PART I

ITEM 1.  BUSINESS

Overview

We are a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty pharmaceutical products that leverage our broad experience with advanced transdermal and transmucosal delivery systems. We have multiple proprietary programs in preclinical and clinical development focusing primarily on the treatment of neurological disorders, with two lead programs in Alzheimer’s disease. We have developed and are the sole commercial manufacturer of seven prescription drug and consumer products for our marketing partners. We have two proprietary transdermal platforms: Corplex™ for small molecules and MicroCor®, a biodegradable microstructure technology for small molecules and biologics, including vaccines, peptides and proteins.  Our late-stage pipeline includes a contraceptive patch co-developed with Agile Therapeutics that recently completed Phase 3 trials, and additional transdermal products that are being developed with other partners.

Transdermal drug delivery is the transport of drugs through the skin for absorption into the body. We believe our platforms offer significant competitive advantages over competing transdermal approaches. Corplex and MicroCor are designed to be adapted broadly for use in multiple drug categories and indications. We use our Corplex technology to create advanced transdermal and transmucosal systems for small molecules that:

Our MicroCor technology is a biodegradable microstructure system currently in development that enables the painless and convenient delivery of biologics that otherwise must be delivered via injection.

We have built significant know-how and experience in the development, scale-up and manufacture of complex specialty products, and have formed relationships with our partners that include both the development of new product formulations and our manufacture of the resulting products. Our partners include Teva Pharmaceuticals USA, Inc. (“Teva”), Mayne Pharma Inc. (“Mayne”), Endo Pharmaceuticals, Inc. (formerly Par Pharmaceutical, Inc. (“Par”)) (“Endo”), The Procter & Gamble Company (“P&G”), Agile Therapeutics, Inc. (“Agile”), and Aequus Pharmaceuticals, Inc. (“Aequus”), as well as several other multinational pharmaceutical companies. All of our current commercial products are distributed, promoted and marketed by our partners.

The following table identifies: (1) products we have developed that are marketed by our partners, (2) products we have developed with our partners that are in clinical trials and that our partners have permitted us to disclose, (3) products in our proprietary pipeline, and (4) products currently awaiting FDA approval.

Our partnership with Teva began in 2004, with Teva’s predecessor, Barr Laboratories, Inc. (“Barr”). Together with Barr, we developed a clonidine Transdermal Delivery System (“TDS”), which Teva commercially launched in 2010.  In August 2016, Teva transferred Clonidine TDS and the product-related agreements to Mayne as a result of a Federal Trade Commission (“FTC”) consent order in which Teva agreed to divest the product in connection with Teva’s acquisition of the generic business of Allergan, plc (formerly Actavis, Inc. (“Actavis”)) (“Allergan”). Mayne currently sells Clonidine TDS throughout North America. 

Our partnership with Par, which was acquired by Endo in September 2015, is likewise the result of an FTC-mandated divestiture of Fentanyl TDS from Actavis in connection with the merger of Actavis with Watson Pharmaceuticals, Inc. We began the development of Fentanyl TDS with Abrika LLLP in May 2002, and Abrika was subsequently acquired by Actavis in 2007. Actavis commercially launched Fentanyl TDS in 2007. Endo currently sells Fentanyl TDS throughout the United States. 

Our partnership with P&G began in 2005 with the development of the various products under the Crest® Whitestrips label, the first of which P&G commercially launched in 2009. P&G currently sells Crest Whitestrips products in North America and internationally.

In addition to commercialized products, we have a number of products in late stages of development. One of these products is Twirla, which is a combination hormonal contraceptive patch designed to deliver two hormones, ethinyl estradiol and levonorgestrel, at levels comparable to low-dose oral contraceptives, through the skin over seven days. Agile has recently completed a confirmatory Phase 3 clinical trial, and expects to announce top-line data in early January 2017. We are the exclusive manufacturer of the product for Agile.

We are developing several additional products utilizing our proprietary technologies that we advanced into human clinical trials during 2015 and 2016.  Our two lead central nervous system product candidates are for the transdermal treatment of Alzheimer’s disease and incorporate the two most commonly-prescribed drugs already approved by the FDA for this disease: donepezil and memantine.

Alzheimer's disease is a progressive brain disorder in which the brain cells degenerate and die, causing a steady decline in memory and mental function.  An estimated 5.1 million Americans suffered from Alzheimer's disease in 2015 and, by 2025, this number is estimated to reach 7.1 million.  Alzheimer's disease is the most common cause of dementia among older adults.  Dementia ranges in severity from mild, when it is just beginning to affect a person's functioning, to moderate, and severe, when the person must depend on others for the basic activities of day-to-day life.

Donepezil (the active ingredient in Aricept®) is the most widely-prescribed medication in a class of Alzheimer's drugs known as cholinesterase inhibitors, and is approved for the treatment of mild, moderate and severe disease.  Donepezil is currently only available in tablet or orally disintegrating tablet form, each administered once daily, presenting compliance challenges for family members and caregivers who cannot rely on patients to consistently take their daily tablets, and is known to cause gastrointestinal side effects, including nausea, vomiting and loss of appetite.

Memantine (the active ingredient in Namenda®) is one of the most widely-prescribed medications for the treatment of moderate to severe dementia of the Alzheimer’s type.  Memantine is the only FDA-approved N-methyl-D-aspartate (“NMDA”)-receptor antagonist for use in Alzheimer’s and works by regulating the activity of glutamate, a neurotransmitter in the brain involved in learning and memory.  Memantine is currently only available in once- and twice-daily oral dosage forms. As with donepezil, this presents compliance challenges for family members and caregivers who cannot rely on patients to consistently take their daily oral medications.

Our donepezil and memantine candidates first entered into Phase 1 clinical trials in the fourth fiscal quarter of 2015, and we announced successful results for several donepezil and memantine clinical trials throughout fiscal 2016. In April 2016, we received positive feedback from the FDA on our pre-Investigational New Drug (“pre-IND”) submission that outlined our proposed 505(b)(2) regulatory pathway for Corplex Donepezil based solely on a demonstration of bioequivalence. Bioequivalence clinical studies are designed to assess the biological equivalence of pharmaceutical products based on their pharmacokinetic (“PK”) profiles, and are generally performed in healthy subjects.  These studies are relatively short in duration and provide a development path that is substantially less costly and more streamlined than typical clinical development programs, which require studies demonstrating safety and efficacy. Following review of our pre-IND submission, the FDA provided clear guidance on our development plans and registration pathway. The agency advised us that if we can adequately demonstrate bioequivalence between Corplex Donepezil and oral Aricept in our planned PK bioequivalence studies, additional clinical efficacy studies would not be required. 

Additionally, in August 2016, after review of our pre-IND submission of Corplex Memantine, the FDA concurred with our development plans for this product, including our proposal for pivotal studies based on the demonstration of bioequivalence between the Corplex Memantine and oral Namenda XR® extended release capsules.

Our proprietary pipeline also includes Corplex Ropinirole for the treatment of Parkinson’s disease. Parkinson’s disease is the second most common neurodegenerative disorder after Alzheimer’s disease and many Parkinson’s patients have trouble swallowing pills. Approximately one million people in the United States and from four to six million people worldwide suffer from this disease, which is commonly treated with dopamine replacement therapies such as levodopa and dopamine agonists that mimic the action of dopamine. We have performed the preclinical development work on a transdermal formulation of ropinirole, a proven and FDA-approved dopamine agonist for treating Parkinson’s disease. We anticipate developing this patch under a 505(b)(2) regulatory pathway, which we believe will allow for reduced nonclinical and clinical study cost and time.

MicroCor hPTH(1-34) is our most advanced product candidate utilizing our MicroCor technology.  In July 2015, we reported positive interim top-line results from a Phase 2a trial of this product candidate, which delivers parathyroid hormone, a peptide for treating osteoporosis that is currently available only in an injectable form that requires refrigeration.

In April 2015, we entered into an agreement with Aequus to develop new transdermal products with an initial focus on neurological and psychiatric disorders. The first project under this collaboration is a multi-day transdermal formulation of aripiprazole, a drug already approved by the FDA for the treatment of a variety of psychiatric conditions. Aequus initiated a Phase 1 bioavailability clinical trial for this product in the fourth calendar quarter of 2015, and reported positive results in the first calendar quarter of 2016.

We also have ongoing feasibility agreements with several pharmaceutical and biotechnology companies involving our Corplex and MicroCor technologies, and are currently in active discussions with other parties for additional feasibility and partnering projects.

Transdermal Drug Delivery Industry

Patients have benefited from the use of transdermal delivery systems since the first commercially approved transdermal product, ALZA Corporation’s Transderm Scop for the prevention of motion sickness, was approved in 1979. To date, we are aware of approximately 20 drugs that have been successfully formulated and approved by the FDA for delivery in transdermal patches. According to Transdermal Drug Delivery Market & Clinical Pipeline Insight in a report dated May 2014, the global value of the market for systemic transdermal products, including patches, was approximately $25 billion in 2013 and is expected to grow to approximately $40 billion by 2018. We believe that growth of this market is driven by the increasing availability of transdermal systems for important therapeutic applications and changing disease demographics.

Transdermal delivery and transmucosal delivery, or delivery through mucous membranes, offer patients more convenient, non‑invasive and comfortable methods of drug delivery. The benefits of transdermal and transmucosal delivery systems over other dosage forms generally include enhancing the efficacy and reducing the side effects of a drug by controlling the rate of delivery and absorption, avoiding the undesirable breakdown of drugs in the liver associated with gastrointestinal absorption, and improving the level of patient compliance and long‑term adherence to therapy.

Despite the benefits of current transdermal delivery products, many key challenges prevent broader use and applicability:

One of the greatest opportunities in transdermal drug delivery is the ability to deliver biologics, including vaccines, peptides and proteins, without the use of an injection. A number of companies have attempted to develop technologies to address this challenge, but many have experienced commercial and development failures due to the formulation, scale‑up and manufacturing complexities. Some of these systems have relied upon large, complex and costly devices, usually with external power sources, which adversely impact their usability and reproducibility.

We are developing and commercializing advanced transdermal drug delivery products that are intended to expand the number and types of drugs that can be delivered transdermally. We believe our technologies can be applied to improve the therapeutic value of many drugs by controlling the levels of drug delivered over a longer period of time. They are also designed to eliminate the need for injections of certain drugs and to improve adhesion and skin irritation profiles. Our technologies also allow us to create cost‑effective products, especially by eliminating the need for complex devices and refrigeration throughout the supply chain. Our two proprietary platforms, Corplex and MicroCor, separately address some of the primary shortcomings of traditional transdermal drug delivery. We believe our track record within the industry demonstrates our ability to develop commercially successful products.

Corplex Technology

Corplex is a novel technology incorporating combinations of materials that utilize the properties of both traditional pressure‑sensitive adhesives (“PSAs”), as well as bioadhesives, to enable the transdermal delivery of small molecules. Corplex encompasses combinations and blends of polymers to provide a range of properties that improve adhesion and delivery of active ingredients that may otherwise be difficult to formulate for transdermal delivery. We use our Corplex technology in the Crest Whitestrips products and in several of our therapeutic products in development, including our Corplex Donepezil and Corplex Memantine products. Our Corplex transdermal delivery systems provide advanced custom solutions for small molecules and feature the following benefits:

We believe the combination of these benefits make Corplex well‑suited for the development of a variety of healthcare products that require adhesive properties. Our primary focus is on developing prescription transdermal drug products, with an emphasis on chronic central nervous system diseases such as Alzheimer’s and Parkinson’s, where the goal of therapy is to maintain consistent blood levels of therapeutic agents over months or years and the nature of the disease makes compliance with daily oral medications particularly problematic.

MicroCor Technology

MicroCor is a biodegradable microstructure patch technology that we are developing to enable transdermal delivery of biologics, in a disruptive platform that reduces the need for needles and syringes and enables global

distribution of biologics without requiring refrigeration. Because biologics cannot diffuse through the skin due to their size, some mechanism is required to introduce these molecules beyond the outer layer of the skin, or stratum corneum, where they can be absorbed into the body. The further a delivery system penetrates beyond the stratum corneum, the more likely it is to cause pain, bleeding and bruising. By integrating active ingredients directly into arrays of biodegradable microstructures, our MicroCor technology is designed to penetrate only the stratum corneum to release the drug for local or systemic absorption, while eliminating the pain, bleeding and bruising that can be caused by needles and other active delivery devices.

We believe MicroCor will offer the following advantages over other delivery technologies in development for biologics:

Material Relationships

Our partners are critical to our success. We currently have material relationships with the following companies, as well as earlier‑stage relationships with a number of other companies. This diversified mix of partnerships provides multiple potential sources of revenue growth in the future. In each of fiscal 2016 and 2015, we derived nearly all of our revenues from our partners Teva/Mayne, Endo/Par and P&G. In fiscal 2016, we received $7.4 million of our revenues from Teva/Mayne, $6.6 million from Endo/Par, and $13.9 million from P&G, or 22%, 20%, and 42%, respectively. In fiscal 2015, we received $12.4 million from Teva/Mayne, $9.6 million from Endo/Par and $11.6 million of our revenues from P&G, or 30%, and 23% and 28%, respectively.

Teva Pharmaceuticals, USA Inc./Mayne Pharma, Inc.

In 2004, we entered into a development, manufacturing and commercialization agreement with Barr Laboratories, Inc. for four generic transdermal drug products. We entered into three separate agreements with Barr, one in 2006 and two in 2007, to develop and commercialize additional Abbreviated New Drug Application (“ANDA”)

transdermal patch products. In 2008, Teva acquired Barr. Following this acquisition and its review of resource allocations and potential conflicts, Teva continued three of these development programs. These programs have resulted in an approved product marketed as Clonidine TDS, a urology patch approved in March 2014 and a motion sickness patch that is the subject of a pending ANDA. In August 2016, Teva transferred Clonidine TDS and the agreements related to this product to Mayne as a result of an FTC consent order in which Teva agreed to divest the product in connection with Teva’s acquisition of the generic business of Allergan. Mayne currently sells Clonidine TDS throughout North America.

Under our agreements with Mayne, we are the exclusive supplier of the Clonidine TDS product that we developed. We received compensation for developing the product, and we receive a manufacturing margin, expressed as a margin above costs, and a profit share based on Mayne’s net profits on the products. Mayne has an exclusive license to use certain of our intellectual property to the extent necessary to commercialize, make, use or sell the ANDA products that are the subject of their respective agreements.

The contract for Clonidine and the motion sickness patch extend for ten years beyond the respective product launch dates, with provisions for automatic annual renewal thereafter. Each contract may be terminated, with three months’ notice before the end of a renewal period, or for uncured material breach, bankruptcy, or certain conditions preceding ANDA filing. If any of these agreements were to be terminated, Teva or Mayne, as the case may be, would be required to obtain FDA approval for an alternate manufacturing site before they could obtain additional supply of the relevant product, a process that generally takes two years or more.

In addition to contract research and development revenues and product revenues, from the inception of our collaborations with Teva and its predecessor, we have received no license fees and $0.2 million in milestone payments. We have received no contract research and development revenues, license fees or milestone payments from Mayne. Under our current agreements, we are not eligible for additional milestone payments from either Teva or Mayne. We also receive a profit share equal to a low tens percentage of Teva’s and Mayne’s net sales of Clonidine TDS, after deducting certain selling‑related expenses.

Endo Pharmaceuticals, Inc./Par Pharmaceutical, Inc.

In 2002, we entered into a product development, collaboration and license agreement and in 2003 we entered into a manufacturing and supply agreement with Abrika LLLP for a generic equivalent of Duragesic, a fentanyl transdermal product marketed by Johnson & Johnson. In 2007, Abrika was acquired by Actavis, Inc. In 2007, the FDA approved and Actavis launched our Fentanyl TDS product. In 2012, Par, a wholly-owned subsidiary of Endo since 2015, acquired the fentanyl business from Actavis, and Endo/Par currently markets Fentanyl TDS as our partner. Under the manufacturing and supply agreement, we are the exclusive supplier of Fentanyl TDS to Endo/Par.

Abrika and Actavis paid us for the development of Fentanyl TDS and we also receive a manufacturing margin and have historically been paid a royalty on net sales of the products by Par. The 2002 agreement may be terminated for uncured material breach, bankruptcy, or certain conditions preceding ANDA filing. If Par were to terminate the agreement, it would be required to obtain FDA approval for an alternate manufacturing site before it could obtain additional supply of the product, a process that generally takes two years or more.

On June 26, 2015, we amended our agreements with Par, consisting of the Product Development, Collaboration and License Agreement and the Manufacturing and Supply Agreement for Transdermal Fentanyl, to amend the pricing and payment provisions and other business terms in exchange for, among other things, the termination of Par’s exclusive rights to products other than the fentanyl reservoir patch currently being manufactured by us for Par, which is an AB-rated generic equivalent to DURAGESIC®. The amended terms also included the elimination of the royalty obligations and establish mutually agreeable transfer pricing.

In addition to contract research and development revenues and product revenues, from the inception of our collaborations with Endo/Par and its predecessors, we have received no license fees and $0.5 million in milestone payments from Par. Under our current agreements, we are not eligible for additional milestone payments.

The Procter & Gamble Company

In June 2005, we entered into a multi‑faceted strategic arrangement with P&G, one of the largest consumer products companies in the world. Our relationship includes a worldwide license to P&G for the use of our Corplex technology in products in the oral care field. P&G paid us fees for the license, and agreed to pay additional future milestone payments for products that we develop for P&G. In addition, we entered into a long term joint development agreement under which we perform numerous research and development activities for P&G based upon agreed‑upon statements of work and budgets. We also have a commercial supply agreement in place, under which we are responsible for the production and supply to P&G of five oral care products. Our supply agreement with P&G currently extends through January 2017 and can be expanded to include any additional products that move into commercial supply. We believe that we have unique capabilities and know‑how related to the manufacture of Corplex‑based Crest Whitestrips, which would be difficult for another party to duplicate.

