Our Company

Overview

We are a biopharmaceutical company dedicated todeveloping targeted, receptor-specific peptide therapeutics for the developmenttreatment of peptide, peptide mimeticdiseases with significant unmet medical need and small molecule agonist compounds with a focuscommercial potential. Our programs are based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. WeOur primary product in clinical development is a combination drug-device product for the delivery of bremelanotide for the treatment of female sexual dysfunction, or FSD. In addition, we have a pipeline ofdrug candidates or development programs targetingfor obesity, erectile dysfunction, cardiovascular diseases, pulmonary diseases, inflammatory diseases and dermatologic diseases.

The following drug development programs are actively under development:

Bremelanotide, an on-demand subcutaneous injectable peptide melanocortin and natriuretic receptors, including development of proposed productsreceptor agonist, for treatment of FSD in premenopausal women. Bremelanotide, which is a melanocortin agonist (a compound which binds to a cell receptor and activates a response), is a synthetic peptide analog of the naturally occurring hormone alpha-MSH (melanocyte-stimulating hormone). The novel mechanism of action involves activating endogenous melanocortin hormone pathways involved in sexual dysfunction, acute asthma, heart failure, hypertension, obesity, diabetes and metabolic syndrome.arousal response. Bremelanotide is scheduled to start Phase 3 clinical trials in the last quarter of calendar 2014;
Our Product Candidates
We currently have the following active drug development programs:
·Bremelanotide, a peptide melanocortin receptor agonist, for treatment of sexual dysfunction, targeting female sexual dysfunction (FSD) and erectile dysfunction (ED) in patients non-responsive to current therapies.
·Peptide melanocortin receptor agonists for treatment of FSD and ED.
·PL-3994, a peptide mimetic natriuretic peptide receptor A (NPR-A) agonist, for treatment of acute exacerbations of asthma, heart failure and refractory or difficult-to-control hypertension.
We have licensed several families of melanocortin receptor-basedMelanocortin receptor-4, or MC4r, compounds for treatment of obesity and diabetes and related metabolic syndrome toin collaboration with AstraZeneca AB (AstraZeneca) pursuant to our research collaboration and license agreementagreement. Results of our studies involving MC4r peptides suggest that certain of these peptides may have significant commercial potential for treatment of conditions responsive to MC4r activation, including FSD, erectile dysfunction, obesity and diabetes;
PL-3994, a peptide mimetic natriuretic peptide receptor A, or NPR-A, agonist, for treatment of cardiovascular and pulmonary indications. PL-3994 is our lead natriuretic peptide receptor product candidate, and is a synthetic mimetic of the neuropeptide hormone ANP. PL-3994 is in development for treatment of heart failure, acute exacerbations of asthma and refractory hypertension; and
Melanocortin receptor-1, or MC1r, agonist peptides, for treatment of inflammatory and dermatologic disease indications. Our MC1r peptide drug candidates are highly specific, with AstraZeneca.substantially greater binding and efficacy at MC1r than at other melanocortin receptors. We have selected one of our MC1r peptide drug candidates, designated PL-8177, as a clinical trial candidate.

Recent Events
Reverse Stock Split. On September 24, 2010, we announced that we were implementing a one-for-ten reverse stock split

TABLE OF CONTENTS

The following chart shows the status of our common stock, which had been authorized by our stockholders at our annual meeting held on May 13, 2010. The reverse stock split, which became effective on September 27, 2010, reduced the number of shares of our common stock issued and outstanding from approximately 118.2 million to approximately 11.8 million.

Realignment of Resources. On September 24, 2010, we announced our strategic decision to focus resources and efforts on clinical trials for bremelanotide and PL-3994 and preclinicaldrug development of an inhaled formulation of PL-3994 and a new peptide drug candidate for sexual dysfunction. As part of this decision, we have suspended further research and development efforts on new product candidates and are implementing a reduction in staffing levels. We anticipate having no more than twenty employees by December 31, 2010.

TABLE OF CONTENTS

We will require substantial additional funding to achieve our goals, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our product development, other operations or commercialization efforts;
We have limited control over development activities in Europe for our lead product candidate, bremelanotide for FSD, including regulatory approvals, and no direct control over commercialization efforts due to an agreement with Gedeon Richter Plc, or Gedeon Richter. If Gedeon Richter fails in obtaining regulatory approval or market acceptance of bremelanotide for FSD in Europe, we may be unable to generate any revenue or business for bremelanotide for FSD in Europe;
CompanyIf our efforts to protect our intellectual property related to bremelanotide for FSD or any future product candidates are not adequate, we may not be able to compete effectively in our market; and
We rely on a small management team and staff as well as various contractors and consultants to provide critical services to us, including services related to our clinical programs for bremelanotide and PL-3994 and our preclinical programs for MC1r and MC4r peptide drug candidates. Such programs could be adversely affected if we lose the services of existing key personnel.

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below and other information included in this prospectus, including the financial statements and related notes that appear at the end of this prospectus, before deciding to invest in our securities. These risks should be considered in conjunction with any other information included herein, including in conjunction with forward-looking statements made herein.

Additional risks and uncertainties that we do not presently know or that we currently deem immaterial may also impair our business, financial condition, operating results of operations and prospects.

Risks Relating to our Company


Our Financial Results and Need for Financing

We willhave incurred substantial losses and expect to continue to incur substantial losses over the next few years and we may never become profitable.

We have never been profitable and we may never become profitable. As of June 30, 2010,2014, we had an accumulated deficit of $209.2$274.0 million. We expect to incur additional losses as we continue our development of bremelanotide, PL-3994 and other product candidates. UnlessThese losses, among other things, have had and untilwill continue to have an adverse effect on our stockholders’ equity, total assets and working capital.

Since 2005 we receive approvalhave not had any products available for commercial sale and we have received no revenues from the U. S. Food and Drug Administration (FDA) or other equivalent regulatory authorities outside the United States, we cannot sellsale of our products and will not have product revenues from them. Therefore, forcandidates. For the foreseeable future, we will have to fund all of our operations and capital expenditures from reimbursements and other contract revenue under collaborative development agreements, existing cash balances and outside sources of financing, which may not be available on acceptable terms, if at all. Unless and until we receive approval from the United States Food and Drug Administration, or FDA, or other equivalent regulatory authorities outside the United States, we cannot sell our products and will not have product revenues from them. We have devoted substantially all of our efforts to research and development, including preclinical and clinical trials. Because of the numerous risks associated with developing drugs, we are unable to predict the extent of future losses, whether or when any of our product candidates will become commercially available, or when we will become profitable, if at all.

We have a ll.limited operating history upon which to base an investment decision.

Our operations are primarily focused on acquiring, developing and securing our proprietary technology, conducting preclinical and clinical studies and formulating and manufacturing on a small-scale basis our principal product candidates. These operations provide a limited basis for stockholders to assess our ability to commercialize our product candidates.

We have not yet demonstrated our ability to perform the functions necessary for the successful commercialization of any of our current product candidates. The successful commercialization of our product candidates will require us to perform a variety of functions, including:

continuing to conduct preclinical development and clinical trials;
participating in regulatory approval processes;
formulating and manufacturing products, or having third parties formulate and manufacture products;
post-approval monitoring and surveillance of our products;
conducting sales and marketing activities, either alone or with a partner; and
obtaining additional capital.

If we are unable to obtain regulatory approval of any of our product candidates, to successfully commercialize any products for which we receive regulatory approval or to obtain additional capital, we may not be able to recover our investment in our development efforts.


 
We need

TABLE OF CONTENTS

The clinical and commercial success of our product candidates will depend on a number of factors, including the following:

the ability to raise additional fundscapital on acceptable terms, or at all;
timely completion of our clinical trials, which may be significantly slower or cost more than we currently anticipate and will needdepend substantially upon the performance of third-party contractors;
whether we are required by the FDA or similar foreign regulatory agencies to conduct additional clinical trials beyond those planned to support the approval and commercialization of our product candidates or any future product candidates;
acceptance of our proposed indications and primary endpoint assessments relating to the proposed indications of our product candidates by the FDA and similar foreign regulatory authorities;
our ability to demonstrate to the satisfaction of the FDA and similar foreign regulatory authorities, the safety and efficacy of our product candidates or any future product candidates;
the prevalence, duration and severity of potential side effects experienced with our product candidates or future approved products, if any;
the timely receipt of necessary marketing approvals from the FDA and similar foreign regulatory authorities;
achieving and maintaining, and, where applicable, ensuring that our third-party contractors achieve and maintain, compliance with our contractual obligations and with all regulatory requirements applicable to our product candidates or any future product candidates or approved products, if any;
the ability of third parties with whom we contract to manufacture clinical trial and commercial supplies of our product candidates or any future product candidates, remain in good standing with regulatory agencies and develop, validate and maintain commercially viable manufacturing processes that are compliant with GMP;
a continued acceptable safety profile and efficacy during clinical development and following approval of our product candidates or any future product candidates;
our ability to successfully commercialize our product candidates or any future product candidates in the United States and internationally, if approved for marketing, sale and distribution in such countries and territories, whether alone or in collaboration with others;
acceptance by physicians and patients of the benefits, safety and efficacy of our product candidates or any future product candidates, if approved, including relative to alternative and competing treatments;
our and our partners’ ability to establish and enforce intellectual property rights in and to our product candidates or any future product candidates;
our and our partners’ ability to avoid third-party patent interference or intellectual property infringement claims; and
our ability to in-license or acquire additional product candidates or commercial-stage products that we believe can be successfully developed and commercialized.

If we do not achieve one or more of these factors, many of which are beyond our control, in a timely manner or at all, we could experience significant delays or an inability to obtain regulatory approvals or commercialize our product candidates. Even if regulatory approvals are obtained, we may never be able to successfully commercialize any of our product candidates. Accordingly, we cannot assure you that we will be able to generate sufficient revenue through the sale of our product candidates or any future product candidates to continue our business.

We will need additional financing, including financing to raise fundssubmit required regulatory applications to the FDA for bremelanotide for FSD and to complete clinical trials for our other product candidates, which may be difficult to obtain.

As of June 30, 2014, we had cash and cash equivalents of $12.2 million, with current liabilities of $1.8 million net of unearned revenues of $1.0 million. In September 2014, we received $8.8 million pursuant to our agreement with Gedeon Richter to co-develop and commercialize bremelanotide for FSD in the future,European Union, other European countries and additional selected countries. We believe we have sufficient currently available working capital to fund our planned operations through the quarter ending September 30, 2015, not including initiation of our pivotal Phase 3 clinical trials for bremelanotide for FSD or other planned clinical trials and the proceeds from this offering. Following this offering, assuming the Phase 3 clinical trials of bremelanotide for FSD are successful, as to which there can be no assurance, we will need additional funding to complete submission of required regulatory applications to the FDA for bremelanotide for FSD. We will also need additional funding to complete required clinical trials for our other product candidates and, assuming those clinical trials are successful, as to which there can be no assurance, to complete submission of required regulatory applications to the FDA.

We are preparing to initiate Phase 3 clinical trials of bremelanotide for FSD, and intend to start patient enrollment in the Phase 3 program in the fourth quarter of calendar 2014, but may curtail or delay clinical trial initiation unless we have adequate funds, or commitments for adequate funds, to complete Phase 3 clinical trials. We estimate that the Phase 3 program, including regulatory filings for product approval, will cost at least $80.0 million. In addition to this offering, we will seek funds to support the Phase 3 program through collaborative arrangements on bremelanotide in addition to our agreement with Gedeon Richter, including marketing and distribution partnering agreements, public or private equity or debt financings, and other sources, but such additional funding may not be available on acceptable terms, or at all.

We have curtailedmust depend on financing or partnering to sustain our operations significantly, including suspending early stage research and discovery programs and implementing a reduction in our workforce. However, our available working capital will not fund our currently planned operations for the next twelve months. We will also need additional funds to continue development of bremelanotide and PL-3994, including planned clinical trials and preclinical development efforts.

operations. We may raise additional funds through this offering or through other public or private equity financings,or debt financings, collaborative arrangements on our product candidates, or other sources. However, additional funding may not be available on acceptable terms, or at all. To obtain additional funding, we may need to enter into arrangements that require us to develop only certain of our product candidates or relinquish rights to certain technologies, product candidates and/or potential markets.

If we are unable to raise sufficient additional funds when needed, we will implement plans for the orderly wind down of our business operations, including curtailingmay be required to curtail operations significantly, cease clinical trials and further decreasingdecrease staffing levels, and willlevels. We may seek to license, sell or otherwise dispose of our product candidates, technologies and contractual rights including rights under our research collaboration and license agreement with AstraZeneca, on the best possible terms available. Even if we are able to license, sell or otherwise dispose of our product candidates, technologies and contractual rights, it is likely to be on unfavorable terms and for less value than if we had the financial resources to develop or otherwise advance our product candidates, technologies and contractual rights ourselves.

Our future capital requirements depend on many factors, including:

the results of our Phase 3 clinical trials for bremelanotide for FSD;
the timing of, and the costs involved in, obtaining regulatory approvals for bremelanotide for FSD and our other product candidates;
the number and characteristics of any additional product candidates we develop or acquire;
the scope, progress, results and costs of researching and developing bremelanotide for FSD, PL-3994 or any future product candidates, and conducting preclinical and clinical trials;
the cost of commercialization activities if bremelanotide for FSD, PL-3994 or any future product candidates are approved for sale, including marketing, sales and distribution costs;

Raising additional capital may cause dilution to existing shareholders, restrict our operations or require us to relinquish rights.

We are continually evaluating opportunitiesmay seek the additional capital necessary to raise additional f undsfund our operations through public or private equity offerings, collaboration agreements, debt financings or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing shareholders’ ownership interests will be diluted and the terms may include liquidation or other preferences that adversely affect their rights as a shareholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us.

Risks Related to Our Business, Strategy and Industry

We are substantially dependent on the clinical and commercial success of our product candidates, primarily our lead product candidate, bremelanotide for FSD, which is in Phase 3 clinical development. We cannot be certain that we will be able to obtain regulatory approval for or successfully commercialize any of our product candidates.

To date, we have invested most of our efforts and financial resources in the research and development of bremelanotide for FSD, which is currently our lead product candidate. We are currently in Phase 3 clinical development in the United States for bremelanotide for FSD. Our near-term prospects, including our ability to finance our company and generate revenue, will depend heavily on the successful development, regulatory approval and commercialization of bremelanotide for FSD, as well as evaluating prospective business partners, and will continue to do so. However, if adequate funds are not available to us when we need it, and we are unable to enter into some form of strategic relationship that will give us access to

 additional cash resources, we will be required to even further curtail our operations which would, in turn, further raise substantial doubt about our ability to continue as a going concern.
We have a limited operating history upon which to base an investment decision.
Our operations are primarily focused on acquiring, developing and securing our proprietary technology, conducting preclinical and clinical studies and formulating and manufacturing on a small-scale basis our principal product candidates. These operations provide a limited basis for stockholders to assess our ability to commercialize our product candidates.
We have not yet demonstrated our ability to perform the functions necessary for the successful commercialization of any of our currentfuture product candidates. The successful commercializationclinical and commercial success of our product candidates will require usdepend on a number of factors, including the following:

timely completion of, or need to perform a varietyconduct additional, clinical trials, including our Phase 3 clinical trials in the United States for bremelanotide for FSD, which may be significantly slower or cost more than we currently anticipate and will depend substantially upon the accurate and satisfactory performance of functions, including:third-party contractors;
our ability to demonstrate to the satisfaction of the FDA the safety and efficacy of bremelanotide for FSD or any future product candidates through clinical trials;
whether we are required by the FDA or other similar foreign regulatory agencies to conduct additional clinical trials to support the approval of bremelanotide for FSD or any future product candidates;

·obtaining additional capital.
our ability to successfully commercialize bremelanotide for FSD or any future product candidates, if approved for marketing and sale, whether alone or in collaboration with others;
our ability to enforce our intellectual property rights in and to bremelanotide for FSD or any future product candidates;
our ability to avoid third-party patent interference or intellectual property infringement claims;
acceptance of bremelanotide for FSD or any future product candidates, if approved, as safe and effective by patients and the medical community; and
a continued acceptable safety profile and efficacy of bremelanotide for FSD or any future product candidates following approval.

If we do not achieve one or more of these factors, many of which are beyond our control, in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our product candidates. Accordingly, we cannot assure you that we will be able to generate sufficient revenue through the sale of bremelanotide for FSD or any future product candidate to continue our business.

Our product candidates are still in the early stages of development and remain subject to clinical testing and regulatory approval. If we are unable to obtain regulatory approval of any ofsuccessfully develop and test our product candidates, to successfully commercialize any products for which we receive regulatory approval or to obtain additional capital, we maywill not be able to recover our investment in our development efforts.

Budget constraints negatively impact our research and development, forcing us to delay our efforts to develop certain product candidates in favor of developing others, which may prevent us from commercializing our product candidates as quickly as possible.
Research and development is an expensive process. As part of our plan to realign resources, we have decided to focus resources and efforts on clinical trials for bremelanotide and PL-3994 and preclinical development of an inhaled formulation of PL-3994 and a new peptide drug candidate for sexual dysfunction. As part of this decision, we have suspended further research and development efforts on new product candidates. We do not currently have sufficient funds to progress the programs we have prioritized, and clinical trial and development priorities may change depending on terms required by investors in our company, including investors in this offering. Because we have had to prioritize our development candidates as a result of budget constraints, and because these priorities may change, we may not be able to fully realize the value of our product candidates in a timely manner, if at all.
Development and commercialization of our product candidates involves a lengthy, complex and costly process, and we may never successfully develop or commercialize any product.
successful.

Our product candidates are at various stages of research and development, will require regulatory approval, and may never be successfully developed or commercialized. Our product candidates will require significant further research, development and testing before we can seek regulatory approval to market and sell them.

We must demonstrate that our product candidates are safe and effective for use in patients in order to receive regulatory approval for commercial sale. Preclinical studies in animals, using various doses and formulations, must be performed before we can begin human clinical trials. Even if we obtain favorable results in the preclinical studies, the results in humans may be different. Numerous small-scale human clinical trials may be necessary to obtain initial data on a product candidate’s safety and efficacy in humans before advancing to large-scalelarge scale human clinical trials. We face the risk that the results of our trials in later phases of clinical trials


TABLE OF CONTENTS

may be inconsistent with those obtained in earlier phases. Adverse or inconclusive results could delay the progress of our developme ntdevelopment programs and may prevent us from filing for regulatory approval of our product candidates. Additional factors that can cause delay or terminationcould inhibit the successful development of our humanproduct candidates include:

lack of effectiveness of any product candidate during clinical trials include:or the failure of our product candidates to meet specified endpoints;
failure to design appropriate clinical trial protocols;
·the availability of sufficient capital to sustain operations and clinical trials;
uncertainty regarding proper dosing;
inability to develop or obtain a supplier for an autoinjector device that meets the FDA’s medical device requirements;
·timely completion of clinical site protocol approval and obtaining informed consent from subjects;
insufficient data to support regulatory approval;
inability or unwillingness of medical investigators to follow our clinical protocols;
·the rate of patient enrollment in clinical studies;
inability to add a sufficient number of clinical trial sites; or
the availability of sufficient capital to sustain operations and clinical trials.

·adverse medical events or side effects in treated patients; and
·lack of effectiveness of the product being tested.

You should evaluate us in light of these uncertainties, delays, difficulties and expenses commonly experienced by early stage biopharmaceutical companies, as well as unanticipated problems and additional costs relating to:

product approval or clearance;
regulatory compliance;
good manufacturing practices;
intellectual property rights;
product introduction; and
marketing and competition.

If clinical trials for our product candidates are prolonged or delayed, we may be unable to commercialize our product candidates on a timely basis, which would require us to incur additional costs and delay our receipt of any revenue from potential product sales.

We may be unable to commercialize our product candidates on a timely basis due to unexpected delays in our human clinical trials. Potential delaying events include:

discovery of serious or unexpected toxicities or side effects experienced by study participants or other safety issues;
slower than expected rates of subject recruitment and enrollment rates in clinical trials resulting from numerous factors, including the prevalence of other companies’ clinical trials for their product candidates for the same indication, or clinical trials for indications for which patients do not as commonly seek treatment;
difficulty in retaining subjects who have initiated a clinical trial but may withdraw at any time due to adverse side effects from the therapy, insufficient efficacy, fatigue with the clinical trial process or for any other reason;
difficulty in obtaining institutional review board, or IRB, approval for studies to be conducted at each site;
delays in manufacturing or obtaining, or inability to manufacture or obtain, sufficient quantities of materials for use in clinical trials;
inadequacy of or changes in our manufacturing process or the product formulation or method of delivery;
changes in applicable laws, regulations and regulatory policies;

 
·product approval or clearance;

TABLE OF CONTENTS

delays or failure in reaching agreement on acceptable terms in clinical trial contracts or protocols with prospective contract research organizations, or CROs, clinical trial sites and other third-party contractors;
failure of our CROs or other third-party contractors to comply with contractual and regulatory requirements or to perform their services in a timely or acceptable manner;
failure by us, our employees, our CROs or their employees or any partner with which we may collaborate or their employees to comply with applicable FDA or other regulatory requirements relating to the conduct of clinical trials or the handling, storage, security and recordkeeping for drug, medical device and biologic products;
delays in the scheduling and performance by the FDA of required inspections of us, our CROs, our suppliers, or our clinical trial sites, and violations of law or regulations by discovered in the course of FDA inspections;
scheduling conflicts with participating clinicians and clinical institutions; or
difficulty in maintaining contact with subjects during or after treatment, which may result in incomplete data.

Any of these events or other delaying events, individually or in the aggregate, could delay the commercialization of our product candidates and have a material adverse effect on our business, results of operations and financial condition.

Even if our product candidates receive regulatory approval, they may never achieve market acceptance, in which case our business, financial condition and results of operation will be materially adversely affected.

Regulatory approval for the marketing and sale of any of our product candidates does not assure the product’s commercial success. Any approved product will compete with other products manufactured and marketed by major pharmaceutical and other biotechnology companies. If any of our product candidates are approved by the FDA and do not achieve adequate market acceptance, our business, financial condition and results of operations will be materially adversely affected. The degree of market acceptance of any such product will depend on a number of factors, including:

perceptions by members of the healthcare community, including physicians, about its safety and effectiveness;
cost-effectiveness relative to competing products and technologies;
availability of reimbursement for our products from third-party payers such as health insurers, health maintenance organizations and government programs such as Medicare and Medicaid; and
advantages over alternative treatment methods.

There are currently no FDA approved products for treatment of FSD. As a result, the actual market size and market dynamics are unknown, and there is significant uncertainty concerning the extent and scope of third-party reimbursement for products treating FSD. While we believe that an on-demand drug for FSD has competitive advantages compared to chronic or daily use hormones and other drugs, we may not be able to realize this perceived advantage in the market. Bremelanotide is administered by subcutaneous injection. While the single-use, disposable autoinjector format is designed to maximize market acceptability, bremelanotide as a subcutaneous injectable drug for FSD may never achieve significant market acceptance. In addition, we believe reimbursement of bremelanotide from third-party payers such as health insurers, HMOs or other third-party payers of healthcare costs will be limited, and that the ultimate user will pay all or a substantial part of the cost of bremelanotide for FSD. If the market opportunity for bremelanotide is smaller than we anticipate, it may also be difficult for us to find marketing partners and, as a result, we may be unable to generate revenue and business from bremelanotide. If bremelanotide for FSD does not achieve adequate market acceptance at an acceptable price point, our business, financial condition and results of operations will be materially adversely affected.


 
·regulatory compliance;

TABLE OF CONTENTS

Even if our product candidates receive regulatory approval in the United States, we may never receive approval or commercialize our products outside of the United States.

In order to market any products outside of the United States, we must establish and comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from that required to obtain FDA approval. The regulatory approval process in other countries may include all of the risks detailed above regarding FDA approval in the United States as well as other risks. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setbacks in obtaining such approval would impair our ability to develop foreign markets for our product candidates and may have a material adverse effect on our results of operations and financial condition.

If side effects emerge that can be linked to our product candidates that are in development or after they are approved and on the market, we may be required to perform lengthy additional clinical trials, change the labeling of any such products, or withdraw such products from the market, any of which would hinder or preclude our ability to generate revenues.

If we identify side effects or other problems occur in future clinical trials, we may be required to terminate or delay clinical development of the product candidate. Furthermore, even if any of our product candidates receive marketing approval, as greater numbers of patients use a drug following its approval, if the incidence of side effects increases or if other problems are observed after approval that were not seen or anticipated during pre-approval clinical trials, a number of potentially significant negative consequences could result, including:

regulatory authorities may withdraw their approval of the product;
we may be required to reformulate such products or change the way the product is manufactured;
we may become the target of lawsuits, including class action suits; and
our reputation in the market place may suffer resulting in a significant drop in the sales of such products.

Any of these events could substantially increase the costs and expenses of developing, commercializing and marketing any such product candidates or could harm or prevent sales of any approved products.

The number of subjects in our study pools in our clinical trials may be deemed by regulators to be too small.

Our clinical trials have been conducted on a pool of subjects that is structured for such research. Nevertheless, there is the possibility that for statistical reasons, the pool of subjects may be determined by the FDA or another regulatory body to be too small to verify statistical significance. In such a case, the conclusions from the previous trials will need to be established with at least another set of clinical trials testing the relevant issue.

We may not be able to keep up with the rapid technological change in the biotechnology and pharmaceutical industries, which could make any future approved products obsolete and reduce our revenue.

Biotechnology and related pharmaceutical technologies have undergone and continue to be subject to rapid and significant change. Our future will depend in large part on our ability to maintain a competitive position with respect to these technologies. Our competitors may render our technologies obsolete by advances in existing technological approaches or the development of new or different approaches, potentially eliminating the advantages in our drug discovery process that we believe we derive from our research approach and proprietary technologies. In addition, any future products that we develop, including our clinical product candidates, may become obsolete before we recover expenses incurred in developing those products, which may require that we raise additional funds to continue our operations.

Competing products and technologies may make our proposed products noncompetitive.

There are other products being developed for FSD, including flibanserin, a daily-use oral drug being developed for hypoactive sexual desire disorder, and a number of oral combination drugs and daily-use oral and patch drugs incorporating testosterone. There is competition to develop drugs for treatment of FSD in both premenopausal and postmenopausal patients. Our bremelanotide drug product is intended to be administered by subcutaneous injection, and an on-demand drug product for the same indication which utilizes another route of administration, such as a conventional oral drug product, may make subcutaneous bremelanotide noncompetitive.

There are three oral FDA-approved PDE-5 inhibitor drugs for the treatment of erectile dysfunction, or ED, other approved products and devices for ED, and other products in development for treatment of ED, including products in clinical trials.

There is competition to develop drugs for ED in patients non-responsive to PDE-5 inhibitor drugs, and to develop drugs for treatment of FSD.

There are several products approved for use in treatment of obesity and related indications, and a number of other products being developed for treatment of obesity, including products in clinical trials. There is intense competition to develop drugs for treatment of obesity and related indications.

There are a number of products approved for use in treating inflammatory diseases and dermatologic indication, and other products being developed, including products in clinical trials.

We are aware of one recombinant natriuretic peptide product for acutely decompensated congestive heart failure approved and marketed in the United States, and another recombinant natriuretic peptide product approved and marketed in Japan. Clinical trials on other natriuretic peptide products are being conducted in the United States. In addition, other products for treatment of heart failure are either currently being marketed or in development, including a combination drug which increases active levels of the neuropeptide hormone atrial natriuretic peptide, or ANP.

There are numerous products approved for use in treatment of asthma, and a number of other products being developed for treatment of acute exacerbations of asthma, including products in clinical trials. There is intense competition to develop drugs for treatment of acute exacerbations of asthma.

