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 hypoactive sexual desire disorder, or HSDD, which is a type of female sexual dysfunction, or 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 HSDD in premenopausal women. Bremelanotide, which is a melanocortin agonist, 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 response. Bremelanotide is in Phase 3 clinical trials;

●

Melanocortin receptor-4, or MC4r, compounds for treatment of obesity and diabetes. 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, HSDD, erectile dysfunction or ED, obesity and diabetes;

●

PL-3994, a 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 atrial natriuretic peptide, or 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 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.

The following chart illustrates the status of our drug development programs.

S-1

We initiated patient enrollment in Phase 3 clinical trials of bremelanotide for the treatment of HSDD in premenopausal women in the fourth quarter of calendar 2014, and completed patient enrollment in the fourth quarter of calendar 2015, with last patient out projected for the third quarter of calendar 2016 and topline results project for the third or fourth quarter of calendar 2016. We cannot assure you that the Phase 3 data will support approval of bremelanotide for HSDD or that the U.S. Food and Drug Administration, or FDA, will approve a new drug application, or NDA, for bremelanotide.

Our 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 HSDD and our other product candidates.

At March 31, 2016, we had an accumulated deficit of approximately $330.1 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 that our existing capital resources will be adequate to fund our planned operations through the quarter ending September 30, 2016. Following this offering, assuming the Phase 3 clinical trials of bremelanotide for HSDD are successful, as to which there can be no assurance, we will need additional funding to complete additional required studies and trials and for submission of required regulatory applications to the FDA for bremelanotide for HSDD. 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 HSDD 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 condition and our ability to pursue our business strategy.

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, pigmentation disorders and inflammation-related diseases.

Bremelanotide for HSDD. We are developing subcutaneously administered bremelanotide for the treatment of HSDD 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. We initiated patient enrollment in Phase 3 clinical trials in the fourth quarter of calendar 2014, and patient enrollment was completed in the fourth quarter of calendar 2015, with topline results expected in the third or fourth quarter of calendar 2016.

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 premenopausal 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 HSDD.

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 FSDSDAO (69% vs. 45%).

S-3

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, and was published in Women’s Health, 12:3425-337 (2016).

Phase 3 Clinical Trial. We reached preliminary agreement with the United States Food and Drug Administration, or FDA, on key aspects of the bremelanotide Phase 3 pivotal registration studies, including HSDD 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. The FDA also agreed that the intranasal Definitive QTc study, the carcinogenicity studies and reproductive toxicity studies we conducted were acceptable for NDA submission. There were no outstanding chemistry, controls or manufacturing issues. Based upon the discussions with the FDA, we completed and submitted protocols for the pivotal Phase 3 studies in the early fourth quarter of calendar 2014, manufactured drug product for clinical trial use, and negotiated agreements with clinical research organizations and others for Phase 3 studies.

The Phase 3 clinical trials are being conducted in premenopausal women with HSDD, either with or without arousal difficulties, and 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. HSDD is the single largest specific diagnosis in FSD. A 24-week treatment evaluation period is being conducted, 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.

The Phase 3 trials, which we are conducting in North America, utilize a single-dose autoinjector intended for commercialization. We will also conduct drug interaction and other ancillary studies. The Phase 3 program is taking approximately twenty months from initiation of patient dosing in the first trial through database lock in the second trial. Following database lock, clinical trial data will be analyzed and, assuming that we believe the data would support approval of bremelanotide for HSDD, an NDA will be submitted to FDA. We cannot assure you that the Phase 3 data will support approval of bremelanotide for HSDD or that the FDA will approve an NDA for bremelanotide.

Medical Need. FSD is a multifactorial condition that has anatomical, physiological, medical, psychological and social 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, HSDD, female sexual arousal disorder, sexual pain disorder and orgasmic disorder. HSDD, either with or without arousal difficulties, is the largest single category of FSD. To establish a diagnosis of HSDD, these syndromes must be associated with personal distress, as determined by the affected women. The 2006 PRESIDE (Prevalence of Female Sexual Problems Associated with Distress and Determinants of Treatment Seeking) study, a cross-sectional, population-based survey of 31,581 female adult respondents in the United States published in 2008 in the journal Obstetrics & Gynecology, found that approximately 22% of women reported a sexual problem and 11% were distressed by their sexual problems, with one-third of 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 HSDD market is projected to be about $1.3 billion by 2020.

S-4

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 HSDD. 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 being used in Phase 3 clinical trials and is intended for commercialization.

Partnering. In August 2014, we entered into a license agreement with Gedeon Richter to co-develop and commercialize bremelanotide for FSD in the European Union, other European countries and additional selected countries. We received €7.5 million ($9.8 million) in total upfront payments from Gedeon Richter, and a milestone payment of €2.5 million ($3.1 million) upon the initiation of our Phase 3 clinical trial program in the United States. On September 16, 2015, we entered into a termination agreement pursuant to which we and Gedeon Richter agreed to mutually and amicably terminate the license agreement. In connection with this termination, all rights and licenses to co-develop and commercialize bremelanotide for HSDD indications held by Gedeon Richter terminated and reverted back to us. Neither we nor Gedeon Richter have any future material obligations under the license agreement.