We have developed and commercialized five oral care products for P&G sold under the brand name Crest Whitestrips. We have developed all of these products under the joint development agreement and are currently supplying each product in an intermediate (as opposed to final packaging) stage to P&G.

In addition to contract research and development and product revenues, from the inception of our collaborations with P&G, we have received a total of $3.2 million in license fees and $3.6 million in milestone payments from P&G. In 2008, we received a $2.0 million milestone payment for the first series of products developed by us. In fiscal 2016, we received a $1.1 million milestone payment from P&G for the approval of the U.S. commercial launch of a product developed by us. In 2015, we received a $0.5 million milestone payment for the launch of the same product outside of the United States. P&G's license from us is perpetual and irrevocable. None of our arrangements with P&G require a royalty to be paid to us.

Agile Therapeutics, Inc.

In 2006, we entered into a development, license and commercialization agreement with Agile, a company that focuses on development of women’s healthcare products. As part of our relationship, we are the exclusive supplier of Twirla, a combined hormonal contraceptive patch, which was designed by Agile using its formulation technology and is proprietary to Agile. Under our agreement with Agile, we have performed substantial work, funded by Agile, on the process development and scale‑up of the manufacturing process for Twirla, and we have manufactured the product for each of Agile’s clinical trials. We are also working with Agile under this agreement on development of a “small patch” variation on the Twirla product. Our agreement also includes an additional Agile product, AG890, which is a progestin‑only contraceptive patch in Phase 2 of clinical development.

We have worked in partnership with Agile to prepare facilities and equipment at our Grand Rapids manufacturing site for commercial production of the product. The primary production equipment specifically designed for manufacture of this product is in place and is owned by Agile, and we are responsible for operating and maintaining that equipment.

Our exclusive right to manufacture Twirla and AG890 extends until we have commercially produced an agreed‑upon quantity of patches, currently projected to occur no earlier than five years following commercial launch of Twirla. The contract may be terminated for uncured material breach. Following the end of the exclusivity period, if Agile were to seek a second source of supply, Agile would be required to obtain FDA approval for an additional manufacturing site, a process that generally takes two years or more, and make substantial investments in new facilities and equipment.

In addition to contract research and development revenues, from the inception of our collaborations with Agile, we have received no license fees and $3.5 million in milestone payments from Agile. We are not currently eligible for any future milestone payments, and the terms of our supply agreement do not entitle us to receive a royalty.

Products and Pipeline

We have seven commercial products and two products awaiting FDA approval, and we are developing additional undisclosed prescription drug products with partners. We also have ongoing feasibility agreements with several pharmaceutical and biotechnology companies involving our Corplex and MicroCor technologies, and are currently in active discussions with other parties for additional feasibility and partnering projects.

Marketed Products:

In fiscal 2016, we received a total of $25.4 million in product revenues from our three marketed products: $6.8 million from Clonidine TDS, $6.4 million from Fentanyl TDS, and $12.2 million from Crest Whitestrips, representing 27%, 25% and 48% of total product revenues, respectively.

Clonidine TDS is a treatment for hypertension that we developed under an ANDA as a generic version of the branded drug known as Catapres-TTS®. Clonidine TDS was launched in 2010 by Teva and is now marketed by Mayne, following an FTC-mandated divestiture, and is manufactured by us exclusively for Mayne.

Fentanyl TDS is a treatment for management of chronic pain, including cancer‑related pain, under specified conditions. We developed this product for approval under an ANDA as a generic version of the branded product known as Duragesic. Our Fentanyl TDS was approved in 2007 and is currently marketed by Endo/Par and manufactured by us exclusively for Endo/Par.

Crest Whitestrips are a series of five products for oral care that we co‑developed with P&G as part of a broad relationship relating to oral care products. These products utilize our Corplex polymer technology and are sold under the Crest Whitestrips brand. We are the sole supplier of the oral care system for P&G.

Pipeline Products:

Twirla is a combination hormonal contraceptive patch that contains the active ingredients ethinyl estradiol (an estrogen) and levonorgestrel (a progestin), both of which have an established history of efficacy and safety in currently marketed combination contraceptives. Twirla is designed to deliver both hormones at levels comparable to low‑dose oral contraceptives. By delivering these active ingredients over seven days, this product is designed to promote enhanced compliance by patients with a convenient, easy‑to‑use format. The patch is applied once weekly for three weeks, followed by a week without a patch. The product, which was designed by Agile and for which we have done process development and manufacturing, will, if approved, be packaged with three patches per carton to provide a cycle (month) of therapy.

In February 2013, Agile received a Complete Response Letter from the FDA, indicating that the results from the completed Phase 3 studies would not be sufficient for approval, and proposing that Agile conduct an additional Phase 3 study. In September of 2014, Agile initiated the additional study as requested by FDA, which it recently completed and anticipates announcing top-line data in early January 2017. This study has been designed to address key issues that arose in the previous studies, including enhanced patient enrollment criteria and processes, and close monitoring of compliance with the study protocol. There can be no assurance that this additional study will be successful in demonstrating efficacy and safety of the product. However, assuming successful completion of this additional study, Agile has indicated that it plans to submit the results of the confirmatory study to the FDA in the first half of calendar 2017. Assuming a six‑month review by the FDA, approval could occur late in calendar 2017. We are also working with Agile under our agreement on development of a “small patch” variation on the Twirla product.

Corplex Donepezil and Corplex Memantine are being developed as once-weekly transdermal patches for the treatment of Alzheimer’s disease and are designed to provide consistent and sustained blood levels of the relevant therapeutic agent, while improving patient adherence and compliance.  Corplex Donepezil has the added benefit of potentially decreasing the rate of gastrointestinal side effects seen with existing oral formulations, such as nausea, vomiting and loss of appetite.

Donepezil (the active ingredient in Aricept®) is the most widely-prescribed medication in a class of Alzheimer's drugs known as cholinesterase inhibitors, and is approved for the treatment of mild, moderate and severe disease.  Donepezil is currently only available in tablet or orally disintegrating tablet form, each administered once daily, presenting compliance challenges for family members and caregivers who cannot rely on patients to consistently take their daily tablets, and is known to cause gastrointestinal side effects, including nausea, vomiting and loss of appetite.

Memantine (the active ingredient in Namenda®) is one of the most widely-prescribed medications for the treatment of moderate to severe dementia of the Alzheimer’s type.  Memantine is the only FDA-approved N-methyl-D-aspartate (“NMDA”)-receptor antagonist for use in Alzheimer’s and works by regulating the activity of glutamate, a neurotransmitter in the brain involved in learning and memory.   twice-daily oral dosage forms. As with donepezil, this presents compliance challenges for family members and caregivers who cannot rely on patients to consistently take their oral medications.

Our donepezil and memantine candidates first entered into Phase 1 clinical trials in the fourth fiscal quarter of 2015, and we announced successful results for several donepezil and memantine clinical trials throughout fiscal 2016. In April 2016, we received positive feedback from the FDA on our pre-IND submission that outlined our proposed 505(b)(2) regulatory pathway for Corplex Donepezil based solely on a demonstration of bioequivalence. Bioequivalence clinical studies are designed to assess the biological equivalence of pharmaceutical products based on their PK profiles, and are generally performed in healthy subjects.  These studies are relatively short in duration and provide a development path that is substantially less costly and more streamlined than typical clinical development programs, which require studies demonstrating safety and efficacy. Following review of our pre-IND submission, the FDA provided clear guidance on our development plans and registration pathway. The agency advised us that if we can adequately demonstrate bioequivalence between Corplex Donepezil and oral Aricept in our planned PK bioequivalence studies, additional clinical efficacy studies would not be required. 

Additionally, in August 2016, after review of our pre-IND submission of Corplex Memantine, the FDA concurred with our development plans for this product, including our proposal for pivotal studies based on the demonstration of bioequivalence between the Corplex Memantine and oral Namenda XR® extended release capsules.

In September 2016, we filed an Investigational New Drug (“IND”) Application for Corplex Donepezil following completion of required nonclinical studies. The FDA notified us in October 2016 that we may proceed with our planned bioequivalence testing, and we initiated a pilot bioequivalence study in the United States during the fourth calendar quarter of 2016. This study will evaluate steady state blood levels of once-weekly Corplex Donepezil using two different patch sizes compared to 10mg per day of oral Aricept in healthy volunteers.  We plan to use the results of this study to finalize the patch size and the number of subjects required for our pivotal bioequivalence study, which we expect to initiate in the second half of calendar 2017. 

We plan to conduct a Phase 1 PK clinical trial using an optimized formulation of our Corplex Memantine product candidate in the first half of calendar 2017.  Assuming the results of this study are positive, we expect to both file an IND for Corplex Memantine and initiate our pilot bioequivalence study for this product in the second half of calendar 2017.

Corplex Ropinerole is being developed as a once-weekly transdermal patch for the treatment of Parkinson’s disease. Parkinson’s disease is the second most common neurodegenerative disorder after Alzheimer’s disease and many Parkinson’s patients have trouble swallowing pills. Approximately one million people in the United States and from four to six million people worldwide suffer from this disease, which is commonly treated with dopamine replacement therapies such as levodopa and dopamine agonists that mimic the action of dopamine. We have performed preclinical development work on a transdermal formulation of ropinirole, a proven and FDA-approved dopamine agonist for treating Parkinson’s disease. We anticipate developing this patch under a 505(b)(2) regulatory pathway, which we believe will allow for reduced nonclinical and clinical study cost and time.

In April 2015, we entered into an agreement with Aequus to develop new transdermal products with an initial focus on neurological and psychiatric disorders. The first project under this collaboration is a multi-day transdermal formulation of aripiprazole, a drug already approved by the FDA for the treatment of a variety of psychiatric conditions.

Aequus initiated a Phase 1 bioavailability clinical trial for this product in the fourth calendar quarter of 2015, and reported positive results in the first calendar quarter of 2016.

MicroCor hPTH(1‑34) is a transdermal system designed to use our MicroCor technology to provide simplified delivery of parathyroid hormone, the active ingredient of Forteo®, an injectable product marketed by Eli Lilly and Company for the treatment of severe osteoporosis. hPTH(1‑34) is a shortened version of the naturally occurring parathyroid hormone that promotes bone growth.

We have completed Phase 1 and Phase 2a clinical studies of MicroCor hPTH(1‑34) in healthy women. In these studies, MicroCor hPTH(1‑34) was shown to be safe and well tolerated with comparable drug exposure to that achieved with the commercially available subcutaneous injections. The product achieved rapid systemic delivery of hPTH with a short wear time of five minutes. We reported successful, interim Phase 2a results in July 2015. Although we have self-funded Phase 1 and Phase 2a clinical trials for MicroCor hPTH(1‑34), we expect to partner the next phases of clinical development for this product candidate. 

We have in place facilities for manufacture of MicroCor products for early clinical testing. We have developed an aseptic manufacturing plan for large scale manufacturing, which would be required for Phase 3 and commercial production of any MicroCor products, and we expect to initiate construction of this manufacturing facility after we have an agreement in place with a partner for the commercialization of a MicroCor product or products.

Motion Sickness Patch.  We have developed a three-day generic transdermal product for the prevention of nausea and vomiting associated with motion sickness in collaboration with Teva. This product is currently the subject of a pending ANDA.

Feasibility Programs include self-funded and partner‑funded feasibility programs that we have completed or are currently in progress. For example, we have developed a preliminary formulation for our self-funded MicroCor Zolmitriptan candidate and have conducted initial feasibility studies in an animal model. In our partner-funded programs performed to date, we have collaborated with leading biopharmaceutical companies to formulate their proprietary active molecules in our Corplex and MicroCor technologies and demonstrate delivery of the drug in animal models. Additional programs are in the planning process.

Research and Development

Our research and development operations are located in a 25,000 square foot laboratory and office facility in Menlo Park, California that is configured for transdermal and transmucosal systems development. We conduct proprietary drug delivery research utilizing our extensive experience in polymer blending, formulations and system engineering to produce innovative products with high drug delivery efficiency. Our research and development team has full early product development capabilities, including:

In addition, our Menlo Park site operates a facility capable of making products in accordance with current good manufacturing practice (“cGMP”) requirements for certain Phase 1 and Phase 2 clinical studies.

Our Menlo Park research and development team includes 29 scientists and engineers, some of whom were original inventors of transdermal patches. We perform the formulation system design, analytical method development and prototyping for all of our transdermal products. Our research and development team works in collaboration with the process scale‑up team in our manufacturing operations early in the product development cycle. This early coordination helps assure streamlined technology transfer success in the final scale‑up and commercial manufacture of each product, leading to more robust development programs and greater manufacturing efficiencies.

Manufacturing

Our commercial manufacturing facilities are located in Grand Rapids, Michigan in three buildings comprising approximately 200,000 square feet. We have a full range of development and manufacturing capabilities, from complete process development and scale‑up services to commercial manufacture. We have made significant investments in our manufacturing technology that allow us to automate many of our processes and maximize the productivity of our labor force. We employ multiple manufacturing techniques, including solvent cast and extrusion manufacturing processes that minimize the thickness of our patches and reduce the costs of our products. Solvent casting is well‑suited for manufacturing films containing heat‑sensitive molecules because the temperatures required to remove the solvents are relatively low compared to those needed for a hot‑melt extrusion process. Hot‑melt extrusion is not suitable for ingredients that could be thermally degraded in the process, but is environmentally friendly, cost effective and more flexible than solvent cast‑only processes.

Our manufacturing platform includes:

Our facilities are FDA and DEA registered, and ISO9001 and ISO13485 certified. Our manufacturing facilities in Grand Rapids are licensed to manufacture over-the-counter (“OTC”) products, consumer products, prescription transdermal, dermal and mucosal products, as well as wound care products. Our Grand Rapids facilities also have the capacity to produce over 100 million patches annually and can be expanded as our needs grow. A number of our equipment lines have been fully funded by our partners to support the development of partnered products. In these cases, the partners retain title to those equipment lines, while we retain responsibility for maintaining and operating them. Our operations include on‑site quality control laboratories and testing procedures, quality assurance systems, and internal audit procedures for our processes and equipment.

Intellectual Property

Our success depends on our ability to obtain patents and protect our trade secrets and know‑how. We must be able to operate without infringing on any other company’s intellectual property and we must prevent others from infringing our intellectual property. Our strategy is to protect our intellectual property by filing both U.S. and international patents related to our proprietary technologies, products, inventions and improvements that are important to

our business. As of September 30, 2016, we held 52 U.S. issued patents and 187 foreign issued patents (which include granted European patents rights that have been validated in various EU member states) and 31 U.S. pending patents and 94 foreign pending patents relating to our Corplex and MicroCor technologies and products.  Our patent portfolio includes composition of matter, use and process patents, which cover both our proprietary technology platforms and specific products and product candidates. Our issued U.S. patents and patent applications will expire between 2019 and 2036. Some of the issued patents and pending patent applications, if issued, may also be eligible for patent term adjustment and patent term restoration, thereby extending their patent terms.

Proprietary rights for our products in development and our potential products will be protected from use by third parties only to the extent that they are covered by valid and enforceable patents or are effectively maintained as trade secrets. Patents owned by us (or licensed by us) may not protect us from competition in the future and our pending patent applications may not result in patent rights being issued. In addition, the laws of certain foreign countries may not protect our intellectual property rights to the same extent as they do under U.S. law.

Our products in development may be covered by third party patents or other intellectual property rights, in which case we would need to obtain a license to continue to develop and/or market these products. Such licenses may not be available on acceptable terms and such licenses may not be attainable, which could delay product launches if we are required to design around a patent. Litigation may be necessary to defend against or assert claims of infringement to enforce patents, protect trade secrets or know‑how or to determine validity in order to freely sell a product in the marketplace. In addition, interference, derivation, post‑grant oppositions or other proceedings may be necessary to determine rights to inventions in our patents. Litigation could entail substantial financial costs and may have a material adverse effect on our business, financial condition or results of operations.

In certain circumstances, we rely on trade secrets to protect our technology. Trade secrets are difficult to protect. Generally, we protect our proprietary processes and manufacturing as trade secrets and we secure confidentiality agreements from all of our employees, contractors, consultants and advisors. We cannot assure that the agreements will not be breached, or that we will be able to remedy such a breach, or that our trade secrets will not become known in the public domain and be discovered by our competitors. Disputes may also arise with respect to know‑how and inventions created by our employees, contractors and consultants. See the section entitled “Risk Factors—Risks Related to Our Intellectual Property.”

Regulatory

Food and Drug Administration.  The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinical development, manufacture and marketing of pharmaceutical and consumer cosmetic products. These agencies and other federal, state and local entities regulate research and development activities and the testing, manufacture, quality control, safety, effectiveness, labeling, storage, distribution, record keeping, approval, advertising and promotion of our products. Many of our products are combination drug‑device products that are regulated as drugs by the FDA, with consultations from the device center in the FDA. Others, such as consumer teeth whitening products, are regulated by the FDA as cosmetics. Failure to comply with applicable FDA or other requirements may subject a company to a variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending applications, a clinical hold, warning letters, recall or seizure of products, partial or total suspension of production, withdrawal of the product from the market, injunctions, fines, civil penalties or criminal prosecution.