The biopharmaceutical industry is highly competitive. We are likely to encounter significant competition with respect to bremelanotide, other melanocortin receptor agonist compounds and PL-3994. Most of our competitors have substantially greater financial and technological resources than we do. Many of them also have significantly greater experience in research and development, marketing, distribution and sales than we do. Accordingly, our competitors may succeed in developing, marketing, distributing and selling products and underlying technologies more rapidly than we can. These competitive products or technologies may be more effective and useful or less costly than bremelanotide, other melanocortin receptor agonist compounds or PL-3994. In addition, academic institutions, hospitals, governmental agencies and other public and private research organizations are also conducting research and may develop competing products or technologies on their own or through strategic alliances or collaborative arrangements.

We rely on third parties over whom we have no control to conduct clinical trials for our product candidates and their failure to timely perform their obligations could significantly harm our product development.

We have limited research or development staff and do not have dedicated research or development facilities. We rely on third parties and independent contractors such as researchers at CROs and universities in certain areas that are particularly relevant to our research and product development plans. We engage such researchers to conduct our preclinical studies, clinical trials and associated tests. These outside contractors are not our employees and may terminate their engagements with us at any time. In addition, we have limited control over the resources that these contractors devote to our programs and they may not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such programs ourselves. There is also competition for these relationships, and we may not be able to maintain our relationships with our contractors on acceptable terms. If our third-party contractors do not carry out their duties under their agreements with us, fail to inform us if our clinical trials fail to comply with clinical trial protocols or fail to


 
·intellectual property rights;

TABLE OF CONTENTS

meet expected deadlines, our ability to develop our product candidates and obtain regulatory approval on a timely basis, if at all, may be materially adversely affected.

Production and supply of our product candidates depend on contract manufacturers over whom we have no control.

We do not have the facilities to manufacture bremelanotide, the autoinjector component of our bremelanotide combination product, PL-3994, PL-8177, other melanocortin receptor agonist compounds or our other potential products. Our contract manufacturers must perform these manufacturing activities in a manner that complies with FDA regulations. Our ability to control third-party compliance with FDA requirements will be limited to contractual remedies and rights of inspection. The manufacturers of approved products and their manufacturing facilities will be subject to continual review and periodic inspections by the FDA and other authorities where applicable, and must comply with ongoing regulatory requirements, including FDA regulations concerning GMPs. Failure of third-party manufacturers to comply with GMPs, medical device quality systems regulations, or QSR, or other FDA requirements may result in enforcement action by the FDA. Failure to conduct their activities in compliance with FDA regulations could delay our development programs or negatively impact our ability to receive FDA approval of our potential products or continue marketing if they are approved. Establishing relationships with new suppliers, who must be FDA-approved, is a time-consuming and costly process.

Use of third-party manufacturers may increase the risk that we will not have adequate suppliers of our product candidates or products.

Reliance on third-party manufacturers entails risk, to which we would not be subject if we manufactured product candidates or products ourselves, including:

reliance on the third party for regulatory compliance and quality assurance;
the possible breach of the manufacturing agreement by the third party because of factors beyond our control;
the possible termination or non-renewal of the agreement by the third party, based on its own business priorities, at a time that is costly or inconvenient for us; and
drug product supplies not meeting the requisite requirements for clinical trial use.

If we are not able to obtain adequate supplies of our product candidates, it will be more difficult for us to develop our product candidates and compete effectively. Our product candidates and any products that we and/or our potential future collaborators may develop may compete with other product candidates and products for access to manufacturing facilities.

We have no experience in marketing, distributing and selling products and will substantially rely on our marketing partners to provide these capabilities.

We do not have marketing partners for any of our products, including bremelanotide and PL-3994, except that Gedeon Richter is expected to market, or be responsible for marketing, bremelanotide for FSD in Europe and selected other territories. If any of these products are approved by the FDA or other regulatory authorities, we must either develop marketing, distribution and selling capacity and expertise, which will be costly and time consuming, or enter into agreements with other companies to provide these capabilities. We may not be able to enter into suitable agreements on acceptable terms, if at all.

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

We do not currently have an organization nor have any experience in sales, marketing and distribution of pharmaceutical products. We will need to establish sales and marketing capabilities or establish and maintain agreements with third parties to market and sell our product candidates. In order to market any products that may be approved by the FDA or similar foreign regulatory authorities, we must build our sales, marketing, managerial and other non-technical capabilities, license to a commercial partner, or make arrangements with


 
·product introduction; and

TABLE OF CONTENTS

third parties to perform these services. There are risks involved with entering into arrangements with third parties to perform these services, which could delay the commercialization of any of our product candidates, if approved for commercial sale. If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate product revenue and our business would suffer. In addition, if we enter into arrangements with third parties to perform sales, marketing and distribution services, our product revenues are likely to be lower than if we could market and sell any products that we develop ourselves.

We do not control the development of compounds licensed to third parties and, as a result, we may not realize a significant portion of the potential value of any such license arrangements.

Under our license, co-development and commercialization agreement with Gedeon Richter for bremelanotide for FSD in a licensed territory, we have limited control over development activities, including regulatory approvals, and no direct control over commercialization efforts. Gedeon Richter may abandon further development of bremelanotide in its licensed territory, including terminating the agreement, for any reason, including a change of priorities within Gedeon Richter or lack of success in clinical trials necessary for obtaining regulatory approvals. Because the potential value of the license arrangement with Gedeon Richter is contingent upon the successful development and commercialization of bremelanotide for FSD in the licensed territory, the ultimate value of this license will depend on the efforts of Gedeon Richter. If Gedeon Richter does not succeed in obtaining regulatory approval of bremelanotide for FSD in the licensed territory for any reason, or does not succeed in securing market acceptance of bremelanotide for FSD in the territory, or elects for any reason to discontinue development of bremelanotide for FSD, we may be unable to realize the potential value of this arrangement.

Under our research collaboration and license agreement with AstraZeneca for melanocortin-based therapeutic compounds for obesity, diabetes and related metabolic syndrome, we have no direct control over the development of compounds and have only limited, if any, input on the direction of development efforts. Based on a serious adverse event, AstraZeneca has decided to discontinue development of AZD2820, a subcutaneously administered peptide melanocortin-4 receptor partial agonist developed during their research collaboration with us. AstraZeneca may decide to abandon further development of this program, including terminating the agreement, if the results of further development efforts are negative or inconclusive, or if priorities within AstraZeneca change, or for any reason. Because the potential value of the license arrangement with AstraZeneca is contingent upon the successful development and commercialization of the licensed technology, the ultimate value of this license will depend on the efforts of AstraZeneca. If AstraZeneca does not succeed in developing the licensed technology for any reason, or elects for any reason to discontinue the development of this program, we will be unable to realize the potential value of this arrangement.

Our ability to achieve revenues from the sale of our products in development will depend, in part, on our ability to obtain adequate reimbursement from Medicare, Medicaid, private insurers and other healthcare payers.

Our ability to successfully commercialize our products in development will depend, in significant part, on the extent to which we or our marketing partners can obtain reimbursement for our products and also reimbursement at appropriate levels for the cost of our products. Obtaining reimbursement from governmental payers, insurance companies, HMOs and other third-party payers of healthcare costs is a time-consuming and expensive process. There is no guarantee that our products will ultimately be reimbursed. There is significant uncertainty concerning third-party reimbursement for the use of any pharmaceutical product incorporating new technology and third-party reimbursement might not be available for our proposed products once approved, or if obtained, might not be adequate.

There are no approved products for treating FSD, and thus there is significant uncertainty concerning the extent and scope of third-party reimbursement for products treating FSD. Based on third-party reimbursement for approved products treating ED, we believe bremelanotide for FSD will be classified as a Tier 3 drug, so that reimbursement will be limited for bremelanotide for treatment of FSD, assuming the product is approved by the FDA. If we are able to obtain reimbursement, continuing efforts by governmental and third-party payers to contain or reduce costs of healthcare may adversely affect our future revenues and ability to achieve profitability. Third-party payers are increasingly challenging the prices charged for diagnostic and therapeutic


 
·marketing and competition.

products and related services. Reimbursement from governmental payers is subject to statutory and regulatory changes, retroactive rate adjustments, administrative rulings and other policy changes, all of which could materially decrease the range of products for which we are reimbursed or the rates of reimbursement by government payers. In addition, recent legislation reforming the healthcare system may result in lower prices or the actual inability of prospective customers to purchase our products in development. The cost containment measures that healthcare payers and providers are instituting and the effect of any healthcare reform could materially and adversely affect our ability to operate profitably. Furthermore, even if reimbursement is available, it may not be available at price levels sufficient for us to realize a positive return on our investment, which would have a material adverse effect on our business, financial condition and results of operations.

Even if we receive regulatory approval for our products in Europe, we may not be able to secure adequate pricing and reimbursement in Europe for us or any strategic partner to achieve profitability.

Even if one or more of our products are approved in Europe, we may be unable to obtain appropriate pricing and reimbursement for such products. In most European markets, demand levels for healthcare in general and for pharmaceuticals in particular are principally regulated by national governments. Therefore, pricing and reimbursement for our products will have to be negotiated on a “Member State by Member State” basis according to national rules, as there does not exist a centralized European process. As each Member State has its own national rules governing pricing control and reimbursement policy for pharmaceuticals, there are likely to be uncertainties attaching to the review process, and the level of reimbursement that national governments are prepared to accept. In the current economic environment, governments and private payers or insurers are increasingly looking to contain healthcare costs, including costs on drug therapies. If we are unable to obtain adequate pricing and reimbursement for our products in Europe, we or a potential strategic partner or collaborator may not be able to cover the costs necessary to manufacture, market and sell the product, limiting or preventing our ability to achieve profitability.

We may incur substantial liabilities and may be required to limit commercialization of our products in response to product liability lawsuits.

The testing and marketing of medical products entails an inherent risk of product liability. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products or cease clinical trials. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with corporate collaborators. We currently carry liability insurance as to certain clinical trial risks. We, or any corporate collaborators, may not in the future be able to obtain insurance at a reasonable cost or in sufficient amounts, if at all. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

We are subject to federal and state healthcare fraud and abuse laws and regulations and could face substantial penalties if we are unable to fully comply with such laws.

We are subject to health care fraud and abuse regulation and enforcement by both the federal government and the states in which we conduct our business. These health care laws and regulations include, for example:

the federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from soliciting, receiving, offering or providing remuneration, directly or indirectly, in return for or to induce either the referral of an individual for, or the purchase order or recommendation of, any item or services for which payment may be made under a federal health care program such as the Medicare and Medicaid programs;
the federal physician self-referral prohibition, commonly known as the Stark Law, which prohibits physicians from referring Medicare or Medicaid patients to providers of “designated health services” with whom the physician or a member of the physician’s immediate family has an ownership interest or compensation arrangement, unless a statutory or regulatory exception applies;

 

TABLE OF CONTENTS

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which established federal crimes for knowingly and willfully executing a scheme to defraud any health care benefit program or making false statements in connection with the delivery of or payment for health care benefits, items or services;
federal false claims laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent, and which may apply to entities like us to the extent that our interactions with customers may affect their billing or coding practices; and
state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payer, including commercial insurers.

If our operations are found to be in violation of any of these laws and regulations, we may be subject to any applicable penalty associated with the violation, including civil and criminal penalties, damages and fines, and/or exclusion from participation in Medicare, Medi-Cal or other state or federal health care programs, we could be required to refund payments received by us, and we could be required to curtail or cease our operations. Any of the foregoing consequences could have a material adverse effect on our business, results of operations and financial condition.

We are highly dependent on our management team, senior staff professionals and third-party contractors and consultants, and the loss of their services could materially adversely affect our business.

We rely on our relatively small management team and staff as well as various contractors and consultants to provide critical services. Our ability to execute our clinical programs for bremelanotide and PL-3994 and our preclinical programs for MC1r and MC4r peptide drug candidates depends on our continued retention and motivation of our management and senior staff professionals, including executive officers and senior members of product development and management who possess significant technical expertise and experience and oversee our development programs. If we lose the services of existing key personnel, our development programs could be adversely affected if suitable replacement personnel are not recruited quickly. Our success also depends on our ability to develop and maintain relationships with contractors, consultants and scientific advisors.

There is competition for qualified personnel, contractors and consultants in the pharmaceutical industry, which makes it difficult to attract and retain the qualified personnel, contractors and consultants necessary for the development and growth of our business. Our failure to attract and retain such personnel, contractors and consultants could have a material adverse effect on our business, results of operations and financial condition.

We will need to hire additional employees in order to commercialize our product candidates in the future. Any inability to manage future growth could harm our ability to commercialize our product candidates, increase our costs and adversely impact our ability to compete effectively.

In order to commercialize our product candidates in the future, we will need to hire experienced sales and marketing personnel to sell and market those product candidates we decide to commercialize, and we will need to expand the number of our managerial, operational, financial and other employees to support commercialization. Competition exists for qualified personnel in the biopharmaceutical field.

Future growth will impose significant added responsibilities on members of management, including the need to identify, recruit, maintain and integrate additional employees. Our future financial performance and our ability to commercialize our product candidates and to compete effectively will depend, in part, on our ability to manage any future growth effectively.

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

Our business, results of operations and financial condition could be adversely affected by general conditions in the global economy and in the global financial markets. Furthermore, the market for FSD may be particularly vulnerable to unfavorable economic conditions. We do not expect bremelanotide for the treatment of FSD to


TABLE OF CONTENTS

be substantially reimbursed by any government or third-party payer and, as a result, demand for this product will be tied to discretionary spending levels of our targeted patient population. The recent global financial crisis caused extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn could result in a variety of risks to our business, including weakened demand for bremelanotide for FSD or any future product candidates, if approved, and our ability to raise additional capital when needed on acceptable terms, if at all. This is particularly true in Europe, which is undergoing a continued severe economic crisis. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruption, or cause our customers to delay making payments for our services. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

Risks Related to Government Regulation

Both before and after marketing approval, our product candidates are subject to ongoing regulatory requirements and, if we fail to comply with these continuing requirements, we could be subject to a variety of sanctions and the sale of any approved commercial products could be suspended.

Both before and after regulatory approval to market a particular product candidate, the manufacturing, labeling, packaging, adverse event reporting, storage, advertising and promotion and record keeping related to the product candidates are subject to extensive regulatory requirements. If we fail to comply with the regulatory requirements of the FDA and other applicable U.S. and foreign regulatory authorities, we could be subject to administrative or judicially imposed sanctions, including:

restrictions on the products or manufacturing process;
warning letters;
civil or criminal penalties;
fines;
injunctions;
imposition of a Corporate Integrity Agreement, or CIA, requiring heightened monitoring of our compliance functions, overseen by outside monitors, and enhanced reporting requirements to, and oversight by, the FDA and other government agencies;
product seizures or detentions and related publicity requirements;
suspension or withdrawal of regulatory approvals;
regulators or IRBs may not authorize us or any potential future collaborators to commence a clinical trial or conduct a clinical trial at a prospective trial site;
total or partial suspension of production; and
refusal to approve pending applications for marketing approval of new product candidates.

Changes in the regulatory approval policy during the development period, changes in or the enactment of additional regulations or statutes, or changes in the regulatory review for each submitted product application may cause delays in the approval or rejection of an application. Even if the FDA approves a product candidate, the approval may impose significant restrictions on the indicated uses, conditions for use, labeling, advertising, promotion, marketing and/or production of such product, and may impose ongoing requirements for post-approval studies, including additional research and development and clinical trials. The approval may also impose risk evaluation mitigation strategies, or REMS, on a product if the FDA believes there is a reason to monitor the safety of the drug in the marketplace. REMS may include requirements for additional training for health care professionals, safety communication efforts and limits on channels of distribution, among other things. The sponsor would be required to evaluate and monitor the various REMS activities and adjust them if need be. The FDA also may impose various civil or criminal sanctions for failure to comply with regulatory requirements, including withdrawal of product approval.


TABLE OF CONTENTS

Furthermore, the approval procedure and the time required to obtain approval varies among countries and can involve additional testing beyond that required by the FDA. Approval by one regulatory authority does not ensure approval by regulatory authorities in other jurisdictions. The FDA has substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical or other studies.

In addition, varying interpretations of the data obtained for preclinical and clinical testing could delay, limit or prevent regulatory approval of a product candidate. Even if we submit an application to the FDA for marketing approval of a product candidate, it may not result in marketing approval from the FDA.

We do not expect to receive regulatory approval for the commercial sale of any of our product candidates that are in development in the near future, if at all. The inability to obtain FDA approval or approval from comparable authorities in other countries for our product candidates would prevent us or any potential future collaborators from commercializing these product candidates in the United States or other countries.

We may not be able to obtain regulatory approval of bremelanotide for FSD even if the product is effective in treating FSD.

Clinical drug development programs for our product candidates are very expensive, time-consuming, difficult to design and implement and their outcome is inherently uncertain. Approval of bremelanotide for treatment of FSD in premenopausal women requires a determination by the FDA that the product is both safe and effective. Our Phase 2B clinical trials for FSD demonstrated an acceptable safety profile and, at selected doses, statistically significant efficacy. However, the FDA may ultimately disagree with our definition of efficacy in FSD, our clinical trial designs, or our interpretation of our clinical trial results. Moreover, results obtained in Phase 3 clinical trials may be inconsistent with results obtained in our Phase 2B trials, and may demonstrate either an unacceptable safety profile or insufficient efficacy. It is also possible that safety or efficacy results obtained in Phase 3 clinical trials will be inconclusive. It is not possible to predict, with any assurance, whether the FDA will approve bremelanotide for any indications. The FDA may deny or delay approval of any application for bremelanotide if the FDA determines that the clinical data do not adequately establish the safety of the drug even if efficacy is established. If FDA approves bremelanotide, the approved labeling of the product may be limited or restricted in such ways as to inhibit or prevent the successful market acceptance and profitability of the product. Bremelanotide could take a significantly longer time to obtain approval than we expect and it may never gain approval. If regulatory approval of bremelanotide is delayed, limited or never obtained, our business, financial condition and results of operations would be materially adversely affected.

The regulatory approval process is lengthy, expensive and uncertain, and may prevent us from obtaining the approvals that we require.

Government authorities in the United States and other countries extensively regulate the advertising, labeling, storage, record-keeping, safety, efficacy, research, development, testing, manufacture, promotion, marketing and distribution of drug products. Drugs are subject to rigorous regulation in the United States by the FDA and similar regulatory bodies in other countries. The steps ordinarily required by the FDA before a new drug may be marketed in the United States include:

completion of non-clinical tests including preclinical laboratory and formulation studies and animal testing and toxicology;
submission to the FDA of an Investigational New Drug, or IND, application, which must become effective before clinical trials may begin, and which may be placed on “clinical hold” by the FDA, meaning the trial may not commence, or must be suspended or terminated prior to completion;
performance of adequate and well-controlled Phase 1, 2 and 3 human clinical trials to establish the safety and efficacy of the drug for each proposed indication, and potentially post-approval or Phase 4 studies to further define the drug’s efficacy and safety, generally or in specific patient populations;
submission to the FDA of a New Drug Application, or NDA, that must be accompanied by a substantial “user fee” payment;

 
·completion of non-clinical tests including preclinical laboratory

TABLE OF CONTENTS

FDA review and approval of the NDA before any commercial marketing or sale; and formulation studies and animal testing and toxicology;
compliance with post-approval commitments and requirements.
·submission to the FDA of an Investigational New Drug (IND) application, which must become effective before clinical trials may begin;
·performance of adequate and well-controlled Phase 1, 2 and 3 human clinical trials to establish the safety and efficacy of the drug for each proposed indication;
·submission to the FDA of a New Drug Application (NDA); and
·FDA review and approval of the NDA before any commercial marketing or sale.

Satisfaction of FDA pre-market approval requirements for new drugs typically takes a number of years and the actual time required for approval may vary substantially based upon the type, complexity and novelty of the product or disease.disease to be treated by the drug. The results of product development, preclinical studies and clinical trials are submitted to the FDA as part of an NDA. The NDA also must contain extensive manufacturing information.information, demonstrating compliance with applicable GMP requirements. Once the submission has been accepted for filing, the FDA generally has ten months to review the application and respond to the applicant. Such response may be an approval, or may be a “complete response letter” outlining additional data or steps that must be completed prior to further FDA review of the NDA. The review process is often significantly extended by FDA requests for additional information or clarification. Success in early stage clinical trials does not assure success in later stage clinical trials. Data obtained from clinical trials is not always conclusive and may be susceptible to varying interpretations that could delay, limit or prevent regulatory approval. The FDA may refer the NDA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved, but the FDA is not bound by the recommendation of the advisory committee. The FDA may deny or delay approval of applications that do not meet applicable regulatory criteria or if the FDA determines that the clinical data do not adequately establish the safety and efficacy of the drug. Therefore, our proposed products could take a significantly longer time than we expect or may never gain approval. If regulatory approval is delayed or never obtained, our business, financial condition and our liquidityresults of operations would be materially adversely affected.

Some of our products or product candidates, including bremalanotide, may be used in combination with a drug delivery device, such as an injector or other delivery system. Medical products containing a combination of new drugs, biological products or medical devices are regulated as “combination products” in the United States. A combination product generally is defined as a product comprised of components from two or more regulatory categories (e.g., drug/device, device/biologic, drug/biologic). Each component of a combination product is subject to the requirements established by the FDA for that type of component, whether a new drug, biologic or device. In order to facilitate pre-market review of combination products, the FDA designates one of its centers to have primary jurisdiction for the pre-market review and regulation of the overall product based upon a determination by the FDA of the primary mode of action of the combination product. The determination whether a product is a combination product or two separate products is made by the FDA on a case-by-case basis. Our product candidates intended for use with such devices, or expanded indications that we may seek for our products used with such devices, may not be approved or may be substantially delayed in receiving approval if the devices do not gain and/or maintain their own regulatory approvals or clearances. Where approval of the drug product and device is sought under a single application, the increased complexity of the review process may delay approval. In addition, because these drug delivery devices are provided by single source unaffiliated third-party companies, we are dependent on the sustained cooperation and effort of those third-party companies both to supply the devices, maintain their own regulatory compliance, and, in some cases, to conduct the studies required for approval or other regulatory clearance of the devices. We are also dependent on those third-party companies continuing to maintain such approvals or clearances once they have been received. Failure of third-party companies to supply the devices, to successfully complete studies on the devices in a timely manner, or to obtain or maintain required approvals or clearances of the devices, and maintain compliance with all regulatory requirements, could result in increased development costs, delays in or failure to obtain regulatory approval and delays in product candidates reaching the market or in gaining approval or clearance for expanded labels for new indications.

Upon approval, a product candidate may be marketed only in those dosage forms and for those indications approved by the FDA. Once approved, the FDA may withdraw the product approval if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the marketplace. In addition, the FDA may require post-marketing studies, referred to as Phase 4 studies, to monitor the approved products in a specific subset of patients or a larger number of patients than were required for product approval and may limit further marketing of the product based on the results of these post-market studies. The FDA has broad post-market regulatory and enforcement powers,


8


including the ability to seek injunctions, levy fines and civil penalties, criminal prosecution, withdraw approvals and seize products or request recalls.


 

TABLE OF CONTENTS

If regulatory approval of any of our product candidates is granted, it will be limited to certain disease states or conditions.conditions, patient populations, duration or frequency of use, and will be subject to other conditions as set forth in the FDA-approved labeling. Adverse experiences with the product must be reported to the FDA and could result in the imposition of market restriction through labeling changes or in product removal. Product approvals may be withdrawn if compliance with regulatory requirements is not maintained or if problems concerning safety or efficacy of the product occur following approval.

Outside the United States, our ability to market our product candidates will also depend on receiving marketing authorizations from the appropriate regulatory authorities. The foreign regulatory approval process generally includes all of the risks associated with FDA approval described above. The requirements governing the conduct of clinical trials and marketing authorization vary widely from country to country. At present, foreign marketing authorizations are applied for at a national level, although within the European Community, or EC, registration procedures are available to companies wishing to market a product to more than one EC member state. If the regulatory authority is satisfied that adequate evidence of safety, quality and efficiency has been presented, a marketing authorizatio nauthorization will be granted.

If any approved product doeswe do not achieve market acceptance, our business will suffer.
Regulatory approval for theobtain, or experience difficulties in obtaining, such marketing and sale of any of our product candidates does not assure the product’s commercial success. Any approved product will compete with other products manufactured and marketed by major pharmaceutical and other biotechnology companies. The degree of market acceptance of any such product will depend on a number of factors, including:
·perceptions by members of the healthcare community, including physicians, about its safety and effectiveness;
·cost-effectiveness relative to competing products and technologies;
·availability of reimbursement for our products from third party payors such as health insurers, health maintenance organizations and government programs such as Medicare and Medicaid; and
·advantages over alternative treatment methods.
If any approved product does not achieve adequate market acceptance,authorizations, our business, financial condition and results of operations willmay be materially adversely affected.
We rely on third parties

Legislative or regulatory healthcare reforms in the United States may make it more difficult and costly for us to conduct clinical trialsobtain regulatory clearance or approval of bremelanotide for ourFSD or any future product candidates and their failure to timely perform their obligationsproduce, market and distribute our products after clearance or approval is obtained.

From time to time, legislation is drafted and introduced in Congress, and court decisions are issued, that could significantly harm our product development.

We rely on outside scientific collaborators such as researchers at clinical research organizationschange the statutory provisions governing the regulatory clearance or approval, manufacture and universities in certain areas thatmarketing of regulated products or the reimbursement thereof. In addition, FDA regulations and guidance are particularly relevant to our research and product development plans, such as the conduct of clinical trials and non-clinical tests. There is competition for these relationships, and we may not be able to maintain our relationships with them on acceptable terms. These outside collaborators generally may terminate their engagements with us at any time. As a result, we can control their activities only within certain limits, and they will devote only a certain amount of their time to conduct research on our product candidates and develop them. If they do not successfully carry out their duties under their agreements with us, fail to inform us if these tr ials fail to comply with clinical trial protocolsoften revised or fail to meet expected deadlines, our ability to develop our product candidates and obtain regulatory approval on a timely basis, if at all, may be adversely affected.
Production and supply of our product candidates depend on contract manufacturers over whom we have no control.
We do not have the facilities to manufacture bremelanotide, PL-3994, melanocortin receptor agonist compounds or our other potential products. Our contract manufacturers must perform these manufacturing activities in a manner that complies with FDA regulations. Our ability to control third-party compliance with FDA requirements will be limited to contractual remedies and rights of inspection. The manufacturers of approved products and their manufacturing facilities will be subject to continual review and periodic inspectionsreinterpreted by the FDA in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of bremelanotide for FSD or any future product candidates. We cannot determine what effect changes in regulations, statutes, court decisions, legal interpretation or policies, when and if promulgated, enacted, issued or adopted may have on our business in the future. Such changes could, among other authorities where applicable, and must comply with ongoing regulatory requirements, including the FDA’s current goodthings:

require changes to manufacturing practices (GMPs) regulations. Failuremethods;
require recall, replacement or discontinuance of third-party manufacturers to comply with GMPs or other FDA requirements may result in enforcement action by the FDA. Failure to conduct their activities in compliance with FDA regulations could delay our development programs or negatively impact our ability to receive

9


FDA approval of our potential products or continue marketing if they are approved. Establishing relationships with new suppliers, who must be FDA-approved, is a time-consuming and costly process.
We are subject to extensive regulation in connection with the laboratory practices and the hazardous materials we use.
We are subject to various laws and regulations regarding laboratory practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances in connection with our research. In each of these areas, as noted above, the FDA and other regulatory authorities have broad regulatory and enforcement powers, including the ability to levy fines and civil penalties, suspend or delay issuance of approvals, seize or recall products and withdraw approvals, any one or more of our products;
require additional recordkeeping;
limit or restrict our ability to engage in certain types of marketing or promotional activities;
alter or eliminate the scope or terms of any currently available regulatory exclusivities; and
restrict or eliminate our ability to settle any patent litigation we may bring against potential generic competitors.

