Brief summary

A Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel-group Trial with an optional Open-label Extension to evaluate the efficacy of bremelanotide (BMT), administered subcutaneously (SC) on an as needed basis for the treatment of HSDD (with or without decreased arousal) in premenopausal females.

Detailed description

This will be a multicenter, randomized, placebo-controlled, parallel group study in up to 80 sites in the United States of America (USA) and Canada to evaluate the efficacy and safety of a fixed dose of SC BMT versus placebo on an as-needed basis under conditions of home use in premenopausal women with HSDD (with or without decreased arousal). The study will consist of 2 phases: (1) Core Study: 4-week no-treatment qualification period, a 4-week single-blind placebo treatment period (baseline), and a 24-week double-blind treatment period where participants will self-administer placebo or BMT 1.75 mg SC via an autoinjector; and (2) Extension Phase: a 52-week open-label treatment period during which all subjects will receive BMT 1.75 mg. Primary Objective • To evaluate the efficacy of bremelanotide (BMT), administered subcutaneously (SC) on an as needed basis for the treatment of HSDD (with or without decreased arousal) in premenopausal females. Secondary Objectives * To evaluate the efficacy of BMT in premenopausal women in the double-blind Core Study, as assessed by subject responses to questionnaires measuring sexual function, treatment satisfaction, and distress associated with sexual dysfunction. * To evaluate the safety of BMT in premenopausal women in the double-blind Core Study. * To evaluate the safety of long-term therapy with BMT in the open label Extension Phase. * To evaluate the efficacy of long-term therapy with BMT in the open-label Extension Phase.

Efficacy of a Fixed Dose of Bremelanotide as Measured by FSDS-DAO (Item 13)

As measured by the change from baseline to End-of-Study of the Core Study in the bothered by low desire item from the FSDS-DAO (item 13). Responses range from 0 (never) to 4 (always). Lower scores on this scale represent an increase in sexual desire and indicate a better outcome. Higher scores indicate a worse outcome.

Time frame: 8 weeks baseline plus 24 weeks (Main Study), 52 Weeks (OLE)

Efficacy of a Fixed Dose of Bremelanotide, as Measured by the Change in Baseline to End of Study in the Scored Time Spent Being Concerned by Difficulty With Sexual Arousal (Q14) From the FSDS-DAO

FSDS-DAO = Female Sexual Distress Scale - Desire/Arousal/Orgasm. The FSDS-DAO is a validated 15-item self-assessment of sexual feelings and problems. Scores on this scale range from 0 (never) to 4 (always). Decreased scores indicate improvement. A higher score on this scale indicates a worse outcome.