FDA Regulation of Drugs.  The process required by the FDA under the new drug provisions of the Federal Food, Drug, and Cosmetic Act (the “FFDC Act”) before our investigational drugs may be marketed in the United States generally involves the following:

Preclinical tests include laboratory evaluation of the investigational drug, its chemistry, formulation and stability, as well as animal studies to assess its potential safety and efficacy. For human clinical trials to be conducted in the United States, we must generally submit the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of an IND, which must become effective before we may begin human clinical trials. An IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30‑day time period, raises concerns or questions about the conduct of the trials as outlined in the IND and imposes a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. Our submission of an IND may not result in FDA authorization to commence clinical trials. Further, an independent Institutional Review Board (an “IRB”) at each medical center proposing to conduct the clinical trials must review and approve any clinical study as well as the related informed consent forms and authorization forms that permit us to use individually identifiable health information of study participants.

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objective of the study, the parameters to be used in monitoring safety, and the efficacy criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. The IRB must monitor the study until completed. There are also requirements governing the reporting of ongoing clinical trial results to public registries.

The foregoing discussion of clinical trials applies to clinical trials conducted under an IND. In some instances, we may conduct clinical trials outside of the United States, which may require different or additional regulatory submissions depending on the country in which the trial is conducted.

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

We cannot be certain that we will successfully complete Phase 1, Phase 2 or Phase 3 clinical trials of our investigational drugs within any specific time period, if at all. Furthermore, the FDA or the IRB or the sponsor may suspend or terminate clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Sponsors of clinical trials may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate. During the clinical development of products, sponsors may meet and consult with the FDA in an effort to ensure that the design of their studies will likely provide data both sufficient and relevant for later regulatory approval; however, no assurance of approvability can be given by the FDA.

The results of product development, preclinical studies and clinical studies are submitted to the FDA as part of an NDA for approval of the marketing and commercial shipment of the product. Submission of an NDA requires the payment of a substantial user fee to the FDA, and although the agency has defined user fee goals that govern the length of an NDA’s review time, we cannot assure that the FDA will make a review decision in any particular timeframe. After the FDA evaluates the NDA and conducts inspections of manufacturing facilities where the drug product and/or its active pharmaceutical ingredient will be produced, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete but the application is not ready for approval. A Complete Response Letter may require additional clinical data and/or one or more additional clinical trials, as the FDA has required of our partner Agile, and/or other requirements related to clinical trials, preclinical studies or manufacturing, any of which may be expensive and require considerable time to complete. Even if such data are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval.

After approving a drug, the FDA may withdraw product approval if compliance with regulatory standards is not maintained or if safety problems occur after the product reaches the market. Requirements for additional Phase 4 studies (post‑approval marketing studies) to confirm safety and effectiveness in a broader commercial use population may be imposed as a condition of marketing approval. In addition, the FDA requires surveillance programs to monitor approved products that have been commercialized, and the agency has the power to require changes in labeling or to prevent further marketing of a product based on the results of these post‑marketing programs.

Satisfaction of FDA requirements or similar requirements of state, local and foreign regulatory agencies typically takes several years, and the actual time required may vary substantially based upon the type, complexity and novelty of the pharmaceutical product. Government regulation may delay or prevent marketing of potential products for a considerable period of time and impose costly procedures upon our activities. We cannot be certain that the FDA or any other regulatory agency will grant approval for any of our pharmaceutical systems under development on a timely basis, if at all. Success in preclinical or early stage clinical trials does not assure success in later stage clinical trials. Data obtained from preclinical and clinical activities is not always conclusive and may be susceptible to varying interpretations which could delay, limit or prevent regulatory approval. Evolving safety concerns can result in the imposition of new requirements for expensive and time consuming tests. Even if a product receives regulatory approval, the approval may be significantly limited to specific indications. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. Any pharmaceutical systems that we may develop and obtain approval for would also be subject to adverse findings of the active drug ingredients being marketed in different dosage forms and formulations. Delays in obtaining, or failures to obtain regulatory approvals would have a material adverse effect on our business. Marketing our pharmaceutical systems abroad will require similar regulatory approvals and is subject to similar risks. In addition, we cannot predict what adverse governmental regulations may arise from future U.S. or foreign governmental action. Currently, our partners are the NDA and ANDA holders of products that we develop with them, and therefore our partners communicate with FDA with respect to these applications.

Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including cGMP requirements, and reporting of adverse experiences with the drug. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and state

agencies, and are subject to periodic announced and unannounced inspections by the FDA and state agencies for compliance with cGMP regulations, which impose procedural and documentation requirements upon us and our third party manufacturers. In addition, changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon us and any third‑party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. We cannot be certain that we or our present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory requirements.

Future FDA and state inspections may identify compliance issues at our facilities or at the facilities of our suppliers of raw materials that may disrupt production or distribution, or require substantial resources to correct. In addition, discovery of previously unknown problems with a product or the failure to comply with applicable requirements may result in restrictions on a product, manufacturer or holder of an approved NDA, including withdrawal or recall of the product from the market or other voluntary, FDA‑initiated or judicial action that could delay or prohibit further marketing. For example, in 2008 and 2010 we conducted recalls of our fentanyl products and were inspected by the FDA. These inspections led to the issuance of FDA Forms 483 identifying inspectional observations. The most recent FDA inspection of our facility was a pre‑approval inspection for a product that is the subject of pending ANDA. The FDA issued a Form 483 with one observation, which we addressed as part of our ongoing obligations under the FDA’s quality system regulation.

The FDA regulates drug labeling and promotion activities. The FDA has actively enforced regulations prohibiting the marketing of products for unapproved uses, and federal and state authorities are also actively litigating against sponsors who promote their drugs for unapproved uses under various fraud and abuse and false claims act statutes. We and our pharmaceutical systems are also subject to a variety of state laws and regulations in those states or localities where our pharmaceutical systems are or will be marketed. Any applicable state or local regulations may constrain our ability to market our pharmaceutical systems in those states or localities. We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potentially hazardous substances. We may incur significant costs to comply with such laws and regulations now or in the future.

The FDA’s policies may change and additional government regulations may be enacted which could prevent or delay regulatory approval of our drug product candidates. Moreover, increased attention to the containment of health care costs in the United States and in foreign markets could result in new government regulations that could have a material adverse effect on our business. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

The FDA also has the authority to require a risk evaluation and mitigation strategy (“REMS”) to ensure the safe use of a drug. The FDA has authority to require a REMS under the Food and Drug Administration Amendments Act of 2007 when necessary to ensure that the benefits of a drug outweigh the risks. In determining whether a REMS is necessary, the FDA must consider the size of the population likely to use the drug, the seriousness of the disease or condition to be treated, the expected benefit of the drug, the duration of treatment, the seriousness of known or potential adverse events, and whether the drug is a new molecular entity. If the FDA determines a REMS is necessary, the drug sponsor must agree to the REMS plan at the time of approval. A REMS may be required to include various elements, such as a medication guide or patient package insert, a communication plan to educate health care providers of the drug’s risks, limitations on who may prescribe or dispense the drug, or other measures that the FDA deems necessary to assure the safe use of the drug. In addition, the REMS must include a timetable to assess the strategy at 18 months, three years, and seven years after the strategy’s approval. The FDA may also impose a REMS requirement on a drug already on the market if the FDA determines, based on new safety information, that a REMS is necessary to ensure that the drug’s benefits outweigh its risks.

On July 9, 2012, the FDA approved a REMS for extended‑release and long‑acting opioid medications. Several of our currently marketed drug products and investigational drugs, including fentanyl, are subject to the REMS. There may be increased cost, administrative burden and potential liability associated with the marketing and sale of drugs

subject to the REMS requirement, which could negatively impact the commercial benefits to us and our partners from the sale of these drug products and, if approved, drug product candidates. Our partners, as the holders of the marketing applications for the affected drugs, are responsible for compliance with the opioid REMS requirements.

Hatch‑Waxman Act.  Section 505 of the FFDC Act describes three types of NDAs that may be submitted to the FDA to request marketing authorization for a new drug. A Section 505(b)(1) NDA is an application that contains full reports of investigations of safety and effectiveness. The Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch‑Waxman Act, created two additional marketing pathways under Sections 505(b)(2) and 505(j) of the FFDC Act. A 505(b)(2) NDA is an application that contains full reports of investigations of safety and effectiveness but where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. This regulatory pathway enables the applicant to rely, in part, on the FDA’s findings of safety and efficacy for an existing product, called the Reference Listed Drug (“RLD”), or on published literature, in support of its application. Section 505(j) establishes an abbreviated approval process for a generic version of approved drug products through the submission of an ANDA. An ANDA provides for marketing of a generic drug product that has the same active ingredients, dosage form, strength, route of administration, labeling, performance characteristics and intended use, among other things, to a previously approved product. ANDAs are termed “abbreviated” because they are generally not required to include preclinical (animal) and clinical (human) data to establish safety and effectiveness. Instead, generic applicants must scientifically demonstrate that their product is bioequivalent to (i.e., performs in the same manner as) the innovator drug. The generic version generally must deliver approximately the same amount of active ingredients into a patient’s bloodstream in the same amount of time as the innovator drug.

Although there is no clear published FDA guidance on whether bioequivalence studies can be relied on for approval of a transdermal formulation under the Section 505(b)(2) regulatory pathway where the RLD is an oral dosage form, we have received written feedback from the FDA on our pre-IND submissions for both Corplex Donepezil and Corplex Memantine confirming that a 505(b)(2) regulatory pathway based solely on a demonstration of bioequivalence is acceptable for each of these product candidates.  Based on this guidance, we expect to make a direct transition from a pilot bioequivalence study to a single pivotal bioequivalence study in healthy volunteers, saving expense and time.

Upon submission of an ANDA or a 505(b)(2) NDA, an applicant must certify to the FDA that (1) no patent information on the drug product that is the subject of the application has been submitted to the FDA; (2) such patent has expired; (3) the date on which such patent expires; or (4) such patent is invalid or will not be infringed upon by the manufacture, use or sale of the drug product for which the application is submitted. This last certification is known as a paragraph IV certification. If the paragraph IV certification is challenged by an NDA holder or the patent owner(s) asserts a patent challenge to the paragraph IV certification, the FDA may not approve that application until the earlier of 30 months from the receipt of the notice of the paragraph IV certification, the expiration of the patent, when the infringement case concerning each such patent was favorably decided in the applicant’s favor or such shorter or longer period as may be ordered by a court. This prohibition is generally referred to as the 30‑month stay. In instances where an ANDA or 505(b)(2) NDA applicant files a paragraph IV certification, the NDA holder or patent owner(s) regularly take action to trigger the 30 month stay, recognizing that the related patent litigation may take many months or years to resolve. Thus, approval of an ANDA or 505(b)(2) NDA could be delayed for a significant period of time depending on the patent certification the applicant makes and the reference drug sponsor’s decision to initiate patent litigation.

The Hatch‑Waxman Act establishes periods of regulatory exclusivity for certain approved drug products, during which the FDA cannot approve (or in some cases accept) an ANDA or 505(b)(2) application that relies on the branded reference drug. For example, the holder of an NDA may obtain five years of exclusivity upon approval of a new drug containing a new chemical entity that has not been previously approved by the FDA. The Hatch‑Waxman Act also provides three years of marketing exclusivity to the holder of an NDA (including a 505(b)(2) NDA) for a particular condition of approval, or change to a marketed product, such as a new formulation for a previously approved product, if one or more new clinical studies (other than bioavailability or bioequivalence studies) was essential to the approval of the application and was conducted/sponsored by the applicant. This three‑year exclusivity period protects against FDA approval of ANDAs and 505(b)(2) NDA for drugs that include the innovation that required the new clinical data.

We expect that most of our drug candidates will utilize the section 505(b)(2) regulatory pathway. Even though several of our drug products utilize active drug ingredients that are commercially marketed in the United States in other dosage forms, we need to establish safety and effectiveness of those active ingredients in the formulation and dosage forms that we are developing. We also have several partnered products that are approved pursuant to ANDAs or will be filed under the ANDA pathway. All approved products, both innovator and generic, are listed in FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book).

We have begun consultations with a small number of non-U.S. regulatory bodies to determine whether regulatory approval based upon bioequivalence would be possible, however we have not yet received formal feedback on the availability of a regulatory pathway based on the demonstration of bioequivalence outside the United States. If non-U.S. regulatory bodies determine that an abbreviated pathway based on the demonstration of bioequivalence is not available, we will need to perform expensive, time-consuming preclinical tests and/or clinical trials, potentially including clinical efficacy and safety studies to seek regulatory approval in the relevant non-U.S. jurisdictions and, if we are unable to perform these studies or obtain regulatory approval, we will not be able to commercialize our Alzheimer’s product candidates in these jurisdictions.

The Drug Enforcement Administration.  Certain of our products, including our fentanyl patch, are regulated as a “controlled substance” as defined in the Controlled Substances Act of 1970 (the “CSA”), which establishes registration, security, recordkeeping, reporting, storage, distribution and other requirements administered by the Drug Enforcement Administration (the “DEA”). The DEA is concerned with the control and handling of controlled substances, and with the equipment and raw materials used in their manufacture and packaging, in order to prevent loss and diversion into illicit channels of commerce.

The DEA regulates controlled substances as Schedule I, II, III, IV or V substances, with Schedule II substances considered to present the highest risk of substance abuse and Schedule V substances the lowest risk. Certain active ingredients are listed by the DEA as Schedule II and Schedule III under the CSA. 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, generally physically presented to a pharmacist and may not be refilled without a new prescription. Furthermore, the amount of Schedule II substances we can obtain for clinical trials and commercial distribution is limited by the DEA in accordance with a quota system and our quota may not be sufficient to complete clinical trials or meet commercial demand. The DEA establishes annually an aggregate quota for how much fentanyl may be produced in total in the United States based on the DEA’s estimate of the quantity needed to meet legitimate scientific and medicinal needs. This limited aggregate amount of fentanyl that the DEA allows to be produced in the United States each year is allocated among individual companies, who must submit applications annually to the DEA for individual production and procurement quotas. We must receive an annual quota from the DEA in order to produce or procure any Schedule II substance, including fentanyl for use in manufacturing our fentanyl products. The DEA may adjust aggregate production quotas and individual production and procurement quotas from time to time during the year, although the DEA has substantial discretion in whether or not to make such adjustments.

Annual registration is required for any facility that manufactures, distributes, dispenses, imports or exports any controlled substance. The registration is specific to the particular location, activity and controlled substance schedule. For example, separate registrations are needed for import and manufacturing, and each registration will specify which schedules of controlled substances are authorized.

The DEA typically inspects a facility to review its security measures prior to issuing a registration. Security requirements vary by controlled substance schedule, with the most stringent requirements applying to Schedule I and Schedule II substances. Required security measures include background checks on employees and physical control of inventory through measures such as cages, surveillance cameras and inventory reconciliations. Records must be maintained for the handling of all controlled substances, and periodic reports made to the DEA, for example distribution reports for Schedule I and II controlled substances, Schedule III substances that are narcotics, and other designated substances. Reports must also be made for thefts or losses of any controlled substance, and to obtain authorization to destroy any controlled substance. In addition, special authorization and notification requirements apply to imports and exports.

Failure to maintain compliance with applicable requirements, particularly as manifested in loss or diversion, can result in enforcement action that could have a material adverse effect on our business, results of operations and financial condition. The DEA may seek civil penalties, refuse to renew necessary registrations, or initiate proceedings to revoke those registrations. In certain circumstances, violations could result in criminal proceedings. Individual states also regulate controlled substances, and we and our partners will be subject to state regulation on distribution of these products.

There is a risk that DEA regulations may interfere with the supply of the drugs used in our clinical trials and sold commercially, and, thus on our ability to produce and distribute our products in the volume needed to meet clinical and commercial demand.

FDA Regulation of Consumer Cosmetic Products.  Consumer teeth whitening products are regulated by the FDA as cosmetics. The processing, formulation, safety, manufacturing, packaging, labeling, advertising and distribution of these products are subject to regulation by one or more federal agencies, including the FDA and the FTC, and by various agencies of the states and localities in which these products are sold. Cosmetic products and their ingredients do not require premarket approval prior to sale, but are subject to specific labeling regulations. While the FDA has not promulgated specific cGMPs for the manufacture of cosmetics, the FDA has provided guidelines for cosmetic manufacturers to follow to ensure that their products are neither misbranded or adulterated.

The FTC exercises jurisdiction over the advertising of cosmetics. In recent years, the FTC has instituted numerous enforcement actions against companies for failure to have adequate substantiation for claims made in advertising or for the use of false or misleading advertising claims. We are also subject to regulation under various state, local, and international laws that include provisions governing, among other things, the formulation, manufacturing, packaging, labeling, advertising, and distribution of cosmetics.

