Palatin Technologies Reports Positive Results For Phase 2B Bremelanotide Female Sexual Dysfunction Trial

Stocks in this article: PTN

Detailed analysis of the data results in this trial will be presented at upcoming medical and scientific conferences and publications. Based on the results of discussions with the FDA and external advisors regarding the results of this trial and further development steps,  Phase 3 activities are anticipated to start in the second-half of calendar year 2013.

Study Design Approximately 400 premenopausal women, diagnosed with female sexual arousal disorder, hypoactive sexual desire disorder or both, were enrolled in the study.  Patients were treated for 16 weeks and were randomized to one of four double-blind treatment groups and received placebo or bremelanotide doses of 0.75, 1.25, or 1.75 milligrams.

The trial was a multi-centered, randomized, placebo-controlled, parallel-group dose-ranging trial designed to evaluate the safety and efficacy of three subcutaneous (SC) bremelanotide fixed doses intended for on-demand use in premenopausal females with FSD. The pharmacokinetics of SC bremelanotide was also assessed during this trial.

The objectives of the Phase 2B trial were to demonstrate and identify safe and effective SC doses of bremelanotide and to define endpoint measurements to support transition to Phase 3 clinical studies and activities.

About Female Sexual Dysfunction Female Sexual Dysfunction (FSD) covers multi-factorial conditions that have anatomical, physiological, medical, psychological and social components. FSD includes four categories: Sexual Desire Disorders (hypoactive sexual desire disorder [HSDD], sexual aversion disorder), Female Sexual Arousal Disorder (FSAD), Female Orgasmic Disorder (FOD), and Sexual Pain Disorders (dyspareunia, vaginismus). To establish a diagnosis of FSD, one or more of these disorders must be associated with personal distress, as determined by the affected women. In the 2008 PRESIDE study (Prevalence of Female Sexual Problems Associated with Distress and Determinants of Treatment Seeking, reference: Obstet Gynecol. 2008 Nov: 112(5):970-8), Shifren and colleagues studied over 30,000 US women, reporting an age – adjusted point prevalence of sexual difficulties causing personal distress in 12% of respondents.

There are no drugs in the United States approved for the treatment of FSD.  Bremelanotide is an on-demand treatment for FSD and has the potential to transform the treatment of patients with FSD.

Bremelanotide for Sexual Dysfunction Palatin is developing subcutaneously administered bremelanotide for the treatment of FSD in premenopausal women diagnosed with FSD. 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).
