Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
at weeks 8 and 20

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
at weeks 8 and 20
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.
at weeks 8 and 20

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
at weeks 8 and 20