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

Prior Clinical Trials. We have completed several Phase 1 clinical studies in which various safety parameters, including blood pressure effects of subcutaneously administered bremelanotide, were studied. Based in part on these studies, our Phase 2B clinical trial assessed the magnitude and duration of blood pressure effect, and determined that subcutaneous administration of selected doses of bremelanotide for treatment of HSDD 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 efficacy in both HSDD and ED.

MC1r Peptide Agonists. We have initiated preclinical studies with MC1r peptide drug candidates for a number of indications, primarily inflammatory disease-related and autoimmune indications. The MC1r is upregulated in a number of diseases, including inflammatory bowel disease, nephritis, which is inflammation of the kidneys, and rheumatoid arthritis, and ocular indications such as uveitis and dry eye. We believe that MC1r peptides have an anti-inflammatory effect and are involved in regulation of the immune 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 preclinical toxicology testing on PL-8177 and chemistry, controls and manufacturing activities to support Phase 1 studies, and anticipate filing an IND application on PL-8177.

S-5

MC4r Peptide Agonists. We have developed a series of next generation highly selective MC4r peptides. In developing these peptides, we examined effectiveness 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. Results of these studies suggest that certain of these peptides may have significant commercial potential for treatment of conditions responsive to MC4r activation, including HSDD, FSD, ED, obesity and diabetes. We are engaged in preclinical activities with these peptides, and are evaluating potential pharmaceutical applications.

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.

Our 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 expired because AstraZeneca ceased developing a compound covered by the agreement. All rights and licenses that we granted to AstraZeneca terminated upon expiration of the agreement.

Obesity. Obesity is a multifactorial condition with numerous 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 melanocortin receptor agonists can decrease food intake and induce weight loss. With a previous partner, we completed clinical proof-of-concept studies for the MC4r mechanism in obesity, which met the primary objectives of significant decrease in food intake and weight loss.

Other Melanocortin Programs. We are continuing drug discovery efforts in the melanocortin field, primarily developing peptide compounds, including highly selective MC1r agonists and peptides specific for MC4r, including both agonists and antagonists.

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, acute asthma, other pulmonary diseases and 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 NPRC, 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. PL-3994 is in development for treatment of heart failure, acute exacerbations of asthma 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, 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, 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 function.

PL-3994, our lead product development candidate which is ready for Phase 2 safety and efficacy studies, is one of a number of natriuretic peptide receptor agonist compounds we have developed. PL-3994 is a synthetic molecule incorporating a novel and proprietary amino acid mimetic structure, and has an extended circulation half-life and metabolic stability compared to endogenous ANP. Based on the half-life and pharmacokinetics, we believe that PL-3994 is amenable to once daily chronic use subcutaneous administration.

S-6

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 could 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 hypertrophy (increase in heart size due to disease), which is an independent risk factor for cardiovascular morbidity and mortality.

According to a report from the American Heart Association published in 2014 in the journal Circulation, an estimated 5.7 million Americans suffer from heart failure, with 870,000 new cases of heart failure diagnosed each year, with disease incidence expected to increase with the aging of the American population. Heart failure has tremendous human and financial costs. The same report estimated that the 2012 total costs in the United States for heart failure were $30.7 billion, with heart failure constituting the leading cause of hospitalization in people over 65 years of age and with over 1 million hospital discharges for heart failure in 2010. Heart failure is a high mortality disease, with approximately 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 with HF-PEF, HF-REF and corin deficiency to evaluate safety profiles and symptom relief as well as pharmacokinetic (period to metabolize or excrete the drug) and pharmacodynamic (period of action or effect of the drug) endpoints. Analysis will include cardiac imaging and measurement of left ventricular ejection fraction. Contingent on adequate available funds, we intend to initiate this trial in the first half of calendar 2017. Assuming favorable results from this trial, we have planned a repeat dose Phase 2 proof-of-principle clinical trial in patients with heart failure, which 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. Contingent on adequate available funds, the proof-of-principle Phase 2 trial will be initiated following completion of the first repeat dose Phase 2 clinical trial.

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 treatment for those at-risk unresponsive patients.

S-7

According to a 2014 report from the National Center for Environmental Health, Asthma Prevalence in the United States, in 2010 there were 1.8 million emergency room visits and 439,000 hospitalizations attributed to asthma. Approximately 25.7 million Americans have asthma.

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 resistant 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 by subcutaneous injection, with biological effects seen for over eight hours post-administration.