Each of these would likely entail substantial time and cost and could materially harm our business and our financial results. In addition, delays in receipt of or failure to receive regulatory clearances or approvals for any future products would harm our business, financial condition and results of operations.

Changes in healthcare policy could adversely affect our business.

U.S. and foreign governments continue to propose and pass legislation designed to reduce the cost of healthcare. For example, the Medicare Prescription Drug Improvement and Modernization Act of 2003, or MMA, expanded Medicare coverage for drugs purchased by Medicare beneficiaries and introduced new reimbursement methodologies. In addition, this law provided authority for limiting the number of drugs that will be covered in any therapeutic class. We do not know what impact the MMA and similar laws will have on the availability of coverage for and the price that we receive for any approved products. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payers often follow Medicare policies in setting their own reimbursement policies, and any reduction in reimbursement that results from the MMA may result in similar reductions by private payers.


TABLE OF CONTENTS

In March 2010, the President signed the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, together the Affordable Care Act or ACA. This law is expected to result in an increase in the number of people who are covered by both public and private insurance and is also expected to substantially change the way health care is financed by both government health program and private insurers, and significantly impact the pharmaceutical industry. The ACA contains a number of provisions that may impact our business and operations in ways that may negatively affect our potential revenues in the future. For example, the ACA imposes a non-deductible excise tax on pharmaceutical manufacturers or importers that sell branded prescription drugs to U.S. government programs which we believe will increase the cost of any products that we develop. Moreover, the ACA established a 2.3% medical device excise tax on certain transactions, including many United States sales of medical devices, which currently includes, and we expect will continue to include, United States sales of drug/device combination products. In addition, as part of the ACA’s provisions closing a funding gap that currently exists in the Medicare Part D prescription drug program (commonly known as the “donut hole”), we will be required to provide a 50% discount on any branded prescription drugs that we develop sold to beneficiaries who fall within the donut hole. While it is too early to predict all of the specific effects the ACA or any future healthcare reform legislation will have on our business, they could have a material adverse effect on us. We areour business and financial condition.

The availability of government reimbursement for prescription drugs is also subjectlikely to numerous federal, state and local laws relatingbe impacted by the Budget Control Act of 2011, which was signed into law on August 2, 2011. This law is expected to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous subs tances. Even though we have suspended research and development efforts on new product candidates, we are maintaining selected laboratory capabilities, and will be subject to regulations in connection with decommissioning animal facilities, disposal of chemicals and hazardous or potentially hazardous substances, and decommissioning and disposing of laboratory equipment. We may incur significant costs to comply with such laws and regulations now or in the future.

Contamination or injury from hazardous materials used in the development of our products could result in a liability exceeding our financial resources.
Our researchfederal spending cuts totaling between $1.2 trillion and development has involved$1.5 trillion over the usenext decade over half of hazardous materials and chemicals, including radioactive compounds. We cannot completely eliminate the risk of contamination or injury from these materials. In the event of contamination or injury, we may be responsible for any resulting damages. Damages could be significant and could exceed our financial resources, including the limits of our insurance.
We have no experience in marketing, distributing and selling products and will substantially rely on our marketing partners to provide these capabilities.
We are developing bremelanotide and melanocortin receptor agonist compounds for sexual dysfunction and PL-3994 for the treatment of asthma, heart failure and related indications. We do not have marketing partners for any of these products. If any of these products are approved by the FDA or other regulatory authorities, we must either develop marketing, distribution and selling capacity and expertise, which will be costly and time consuming, or enter into agreements with other companies to provide these capabilities. We may not be able to enter into suitable agreements on acceptable terms, if at all.
We do not control the development of compounds licensed to third parties and, as a result, we may not realize a significant portion of the potential value of any such license arrangements.
Under our research collaboration and license agreement with AstraZeneca for our melanocortin-based therapeutic compounds for obesity, diabetes and related metabolic syndrome, we have no direct control over the development of compounds and have only limited, if any, input on the direction of development efforts. If the results of development efforts are negative or inconclusive, AstraZeneca may decide to abandon further development of this program, including terminating the agreement, by giving us notice of termination. Because much of the potential value of the license arrangement with AstraZeneca is contingent upon the successful development and commercialization of the licensed technology, the ultimate value of this license will depend on the efforts of AstraZeneca. If AstraZeneca does no t succeedinclude cuts in developing the licensed technology for any reason, or elects to discontinue the development of this program, we may be unable to realize the potential value of this arrangement.
Competing products and technologies may make our proposed products noncompetitive.
There are a number of other products being developed for FSD and ED. In addition to three oral FDA-approved phosphodiesterase-5 (PDE-5) inhibitor drugs for the treatment of ED, there are other approved products and devices,Medicare and other products are being developed and are in clinical trials. There is competitionhealth related spending.

Risks Related to develop drugs for ED in patients non-responsive to PDE-5 inhibitor drugs, and to develop drugs for treatment of FSD.

There are a large number of products approved for use in asthma, and a number of other products being developed for treatment of acute exacerbations of asthma, including products in clinical trials. There is intense competition to develop drugs for treatment of acute exacerbations of asthma.
We are aware of one recombinant natriuretic peptide product for acutely decompensated congestive heart failure approved and marketed in the United States, and another recombinant natriuretic peptide product approved

10


and marketed in Japan. Clinical trials on other natriuretic peptide products are being conducted in the United States. In addition, other products for treatment of heart failure are either currently being marketed or in development.
The biopharmaceutical industry is highly competitive. We are likely to encounter significant competition with respect to bremelanotide, other melanocortin receptor agonist compounds and PL-3994. Most of our competitors have substantially greater financial and technological resources than we do. Many of them also have significantly greater experience in research and development, marketing, distribution and sales than we do. Accordingly, our competitors may succeed in developing, marketing, distributing and selling products and underlying technologies more rapidly than we can. These competitive products or technologies may be more effective and useful or less costly than bremelanotide, other melanocortin receptor agonist compounds or PL-3994. In addition, academic institutions, hospitals, gov ernmental agencies and other public and private research organizations are also conducting research and may develop competing products or technologies on their own or through strategic alliances or collaborative arrangements.
Our ability to achieve revenues from the sale of our products in development will depend, in part, on our ability to obtain adequate reimbursement from Medicare, Medicaid, private insurers and other healthcare payers.
Our ability to successfully commercialize our products in development will depend, in significant part, on the extent to which we or our marketing partners can obtain reimbursement for our products and also reimbursement at appropriate levels for the cost of our products and related treatment. Obtaining reimbursement from governmental payers, insurance companies, health maintenance organizations (HMOs) and other third-party payers of healthcare costs is a time-consuming and expensive process. There is no guarantee that our products will ultimately be reimbursed. If we are able to obtain reimbursement, continuing efforts by governmental and third party payers to contain or reduce costs of healthcare may adversely affect our future revenues and ability to achieve profitability. Third-party pa yers are increasingly challenging the prices charged for diagnostic and therapeutic products and related services. Reimbursement from governmental payers is subject to statutory and regulatory changes, retroactive rate adjustments, administrative rulings and other policy changes, all of which could materially decrease the range of products for which we are reimbursed or the rates of reimbursement by government payers. In addition, recent legislation reforming the healthcare system may result in lower prices or the actual inability of prospective customers to purchase our products in development. The cost containment measures that healthcare payers and providers are instituting and the effect of any healthcare reform could materially and adversely affect our ability to operate profitably. Furthermore, even if reimbursement is available, it may not be available at price levels sufficient for us to realize a positive return on our investment.
Intellectual Property

If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of others, the value of our intellectual property rights would diminish.

Our success, competitive position and future revenues will depend in part on our ability and the abilities of our licensors to obtain and maintain patent protection for our products, methods, processes and other technologies, to preserve our trade secrets, to prevent third parties from infringing on our proprietary rights and to operate without infringing the proprietary rights of third parties. We cannot predict:

the degree and range of protection any patents will afford us against competitors, including whether third parties will find ways to invalidate or otherwise circumvent our patents;
if and when patents will be issued;
·the degreewhether or not others will obtain patents claiming aspects similar to those covered by our patents and patent applications; and range of protection any patents will afford us against competitors, including whether third parties will find ways to invalidate or otherwise circumvent our patents;
whether we will need to initiate litigation or administrative proceedings, which may be costly whether we win or lose.
·if and when patents will be issued;
·whether or not others will obtain patents claiming aspects similar to those covered by our patents and patent applications; and
·whether we will need to initiate litigation or administrative proceedings, which may be costly whether we win or lose.

If our products, methods, processes and other technologies infringe the proprietary rights of other parties we could incur substantial costs and we may have to:

obtain licenses, which may not be available on commercially reasonable terms, if at all;
redesign our products or processes to avoid infringement;
stop using the subject matter claimed in the patents held by others;
pay damages; or
defend litigation or administrative proceedings, which may be costly whether we win or lose, and which could result in a substantial diversion of our management resources.

 
·obtain licenses, which may not be available on commercially reasonable terms, if at all;

TABLE OF CONTENTS

We may become involved in lawsuits to protect or enforce our patents or other intellectual property or the patents of our licensors, which could be expensive and time consuming.

Competitors may infringe our intellectual property, including our patents or the patents of our licensors. As a result, we may be required to file infringement claims to stop third-party infringement or unauthorized use. This can be expensive, particularly for a company of our size, and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent claims do not cover its technology or that the factors necessary to grant an injunction against an infringer are not satisfied.

An adverse determination of any litigation or other proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Interference, derivation or other proceedings brought at the United States Patent and Trademark Office, or USPTO, may be necessary to determine the priority or patentability of inventions with respect to our patent applications or those of our licensors or collaborators. Litigation or USPTO proceedings brought by us may fail or may be invoked against us by third parties. Even if we are successful, domestic or foreign litigation or USPTO or foreign patent office proceedings may result in substantial costs and distraction to our management. We may not be able, alone or with our licensors or collaborators, to prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other proceedings, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or proceedings. In addition, during the course of this kind of litigation or proceedings, there could be public announcements of the results of hearings, motions or other interim proceedings or developments or public access to related documents. If investors perceive these results to be negative, the market price for our common stock could be significantly harmed.

If we infringe or are alleged to infringe intellectual property rights of third parties, our business could be harmed.

Our research, development and commercialization activities may infringe or otherwise violate or be claimed to infringe or otherwise violate patents owned or controlled by other parties. There may also be patent applications that have been filed but not published that, when issued as patents, could be asserted against us. These third parties could bring claims against us that would cause us to incur substantial expenses and, if successful against us, could cause us to pay substantial damages. Further, if a patent infringement suit were brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of the suit.

As a result of patent infringement claims, or to avoid potential claims, we may choose or be required to seek licenses from third parties. These licenses may not be available on acceptable terms, or at all. Even if we are able to obtain a license, the license would likely obligate us to pay license fees or royalties or both, and the rights granted to us might be nonexclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms, if at all.

There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical industry. In addition to infringement claims against us, we may become a party to other patent litigation and other proceedings, including interference, derivation or post-grant proceedings declared or granted by the USPTO and similar proceedings in foreign countries, regarding intellectual property rights with respect to our current or future products. The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Patent litigation and other proceedings may also absorb significant management time. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could


 
·redesign our products or processes to avoid infringement;
·stop using the subject matter claimed in the patents held by others;
·pay damages; or

11


·defend litigation or administrative proceedings, which may be costly whether we win or lose, and which could result in a substantial diversion of our management resources.

TABLE OF CONTENTS

impair our ability to compete in the marketplace. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition or results of operations.

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

Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States and in some cases may even force us to grant a compulsory license to competitors or other third parties. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

In addition, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in domestic and foreign intellectual property laws.

If we are unable to keep our trade secrets confidential, our technologies and other proprietary information may be used by others to compete against us.

In addition to our reliance on patents, we attempt to protect our proprietary technologies and processes by relying on trade secret laws and agreements with our employees and other persons who have access to our proprietary information. These agreements and arrangements may not provide meaningful protection for our proprietary technologies and processes in the event of unauthorized use or disclosure of such information. In addition, our competitors may independently develop substantially equivalent technologies and processes or gain access to our trade secrets or technology, either of which could materially and adversely affect our competitive position.

Risks Relating to Obligations in Our 2012 Private Placement

Under agreements relating to our 2012 private placement, we are required to allow purchasers in the 2012 private placement to participate in certain future equity and debt financings, which may restrict our ability to raise funds on acceptable terms, or at all.

For six years after our 2012 private placement, unless the purchasers own less than 20% of our outstanding common stock calculated as if the warrants were exercised, the purchasers have the right of first negotiation on any subsequent equity or debt financing. If we do not agree to terms of a financing with them, and negotiate with a third party on a financing, we must offer to sell to the purchasers at least 55% of the financing, and the purchasers may elect to purchase all or a portion of the financing. We expect that the purchasers will agree to waive their right of first negotiation and right of participation, along with other rights granted to them in the transaction documents for the 2012 private placement, prior to the closing of this

offering. We will require significant additional resources and capital for our Phase 3 bremelanotide clinical trial program and other clinical trial programs. The right of first negotiation and right of participation granted to the purchasers in our 2012 private placement may incur substantial liabilitiesmake it more difficult to raise additional funding through public or private equity or debt financings or other sources. Such funding may not be available on acceptable terms, or at all.

Under agreements relating to our 2012 private placement, so long as any Series A 2012 or Series B 2012 warrants are outstanding, we are required to redeem Series A 2012 and Series B 2012 warrants at the option of the holders in the event of any takeover, change of control or other fundamental transaction which we permit.

Under the purchase agreement and form of warrants for our 2012 private placement, if we permit, make or allow a takeover, change of control or other fundamental transaction, including any transfer of all or substantially all of our properties or assets, then so long as any warrants remain outstanding we are required, as elected by the warrant holders, to pay such holders a warrant early termination price tied to the greater of the then market price of our common stock or the amount per share paid to any other person. The application of these provisions could adversely affect our financial position and have the effect of delaying or preventing a change of control or other fundamental transaction, which could adversely affect the market price of our common stock, and could make any potential acquisition or change of control more costly.

Under agreements relating to our 2012 private placement, so long as any Series A 2012 or Series B 2012 warrants are outstanding, we are required to oppose any takeover or change of control that does not provide specified rights to holders of Series A 2012 and Series B 2012 warrants.

Under the purchase agreement and form of warrants for our 2012 private placement, so long as any warrants remain outstanding we are required to (i) not permit, (ii) take necessary action to prevent both the occurrence or consummation of, and (iii) not be a party to any fundamental transaction, change of control or similar event unless contractually-specified rights are provided with respect to payment of a warrant early termination price tied to the greater of the then market price of our common stock or the amount per share paid to any other person.

We are also required, subject to the exercise by our board of its fiduciary duties, to take all reasonable efforts to adopt a poison pill or any other anti-takeover provision or method necessary to prevent the fundamental transaction, change of control or similar event. The application of these provisions could have the effect of delaying or preventing a change of control or other fundamental transaction, which could adversely affect the market price of our common stock, and could make any potential acquisition or change of control more costly.

Risks Related to this Offering and the Ownership of Our Securities

Our stock price is volatile and may be requiredfluctuate in a way that is disproportionate to our operating performance and we expect it to remain volatile, which could limit commercializationinvestors’ ability to sell stock at a profit.

The volatile price of our stock makes it difficult for investors to predict the value of their investment, to sell shares at a profit at any given time or to plan purchases and sales in advance. A variety of factors may affect the market price of our common stock. These include, but are not limited to:

publicity regarding actual or potential clinical results relating to products under development by our competitors or us;
delay or failure in responseinitiating, completing or analyzing preclinical or clinical trials or unsatisfactory designs or results of these trials;
interim decisions by regulatory agencies, including the FDA, as to product liability lawsuits.clinical trial designs, acceptable safety profiles and the benefit/risk ratio of products under development;

We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance. If we cannot successfully defend ourselves against product liability claims,our revenues, if any, in any particular period do not meet expectations, we may incur substantial liabilitiesnot be able to adjust our expenditures in that period, which could cause our operating results to suffer further. If our operating results in any future period fall below the expectations of securities analysts or be required to limit commercializationinvestors, our stock price may fall by a significant amount.

For the 12-month period ended September 30, 2014, the price of our productsstock has been volatile, ranging from a high of $1.50 per share to a low of $0.56 per share. In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price and volume fluctuations that may have been unrelated or cease clinical trials. Our inabilitydisproportionate to obtain sufficient product liability insurancethe operating performance of individual companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.

Substantial future sales of our shares of common stock in the public market, or the perception that these sales could occur, could cause the price of our common stock to decline.

Additional sales of our common stock in the public market after this offering, or the perception that these sales could occur, could cause the market price of our common stock to decline. Upon completion of this offering, we will have      shares of our common stock outstanding and, if all of the warrants issued in this offering are exercised, we will have      shares of our common stock outstanding. All shares of common stock sold in this offering will be freely transferable without restriction or additional registration under the U.S. Securities Act of 1933, as amended, or the Securities Act. The shares of common stock held by our directors, including our officers, will be available for sale upon expiration of a lock-up period, which we expect will expire 90 days after the date of this prospectus. The remaining shares of common stock will be available for sale after this offering since they are not subject to contractual and legal restrictions on resale. Any or all of these shares may be released prior to expiration of the lock-up period at an acceptable costthe discretion of the underwriters for this offering. To the extent shares are released before the expiration of the lock-up period and these shares are sold into the market, the market price of our common stock could decline.

As a public company in the United States, we are subject to protect against potential product liability claims could preventthe Sarbanes-Oxley Act of 2002, or inhibit the commercialization of pharmaceutical productsSarbanes-Oxley. We can provide no assurance that we develop, alone or with corporate collaborators. We currently carry liability insurance as to certain clinical trial risks. We, or any corporate collaborators, may notwill, at all times, in the future be able to obtain insurancereport that our internal controls over financial reporting are effective.

Companies that file reports with the Securities and Exchange Commission, or the SEC, including us, are subject to the requirements of Section 404 of Sarbanes-Oxley. Section 404 requires management to establish and maintain a system of internal control over financial reporting, and annual reports on Form 10-K filed under the Securities Exchange Act of 1934, as amended, or the Exchange Act, must contain a report from management assessing the effectiveness of a company’s internal control over financial reporting. Ensuring that we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis will be a costly and time-consuming effort that needs to be re-evaluated frequently. Failure on our part to have effective internal financial and accounting controls would cause our financial reporting to be unreliable, could have a material adverse effect on our business, operating results, and financial condition, and could cause the trading price of our common stock to fall dramatically.

If securities or industry analysts do not publish research or publish unfavorable research about our business, our stock price and trading volume could decline.

As a smaller company, it may be difficult for us to attract or retain the interest of equity research analysts. A lack of research coverage may adversely affect the liquidity of and market price of our common stock. We do


TABLE OF CONTENTS

not have any control of the equity research analysts or the content and opinions included in their reports. The price of our stock could decline if one or more equity research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of our company, or fails to publish reports on us regularly, demand for our stock could decrease, which in turn could cause our stock price or trading volume to decline.

Holders of our preferred stock may have interests different from our common stockholders.

We are permitted under our certificate of incorporation to issue up to 10 million shares of preferred stock. We can issue shares of our preferred stock in one or more series and can set the terms of the preferred stock without seeking any further approval from our common stockholders. 4,697 shares of our Series A Preferred Stock remain outstanding as of October 21, 2014. Each share of Series A Preferred Stock is convertible at any time, at the option of the holder, and such conversion could dilute the value of our common stock to current stockholders and could adversely affect the market price of our common stock. The conversion price decreases if we sell common stock (or equivalents) for a reasonable costprice per share less than the conversion price or less than the market price of the common stock and is also subject to adjustment upon the occurrence of a merger, reorganization, consolidation, reclassification, stock dividend or stock split which results in an increase or decrease in the number of shares of common stock outstanding. Upon (i) liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, (ii) sale or other disposition of all or substantially all of the assets of the Company, or (iii) any consolidation, merger, combination, reorganization or other transaction in which the Company is not the surviving entity or in sufficient amounts,which the shares of common stock constituting in excess of 50% of the voting power of the Company are exchanged for or changed into other stock or securities, cash and/or any other property, after payment or provision for payment of the debts and other liabilities of the Company, the holders of Series A Preferred Stock will be entitled to receive, pro rata and in preference to the holders of any other capital stock, an amount per share equal to $100 plus accrued but unpaid dividends, if at all. Evenany. Any preferred stock that we issue may rank ahead of our common stock in terms of dividend priority or liquidation premiums and may have greater voting rights than our common stock.

Anti-takeover provisions of Delaware law and our charter documents may make potential acquisitions more difficult and could result in the entrenchment of management.

We are incorporated in Delaware. Anti-takeover provisions of Delaware law and our charter documents may make a change in control or efforts to remove management more difficult. Also, under Delaware law, our board of directors may adopt additional anti-takeover measures. Under Section 203 of the Delaware General Corporation Law, a corporation may not engage in a business combination with an “interested stockholder” for a period of three years after the date of the transaction in which the person first becomes an “interested stockholder,” unless the business combination is approved in a prescribed manner.

We are authorized to approvals by our stockholders atissue up to 300,000,000 shares of common stock. To the annual meeting of stockholders held on May 13, 2010, effective July 23, 2010extent that we increased oursell or otherwise issue authorized common stock from 150,000,000 to 400,000,000, and on September 27, 2010 we implemented a one-for-ten reverse stock split, which reduced our authorized common stock to 40,000,000 shares. Thisbut currently unissued shares, this could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock.

Our charter authorizes us to issue up to 10,000,000 shares of preferred stock and to determine the terms of those shares of stock without any further action by our stockholders. If we exercise this right, it could be more difficult for a third party to acquire a majority of our outstanding voting stock.

In addition, our equity incentive plans generally permit us to accelerate the vesting of options and other stock rights granted under these plans in the event of a change of control. If we accelerate the vesting of options or other stock rights, this action could make an acquisition more costly.

The application of these provisions could have the effect of delaying or preventing a change of control, which could adversely affect the market price of our common stock.

Risks Relating to Owning our Common Stock
Our stock price is volatile and we expect it to remain volatile, which could limit investors’ ability to sell stock at a profit.
The volatile price of our stock makes it difficult for investors to predict the value of their investment, to sell shares at a profit at any given time, or to plan purchases and sales in advance. A variety of factors may affect the market price of our common stock. These include, but are not limited to:
·publicity regarding actual or potential clinical results relating to products under development by our competitors or us;
·delay or failure in initiating, completing or analyzing preclinical or clinical trials or unsatisfactory designs or results of these trials;
·interim decisions by regulatory agencies, including the FDA, as to clinical trial designs, acceptable safety profiles and the benefit/risk ratio of products under development;
·achievement or rejection of regulatory approvals by our competitors or by us;
·announcements of technological innovations or new commercial products by our competitors or by us;
·developments concerning proprietary rights, including patents;
·developments concerning our collaborations;
·regulatory developments in the United States and foreign countries;
·economic or other crises and other external factors;
·period-to-period fluctuations in our revenue and other results of operations;
·changes in financial estimates by securities analysts; and
·sales of our common stock.
We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance. If our revenues, if any, in any particular period do not meet expectations, we may not be able to adjust our expenditures in that period, which could cause our operating results to suffer further. If our operating results in any future period fall below the expectations of securities analysts or investors, our stock price may fall by a significant amount.
For the 12 month period ended September 30, 2010, the price of our stock has been volatile, ranging from a high of $4.40 per share to a low of $1.26 per share.
In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price and volume fluctuations that may have been unrelated or disproportionate to the operating performance of individual companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.
We have implemented a reverse stock split, which has reduced our trading volume and may result in a decrease in our market capitalization.
Effective September 27, 2010, we implemented a one-for-ten reverse stock split. This reverse stock split was implemented because we had received notice that the NYSE Amex deemed it appropriate for us to effect a reverse stock split because of the low selling price of our common stock. At our annual meeting of stockholders held on May 13, 2010, the stockholders authorized a reverse stock split. We cannot guarantee that the price increase of our common stock price resulting from the reverse split will:
·be proportionate to the reverse split ratio;

13


·last in the marketplace for any length of time;
·remain at a price sufficient to meet the listing requirements of the NYSE Amex; or
·be sufficient to facilitate raising capital.
Our stock has previously been subject to delisting proceedings on NYSE Amex and could be subject to such proceedings in the future.
Our common stock trades on NYSE Amex. In December 2008 we received notice from NYSE Amex that we did not meet continued listing standards based on minimum stockholders’ equity requirements. While we have cured those deficiencies, it is possible that we could fall out of compliance again in the future. If we fail to maintain compliance with continued listing standards, then we could be delisted from NYSE Amex. If we are delisted from NYSE Amex then our common stock will trade, if at all, only on the over-the-counter market, and then only if one or more registered broker-dealer market makers comply with quotation requirements. Delisting of our common stock could also further depress our stock price, substantially limit liquidity of our common stock and materially adversely affect our ab ility to raise capital on terms acceptable to us, or at all. Delisting from NYSE Amex could also have other negative results, including the potential loss of confidence by suppliers and employees, the loss of institutional investor interest and fewer business development opportunities.
We do not intend to pay cash dividends in the foreseeable future.
We do not anticipate paying any cash dividends in the foreseeable future and intend to retain future earnings, if any, for the development and expansion of our business. In addition, the terms of existing or future agreements may limit our ability to pay dividends. Therefore, our stockholders will not receive a return on their shares unless the value of their shares increases.
Risks Related to this Offering
You will experience immediate and substantial dilution as a result of this offering.
As of June 30, 2010, we had a net tangible book value of $9.3 million which yields a net tangible book value of approximately $0.79 per share of common stock, assuming the conversion of all then convertible preferred stock and no exercise of any warrants or options. The net tangible book value per share is less than the current market price per share. If you pay more than the net tangible book value per share for stock in this offering, you will experience immediate dilution.

As of October 28, 2010,21, 2014, there were 2,588,11496,380,173 shares of common stock underlying outstanding convertible preferred stock, options, warrants and restricted stock units and youwarrants. Stockholders may experience dilution from the conversion of preferred stock, exercise of outstanding options and warrants and the vesting of restricted stock units.

As of October 28, 2010,21, 2014, holders of our outstanding dilutive securities had the right to acquire the following amounts of underlying common stock:

52,829 shares of common stock reserved for issuance upon any conversion of our Series A Convertible Preferred Stock outstanding as of October 21, 2014;
4,229,913 shares issuable on the exercise of stock options, at exercise prices ranging from $0.60 to $37.50 per share;
·26,865 shares issuable on the conversion of immediately convertible Series A Convertible preferred stock, subject to adjustment, for no further consideration;
845,900 shares issuable under restricted stock units which vest on dates between June 25, 2015 and June 25, 2018, subject to the fulfillment of service conditions; and
91,251,531 shares issuable on the exercise of warrants at exercise prices ranging from $0.01 to $1.50 per share outstanding as of October 21, 2014.
·1,553,248 shares issuable on the exercise of warrants, at exercise prices ranging from $2.00 to $40.00 per share;
·927,501 shares issuable on the exercise of stock options, at exercise prices ranging from $1.30 to $47.00 per share; and
·80,500 shares issuable under restricted stock units that vest no later than March 15, 2011, subject to the fulfillment of service conditions.

If the holders convert, exercise or receive thosethese securities, or similar dilutive securities we may issue in the future, stockholders may experience dilution in the net tangible book value of their common stock. In addition, the sale or availability for sale of the underlying shares in the marketplace could depress our stock price. We have registered or agreed to register for resale substantially all of the underlying shares listed above. Holders of registered underlying shares could resell the shares immediately upon issuance, resultingwhich could result in significant downward pressure on our stock.