Other Healthcare Laws.  Although we do not directly market or promote any of our products, we and our partners are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our business. Such laws may include, without limitation: (a) federal and state laws relating to the Medicare and Medicaid programs and any other federal healthcare program; (b) federal and state laws relating to healthcare fraud and abuse, including, without limitation, the federal Anti‑Kickback Statute (42 U.S.C. § 1320a‑7b(b)), the federal False Claims Act (31 U.S.C. §§ 3729 et seq.), the False Statements Statute, (42 U.S.C. § 1320a‑7b(a)), the Exclusion Laws (42 U.S.C. § 1320a‑7), the federal Physician Payment Sunshine Act (42 U.S.C. § 1320a‑7h), the Anti‑Inducement Statute (42 U.S.C. § 1320a‑7a(a)(5)), the Civil Monetary Penalties Law (42 U.S.C. § 1320a‑7a) and criminal laws relating to healthcare fraud and abuse, including but not limited to 18 U.S.C. §§ 286, 287 and 1001, and the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) (Pub.L. 104‑191); (c) state laws relating to Medicaid or any other state healthcare or health insurance programs; (d) federal or state laws relating to billing or claims for reimbursement submitted to any third party payor, employer or similar entity, or patient; (e) any other federal or state laws relating to fraudulent, abusive or unlawful practices connected in any way with the provision or marketing of healthcare items or services, including laws relating to the billing or submitting of claims for reimbursement for any items or services reimbursable under any state, federal or other governmental healthcare or health insurance program or any private payor; and (f) federal and state laws relating to health information privacy and security, including HIPAA, and any rules or regulations promulgated thereunder, and the Health Information Technology for Economic and Clinical Health Act, enacted as part of the American Recovery and Reinvestment Act of 2009 and any regulations promulgated thereunder. If our operations or our partners’ operations and practices are found to be in violation of any of such laws or any other governmental regulations that apply to us or our partners, we may be subject to penalties, including civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, the exclusion from participation in federal and state healthcare programs and imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

Coverage and Reimbursement.  Sales of our products marketed by our partners will depend, in part, on the extent to which our products will be covered by third‑party payors, such as government health care programs, commercial insurance and managed healthcare organizations. These third‑party payors are increasingly reducing reimbursements for certain medical products and services. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost containment programs, including price controls, restrictions on

reimbursement and requirements for substitution of generic products. Adoption of price controls and cost‑containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. In the United States, there has been an increase in political support for controlling significant price increases of drug products, in particular due to high-profile cases that have gained national attention and triggered Congressional inquiries. In many European markets for pharmaceuticals, drug price controls at various levels are prevalent. In many U.S. and most major European markets there is also increased pressure on pricing and reimbursement practices relating to products that are new dosage forms of drugs that are currently available at lower cost in their original forms. For our transdermal products that incorporate active drug ingredients that are no longer patent protected, we expect that we will need to substantiate the differential benefits of our products in order to receive reimbursement at desired levels. Even if one of our transdermal products would incorporate active drug ingredients that are still patent protected, many EU Member States might still require evidence of differential benefits compared to products with different active drug ingredients. Decreases in third‑party reimbursement for our products or a decision by a third‑party payor to not cover our products could reduce or eliminate utilization of our products and have a material adverse effect on our sales, results of operations and financial condition. In addition, state and federal healthcare reform measures have been and will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products or additional pricing pressures.

Marketing and Sales

Due to the nature of our partnerships and our current business relationships, we currently do not have or require an in‑house commercial sales force or marketing function. We have a business development program that generates new business opportunities with pharmaceutical and biopharma companies, including delivering their proprietary drugs in transdermal systems to improve their therapeutic profile, extending the brand life of drugs by offering new dosage forms, and co‑developing products that we have initiated. Historically, we have partnered with pharmaceutical companies to market and sell each of the products that we develop and manufacture. In most cases, we work together with our partners to decide which products to develop. However, in some instances we selectively develop products on our own prior to partnering with another company. In the future, we may build our own commercial sales and marketing capability in certain niche markets in order to capture more of the economic value of the products that we may develop. We may also enter into co‑promotion agreements for certain of our products with our partners. We will continue to pursue strategic alliances with partners who have significant marketing and distribution presence and expertise.

Competition

Our industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We face competition from other companies in numerous industries, including pharmaceuticals and drug delivery. We believe the key competitive factors that will affect the commercial success of our products and the development of our product candidates include onset of action, bioavailability, efficacy, patent protection, compliance, cost, convenience of dosing, safety and tolerability profile.

Companies focused on delivering small molecules transdermally include 3M, Johnson & Johnson, Lohmann Therapy Systems (“LTS”), Mylan, Hisamitsu (through its subsidiary, Noven), Allergan, and Actavis/Teva. Companies operating in the microneedle transdermal field include 3M, Zosano, Theraject and Fujifilm. Several academic institutions are also conducting research in the microneedle field. In addition to microneedle technologies, there are other methods of transdermal delivery under development for biologics, including heat ablation, laser, ultrasound and radio frequency. Companies developing and manufacturing transdermal systems for biologics include Becton Dickinson, Vyteris, and Zogenix. Some of these companies may be addressing the same therapeutic areas or indications as we are.

Our current products compete, and products in development will compete, in highly competitive markets against both transdermal products and products addressing similar patient and customer needs through other delivery forms. Clonidine TDS, Fentanyl TDS and our future ANDA products will have competition from other generic pharmaceutical companies, including Mylan and Actavis/Teva, both of which have their own transdermal manufacturing capability. Other manufacturers of fentanyl patches use a different technology than ours, and although fentanyl patches made with either technology have experienced manufacturing challenges, competitors may claim their technology is

superior. The Crest Whitestrips products compete with teeth whitening products marketed by various private labels such as those at Walgreens and CVS.

Many of our existing and potential competitors have substantially greater financial, research and development, and human resources than we do, may succeed in obtaining patent protection before us, and have greater experience than we do commercializing products and developing product candidates, including obtaining FDA and other regulatory approvals for product candidates. Consequently, our competitors are applying significant resources and experience to the problems of drug delivery and transdermal drug delivery in particular. We cannot assure you that our transdermal delivery systems will compete effectively against existing and future transdermal or other delivery systems.

Employees

As of September 30, 2016 we had 212 employees, including 29 in research and development, 162 in operations and 21 in general and administrative roles. From time to time, we also employ independent contractors to support our research and development and our administrative organizations. We also hire temporary employees when needed in our manufacturing and in other groups. None of our employees are represented by a collective bargaining unit, and we have never experienced a work stoppage. We consider our relations with our employees to be good.

Risks Related to Our Business and Industry

We have limited operating revenues and a history of operational losses and may not achieve or sustain profitability.

We have incurred significant operating and net losses since our inception. For fiscal 2016, we recorded net revenues of $33.0 million and net loss of $36.7 million. For fiscal 2015, we recorded net revenues of $40.9 million and net loss of $28.5 million. For fiscal 2014, we recorded net revenues of $42.4 million and net loss of $9.9 million. As of September, 2016, we had stockholders’ equity of $2.9 million. We expect to continue to incur net operating losses for at least the next several years as we seek to advance our products through clinical development and regulatory approval, prepare for and, if approved, proceed to further commercialization, and expand our operations. Our ability to generate sufficient revenues from our existing products or from any of our product candidates in development, and to transition to profitability and generate consistent positive cash flow is uncertain, and we may continue to incur losses and negative

cash flow and may never transition to profitability or positive cash flow. In particular, we expect our operating expenses and research and development expenses to continue to increase in the near‑term as we expand our operations and continue to invest in our proprietary technologies and products, and may not be able to generate sufficient revenues to offset this anticipated increase in expenses.

We are dependent on the commercial success of our Clonidine TDS, Fentanyl TDS and Crest Whitestrips, and although we are generating revenues from sales of our products, there may be a decline in revenues generated by our Clonidine TDS and Fentanyl TDS products. 

We anticipate that, in the near term, our ability to become profitable will depend upon the commercial success of the products marketed by our partners. To date, we have generated limited revenues from sales of these products and, in addition, we have incurred liability in the past in association with product recalls of Fentanyl TDS. Our Fentanyl TDS product revenues in fiscal 2016 and fiscal 2015 were $6.4 million and $9.1 million, respectively. In June 2015, we amended our transdermal fentanyl agreements with Par, a wholly-owned subsidiary of Endo, to amend the pricing and payment provisions and other business terms in exchange for, among other things, the termination of Par’s exclusive rights to products other than the fentanyl reservoir patch currently being manufactured by us for Par. The amended terms also include the elimination of the royalty obligations on purchase orders placed after June 2015 and establish mutually agreeable transfer pricing. Our product revenues from Fentanyl TDS declined in fiscal 2016 compared to fiscal 2015 as a result of the amended terms of these agreements and the continued impact of increased competition from other generic companies. We expect that our product revenues from Fentanyl TDS in fiscal 2017 will be lower than fiscal 2016 as a result of the continued impact of increased competition.

Fentanyl TDS also relies on a reservoir patch design instead of a matrix patch design. Although both reservoir and matrix patches have been subject to safety concerns and recalls in the past, our current competitors, most of whom use a matrix patch, may raise questions about the design and safety of a reservoir patch and the FDA may decide that the current reservoir patch design is a less safe design and may require the use of matrix patch technology instead. This would result in a more substantial decrease in our revenues and harm our operating results.

Our product revenues from Clonidine TDS in fiscal 2016 and fiscal 2015 were $6.8 million and $6.8 million, respectively. The product revenues in fiscal 2016 remained consistent with those of fiscal 2015 as market share stabilized in the three-competitor marketplace. Fewer units sold and decreased unit pricing by Teva and Mayne directly reduces our profit sharing revenues. In August 2016, Teva completed its acquisition of the generic business of Allergan, which resulted in the divestiture of the Clonidine TDS product to Mayne, which could impact our product revenues for this product for fiscal 2017 and beyond as described in further detail in “—Continued consolidation in the pharmaceutical industry, and particularly in the generic pharmaceutical industry, could impact our existing partnerships, products and product candidates.”

In addition to the risks discussed elsewhere in this section, our ability to continue to generate revenues from our commercialized products will depend on a number of factors, including, but not limited to:

Because of the numerous risks and uncertainties associated with our commercialization efforts, including our reliance on our partners for the marketing and distribution of our products, and other factors, we are unable to predict the extent to which we will continue to generate revenues from our products, or the timing for when or the extent to which we will become profitable. Even if we do achieve profitability, we may not be able to sustain or increase profitability on an ongoing basis.

We depend on a few partners for a significant amount of our revenues, and if we lose any of our significant partners, our business could be harmed.

The majority of our revenues come from only a few partners. For fiscal 2016, three partners, Teva/Mayne, Endo and P&G, individually comprised approximately 22%, 20%, and 42%, respectively, of our total revenues. We expect that revenues from a limited number of partners will continue to account for a large portion of our revenues in the future. The loss by us of any of these partners or a material reduction in their purchases or their market pricing could harm our business, results of operations, financial condition and prospects. In addition, if any of these partners were to fail to pay us in a timely manner, it could harm our cash flow.

We or our partners may choose not to continue developing or commercializing a product or product candidate at any time during development or after approval, which would reduce or eliminate our potential return on investment for that product or product candidate.

We currently have seven products on the market, two of which are drugs approved under Abbreviated New Drug Applications (“ANDAs”), and five consumer products. In addition, two drug product candidates that we have developed in partnership with other companies are the subject of pending applications for approval by the FDA and we have several self‑funded drug product candidates in preclinical and clinical stages of research and development.

At any time, we or our partners may decide to discontinue the development of a marketed product or drug product candidate or not to continue commercializing a marketed product or a drug product candidate for a variety of reasons, including the appearance of new technologies that make our product obsolete, the position of our partner in the market, competition from a competing product, failure of our partners or us to design and conduct successful clinical trials or obtain regulatory approval for our product candidates, or changes in or failure to comply with applicable regulatory requirements. If we terminate a program in which we have invested significant resources, we will not receive any return on our investment and we will have missed the opportunity to have allocated those resources to potentially more productive uses. If one of our partners terminates a development program or ceases to market an approved or commercial product, we will not receive any future milestone payments, royalties or transfer payments relating to that program or product under our partnership agreement with that party.

Our near‑term product revenue growth heavily relies on the success of the Twirla contraceptive patch.

The near‑term growth of our product revenues heavily relies on the approval and successful launch of Agile’s product candidate, the Twirla® contraceptive patch, also referred to as AG200‑15. Our collaboration partner Agile, who is responsible for funding and conducting all clinical trials for Twirla, has conducted Phase 3 clinical studies and filed a New Drug Application (an “NDA”) with the FDA for Twirla in April 2012. The FDA issued a “Complete Response Letter” in February 2013, identifying certain issues, including a request for additional clinical data, which must be addressed before approval can be granted. Accordingly, Agile has recently completed an additional Phase 3 clinical trial, and expects to announce top-line data in early January 2017. We cannot assure you that the results of this trial will be positive or that Agile will be able to ultimately obtain regulatory approval for the Twirla product. If Agile fails to achieve any of these critical activities, or experiences significant delays in doing so, our near‑term growth prospects

would be limited, and would create uncertainty around the value and usefulness of the Twirla manufacturing facility and equipment.

Since 2003, we have devoted substantial resources to the development of the Twirla contraceptive patch in collaboration with Agile. The success of the Twirla product is a key component of our business growth over the next few years and we have projected we will receive revenues from scale-up and manufacture of this product beginning in calendar 2017. The Twirla product requires a process step that has been incorporated into the commercial production line, which involves the laser‑etching of label information on each patch. In addition to requiring an additional Phase 3 clinical study, the FDA has requested information relating to this laser‑etching process to demonstrate that it does not adversely affect the performance of the patch, which we have provided to Agile in response to this request. If this product is not approved and launched in accordance with Agile’s plans, we will not realize our anticipated near-term revenue growth. In addition, one of our three buildings in our manufacturing facility in Grand Rapids, Michigan has been built out for the anticipated commercial production of Twirla. Although some of the equipment used in that building may be repurposed for other uses with Agile’s permission, it would be expensive and time consuming to do so. If Twirla is not approved, our business and financial prospects will be significantly harmed.

We are dependent on numerous third parties in our supply chain for the commercial supply of our products, and if we fail to maintain our supply relationships with these third parties, develop new relationships with other third parties or suffer disruptions in supply, we may be unable to continue to commercialize our products or to develop our product candidates.

We rely on a number of third parties for the supply of active ingredients and other raw materials for our products and the clinical supply of our product candidates. Our ability to commercially supply our products and to develop our product candidates depends, in part, on our ability to obtain successfully the active pharmaceutical ingredients used in the products, in accordance with regulatory requirements and in sufficient quantities for commercialization and clinical testing. If we fail to develop and maintain supply relationships with these third parties, we may be unable to continue to commercialize our products, or develop any other product candidates or our MicroCor systems.

We also rely on certain third parties as the current sole source of the materials they supply. Although many of these materials are produced in more than one location or are available from another supplier, if any of these materials becomes unavailable to us for any reason, we likely would incur added costs and delays in identifying or qualifying replacement materials and there can be no assurance that replacements would be available to us on acceptable terms, or at all. In certain cases, we may be required to obtain regulatory approval to use alternative suppliers, and this process of approval could delay production of our products or development of product candidates indefinitely.

If our third‑party suppliers fail to deliver the required commercial quantities of sub‑components and starting materials, on a timely basis and at commercially reasonable prices, and we are unable to find one or more replacement suppliers capable of production at a substantially equivalent cost in substantially equivalent volumes and quality, and on a timely basis, the continued commercialization of our products and the development of our product candidates would be impeded, delayed, limited or prevented, which could harm our business, results of operations, financial condition and prospects.

We face intense competition, in both our delivery systems and products, including from generic drug products, and if our competitors market or develop alternative treatments that are approved more quickly or marketed more effectively than our product candidates or are demonstrated to be safer or more effective than our products, our commercial opportunities will be reduced or eliminated.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on developing proprietary therapeutics. We face competition from a number of sources, such as pharmaceutical companies, generic drug companies, biotechnology companies, drug delivery companies and academic and research institutions, many of which have greater financial resources, marketing capabilities, salesforces, manufacturing capabilities, research and development capabilities, experience in obtaining regulatory approvals for drug product candidates and other resources than us.

Many pharmaceutical companies are developing transdermal drug delivery systems, including 3M, Johnson & Johnson, Lohmann Therapie-Systeme, Mylan, Hisamitsu (through its subsidiary, Noven), and Actavis/Teva. In the field of microneedle transdermal systems, other participants include 3M, Zosano, Theraject, Fujifilm and several academic institutions. Several of these competitors may also partner with larger pharmaceutical companies, which could provide them with significantly increased resources to develop and market their products.

We also face competition from third parties in obtaining allotments of fentanyl and other controlled substances under applicable annual quotas of the Drug Enforcement Administration (the “DEA”), recruiting and retaining qualified personnel, establishing clinical trial sites and enrolling patients in clinical trials, and in identifying and acquiring or in‑licensing new products and product candidates.

Our competitors may develop products that are more effective, better tolerated, subject to fewer or less severe side effects, more useful, more widely-prescribed or accepted, or less costly than ours. In addition, since transdermal products are worn by patients over an extended time period compared to other dosage forms, they need to be acceptable to patients and caregivers in terms of ease of use, comfort and wearability. For each product we commercialize, sales and marketing efficiency, payor reimbursement and formulary access are likely to be significant competitive factors. We do not have internal sales or marketing departments, and there can be no assurance that we can develop or contract out these capabilities in a manner that will be cost‑efficient and competitive with the sales and marketing efforts of our competitors, especially because some or all of those competitors could expend greater economic resources than we do and/or employ third‑party sales and marketing channels. Such competition can lead to reduced market share for our products and contribute to downward pressure in our pricing, which could harm our business, results of operations, financial condition and prospects.

Continued consolidation in the pharmaceutical industry, and particularly in the generic pharmaceutical industry, could impact our existing partnerships, products and product candidates and cause disruption in our business. 

Our Fentanyl TDS and Clonidine TDS products, as well as several of our product candidates, compete within the pharmaceutical industry, and particularly within the generic pharmaceutical industry. There are a limited number of companies with sufficient scale and commercial reach to effectively market these products. Recent trends in this industry are toward additional market consolidation, further concentrating financial, technical and market strength and increasing competitive pressure in the industry. For example, in August 2016, Teva completed the acquisition of the generic business of Allergan and the FTC required that Teva divest certain products, including the Clonidine TDS product that we manufacture for Teva. If Mayne, the acquiring party, is less effective in its commercialization of this product than Teva, it may result in a loss of market share or reduced pricing, either of which would adversely affect our operating results. For other products and product candidates, increased consolidation could lead to other divestitures, more intense competition and pricing pressure, and the potential discontinuation of funding for development-stage programs. Any of these events could result in a decrease in our revenues, harm our operating results or otherwise disrupt our business.

We face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.

