Outcome Measures

Primary Outcomes (1)

  • The number of satisfactory sexual encounters based on event questionnaires on active drug as compared to placebo during double-blind treatment period episodes in the domestic setting.

    Efficacy is estimated by self reporting by subjects using daily event questionnaires, recorded within 24 hours after a sexual event. The number of events between a 4-week baseline establishment period will be compared with the number of events during the 8 week double-blind treatment period. In addition there is a 8 week run in period between the establishment period and the double blind treatment period for a total treatment period of 20 weeks.

    20 weeks

Secondary Outcomes (4)