Clinical Studies with PL-3994. Human clinical studies of PL-3994 commenced with a Phase 1 trial which concluded in 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. 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, increased diuresis and increased natriuresis were all observed for several hours after single subcutaneous doses.

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. For heart failure and refractory hypertension indications we believe that subcutaneous administration of PL-3994 may be preferable. PL-3994 is well absorbed through the 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 appropriate for self-administration by patients, similar to insulin and other self-administered drugs. For asthma indications we believe that inhalation administration of PL-3994 may be preferable to subcutaneous or 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 and refractory hypertension.

Some compound series have been derived using our proprietary and patented platform technology, called MIDAS™, or Metal Ion-induced Distinctive Array of Structures. 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 addition, MIDAS molecules are information-rich and provide data on structure-activity relationships that may be used to design small molecule, non-peptide drugs.

These risks should be considered in conjunction with any other information included or incorporated by reference herein, including in conjunction with forward-looking statements made herein. See the section of this prospectus supplement entitled “Where You Can Find More Information.” If any of the following risks actually occur, they could materially adversely affect our business, financial condition, operating results or prospects.

Risks Related to this Offering

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 80,049,536 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 executive officers will be available for sale upon expiration of a lock-up period, which we expect will expire 30 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 the 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 new investor, you will experience immediate and substantial dilution as a result of this offering.

As of March 31, 2016, we had a negative net book value (deficit) of approximately ($4.7) million, or ($0.07) per share of common stock, assuming the conversion of all then convertible preferred stock (but excluding the exercise of any outstanding warrants or options, including warrants exercisable at $0.01 per share). The public offering price of the Series A Units and Series B Units offered pursuant to this prospectus supplement is substantially higher than the net book value per share of our common stock. Therefore, you will incur immediate and substantial dilution in the pro forma net book value per share. See the section of this prospectus supplement entitled “Dilution” for a more detailed discussion of the dilution you will incur in this offering. Furthermore, we expect that we will seek to raise additional capital from time to time in the future. Such financings may involve the issuance of equity and/or securities convertible into or exercisable or exchangeable for our equity securities. We also expect to continue to utilize equity-based compensation. To the extent the warrants and options are exercised or we issue common stock, preferred stock, or securities such as warrants that are convertible into, exercisable or exchangeable for, our common stock or preferred stock in the future, you may experience further dilution.

We will have broad discretion over the use of the proceeds of this offering and may not realize a return.

Our management will have broad discretion over the use of our net proceeds from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. Our management might not apply our net proceeds in ways that ultimately increase the value of your investment and we might not be able to yield a significant return, if any, on any investment of these net proceeds. Our failure to apply these funds effectively could have a material adverse effect on our business, delay the development of our products and cause the price of our common stock to decline.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of Units in this offering will be approximately $8.5 million, after deducting the estimated underwriting discounts and commissions and estimated offering expenses of approximately $175,000 payable by us.

We intend to use the net proceeds to us from this offering primarily to complete our Phase 3 clinical trials for our primary product candidate, bremelanotide, which is used for HSDD, to complete other clinical and nonclinical studies with bremelanotide, to analyze clinical trial and preclinical data and to prepare and submit an NDA to FDA for approval of bremelanotide for FSD, and secondarily for preclinical and clinical development of our other product candidates and programs, including PL-3994 and MC1r and MC4r programs. The remainder of the net proceeds will be allocated for working capital and other general corporate purposes. Pending use of the net proceeds as described above, we intend to invest the net proceeds in short-term, interest-bearing, investment-grade securities.

The amounts actually expended for each purpose and the timing of these expenditures may vary significantly depending upon numerous factors, including the results of the Phase 3 clinical trials of bremelanotide for HSDD. Expenditures will also depend upon the availability of additional financing, whether we are able to enter into an agreement with a development and marketing partner for bremelanotide for HSDD in the United States, or PL-3994, MC1r or MC4r in the United States or elsewhere, and if so, the terms and conditions of such agreement, and other factors. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, our management will retain broad discretion as to the allocation of the net proceeds from this offering.

We expect that the proceeds from this offering will not be sufficient for us to complete Phase 3 clinical trials for bremelanotide for HSDD, complete other clinical and nonclinical studies with bremelanotide, analyze the data from Phase 3 clinical trials, and prepare and submit an NDA to FDA for bremelanotide for HSDD, or to complete necessary steps for commercial scale manufacturing and marketing of bremelanotide, or to obtain approval of any of our other product candidates by the FDA, and we will need significant additional funds in the future. It is also possible that we will not achieve the progress that we expect with respect to results of or submission of an NDA for bremelanotide for HSDD because the actual results, costs and timing of clinical development activities are difficult to predict and are subject to substantial risks and delays. See the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation” in this prospectus supplement and the documents incorporated by reference herein.

