Double-Blind Naltrexone in Compulsive Sexual Behavior

This study has been completed.

University of Minnesota - Clinical and Translational Science Institute Identifier:
First received: April 27, 2007
Last updated: April 18, 2012
Last verified: April 2012
The goal of the proposed study is to evaluate the efficacy and safety of naltrexone in compulsive sexual behavior. Twenty subjects with DSM-IV compulsive sexual behavior will receive 8 weeks of naltrexone or placebo. The hypothesis to be tested is that naltrexone will be effective in reducing the urges to act out sexually in patients with compulsive sexual behavior. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.

Primary Outcome Measures:
  • Yale Brown Obsessive Compulsive Scale Modified for Compulsive Sexual Behavior (YBOCS) [ Time Frame: Assessed at each visit (every two weeks) until participation in the study was done (Week 8) ]
    The YBOCS is a reliable and valid, 10-item, clinician-administered scale that rates buying symptoms within the last seven days, on a severity scale from 0 to 4 for each item (total scores range from 0 to 40 with higher scores reflecting greater illness severity).

Secondary Outcome Measures:
  • Clinical Global Impression Scale - Severity [ Time Frame: Assessed at each visit (every two weeks) until participation in the study was done (Week 8) ]
    The CGI consists of two reliable and valid 7-item Likert scales used to assess severity in clinical symptoms. The scale ranges from 1 = "very much improved" to 7 = "very much worse." The CGI severity scale was used at each visit and ranges from 1 = "not ill at all" to 7 = "among the most extremely ill."