The commercial use of our products and clinical use of our product candidates expose us to the risk of product liability claims. This risk exists even if a product is approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA, such as the case with Fentanyl TDS and Clonidine TDS, or an applicable foreign regulatory authority. Our products and product candidates are designed to affect important bodily functions and processes. Any side effects, manufacturing defects, misuse or abuse associated with our products or our product candidates could result in injury to a patient or even death. We have had 19 past legal proceedings related to Fentanyl TDS, all of which have been settled and dismissed with prejudice. We cannot offer any assurance that we will not face other product liability suits in the future, nor can we assure you that our insurance coverage will be sufficient to cover our liability under any such cases.

Fentanyl TDS is an opioid pain reliever that contains fentanyl, which is a regulated “controlled substance” under the Controlled Substances Act of 1970 (the “CSA”), and could result in harm to patients relating to its potent effects as an opioid drug and its potential for abuse. In addition, a liability claim may be brought against us even if our products or product candidates merely appear to have caused an injury. Product liability claims may be brought against

us by consumers, health care providers, pharmaceutical companies or others selling or otherwise coming into contact with our products or product candidates, among others. If we cannot successfully defend ourselves against product liability claims we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:

We have obtained product liability insurance coverage separately for fentanyl and our other commercial products and clinical trials, with a $10 million per occurrence and a $20 million annual aggregate coverage limit. Our insurance coverage may not be sufficient to cover all of our product liability related expenses or losses and may not cover us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost, in sufficient amounts or upon adequate terms to protect us against losses due to product liability. If we determine that it is prudent to increase our product liability coverage based on sales of our products, approval of other product candidates, or otherwise, we may be unable to obtain this increased product liability insurance on commercially reasonable terms or at all. Large judgments have been awarded in class action or individual lawsuits based on drugs that had unanticipated side effects, including side effects that are less severe than those of our products and our product candidates. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could decrease our cash and could harm our business, results of operations, financial condition and prospects.

We have been subject to product recalls in the past, and may be subject to additional product recalls in the future that could harm our reputation and could negatively affect our business.

We may be subject to product recalls, withdrawals or seizures if any of the products we formulate, manufacture or sell fail to meet their specifications or are believed to cause injury or illness or if we are alleged to have violated governmental regulations in the manufacture, labeling, promotion, sale, or distribution of any of our products. In 2008 and 2010, Actavis voluntarily recalled certain lots of Fentanyl TDS due to imperfections in our manufacturing processes, including an issue that resulted in some patches that may have released the active ingredient at a faster rate than the rate provided in the product specifications. Any similar recall, withdrawal or seizure in the future, particularly if they involve our own proprietary product candidates, could materially and adversely affect consumer confidence in our brands and lead to decreased demand for our products. In addition, a recall, withdrawal or seizure of any of our products would require significant management attention, would likely result in substantial and unexpected expenditures, and would harm our business, financial condition, and results of operations.

If we or our partners are unable to achieve and maintain adequate levels of coverage and reimbursement for our products, or any future products we may seek to commercialize, their commercial success may be severely hindered.

For our products that are available only by prescription, successful sales by our partners depend on the availability of adequate coverage and reimbursement from third‑party payors. Patients who are prescribed medicine for the treatment of their conditions generally rely on third‑party payors to reimburse all or part of the costs associated with their prescription drugs. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and private third‑party payors is critical to new product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Our proprietary self-funded drug development programs incorporate active drug ingredients that have been previously approved and marketed and that generally are available as less expensive generic products in non-transdermal dosage forms. If our products do not demonstrate superior efficacy profiles or other benefits compared to existing products or dosage forms, they may not qualify for coverage and reimbursement. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate or may require co‑payments or co-insurance payments that patients find unacceptably high. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products.

In addition, the market for our products will depend significantly on access to third‑party payors’ drug formularies, which are the lists of medications for which third‑party payors provide coverage and reimbursement. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies. Also, third‑party payors may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent or other alternative is available.

Third‑party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the United States, no uniform policy of coverage and reimbursement for drug products exists among third‑party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time‑consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions both in the United States and in international markets. Third‑party coverage and reimbursement for our products or any of our product candidates for which we may receive regulatory approval may not be available or adequate in either the United States or international markets, which could harm our business, results of operations, financial condition and prospects.

Most of our partners depend on wholesale pharmaceutical distributors for retail distribution of our products and, if our partners lose any of their significant wholesale pharmaceutical distributors, our business could be harmed.

The majority of our partners’ pharmaceutical sales are to wholesale pharmaceutical distributors who, in turn, sell the products to pharmacies, hospitals and other customers. The loss of any of these wholesale pharmaceutical distributors’ accounts or a material reduction in their purchases could have a material adverse effect on our business, results of operations, financial condition and prospects. In addition, these wholesale customers comprise a significant part of the distribution network for pharmaceutical products in the United States. This distribution network has undergone, and may continue to undergo, significant consolidation marked by mergers and acquisitions. As a result, a small number of large wholesale distributors control a significant share of the market. Consolidation of drug wholesalers has increased, and may continue to increase, competitive and pricing pressures on pharmaceutical products. We cannot assure you that we or our partners can manage these pricing pressures or that wholesaler purchases will not fluctuate unexpectedly from period to period.

Our results of operations may be adversely affected by demand fluctuations outside our ability to control or influence.

In general, our marketing partners are required to provide us with 12‑month rolling forecasts of their demand on a quarterly basis, and are also required to place firm purchase orders with us based on the near‑term portion of those

forecasts. If wholesaler or market demand for these products is lower than forecasted, our marketing partners or their wholesaler customers may accumulate excess inventory. Additionally, our marketing partners may price our products at levels that result in lost contract sales to their wholesaler customers. If such conditions persist, our marketing partners may sharply reduce subsequent purchase orders for a sustained period of time until such excess inventory is consumed, if ever. Significant and unplanned reductions in our manufacturing orders have occurred in the past and our results of operations were harmed. If such reductions occur again in the future, our revenues will be negatively impacted, we will lose our economies of scale, and our revenues may be insufficient to fully absorb our overhead costs, which could result in larger net losses. Conversely, if our marketing partners experience significantly increased demand, we may not be able to manufacture such unplanned increases in a timely manner, especially following prolonged periods of reduced demand. As we have no control over these factors, including our marketing partners’ decisions on pricing, our purchase orders could fluctuate significantly from quarter to quarter, and the results of our operations could fluctuate accordingly.

Our MicroCor technology has not been incorporated into a therapeutic commercial product and is still at a relatively early stage of development.

Our MicroCor technology, utilizing proprietary microneedle arrays, has not been incorporated into a therapeutic commercial product and is still at a relatively early stage of development. We use this technology in several of our therapeutic candidates. Although we have conducted clinical trials for our product candidate MicroCor hPTH(1‑34), additional studies are required for this product candidate and there is no guarantee that future clinical trials will prove the technology is effective or does not have harmful side effects. Any failures or setbacks in utilizing our MicroCor technology, including adverse effects resulting from the use of this technology in humans, could have a detrimental impact on our internal product candidate pipeline and our ability to enter into new corporate collaborations regarding this technology, which would harm our business and financial position. As of yet, no pharmaceutical product incorporating microneedle technology has been approved by the FDA for commercial sale.

In addition, our MicroCor product candidates have been manufactured in small quantities for preclinical studies and Phase 1 and Phase 2a clinical trials. In the future, preparation for later stage clinical trials and potential commercialization would require us to take steps to increase the scale of production of MicroCor product candidates. In order to conduct larger or late‑stage scale clinical trials for a MicroCor product candidate and supply sufficient commercial quantities of the resulting drug product and its components, if that product candidate is approved for sale, we will need to manufacture it in larger quantities. We may not be able to increase successfully the manufacturing capacity for any of such product candidates in a timely or cost‑effective manner or at all. Significant scale‑up of manufacturing may require additional processes, technologies and validation studies, which are costly and could require additional sources of funding, may not be successful and may not be approved by the FDA. In addition, quality issues may arise during those scale‑up activities because of the inherent properties of a product candidate itself or of a product candidate in combination with other components added during the manufacturing and packaging process, or during shipping and storage of the finished product or active pharmaceutical ingredients. If we are unable to successfully scale‑up the manufacture of any of our MicroCor product candidates in sufficient quality and quantity, the development of that product candidate and regulatory approval or commercial launch for any resulting drug products may be delayed, or there may be a shortage in supply, either of which could significantly harm our business.

If we are not able to establish collaborations, we may have to alter our development and commercialization plans.

The development and potential commercialization of our product candidates will require substantial additional cash to fund expenses. For some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of those product candidates. For example, although we have self-funded Phase 1 and Phase 2a clinical trials for MicroCor hPTH(1‑34), in order to continue the development and commercialization of this product candidate, we are currently seeking a partner or partners who will fund further development of MicroCor hPTH(1-34).

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and experience, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA or other

regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available for collaboration and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under future license agreements from entering into agreements on certain terms with potential collaborators. Collaborations are complex and time‑consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms or at all. If we are unable to do so, we may have to curtail the development of one or more product candidates, reduce or delay one or more of our development programs, delay potential commercialization, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenues.

The results and anticipated timelines of our clinical trials are uncertain and may not support continued development of a product candidate, which would adversely affect our prospects for future revenue growth.

We are required to demonstrate the safety and efficacy of products that we develop for each intended use through extensive preclinical studies and clinical trials. The results from preclinical and early clinical studies do not always accurately predict results in later, large-scale clinical trials. Even successfully-completed large-scale clinical trials may not result in marketable products. If any of our product candidates fail to achieve the primary endpoint in clinical trials, if safety issues arise or if the results from our clinical trials are otherwise inadequate to support regulatory approval of our product candidates, commercialization of that product candidate could be delayed or halted. In addition, we may face challenges in clinical trial protocol design.

If the clinical trials for any of the product candidates in our pipeline are delayed or terminated, our prospects for future revenue growth would be adversely impacted. For example, we face numerous risks and uncertainties with our product candidates, including our ability to enroll patients in clinical trials, the possibility of unfavorable results of our clinical trials, the need to modify or delay our clinical trials or to perform additional trials and the risk of failing to obtain FDA and other regulatory body approvals. As a result, our product candidates may never be successfully commercialized. Further, we may make a strategic decision to discontinue development of product candidates if, for example, we believe commercialization will be difficult relative to other opportunities in our pipeline. If these programs and others in our pipeline cannot be completed on a timely basis or at all, then our prospects for future revenue growth may be adversely impacted. In addition, clinical trials involving our commercial products could raise new safety issues for our existing products, which could in turn decrease our revenues and harm our business.

Due to our reliance and our partners reliance on third-party contract research organizations to conduct our clinical trials, we are unable to directly control or monitor the timing, conduct, expense and quality of our clinical trials, which could adversely affect our clinical data and results and related regulatory approvals.

We and our partners extensively outsource our clinical trial activities and usually perform only a small portion of the start-up activities in-house. We and our partners rely on independent third-party contract research organizations (“CROs”) to perform most of our clinical studies, including document preparation, site identification, screening and preparation, pre-study visits, training, program management and bioanalytical analysis. Many important aspects of the services performed for us and our partners by the CROs are out of our direct control. If there is any dispute or disruption in our or our partners’ relationship with our CROs, clinical trials may be delayed. Moreover, in our regulatory submissions, we and our partners rely on the quality and validity of the clinical work performed by third-party CROs. If any of these CROs’ processes, methodologies or results were determined to be invalid or inadequate, our or our partners’ own clinical data and results and related regulatory approvals could be adversely affected. Furthermore, we rely on

timely and accurate activity reporting from our CROs to form the principal basis of our clinical trial expense accruals. If our CROs inaccurately or incompletely report activities that drive costs, or if such reports are not delivered in a timely manner, our clinical trial expense accruals may be inaccurate, and could materially under or over state our clinical trial expenses in any given period.

We will need to further increase the size and complexity of our organization in the future, and we may experience difficulties in executing our growth strategy and managing any growth.

Our management, personnel, systems and facilities currently in place may not be adequate to support our business plan and future growth. We will need to further expand our scientific, sales and marketing, managerial, operational, financial and other resources to support our planned research, development and commercialization activities.

Our need to manage our operations, growth and various projects effectively requires that we:

In addition, historically, we have utilized and continue to utilize the services of part‑time outside consultants to perform a number of tasks for us, including tasks related to preclinical and clinical testing. Our growth strategy may also entail expanding our use of consultants to implement these and other tasks going forward. Because we rely on consultants for certain functions of our business, we will need to be able to effectively manage these consultants to ensure that they successfully carry out their contractual obligations and meet expected deadlines. There can be no assurance that we will be able to manage our existing consultants or find other competent outside consultants, as needed, on economically reasonable terms, or at all. If we are not able to effectively expand our organization by hiring new employees and expanding our use of consultants, we might be unable to implement successfully the tasks necessary to execute effectively on our planned research, development and commercialization activities and, accordingly, might not achieve our research, development and commercialization goals.

If we fail to attract and retain management and other key personnel, we may be unable to continue to successfully commercialize our products, develop our product candidates or otherwise implement our business plan.

Our ability to compete in the highly competitive pharmaceuticals industry depends upon our ability to attract and retain highly qualified managerial, scientific, medical and other personnel. We are highly dependent on our management and scientific personnel, including our President and Chief Executive Officer, Peter Staple, our Chief Financial Officer, Robert Breuil, our Chief Technology Officer and Vice President, Research and Development,

Parminder Singh and our other executive officers. The loss of the services of any of these individuals could impede, delay or prevent the continuing commercialization of our products and the development of our product candidates and could negatively impact our ability to successfully implement our business plan. If we lose the services of any of these individuals, we might not be able to find suitable replacements on a timely basis or at all, and our business could be harmed as a result. We do not maintain “key man” insurance policies on the lives of these individuals or the lives of any of our other employees. We employ all of our executive officers and key personnel on an at‑will basis and their employment can be terminated by us or them at any time, for any reason and without notice. In order to retain valuable employees at our company, in addition to salary and cash incentives, we may provide stock options and restricted stock unit awards that vest over time. The value to employees of stock options and restricted stock unit awards that vest over time will be significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract offers from other companies.

We might not be able to attract or retain qualified management and other key personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Francisco Bay area where we are headquartered. We could have difficulty attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention efforts. We do not currently have a chief medical officer, and we cannot assure you that, if we require such a position to be filled, we will be able to hire a qualified candidate for this position. Many of the other pharmaceutical companies with whom we compete for qualified personnel have greater financial and other resources, different risk profiles and longer histories in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will harm our ability to implement our business strategy and achieve our business objectives.

In addition, we have scientific and clinical advisors who assist us in formulating our development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

We provided written notice to terminate the lease for a new building in Fremont, California, which may lead to additional cost and expense and could disrupt our operations, including as a result of the related litigation.

On February 12, 2016, we entered into a lease agreement for facilities in Fremont, California, which was intended to replace our current headquarters in Menlo Park, California.  On July 29, 2016, we exercised our termination right under Section 4.2 of the lease by providing the landlord with written notice to terminate the lease agreement effective immediately because the underlying premises were not delivered to us in accordance with the terms of the lease agreement.  The landlord objected to the written notice of termination and, on September 23, 2016, the landlord filed a complaint against us in the Superior Court of California, County of Alameda, LBA Realty Fund III-Company VII, LLC vs. Corium International, Inc., alleging breach of contract with respect to the lease agreement. The complaint alleges that we breached the lease when we provided written notice to the landlord to terminate, and seeks damages in excess of $10.0 million as well as declaratory relief. On or about November 16, 2016, we filed our answer generally denying the allegations and setting forth our defenses.  At the same time, we also filed a cross-complaint seeking compensatory damages, among other relief, for the landlord’s material breaches with respect to the lease agreement.  An initial case management conference is scheduled for February 8, 2017.  The parties have not yet exchanged discovery.  No trial date has been set.

Notwithstanding the termination of the lease agreement and the fact that the landlord is obligated to reimburse us for certain costs, we expect to incur additional costs, which may have an adverse impact on our cash and results of operations. In addition, the pending litigation relating to the lease and its termination may be costly, may be disruptive to those involved in the litigation and our operations generally, and could have a negative impact on our financial results and condition especially if the litigation is protracted or if the outcome is adverse to us.

We may engage in strategic transactions that could impact our liquidity, increase our expenses and present significant distractions to our management.

From time to time we may consider strategic transactions, such as acquisitions of companies, asset purchases and out‑licensing or in‑licensing of products, product candidates or technologies. Additional potential transactions that we may consider include a variety of different business arrangements, including spin‑offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any such transaction may require us to incur non‑recurring or other charges, may increase our near and long‑term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our operations and financial results. For example, these transactions entail numerous potential operational and financial risks, including:

Accordingly, there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, and any transaction that we do complete could harm our business, results of operations, financial condition and prospects. We have no current plan, commitment or obligation to enter into any transaction described above.

Our business involves the use of hazardous materials and we and our third‑party suppliers must comply with environmental laws and regulations, which can be expensive and restrict how we do business.

Our research and development activities and our manufacturing activities involve the controlled storage, use and disposal of hazardous materials owned by us, including the components of our products and product candidates and other hazardous compounds. We are subject to laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. In some cases, these hazardous materials and various wastes resulting from their use are stored at our facilities pending use and disposal and we dispose of certain materials directly through incineration. We cannot completely eliminate the risk of contamination, which could cause an interruption of our commercialization efforts, research and development efforts and business operations, injury to our employees and others, environmental damage resulting in costly clean‑up and liabilities under applicable laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. Although we believe that the safety procedures we utilize for handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, we cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damages and such liability could exceed our resources. We do not currently carry biological or hazardous waste insurance coverage and our property and

casualty and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination.