Although we currently meet the NYSE MKT’s listing standards, which generally mandate that we meet certain requirements relating to stockholders’ equity, market capitalization, aggregate market value of publicly held shares and distribution requirements, we cannot assure you that we will be able to continue to meet the NYSE MKT’s listing requirements. If we fail to satisfy the continued listing requirements of the NYSE MKT, such as the corporate governance requirements or the minimum closing bid price requirement, the NYSE MKT may not realize take steps to de-list our common stock. If the NYSE MKT delists our securities for trading on its exchange, we could face significant material adverse consequences, including:

a return.limited availability of market quotations for our securities;
reduced liquidity with respect to our securities;

DILUTION

If you invest in our securities, your ownership interest will be diluted immediately to the extent of the difference between the public offering price per unit and the as adjusted net book value per share of our common stock upon closing of this offering. Our historical net book value as of June 30, 2014, was approximately $9.8 million, or $0.25 per share of outstanding common stock, based on shares of common stock outstanding as of June 30, 2014. Net book value per share of our common stock is determined at any date by subtracting total liabilities from the amount of total assets, and dividing this amount by the number of shares of common stock deemed to be outstanding as of that date.

After giving effect to the sale by us of      units at a public offering price of $     per unit in connection with this offering, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net book value as of June 30, 2014 would have been approximately $     million, or approximately $     per share of outstanding common stock. This amount represents an immediate increase in net book value of $     per share of our common stock to our existing stockholders and an immediate dilution of $     per share of our common stock to new investors purchasing securities in this offering, as illustrated in the following table:

  
Assumed public offering price per unit      $     
Historical net book value per share as of June 30, 2014 $0.25      
As adjusted increase in net book value per share attributable to new investors in this offering $      
As adjusted net book value per share of our common stock after this offering      $ 
Dilution of as adjusted net book value per share to new investors    $   

Each $0.10 increase (decrease) in the public offering price of $     per unit would increase (decrease) our net book value after giving effect to this offering by approximately $     million, or approximately $     per share, and the dilution per share to new investors by approximately $     per share, assuming that the number of units offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters’ over-allotment option is exercised in full, our as adjusted net book value per share after giving effect to this offering would be $     per share of our common stock, representing an immediate increase in net book value per share to existing stockholders of approximately $     per share, and an immediate dilution in net book value of $     per share of our common stock to new investors in this offering would be $     per share. If any shares of our common stock are issued upon exercise of outstanding options, restricted stock units or warrants or upon conversion of shares of our Series A Preferred Stock, you will experience further dilution.

MANAGEMENT'S

TABLE OF CONTENTS

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION


AND RESULTS OF OPERATIONS
The

You should read the following discussion and analysis should be read in conjunctionof our financial condition and results of operations together with the consolidatedour financial statements and the related notes and other financial information included elsewhere in this prospectus. Some of the information contained in this discussion and analysis or set forth elsewhere in this prospectus, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” section of this prospectus for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a biopharmaceutical company developing targeted, receptor-specific peptide therapeutics for the treatment of diseases with significant unmet medical need and commercial potential. Our programs are based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. Our primary product in clinical development is bremelanotide for the treatment of FSD. In addition, we have drug candidates or development programs for obesity, erectile dysfunction, cardiovascular diseases, pulmonary diseases, inflammatory diseases and dermatologic diseases.

The following drug development programs are actively under development:

Bremelanotide, an on-demand subcutaneous injectable peptide melanocortin receptor agonist, for treatment of FSD in premenopausal women. Bremelanotide, which is a melanocortin agonist, is a synthetic peptide analog of the naturally occurring hormone alpha-MSH. The novel mechanism of action involves activating endogenous melanocortin hormone pathways involved in sexual arousal response. Bremelanotide is scheduled to start Phase 3 clinical trials in the last quarter of calendar 2014;
MC4r compounds for treatment of obesity and diabetes in collaboration with AstraZeneca pursuant to our research collaboration and license agreement. Results of our studies involving MC4r peptides suggest that certain of these peptides may have significant commercial potential for treatment of conditions responsive to MC4r activation, including FSD, ED, obesity and diabetes;
PL-3994, an NPR-A agonist, for treatment of cardiovascular and pulmonary indications. PL-3994 is our lead natriuretic peptide receptor product candidate, and is a synthetic mimetic of the neuropeptide hormone ANP. PL-3994 is in development for treatment of heart failure, acute exacerbations of asthma and refractory hypertension; and
MC1r agonist peptides for treatment of inflammatory and dermatologic disease indications. Our MC1r peptide drug candidates are highly specific, with substantially greater binding and efficacy at MC1r than at other melanocortin receptors. We have selected one of our MC1r peptide drug candidates, designated PL-8177, as a clinical trial candidate.

Key elements of our business strategy include: using our technology and expertise to develop and commercialize innovative therapeutic products; entering into alliances and partnerships with pharmaceutical companies to facilitate the development, manufacture, marketing, sale and distribution of product candidates that we are developing; and partially funding our product development programs with the cash flow generated from research collaboration and license agreements and any potential future agreements with third parties.

At June 30, 2014, we had an accumulated deficit of approximately $274.0 million. We expect to incur substantial operating losses in future periods. We do not expect to generate significant product revenue, sales-based milestones or royalties until we successfully complete development and obtain marketing approval for our product candidates, either alone or in collaborations with third parties, which we expect will take a number of years. In order to commercialize our product candidates, we need to complete clinical development and to comply with comprehensive regulatory requirements.

We believe we have sufficient currently available working capital to fund our planned operations through the quarter ending September 30, 2015, not including initiation of our pivotal Phase 3 clinical trials for


TABLE OF CONTENTS

bremelanotide for FSD or other planned clinical trials. Following this offering, assuming the Phase 3 clinical trials of bremelanotide for FSD are successful, as to which there can be no assurance, we will need additional funding to complete submission of required regulatory applications to the consolidatedFDA for bremelanotide for FSD. We will also need additional funding to complete required clinical trials for our other product candidates and, assuming those clinical trials are successful, as to which there can be no assurance, to complete submission of required regulatory applications to the FDA. It is possible that we will not achieve the progress that we expect with respect to bremelanotide for FSD because the actual costs and timing of clinical development activities are difficult to predict and are subject to substantial risks and delays. Accordingly, we will be required to obtain further funding through public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. Financing may not be available to us in the necessary timeframe, in the amounts that we need, on terms acceptable to us, or at all. Our failure to raise capital as and when needed would have a negative impact on our financial statements filed as part of this prospectus.

condition and our ability to pursue our business strategy.

Critical Accounting Policies.

Policies and Estimates

Our significant accounting policies are described in Note 2 to the consolidated financial statements included in this prospectus. We believe that our accounting policies and estimates relating to revenue recognition, accrued expenses and stock-based compensation charges are the most critical.

Revenue Recognition

Revenue from corporate collaborations and licensing agreements consists of up-front fees, research and development funding and milestone payments. Non-refundable up-front fees are deferred and amortized to revenue on a straight-line basis over the related performance period. We estimate the performance period as the period in which we perform certain development activities under the applicable agreement. Reimbursements for research and development activities are recorded in the period that we perform the related activities under the terms of the applicable agreements. Revenue resulting from the achievement of milestone events stipulated in the applicable agreements is recognized when the milestone is achieved, provided that such milestone is substantive in nature.

The $10.0 million upfront payment received in January 2007 under the research collaboration and license agreement with AstraZeneca and the additional $5.0 million received pursuant to the September 2009 amendment has been recognized as revenue over the period ended January 2010, the completion of the research collaboration portion of the agreement.
In 2004, we entered into a collaborative development and marketing agreement with King Pharmaceuticals, Inc. (King) to jointly develop and commercialize bremelanotide, which agreement was terminated effective December 2007. Deferred revenue related to the King agreement had been recognized as revenue over the estimated period of our performance during the initial development term of this agreement. In connection with the termination of the agreement, we recognized as revenue in our fiscal year ended June 30, 2008 all remaining deferred up-front license fees received from King, together with associated deferred costs, in the amounts of $6.5 million and $0.8 million, respectively.

Accrued Expenses

Third parties perform a significant portion of our development activities. We review the activities performed under significant contracts each quarter and accrue expenses and the amount of any reimbursement to be received from our collaborators based upon the estimated amount of work completed. Estimating the value or stage of completion of certain services requires judgment based on available information. If we do not identify services performed for us but not billed by the service-provider, or if we underestimate or overestimate the value of services performed as of a given date, reported expenses will be understated or overstated.

Stock-based Compensation

The fair value of stock options granted has been calculated using the Black-Scholes option pricing model, which requires us to make estimates of expected volatility and expected option lives. We estimate these factors at the time of grant based on our own prior experience, public sources of information and information for comparable companies. The amount of recorded compensation related to an option grant is not adjusted for subsequent changes in these estimates or for actual experience. The amount of our recorded compensation is also dependent on our estimates of future option forfeitures and the probability of achievement of performance conditions.forfeitures. If we initially over-estimate future forfeitures, our reported expenses will be understated until such time as we adjust our estimate. Changes in estimated forfeitures will affect our reported expenses in the period of change and future periods.

The amount and timing of compensation expense to be recorded in future periods related to grants of restricted stock units may be affected by employment terminations. As a result, stock-based compensation charges may vary significantly from period to period.

Preferred Stock and Warrants

As of June 30, 2014, 4,697 shares of Series A Convertible Preferred Stock were outstanding. Each share of Series A Convertible Preferred Stock is convertible at any time, at the option of the holder, into the number of shares of common stock equal to $100 divided by the Series A Conversion Price, which, as of June 30, 2014, was $8.89, so each share of Series A Convertible Preferred Stock was convertible into approximately

11.25 shares of common stock. In addition, as of June 30, 2014, the Company had outstanding warrants exercisable for 91,583,500 shares of common stock.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update, or ASU, No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us on July 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet determined the effect of the standard on our ongoing financial reporting.

2013:

Revenue — For the fiscal year ended June 30, 20102014 (fiscal 2010)2014), we recognized $14.2 million inno revenue, compared to $11.4 million$10,000 for the fiscal year ended June 30, 20092013 (fiscal 2009)2013), pursuant to our research collaboration and license agreement with AstraZeneca.

Revenue from AstraZeneca for fiscal 2010 and fiscal 2009 consists of $3.2 million and $9.7 million, respectively, of revenue related to our research services performed during those periods, and $11.0 million and $1.7 million, respectively, of revenue related to AstraZeneca’s up-front license fee. In connection with the completion of the research collaboration portion of the research collaboration and license agreement, we recognized as revenue in fiscal 2010 all remaining deferred up-front license fees received from AstraZeneca. Future contract revenue from AstraZeneca, in the formconsisted entirely of reimbursement of development costs will fluctuate based on development activities in our obesity program. We may also earn contract revenue based onand per-employee compensation, earned at the attainment of development milestones.

Research and Development — Research and development expenses decreased to $12.3were $10.8 million for fiscal 20102014 compared to $13.4$10.5 million for fiscal 2009. The decrease is the result of the restructuring of our clinical-stage product portfolio and development programs.

2013. Research and development expenses related to our bremelanotide, otherPL-3994, peptide melanocortin receptor agonists, PL-3994,agonist, obesity and other preclinical programs were $4.1$7.9 million and $7.6 million in each of fiscal years 20102014 and 2009. Spending to date has been2013, respectively. The spending was primarily related to the identification and optimizationpreparation costs of lead compounds,our Phase 3 studies of bremelanotide for the treatment of FSD and secondarily to study the effects of melanocortin receptor-specific compounds on food intake, obesitycosts related to our other preclinical and other metabolic parameters and preclinical studies and a Phase 1 trial with subcutaneously administered bremelanotide.development programs. The amount of such spending and the nature of future development activities are dependent on a number of factors, including primarily the availability of funds to support future development activities, success of our clinical trials and preclinical and discovery programs, and our ability to progress compounds i nin addition to bremelanotide and PL-3994 into human clinical trials.
The historical amounts of project spending above exclude general research and development spending, which decreased to $8.2were $2.9 million for fiscal 2010 compared to $9.3 million for2014 and fiscal 2009. The decrease is primarily related to management’s refinement of operations and expense control.
2013, respectively.

Cumulative spending from inception to June 30, 20102014 on our bremelanotide, NeutroSpec (a previously marketed imaging product on which all work is suspended)has been terminated) and other programs (which includeincludes PL-3994, PL-8177, other melanocortin receptor agonists, obesity and other discovery programs) amounts to $133.2approximately $170.9 million, $55.5$55.6 million and $56.8 million, respectively. Due to various risk factors described in this prospectus, including the difficulty in currently estimating the costs and timing of future Phase 1 clinical trials and larger-scale Phase 2 and Phase 3 clinical trials for any product under development, we cannot predict with reasonable certainty when, if ever, a program will advance to the next stage of development or be successfully completed, or when, if ever, related net cash inflows will be genera ted. See the section entitled “Risk Factors.”

General and Administrative – General and administrative expenses decreased to $4.9 million for fiscal 2010 compared to $5.3 million for fiscal 2009. The decrease is primarily related to management’s refinement of operations and expense control.
Income Tax Benefit – Income tax benefits of $1.0 million in fiscal 2010 and $1.7 million in fiscal 2009 relate to the sale of New Jersey state net operating loss carryforwards. The amount of such losses and tax credits that we are able to sell depends on annual pools and allocations established by the state of New Jersey.
Year Ended June 30, 2009 Compared to the Year Ended June 30, 2008:
Revenue – For fiscal 2009, we recognized $11.4 million in revenue compared to $11.5 million for the fiscal year ended June 30, 2008 (fiscal 2008). Revenue consisted of the following:
Fiscal 2009Fiscal 2008Revenue related to:

-$0.3 million
NeutroSpec, pursuant to our collaboration agreement with Mallinckrodt.
Revenue from AstraZeneca for fiscal 2009 and fiscal 2008 consists of $9.7 million and $1.3 million, respectively, of revenue related to our research services performed during those periods, and $1.7 million and $1.7

21


million, respectively, of revenue related to AstraZeneca’s up-front license fee. As discussed under “Revenue Recognition” above, in fiscal 2008 we recognized remaining deferred up-front license fees and associated deferred costs on termination of our collaboration agreement with King. Contract revenue from Mallinckrodt, with whom we have a strategic collaboration agreement to develop NeutroSpec, primarily reflects Mallinckrodt’s share of the costs incurred in NeutroSpec development activities. There were no substantive development activities on NeutroSpec in fiscal 2009 or fiscal 2010, though the agreement with Mallinckrodt has not been terminated.
Research and Development – Research and development expenses decreased to $13.4 million for fiscal 2009 compared to $21.2 million for fiscal 2008.  The decrease is the result of the restructuring of our clinical-stage product portfolio and development programs and the reduction in workforce initiated in May 2008.
Research and development expenses related to our bremelanotide, other melanocortin receptor agonists, PL-3994, obesity, NeutroSpec and other preclinical programs were $4.1 million for fiscal 2009 and $7.1 million for fiscal 2008. Spending to date has been primarily related to the identification and optimization of lead compounds, and secondarily to a study of the effects of melanocortin receptor-specific compounds on food intake, obesity and other metabolic parameters and preclinical studies, a Phase 1 and a Phase 2A trial with PL-3994 and additional preclinical studies and a Phase 1 trial with subcutaneously administered bremelanotide. The amount of such spending and the nature of future development activities are dependent on a number of factors, including primarily the availability of funds to support future development activities, su ccess of our clinical trial, preclinical and discovery programs, and our ability to progress compounds in addition to bremelanotide and PL-3994 into human clinical trials.
The historical amounts of project spending above exclude general research and development spending, which decreased to $9.3 million for fiscal 2009 compared to $14.1 million for fiscal 2008. The decrease is primarily related to the reduction in workforce initiated in May 2008.
Cumulative spending from inception to June 30, 2009 on our bremelanotide, NeutroSpec and other programs (which includes PL-3994, PL-6983, obesity, and other discovery programs) amounts to approximately $126.8 million, $55.5 million and $51.0$64.5 million, respectively. Due to various risk factors described in this prospectus, including the difficulty in currently estimating the costs and timing of future Phase 1 clinical trials and larger-scale Phase 2 and Phase 3 clinical trials for any product under development, we cannot predict with reasonable certainty when, if ever, a program will advance to the next stage of development or be successfully completed, or when, if ever, related net cash inflows will be generated.

General and Administrative — General and administrative expenses decreased to $5.3were $5.0 million for fiscal 20092014 compared to $6.9$5.1 million for fiscal 2008. The decrease is primarily2013. These expenses mainly consist of compensation and related costs.

Other Income (Expense) — Other income (expense) was $13,000 and $(7.0) million for fiscal 2014 and fiscal 2013, respectively. For fiscal 2014, we recognized $19,000 of investment income compared to $43,000 of investment income for fiscal 2013. Fiscal 2013 other expense included the recognition of $7.1 million non-cash charged for the increase in the fair value of warrants related to the reductionJuly 3, 2012 private placement offering from $0.50 per share at date of issuance to $0.71 per share upon shareholder approval. Because there were not sufficient authorized shares to cover all the outstanding warrants in workforce initiated in May 2008.the private placement offering as of closing, under ASC 815, “Derivatives and Hedging,” the portion of the warrants above the then authorized level of common stock was required to be classified as a liability and carried at fair value on our balance sheet. The fair value was calculated by multiplying the number of shares underlying the warrants above the then authorized level of our common stock by the closing price of our common stock less the exercise price of $0.01 per share. These warrants were liability classified through September 27, 2012, at which time the

then fair value of the warrant liability was reclassified into stockholders’ equity upon stockholder approval of the increase in authorized common stock. There were no warrants required to be liability classified or any changes in fair value of warrants during fiscal 2014.

Income Tax Benefit — Income tax benefits of $1.7$1.8 million in fiscal 20092014 and $1.3 million in fiscal 20082013, respectively, relate to the sale of New Jersey state net operating loss carryforwards. The amount of such losses and tax credits that we are able to sell depends on annual pools and allocations established by the state of New Jersey. This Program enables approved, unprofitable biotechnology businesses to sell their unused Net Operating Loss Carryovers, or NOLs, and unused Research and Development, or R&D, Tax Credits to unaffiliated, profitable corporate taxpayers in the State of New Jersey.

Year Ended June 30, 2013 Compared to the Year Ended June 30, 2012:

Revenue — For the fiscal year ended June 30, 2013 (fiscal 2013), we recognized $10,000 in revenue, compared to $74,000 for the fiscal year ended June 30, 2012 (fiscal 2012), pursuant to our license agreement with AstraZeneca. Revenue consisted entirely of reimbursement of development costs and per-employee compensation, earned at the contractual rate.

Research and Development — Research and development expenses decreased to $10.5 million for fiscal 2013 compared to $13.8 million for fiscal 2012. This decrease was primarily the result of costs relating to our Phase 2B clinical trial evaluating the efficacy and safety of bremelanotide for the treatment of FSD.

Research and development expenses related to our bremelanotide, PL-3994, peptide melanocortin agonist, obesity and other preclinical programs were $7.6 million and $9.9 million in fiscal years 2013 and 2012, respectively. The majority of spending was related to our Phase 2B clinical trial evaluating the efficacy and safety of bremelanotide for the treatment of FSD. The amounts of project spending above exclude general research and development spending, which decreased to $2.9 million for fiscal 2013 compared to $3.9 million for fiscal 2012. The decrease was the result of closing our research laboratory operations in connection with the lease expiration of our laboratory facilities in July 2012.

General and Administrative — General and administrative expenses were $5.1 million for fiscal 2013 compared to $5.0 million for fiscal 2012. These expenses mainly consisted of compensation and related costs.

Other Income (Expense) — Other income (expense) was $(7.0) million and $0.5 million for fiscal 2013 and fiscal 2012, respectively. Fiscal 2013 other expense included the recognition of $7.1 million non-cash charged for the increase in the fair value of warrants related to the July 3, 2012 private placement offering from $0.50 per share at date of issuance to $0.71 per share upon shareholder approval.

There were no warrants required to be liability classified or any changes in fair value of warrants during fiscal 2012. Fiscal 2012 other income included a gain on disposition of supplies and equipment of $0.4 million compared to $5,000 for fiscal 2013. This increase was a result of closing our research laboratory facilities in July 2012. For fiscal 2013 we recognized $43,000 of investment income compared to $32,000 of investment income for fiscal 2012.

Income Tax Benefit — Income tax benefits of $1.8 million in fiscal 2013 and $1.1 million in fiscal 2012 related to the sale of New Jersey state net operating loss carryforwards.

Liquidity and Capital Resources

Since inception, we have incurred net operating losses, primarily related to spending on our research and development programs. We have financed our net operating losses primarily through equity financings and amounts received under collaborative agreements.

Our product candidates are at various stages of development and will require significant further research, development and testing and some may never be successfully developed or commercialized. We may experience uncertainties, delays, difficulties and expenses commonly experienced by early stage biopharmaceutical companies, which may include unanticipated problems and additional costs relating to:

the development and testing of products in animals and humans;
product approval or clearance;
·the development and testing of products in animals and humans;
regulatory compliance;
GMPs;
·product approval or clearance;
intellectual property rights;
product introduction;
·regulatory compliance;
marketing, sales and competition; and
obtaining sufficient capital.
·good manufacturing practices;
·intellectual property rights;
·product introduction;

·marketing, sales and competition; and
·obtaining sufficient capital.

Failure to enter into or successfully perform under collaboration agreements and obtain timely regulatory approval for our product candidates and indications would impact our ability to increase revenues and could make it more difficult to attract investment capital for funding our operations. Any of these possibilities could materially and adversely affect our operations and require us to curtail or cease certain programs.

TABLE OF CONTENTS

We have incurred cumulative negative cash flows from operations since our inception, and have expended, and expect to continue to expend in the future, substantial funds to complete our planned product development efforts. As of June 30, 2010,2014, our cash and cash equivalents were $5.4$12.2 million and our available-for-sale investmentscurrent liabilities were $3.5$1.8 million, net of unearned revenue of $1.0 million.

This raises substantial doubt about our ability to continue as a going concern. We have made the strategic decision to focus resources and efforts onPhase 3 clinical trials for our primary product candidate, bremelanotide for FSD, and PL-3994secondarily for clinical and preclinical development of an inhaled formulation ofour other product candidates and programs, including PL-3994 and a new peptide drug candidateMC1r and MC4r programs. The remainder of our capital resources will be allocated for sexual dysfunction,general corporate purposes and have ceased research and development efforts on newworking capital. We believe that the Phase 3 clinical trial program for bremelanotide, including regulatory filings for product candidates. As partapproval, will cost at least $80.0 million. We are preparing to start patient enrollment in the bremelanotide Phase 3 program in the fourth quarter of this decision,calendar 2014, but may curtail or delay clinical trial initiation unless we have implemented reductions in staffing levels, and anticipate having no more than twenty employees by December 31, 2010.

However, sufficient

We believe that our existing capital resources, together with approximately $8.8 million received on execution of our agreement with Gedeon Richter, will be adequate to fund our planned operations through the quarter ending September 30, 2015, not including initiation of our pivotal Phase 3 clinical trials for bremelanotide for FSD or other planned clinical trials. Following this offering, assuming the Phase 3 clinical trials of bremelanotide for FSD are successful, as to which there can be no assurance, we will need additional funding to support projected operations, includingcomplete submission of required regulatory applications to the FDA for bremelanotide for FSD. We will also need additional funding to complete required clinical trials with either bremelanotide or PL-3994, or both, may not be available on acceptable terms or at all. We may be required to seek collaborators for our other product candidates at an earlier stage than otherwise wouldand, assuming those clinical trials are successful, as to which there can be desirable and on terms that are less favorable than might otherwise be available, and relinquish, license or otherwise disposeno assurance, to complete submission of rights on unfavorable termsrequired regulatory applications to technologies and product candidates that we would otherwise seek to develop or commercialize ourselves. The nature and timing of our development activities are highly dependent on our financing activities.

If we are unable to raise sufficient additional funds to advance at least one of our product candidates, we will implement plans for the orderly wind down of our business operations, including curtailing operations significantly and further decreasing staffing levels, and will seek to license, sell or otherwise dispose of our product candidates, technologies and contractual rights, including rights under our research collaboration and license

We anticipate incurring additional losses over at least the next few years. To achieve profitability, if ever, we, alone or with others, must successfully develop and commercialize our technologies and proposed products, conduct preclinical studies and clinical trials, obtain required regulatory approvals and successfully manufacture and market such technologies and proposed products. The time required to reach profitability is highly uncertain, and we do not know whether we will be able to achieve profitability on a sustained basis, if at all.

Overview

We are a biopharmaceutical company dedicated todeveloping targeted, receptor-specific peptide therapeutics for the developmenttreatment of peptide, peptide mimeticdiseases with significant unmet medical need and small molecule agonist compounds with a focuscommercial potential. Our programs are based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. WeOur primary product in clinical development is bremelanotide for the treatment of FSD. In addition, we have a pipeline ofdrug candidates or development programs targetingfor obesity, erectile dysfunction, cardiovascular diseases, pulmonary diseases, inflammatory diseases and dermatologic diseases.

The following drug development programs are actively under development:

Bremelanotide, an on-demand subcutaneous injectable peptide melanocortin and natriuretic receptors, including development of proposed productsreceptor agonist, for treatment of FSD in premenopausal women. Bremelanotide, which is a melanocortin agonist, is a synthetic peptide analog of the naturally occurring hormone alpha-MSH. The novel mechanism of action involves activating endogenous melanocortin hormone pathways involved in sexual dysfunction, acute asthma, heart failure, hypertension, obesity, diabetes and metabolic syndrome.response. Bremelanotide is scheduled to start Phase 3 clinical trials in the last quarter of calendar 2014;
Our Product Candidates
We currently have the following active drug development programs:
·Bremelanotide, a peptide melanocortin receptor agonist, for treatment of sexual dysfunction, targeting female sexual dysfunction (FSD) and erectile dysfunction (ED) in patients non-responsive to current therapies.
·Peptide melanocortin receptor agonists for treatment of FSD and ED.
·PL-3994, a peptide mimetic natriuretic peptide receptor A (NPR-A) agonist, for treatment of acute exacerbations of asthma, heart failure and refractory or difficult-to-control hypertension.
We have licensed several families of melanocortin receptor-basedMC4r compounds for treatment of obesity and diabetes and related metabolic syndrome toin collaboration with AstraZeneca AB (AstraZeneca) pursuant to our research collaboration and license agreementagreement. Results of our studies involving MC4r peptides suggest that certain of these peptides may have significant commercial potential for treatment of conditions responsive to MC4r activation, including FSD, ED, obesity and diabetes;
PL-3994, an NPR-A agonist, for treatment of cardiovascular and pulmonary indications. PL-3994 is our lead natriuretic peptide receptor product candidate, and is a synthetic mimetic of the neuropeptide hormone ANP. PL-3994 is in development for treatment of heart failure, acute exacerbations of asthma and refractory hypertension; and
MC1r agonist peptides for treatment of inflammatory and dermatologic disease indications. Our MC1r peptide drug candidates are highly specific, with AstraZeneca.substantially greater binding and efficacy at MC1r than at other melanocortin receptors. We have selected one of our MC1r peptide drug candidates, designated PL-8177, as a clinical trial candidate.

Strategy

Key elements of our business strategy include:

Using our technology and expertise to develop and commercialize products in our active drug development programs;
Entering into strategic alliances and partnerships with pharmaceutical companies to facilitate the development, manufacture, marketing, sale and distribution of product candidates that we are developing;
Partially funding our product development programs with the cash flow generated from research collaboration and license agreements and any potential future agreements with third parties; and
Completing development and seeking regulatory approval of bremelanotide for FSD and our other product candidates.