S-15

DILUTION

A purchaser of our securities in this offering 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 (deficit) as of March 31, 2016, was approximately ($4.70) million, or ($0.07) per share of outstanding common stock, based on shares of common stock outstanding as of March 31, 2016, assuming the conversion of all then convertible preferred stock (but excluding the exercise of any outstanding warrants or options, including warrants exercisable at $0.01 per share). 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.

Assuming the exercise of all of the pre-funded Series I Warrants being offered in this offering for $0.01 per share and after giving effect to the sale 11,481,481 Series A Units at the public offering price of $0.675 per Series A Unit and 2,218,045 Series B Units at the public offering price of $0.665 per Series B Unit (which equals the public offering price of a Series A unit, less the $0.01 exercise price per share of each pre-funded Series I Warrant), and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the Series H Warrants issued pursuant to this offering, our as adjusted net book value as of March 31, 2016 would have been approximately $3.8 million, or approximately $0.05 per share of outstanding common stock. This amount represents an immediate increase in net book value of $0.12 per share of our common stock to our existing stockholders and an immediate dilution of $0.625 per share of our common stock to new investors purchasing securities in this offering, as illustrated in the following table:

Public offering price per Series A Unit		$0.675
Public offering price per Series B Unit		$0.665
Exercise price per share of the pre-funded Series I Warrants		$0.010
Historical net book value per share as of March 31, 2016	$(0.07)
As adjusted increase in net book value per share attributable to new investors in this offering	$0.12
As adjusted net book value per share of our common stock after this offering		$0.050
Dilution of as adjusted net book value per share to new investors		$0.625

The foregoing table does not take into account further dilution to new investors that could occur upon the exercise of outstanding options, restricted stock units and warrants having a per share exercise price less than the per Unit offering price to the public in this offering.

The foregoing table is based on 68,040,008 shares of our common stock outstanding as of March 31, 2016 and assumes the conversion of all then convertible preferred stock and assumes the issuance of 2,218,045 shares of our common stock upon the exercise of all of the pre-funded Series I Warrants being offered in this offering and excludes:

●

5,159,140 shares issuable on the exercise of stock options, at exercise prices ranging from $0.49 to $24.90 per share;

●

3,054,442 shares issuable under restricted stock units which vest on dates between June 11, 2016 and January 11, 2020, subject to the fulfillment of service conditions; and

●

112,508,356 shares issuable on the exercise of warrants at exercise prices ranging from $0.01 to $1.00 per share.

If, at the time of exercise of a warrant, there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of, the shares of common stock issuable upon exercise of the warrant or the prospectus contained in the registration statement is not available for the issuance of the shares of common stock issuable upon exercise of the warrant, the holder may only exercise the warrant, in whole or in part, on a cashless basis.

S-17

The exercise price of the Series H Warrants is subject to adjustment in the event of a reclassification or merger, subdivision or combination of shares, stock dividends, and other distributions.

●

Stock Dividends and Splits. If the Company, at any time from and after the issuance date and while the Series H Warrant is outstanding: (i) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of common stock into a greater number of shares, the exercise price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares issuable upon exercise of the Series H Warrant will be proportionately increased, or (ii) combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of common stock into a smaller number of shares, the exercise price in effect immediately prior to such combination will be proportionately increased and the number of shares issuable upon exercise will be proportionately decreased.

●

Par Value. The Series H Warrant limits the Company’s ability to subdivide (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of common stock into a greater number of shares if it would cause the exercise price of the Series H Warrants to be less than the par value of the common stock.

●

Rights Upon Distribution of Assets. If the Company declares or makes any dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of shares of its common stock (a “Distribution”), at any time after the issuance date, then the holder will be entitled to participate in such Distribution to the same extent that the holder would have participated if the holder had held the number of shares of common stock acquirable upon complete exercise of the Series H Warrant (without regard to any limitations on exercise of the Series H Warrant) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution.

●

Purchase Rights. In addition to any adjustments described above, if at any time after the issuance date and prior to the expiration date the Company grants, issues or sells any rights, warrants or options to subscribe for or purchase shares of common stock or other stock or securities, directly or indirectly convertible into, or exercisable or exchangeable for, shares of common stock, or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of common stock (the “Purchase Rights”), then the holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the holder could have acquired if the holder had held the number of shares of common stock acquirable upon complete exercise of the Series H Warrant (without regard to any limitations on exercise of the Series H Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of common stock are to be determined for the grant, issue or sale of such Purchase Rights.

Upon each adjustment in the exercise described above, the number of shares of common stock purchasable under the Series H Warrant will be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the exercise price by a fraction, the numerator of which shall be the exercise price immediately prior to such adjustment and the denominator of which shall be the exercise price immediately thereafter.

