Trial Outcomes & Findings for Bremelanotide in Premenopausal Women With Female Sexual Arousal Disorder and/or Hypoactive Sexual Desire Disorder (NCT NCT01382719)

A total of 1142 subjects were screened at 69 medical sites in the US and Canada, 612 subjects were enrolled, and 488 subjects entered the single-blind placebo treatment period; 397 were randomized, and 394 were dosed with randomized treatment.

A total of 91 subjects were not randomized due to failing the resting blood pressure criteria (36), withdrawal of consent (24), being lost to follow-up (9), adverse events (5), non-compliance (5), and other reasons (12).

Bremelanotide in Premenopausal Women With Female Sexual Arousal Disorder and/or Hypoactive Sexual Desire Disorder

The primary efficacy endpoint is change from baseline to end of study in the number of satisfying sexual events (SSEs), computed as the number of events during the last 4 weeks of treatment with FSEP-R Q10 = "Yes" minus the number of baseline events with FSEP-R Q10 = "Yes." Efficacy analyses were done with the MITT population which consisted of all randomized subjects who took at least 1 dose of double-blind treatment after the 2 in-clinic doses of double-blind medication and who had at least 1 follow-up visit (Visit 10 or later) to ensure that FSEP-R data were reviewed and confirmed by the investigative site.

The FSFI is brief self-report questionnaire that measures female sexual function. The change from baseline to end of study in the arousal domain were obtained from the FSFI Q3 through Q6. The score range is 0-5. For each of the 2 time points, the score was computed programmatically using the algorithm described by Rosen \[6\], resulting in a score from 0 (min) to 6 (max).

This is the change in Baseline to End-of-Study in Satisfaction with Arousal as measured by GAQ Question 1. GAQ (Global Assessment Questions) is a questionnaire that evaluates overall satisfaction level experienced while using the study drug. Question 1 is "Compared to the start of the study (prior to taking the study drug), how would you describe your satisfaction with your arousal while using the study drug?" The score range is 1 (very much worse) to 7 (very much better).

The FSFI is brief self-report questionnaire that measures female sexual function. The change from baseline to end of study in the desire domain were obtained from the FSFI Q1 and Q2. The score range is 1-5. For each of the 2 time points, the score was computed programmatically using the algorithm described by Rosen \[6\], resulting in a score from 0 (min) to 6 (max).

This is the change in Baseline to End-of-Study in Satisfaction with Desire as Measured by GAQ Question 2. GAQ (Global Assessment Questions) is a questionnaire that evaluates overall satisfaction level experienced while using the study drug. Question 2 is "Compared to the start of the study (prior to taking the study drug), how would you describe your satisfaction with your desire while using the study drug?" The score range is 1 (very much worse) to 7 (very much better).

This is the change in Baseline to End-of-Study in Quality of Relationship with Partner as Measured by GAQ Question 4. GAQ (Global Assessment Questions) is a questionnaire that evaluates overall satisfaction level experienced while using the study drug. Question 4 is "Compared to the start of the study (prior to taking the study drug), how has taking the study drug changed your relationship with your partner?" The score range is 1 (very much worse) to 7 (very much better).

FSDS-DAO (Female Sexual Distress Scale - Desire/Arousal/Orgasm) is an assessment tool to measure female sexual distress. The change from baseline to end of study in the FSDS-DAO (total score) was measured. There are 15 questions, eg, "How often do you feel: Distressed about your sex life" and the score range was 0 (Never), 1 (Rarely), 2 (Occasionally), 3 (Frequently), 4 (Always). The score for each subject at each time point was computed as the sum of the scores from the 15 questions, resulting in a possible score at each time point between 0 and 60.