Our Melanocortin Receptor-Specific Programs

The melanocortin system is involved in a large and diverse number of physiologic functions, and therapeutic agents modulating this system may have the potential to treat a variety of conditions and diseases, including sexual dysfunction, obesity and related disorders, cachexia (wasting syndrome)pigmentation disorders and inflammation-related diseases.

Bremelanotide for Sexual Dysfunction. FSD.We are developing subcutaneously administered bremelanotide for the treatment of FSD and ED in patients non-responsive to current therapies.premenopausal women. Bremelanotide, which is a melanocortin agonist, (a compound which binds to a cell receptor and triggers a response) drug candidate, is a synthetic peptide analog of the naturally occurring hormone alpha-MSH (melanocyte-stimulating hormone).alpha-MSH. The novel mechanism of action involves activating endogenous melanocortin hormone pathways involved in sexual arousal response. We have completed a Phase 2B clinical trial and meetings with the FDA, and are preparing to start patient enrollment in the Phase 3 clinical trials in the fourth quarter of calendar 2014, but may curtail or delay clinical trial initiation unless we have adequate funds, or commitments for adequate funds, to complete the Phase 3 clinical trials.

In August 2014, we entered into an agreement with Gedeon Richter to co-develop and commercialize bremelanotide for FSD in the European Union, other European countries and additional selected countries. Under this agreement we will contribute, with Gedeon Richter, to the costs of co-development activities for obtaining regulatory approval in Europe. Gedeon Richter will exclusively market bremelanotide for FSD in the licensed territory, and will be responsible for all sales, marketing and commercial activities, including associated costs, in the licensed territory. Gedeon Richter is a European pharmaceutical company with a focus on female healthcare, with $1.6 billion in sales in 2013, of which $500 million was in female healthcare.


 

TABLE OF CONTENTS

We have received €7.5 million ($9.8 million) in total upfront payments from Gedeon Richter, and will receive a milestone payment of €2.5 million ($3.3 million) upon the initiation of our Phase 3 clinical trial program in the United States. We have the potential to receive up to €80 million ($105.6 million) in regulatory and sales related milestones, consisting of $26.4 million in regulatory milestones and $79.2 in sales milestones, and low double-digit royalties on net sales in the licensed territory. Our agreement remains in effect as long as Gedeon Richter is selling bremelanotide on which a royalty is owed. The agreement may be terminated by either party upon notice in the event of a material breach or insolvency. In the event Gedeon Richter terminates the agreement because we breached the agreement or are insolvent, Gedeon Richter’s license will become fully paid-up, royalty free, perpetual and irrevocable. If Palatin fails to initiate its Phase 3 program on or before December 31, 2014, Gedeon Richter at its option may elect to terminate the license and receive a payment equal to one-half of the total upfront payments of €7.5 million ($9.8 million). In the event that we terminate the agreement because Gedeon Richter breached the agreement or is insolvent, upon timely request all regulatory approvals for bremelanotide in the licensed territory will be transferred to us or our designee.

We are in active discussions with potential partners for U.S. marketing and commercialization rights for bremelanotide. We may not be able to enter into suitable agreements with potential partners on acceptable terms, if at all.

Phase 2B Clinical Trial Results.  The Phase 2B clinical trial was a multicenter, placebo-controlled, randomized, parallel group, dose-finding trial testing three dose levels, 0.75 mg, 1.25 mg and 1.75 mg, of subcutaneously administered bremelanotide against placebo in premenopausal women diagnosed with hypoactive sexual desire disorder, female sexual arousal disorder or both. The study enrolled 395 premenopausal women across 66 sites within the United States and Canada, with patients randomized to one of three bremelanotide treatment arms and a placebo arm for 16 weeks of treatment. The objective of the Phase 2B trial was to measure safety and efficacy in premenopausal women with hypoactive sexual desire disorder, female sexual arousal disorder or both of bremelanotide compared to placebo. In the Phase 2B trial, subcutaneous doses of bremelanotide and placebo were self-administered by the patient prior to a sexual encounter. The primary efficacy endpoint was change from baseline to end of study in the number of satisfying sexual events, with pre-specified analysis of pooled 1.25 and 1.75 mg doses compared to placebo.

In the Phase 2B clinical trial, the primary endpoint data analysis of 327 pre-menopausal women with hypoactive sexual desire disorder, female sexual arousal disorder or both showed statistically significant and clinically meaningful increases in the number of satisfying sexual events, and statistically significant and clinically meaningful improvement in secondary endpoint measures of overall sexual functioning and distress related to sexual dysfunction, for women taking bremelanotide compared to placebo. Satisfying sexual events were measured with an event log and overall sexual functioning and distress related to sexual dysfunction were measured using validated patient reported outcome measurement tools. Bremelanotide showed a statistically significant increase from baseline in the number of satisfying sexual events compared against placebo at both the 1.75 mg dose and pooled results of the 1.75 and 1.25 mg doses. The mean increase in satisfying sexual events at 1.75 mg dose levels was 0.8 satisfying sexual events per month, from 1.8 to 2.6, with a p value of 0.021 against placebo. For the pooled doses, the mean increase in satisfying sexual events was 0.7 satisfying sexual events per month, from 1.6 to 2.4 (a 50% increase), with a p value of 0.018 against placebo. By contrast, with placebo, the mean change from baseline was from 1.7 to 1.9 (a 12% increase) in satisfying sexual events. The 0.75 mg dose demonstrated a response that was not significant different from placebo.

The mean change from baseline in a validated measurement tool of overall sexual functioning, the Female Sexual Function Index, or FSFI, total score, was 4.4 at the 1.75 mg dose level, compared to 1.88 for placebo, with a p value of 0.0021 against placebo. For the pooled doses, the FSFI total score mean change from baseline was 3.55, compared to 1.88 for placebo, with a p value of 0.0017 against placebo. The FSFI is a 19-item questionnaire measuring improvement in arousal, desire and overall sexual function.

The mean change from baseline in a validated measurement tool of distress related to sexual dysfunction, the Female Sexual Distress Scale-Desire/Arousal/Orgasm, or FSDS-DAO, total score, was -13.1 at the 1.75 mg dose level, compared to -6.8 for placebo, with a p value of 0.0005 against placebo. For the pooled doses, the

FSDS-DAO total score mean change from baseline was -11.1, compared to -6.8 for placebo, with a p value of 0.036 against placebo. The FSDS-DAO is a 15-item questionnaire that measures personal distress associated with FSD.

[GRAPHIC MISSING]

A significantly higher percentage of women receiving the 1.75 mg bremelanotide dose, 55%, achieved a clinically meaningful change from baseline of at least one satisfying sexual event compared to 37% of women receiving placebo. In addition, compared against placebo a significantly higher percentage of women also achieved a clinically meaningful improvement in sexual function, as measured by the FSFI (53% vs. 29%), and a clinically meaningful decrease in distress associated with sexual dysfunction as measured by the FSDS-DAO (69% vs. 45%).

Using a validated self-assessment questionnaire of treatment benefit, 79.5% of blinded patients receiving the 1.75 mg dose of bremelanotide reported they benefited from taking the drug, compared to 48.4% of blinded patients receiving placebo.

Bremelanotide was well-tolerated during the Phase 2B clinical trial. The most common types of treatment-emergent adverse events reported more frequently in the bremelanotide arms were facial flushing, nausea, emesis and headache, which were mainly mild-to-moderate in severity. Adverse events that most commonly led to discontinuation were nausea and emesis, with less than 3% discontinuation due to an adverse event. Twenty-six patients, evenly distributed among placebo and active arms of the Phase 2B clinical trial, met the predefined blood pressure withdrawal criteria. Drug treated patients had approximately a 2 mm Hg change in blood pressure, predominately during the first four hours following dosing. No serious adverse events were attributable to bremelanotide during the trial.

Full data on the Phase 2B clinical trial was presented at the March 2013 annual meeting of the International Society for the Study of Women’s Sexual Health.

Phase 3 Clinical Trial Plans.  We have reached preliminary agreement with the FDA on key aspects of the bremelanotide Phase 3 pivotal registration studies, including FSD patient population, primary and key secondary efficacy endpoints, general study design, dose selection and safety monitoring. In addition, the FDA agreed that the Phase 2 data adequately characterized blood pressure and heart rate signals of bremelanotide, and that standardized methods for in-clinic assessment of blood pressure (a standard blood pressure cuff) would be sufficient for Phase 3. It was also agreed that the intranasal Definitive QTc study was acceptable for NDA submission, as were the carcinogenicity and reproductive toxicity studies. There were no outstanding chemistry, controls or manufacturing issues. Based upon the discussions with the FDA, we have completed


TABLE OF CONTENTS

and submitted protocols for the pivotal Phase 3 studies in the early fourth quarter of calendar 2014, have manufactured drug product for clinical trial use and are in the process of negotiating agreements with clinical research organizations and others for Phase 3 studies.

The Phase 3 clinical trials will be conducted in premenopausal women with hypoactive sexual desire disorder, either with or without arousal difficulties, and will include two pivotal double blind placebo-controlled, randomized parallel group trials each with 550 randomized patients in two arms, one a fixed bremelanotide dose and one placebo. Hypoactive sexual desire disorder is the single largest specific diagnosis in FSD. A 24-week treatment evaluation period will be utilized, with co-primary endpoints of satisfying sexual events and the FSFI desire subdomain (a 28 day recall), and a key secondary endpoint utilizing question 13 of a revised FSDS questionnaire. Patients in the parallel group trials will have the option, after completion of the trial, to continue in an open-label safety extension study, which will enroll about 600 patients.

Data from the Phase 2B clinical trials from patients diagnosed with the proposed Phase 3 patient population, hypoactive sexual desire disorder or hypoactive sexual desire disorder with female sexual arousal disorder, were analyzed using the Phase 3 clinical trial endpoints of total satisfying sexual events, the FSFI desire subdomain and FSDS revised question 13. This analysis showed that the 1.75 mg dose was statistically and clinically significant for all three endpoints.

[GRAPHIC MISSING]

The Phase 3 trials, which will be conducted in North America, will utilize a single-dose autoinjector intended for commercialization. We will also conduct drug interaction and other ancillary studies. It is anticipated that the Phase 3 program will take at least eighteen months from initiation of patient dosing through database lock. Following database lock, clinical trial data will be analyzed and, assuming that we believe the data would support approval of bremelanotide for FSD, an NDA will be submitted to FDA. There can be no assurance that the Phase 3 data will support approval of bremelanotide for FSD or that the FDA will approve an NDA for bremelanotide.

With Gedeon Richter, we met with the European Medicines Agency and received regulatory advice on the Phase 3 clinical data required for approval of bremelanotide for FSD in the European Union. We anticipate that clinical studies will be conducted in Europe, including a pivotal trial with approximately 900 randomized patients which is planned to start in the second half of calendar year 2015.

Medical Need - FSD.  FSD is a multifactorial condition that has anatomical, physiological, medical, psychological and social components.components, and is defined as persistent or recurring problems during one or more of the stages of sexual response with associated distress. FSD has a significant impact on a patient’s self-image, relationships and general well-being. FSD includes four disorders, hypoactive sexual desire disorder, female sexual arousal disorder, sexual pain disorder and orgasmic disorder. Hypoactive sexual desire disorder, either with or without arousal difficulties, is the largest single category of FSD. To establish a diagnosis of FSD, these syndromes must be associated with personal distress, as determined by the affected women. Approximately 40 million American women are affected by FSD. The National Health and Social Life Survey,2006 PRESIDE study, a probability sample studycross-sectional, population-based survey of sexual behavior31,581 female adult respondents in a demographically representative cohort ofthe United States adults ages 18 to 59,published in 2008 in the journalObstetrics & Gynecology, found that approximately 43%22% of women suffer from some formreported a sexual problem and 11% were distressed by their sexual problems, with one-third of FSD.

the women seeking formal care. There are 60 million premenopausal women in the United States according to the 2010 U.S. Census, giving a presenting market size of premenopausal women of about two million. Based on a report by EvaluatePharma, the FSD market is projected to be about $1.3 billion by 2020.

There are no drugs approved for FSD indications in the United States approved for FSD indications.

Medical Need - ED. ED is the consistent inability to attain and maintain an erection sufficient for sexual intercourse. The condition is correlated with increasing age, cardiovascular disease, hypertension, diabetes,

25


hyperlipidemia and smoking. In addition, certain prescription drugs and psychogenic issues may contribute to ED. According to the Massachusetts Male Aging Study, more than 50% of men aged 40-70 report episodes of ED and more than 30 million men in the United States may be afflicted with some form of ED, with less than 20% seeking treatment. The incidence of ED increases with age. Studies show that chronic ED affects about 5% of men in their 40s and 15% to 25% of men by the age of 65. The current market size for ED is more than $4 billion per year.
PDE-5 inhibitors such as sildenafil (Viagra®), vardenafil (Levitra®) and tadalafil (Cialis®) are used to treat ED, but an estimated 35% of ED patients are non-responsive to PDE-5 inhibitor therapy. There are limited therapeutic options for ED patients non-responsive or inadequately responsive to PDE-5 inhibitor therapy, including alprostadil for direct penis injection or urethral suppositories, surgical penile implants and various devices.
Mechanisms of Action withStates.

Subcutaneous Bremelanotide.  Bremelanotide, which is believed to act through activation of melanocortin receptors in the central nervous system, is a first-in-class pharmaceutical agent in development as a treatment of FSD.

Bremelanotide is intended for “on-demand” use and is self-administered by the patient approximately one hour prior to anticipated sexual activity. We have selected a simple and patient-friendly single dose, disposable autoinjector device which is a different mechanism of action from currently marketed PDE-5 inhibitor ED therapies that act directly on the vascular system. Studies have demonstrated efficacy with bremelanotideexpected to be used in ED patients non-responsive to PDE-5 inhibitor therapies. Studies have also demonstrated an additive effect in ED patients co-administered both bremelanotide and a PDE-5 inhibitor.

Clinical Trials with Intranasal Formulations. We extensively studied bremelanotide for sexual dysfunction in nasal formulations, administered as a single spray in one nostril. Increases in blood pressure were observed in some patients receiving nasally administered bremelanotide, and this observed increase was a significant factor leading us to discontinue work on nasally administered bremelanotide as a first-line therapy for sexual dysfunction. We believe that the amount of increase in blood pressure, as well as the rate of nausea and emesis (vomiting), was due, at least partially, to high doses resulting from variability in drug uptake with nasal administration. Studies showed significant variation in plasma levels of bremelanotide in patients receiving nasally administered bremelanotide.
While we are no longer developing intranasal formulations of bremelanotide for commercialization, trials with intranasal formulations of bremelanotide did demonstrate potential utility of bremelanotide. Phase 2B double blind, placebo-controlled, parallel doses3 clinical trials evaluating nasal bremelanotideand is intended for ED, conducted in 726 non-diabetic and 294 diabetic patients, showed that over 30% of ED patients were restored to a normal level of function. Phase 2A clinical trials of post-menopausal FSD patients showed a statistically significant increase in the level of sexual desire and genital arousal in subjects receiving nasal bremelanotide compared to subjects receiving placebo and, in pre-menopausal FSD patents, a trend to increases in the level of sexual desire and genital arousal in subje cts receiving nasal bremelanotide compared to subjects receiving placebo. In trials conducted to date, almost 2,000 patients received at least one dose of bremelanotide, with about 1,500 receiving multiple doses.
Subcutaneous Administration of Bremelanotide. In acommercialization.

Prior Clinical Trials.  We have completed several Phase 1 clinical trial designed to evaluate thestudies in which various safety parameters, including blood pressure effects of subcutaneously administered bremelanotide, no statistically significant differencewere studied. Based in mean changes inpart on these studies, our Phase 2B clinical trial assessed the magnitude and duration of blood pressure was seen in subjects receiving bremelanotide compared to placebo. No subject discontinued participation in the trial as a resulteffect, and determined that subcutaneous administration of protocol stopping rules based on blood pressure changes. In addition, there was no difference in the incidence of emesis in subjects receiving bremelanotide compared to placebo. This Phase 1 trial was a two-week, randomized, double-blind, placebo-controlled study in subjects who received 45 repeatselected doses of bremelanotide or placebo subcutaneously. Each administered dos efor treatment of bremelanotide achieved plasma levelsFSD in premenopausal women provides acceptable control of blood pressure effects. We have also completed clinical studies involving an alternative route of administration. Bremelanotide has been evaluated in 31 clinical studies involving about 2,300 subjects, and has shown to be efficaciousefficacy in both FSD and ED.

MC1r Peptide Agonists.  We have initiated preclinical studies with MC1r peptide drug candidates for improving erectile functiona number of indications, primarily inflammatory disease-related and autoimmune indications. The MC1r is upregulated in multiple previous Phase 1a number of diseases, including inflammatory bowel disease, nephritis, which is inflammation of the kidneys, and Phase 2 erectile dysfunction studies.

system and resolution of pro-inflammatory responses. MC1r peptides also have potential application in a number of dermatologic indications, including vitiligo and erythropoietic protoporphyria.

Our MC1r peptide drug candidates are highly specific, with substantially greater binding and efficacy at MC1r than at other melanocortin receptors. In vitro safety studies have shown that our MC1r peptide drug candidates have no activity in a wide range of various receptors, ion channels and kinases. Our MC1r peptide drug candidates typically have a half-life in animal models of greater than two hours. We have selected one of our MC1r peptide drug candidates, designated PL-8177, as a clinical trial candidate.

Animal studies that we have conducted with our MC1r peptide drug candidates have shown positive results in experimental models of inflammatory bowel disease, uveitis and nephritis. We are continuing to conduct studies on a number of different indications. We have completed a placebo-controlled, randomized, double-blind, cross over safety study evaluating blood pressure effects of subcutaneous bremelanotide in healthy male volunteers between 45preclinical toxicology testing on PL-8177 and 65 years old. The study also evaluated dose-to-dose consistency of plasma exposure of bremelanotide. A total of 49 subjects were dosed in the safety study; 19 of the subjects were enrolled in a sub-studychemistry, controls and completed a graded exercise treadmill test as a surrogate for the cardiovascular effects of sexual activity. The results demonstrate that with subcutaneous administration consistent therapeutic blood plasma levels can be obtained without sustained clinically significant blood pressure effects.

Next Clinical Trial Steps. We are submitting protocols and a meeting requestmanufacturing activities to the FDA for initiation of an at-homesupport Phase 2 clinical trial of subcutaneously administered bremelanotide for women with FSD,1 studies, and anticipate thatfiling an IND application on PL-8177 as early as the meeting will be held late early in the firstfourth quarter of calendar 2011. Assuming concurrence of the FDA, and depending2014. Contingent on financial resources, thisadequate available funds, we anticipate conducting a first-in-man Phase 2 at home1 clinical trial for women with FSD could start as early asin the first half of calendar 2011. In the fourth quarter of calendar 2010 we intend to submit protocols to the FDA for initiation of an in-clinic Phase 2 clinical trial of subcutaneously administered bremelanotide, as either monotherapy

or a combination therapy with a PDE-5 inhibitor such as sildenafil, for men with ED who are non-responsive or inadequately responsive to PDE-5 inhibitor therapies alone. Assuming concurrence of the FDA, and depending on financial resources, this Phase 2 clinical trial for men with ED could start as early as the first quarter of calendar 2011.
Delivery of Bremelanotide. Injection sites for subcutaneous injection of bremelanotide include the abdomen, thigh and upper arms.2015.

MC4r Peptide Agonists.  We are exploring various delivery devices for subcutaneous administration. We believe that fine needle devices, pen injectors and needle-free injector systems can be used for subcutaneous administration of bremelanotide, and are evaluating various delivery devices for potential commercialization. If Phase 2 clinical trials for ED or FSD are successful, we anticipate that Phase 3 clinical trials will be conducted with a delivery device intended for commercialization.

Peptide and Small Molecule Melanocortin Receptor Agonists for Treatment of Sexual Dysfunction. Wehave developed a series of lead alternative melanocortin receptor-specific peptides for treatment of sexual dysfunction, and have demonstrated efficacy with certain of these peptides in inducing erections in animal models.
next generation highly selective MC4r peptides. In developing these peptides, we used a novel screening platform that examined the effectiveness of peptides in animal models of sexual response and effectiveness in obesity and related metabolic signals, and also determined cardiovascular effects, primarily looking at changes in blood pressure. InResults of these animal models,studies suggest that certain of these peptides resulted in significantly smaller increases in blood pressure at doses effective for a sexual response than increases in blood pressure in the same models seen with comparably effective doses of bremelanotide. Additionally, many of these peptides are highly selective for the specific melanocortin receptor believed to be involved in sexual response, and thus may have an improved side effect and safety profile.
We have suspended further discovery work on our alternative melanocortin receptor-specific peptides, but intend, depending on financial resources, to advance one or more of the peptides we have developed to preclinical toxicology and other studies required by the FDA prior to initiating human clinical trials.
We have suspended our development program for small molecule melanocortin receptor-specific compoundssignificant commercial potential for treatment of sexual dysfunction.

We have selected an internal lead compound for obesity, designated PL-8905, which has over 100-fold functional selectivity for MC4r over MC1r with minimal effect on blood pressure and limited central nervous system penetration. PL-8905 exhibits chemical and metabolic stability, with a half-life in animal models of greater than two hours. The following graphic illustrates results in a rat model of obesity.

Obesity Collaboration with AstraZeneca.In 2007, we entered into an exclusive global research collaboration and license agreement with AstraZeneca to discover, develop and commercialize compounds that target melanocortin receptors for the treatment of obesity, diabetes and related metabolic syndrome. The goal was to design and develop selective MC4r agonists with limited off-target effect, and without toxicities associated with small molecules. In June and December 2008 and in September 2009, the research collaboration and license agreement was amended to include additional compounds and associated intellectual property that we developed and to modify royalty rates and milestone payments. Active work under the collaboration portion of the agreement concluded in January 2010,2010.

AstraZeneca initiated human clinical studies with AZD2820, a subcutaneously-administered peptide melanocortin receptor partial agonist that was being developed as a single-agent therapy for the treatment of obesity, but we are still providing certaindiscontinued development after a Phase 1 clinical trial of AZD2820 was halted following a serious adverse event. Based on an investigation, it could not be excluded that the serious adverse event was linked to AZD2820, but it was determined that it was unlikely that the serious adverse event was related to melanocortin agonists as a target for treatment of obesity, and other servicesthus was a compound-specific safety concern. AstraZeneca is evaluating its program and next steps. No assurance can be given that AstraZeneca will continue to AstraZeneca.develop compounds that target melanocortin receptors for the treatment of obesity, diabetes and related metabolic syndrome, or that AstraZeneca will be successful in developing any such compound.


 

TABLE OF CONTENTS

Obesity is a multifactorial condition with significantnumerous biochemical components relating to satiety (feeling full), energy utilization and homeostasis. A number of different metabolic and hormonal pathways are being evaluated by companies around the world in efforts to develop better treatments for obesity. Scientific research has established that melanocortin receptors have a role in eating behavior and energy homeostasis, and that some melanocortin receptor agonists can decrease food intake and induce weight loss.

Obesity is a

With AstraZeneca we completed clinical proof-of-concept studies for the MC4r mechanism in obesity, which met the primary objectives of significant healthcare issue, often correlated with a variety of cardiovascular and other diseases, including diabetes. More than 1.1 billion adults and over 150 million children worldwide are overweight, with over 300 million adults categorized as obese. According to the American Obesity Association, obesity is the second leading cause of preventable death after smoking and nearly one-third of adultsdecrease in the United States are obese. Increased mortality, high blood pressure, diabetes and other substantial health risks are associated with being overweight and obese. Over 2.6 million deaths are attributed to diabetes each year worldwide and almost $120 billion is spent on related costs of obesity, according to the U.S. Surgeon General.

We developed classes of small molecule and peptide compounds targeting melanocortin receptors which are effective in the treatment of obesity in animal models. Certain of these compounds have been demonstrated to be effective in normal diet-induced obese and genetically obese animal models for decreasing food intake and body weight without an increase in sexual response in normal animals at the same or higher dose levels. Pursuant to clinical trial agreements with AstraZeneca, we have conducted proof-of-principle clinical trials on the effects of a melanocortin receptor-specific compound on food intake, obesity and other metabolic parameters, and have agreed to conduct additional related studies at a negotiated rate.
Pursuant to the terms of the research collaboration and licenseloss.

Our agreement with AstraZeneca remains in effect as long as AstraZeneca is developing a compound covered by the agreement or commercializing a product for which a royalty is owed. The agreement may be terminated by AstraZeneca at any time upon notice to us, or by either party upon notice in the event of a material breach. Upon termination by AstraZeneca without cause or by us for cause, all rights and licenses that we granted to AstraZeneca terminate, but AstraZeneca remains obligated to pay royalties and milestones on compounds developed during the collaboration portion of the agreement. In the event AstraZeneca terminates the agreement because we breached the agreement, rights and licenses that we granted under the agreement become permanent, with financial terms, including royalties, to be determined by arbitration.

AstraZeneca has responsibility for product commercialization, product discovery and development costs.

Other Melanocortin Programs.  We have suspended work on our other early stage research andare continuing drug discovery programs exploring additional indications and targets. These programs include development ofefforts in the melanocortin field, primarily developing peptide compounds, including highly selective melanocortin-1MC1r agonists and melanocortin-3 receptorpeptides specific for MC4r, including both agonists for treatment of inflammation-related diseases and disorders and melanocortin-4 receptor antagonists for treatment of cachexia. We do not anticipate that any significant effort will be devoted to these programs during the next twelve months.

Our Natriuretic Peptide Receptor-Specific Programs

The natriuretic peptide receptor system has numerous cardiovascular functions, and therapeutic agents modulating this system may be useful in treatment of heart failure, hypertension, acute asthma, other pulmonary diseases and other cardiovascular diseases.

hypertension. While the therapeutic potential of modulating this system is well appreciated, development of therapeutic agents has been difficult due, in part, to the short biological half-life of native peptide agonists.

We have designed and are developing candidate drugs that are selective for different natriuretic peptide receptors, including NPR-A, natriuretic peptide receptor B, or NPR-B, natriuretic peptide receptor C, or NPR-C, and both NPR-A and NPR-B.

We are in active discussions with potential partners for marketing and commercialization rights in the United States and the rest of the world for PL-3994 and our related candidate drugs. We may not be able to enter into suitable agreements on acceptable terms with potential partners, if at all.

PL-3994.PL-3994 is our lead natriuretic peptide receptor product candidate, and is a synthetic mimetic of the neuropeptide hormone ANP and an NPR-A agonist compoundagonist. PL-3994 is in development for treatment of heart failure, acute exacerbations of asthma heart failure and refractory hypertension. PL-3994 activates NPR-A, a receptor known to play a role in cardiovascular homeostasis. Consistent with being an NPR-A agonist, PL-3994 increases plasma cyclic guanosine monophosphate, (cGMP)or cGMP, levels, a pharmacological response consistent with the effects of endogenous (naturally produced) natriuretic peptides on cardiovascular function and smooth muscle relaxation. PL-3994 also decreases activity of the renin-angiotensin-aldosterone system, (RAAS),or RAAS, a hormone system that regulates blood pressure and fluid balance. The RAAS system is frequently over-activated in heart failure patients, leading to worsening of cardiovascular funct ion.function. The following graphic illustrates the action of the natriuretic peptide system.