Series I Warrants

The pre-funded Series I Warrants will have an exercise price of $0.01 per share, subject to adjustment. They will be exercisable immediately and will expire on the ten year anniversary of the issuance date. The holder will not have the right to exercise any portion of the Series I Warrant if the holder, together with its affiliates, would, subject to certain limited exceptions, beneficially own in excess of 9.99% of our common stock outstanding immediately after the exercise (subject, in certain instances, to an increase to 19.99%). The Series I Warrants include customary adjustment provisions that are substantially similar to the ones contained in the Series H Warrants. The Series I Warrants include an option for cashless exercise at the option of the holder.

UNDERWRITING

We are offering the Units described in this prospectus supplement through Canaccord Genuity Inc. as sole bookrunner of this offering and as representative of the underwriters. We have agreed to sell to the underwriters, and the underwriters have agreed to purchase from us, the number of Units listed next to their names in the following table:

Underwriters	Number of Series A Units	Number of Series B Units
Canaccord Genuity Inc.	6,314,815	1,219,925
Roth Capital Partners, LLC	5,166,666	998,120

Total	11,481,481	2,218,045

Each underwriter is committed to purchase all the Units offered by us if it purchases any Units.

Each underwriter proposes to offer the Units directly to the public at the Series A Unit public offering price and Series B Unit public offering price set forth on the cover page of this prospectus. After the offering, these figures may be changed by the underwriters.

The underwriting fee is equal to the public offering price per Unit less the amount paid by the underwriters to us per Unit. The following table shows the per Unit and total underwriting discount to be paid to the underwriters in this offering.

	Per Series A Unit	Per Series B Unit	Maximum Offering Amount
Public offering price	$0.6750	$0.6650	$9,224,999.60
Underwriting discount and commissions (1)	$0.0405	$0.0399	$553,499.98
Proceeds to us, before expenses	$0.6345	$0.6251	$8,671,499.62

We estimate that the total fees and expenses payable by us, excluding underwriting discount, will be approximately $175,000, which includes $50,000 that we have agreed to reimburse the underwriters for the fees and expenses incurred by them in connection with the offering.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make in respect of those liabilities.

We and our Chief Executive Officer and Chief Financial Officer are subject to lock–up agreements that, subject to certain exceptions, prohibit us and them from offering, pledging, selling, contracting to sell, selling any option or contracting to purchase, purchasing any option or contracting to sell, granting any option, right or warrant to purchase, or otherwise transferring or disposing of, directly or indirectly, any of our shares of common stock or any of our securities convertible into or exercisable or exchangeable for our common stock, or publicly disclosing the intention to make any offer, sale, pledge or disposition, or entering into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock or such other of our securities, whether any such transaction described above is to be settled by delivery of our common stock or such other of our securities, in cash or otherwise or make any demand for or exercise any right with respect to the registration of any shares of our common stock or any security convertible into or exercisable or exchangeable for our common stock without the prior written consent of Canaccord Genuity Inc. These restrictions will be in effect for a period of 30 days after the date of this prospectus supplement.

S-19

The lock–up agreements do not prohibit us from issuing shares upon the exercise or conversion of securities outstanding on the date of this prospectus supplement. The lock–up provisions do not prevent us from selling securities to the underwriters pursuant to the underwriting agreement, or from granting options to acquire securities under our existing stock option plans or issuing shares upon the exercise or conversion of securities outstanding on the date of this prospectus supplement.

Our common stock is listed on the NYSE MKT under the symbol “PTN.” We do not intend to list the Warrants to be sold in this offering on any securities exchange.

In order to facilitate the offering of the Units, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock. Specifically, the underwriters may sell more Units than they are obligated to purchase under the underwriting agreement, creating a short position. The underwriters must close out any short position by purchasing shares of common stock in the open market. A short position may be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchased in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of our common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of our common stock above independent market levels or prevent or slow a decline in the market price of our common stock. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

This prospectus supplement and the accompanying prospectus in electronic format may be made available on the web sites maintained by the underwriters and the underwriters may distribute prospectuses and prospectus supplements electronically.

From time to time in the ordinary course of its businesses, the underwriters and certain of their affiliates have engaged, and may in the future engage, in commercial banking or investment banking transactions with us and our affiliates for which they have received, or in the future may receive, customary fees.

PROSPECTUS SUMMARY

This summary highlights certain information appearing elsewhere in this prospectus and in the information incorporated by reference. This summary is not complete and does not contain all of the information you should consider prior to investing in our securities. After you read this summary, you should read and consider carefully the more detailed information and financial statements and related notes that we include in this prospectus or incorporate by reference, especially the section entitled “Risk Factors.” If you invest in our securities, you are assuming a high degree of risk.

Unless we have indicated otherwise or the context otherwise requires, references in the prospectus to “Palatin,” the “Company,” “we,” “us” and “our” or similar terms refer to the operations of Palatin Technologies, Inc. and its subsidiary.