Our employees, partners, independent contractors, principal investigators, consultants, vendors and contract research organizations may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, partners, independent contractors, principal investigators, consultants, vendors and CROs may engage in fraudulent or other illegal activity. Misconduct by these employees could include intentional, reckless and/or negligent conduct or unauthorized activity that violates: (1) FDA regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA; (2) manufacturing standards; (3) federal and state healthcare fraud and abuse laws and regulations; or (4) laws that require the true, complete and accurate reporting of financial information or data. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials, or illegal misappropriation of drug product, which could result in regulatory sanctions and serious harm to our reputation. We have dismissed employees in the past for improper handling and theft of our product components, and although we reported their actions to all relevant authorities, any similar incidents or any other conduct that leads to an employee receiving an FDA debarment could result in a loss of business from our partners and severe reputational harm. We have adopted a code of business conduct and ethics, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

We may be adversely affected by natural disasters or other events that disrupt our business operations, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate headquarters are located in Menlo Park, California, near major earthquake and fire zones. Our manufacturing facilities are in Grand Rapids, Michigan, where other natural disasters or similar events, like blizzards, tornadoes, fires or explosions or large‑scale accidents or power outages, could severely disrupt our operations, and have a material adverse effect on our business, results of operations, financial condition and prospects. If a disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters or our Grand Rapids facility, that damaged critical infrastructure, such as enterprise financial systems or manufacturing resource planning and enterprise quality systems, or that otherwise disrupted operations at either location, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time.

Our business and operations would suffer in the event of failures in our internal computer systems.

Despite the implementation of security measures, our internal computer systems and those of our current and any future partners, contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, attacks by computer hackers, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our manufacturing activities, development programs and our business operations. For example, the loss of manufacturing records or clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability or damage to our reputation, and the further commercialization and development of our products and product candidates could be delayed.

In connection with the reporting of our financial condition and results of operations, we are required to make estimates and judgments which involve uncertainties, and any significant differences between our estimates and actual results could have an adverse impact on our financial position, results of operations and cash flows.

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. For example, we estimate annual market revenues based on patient prescriptions using an analysis of third‑party information and third‑party market research data. If this third‑party data underestimates or overestimates actual revenues for a given period, adjustments to revenues may be necessary in future periods. Any significant differences between our actual results and our estimates and assumptions could negatively impact our financial position, results of operations and cash flows.

Changes in accounting standards and their interpretations could adversely affect our operating results.

U.S. GAAP are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the American Institute of Certified Public Accountants, the SEC, and various other bodies that promulgate and interpret appropriate accounting principles. These principles and related implementation guidelines and interpretations can be highly complex and involve subjective judgments. A change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.

Risks Related to Our Financial Position and Capital Requirements

We have had significant and increasing operating expenses and may require additional funding to continue as a going concern.

We believe that our existing cash and cash equivalents will not be sufficient to fund operations as currently planned through the next 12 months, which raises substantial doubt about our ability to continue as a going concern. We have based this belief on assumptions and estimates that may prove to be wrong, and we could spend our available financial resources less or more rapidly than currently expected. We will continue to require additional sources of cash to develop product candidates and to fund development and commercialization operations.  We intend to seek additional capital through equity and/or debt financings, collaborative or other funding arrangements with partners, or through other sources of financing. In the event that additional financing is required from outside sources, we may not be able to raise such financing on acceptable terms or at all. If we are unable to raise additional capital when required or on acceptable terms, we may be required to significantly delay, scale back or discontinue one or more of the product development programs or commercialization efforts or other aspects of our business plans, and our business, operating results and financial condition would be adversely affected.

We are currently in compliance with the covenants under our term loan agreement with CRG based on our current forecast estimates and expectations. However, we anticipate that our current cash and cash equivalent balances will not be sufficient to maintain compliance with the minimum liquidity financial covenant through fiscal 2017, or beyond. Failure to meet this covenant would be considered an event of default on our debt obligation, and could result in the acceleration of our existing indebtedness, causing the outstanding principal of approximately $51.1 million, plus penalties, to be immediately due and payable to CRG. We do not currently have sufficient cash and cash equivalents to repay all of the outstanding debt in full if repayment of such debt were accelerated. Due to these uncertainties, there is substantial doubt about our ability to continue as a going concern.

The amount and timing of our future funding requirements will depend on many factors, including, but not limited to:

We cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that we raise additional capital by issuing equity securities or convertible debt, your ownership will be diluted. Any future debt financing into which we enter may impose upon us covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, redeem our stock, make certain investments and engage in certain merger, consolidation or asset sale transactions.

If we are unable to raise additional capital when required or on acceptable terms, we may be required to significantly delay, scale back or discontinue one or more of our product development programs or commercialization efforts, or other aspects of our business plan. We also may be required to relinquish, license or otherwise dispose of rights to products or product candidates that we would otherwise seek to commercialize or develop ourselves on terms that are less favorable than might otherwise be available. In addition, our ability to achieve profitability or to respond to competitive pressures would be significantly limited.

Our independent registered public accounting firm has concurred with our determination that there is substantial doubt about our ability to continue as a going concern and we may be unable to remain a going concern absent additional financing.

We have incurred significant operating and net losses since our inception and expect to continue to incur net operating losses for at least the next several years. Without additional sources of capital, these conditions raise substantial doubt about our ability to continue as a going concern, which means that without additional external funding, we may be unable to continue operations for the foreseeable future or realize assets and discharge liabilities in the ordinary course of operations. As a result, our independent registered public accounting firm included an explanatory

paragraph with respect to this uncertainty in its report that is included with our financial statements in this Annual Report on Form 10-K. Such an opinion may materially and adversely affect the price per share of our common stock and may otherwise limit our ability to raise additional funds through the issuance of debt or equity securities or otherwise. Further, the perception that we may be unable to continue as a going concern may impede our ability to raise additional funds or operate our business due to concerns with respect to our ability to discharge our contractual obligations.

We have prepared our financial statements on a going concern basis, which contemplates that we will be able to realize our assets and discharge our liabilities and commitments in the ordinary course of business. Our financial statements included with this Annual Report on Form 10-K do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty. Without additional funds, however, we may be unable to continue as a viable entity, in which case our stockholders may lose all or some of their investment in us.

Our level of indebtedness could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry and prevent us from meeting our obligations.

As of September 30, 2016, the amount of our total long-term debt was approximately $51.6 million, which is primarily pursuant to our term loan agreement with CRG, formerly Capital Royalty. In November 2014, we amended our term loan agreement with CRG to increase the outstanding loan principal amount to $45.0 million (excluding payment-in-kind, (“PIK”) notes), extend the maturity date to June 30, 2019, and extend the quarterly interest‑only payments through June 30, 2018, with principal and interest payments due in four quarterly installments beginning September 30, 2018. On December 4, 2014, we borrowed the remaining $10.0 million of principal provided for in the amended agreement and no principal funds remain available to us for borrowing under the CRG term loan agreement. On November 11, 2015, the term loan agreement was further amended to modify the financial covenants with respect to the minimum annual revenues requirement (beginning with the 12 months ending June 30, 2016) and minimum liquidity requirement, and, on December 19, 2016, the term loan agreement was amended again to modify the financial covenants with respect to the minimum annual revenues requirement (for the 12 months ending June 30, 2017), all as described in further detail in “—The terms of our term loan agreement place restrictions on our operating and financial flexibility.”   

Our outstanding debt and related debt service obligations could have important adverse consequences to us, including:

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay product development, sales and marketing, capital and other expenditures, sell assets, seek additional capital or restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

The terms of our term loan agreement place restrictions on our operating and financial flexibility.

During any such times when we have outstanding borrowings under the term loan agreement with CRG, we will be required to maintain certain deposits and minimum balances as well as be prohibited from engaging in significant business transactions without the prior consent of CRG, including a change of control or the acquisition by us of another company, or engaging in new business activities which are substantially different from our current business activities. These restrictions could significantly limit our ability to respond to changes in our business or competitive activities or take advantage of business opportunities that may create value for our stockholders. In addition, under the term loan agreement with CRG, we are subject to covenants relating to our business, including, but not limited to covenants relating to the achievement of minimum annual revenues and minimum liquidity. For the twelve (12) months ended June 30, 2017, the minimum annual revenues required by our covenant are $25 million, and the minimum liquidity covenant throughout the term of the loan requires us to maintain a cash balance in excess of $10 million, provided, however, that our cash balance may decrease below $10 million for no more than five (5) non-consecutive business days during any quarter. The failure to meet either of these covenants is considered an event of default under the term loan agreement. We are also required to pay a prepayment penalty if we choose to repay the principal prior to maturity or upon other specified events, including an event of default or a change of control. In the event of a default under this arrangement, all of our repayment obligations may be accelerated in full. In the event that we do not have sufficient capital to repay the amounts then owed, we may be required to renegotiate such arrangements on terms less favorable to us, pursue strategic alternatives, including sale of our company or our significant assets, or to cease operations. Furthermore, if we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

Our ability to utilize our net operating loss carryforwards, or NOLs, and research and development income tax credit carryforwards may be limited.

As of September 30, 2016, we had net operating loss carry forwards (“NOLs”) for federal and state income tax purposes of $137.4 million and $21.7 million, respectively. If not utilized, these NOLs will expire beginning in 2026 and 2017 for federal and state income purposes, respectively. Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre‑change NOLs, and other pre‑change tax attributes (such as research tax credits) to offset its post‑change income may be limited. We believe that, with our initial public offering (the “IPO”) and other transactions that have occurred over the past three years, we may have triggered an “ownership change” limitation. We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre‑change NOLs to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or our guidance.

Our quarterly and annual operating results may fluctuate significantly in the future, which makes it difficult for us to predict our future operating results. From time to time, we enter into collaboration agreements with other companies that include development funding and significant upfront and milestone payments, and we expect that amounts earned from our collaboration agreements will continue to be an important source of our revenues. Accordingly, our revenues will depend on development funding and the achievement of development and clinical milestones under our existing collaboration arrangements, as well as any potential future collaboration and license agreements and sales of our products, if approved. These upfront and milestone payments may vary significantly from period to period and any such variance could cause a significant fluctuation in our operating results from one period to the next. For example, our product revenues from Clonidine TDS in fiscal 2013 were higher than historic levels, primarily as a result of Teva’s increased market share resulting from a major competitor’s diminished ability to supply its product for seven months during the year. Revenues returned to historic levels in fiscal 2014. Product revenues in fiscal 2015 related to Clonidine TDS declined compared to fiscal 2014 due to an additional competitor entering the market in the second half of fiscal 2014, which adversely impacted Teva’s market share and pricing.  Fewer units sold or decreased unit pricing of Clonidine TDS directly reduces our profit sharing revenues. In connection with Teva’s

acquisition of the generic business of Allergan, it divested the Clonidine TDS product to Mayne in August 2016. If Mayne is less effective in its commercialization of this product than Teva, it may result in a loss of market share or reduced pricing, which could impact our revenues for this product for fiscal 2017 and beyond. In addition, product revenues related to Fentanyl TDS declined in fiscal 2016 compared to fiscal 2015 as a result of the amended terms of our agreements with Par and the continued impact of increased competition from other generic companies. We expect that our product revenues from Fentanyl TDS in fiscal 2017 will be lower than fiscal 2016 as a result of the continued impact of increased competition. Furthermore, we measure compensation cost for stock‑based awards made to employees at the grant date of the award, based on the fair market value of the award as determined by our board of directors, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing these awards change over time, including our underlying stock price and stock price volatility, the magnitude of the expense that we must recognize may vary significantly. Finally, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including the following:

Our results of operations and liquidity needs could be materially negatively affected by market fluctuations and economic downturn.

Our results of operations and liquidity could be materially negatively affected by economic conditions generally, both in the United States and elsewhere around the world. Domestic and international equity and debt markets have experienced and may continue to experience heightened volatility and turmoil based on domestic and international economic conditions and concerns. In the event these economic conditions and concerns continue or worsen and the markets continue to remain volatile, our results of operations and liquidity could be adversely affected by those factors in many ways, including making it more difficult for us to raise funds if necessary, and our stock price may decline. Additionally, although we market our products primarily in the United States, our partners have extensive global operations, indirectly exposing us to risk.

Risks Related to Regulation of our Products and Product Candidates

Our currently marketed products, and any of our product candidates that we or our partners commercialize, will be subject to ongoing and continued regulatory review, which may result in significant expense and limit our or our partners’ ability to commercialize such products.

Even after we achieve U.S. regulatory approval for a product, or after we or our partners commercialize an FDA‑regulated product that does not require premarket approval (such as our consumer teeth whitening products), we will be subject to continued regulatory review and compliance obligations. For example, with respect to our drug products, the FDA may impose significant restrictions on the approved indicated uses for which the product may be

marketed or on the conditions of approval. A drug product’s approval may contain requirements for potentially costly post‑approval studies and surveillance, including Phase 4 clinical trials, to monitor the safety and efficacy of the product. We will also be subject to ongoing FDA obligations and continued regulatory review with respect to the manufacturing, processing, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for our products. These requirements include submissions of safety and other post‑marketing information and reports, registration, as well as continued compliance with current Good Manufacturing Practice (“cGMP”) requirements, which are regulations addressing the proper design, monitoring, and control of manufacturing processes and facilities, and with the FDA’s Good Clinical Practice (“GCP”) and the FDA’s Good Laboratory Practice (“GLP”) requirements, which are regulations and guidelines enforced by the FDA for all of our products in clinical and pre‑clinical development, and for any clinical trials that we conduct post‑approval. To the extent that a product is approved for sale in other countries, we may be subject to similar restrictions and requirements imposed by laws and government regulators in those countries.

In the case of Fentanyl TDS and any of our product candidates containing controlled substances, we will also be subject to ongoing DEA regulatory obligations, including, among other things, annual registration renewal, security, recordkeeping, theft and loss reporting, periodic inspection and annual quota allotments for the raw material for commercial production of our products. In addition, manufacturers of drug products and their facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP regulations, including the Quality System Regulation requirements for medical device components of our products or similar requirements, if applicable. If we or a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where, or processes by which, the product is manufactured, a regulatory agency may impose restrictions on that product or us, including requesting that we initiate a product recall, or requiring notice to physicians, withdrawal of the product from the market or suspension of manufacturing.

Since 2010, the FDA has inspected our facility several times and issued Forms 483 with its observations. The FDA has closed out each of these inspections and issued an Establishment Inspection Report in each case.

If we, our products or product candidates or the manufacturing facilities for our products or product candidates fail to comply with applicable regulatory requirements, a regulatory agency may:

In addition, our or our partners’ product labeling, advertising and promotion are subject to regulatory requirements and continuing regulatory review. The FDA strictly regulates the promotional claims that may be made about prescription drug products. In particular, a drug product may not be promoted for uses that are not approved by the FDA as reflected in the product’s approved labeling, although the FDA does not regulate the prescribing practices of physicians. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off‑label uses, and a company that is found to have improperly promoted off‑label uses may be subject to significant liability, including substantial monetary penalties and criminal prosecution.

The FDA’s regulations, policies or guidance may change and new or additional statutes or government regulations may be enacted that could prevent or delay regulatory approval of our product candidates or further restrict or regulate post‑approval activities. 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 achieve and maintain regulatory compliance, we may not be permitted to manufacture or market our products, which would adversely affect our ability to generate revenues and achieve or maintain profitability.

Some of our products or product candidates contain controlled substances, the making, use, sale, importation and distribution of which are subject to regulation by state, federal and foreign law enforcement and other regulatory agencies.

Fentanyl TDS and certain of our other drug product candidates contain active ingredients which are classified as controlled substances, which are subject to state, federal and foreign laws and regulations regarding their manufacture, use, sale, importation, exportation and distribution. Controlled substances are regulated under the CSA, and the regulations of the DEA. The DEA regulates controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no established medicinal use and may not be marketed or sold in the United States. A pharmaceutical product may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest relative risk of abuse among such substances. Fentanyl TDS is regulated by the DEA as a Schedule II controlled substance.

Various states also independently regulate controlled substances. Though state controlled substances laws often mirror federal law, because the states are separate jurisdictions, they may separately schedule drugs as well. While some states automatically schedule a drug when the DEA does so, in other states there must be rulemaking or a legislative action. Adverse scheduling could impair the commercial attractiveness of such product. We or our collaborators must also obtain separate state registrations in order to be able to obtain, handle and distribute controlled substances for clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to enforcement and sanctions from the states in addition to those from the DEA or otherwise arising under federal law.

For our products or product candidates containing controlled substances, we and our partners, suppliers, contractors and distributors are required to obtain and maintain applicable registrations from state, federal and foreign law enforcement and regulatory agencies and comply with state, federal and foreign laws and regulations regarding the manufacture, use, sale, importation, exportation and distribution of controlled substances. These regulations are extensive and include regulations governing manufacturing, labeling, packaging, testing, dispensing, production and procurement quotas, record keeping, reporting, handling, shipment and disposal. These regulations increase the personnel needs and the expense associated with development and commercialization of drug candidates including controlled substances. Failure to obtain and maintain required registrations or comply with any applicable regulations could delay or preclude us from developing and commercializing our products containing controlled substances and subject us to enforcement action. In addition, because of their restrictive nature, these regulations could limit our commercialization of our pharmaceutical systems containing controlled substances. In particular, among other things, there is a risk that these regulations may interfere with the supply of the drugs used in our clinical trials, and in the future, our ability to produce and distribute our products in the volume needed to meet commercial demand. The DEA may seek civil penalties, refuse to renew necessary registrations or initiate proceedings to revoke those registrations. In some circumstances, violations could lead to criminal proceedings. Because of their restrictive nature, these regulations could limit commercialization of any of our product candidates that are classified as controlled substances.

