Primary Outcome Measures:
  • Drug use
  • Cocaine use
  • Addiction severity
  • Clinical improvement

Estimated Enrollment: 140
Study Start Date: October 2002
Estimated Study Completion Date: June 2004
Detailed Description:
To assess the efficacy and safety of tiagabine in reducing cocaine use in subjects with cocaine dependence. It is hypothesized that tiagabine treatment, compared to placebo, will be associated with fewer days of cocaine use as assessed by self-report confirmed with urine assays for benzoylecgonine (BE). This is a double-blind, placebo-controlled, parallel-group design study, in which, after screening and a 2-week baseline assessment period, subjects will be equally randomly assigned to 1 of 2 treatment groups, tiagabine or matched placebo.