Acute exacerbations of asthma, also called acute severe asthma, is an ongoing asthma episode in which asthma symptoms do not adequately respond to initial bronchodilator or corticosteroid therapy. Inhaled beta-2 adrenergic receptor agonists, such as albuterol, and inhaled corticosteroids are primary treatments for asthma episodes. Some patients with acute exacerbations of asthma become unresponsive to beta-2 adrenergic receptor agonists, significantly limiting treatment options and increasing risk.
In 2006, the most recent year reported, there were almost 1.7 million emergency room visits due to asthma, with 440,000 hospitalizations attributed to asthma. In 2008, approximately 23.3 million Americans had asthma, with a projected 2010 economic cost in the United States of $20.7 billion, of which the largest single direct medical expenditure, $5.9 billion, is for prescription drugs.
Existing therapies for acute exacerbations of asthma in patients unresponsive to beta-2 adrenergic receptor agonists have limitations, including typically taking several hours for significant patient improvement. Existing therapies include oxygen, systemic steroids and anticholinergic drugs. PL-3994, which works through a different pathway than beta-2 adrenergic receptor agonists and other approved bronchodilators, is intended to address this unmet medical need.
Research over the past two decades has demonstrated potent bronchodilator effects with both systemic and inhalation administration of natriuretic peptides. NPR-A agonism is known to relax smooth muscles in airways and works through a pathway independent of the beta-2 adrenergic receptor. Preclinical testing demonstrated potent airway smooth muscle relaxation in rat, guinea pig and human tissues using PL-3994, and animal studies in sensitized guinea pigs has demonstrated a bronchodilator effect with PL-3994 using both subcutaneous and inhalation administration.
Endogenous natriuretic peptides have a very short half-life, due primarily to degradation by neutral endopeptidase and clearance through the natriuretic peptide clearance receptor. PL-3994 is resistantamenable to neutral endopeptidase and clears from the body much more slowly than endogenous natriuretic peptides. PL-3994 has a blood-plasma half-life of at least three hours in humans when administered byonce daily chronic use subcutaneous injection, with biological effects seen for over eight hours post-administration.
We have planned a proof-of-concept human trial for asthma using a subcutaneously administered formulation of PL-3994, and will submit an IND application to the FDA in the fourth quarter of calendar 2010 for this trial. We also have an inhalation formulation of PL-3994 under development. Depending on financial resources,

administration.

PL-3994 for Heart Failure.  Heart failure is an illness in which the heart is unable to pump blood efficiently, and includes acutely decompensated heart failure with dyspnea (shortness of breath) at rest or with minimal activity. Endogenous natriuretic peptides have a number of beneficial effects, including vasodilation (relaxation of blood vessels), natriuresis (excretion of sodium), and diuresis (excretion of fluids).

Patients who have been admitted to the hospital with an episode of worsening heart failure have an increased risk of either death or hospital readmission in the three months following discharge. Up to 15% of patients die in this period and as many as 30% need to be readmitted to the hospital. We believe that decreasing mortality and hospital readmission in patients discharged following hospitalization for worsening heart failure is a large unmet medical need for which PL-3994 may be effective. PL-3994 wouldcould potentially be utilized as an adjunct to existing heart failure medications, and may, if successfully developed, be self-administered by patients as a subcutaneous injection following hospital discharge. We believe that PL-3994, through activation of NPR-A, may, if successful, reduce cardiac hypertr ophyhypertrophy (increase in heart size due to disease), which is an independent risk factor for cardiovascular morbidity and mortality.

Over 5.7 million Americans suffer from heart failure, with 670,000 new cases of heart failure diagnosed each year, with disease incidence expected to increase with the aging of the American population. Despite the treatment of heart failure with multiple drugs, almost all heart failure patients will experience at least one episode of acute heart failure that requires treatment with intravenous medications in the hospital. Heart failure has tremendous human and financial costs. EstimatedFor 2010, the estimated direct costs in the United States for heart failure are $37.2were $39.2 billion, in 2009, with heart failure constituting the leading cause of hospitalization in people over 65 years of age and with over 1.1 million hospital discharges for heart failure in 2006. Of the over 1 million patients hospitalized each year with a primary diagnosis of heart failure, over 50% are readmitted to the hospital within 6 months of discharge. Heart failure is also a high mortality disease, with approxi matelyapproximately one-half of heart failure patients dying within five years of initial diagnosis.

Patient populations have been identified which have reduced levels of endogenous active natriuretic peptides, including endogenous active ANP. The reduced levels have a variety of causes, including mutations in endogenous natriuretic peptides and in enzymes necessary to convert natriuretic peptide sequences to their

active form. Patients with reduced levels of endogenous active natriuretic peptides are reported to have a poor response to current drug therapies and to have increased rates of cardiac remodeling and cardiac events.

We believe that PL-3994 has the potential to treat heart failure with preserved ejection fraction, or HF-PEF, which is a high unmet medical need with no approved treatment options, heart failure with reduced ejection fraction, or HF-REF, and patients with reduced levels of endogenous active natriuretic peptides, such as corin deficiencies, which is a high unmet medical need in patients with a poor response to current therapies, with the objective to restore normal natriuretic peptide function.

We have planned a repeat dose Phase 2 clinical trial in patients hospitalized with heart failure, which willHF-PEF, HF-REF and corin deficiency to evaluate safety profiles in patients given repeat doses of PL-3994and symptom relief as well as pharmacokinetic (period to metabolize or excrete the drug) and pharmacodynamic (period of action or effect of the drug) endpoints, but have not determined whenendpoints. Analysis will include cardiac imaging and measurement of left ventricular ejection fraction. Contingent on adequate available funds, we intend to initiate this trial will commence.

PL-3994 for Refractory Hypertension. PL-3994 may potentially also be used for treatmentin the first half of refractory or difficult-to-control hypertension, which is high blood pressure despitecalendar 2015 with data anticipated in the second half of 2015. Assuming favorable results from this trial, we have planned a three-drug regimen that includes a diuretic. Refractory hypertension is commonly foundrepeat dose Phase 2 proof-of-principle clinical trial in patients with congestive heart failure, or renal disease. While therewhich would involve treatment for a three to six month period, and would evaluate safety, cardiac function, effects on remodeling, symptom improvement and hospitalization admission rates. This trial will be initiated following completion of the first repeat dose Phase 2 clinical trial, with a targeted start of the second half of calendar 2015 with data anticipated by the second half of 2016.

Preclinical studies utilizing a “2 kidney, 1 clip” rat model of renovascular hypertension and cardiac hypertrophy have been conducted with PL-3994. Treatment with PL-3994 reduced both excess production of aldosterone and cardiac hypertrophy.

PL-3994 for Acute Exacerbations of Asthma.  Research over the past two decades has demonstrated potent bronchodilator effects with both systemic and inhalation administration of natriuretic peptides. NPR-A agonism is known to relax smooth muscles in airways and works through a pathway independent of the beta-2 adrenergic receptor. Preclinical testing demonstrated potent airway smooth muscle relaxation in guinea pig and human tissues using PL-3994, and animal studies in sensitized guinea pigs have demonstrated a bronchodilator effect with PL-3994 using both subcutaneous and inhalation administration.

Acute exacerbations of asthma, also called acute severe asthma, is an ongoing, unremitting asthma episode in which asthma symptoms do not adequately respond to initial bronchodilator therapy. Inhaled beta-2 adrenergic receptor agonists, such as albuterol, inhaled anticholinergic drugs, such as ipratropium, and systemic corticosteroids are primary treatments for episodes of acute exacerbations of asthma. Some patients with acute exacerbations of asthma become unresponsive to beta-2 adrenergic receptor agonists, significantly limiting treatment options and increasing risk. Patients who do not respond to initial therapy are at risk of severe complications. We intend to initially target PL-3994 as a large numbertreatment for those at-risk unresponsive patients.

Emergency room visits and hospitalizations due to asthma have remained stable from 2001 to 2009, with almost 1.7 million emergency room visits and 440,000 hospitalizations attributed to asthma in 2006. In 2008, approximately 23.3 million Americans had asthma, with a projected 2010 economic cost in the United States of approved drugs$20.7 billion, of which the largest single direct medical expenditure, $5.9 billion, is for treatment of hypertension, there are no approved drugs for hypertension that are active through the NPR-A system. Refractory and other difficult-to-control hypertension can be caused by increased aldosterone levels. PL-3994 is believed to act through the NPR-A system on the RAAS to decrease renin and aldosterone secretion and thereby decrease blood pressure. In a Phase 2A study of subjects with controlled hypertension, the data suggested an increased effect of PL-3994 in reducing systemic blood pressure when taken with an angiotensin-converting enzyme (ACE) inhibitor, a common class of drugs for controlling hypertension. PL-3994 thus may be suitable for use as an adjunct therapy to one or more existing hypertension drugs, including an ACE inhibitor.prescription drugs.

Clinical Studies with PL-3994.Preclinical studies in animals established a dose-dependent effect on blood pressure and diuresis, and in animal models of heart failure showed improved kidney function and prevention of cardiac hypertrophy.  Human clinical studies of PL-3994 commenced with a Phase 1 trial which concluded in the first quarter of calendar year 2008. This was a randomized, double-blind, placebo-controlled study in 26 healthy volunteers who received either PL-3994 or a placebo subcutaneously. The evaluations included safety, tolerability, pharmacokinetics and several pharmacodynamic endpoints, including levels of cGMP, a natural messenger nucleotide. Dosing concluded with the successful achievement of the primary endpoint o fof the study, a prespecified reduction in systemic blood pressure. No volunteer experienced a serious or severe adverse event. Elevations in plasma cGMP levels, increased diuresis and increased natriuresis were all observed for several hours after single subcutaneous doses.

In the second quarter of calendar year

Later in 2008, we conducted a Phase 2A trial in volunteers with controlled hypertension who were receiving one or more conventional antihypertensive medications. In this trial, which was a randomized, double-blind, placebo-controlled, single ascending dose study in 21 volunteers, the objective was to demonstrate that PL-3994 can be given safely to patients taking antihypertensive medications commonly used in heart failure and hypertension patients. Dosing concluded with the successful achievement of the primary endpoint

of the study, a prespecified reduction in systemic blood pressure. No volunteer experienced a serious or severe adverse event. Elevations in plasma cGMP levels were observed for several hours after single subcutaneous doses.
Based on the studies to date, PL-3994 is ready for Phase 2 safety and efficacy studies.

Administration of PL-3994.We are developing PL-3994 for acute exacerbations of asthma indications as either a subcutaneously administered drug or as an inhaled drug.  For asthma indications we believe that inhalation administration may be preferable to subcutaneous or other systemic administration.

We are developing PL-3994 for heart failure and refractory hypertension indications as a subcutaneously administered drug.we believe that subcutaneous administration of PL-3994 may be preferable. PL-3994 is well absorbed through thisthe subcutaneous route of administration. In human studies, the pharmacokinetic and pharmacodynamic half-lives were on the order of hours, significantly longer than the comparable half-lives of endogenous natriuretic peptides. We believe that subcutaneous PL-3994, if successful, will be amenable to self-administration by patients, similar to insulin and other self-administered drugs.
Other Natriuretic Peptide Receptor-Specific Programs. We have suspended work on our early stage discovery and development programs in the natriuretic peptide receptor field. We do not anticipate For asthma indications we believe that any significant effort willinhalation administration of PL-3994 may be devotedpreferable to these programs during the next twelve months.

We have suspended marketing, clinical trials and securing regulatory approvals of NeutroSpec, and do not anticipate conducting any substantive worksubcutaneous or incurring substantial expenditures on NeutroSpec over the next twelve months.
other systemic administration.

Technologies We Use

We used a rational drug design approach to discover and develop proprietary peptide, peptide mimetic and small molecule agonist compounds, focusing on melanocortin and natriuretic peptide receptor systems. Computer-aided drug design models of receptors are optimized based on experimental results obtained with peptides and small molecules that we develop, supported by conformational analyses of peptides in solution utilizing nuclear magnetic resonance spectroscopy. By integrating both technologies, we believe we are developing an advanced understanding of the factors which drive agonism.

We have developed a series of proprietary technologies used in our drug development programs. One technology employs novel amino acid mimetics in place of selected amino acids. These mimetics provide the receptor-binding functions of conventional amino acids while providing structural, functional and physiochemical advantages. The amino acid mimetic technology is employed in PL-3994, our compound in development for treatment of heart failure, acute exacerbations of asthma heart failure and refractory hypertension.

Some compound series have been derived using our proprietary and patented platform technology, called MIDAS™ (MIDASTM, orMetalIon-inducedDistinctiveArray ofStructures).tructures. This technology employs metal ions to fix the three-dimensional configuration of peptides, forming conformationally rigid molecules that remain folded specifically in their active state. These MIDAS molecules are generally simple to synthesize, are chemically and proteolytically stable, and have the potential to be orally bioavailable. In additio n,addition, MIDAS molecules are information-rich and provide data on structure-activity relationships that may be used to design small molecule, non-peptide drugs.

Competition

General.Our products under development will compete on the basis of quality, performance, cost effectiveness and application suitability with numerous established products and technologies. We have many competitors, including pharmaceutical, biopharmaceutical and biotechnology companies. Furthermore, there are several well-established products in our target markets that we will have to compete against. Products using new technologies which may be competitive with our proposed products may also be introduced by others. Most of the companies selling or developing competitive products have financial, technological, manufacturing and distribution resources significantly greater than ours and may represent significant competition for us.


30


In addition, if any of our product candidates are approved by FDA, they will eventually face competition from generic versions that will sell at significantly reduced prices, be preferred by managed care and health insurance payers, and be eligible for automatic pharmacy substitution even when a prescriber writes a prescription for our product. The timing and extent of future generic competition is dependent upon both our intellectual property rights and the FDA regulatory process, but cannot be accurately predicted.

The pharmaceutical and biotechnology industries are characterized by extensive research efforts and rapid technological change. Many biopharmaceutical companies have developed or are working to develop products similar to ours or that address the same markets. Such companies may succeed in developing technologies and products that are more effective or less costly than any of those that we may develop. Such companies may be more successful than us in developing, manufacturing and marketing products.

We cannot guarantee that we will be able to compete successfully in the future or that developments by others will not render our proposed products under development or any future product candidates obsolete or non-competitive or that our collaborators or customers will not choose to use competing technologies or products.

Bremelanotide and Other Melanocortin Recepetor Agonists for Treatment of Sexual Dysfunction.FSD.  There is competition and financial incentive to develop, market and sell drugs for the treatment of ED and FSD. Leading drugsFSD, for which there is no approved for ED indications are PDE-5 inhibitors which targetdrug in the vascular system, such as sildenafil (sold under the trade name Viagra®), vardenafil (sold under the trade name Levitra®) and tadalafil (sold under the trade name Cialis®). In addition, we are aware of other PDE-5 inhibitors under development. Other drugs approved for ED indications include alprostadil for injection (sold under the trade name Caverject Impulse® among others), which is injected directly into the penis, and alprostadil in urethral suppository format (sold under the trade name MUSE®). In addition, a variety of devices, including vacuum devices and surgical penile implants, have been approved for ED indications.United States. We are aware of several drugs at various stages of development, most of which are taken on a numberchronic, typically once-daily, basis. Flibanserin, a non-hormone oral serotonin 5-HT1A agonist, 5-HT2A antagonist that requires chronic dosing, has been investigated for treatment of premenopausal women with hypoactive sexual desire disorder. In the initial submission to FDA, following a negative advisory panel, it was determined that flibanserin failed to meet its co-primary endpoint of daily change of desire. Following two NDA review cycles with the FDA and a formal dispute resolution proceeding, the FDA has required additional safety studies. An oral fixed-dose combination of two antidepressants, bupropion and trazodone, is reported to be entering Phase 2 studies in premenopausal women with hypoactive sexual desire disorder. Another company is developing two different oral fixed-dose combination drugs, one a combination of sildenafil and testosterone and the other a combination of testosterone and buspirone hydrochloride, and is conducting Phase 2 studies in premenopausal women with hypoactive sexual desire disorder. Libigel®, a testosterone gel, completed two Phase 3 efficacy trials for treatment of FSD in surgically post-menopausal women, but did not show statistical separation from placebo in those trials. Intrinsa®, a transdermal testosterone patch, successfully completed a Phase 3 clinical program, but was not approved based on long-term use safety risks of cancer and cardiovascular adverse events. There are other companies reported to be developing new drugs for EDFSD indications, including at least one company developing a new drug for treatment of ED not sufficiently responsive to PDE-5 inhibitors, some of which aremay be in clinical trials in the United States andor elsewhere. We are not aware of any company actively developing a melanocortin receptor agonist drug for ED.

There are no products specifically approvedFSD.

companies developing intravenously administered natriuretic peptide drugs, with at least one reported to have completed Phase 2 clinical trials for acute heart failure. Novartis AG has reported clinical trial results with a combination drug, LCZ696, which inhibits both the angiotensin II receptor and neprilysin (an enzyme which inactivates endogenous active natriuretic peptides). LZC696 results in increases of endogenous active ANP levels, and thus has a mechanism of action with similarities to PL-3994. In a Phase 3 trial, LZC696 was compared to an angiotensin-converting-enzyme inhibitor, enalapril, in heart failure patients with reduced ejection fraction. It significantly improved the rate of death from cardiovascular causes, significantly reduced hospitalization for heart failure and significantly improved heart failure symptoms. LZC696 clearly demonstrated that upregulation of the natriuretic peptide system in combination with angiotensin-converting-enzyme inhibition is superior to angiotensin-converting-enzyme inhibition alone, and thus provides validation of the natriuretic peptide system as a target for improving outcomes in treating heart failure patients. In addition, there are a number of approved drugs and drugs in development for treatment of heart failure through mechanisms or pathways other than agonism of NPR-A.

PL-3994 for Acute Exacerbations of Asthma Indications.  The asthma market is intensively competitive, with substantial competition and financial incentive to develop, market and sell drugs for treatment of asthma, with projected costs of prescription drugs of $5.9 billion in the United States in 2010. We are aware of companies developing drugs for the specific indications of either acute exacerbations of asthma or acute severe asthma, including at least one company with a drug reported to be currently in clinical trials. Certain of these drugs under development work by mechanisms of action different from the mechanisms of action of currently approved products. In addition, a number of clinical trials are conducted by hospitals, research institutes and others exploring various methods and combinations of drugs to treat acute exacerbations of asthma. There are a number of drug sdrugs and therapies currently used to treat acute exacerbations of asthma, including administration of oral or intravenous systemic steroids, use of oxygen or heliox, a mixture of helium and oxygen, nebulized short-acting beta-2 adrenergic receptor agonists, intravenous or nebulized anticholinergic agents and, for patients in or approaching respiratory arrest, intubation and mechanical ventilation. However, each of these drugs or therapies has recognized limitations or liabilities, and we believe that there remains an unmet medical need for a safe and effective treatment for acute exacerbations of asthma. We are not aware of any other company actively developing a drug to relax smooth muscles in airways throughtreat asthma using a natriuretic peptide receptor pathway.

Carperitide, a recombinant human atrial natriuretic peptide drug, is marketed in Japan and is reported to be available for licensing in other countries. Ularitide, a synthetic form of urodilatin, a naturally occurring human natriuretic peptide related to atrial natriuretic peptide, is reported to be in clinical trials. Nesiritide, carperitide and ularitide are admini stered by intravenous infusion. Because of the very short half-lives of nesiritide, carperitide and ularitide, we believe these drugs are unlikely to be suitable for subcutaneous administration or for long-term treatment of heart failure.elsewhere.

In the event that a third party has also filed a patent application relating to an invention we claimed in a patent application, we may be required to participate in an interference proceeding adjudicated by the United States Patent and Trademark Office to determine priority of invention. The possibility of an interference proceeding could result in substantial uncertainties and cost, even if the eventual outcome is favorable to us. An adverse outcome could result in the loss of patent protection for the subject of the interference, subjecting us to significant liabilities to third parties, the need to obtain licenses from third parties at undetermined cost, or requiring us to cease using the technology.

Future Patent Infringement.Infringement.  We do not know for certain that our commercial activities will not infringe upon patents or patent applications of third parties, some of which may not even have been issued. Although we are not aware of any valid United States patents which are infringed by bremelanotide or PL-3994, we cannot exclude the possibility that such patents might exist or arise in the future. We may be unable to avoid infringement of any such patents and may have to seek a license, defend an infringement action, or challenge the validity of such patents in court. Patent litigation is costly and time consuming. If such patents are valid and we do not obtain a license under any such patents, or we are found liable for infringement, we may be liable for significant monetary damag es,damages, may

encounter significant delays in bringing products to market, or may be precluded from participating in the manufacture, use or sale of products or methods of treatment covered by such patents.

Proprietary Information.Information.  We rely on proprietary information, such as trade secrets and know-how, which is not patented. We have taken steps to protect our unpatented trade secrets and know-how, in part through the use of confidentiality and intellectual property agreements with our employees, consultants and certain contractors. If our employees, scientific consultants, collaborators or licensees develop inventions or processes independently that may be applicable to our product candidates, disputes may arise about the ownership of proprietary rights to those inventions and processes. Such inventions and processes will not necessarily become our property, but may remain the property of those persons or their employers. Protracted and costly litigation could be necessary to enforce and determine the scope of our proprietary rights.

If trade secrets are breached, our recourse will be solely against the person who caused the secrecy breach. This might not be an adequate remedy to us because third parties other than the person who causes the breach will be free to use the information without accountability to us. This is an inherent limitation of the law of trade secret protection.

U.S. Governmental Regulation

The FDA, comparable agencies of Pharmaceutical Products

General

Regulation by governmental authorities in the United States and other countries will have a significant impact on our research, product development, manufacturing and state regulatory authorities have establishedmarketing of any pharmaceutical products. The nature and the extent to which regulations and guidelines which apply to us will vary depending on the nature of any such products. Our potential pharmaceutical products will require regulatory approval by governmental agencies prior to commercialization. The products we are developing are subject to federal regulation in the United States, principally by the FDA under the Federal Food, Drug, and Cosmetic Act, or FFDCA, and by state and local governments, as well as regulatory and other authorities in foreign governments that include rigorous preclinical and clinical testing and other approval procedures. Such regulations govern or influence, among other things, the clinicalresearch, development, testing, manufacturing,manufacture, safety and efficacy requirements, labeling, storage, record keeping,recordkeeping, licensing, advertising, promotion, marketingdistribution and distribution of our proposed products. Noncompliance with applicable requirements can result in fines, recalls or seizuresexport of products, total or partial suspension of production, refusal ofmanufacturing and the regulatory authoritiesmanufacturing process. In many foreign countries, such regulations also govern the prices charged for products under their respective national social security systems and availability to approve marketing applications, withdrawal of approvals and criminal prosecution.

Before a drug product is approvedconsumers.

All drugs intended for human use are subject to rigorous regulation by the FDA in the United States and similar regulatory bodies in other countries. The steps ordinarily required by the FDA before an innovative new drug product may be marketed in the United States are similar to steps required in most other countries and include, but are not limited to:

completion of preclinical laboratory tests, preclinical animal testing and formulation studies;
submission to the FDA of an IND, which must be in effect before clinical trials may commence;
submission to the FDA of an NDA that includes preclinical data, clinical trial data and manufacturing information;
payment of substantial user fees for commercial marketing, three phasesfiling the NDA and other recurring user fees;
FDA review of the NDA;
satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities; and
FDA approval of the NDA, including approval of all product labeling.

For combination products deemed to have a “drug” primary mode of action, primary review of the product will be conducted by the appropriate division within the Center for Drug Evaluation and Research, or CDER, but CDER will consult with the Center for Devices and Radiological Health, or CDRH, to ensure that the device components of the product meet all applicable device requirements.

The research, development and approval process requires substantial time, effort and financial resources, and approvals may not be granted on a timely or commercially viable basis, if at all.

Preclinical testing includes laboratory evaluations to characterize the product’s composition, impurities, stability, and mechanism of its pharmacologic effect, as well as animal studies to assess the potential safety and efficacy of each product. Preclinical safety tests must be conducted by laboratories that comply with FDA regulations regarding Good Laboratory Practices, or GLP, and the U.S. Department of Agriculture’s Animal Welfare Act. Violations of these laws and regulations can, in some cases, lead to invalidation of the tests, requiring such tests to be repeated and delaying approval of the NDA. The results of the preclinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of an IND and are reviewed by the FDA before the commencement of human clinical trials. Unless the FDA objects to an IND by placing the study on clinical hold, the IND will go into effect 30 days following its receipt by the FDA. The FDA may authorize trials only on specified terms and may suspend ongoing clinical trials at any time on various grounds, including a finding that patients are being exposed to unacceptable health risks. If the FDA places a study on clinical hold, the sponsor must resolve all of the FDA’s concerns before the study may begin or continue. The IND application process may become extremely costly and substantially delay development of products. Similar restrictive requirements also apply in other countries. Additionally, positive results of preclinical tests will not necessarily indicate positive results in clinical trials.


TABLE OF CONTENTS

Clinical trials involve the administration of the investigational product to humans under the supervision of qualified principal investigators. Our clinical trials must be conducted in accordance with Good Clinical Practice, or GCP, regulations under protocols submitted to the FDA as part of an IND. In addition, each clinical trial is approved and conducted under the auspices of an IRB, and requires the patients’ informed consent. The IRB considers, among other things, ethical factors, the safety of human subjects, and the possibility of liability of the institutions conducting the trial. The IRB at each institution at which a clinical trial is being performed may suspend a clinical trial at any time for a variety of reasons, including a belief that the test subjects are being exposed to an unacceptable health risk. As the sponsor, we can also suspend or terminate a clinical trial at any time.

Clinical trials are usuallytypically conducted to test the safetyin three sequential phases, Phases 1, 2, and effectiveness3, involving an increasing number of the product.human subjects. These phases may sometimes overlap or be combined. Phase 1 clinical trials most typically involve testing the drug onare performed in a small number of healthy volunteershuman subjects or subjects with the targeted condition, and involve testing for safety, dosage tolerance, absorption, distribution, metabolism and excretion. Phase 2 studies, which may involve up to assesshundreds of subjects, seek to identify possible adverse effects and safety risks, preliminary information related to the safety profileefficacy of the drugproduct for specific targeted diseases, dosage tolerance, and optimal dosage. Finally, Phase 3 trials may involve up to thousands of individuals often at different dosage levels. Phase 2geographically dispersed clinical trials, which may also enroll a relatively small number of patient volunteers,trial sites, and are designed to further evaluate the drug’s safety profile andintended to provide preliminarythe documentation of effectiveness and important additional safety data asrequired for approval. Prior to the drug’s effectiveness in humans.commencing Phase 3 clinical trials consistmany sponsors elect to meet with FDA officials to discuss the conduct and design of larger, well-controlledthe proposed trial or trials.

In addition, federal law requires the listing, on a publicly-available website, of detailed information on clinical trials for investigational drugs. Some states have similar or supplemental clinical trial reporting laws.

Success in early-stage animal studies and clinical trials does not necessarily assure success in later-stage clinical trials. Data obtained from animal studies and clinical activities are not always conclusive and may be subject to alternative interpretations that may involve several hundredcould delay, limit or thousand patient volunteers representingeven prevent regulatory approval.

All data obtained from the drug’s targeted population. Duringpreclinical studies and clinical trials, in addition to detailed information on the manufacture and composition of the product, would be submitted in an NDA to the FDA for review and approval for the manufacture, marketing and commercial shipments of any of these phases,our products. FDA approval of the NDA is required before commercial marketing or non-investigational interstate shipment may begin in the United States. The FDA may also conduct an audit of the clinical trial can be placed on clini cal hold, or temporarily or permanently stopped for a variety of reasons, principally for safety concerns.

After approving a product for marketing,data used to support the NDA.

