program fee revenue was $41.1 million in 2013.

 

Research and Development Expense

 

Research and development expense consists primarily of costs of development work associated with our drug candidates. Research and development expenses increased to $7.3 million in 2014 from $4.9 million in 2013,  primarily due to increased third-party spending on our research and development candidates. Research and development expenses included $1.6 million in non-cash stock related compensation expense in 2014 and $1.3 million in non-cash stock related compensation expense in 2013.  

 

General and Administrative Expense

 

General and administrative expense consists primarily of compensation and other general corporate expenses. General and administrative expense increased to $5.1 million in 2014 from $4.8 million in 2013, primarily due to higher cash non-cash stock related compensation and general corporate activities. General and administrative expenses included $2.1 million in non-cash stock related compensation expense in 2014 and $1.8 million in non-cash stock related compensation expense in 2013. 

 

Interest Income

 

Interest and other income, net, was  $0.1 million in both 2014 and 2013.  

 

Provision for Income Taxes

 

In 2013, we recognized a benefit from income taxes related to unrecognized tax benefits for use of certain research and development tax credits in 2006. We did not provide for federal income taxes in 2014 or 2013 because we had a tax loss for both 2014 and 2013.  

 

 

Liquidity and Capital Resources

 

Since inception, we have financed our operations primarily through public and private stock offerings, payments received under the Pfizer Agreements and interest earned on our investments. We intend to continue to use our capital resources to

40

 

 


 

fund research and development activities, capital expenditures, working capital requirements and other general corporate purposes. As of December 31, 2015, cash, cash equivalents and marketable securities were $31.3 million.

 

Net cash used in operating activities decreased to  $9.1 million for 2015 from  $9.5 million for 2014 primarily due to the timing of payments for accounts payable and accrued development expenses in 2015 as compared to 2014, offset in part by higher operating expenses in 2015 as compared to 2014.

 

Net cash used by investing activities was $0.2 million for 2015 compared to cash provided by investing activities of  $1.2 million for 2014. Investing activities for both years consisted primarily of the purchase and maturities of marketable securities.

 

Net cash used by financing activities of $46,000 in 2015 resulted from cash used to establish the JonesTrading Agreement. Cash provided by financing activities of $0.4 million in 2014 resulted from cash from stock option exercises.

 

Realization of our deferred tax assets is dependent on future earnings, if any. We are uncertain about the timing and amount of any future earnings. Accordingly, we offset these net deferred tax assets with a valuation allowance.

We lease approximately 6,000 square feet of office space pursuant to a non-cancelable operating lease in Austin, TX that expires in 2017. Future minimum lease payments by year are as follows (in thousands):

We have license agreements that require us to make milestone payments upon the successful achievement of milestones, including clinical milestones. Our license agreements also require us to pay certain royalties to our licensors if we succeed in fully commercializing products under these license agreements. All of these potential future payments are cancelable as of December 31, 2015. Our formulation agreement with Durect Corporation obligates us to make certain milestone payments upon achieving clinical milestones and regulatory milestones.

 

We have an accumulated deficit of $130.6 million at December 31, 2015. We expect our cash requirements to be significant in the future. The amount and timing of our future cash requirements will depend on regulatory and market acceptance of our drug candidates and the resources we devote to researching and developing, formulating, manufacturing, commercializing and supporting our products. We believe that our current resources should be sufficient to fund our operations for at least the next 12 months. We may seek additional future funding through public or private financing within this timeframe, if such funding is available and on terms acceptable to us.

 

No shares were issued under the JonesTrading Agreement in 2015. As of December 31, 2015, there were 10.0 million shares outstanding under the JonesTrading Agreement. We deferred financing costs of $0.1 million at December 31, 2015 paid in connection with entering into the Jones Trading Agreement

 

Off-balance Sheet Arrangements

 

As of December 31, 2015, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. Therefore, we are not materially exposed to financing, liquidity, market or credit risk that could arise if we had engaged in these relationships. We do not have relationships or transactions with persons or entities that derive benefits from their non-independent relationship with us or our related parties.

 

 

Item 7A.Quantitative and Qualitative Disclosures about Market Risk

 

The primary objective of our cash investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk. 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 principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the interest rate later rises, the principal amount of our investment will probably decline. A hypothetical 50 basis point increase in interest rates reduces the fair value of our available-for-sale securities at December 31, 2015 by $3,756. To minimize this

41

 

 


 

risk in the future, we intend to maintain our portfolio of cash equivalents and marketable securities in a variety of securities, including commercial paper, government and non-government debt securities and/or money market funds that invest in such securities. We have no holdings of derivative financial or commodity instruments. As of December 31, 2015, our investments consisted of investments in commercial paper, corporate notes and obligations or in money market accounts and checking funds with variable market rates of interest. We believe our credit risk is immaterial.