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 a combination drug-device product for the delivery of bremelanotide for the treatment of female sexual dysfunction, or 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 (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 arousal response. Bremelanotide started Phase 3 clinical trials in the last quarter of calendar 2014;

●

Melanocortin receptor-4, or 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, 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 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.

The following chart shows the status of our drug development programs.

Our Strategy

Key elements of our business strategy include:

●

Using our technology and expertise to develop and commercialize products in our active drug development programs;

●

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.

Risks Related to Our Business

Our business is subject to numerous risks and uncertainties, including those incorporated by reference in the section of this prospectus entitled “Risk Factors,” which you should read carefully before deciding to invest in our securities. These risks include, among others, the following:

●

We have incurred substantial losses since our inception and we anticipate that we will continue to incur losses for the foreseeable future. We expect to incur additional losses as we continue our development of bremelanotide for FSD, PL-3994 and other product candidates and, unless and until we receive regulatory approval under applicable regulatory requirements, we cannot sell our products and will not have product revenues from them;

●

We are substantially dependent on the clinical and commercial success of our product candidates, primarily our lead product candidate, bremelanotide for FSD, for which we are have initiated Phase 3 clinical trials;

●

We may be unable to obtain regulatory approval for bremelanotide for FSD or future product candidates under applicable regulatory requirements. The denial or delay of any such approval would delay commercialization and have a material adverse effect on our potential to generate revenue, our business and our results of operations;

●

Even if bremelanotide for FSD or our other product candidates receive regulatory approval, they may fail to achieve the level of market acceptance needed for us to have commercial success. Our product candidates, if approved, will face significant competition and our failure to effectively compete may prevent us from achieving significant market penetration and expansion;

●

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;

●

If 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.

The Offering

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (SEC) utilizing a “shelf” registration process. Under this process, we may sell any combination of the securities described in this prospectus in one or more offerings up to a total dollar amount of $100.0 million. This prospectus provides you with a general description of the securities we may offer. Each time we offer to sell securities under this prospectus, we will provide a prospectus supplement containing specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. To the extent that any information we provide in a prospectus supplement is inconsistent with information in this prospectus, the information in the prospectus supplement will modify or supersede this prospectus. You should read both this prospectus and any prospectus supplement together with the additional information described under the headings “Incorporation of Information by Reference” and “Where You Can Find More Information.”

You should rely only on the information contained or incorporated by reference in this prospectus and in any prospectus supplement. We have not authorized anyone to provide you with different information. We are not offering the securities in any jurisdiction where the offering is prohibited. You should not assume that the information in this prospectus, any prospectus supplement or any document incorporated by reference is truthful or complete at any date other than the date mentioned on the cover page of those documents.

RISK FACTORS

Investing in our securities involves risks which you should consider carefully. We have set forth below risk factors related specifically to this offering. For risks related to our business operations, see “Risk Factors” in our quarterly report on Form 10-Q for the quarter ended March 31, 2015, and all subsequent reports that we file with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have incorporated those reports by reference into this prospectus. See “Incorporation of Information by Reference” and “Where You Can Find More Information” below.

Risks Related To The Offering

We expect to sell additional equity securities, which will cause dilution.

We expect to sell more equity securities in the future to obtain operating funds. We may sell these securities at a discount to the market price. Any future sales of equity will dilute the holdings of existing stockholders, possibly reducing the value of their investment.

Investors in this offering may suffer immediate dilution.

As of March 31, 2015, and after giving effect to the net proceeds of our 2015 private offering and our 2015 venture loan, we had a pro forma net book value of $44.1 million which yields a net book value of $1.05 per share of common stock, assuming the conversion of all then convertible preferred stock and no exercise of any warrants or options. If you pay more than the net tangible book value per share for stock in this offering, you will suffer immediate dilution.

As of August 17, 2015 there were 132,241,213 shares of common stock underlying outstanding convertible preferred stock, options, restricted stock units and warrants. Stockholders may experience dilution from the conversion of preferred stock, exercise of outstanding options and warrants and vesting of restricted stock units.

As of August 17, 2015, holders of our outstanding dilutive securities had the right to acquire the following amounts of underlying common stock:

●

70,622 shares issuable on the conversion of immediately convertible Series A Convertible preferred stock, subject to adjustment, for no further consideration;

●

5,080,956 shares issuable on the exercise of stock options, at exercise prices ranging from $0.60 to $24.90 per share;

●

1,028,017 shares issuable under restricted stock units which vest on dates between June 11, 2016 and June 11, 2019, subject to the fulfillment of service conditions; and

●

126,061,618 shares issuable on the exercise of warrants at exercise prices ranging from $0.01 to $1.00 per share, which includes warrants issued in our 2015 private offering for 21,917,808 shares issuable at an exercise price of $0.01 per share and for 2,191,781 shares issuable at an exercise price of $0.91 per share, and warrants issued in connection with our 2015 venture loan for 549,450 shares issuable at an exercise price of $0.91 per share.

