Brief Summary:
Unblinded study of flibanserin for 8 weeks with responders randomized 1:1 to receive study medication alone vs. study medication and sex therapy for 12 additional weeks.

Condition or disease Intervention/treatment Phase
Hypoactive Sexual Desire Disorder Behavioral: sex therapy Drug: flibanserin Phase 4

Detailed Description:
This is an unblinded study to be conducted at a single research center, San Diego Sexual Medicine. Subjects meeting inclusion and exclusion criteria will receive flibanserin for an 8-week run-in period to differentiate between responders and non-responders. Responders will be determined by a score of 1-3 on the Patient Global Impression of Improvement (PGI-I) at 8 weeks from baseline, and will be randomized 1:1 to receive study medication alone vs. study medication and sex therapy for an additional 12 weeks.

Primary Outcome Measures :
  1. Desire domain of the Female Sexual Function Index (FSFI) [ Time Frame: at weeks 8 and 20 ]
    The primary objective of this study is to determine whether efficacy of flibanserin as determined by changes in the desire domain of the Female Sexual Function Index (FSFI) in women who respond to the study medication is greater when sex therapy is performed concomitant with the use of the medication.


Secondary Outcome Measures :
  1. Female Sexual Distress Scale (FSDS-DAO) [ Time Frame: at weeks 8 and 20 ]
    One secondary endpoint is to determine whether efficacy of flibanserin as determined by changes from baseline in the Female Sexual Distress Scale (FSDS-DAO) in women who respond to the study medication.

  2. Total score of the Female Sexual Function Index (FSFI) [ Time Frame: at weeks 8 and 20 ]
    One secondary endpoint is to determine whether efficacy of flibanserin as determined by changes from baseline in the total FSFI score respectively in women who respond to the study medication.


Other Outcome Measures:
  1. Patient Global Impression of Improvement (PGI-I) [ Time Frame: at weeks 8 and 20 ]
    The last goal is to identify those women with primary biologic based HSDD who respond to flibanserin and determine whether or not they feel concomitant sex therapy might be more beneficial.
