Primary Purpose: Treatment

Further study details as provided by Palatin Technologies:

Primary Outcome Measures:
  • The Primary Efficacy Endpoint is Change From Baseline to End of Study in the Number of Satisfying Sexual Events (SSE) [ Time Frame: 4 - 12 weeks from baseline to end of study (total study duration 20 weeks). Baseline was the 4-week single-blind placebo period. ] [ Designated as safety issue: No ]
    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.


Secondary Outcome Measures:
  • Change From Baseline to End-of-Study in Arousal Domain Score From Female Sexual Function Index [ Time Frame: 4-12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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).

  • Satisfaction With Arousal as Measured by GAQ Question 1 [ Time Frame: 4-12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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).

  • Desire Domain From Female Sexual Function Index [ Time Frame: 4-12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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).

  • Satisfaction With Desire as Measured by GAQ Question 2 [ Time Frame: 4-12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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).

  • Quality of Relationship With Partner as Measured by GAQ Question 4 [ Time Frame: 4-12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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 Total Score [ Time Frame: 4 - 12 weeks from baseline to end of study (total study duration 20 weeks) ] [ Designated as safety issue: No ]
    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.