If the holders convert, exercise or receive these 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, which could result in significant downward pressure on our stock price and could also negatively impact our ability to raise equity capital.

We will have broad discretion over the use of the proceeds of this offering and you may not realize a return.

We will have considerable discretion in the application of the net proceeds of this offering. We have not determined the amount of net proceeds that we will apply to various corporate purposes, including potential acquisitions. We may use the net proceeds for purposes that do not yield a significant return, if any, for our stockholders.

As of August 17, 2015, there were 57,128,433 shares of our common stock outstanding, and a maximum of 132,241,213 shares of common stock were issuable on conversion of outstanding convertible preferred stock, exercise of outstanding options and warrants, and vesting of performance-based stock grants.

Holders of our common stock are entitled to one vote per share for the election of directors and on all other matters that require stockholder approval. Holders of shares of common stock do not have any cumulative voting rights. Subject to any preferential rights of any outstanding preferred stock, in the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in the assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred stock. See “Preferred Stock” and “Series A Convertible Preferred Stock,” below. Our common stock does not carry any redemption rights or any preemptive or preferential rights enabling a holder to subscribe for, or receive shares of, any class of our common stock or any other securities convertible into shares of any class of our common stock. Holders of our common stock have the right to participate ratably in dividend distributions. Our outstanding Series A Preferred Stock, consisting of 4,697 shares on July 31, 2015, provides that we may not pay a dividend or make any distribution to holders of any class of stock unless we first pay a special dividend or distribution of $100 per share to the holders of the Series A Preferred Stock.

Market Information

Our common stock is listed on the NYSE MKT under the symbol “PTN.” On August 17, 2015, the closing price of the common stock was $1.04 per share. We do not have any other class of securities listed for trading.

Transfer Agent and Registrar

The transfer agent for our common stock and our Series A and Series B warrants is American Stock Transfer & Trust Company, located at 6201 15th Avenue, Brooklyn, New York 11219. Their telephone number is (800) 937-5449.

Preferred Stock

We have the authority to issue 10,000,000 shares of preferred stock. As of August 17, 2015, 264,000 shares of our preferred stock were designated as a single class, Series A Convertible Preferred Stock, of which 4,697 shares were outstanding (see “Series A Convertible Preferred Stock” below). The description of preferred stock provisions set forth below is not complete and is subject to and qualified in its entirety by reference to our amended and restated certificate of incorporation and the certificate of designations relating to the Series A Convertible Preferred Stock.

The board of directors has the right, without the consent of holders of common stock, to designate and issue one or more series of preferred stock, which may be convertible into common stock at a ratio determined by the board. A series of preferred stock may bear rights superior to common stock as to voting, dividends, redemption, distributions in liquidation, dissolution, or winding up, and other relative rights and preferences. The board may set the following terms of any series preferred stock (which will be specified in the applicable prospectus supplement):

●

the number of shares constituting the series and the distinctive designation of the series;

●

dividend rates, whether dividends are cumulative, and, if so, from what date and the relative rights of priority of payment of dividends;

●

voting rights and the terms of the voting rights;

●

conversion privileges and the terms and conditions of conversion, including provision for adjustment of the conversion rate;

●

redemption rights and the terms and conditions of redemption, including the date or dates upon or after which shares may be redeemable, and the amount per share payable in case of redemption, which may vary under different conditions and at different redemption dates;

●

sinking fund provisions for the redemption or purchase of shares;

●

rights in the event of voluntary or involuntary liquidation, dissolution or winding up of the corporation, and the relative rights of priority of payment; and

●

any other relative powers, preferences, rights, privileges, qualifications, limitations and restrictions of the series.

Dividends on outstanding shares of preferred stock will be paid or declared and set apart for payment before any dividends may be paid or declared and set apart for payment on the common stock with respect to the same dividend period.

If upon any voluntary or involuntary liquidation, dissolution or winding up of the corporation, the assets available for distribution to holders of preferred stock are insufficient to pay the full preferential amount to which the holders are entitled, then the available assets will be distributed ratably among the shares of all series of preferred stock in accordance with the respective preferential amounts (including unpaid cumulative dividends, if any) payable with respect to each series.

Holders of preferred stock will not be entitled to preemptive rights to purchase or subscribe for any shares of any class of capital stock of the corporation. The preferred stock will, when issued, be fully paid and non-assessable. The rights of the holders of preferred stock will be subordinate to those of our general creditors.

Series A Convertible Preferred Stock

The board of directors established a series of 264,000 shares of preferred stock, designated Series A Convertible Preferred Stock, par value $0.01 per share (the “Series A”). We issued 137,780 shares of Series A in 1997, of which 4,697 shares remain outstanding as of August 17, 2015, the rest having been converted into common stock. The Series A has the following rights and preferences.

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 $6.65, so each share of Series A is currently convertible into approximately 15 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.