In addition to the level of commercial success of our approved products, our future growth is also dependent on our ability to successfully develop a pipeline of product candidates, and we cannot give any assurance that any of our product candidates will receive regulatory approval or that any approved products will be successfully commercialized.

Our long‑term growth will be limited unless we successfully develop a pipeline of additional product candidates. We do not have internal new drug discovery capabilities, and our primary focus is on developing improved transdermal drug delivery systems by reformulating FDA-approved drugs using our proprietary technologies.

Our near‑term revenue growth is dependent on the ability of our partner Agile to gain FDA approval of the Twirla transdermal contraceptive patch and to bring this product to market. Our collaboration partner Agile has conducted Phase 3 clinical studies and filed an NDA with the FDA for Twirla in April 2012. The FDA issued a Complete Response Letter in February 2013 identifying certain issues, including a request for additional clinical data, which must be addressed before approval can be granted. In addition, in light of Mylan’s introduction of a generic version of the Ortho Evra contraceptive patch in April 2014, the Twirla product may face additional competition, assuming it is approved and commercialized. We cannot assure you that Agile will be able to obtain regulatory approval for the Twirla product, or successfully commercialize the product, which would limit our near‑term growth prospects, and would create uncertainty around the value and usefulness of our Twirla manufacturing facility and equipment.

We have one partnered product candidate that is the subject of a pending ANDA submitted by our partner to the FDA, and several product candidates in clinical development. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and in foreign countries. Obtaining approval of an NDA or ANDA is a lengthy, expensive and uncertain process. The FDA also has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons.

For example, our product candidates could fail to receive regulatory approval for many reasons, including the following:

Any of our product candidates may fail to achieve their specified endpoints in clinical trials. Furthermore, product candidates may not be approved even if they achieve their specified endpoints in clinical trials. The FDA may disagree with the design of clinical trials and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for clinical trials. The FDA may also approve a product candidate for fewer or more limited indications than we or our partners request, or may grant approval

contingent on the performance of costly post‑approval clinical trials. In addition, the FDA may not approve the labeling claims that we or our partners believe are necessary or desirable for the successful commercialization of our product candidates.

If we are unable to expand our pipeline and obtain regulatory approval for our product candidates on the timelines we anticipate, we will not be able to execute our business strategy effectively and our ability to substantially grow our revenues will be limited, which would harm our long‑term business, results of operations, financial condition and prospects.

We manufacture our products internally and may be unable to manufacture them at acceptable cost levels, and we could encounter manufacturing failures that could impede or delay commercial production of our current products or our product candidates, if approved, or the preclinical and clinical development or regulatory approval of our product candidates.

Our ability to successfully launch and grow our products will require the ability to manufacture commercial quantities of our products at increasing scale and at acceptable cost levels while remaining in compliance with continuously evolving regulatory requirements. Any failure in our internal manufacturing operations, or inability to scale up, could cause us to be unable to meet the demand for our products and lose potential revenues, delay the preclinical and clinical development or regulatory approval of our product candidates, and harm our reputation. Our internal manufacturing operations may encounter difficulties involving, among other things, raw material supplies of sufficient quality and quantity, production yields, regulatory compliance, quality control and quality assurance, obtaining DEA quotas which allow us to produce in the quantities needed to execute on our business plan, and shortages of qualified personnel. Our ability to commercially supply our products, and regulatory approval of our product candidates, could be impeded, delayed, limited or denied if the FDA does not maintain the approval of our manufacturing processes and facilities. In addition, we have no experience producing our MicroCor system in commercial quantities. We have experienced product recalls in the past and we may encounter difficulties when we attempt to manufacture commercial quantities of our product candidates in the quantities needed for our preclinical studies or clinical trials. Such difficulties could result in commercial supply shortfalls of our products, delay in the commercial launch of any of our product candidates, if approved, delays in our preclinical studies, clinical trials and regulatory submissions, or the recall or withdrawal of our products from the market.

We must comply with cGMP requirements enforced by the FDA through its facilities inspection program and review of submitted technical information. In addition, we must obtain and maintain necessary DEA and state registrations, and must establish and maintain processes to assure compliance with DEA and state requirements governing, among other things, the storage, handling, security, recordkeeping and reporting for controlled substances. We must also apply for and receive a quota for fentanyl for our Fentanyl TDS product. Any failure to comply with these requirements may result in penalties, including fines and civil penalties, suspension of production, suspension or delay in product approvals, product seizure or recall, operating restrictions, criminal prosecutions, withdrawal of product approvals or severe reputational harm, any of which could adversely affect our business. If the safety of any product or product candidate or component is compromised due to a failure to adhere to applicable laws or for other reasons, we may not be able to successfully commercialize or obtain regulatory approval for the affected product or product candidate, and we may be held liable for injuries sustained as a result. Any of these factors could cause a delay or termination of commercialization, preclinical studies and clinical trials, regulatory submissions or approvals of our products or product candidates, entail higher costs or result in our being unable to effectively commercialize our approved products.

Clinical drug development for our product candidates is expensive, time consuming, uncertain and susceptible to change, delay or termination.

Clinical drug development for our product candidates is very expensive, time‑consuming and difficult to design and implement. Our product candidates are in varying stages of development ranging from pre‑clinical feasibility studies to registration. We estimate that clinical trials for these product candidates, if and when initiated, will continue for several years and may take significantly longer than expected to complete. In addition, we, our partners, the FDA, an

independent Institutional Review Board (an “IRB”) or other regulatory authorities, including state and local agencies, may suspend, delay or terminate our clinical trials at any time, for various reasons, including:

Generally, there is a high rate of failure for drug candidates proceeding through clinical trials. We or our partners may suffer significant setbacks in our clinical trials similar to the experience of a number of other companies in the pharmaceutical and biotechnology industries, even after receiving promising results in earlier trials. Further, even if we view the results of a clinical trial to be positive, the FDA or other regulatory authorities may disagree with our interpretation of the data. Even after the completion of Phase 3 or other pivotal clinical studies, we may have to address additional issues raised by the FDA in response to the NDA or ANDA filed by us or our partners, such as the issues with the Agile contraceptive patch. In the event that we or our partners abandon or are delayed in the clinical development efforts related to our product candidates, we may not be able to execute on our business plan effectively, we may not be able to become profitable, our reputation in the industry and in the investment community could be significantly damaged and our stock price could decrease significantly.

We have in the past relied and expect to continue to rely on third parties to conduct and oversee our clinical trials. If these third parties do not meet our deadlines or otherwise conduct the trials as required we may not be able to obtain regulatory approval for or commercialize our product candidates when expected or at all.

We have in the past relied and expect to continue to rely on third‑party CROs to conduct and oversee our clinical trials. For example, we contracted with a CRO in Australia to conduct the Phase 1 and Phase 2a clinical trials for our MicroCor hPTH(1‑34) and the Phase 1 clinical trials for our Corplex Donepezil and Corplex Memantine products.

We also rely upon various medical institutions, clinical investigators and contract laboratories to conduct our trials in accordance with our clinical protocols and all applicable regulatory requirements, including the FDA’s GCP regulations and state regulations governing the handling, storage, security and recordkeeping for controlled substances. These CROs and third parties play a significant role in the conduct of these trials and the subsequent collection and analysis of data from the clinical trials. We rely heavily on these parties for the execution of our clinical and preclinical studies, and control only certain aspects of their activities. We and our CROs and other third-party contractors are required to comply with GCP requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for products in clinical development. Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or other regulatory authority may require us to perform additional clinical trials before approving our or our partners’ marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials complies with GCP requirements. In addition, our clinical trials must generally be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

If any of our CROs or clinical trial sites terminate their involvement in one of our clinical trials for any reason, we may not be able to enter into arrangements with alternative CROs or clinical trial sites, or do so on commercially reasonable terms. In addition, if our relationship with clinical trial sites is terminated, we may experience the loss of follow‑up information on patients enrolled in our ongoing clinical trials unless we are able to transfer the care of those patients to another qualified clinical trial site. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be questioned by the FDA.

We have conducted and may in the future conduct clinical trials for our products or product candidates outside the United States and the FDA may not accept data from such trials.

We have conducted and may in the future choose to conduct one or more of our clinical trials outside the United States. For example, our CRO conducted the Phase 1 and Phase 2a clinical trials for our MicroCor hPTH(1‑34), and the Phase 1 trials for our Corplex Donepezil and Corplex Memantine products in Australia. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of such study data by the FDA is subject to certain conditions. For example, the study must be conducted in accordance with GCP requirements and the FDA must be able to validate the data from the study through an onsite inspection if it deems such inspection necessary. Where data from foreign clinical trials are intended to serve as the sole basis for marketing approval in the United States, the FDA

will not approve the application on the basis of foreign data alone unless those data are applicable to the U.S. population and U.S. medical practice; the studies were performed by clinical investigators of recognized competence; and the data is considered valid without the need for an on‑site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on‑site inspection or other appropriate means. In addition, such studies would be subject to the applicable local laws of the foreign jurisdictions where the studies are conducted. There can be no assurance the FDA will accept data from trials conducted outside of the United States. If the FDA does not accept any such data, it would likely result in the need for additional trials, which would be costly and time‑consuming and delay aspects of our business plan, including the development and commercial launch of any product candidates impacted by such a decision by the FDA.

If the FDA concludes that certain of our product candidates do not satisfy the requirements under Section 505(b)(2) of the Federal Food Drug and Cosmetics Act, or Section 505(b)(2), or if the requirements for such product candidates under Section 505(b)(2) are not as we expect, the approval pathway for those product candidates will likely take significantly longer, cost significantly more and entail significantly greater complications and risks than anticipated, and in either case may not be successful.

We and our collaboration partners are developing several proprietary product candidates, for which we and our partners intend to seek FDA approval through the Section 505(b)(2) regulatory pathway. The Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch‑Waxman Act, added Section 505(b)(2) to the Federal Food, Drug and Cosmetic Act. Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies that were not conducted by or for the applicant, and for which the applicant has not received a right of reference, which could expedite the development program for our product candidates by potentially decreasing the amount of clinical data that we or our partners would need to generate in order to obtain FDA approval. If the FDA does not allow us or our partners to pursue the Section 505(b)(2) regulatory pathway as anticipated, we or our partners may need to conduct additional clinical trials, provide additional data and information, and meet additional standards for regulatory approval. If this were to occur, the time and financial resources required to obtain FDA approval for these product candidates, and complications and risks associated with these product candidates, would likely substantially increase. Moreover, inability to pursue the Section 505(b)(2) regulatory pathway could result in new competitive products reaching the market more quickly than our product candidates, which would likely harm our competitive position and prospects. Even if we or our partners are allowed to pursue the Section 505(b)(2) regulatory pathway, we cannot assure you that our product candidates will receive the requisite approvals for commercialization.

In addition, notwithstanding the approval of a number of products by the FDA under Section 505(b)(2) over the last few years, certain competitors and others have objected to the FDA’s interpretation of Section 505(b)(2). If the FDA’s interpretation of Section 505(b)(2) is successfully challenged, the FDA may be required to change its 505(b)(2) policies and practices, which could delay or even prevent the FDA from approving any NDA that we or our partners submit under Section 505(b)(2). In addition, the pharmaceutical industry is highly competitive, and Section 505(b)(2) NDAs are subject to special requirements designed to protect the patent rights of sponsors of previously approved drugs that are referenced in a Section 505(b)(2) NDA. These requirements may give rise to patent litigation and mandatory delays in approval of our 505(b)(2) NDAs or our partners’ 505(b)(2) NDAs for up to 30 months depending on the outcome of any litigation. It is not uncommon for a manufacturer of an approved product to file a citizen petition with the FDA seeking to delay approval of, or impose additional approval requirements for, pending competing products. If successful, such petitions can significantly delay, or even prevent, the approval of the new product. However, even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while it considers and responds to the petition. In addition, even if we or our partners are able to utilize the Section 505(b)(2) regulatory pathway, there is no guarantee this would ultimately lead to faster product development or earlier approval.

Moreover, even if our product candidates are approved under Section 505(b)(2), the approval may be subject to limitations on the indicated uses for which the products may be marketed or to other conditions of approval, or may contain requirements for costly post‑marketing testing and surveillance to monitor the safety or efficacy of the products.

The FDA or foreign regulatory agencies will determine the regulatory pathway for our Alzheimer’s product candidates, Corplex Donepezil and Corplex Memantine, which could impact cost, timing and design of our clinical trials and marketing for these product candidates. 

There is no general FDA guidance on whether bioequivalence studies can be relied on for approval of a transdermal formulation under the Section 505(b)(2) regulatory pathway where the reference listed drug is an oral dosage form. It is possible that for drugs with a long half-life such as donepezil and memantine, as opposed to drugs with a short half-life, the plasma profile of the drug in the bloodstream for transdermal delivery will closely match the plasma profile seen with oral administration. For this reason, a bioequivalence regulatory strategy for approval of these products via the 505(b)(2) pathway may be possible. Following review of our pre-IND submissions for both Corplex Donepezil and Corplex Memantine, the FDA provided guidance on our development plans and registration pathway. The agency advised us that if we can adequately demonstrate bioequivalence between Corplex Donepezil and oral Aricept in our planned PK bioequivalence studies, additional clinical efficacy studies would not be required. Additionally, in August 2016, after review of our pre-IND submission of Corplex Memantine, the FDA concurred with our development plans for this product, including our proposal for pivotal studies based on the demonstration of PK bioequivalence between Corplex Memantine and oral Namenda XR® extended release capsules. If the FDA’s position on the regulatory pathway changes, or if our studies do not adequately support bioequivalence, more expensive and time-consuming studies may be needed, resulting in a longer clinical development timeline for these product candidates.

We have begun consultations with non-U.S. regulatory bodies, however we have not yet received formal feedback on the availability of the potential regulatory pathway outside the United States. If non-U.S. regulatory bodies determine that the bioequivalence pathway is not available, we will need to perform expensive, time-consuming efficacy studies to obtain regulatory approval in the relevant non-U.S. jurisdictions or we will not be able to commercialize our Alzheimer’s product candidates in these jurisdictions.

While the ability to obtain approval on the basis of a single pivotal pharmacokinetic bioequivalence study would save expense and time, this regulatory pathway will not allow us to market our products based on any potential advantages with respect to the rate of adverse events, such as gastrointestinal side effects, compared to the existing oral formulations of these products. We would need to perform additional, expensive, time-consuming studies in Alzheimer’s patients to generate data to demonstrate any of these potential benefits. We cannot guarantee that these additional studies, if performed, would demonstrate the superiority of our products. Further, if no benefit is shown from these studies, this could have an adverse impact on the competitive position of our products in the marketplace, which could harm our business, results of operations, financial condition and prospects.

The products that we make and develop may cause undesirable side effects or have other unexpected properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in post‑approval regulatory action.

Undesirable side effects caused by product candidates could cause us, or partners, or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or comparable foreign authorities. Results of clinical trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us, or our partners, to cease further development of or deny approval of product candidates for any or all targeted indications. The drug‑related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

The labeling for our Fentanyl TDS product, which is common to all fentanyl transdermal products, includes warnings of serious adverse events relating to abuse potential, respiratory depression and death, and risks relating to accidental exposure, drug interactions and exposure to heat.

Agile has conducted two Phase 3 clinical studies of the Twirla product. The safety population in these studies included patients who received at least one dose of either Twirla or a combination oral contraceptive. In the combined safety population of Agile’s Phase 3 trials, there were a total of 22 serious treatment emergent adverse effects, of which

16 were from the Twirla group, three (0.2%) of which were considered to be possibly related to the study drug, consisting of drug overdose with Benadryl, uncontrollable nausea and vomiting, and left subclavian deep vein thrombosis. Agile believes that Twirla will have a label consistent with all marketed hormonal contraceptive products, which include class labeling that warns of risks of certain serious conditions, including venous and arterial blood clot events, such as heart attacks, thromboembolism and stroke, as well as liver tumors, gallbladder disease, and hypertension. Regulatory authorities may require the inclusion of additional statements in the Twirla label, which may include a “black box” warning or contraindication. Based on guidance received from the FDA following the first two Phase 3 clinical trials, Agile is conducting an additional confirmatory Phase 3 clinical trial, and intends to submit the results of this additional trial to the FDA when complete.

Additionally, if we or others identify undesirable side effects, or other previously unknown problems, caused by our products, other products with the same or related active ingredients, or our or our partners’ product candidates, after obtaining U.S. regulatory approval, a number of potentially significant negative consequences could result, including:

Any of the above events resulting from undesirable side effects or other previously unknown problems could prevent us from achieving or maintaining market acceptance of the affected product and could substantially increase the costs of commercializing our products.

Healthcare reform measures could hinder or prevent the commercial success of our products and product candidates.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system that could affect our future revenues and profitability and the future revenues and profitability of our partners. Federal and state lawmakers regularly propose and, at times, enact legislation that results in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. For example, in March 2010, President Obama signed one of the most significant healthcare reform measures in decades, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or, collectively, the Affordable Care Act. It contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes and fraud and abuse measures, all of which will impact existing government healthcare programs and will result in the development of new programs. The Affordable Care Act, among other things, (i) increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to certain individuals enrolled in Medicaid managed care organizations, (ii) established annual fees on manufacturers of certain branded prescription

drugs and (iii) enacted a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point‑of‑sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. On August 2, 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers up to 2% per fiscal year, which went into effect on April 1, 2013. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, including hospitals and imaging centers.