With regard to an NDA, the FDA may require post-marketing testing, including extensive Phase 4 studies, and surveillance to monitordeny or delay approval of an application that does not meet applicable regulatory criteria, e.g., if the FDA determines that the preclinical or clinical data or the manufacturing information does not adequately establish the safety and effectivenessefficacy of the product in general use.drug. The FDA has substantial discretion in the approval process and may withdrawdisagree with an applicant’s interpretation of the data submitted in its NDA. The FDA can request additional information, seek clarification regarding information already provided in the submission or ask that new additional clinical trials be conducted, all of which can delay approval. Similar types of regulatory processes will be encountered as efforts are made to market any drug internationally. We will be required to assure product approvalsperformance and manufacturing processes from one country to another.

Even if the FDA approves a product, it may limit the approved uses for the product as described in the product labeling, require that contraindications, warning statements or precautions be included in the product labeling, require that additional studies be conducted following approval as a condition of the approval, impose restrictions and conditions on product distribution, prescribing or dispensing in the form of a REMS, or otherwise limit the scope of any approval or limit labeling. Once it approves an NDA, the FDA may revoke or suspend the product approval if compliance with post-market regulatory standards is not maintained or if problems occur following initial marketing.after the product reaches the marketplace. In addition, the FDA may impose restrictionsrequire post-marketing studies to monitor the effect of approved products, and may limit further marketing of the product based on the useresults of a drug that may limit its marketing potential.these post-market studies.

TABLE OF CONTENTS

Pharmaceutical manufacturers, distributors and their subcontractors are required to obtaining approval of an NDA fromregister their facilities with the FDA for any of our proposed products, any facility that manufactures such a product must complyand state agencies, and manufacturers are required to list their marketed drugs with GMPs. This means, among other things, that the drug manufacturing establishment must be registered with, and subject to inspection by, the FDA. Foreign manufacturing establishments must also comply with GMPsFDA, and are subject to periodic inspection by the FDA or by corresponding regulatory agencies in suchand other countries under reciprocal agreementsauthorities, where applicable, and must comply with the FDA. In complyingFDA’s current Good Manufacturing Practices, or GMP, regulations, and the product specifications set forth in the approved NDA. The GMP requirements for pharmaceutical products are extensive and compliance with them requires considerable time, resources and ongoing investment. The regulations require manufacturers and suppliers of raw materials and components to establish validated systems and to employ and train qualified employees to ensure that products meet high standards establishedof safety, efficacy, stability, sterility (where applicable), purity, and potency. The requirements apply to all stages of the manufacturing process, including the synthesis, processing, sterilization, packaging, labeling, storage and shipment of the drug product. For all drug products, the regulations require investigation and correction of any deviations from GMP requirements and impose documentation requirements upon us and any third-party manufacturers that we may decide to use. Manufacturing establishments are subject to mandatory user fees, and to periodic unannounced inspections by the FDA and state agencies for compliance with all GMP requirements. The FDA is authorized to inspect manufacturing establishments must continue to expend time, moneyfacilities without a warrant at reasonable times and effort in the areas of production and quality control to ensure full technical compliance. a reasonable manner.

We will use contract manufacturing establishments, in the United States or in foreign countries, to manufacture our pro posed products, and will depend on those establishmentspresent or future suppliers may not be able to comply with GMPsGMP and other FDA regulatory requirements. Failure to comply with the statutory and regulatory requirements subjects the manufacturer and/or the NDA sponsor or distributor to possible legal or regulatory action, such as a delay or refusal to approve an NDA, suspension of manufacturing, seizure or recall of a product, or civil or criminal prosecution of the company or individual officers or employees.

Post-Marketing Regulation

Any drug products manufactured or distributed by us pursuant to FDA approvals, as well as the materials and components used in our products, are subject to pervasive and continuing regulation by the FDA, including:

recordkeeping requirements;
periodic reporting requirements;
GMP requirements related to all stages of manufacturing, testing, storage, packaging, labeling and distribution of finished dosage forms of the product;
monitoring and reporting of adverse experiences with the product; and
advertising and promotional reporting requirements and restrictions.

Adverse experiences with the product must be reported to the FDA and could result in the imposition of market restriction through labeling changes or product removal. Product approvals may be revoked if compliance with regulatory requirements is not maintained or if problems concerning safety or effectiveness of the product occur following approval. The FDA is developing a national electronic drug safety tracking system known as SENTINEL that may impose additional safety monitoring burdens, and enhanced FDA enforcement authority, beyond the extensive requirements already in effect. As a condition of NDA approval, the FDA may require post-approval testing and surveillance to monitor a product’s safety or efficacy. The FDA also may impose other conditions, including labeling restrictions which can materially impact the potential market and profitability of a product.

With respect to post-market product advertising and promotion, the FDA and other government agencies including the Department of Health and Human Services and the Department of Justice, and individual States, impose a number of complex regulations on entities that advertise and promote pharmaceuticals, including, among others, standards and restrictions on direct-to-consumer advertising, off-label promotion, industry-sponsored scientific and educational activities and promotional activities involving the Internet. The FDA has very broad enforcement authority under the FFDCA, and failure to abide by these regulations can result in administrative and judicial enforcement actions, including the issuance of a Warning Letter directing correction of deviations from FDA standards, a requirement that future advertising and promotional materials be pre-cleared by the FDA, False Claims Act prosecution based on alleged off-label marketing seeking monetary and other penalties, including potential exclusion of the drug and/or the company from participation in government health care programs, and state and federal civil and criminal investigations and prosecutions.


TABLE OF CONTENTS

Foreign regulatory bodies also strictly enforce these and other regulatory requirements.requirements and drug marketing may be prohibited in whole or in part in other countries.

We, our collaborators or our third-party contract manufacturers may not be able to comply with the applicable regulations. After regulatory approvals are obtained, the subsequent discovery of previously unknown problems, or the failure to maintain compliance with existing or new regulatory requirements, may result in:

restrictions on the marketing or manufacturing of a product;
Warning Letters or Untitled Letters from the FDA asking us, our collaborators or third-party contractors to take or refrain from taking certain actions;
withdrawal of the product from the market;
the FDA’s refusal to approve pending applications or supplements to approved applications;
voluntary or mandatory product recall;
fines or disgorgement of profits or revenue;
suspension or withdrawal of regulatory approvals;
refusals to permit the import or export of products;
product seizure; and
injunctions or the imposition of civil or criminal penalties.

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. 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 are subject to 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:

the federal Anti-Kickback Statute, which prohibits, among other things, any person or entity from knowingly and willfully offering, soliciting, receiving or providing any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce either the referral of an individual or in return for the purchase, lease, or order of any good, facility item or service, for which payment may be made, in whole or in part, under federal healthcare programs such as the Medicare and Medicaid programs;
federal civil and criminal false claims laws and civil monetary penalty laws, including, for example, the federal civil False Claims Act, which impose criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for, among other things, knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payer (e.g., public or private), knowingly and willfully embezzling or stealing from a health care benefit program, willfully obstructing a criminal investigation of a health care offense and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and their implementing regulations, which impose obligations on covered entities, including healthcare providers, health plans, and healthcare clearinghouses, as well as their respective business

associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;
the federal physician sunshine requirements under the Affordable Care Act, which require manufacturers of drugs, devices, biologics and medical supplies to report annually to the Centers for Medicare & Medicaid Services information related to payments and other transfers of value provided to physicians and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members; and
state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payer, including commercial insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government, or otherwise restrict payments that may be provided to healthcare providers and other potential referral sources; state laws that require drug manufacturers to report information related to payments and other transfers of value to healthcare providers or marketing expenditures; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

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, amended the intent requirement of the federal Anti-Kickback Statute and certain 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 provided 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 federal civil 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 administrative, civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual 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.

Generic Competition

Orange Book Listing.  In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent whose claims cover the applicant’s product. Upon approval of a drug, the applicant identifies all patents that claim the approved product’s active ingredient(s), the drug product’s approved formulation, or an approved method of use of the drug. Each of the identified patents are then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application, or ANDA. An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been shown through bioequivalence testing, unless such testing is waived by the FDA, as is the case with some injectable drug products, to be therapeutically equivalent to the listed drug. Other than bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, preclinical or clinical tests to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug, and can usually be substituted by pharmacists under prescriptions written for the original listed drug.

The ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book. Specifically, the applicant must certify either that: (1) the required patent


 

TABLE OF CONTENTS

information has not been filed (a Paragraph I Certification); (2) the listed patent has expired (a Paragraph II Certification); (3) the listed patent has not expired, but will expire on a particular date and the generic approval is being sought only after patent expiration (a Paragraph III Certification); or (4) the listed patent is invalid, unenforceable, or will not be infringed by the proposed generic product (a Paragraph IV Certification). In certain circumstances, the ANDA applicant may also elect to submit a “section (viii)” statement instead of a Paragraph IV Certification, certifying that its proposed ANDA label does not contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. If the application contains only Paragraph I or Paragraph II Certifications, the ANDA may be approved as soon as FDA completes its review and concludes that all approval requirements have been met. If the ANDA contains one or more Paragraph III Certifications, the ANDA cannot not be approved until each listed patent for which a Paragraph III Certification was filed have expired.

If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA holder and patent owner once the ANDA has been accepted for filing by the FDA. The patent owner or NDA holder may then commence a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months (the “30-month stay”), expiration of the patent, settlement of the lawsuit in which the patent owner admits that the patent is invalid or not infringed by the ANDA product, or a decision in the infringement case that holds the patent to be invalid or not infringed, or an order by the court shortening the 30-month stay due to actions by the patent holder to delay the litigation. In most circumstances, NDA holder is only eligible for one 30-month stay against an ANDA.

If a patent infringement action is filed against an ANDA applicant, any settlement of the litigation must be submitted to the Federal Trade Commission, or the FTC. If FTC believes the terms or effects of the settlement are anticompetitive, FTC may bring an antitrust enforcement action against the parties. Private parties may also bring antitrust lawsuits against drug companies based on such patent litigation settlements.

The ANDA also will not be approved until any applicable non-patent regulatory exclusivity listed in the Orange Book for the referenced product has expired.

Regulatory Exclusivity.  Upon NDA approval of a new chemical entity or NCE, which is a drug that contains no active moiety that has been approved by the FDA in any other NDA, that drug receives five years of marketing exclusivity during which the FDA cannot receive for review any ANDA seeking approval of a generic version of that drug. An ANDA containing a Paragraph IV Certification may be received by FDA 4 years after the NCE drug’s approval, but any 30-month stay that ensues would be extended so that it expires seven and one half years after the NCE approval date, subject to early termination by reason of a court decision or settlement as described above.

Certain changes to an NDA drug, such as the addition of a new indication to the package insert, for which new clinical trials, conducted or sponsored by the applicant are deemed by FDA to be essential to the approval of the change, can be eligible for a three-year period of exclusivity during which the FDA cannot approval an ANDA for a generic drug that includes the change. An ANDA that contains a section (viii) statement to a method of use patent may be approved with labeling that omits the patented use before the use patent expires. Generic drugs approved with such a labeling carve out may be substituted by pharmacists for the original branded drug before the method of use patent expires.

Section 505(b)(2) New Drug Applications.  Most drug products obtain FDA marketing approval pursuant to an NDA or an ANDA. A third alternative is a special type of NDA, commonly referred to as a 505(b)(2) NDA, which enables the applicant to rely, in part, on the FDA’s previous approval of a similar product, or published literature, in support of its application.

505(b)(2) NDAs often provide an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. A 505(b)(2) NDA may be used 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. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate, it may eliminate the need to conduct certain preclinical or


TABLE OF CONTENTS

clinical studies of the new product. The FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new product candidate for all, or some, of the label indications for which the referenced product has been approved, as well as for any new indication or conditions of use sought by the Section 505(b)(2) applicant.

To the extent that the Section 505(b)(2) applicant is relying on studies conducted for an already approved product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would. Thus approval of a 505(b)(2) NDA can be stalled until all the listed patents claiming the referenced product have expired, until any non-patent exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed in the Orange Book for the referenced product has expired, and, in the case of a Paragraph IV certification and subsequent patent infringement suit, until the expiration of any 30-month stay, subject to early termination of the stay as described above.

Changing Legal and Regulatory Landscape

Periodically legislation is introduced in the U.S. Congress that could change the statutory and regulatory provisions governing the approval, manufacturing and marketing of our drugs. In addition, the FDCA, FDA regulations and guidance are often revised or reinterpreted by the FDA or the courts in ways that may significantly affect our business and products. We cannot predict whether or when legislation or court decisions impacting our business will be enacted or issued, what FDA regulations, guidance or interpretations may change, or what the impact of such changes, if any, may be in the future.

Third-Party Reimbursements

Successful sales of our proposed products in the United States and other countries will depend, in large part, on the availability of adequate reimbursement from third-party payorspayers such as governmental entities, managed care organizations, health maintenance organizations, or HMOs, and private insurance plans. Reimbursement by a third-party payor may dependpayer depends on a number of factors, including the payor’spayer’s determination that the product has been approved by the FDA for the indication for which the claim is being made, that it is neither experimental nor investigational, and that the use of


33


the product is safe and efficacious, medically necessary, appropriate for the specific patient and cost effective.

Since reimbursement by one payorpayer does not guarantee reimbursement by another, we or our licensees may be required to seek approval from each payorpayer individually. Seeking such approvals is a time-consuming and costly process. Third-party payorspayers routinely limit the products that they will cover and the amount of money that they will pay and, in many instances, are exerting significant pressure on medical suppliers to lower their prices.

Payers frequently employ a tiered system in reimbursing end users for pharmaceutical products, with tier designation affecting copay or deductible amounts. There are no approved products for treating FSD, and thus is significant uncertainty concerning third-party reimbursement for the useextent and scope of any pharmaceutical product incorporating new technology and we are not sure whether third-party reimbursement will be available for our proposed products once approved, or that the reimbursement, if obtained, wil l be adequate. There is also significant uncertainty concerning third-party reimbursement for products treating FSD. Based on third-party reimbursement for approved products treating ED, we believe bremelanotide will be classified as a Tier 3 drug, so that reimbursement will be limited for bremelanotide for treatment of FSD, and ED.assuming the product is approved by the FDA. Less than full reimbursement by governmental and other third-party payors for our proposed products wouldpayers may adversely affect the market acceptance of these proposed products.bremelanotide. Further, healthcare reimbursement systems vary from country to country, and we are not sure whether third-party reimbursement willmight not be made available for our proposed productsbremelanotide for FSD under any other reimbursement system.

Manufacturing and Marketing

To be successful, our proposed products will need to be manufactured in commercial quantities under GMPs prescribed by the FDA and at acceptable costs. We do not have the facilities to manufacture any of our proposed products under GMPs. We intend to rely on collaborators, licensees or contract manufacturers for the commercial manufacture of our proposed products.

Our bremelanotide product candidate is a synthetic peptide. While the production process involves well-established technology, there are few manufacturers capable of scaling up to commercial quantities under GMPs at acceptable costs. We have identified one third-party manufacturer for the production of


TABLE OF CONTENTS

bremelanotide, Lonza Ltd., and have validated manufacturing of the bremelanotide drug substance under GMPs with that manufacturer. However, we have not negotiatedWe are in the process of negotiating a long-term supply agreement with the third-party manufacturer,Lonza, and may not be able to enter into a supply agreement on acceptable terms, if at all.

Our bremelanotide product candidate will be a combination product, incorporating both the bremelanotide drug substance and a delivery device. We will rely on a third-party manufacturer, Ypsomed AG, to make the delivery device and to ensure its and the device’s continued compliance with all FDA medical device regulations. We have selected an autoinjector delivery device, and are negotiating a long-term supply and manufacturing agreement, but may not be able to enter into such an agreement on acceptable terms, if at all. A third-party contract manufacturer, Catalent Belgium S.A., performs fill, finish and packaging of our bremelanotide product candidate. We are negotiation a long-term commercial supply agreement, but may not be able to enter into such an agreement on acceptable terms, if at all.

Our PL-3994 product candidate is a peptide mimetic molecule, incorporating a proprietary amino acid mimetic structure and amino acids. We have identified a manufacturer which made the product in quantities sufficient for Phase 1, and some anticipated Phase 2 clinical trials, and are in the process of evaluating commercial-scale manufacturers. Scaling up to commercial quantities may involve production, purification, formulation and other problems not present in the scale of manufacturing done to date.

Certain of our melanocortin receptor

Our MC1r and MC4r agonist product candidatecandidates are synthetic peptides, which we have primarily manufactured in-house.only at laboratory scale. We have not contracted with a third-party manufacturer to produce these synthetic peptides for either clinical trials or commercial purposes. While the production process involves well-established technology, there are few manufacturers capable of scaling up to commercial quantities under GMPs at acceptable costs. Additionally, scaling up to commercial quantities may involve production, purification, formulation and other problems not present in the scale of manufacturing done to date.

The failure of any manufacturer or supplier to comply with FDA regulations, including GMPs or medical device QSR, or to supply the device component or drug substance and services as agreed, would force us to seek alternative sources of supply and could interfere with our ability to deliver product on a timely and cost effective basis or at all. Establishing relationships with new manufacturers or suppliers, any of whom must be FDA-approved, is a time-consuming and costly process.

Product Liability and Insurance

Our business may be affected by potential product liability risks which are inherent in the testing, manufacturing, marketing and use of our proposed products. We have liability insurance providing up to $10 million coverage in the aggregate as to certain clinical trial risks.

Employees

As of October 28, 2010,21, 2014, we employed 3017 persons full time, of whom 1911 are engaged in research and development activities and 116 are engaged in administration and management.

Unless a director resigns, all directors hold office until the next annual meeting of stockholders or until their successors have been duly elected and qualified. Directors serve as members of committees as the board determines from time to time.

Director Independence

The board of directors has determined that all of the directors except for Dr. Spana (our chief executive officer and president) are independent directors and committee members, as defined in the NYSE AmexMKT listing standards.

There are no family relationships among any of our directors or executive officers.

The Board And Its Committees

Our board of directors has an audit committee, a compensation committee and a nominating and corporate governance committee.

Audit Committee

The audit committee reviews the engagement of the independent registered public accounting firm and reviews the independence of the independent registered public accounting firm. The audit committee also reviews the audit and non-audit fees of the independent registered public accounting firm and the adequacy of our internal control procedures. The audit committee is currently composed of four non-employee directors, Mr. deVeer (chair) and Drs. Taber, Molinoff and Dunton. The board has determined that the members of the audit committee are independent, as defined in the listing standards of the NYSE MKT, and satisfy the requirements of the NYSE MKT as to financial literacy and expertise. The board has determined that at least one member

TABLE OF CONTENTS

of the committee, Mr. deVeer, is the audit committee financial expert as defined by Item 407 of Regulation S-K. The responsibilities of the audit committee are set forth in a written charter adopted by the board and updated as of October 1, 2013, a copy of which is available on our website atwww.palatin.com.

Compensation Committee

The compensation committee reviews and recommends to the board on an annual basis employment agreements and compensation for our officers, directors and some employees, and administers our 2011 Plan and the options still outstanding which were granted under previous stock option plans. The compensation committee is composed of Mr. deVeer and Drs. Horovitz, Taber (chair) and Dunton. The board has determined that the members of the compensation committee are independent, as defined in the listing standards of the NYSE MKT. Our chief executive officer aids the compensation committee by providing annual recommendations regarding the compensation of all executive officers, other than himself. Our chief financial officer supports the committee in its work by gathering, analyzing and presenting data on our compensation arrangements and compensation in the marketplace. The responsibilities of the compensation committee are set forth in a written charter adopted by the board effective October 1, 2013, a copy of which is available on our website at www.palatin.com. The committee administers our 2011 Plan, under which it has delegated to an officer its authority to grant stock options to employees and to a single-member committee of the board its authority to grant restricted stock units to officers and to grant options and restricted stock units to our consultants, but in either instance not to grant options or restricted stock units to themselves, any member of the board or officer, or any person subject to Section 16 of the Exchange Act.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee assists the board in recommending nominees for directors, and in determining the composition of committees. It also reviews, assesses and makes recommendations to the board concerning policies and guidelines for corporate governance, including relationships of the board, the stockholders and management in determining our direction and performance. The responsibilities of the nominating and corporate governance committee are set forth in a written charter adopted by the board and updated as of October 1, 2013, a copy of which is available on our website at www.palatin.com. The nominating and corporate governance committee is composed of Mr. Hull, Ms. Rossetti and Drs. Horovitz (chair) and Molinoff, each of whom meets the independence requirements established by the NYSE MKT.

Board Role In Risk Oversight

Our board, as part of its overall responsibility to oversee the management of our business, considers risks generally when reviewing our strategic plan, financial results, business development activities, legal and regulatory matters. The board satisfies this responsibility through regular reports directly from our officers responsible for oversight of particular risks. The board’s risk management oversight also includes full and open communications with management to review the adequacy and functionality of the risk management processes used by management. The board’s role in risk oversight has no effect on the board’s leadership structure. In addition, committees of the board assist in its risk oversight responsibility, including:

The audit committee assists the board in its oversight of the integrity of the financial reporting and our compliance with applicable legal and regulatory requirements. It also oversees our internal controls and compliance activities, and meets privately with representatives from our independent registered public accounting firm.
The compensation committee assists the board in its oversight of risk relating to compensation policies and practices. The compensation committee annually reviews our compensation policies, programs and procedures, including the incentives they create and mitigating factors that may reduce the likelihood of excessive risk taking, to determine whether they present a significant risk to our company.

Board Leadership Structure

Since 2000, the roles of chairman of the board and chief executive officer have been held by separate persons. John K.A. Prendergast, Ph.D., a non-employee director, has served as chairman of the board since June 2000. Carl Spana, Ph.D., has been our chief executive officer and president since June 2000. Generally, the chairman


 

TABLE OF CONTENTS

is responsible for advising the chief executive officer, assisting in long-term strategic planning, and presiding over meetings of the board, and the chief executive officer is responsible for leading our day-to-day performance. While we do not have a written policy with respect to separation of the roles of chairman of the board and chief executive officer, the board believes that the existing leadership structure, with the separation of these roles, provides several important advantages, including: enhancing the accountability of the chief executive officer to the board; strengthening the board’s independence from management; assisting the board in reaching consensus on particular strategies and policies; and facilitating robust director, board, and executive officer evaluation processes.

Code Of Corporate Conduct And Ethics

We have adopted a code of corporate conduct and ethics, updated as of October 1, 2013, that applies to all of our directors, officers and employees, including our chief executive officer and chief financial officer. You can view the code of corporate conduct and ethics at our website,www.palatin.com. We will disclose any amendments to, or waivers from, provisions of the code of corporate conduct and ethics that apply to our directors, principal executive and financial officers in a current report on Form 8-K, unless the rules of the NYSE MKT permit website posting of any such amendments or waivers.

Executive Officers

Executive officers are appointed by the board and serve at the discretion of the board. Each officer holds his position until his successor is appointed and qualified. The current executive officers hold office under employment agreements.

Stock Option and Restricted Stock Unit Grants

In October 2006, we granted 37,500, 30,000 and 30,000 restricted stock units to Dr. Spana, Mr. Wills and Dr. Hallam, respectively, which vested on March 26, 2010.

The terms of these restricted stock units require that each executive retain ownership of at least 33% of the vested stock for the duration of the executive’s employment with us unless there is a change in control or for hardship as determined by the board of directors. In connection with the grant of the restricted stock units to our executive officers in October 2006, we determined at that time that the executive officers would not receive any further stock options or stock awards during the remainder of fiscal 2007 or the next three fiscal years thereafter, subject, however, to annual review by the Compensation Committee, which is authorized to make additional grants i f warranted based on market conditions, our common stock price, the need to retain our executive officers and the interests of our stockholders.

In fiscal 2008, the Compensation Committee determined that additional stock option grants were necessary in order to motivate and retain our executive officers, and on March 26, 2008, Dr. Spana, Mr. Wills and Dr. Hallam were granted options to purchase 37,500, 30,000 and 30,000 shares of common stock, respectively, vesting over four years. Twenty-five percent of the shares underlying each option were granted at an exercise price in excess of the fair market value on the date of grant in order to incentivize the executive to improve our financial condition.
In each of fiscal 2009 and 2010, the Compensation Committeecompensation committee determined that additional equity grants were necessary in order to motivate and retain our executive officers. Effective on each of July 1, 2008 and July 1, 2009, Dr. Spana, Mr. Wills and Dr. Hallam were granted options to purchase 25,000, 20,000 and 20,000 shares of common stock, respectively, vesting over four years with an exercise price equal to the closing price of our common stock on the respective date of grant. In addition, on December 10, 2008,On June 25, 2014, we granted restricted stock units as to 25,000 shares of common stock to each of Dr. Spana, Mr. Wills and Dr. Hallam, which vested on December 31, 2009.
On July 21, 2010, we granted 25,000, 20,000 and 20,000175,000 restricted stock units to Dr. Spana and 150,000 restricted stock units to Mr. Wills, and Dr. Hallam, respectively, which will vest as to 50% on September 15, 2010each anniversary of the grant date. We also granted 175,000 stock options to Dr. Spana and 150,000 stock options to Mr. Wills, which vest as to 25% on each anniversary of the remaininggrant date.

The executive’s entitlement to severance, payment of health benefits and accelerated vesting of options is contingent on the executive executing a general release of claims against us.

He may also elect to receive medical and dental benefits pursuant to COBRA for up to eighteentwo years (Dr. Spana) or 18 months (Mr. Wills), but must remit the cost of coverage to us. Under the terms of our outstanding options and restricted stock units, all unvested options and restricted stock units would terminate immediately, and vested options would be exercisable for three months after termi nation.

We would also reimburse the executive for up to $25,000 in fees and expenses during the six months following termination, for locating employment. We would also reimburse the executive for any excise tax he might incur on “excess parachute payments” ; (as defined in Section 280G(b) of the Internal Revenue Code). All unvested options would immediately vest and be exercisable for two years after the termination date or, if earlier, the expiration of the option term.

Optional conversion.   Each share of Series A is convertible at any time, at the option of the holder, into the number of shares of common stock equal to $100 divided by the conversion price, as defined in the Series A certificate of designations. The current conversion price is $18.60,$8.89, so each share of Series A is currently convertible into approximately 511.25 shares of common stock.

Mandatory conversion.We may, at our option, cause the conversion of the Series A, in whole or in part, on a pro rata basis, into common stock, if the closing bid price of the common stock has exceeded 200% of the conversion price for at least 20 trading days in any 30 consecutive trading day period, ending three days prior to the date of mandatory conversion.

Price protection provisions.The conversion price decreases if we sell common stock (or equivalents) for a price per share less than the conversion price or less than the market price of the common stock. The conversion price is also subject to adjustment upon the occurrence of a merger, reorganization, consolidation, reclassification, stock dividend or stock split which results in an increase or decrease in the number of shares of common stock outstanding.

This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code. U.S. Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly with retroactive effect, which may result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service, or IRS, with respect to the statements made and the conclusions reached in the following summary. There can be no assurance that the IRS will agree with such statements and conclusions or that any contrary position taken by the IRS would not be sustained by a court.

This summary also does not address the tax considerations arising under the laws of any foreign, state or local jurisdiction or any alternative minimum tax considerations. In addition, this discussion does not address tax considerations applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

an individual U.S. citizen or resident (as determined for U.S. federal income tax purposes);
a corporation (or other entity that is classified as a corporation for U.S. federal income tax purposes) organized under the closinglaws of the offering, weU.S. or any of its political subdivisions;
an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
a trust if (i) a court within the U.S. is able to exercise primary jurisdiction over the administration of the trust and one or more United States persons (as defined for U.S. federal income tax purposes) have the authority to control all substantial decisions of the trust or (ii) the trust has a valid election in effect under current U.S. Treasury Regulations to be treated as a United States person.