Dividend and distribution preference. We may not pay a dividend or make any distribution to holders of any other capital stock unless and until we first pay a special dividend or distribution of $100 per share to the holders of Series A.

Liquidation preference. 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 Palatin is not the surviving entity or in 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 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 any.

Voting rights. Each holder of Series A has the number of votes equal to the number of shares of common stock issuable upon conversion of the holder’s Series A at the record date for determination of the stockholders entitled to vote or, if no record date is established, at the date a vote is taken. Except as provided above or as required by applicable law, the holders of the Series A are entitled to vote together with the holders of the common stock and not as a separate class.

●

in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or

●

Exercise of Warrants. Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M. New York time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and/or in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for the warrants (cashless exercise).

We will describe in the applicable prospectus supplement exercise procedures for warrants in a book-entry form, if any.

Enforceability of Rights by Holders of Warrants. Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW

AND OUR CHARTER DOCUMENTS

Amended and Restated Certificate of Incorporation

Our amended and restated certificate of incorporation authorizes the issuance of up to 10,000,000 shares of preferred stock, par value $.01 per share, of which 264,000 shares are currently designated as Series A Convertible Preferred Stock. The board of directors has the authority, without further approval of the stockholders, to issue and determine the rights and preferences of other series of preferred stock, except as limited by the certificate of designation for the Series A. The board could issue one or more series of preferred stock with voting, conversion, dividend, liquidation, or other rights which would adversely affect the voting power and ownership interest of holders of common stock. This authority may have the effect of deterring hostile takeovers, delaying or preventing a change in control, and discouraging bids for our common stock at a premium over the market price.

Section 203 of the Delaware General Corporation Law

We are subject to Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder, unless:

●

prior to such time, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder;

●

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (a) by persons who are directors and also officers and (b) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

●

at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two thirds of the outstanding voting stock which is not owned by the interested stockholder.

In general, Section 203 defines “business combination” to include the following:

●

any merger or consolidation involving the corporation and the interested stockholder;

●

any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

●

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

●

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

●

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

Indemnification and Limitation of Liability

Our amended and restated certificate of incorporation and bylaws require us to indemnify our directors, officers, employees and agents against the costs (including fines, judgments and attorney fees) from involvement in legal proceedings arising from their position or service, provided that the person seeking indemnification acted:

●

in good faith;

●

in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation; and,

●

with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

The amended and restated certificate of incorporation and bylaws allow us to buy indemnification insurance for this purpose.

Our certificate of incorporation provides that, to the fullest extent permissible under Delaware law, no director shall be personally liable to the corporation or its stockholders for monetary damages for breach of a fiduciary duty as a director. However, this provision does not eliminate the duty of care, and in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief that will remain available under Delaware law. In addition, each director will continue to be subject to liability for (a) breach of the director’s duty of loyalty to us or our stockholders, (b) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) violating Section 174 of the Delaware General Corporation Law, or (d) any transaction from which the director derived an improper personal benefit. The provision also does not affect a director’s responsibilities under any other law, such as the federal securities laws or state or federal environmental laws.

PLAN OF DISTRIBUTION

We may sell securities under this prospectus in public offerings:

●through one or more underwriters or dealers;

●through other agents;

●directly to investors; or

●through a combination of any of these methods.

We may price the securities we sell under this prospectus:

●at a fixed public offering price or prices, which we may change from time to time;

●at market prices prevailing at the times of sale;

●at prices calculated by a formula based on prevailing market prices;

●at negotiated prices; or

●in a combination of any of the above pricing methods.

If we use underwriters for an offering, they will acquire securities for their own account and may resell them from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all the securities of the series offered by the prospectus supplement. The public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may change from time to time. Only underwriters named in a prospectus supplement are underwriters of the securities offered by that prospectus supplement.

We may offer our securities in “at the market” offerings, with the meaning of Rule 415(a)(4) of the Securities Act, into an existing trading market on terms described in the applicable prospectus supplement. Underwriters and dealers may participate in any “at the market” offering.

We may also sell securities directly or through agents. We will name any agent involved in an offering and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agents will act on a best-efforts basis.

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions of these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

We may provide agents and underwriters with indemnification against certain civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to such liabilities. Underwriters or agents may engage in transactions with us, or perform services for us, in the ordinary course of business. We may also use underwriters or agents with whom we have a material relationship. We will describe the nature of any such relationship in the prospectus supplement.

An underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act . Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriter to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. These activities may cause the price of our securities to be higher than it would otherwise be on the open market. The underwriter may discontinue any of these activities at any time.

All securities we offer, other than common stock, will be new issues of securities, with no established trading market. Underwriters may make a market in these securities, but will not be obligated to do so and may discontinue market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

In addition, counsel that will be named in the applicable prospectus supplement will pass upon the validity of any securities offered under the applicable prospectus supplement for any underwriters or agents.