Likewise, the annual Medicare Physician Fee Schedule update, which, until recently, was based on a target-setting formula system called the Sustainable Growth Rate (“SGR”), was adjusted to reflect the comparison of actual expenditures to target expenditures. Because one of the factors for calculating the SGR was linked to the growth in the U.S. gross domestic product (“GDP”), the SGR formula often resulted in a negative payment update when growth in Medicare beneficiaries’ use of services exceeded GDP growth.  Congress repeatedly intervened to delay the implementation of negative SGR payment updates.  For example, on April 1, 2014, with the enactment of the Protecting Access to Medicare Act of 2014, Congress prevented the 24 percent cut that was to occur by continuing the previously implemented 0.5 percent payment increase through December 31, 2014 and maintaining a zero percent payment update from January 1, 2015 through March 31, 2015.  However, on April 14, 2015, Congress passed the Medicare Access and CHIP Reauthorization Act of 2015, which was signed into law by President Obama on April 16, 2015.  This law repeals the SGR methodology from the physician payment formula, institutes a 0% update to the Medicare Physician Fee Schedule for the January 1 to July 1, 2015 period, a 0.5% payment update for July 2015 through the end of 2019, and a 0% payment update for 2020 through 2025.  For 2026 and subsequent years, the payment update will be either 0.75% or 0.25%, depending on which Alternate Payment Model the physician participates. In addition, there is increasing legislative attention to opioid abuse in the United States, including passage of the Comprehensive Addiction and Recovery Act of 2016 which, among other things, strengthens state prescription drug monitoring programs and expands educational efforts for certain populations.

More recently, while President-elect, Donald Trump has made statements suggesting he plans to seek repeal of all or portions of the 2010 Affordable Care Act, and has stated that he will ask Congress to replace the current legislation with new legislation. Once Mr. Trump becomes President, there is uncertainty with respect to the impact his Administration may have, if any, and any changes will likely take time to unfold, and could have an impact on coverage and reimbursement for healthcare items and services covered by plans that were authorized by the Affordable Care Act. However, we cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products once approved or additional pricing pressures, and may adversely affect our operating results.

We may also be subject to healthcare laws, regulation and enforcement and our failure to comply with those laws could adversely affect our business, operations and financial condition.

Even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third‑party payors, certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We could be subject to healthcare fraud and abuse and patient privacy regulation by both the federal government and the states in which we or our partners conduct our business. The laws and regulations that may affect our ability to operate include, without limitation:

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent health care reform legislation has strengthened these laws. For example, the Affordable Care Act, among other things, amends the intent requirement of the Federal Anti‑Kickback Statute and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. In addition, the Affordable Care Act provides that the government may assert that a claim including items or services resulting from a violation of the Federal Anti‑Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the laws described above or any other governmental laws or regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, the exclusion from participation in federal and state healthcare programs, imprisonment, or the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.

Risks Related to Our Intellectual Property

We may not be able to obtain and enforce patent rights or other intellectual property rights that cover our drug delivery systems, products, product candidates and technologies that are of sufficient breadth to prevent third parties from competing against us.

Our success with respect to our drug delivery systems and technologies will depend in part on our ability to obtain and maintain patent protection in both the United States and other countries, to preserve our trade secrets, and to prevent third parties from infringing upon our proprietary rights. Our ability to protect any of our approved products, product candidates or drug delivery systems from unauthorized or infringing use by third parties depends in substantial part on our ability to obtain and maintain valid and enforceable patents. Some of the drugs we use in our products have been approved for many years and therefore our ability to obtain any patent protection relating to the drug ingredients in our products may be limited.

Our patent portfolio related to our transdermal drug delivery systems and technologies includes patents and patent applications in the United States and foreign jurisdictions where we believe there is a significant market opportunity for our products. The covered technology and the scope of coverage vary from country to country. For those countries where we do not have granted patents, we may not have any ability to prevent the unauthorized use of our technologies. Any patents that we may obtain may be narrow in scope and thus easily circumvented by competitors. Further, in countries where we do not have granted patents, third parties may be able to make, use, or sell products identical to, or substantially similar to our products or product candidates.

Due to legal standards relating to patentability, validity, enforceability and claim scope of patents covering pharmaceutical inventions, our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. Accordingly, rights under any existing patents or any patents we might obtain or license may not provide us with sufficient protection for our products and product candidates to afford a commercial advantage against competitive products or processes, including those from branded and generic pharmaceutical companies. In addition, we cannot guarantee that any patents will issue from any pending or future patent applications owned by or licensed to us. Even if patents have issued or will issue, we cannot guarantee that the claims of these patents are or will be held valid or enforceable by the courts or will provide us with any significant protection against competitive products or otherwise be commercially valuable to us.

Our MicroCor technology is new even though patents relating to microneedle technology were first filed in the 1990s. Although we believe that the MicroCor technology includes certain inventions that are unique and not duplicative of any prior art and we have two issued U.S. patents covering our more recent developments in this technology, there can be no assurance that we will be successful in obtaining issued patents from the pending patent applications related to our MicroCor technology.

The laws of some foreign jurisdictions do not provide intellectual property rights to the same extent as in the United States and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property in foreign jurisdictions, our business prospects could be substantially harmed. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property.

Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third‑party patents.

The degree of future protection of our proprietary rights is uncertain. Patent protection may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

If we or our licensors fail to prosecute, maintain and enforce patent protection for our drug delivery technologies, products or product candidates, our ability to develop and commercialize our technologies, products or product candidates could be adversely affected and we might not be able to prevent competitors from making, using and selling competing technologies or products. This failure to properly protect the intellectual property rights relating to our technologies, products or product candidates could have a material adverse effect on our business, financial condition and results of operations. Moreover, our competitors may independently develop equivalent knowledge, methods and know‑how. Furthermore, in connection with our license agreement with P&G, we granted to P&G an exclusive license for certain fields of use to our Corplex technology and related know‑how. P&G may sublicense its rights under that license, including to another manufacturer, at any time, and we do not have any assurance that they will continue to use us as their development partner and manufacturer in the future.

Proprietary trade secrets and unpatented know‑how are also very important to our business. Although we have taken steps to protect our trade secrets and unpatented know‑how by entering into confidentiality agreements with third parties, and proprietary information and invention agreements with certain employees, consultants and advisors, third parties may still obtain this information or we may be unable to protect our rights. We also have limited control over the protection of trade secrets used by our licensees, partners and suppliers. There can be no assurance that binding agreements will not be breached, that we would have adequate remedies for any breach, or that our trade secrets and unpatented know‑how will not otherwise become known or be independently discovered by our competitors. If trade secrets are independently discovered, we would not be able to prevent their use. Enforcing a claim that a third party illegally obtained and is using our trade secrets or unpatented know‑how is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secret information.

If we or our partners are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.

Our commercial success depends upon our ability and the ability of our partners to develop, manufacture, market and sell our products and product candidates and use our proprietary technologies without infringing the proprietary rights of third parties. Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields relating to our products and product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that others may assert that our drug delivery systems, technologies, products or product candidates infringe their patent rights. Moreover, it is not always clear to industry

participants, including us, which patents cover various types of drugs, drug delivery systems or their methods of use. Thus, because of the large number of patents issued and patent applications filed in our fields, there may be a risk that third parties may allege they have patent rights encompassing our products, product candidates, technologies or methods.

In addition, there may be issued patents of third parties of which we are currently unaware, that are infringed or are alleged to be infringed by our products, product candidates or proprietary technologies. Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our own and in‑licensed issued patents or our pending applications. Our competitors may have filed, and may in the future file, patent applications covering our products, product candidates or technology similar to ours. Any such patent application may have priority over our own and in‑licensed patent applications or patents, which could further require us to obtain rights to issued patents covering such technologies. If another party has filed an U.S. patent application on inventions similar to those owned or in‑licensed to us, we or, in the case of in‑licensed technology, the licensor may have to participate, in the United States, in an interference proceeding to determine priority of invention.

A substantial portion of our partners’ products and product candidates are generic versions of pre‑existing brand name drugs and we may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights alleging that our partners’ products and/or product candidates and/or proprietary technologies infringe their intellectual property rights, including litigation resulting from filing under Paragraph IV of the Hatch‑Waxman Act. These lawsuits could claim that there are existing patent rights for such drug and this type of litigation can be costly and could adversely affect our results of operations and divert the attention of managerial and technical personnel. There is a risk that a court would decide that we or our commercialization partners are infringing the third party’s patents and would order us or our partners to stop the activities covered by the patents. In addition, there is a risk that a court will order us or our partners to pay the other party damages for having violated the other party’s patents. In addition to facing litigation risks directly, we have agreed to indemnify several of our partners against claims of infringement caused by our proprietary technologies, and we have entered or may enter into cost‑sharing agreements with some of our partners that could require us to pay some of the costs of patent litigation brought against those partners whether or not the alleged infringement is caused by our proprietary technologies. In certain instances, these cost‑sharing agreements could also require us to assume greater responsibility for infringement damages than would be assumed just on the basis of our technology.

There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries generally. To date, no litigation asserting infringement claims has ever been brought against us. If a third party claims that we or our partners infringe its intellectual property rights, we may face a number of issues, including, but not limited to:

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we or our partners can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could harm our ability to raise additional funds or otherwise adversely affect our business, results of operations, financial condition and prospects.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed to us alleged trade secrets of their other clients or former employers.

As is common in the biotechnology and pharmaceutical industry, certain of our employees were formerly employed by other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Moreover, we engage the services of consultants to assist us in the development of our products and product candidates, many of whom were previously employed at or may have previously been or are currently providing consulting services to, other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees and consultants or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or their former or current customers. Although we have no knowledge of any such claims being alleged to date, if such claims were to arise, litigation may be necessary to defend against any such claims. Even if we are successful in defending against any such claims, any such litigation could be protracted, expensive, a distraction to our management team, not viewed favorably by investors and other third parties, and may potentially result in an unfavorable outcome.

Risks Relating to Ownership of our Common Stock

Our principal stockholder has substantial control over our business, which may be disadvantageous to other stockholders.

Essex Woodlands Health Venture Fund VII, L.P., together with certain of its affiliates, which together we refer to as Essex Woodlands, collectively beneficially owns or controls approximately 42% of the voting power of our outstanding common stock. In addition, Ron Eastman, a Managing Director of Essex Woodlands, is a member of our board of directors. As a result of its ability to control a significant percentage of the voting power of our outstanding common stock, Essex Woodlands may have substantial control over matters requiring approval by our stockholders, including the election and removal of directors, amendments to our certificate of incorporation and bylaws, any proposed merger, consolidation or sale of all or substantially all of our assets and other corporate transactions. Essex Woodlands may have interests that are different from those of other stockholders. Moreover, this concentration of share ownership makes it difficult for other stockholders to replace directors and management without the consent of Essex Woodlands. In addition, this significant concentration of share ownership may adversely affect the price at which prospective buyers are willing to pay for our common stock because investors may perceive disadvantages in owning stock in a company with a single stockholder with this level of control.

Our common stock may be affected by limited trading volume and we expect that the price of our common stock will fluctuate substantially.

There has been a limited public market for our common stock and there can be no assurance that an active trading market for our common stock will develop. This could adversely affect your ability to sell our common stock in short time periods or possibly at all. The trading prices of the securities of pharmaceutical companies have been highly volatile. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

In addition, the stock markets, and in particular the Nasdaq Global Market, have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many pharmaceutical companies. Stock prices of many pharmaceutical companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were involved in securities litigation, we could incur substantial costs and our resources and the attention of management could be diverted from our business.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our

reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock. In addition, any future testing by us conducted in connection with Section 404 of the Sarbanes‑Oxley Act, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement.

We are required, pursuant to Section 404 of the Sarbanes‑Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting.  However, for as long as we are an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404. We could be an emerging growth company for up to five years following our IPO. An independent assessment of the effectiveness of our internal controls could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.

We have begun a process of transitioning from our previous financial tracking system to an updated enterprise resource planning system, but have not determined the timing for such a transition. Our current system has been in place since our founding and the transition will be costly and require new training and extensive changes to our system of our internal financial reporting. There is no guarantee that we will be able to transition smoothly and maintain effective internal controls over the reporting process during this transition.

If securities or industry analysts stop publishing research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

Future sales of our common stock or securities convertible into our common stock may depress our stock price.

Sales of a substantial number of shares of our common stock or securities convertible into our common stock in the public market, or the perception that these sales might occur may reduce the prevailing market price of our common stock and make it more difficult for you to sell your common stock at a time and price that you deem appropriate. In addition, any sales of securities by us or existing stockholders could have a material adverse effect on the market price of our common stock.

On December 30, 2015, we entered into a sales agreement with Cantor Fitzgerald & Co., as agent (“Cantor Fitzgerald”) pursuant to which we may offer and sell, from time to time through Cantor Fitzgerald, shares of its Common Stock with aggregate proceeds of up to $20.0 million.  As of September 30, 2016, all of the shares of Common Stock available for sale pursuant to the sales agreement remained available to be sold, subject to certain conditions as specified in the sales agreement, and sales of these shares could have a material adverse effect on the market price of our common stock. 

In addition, on December 30, 2015, we filed a registration statement on Form S-3 (File No. 333-208800), which was declared effective by the SEC on January 20, 2016, to register for resale 9,353,304 shares of our common stock held by Essex Woodlands, or approximately 42% of our total outstanding shares of common stock as of September 30, 2016. As a result, such shares are freely tradable under the Securities Act of 1933, as amended (the “Securities Act”), and sales of these shares could have a material adverse effect on the market price of our common stock.  

Anti‑takeover provisions in our charter documents and Delaware law might deter acquisition bids for us that you might consider favorable.

Our restated certificate of incorporation and restated bylaws contain provisions that may make the acquisition of our company more difficult without the approval of our board of directors. These provisions:

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law which, subject to certain exceptions, prohibits stockholders owning in excess of 15% of our outstanding voting stock from merging or combining with us. These anti‑takeover provisions and other provisions under Delaware law could discourage, delay or prevent a transaction involving a change in control of our company, even if doing so would benefit our stockholders. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing so as to cause us to take certain corporate actions you desire.

We qualify as an “emerging growth company” as defined in the JOBS Act and will be able to avail ourselves of reduced disclosure requirements applicable to emerging growth companies, which could make our common stock less attractive to investors.

We qualify as an “emerging growth company” as defined in the JOBS Act, and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including certain reduced financial statement reporting obligations, reduced disclosure obligations about our executive compensation arrangements, exemptions from the requirement that we solicit non‑binding advisory votes on executive compensation or golden parachute arrangements, and exemption from the auditor’s attestation requirements of Section 404(b) of the Sarbanes‑Oxley Act. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile. We may take advantage of these reporting exemptions until we are no longer an “emerging growth company.” We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more, (ii) the last day of our fiscal year following the fifth anniversary of the date of the completion of our April 2014 IPO, (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years, or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

We have never paid dividends on our capital stock, and we do not anticipate paying any cash dividends in the foreseeable future.

The continued operation and expansion of our business will require substantial funding. Accordingly, we do not anticipate that we will pay any cash dividends on shares of our common stock for the foreseeable future. We are also restricted from paying dividends under the term loan agreement with CRG. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon results of operations, financial condition, contractual restrictions, restrictions imposed by applicable law and other factors our board of directors deems relevant.

Accordingly, realization of any gain on your investment in our common stock will depend entirely on the appreciation of the price of our common stock, which may never occur. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 2.  PROPERTIES

Our principal executive offices and research and development operations are located in Menlo Park, California, in a 25,000 square foot building, which houses full product research and development capabilities, including proprietary drug delivery research in novel polymer blending and formulations; system design and engineering; prototyping and manufacturing for early clinical studies; analytical, quality assurance and quality control; nonclinical and early clinical development; and regulatory capabilities for clinical development and clinical scale manufacture. We have been in our current Menlo Park location for eight years and the term of our current Menlo Park lease expires December 2020. We also plan to evaluate opportunities for facility expansion or relocation.

Our manufacturing facilities are located in Grand Rapids, Michigan in three buildings, comprising approximately 200,000 square feet. We manufacture all of our current commercial products at these facilities. We also perform process development, prototyping, pilot and commercial manufacturing and quality control in our labs in Grand Rapids. We are qualified for prescription transdermal, dermal, mucosal and wound care products as well as OTC products. The facility is FDA and DEA registered and ISO9001 and ISO13485 certified.

We lease two of our three existing buildings in Grand Rapids on a long-term basis. One building is dedicated to shipping and receiving, inventory and warehousing, but the space has been improved for multipurpose use. Our warehouse lease expires in 2019. The other two buildings house all commercial manufacturing as well as administrative offices. We also own a four-acre lot across the street from the commercial manufacturing operations for planned future expansion.

ITEM 3.  LEGAL PROCEEDINGS

From time to time, we are involved in various legal proceedings arising from the normal course of business activities.

On September 23, 2016, a complaint was filed against us by LBA Realty Fund III-Company VII, LLC, a Delaware Limited Liability Company in the Superior Court of California, County of Alameda, LBA Realty Fund III-Company VII, LLC vs. Corium International, Inc., alleging breach of contract with respect to the lease agreement dated February 12, 2016 between the landlord and us. The Complaint alleges that we breached the lease when we provided written notice to the landlord to terminate the lease on July 29, 2016 and seeks damages in excess of $10.0 million as well as declaratory relief. On or about November 16, 2016, we filed our answer generally denying the allegations and setting forth our defenses.  At the same time, we also filed a cross-complaint seeking compensatory damages, among other relief, for the landlord’s material breaches with respect to the lease agreement.  An initial case management conference is scheduled for February 8, 2017.  The parties have not yet exchanged discovery.  No trial date has been set. At this time, we are unable to assess whether any loss or adverse effect on our financial condition is reasonably possible as a result of this lawsuit or to estimate the range of any potential loss.  We do not believe that this lawsuit has any merit, and we plan to defend vigorously against this claim.

Otherwise, we are not presently a party to any litigation the outcome of which, we believe, if determined adversely against us, would individually or in the aggregate have a material adverse effect on our business, operating results, cash flows or financial condition.