Distributions that are treated as dividends generally will pay the placement agentbe subject to United States federal withholding tax at a cash transaction fee equal to [  *  ] percent ([  *  ]%)rate of 30% of the gross proceedsamount of the dividends, or such lower rate specified by an applicable income tax treaty. To receive the benefit of a reduced treaty rate, a non-U.S. holder must furnish to us or our paying agent a valid IRS Form W-8BEN (for individuals) or IRS Form W-8BEN-E (for entities) (or applicable successor form) certifying such non-U.S. holder’s qualification for the reduced rate. This certification must be provided to us or our paying agent prior to the payment of dividends and must be updated periodically. Non-U.S. holders that do not timely provide us or our paying agent with the required certification, but that qualify for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If a non-U.S. holder holds shares of our common stock in connection with the conduct of a trade or business in the United States, and dividends paid on the shares of our common stock are effectively connected with such non-U.S. holder’s United States trade or business (and if required by an applicable income tax treaty, attributable to a permanent establishment maintained by the non-U.S. holder in the United States), the non-U.S. holder will be exempt from United States federal withholding tax. To claim the exemption, the non-U.S. holder must generally furnish to us or our paying agent a properly executed IRS Form W-8ECI (or applicable successor form).

Any dividends paid on shares of our common stock that are effectively connected with a non-U.S. holder’s United States trade or business (and if required by an applicable income tax treaty, attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be subject to United States federal income tax on a net income basis at the regular graduated United States federal income tax rates in much the same manner as if such non-U.S. holder were a resident of the United States. A non-U.S. holder that is a foreign corporation also may be subject to an additional branch profits tax equal to 30% (or such lower rate specified by an applicable income tax treaty) of its effectively connected earnings and profits for the taxable year, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Distributions in excess of our current and accumulated earnings and profits, as determined under United States federal income tax principles, will constitute a return of capital and will first be applied against and reduce a non-U.S. holder’s tax basis in the shares of our common stock, but not below zero.

With respect to the third bullet point above, we believe we will also paynot be a USRPHC for United States federal income tax purposes. Because the placement agentdetermination of whether we are a non-accountable expense allowanceUSRPHC depends on the fair market value of [  *  ]our United States real property interests relative to the fair market value of our other trade or business assets and our foreign real property interests, it is possible we could become a USRPHC in the future. As a USRPHC, if a class of our stock is regularly traded on an established securities market, such stock will be treated as a USRPI only with respect to a non-U.S. holder that actually or constructively holds more than five percent ([  *  ]%)of such class of stock at any time during the shorter of the gross proceeds to us fromfive-year period preceding the date of disposition or the holder’s holding period for such stock. We anticipate that our common stock will be regularly traded on an established securities market following this offering. However, no assurance can be given in this regard and no assurance can be given that our common stock will remain regularly traded in the future. Non-U.S. holders should consult their tax advisors concerning the consequences of disposing of shares of our common stock.

If gain on the sale of units in the offering.

In addition, we agreed to grant a [  *  ]-year (from the closing of the offering) compensation warrant to the placement agent to purchase a numberor other taxable disposition of shares of our common stock equalwere subject to [  *  ] percent ([  *  ]%)taxation under FIRPTA as a sale of a USRPI, the numbernon-U.S. holder would generally be subject to regular United States federal income tax with respect to such gain in the same manner as a taxable U.S. holder. In addition, if the sale or other taxable disposition of shares of our common stock containedis subject to tax under FIRPTA, the purchaser of the stock would be required to withhold and remit to the IRS 10% of the purchase price unless an exception applies.

A non-U.S. holder will be required to file a United States federal income tax return for any taxable year in which it realizes a gain from the disposition of our common stock that is subject to United States federal income tax.

Backup Withholding Tax and Information Reporting

We must report annually to each non-U.S. holder of shares of our common stock and to the IRS the amount of payments on the shares of our common stock paid to such non-U.S. holder and the amount of any tax withheld with respect to those payments. These information reporting requirements apply even if no withholding was required because the payments were effectively connected with the non-U.S. holder’s conduct of a United States trade or business, or withholding was reduced or eliminated by an applicable income tax treaty. This information also may be made available under a specific treaty or agreement with the tax authorities in the country in which the non-U.S. holder resides or is established. Backup withholding, however, generally will not apply to distribution payments to a non-U.S. holder of shares of our common stock provided the non-U.S. holder furnishes to us or our paying agent the required certification as to its


TABLE OF CONTENTS

non-U.S. status, such as by providing a valid IRS Form W-8BEN, IRS Form W-8BEN-E, or IRS Form W-8ECI (or other applicable successor form), or certain other requirements are met. Notwithstanding the foregoing, backup withholding may apply if either we or our paying agent has actual knowledge, or reason to know, that the holder is a U.S. person that is not an exempt recipient.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax Relating to Foreign Accounts

Withholding taxes may apply to certain types of payments made to foreign financial institutions (as specially defined in the IRC) and certain other non-United States entities. Specifically, and subject to any intergovernmental agreement that the U.S. has entered, or may enter, into with the country that a non-U.S. holder is a resident of, a 30% withholding tax may be imposed on dividends on, and gross proceeds from the sale or other disposition of, shares of our common stock paid to a foreign financial institution or to a non-financial foreign entity, unless (1) the foreign financial institution undertakes certain diligence and reporting, (2) the non-financial foreign entity either certifies it does not have any substantial United States owners or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to non-compliant foreign financial institutions and certain other account holders. Under certain circumstances, a payee may not be eligible for a refund or credit of such withholding taxes. The U.S. Department of the Treasury has issued administrative guidance providing that these withholding provisions will generally only apply to payments of dividends made on or after July 1, 2014, and to payments of gross proceeds from a sale or other disposition of stock on or after January 1, 2017.

The preceding discussion of certain foreign income tax consequences is for general information only and is not tax advice. Accordingly, each investor should consult its own tax advisor as to the particular tax consequences to it of purchasing, holding and disposing of shares of our common stock, including the applicability and effect of any foreign tax laws, and of any pending or subsequent changes in applicable laws.

Specifically, the underwriters may limitover-allot or otherwise create a short position in the timing of purchases and sales ofcommon stock for their own account by selling more shares of common stock and warrantsthan we have sold to the underwriters. Short sales involve the sale by the underwriters of a greater number of shares than the underwriters are required to purchase in the offering. The underwriters may close out any short position by either exercising their option to purchase additional shares or purchasing shares in the open market.

In addition, the underwriters may stabilize or maintain the price of the common stock by bidding for or purchasing shares of common stock byin the placem ent agent.

The placement agent agreement provides that we will indemnify the placement agent against specified liabilities, including liabilities under the Securities Act of 1933. We have been advised that, in the opinion of the Securities and Exchange Commission, indemnification for liabilities under the Securities Act of 1933 is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.

TABLE OF CONTENTS

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders


Palatin Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of Palatin Technologies, Inc. and subsidiary (the Company) as of June 30, 20102014 and 2009,2013, and the related consolidated statements of operations, cash flows, and stockholders’ equity, and comprehensive losscash flows for each of the years in the three-year period ended June 30, 2010.2014. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Palatin Technologies, Inc. and subsidiary as of June 30, 20102014 and 2009,2013, and the results of their operations and their cash flows for each of the years in the three-year period ended June 30, 2010,2014, in conformity with U.S. generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. As discussed in note 1 to the consolidated financial statements, the Company has incurred recurring net losses and negative cash flows from operations and will require substantial additional financing to continue to fund its planned development activities. These conditions raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Notes to Consolidated Financial Statements

(1) ORGANIZATION:

Nature of Business — Palatin Technologies, Inc. (Palatin or the Company) is a biopharmaceutical company dedicated todeveloping targeted, receptor-specific peptide therapeutics for the developmenttreatment of peptide, peptide mimeticdiseases with significant unmet medical need and small molecule agonist compounds with a focuscommercial potential. Palatin’s programs are based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. Palatin has a diverse pipeline of active development programs targeting melanocortin and natriuretic receptors. The melanocortin system is involved in a large and diverse number of physiologic functions, and therapeutic agents modulating this system may have the potential to treat a variety of conditions and diseases, including sexual dysfunction, obesity and related disorders, cachexia (wasting syndrome) and inflammation-related diseases. The natriuretic peptide receptor system has numerous cardiovascular funct ions,functions, and therapeutic agents modulating this system may be useful in treatment of acute asthma, heart failure, hypertension and other cardiovascular diseases.

The Company’s activeprimary product in development is bremelanotide for the treatment of female sexual dysfunction (FSD). The Company also has drug candidates or development programs consist of bremelanotide for treatment of sexualcardiovascular diseases, pulmonary diseases, obesity, erectile dysfunction, other peptide melanocortin receptor agonists for treatment of sexual dysfunction,inflammatory diseases and PL-3994, an agonist peptide mimetic which binds to natriuretic peptide receptor A, for treatment of acute asthma and heart failure.dermatologic diseases. The Company has a license, co-development and commercialization agreement with Gedeon Richter Plc. (Gedeon Richter) to commercialize bremelanotide for FSD in Europe and selected countries, and an exclusive global research collaboration and license agreement with AstraZeneca AB (AstraZeneca) to commercialize compounds that target melanocortin receptors for the treatment of obesity, diabetes and related metabolic syndrome.

Key elements of the Company’s business strategy include using its technology and expertise to develop and commercialize therapeutic products; entering into alliances and partnerships with pharmaceutical companies to facilitate the development, manufacture, marketing, sale and distribution of product candidates that the Company is developing; and partially funding its product candidate development programs with the cash flow generated from the Company’s AstraZeneca collaboration agreement and any future agreements with other companies.

Reverse Stock Split – Effective on September 27, 2010, the Company implemented a one-for-ten reverse stock split of its common stock, which reduced the number of shares of its common stock issued and outstanding from approximately 118,200,000 to approximately 11,800,000. All share and per share amounts in these consolidated financial statements, including shares of common stock issuable upon exercise, vesting or conversion of all outstanding options, warrants and convertible preferred stock, are presented on a post-reverse-split basis.
third parties.

Business Risk and Liquidity — The Company has incurred negative cash flows from operations since its inception, and has expended, and expects to continue to expend in the future, substantial funds to complete its planned product development efforts. As shown in the accompanying consolidated financial statements, the Company hashad an accumulated deficit as of June 30, 20102014 of $274.0 million and incurred a net loss for fiscal 2010.2014 of $13.9 million. The Company anticipates incurring additional losses in the future as a result of spending on its development programs. To achieve profitability, the Company, alone or with others, must successfully develop and commercialize its technologies and proposed products, conduct successful preclinical studies and clinical trials, obtain required regulatory approvals and successfully manufacture and market such technologies and proposed products. The time required to reach profitability is highly uncertain, and there can be no assurance that the Company will be able to achieve profitability on a sustained basis, if at all.

As of June 30, 2010,2014, the Company’s cash and cash equivalents were $5.4$12.2 million. In September 2014 the Company received $8.8 million pursuant to its license, co-development and its available-for-sale investments were $3.5 million.commercialization agreement with Gedeon Richter on bremelanotide for FSD in Europe and selected countries.

have adequate funds, or commitments for adequate funds, to complete Phase 3 clinical trials. The Company intends to seek additional capital to support the Phase 3 program through collaborative arrangements on bremelanotide, in addition to the Company’s agreement with Gedeon Richter, public or private equity or debt financings, collaborative arrangements on our product candidates, or other sources. However, sufficient

Management believes that the Company’s existing capital resources, including $8.8 million paid by Gedeon Richter pursuant to the agreement on bremelanotide for FSD, will be adequate to fund its planned operations through the quarter ending September 30, 2015, not including initiation of our pivotal Phase 3 clinical trials for bremelanotide for FSD or other planned clinical trials. We will need additional funding to support projected operations, includingcomplete required clinical trials with eitherof bremelanotide or PL-3994, or both, may not be available on acceptable terms or at all. These matters raise substantial doubt over the Company’s ability to continue as a going concern.

If the Company is unable to raise sufficient additional funds to advance at least one of itsfor FSD and our other product candidates management will implement plans for the orderly wind down of its business operations, including curtailing operations significantly and, further decreasing staffing levels, and will seekassuming those clinical trials are successful, as to license, sell or otherwise dispose of the Company’s product candidates, technologies and contractual rights, including rights under the research collaboration and license agreement with AstraZeneca, on the best possible terms available.
The nature and timing of the Company’s development activities are highly dependent on its financing activities. Therewhich there can be no assurance, thatcomplete submission of required regulatory applications to the Company will be able to obtain financing when required, or that financing efforts will be successful. Additionally, the Company may be required to seek collaboratorsFDA for itsany of our product candidates at an earlier stage than otherwise would be desirable and on terms that are less favorable than might otherwise be available, and relinquish, license or otherwise dispose of rights on unfavorable terms to technologies and product candidates that the Company would otherwise seek to develop or commercialize itself.

Concentrations — Concentrations in the Company’s assets and operations subject it to certain related risks. Financial instruments that subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents, available-for-sale investments and accounts receivable.equivalents. The Company’s cash and cash equivalents are primarily invested in one money market fund sponsored by a large financial institution. Revenues from collaboration partners as a percentage of totalIn the two-year period ended June 30, 2013, all license and contract revenues were as follows:

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation — The consolidated financial statements include the accounts of Palatin and its wholly-owned inactive subsidiary. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates — The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents — Cash and cash equivalents include cash on hand, cash in banks and all highly liquid investments with a purchased maturity of less than three months. Cash equivalents consist of $4,111,051$9,495,656 and $3,250,191$16,284,184 in a money market fund at June 30, 20102014 and 2009,2013, respectively. Restricted cash secures letters of credit for security deposits on leases.

Investments — The Company classifiesdetermines the appropriate classification of its investments in debt and equity securities at the time of purchase and reevaluates such determinations at each balance sheet date. Debt securities are classified as available-for-sale investmentsheld-to-maturity when the Company has the intent and all such investmentsability to hold the securities to maturity. Debt securities for which the Company does not have the intent or ability to hold to maturity are classified as available-for-sale. Held-to-maturity securities are recorded as either short-term or long-term on the balance sheet, based on the contractual maturity date and are stated at amortized cost. Marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value, based onwith unrealized gains and losses recognized in earnings. Debt and marketable equity securities not classified as held-to-maturity or as trading are classified as available-for-sale and are carried at fair market value, with the unrealized gains and losses, net of tax, included in the determination of comprehensive loss.

The fair value of substantially all securities is determined by quoted market prices. Unrealized holding gains and lossesThe estimated fair value of securities for which there are generally excluded from earnings andno quoted market prices is based on similar types of securities that are reported in accumulated other comprehensive income/loss until realized. Interest and dividends on securities classified as available-for-sale are included in investment income. Gains and losses are recordedtraded in the statement of operations when realized or when unrealized holding losses are determined to be other than temporary, on a specific-identification basis.market.

Management believes that the carrying values of these assets and liabilities are representative of their respective fair values based on quoted market prices for investments and the short-term nature of the other instruments.

Property and Equipment — Property and equipment consists of office and laboratory equipment, office furniture and leasehold improvements and includes assets acquired under capital leases. Property and equipment are recorded at cost. Depreciation is recognized using the straight-line method over the estimated useful lives of the related assets, generally five years for laboratory and computer equipment, seven years for office furniture and equipment and the lesser of the term of the lease or the useful life for leasehold improvements. Amortization of assets acquired under capital leases is included in depreciation expense. Maintenance and repairs are expensed as incurred while expenditures that extend the useful life of an asset are capitalized.

Impairment of Long-Lived Assets — The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine recoverability of a long-lived asset, management evaluates whether the estimated future undiscounted net cash flows from the asset are less than its carrying amount. If impairment is indicated, the long-lived asset would be written down to its fair value. Fair value is determined by an evaluation of available price information at which assets could be bought or sold, including quoted market prices, if available, or the present value of the estimated future cash flows based on reasonable and supportable assu mptions.

assumptions.

Deferred Rent – — The Company’s operating leases provide for rent increases over the terms of the leases. Deferred rent consists of the difference between periodic rent payments and the amount recognized as rent expense on a straight-line basis, as well as tenant allowances for leasehold improvements. Rent expenses are being recognized ratably over the terms of the leases.

Revenue Recognition — Revenue from corporate collaborations and licensing agreements consists of up-front fees, research and development funding, and milestone payments. Non-refundable up-front fees are deferred and amortized to revenue over the related performance period. The Company estimates the performance period as the period in which it performs certain development activities under the applicable agreement. Reimbursements for research and development activities are recorded in the period that the Company performs the related activities under the terms of the applicable agreements. Revenue resulting from the achievement of milestone events stipulated in the applicable agreements is recognized when the milestone is achieved, provided that such milestone is substantive in nature.

Research and Development Costs — The costs of research and development activities are charged to expense as incurred, including the cost of equipment for which there is no alternative future use.

Accrued Expenses — Third parties perform a significant portion of our development activities. We review the activities performed under significant contracts each quarter and accrue expenses and the amount of any reimbursement to be received from our collaborators based upon the estimated amount of work completed. Estimating the value or stage of completion of certain services requires judgment based on available information. If we do not identify services performed for us but not billed by the service-provider, or if we underestimate or overestimate the value of services performed as of a given date, reported expenses will be understated or overstated.

Stock-Based Compensation — The Company charges to expense the fair value of stock options and other equity awards granted. The Company determines the fair value of stock options utilizing the Black-Scholes option pricing model. Compensation costs for share-based awards with pro-rata vesting are allocated to periods on a straight-line basisbasis.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:  – (continued)

Income Taxes — The Company and its subsidiary file consolidated federal and separate-company state income tax returns. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences or operating loss and tax credit carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Company has recorded a valuation allowance against its deferred tax assets based on the history of losses incurred.

During the years ended June 30, 2010, 20092014, 2013 and 2008,2012, the Company sold New Jersey state net operating loss carryforwards, which resulted in the recognition of $998,408, $1,741,476$1,846,646, $1,753,208, and $1,291,444,$1,068,233, respectively, in tax benefits.

Net Loss per Common Share — Basic and diluted earnings per common share (EPS) are calculated in accordance with the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 260, “Earnings per Share.Share,In June 2008, the FASB issuedwhich includes guidance stating that non-vested share-based payment awards that include non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are considered participating securities, and the two-class method of computing EPS is required for

basic and diluted net loss per common share. The Company’s outstandingSeries A 2012 warrants to purchase up to 31,988,151 shares of common stock were exercisable starting at July 3, 2012 and, therefore, are included in the weighted average number of common shares outstanding used in computing basic and diluted net loss per common share starting on July 3, 2012.

The Series A Convertible PreferredB 2012 warrants to purchase up to 35,488,380 shares of common stock contain rights that entitle the holder to a special dividend or distribution of $100were considered contingently issuable shares and were not included in computing basic net loss per common share beforeuntil the Company can pay dividends or make distributionsreceived stockholder approval for the increase in authorized underlying common stock on September 27, 2012 (see note 9). For diluted EPS, contingently issuable shares are to the common stockholders. The outstanding share-based compensation awards do not include non-forfeitable rights to dividends. Accordingly, only the outstanding Series A Convertible Preferred stock is considered a participating security and must be included in the computation of EPS. The adoptioncalculation as of the provisionsbeginning of ASC Topic 260 relating to the two-class methodperiod in which the conditions were satisfied, unless the effect would be anti-dilutive.

As of June 30, 2010, 20092014, 2013 and 2008,2012, there were 29,358,926, 29,136,527, and 27,179,180 common shares issuable upon conversion of Series A Convertible Preferred Stock, the exercise of outstanding options and warrants (excluding the warrants issued in connection with the July 3, 2013 private placement offering), and the vesting of restricted stock units, amounted to an aggregate of 2,569,695, 1,407,660 and 1,394,159, respectively.

Recently Issued Accounting Pronouncements – In June 2009, the FASB issued ASC 105-10 (formerly Statement of Financial Accounting Standards 168), “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles,” which was effective for the Company beginning July 1, 2009. The FASB Accounting Standards Codification (the Codification) officially became the single source of authoritative nongovernmental generally accepted accounting principles (GAAP), superseding existing FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force and related accounting literature. After that date, only one level of authoritative GAAP exists. All other accounting literatur e is considered non-authoritative. The Codification reorganizes the thousands of GAAP pronouncements into roughly 90 accounting topics and displays them using a consistent structure. Also included in the Codification is relevant SEC guidance organized using the same topical structure in separate sections within the Codification. The Company adopted this statement and has updated its existing GAAP references to the new codification.
In September 2009, the FASB issued Accounting Standards Update (ASU) 2009-13, Revenue Recognition (Topic 605), “Multiple-Deliverable Revenue Arrangements (ASU 2009-13)”, which requires companies to allocate revenue in arrangements involving multiple deliverables based on the estimated selling price of each deliverable when such deliverables are not sold separately either by the company or other vendors. ASU 2009-13 eliminates the requirement that all undelivered elements must have objective and reliable evidence of fair value before a company can recognize the portion of the overall arrangement fee that is attributable to items that already These share amounts have been delivered. As a result,excluded from the new guidance may allow some companies to recognize revenue on transactions that involve multiple deliv erables earlier than under current requirements. ASU 2009-13 is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted atcalculation of net loss per share as the beginning of a company’s fiscal year. The Company adopted ASU 2009-13 on July 1, 2010 and does not expect ASU 2009-13 to have a material impact on its consolidated financial statements.
would be anti-dilutive.

(3) NEW AND RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820), “Improving Disclosures about Fair Value Measurements (ASU 2010-06)”, which amends the existing fair value measurement and disclosure guidance currently included in ASC Topic 820, “Fair Value Measurements and Disclosures”, to require additional disclosures regarding fair value measurements. Specifically, ASU 2010-06 requires companies to disclose the amounts of significant transfers between Level 1 and Level 2 of the fair value hierarchy and the reasons for these transfers, the reasons for any transfer in or out of Level 3 and information in the reconciliation of recurring Level 3 measurements about purchases, sales, issuances and settlements on a gross basis. In additio n, ASU 2010-06 also clarifies the requirements for companies to disclose information about both the valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except for additional disclosures related to Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010. The adoption of ASU 2010-06 did not impact the Company’s consolidated financial statements or results of operations.

In April 2010,May 2014, the FASB issued ASU No. 2010-17, Revenue Recognition – Milestone Method (ASU 2010-17). ASU 2010-17 provides guidance on applying the milestone method to milestone payments for achieving specified performance measures when those payments are related to uncertain future events. Under ASU 2010-17, entities can make2014-09, “Revenue from Contracts with Customers,” which requires an accounting policy electionentity to recognize arrangement consideration receivedthe amount of revenue to which it expects to be entitled for achieving specified performance measures during the periodtransfer of promised goods or services to customers.

The warrants also provide that in the event of a Company Controlled Fundamental Transaction (as defined in the warrants), the Company may, at the election of the warrant holder, be required to redeem all or a portion of the warrants at an amount tied to the greater of the then market price of the Company’s common stock or the amount per share paid to any other person.

Because there were not sufficient authorized shares to cover all the outstanding Series B 2012 warrants in the private placement offering as of closing, under ASC 815, “Derivatives and Hedging,” the portion of the warrants above the then authorized level of common stock was required to be classified as a liability and carried at fair value on the Company’s balance sheet. The fair value, including the initial fair value liability of $16,960,963, was calculated by multiplying the number of shares underlying the Series B 2012 warrants above the then authorized level of the Company’s common stock by the closing price of its common stock less the exercise price of $0.01 per share. NetThe warrants were liability classified through September 27, 2012, at which time the then fair value of the warrant liability was reclassified into stockholders’ equity upon stockholder approval of the increase in authorized common stock. The increase in fair value, as a result of the Company’s common stock increasing from $0.50 per share at date of issuance to $0.71 per share upon shareholder approval, of $7,069,165 has been recorded as a non-operating expense for the year ended June 30, 2013.

The purchase agreement for the private placement provides that the purchasers, funds under the management of QVT Financial LP, have certain rights until July 3, 2018, including rights of first refusal and participation in any subsequent equity or debt financing, provided that the funds own at least 20% of the outstanding common stock of the Company calculated as if warrants held by the funds were exercised. The purchase agreement also contains certain restrictive covenants so long as the funds continue to hold specified amounts of warrants or beneficially own specified amounts of the outstanding shares of common stock.

(10) INCOME TAXES  – (continued)

As of June 30, 2010,2014, the Company had federal and state net operating loss carryforwards of approximately $194,000,000$235 million and $83,000,000,$93 million, respectively, which expire between 20112014 and 20302034 if not utilized. As of June 30, 2010,2014, the Company had federal research and development credits of approximately $5,400,000$6,871,000 that will begin to expire in 2012,2014, if not utilized.

The Tax Reform Act of 1986 (the Act) provides for limitation on the use of net operating loss and research and development tax credit carryforwards following certain ownership changes (as defined by the Act) that could limit the Company’s ability to utilize these carryforwards. The Company may have experienced various ownership changes, as defined by the Act, as a result of past financings. Accordingly, the Company’s ability to utilize the aforementioned carryforwards may be limited. Additionally, U.S. tax laws limit the time during which these carryforwards may be applied against future taxes; therefore, the Company may not be able to take full advantage of these carryforwards for federal income tax purposes.

The Company’s net deferred tax assets are as follows:

  
 June 30, 2014 June 30, 2013
Net operating loss carryforwards $87,801,000  $83,470,000

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the application of loss limitation provisions related to ownership changes. Due to the Company’s history of losses, the deferred tax assets are fully offset by a valuation allowance as of June 30, 20102014 and 2009. The valuation allowance for the year ended June 30, 2010 decreased by $962,000 due to the tax treatment of certain deferred revenue.

(12) SUBSEQUENT EVENT

In August 2014, the Company entered into a license, co-development and commercialization agreement with Gedeon Richter on bremelanotide for FSD in Europe and selected countries. In August 2013, the Company received an initial payment of $1.0 million from Gedeon Richter as a non-refundable option fee on the license, co-development and commercialization agreement, and in September 2014, the Company received $8.8 million on execution of the definitive agreement. Under the agreement, Gedeon Richter will pay the Company a milestone payment of €2.5 million ($3.3 million) upon the initiation of the Company’s Phase 3 clinical trial program in the United States. The Company has the potential to receive up to €80 million ($105.6 million) in regulatory and sales related milestones, and will receive low double-digit royalties on net sales in the licensed territory. Under the agreement the Company will contribute, with Gedeon Richter, to the costs of co-development activities for obtaining regulatory approval in Europe. Gedeon Richter will exclusively market bremelanotide for FSD in the licensed territory, and will be responsible for all sales, marketing and commercial activities, including associated costs, in the licensed territory. The agreement remains in effect as long as Gedeon Richter is selling bremelanotide on which a royalty is owed. The agreement may be terminated by either party upon notice in the event of a material breach or insolvency. In the event Gedeon Richter terminates the agreement because the Company breached the agreement or is insolvent, Gedeon Richter’s license will becomes fully paid-up, royalty free, perpetual and irrevocable. If the Company fails to initiate its Phase 3 program by an agreed date, Gedeon Richter at its option may elect to terminate the license and receive a specified payment. In the event that the Company terminates the agreement because Gedeon Richter breached the agreement or is insolvent, upon timely request all regulatory approvals for bremelanotide in the licensed territory will be transferred to the Company or its designee.

(3)                                  To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)           That, for the purpose of determining liability under the Securities Act of 1933 in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: 
i.           Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; 
ii.           Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; 
iii.           The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and 
iv.           Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
(b)           

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the CommissionSEC such indemnification is against public policy as expressed in the Securities Act, of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being regi stered,registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes:

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement
(2)For the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.
(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)For the purpose of determining liability under the Securities Act to any purchaser in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(d)           The undersigned registrant hereby undertakes that:
(1)           

For purposes of determining any liability under the Securities Act, of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)           

For the purpose of determining any liability under the Securities Act, of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.
