Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jsm12071-sec-0001" sec-type="section"> <title>Introduction</title> <p>Female sexual arousal disorder (FSAD) is a condition that can affect women of all ages and have a significant negative impact on emotional well‐being.</p> </sec> <sec id="jsm12071-sec-0002" sec-type="section"> <title>Aims</title> <p>The aim of this study is to prospectively evaluate the effects of CP‐866, 087, a selective mu‐opioid receptor antagonist, in premenopausal women with FSAD.</p> </sec> <sec id="jsm12071-sec-0003" sec-type="section"> <title>Methods</title> <p>The study included 51 women (20–45 years of age) with FSAD. All women received placebo and two of three planned doses of CP‐866, 087 (1, 3, and 10 mg) for 6 weeks in each of three double‐blind treatment periods. Efficacy was determined through a series of measures to assess sexual functioning, sexual activity, sexual distress, and perceived meaningful benefit as a result of treatment. In addition, a semi‐structured exit interview was conducted at the end of the fourth treatment period or withdrawal to provide a more in‐depth, qualitative description of the participants' symptoms, response to treatment, and treatment satisfaction to augment the quantitative assessments.</p> </sec> <sec id="jsm12071-sec-0004" sec-type="section"> <title>Main Outcome Measures</title> <p>The within‐subject differences from placebo in the change from baseline were compared across a range of measures of sexual function.

A qualitative analysis of the exit interview was conducted based on grounded theory methods.</p> </sec> <sec id="jsm12071-sec-0005" sec-type="section"> <title>Results</title> <p>Although improvements were seen with CP‐866, 087 in the key efficacy end points, there was no clinical treatment benefit over placebo. The exit interview analysis suggested that being part of the study and taking positive action to search for a solution to the women's sexual disorder may have been a significant factor in the behavioral changes that were seen, as opposed to the drug treatment itself.</p> </sec> <sec id="jsm12071-sec-0006" sec-type="section"> <title>Conclusions</title> <p>Discerning the potential benefit of pharmacotherapy in a heterogeneous condition such as FSAD is challenging. Participation in a clinical trial combined with a commitment to actively engage in sexual activity may in itself create an environment that is conducive to symptom improvement. <bold>Orri M, Abraham L, and Giraldi A.
