  Purpose

This proposal will test the efficacy of a promising pharmacological approach for the treatment of comorbid cocaine dependence and bipolar disorder. We propose a randomized, double blind, placebo controlled 12-week trial to test the efficacy of Divalproex sodium (Valproate) plus treatment as usual compared to placebo plus treatment as usual in decreasing cocaine use and stabilizing mood symptoms among patients with comorbid cocaine dependence and bipolar disorder. Treatment as usual includes the use of lithium carbonate for mood stabilization plus supportive psychosocial treatment.

Primary Outcome Measures:
  • This will be operationalized as an increase in the weekly mean proportion of self-report cocaine-abstinent (non-use) days confirmed by urine screen [ Time Frame: During the double-blind treatment phase ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of cocaine-abstinent days, proportion of participants with total abstinence, time to relapse to cocaine use, severity of cocaine use, cocaine craving scales, severity of HIV risk behavior [ Time Frame: During the double-blind treatment phase ] [ Designated as safety issue: No ]

Estimated Enrollment: 104

Detailed Description:

Bipolar disorder has the highest rate of association with cocaine and other substance use disorders than any other major severe psychiatric syndrome. This comorbidity represents a major treatment challenge and is associated with severe disability, morbidity, and heightened risk for suicide.

The aims of this study are:

  1. Examine the efficacy of valproate plus treatment as usual compared to placebo plus treatment as usual in decreasing cocaine use in patients with cocaine dependence and comorbid bipolar disorder.
  2. Determine whether primary vs. secondary cocaine dependence, bipolar subtype (depressed vs. manic/mixed) and the presence of additional substance use disorders moderate the association between treatment and cocaine use outcome.
  3. Assess the effects of medication compliance and mood symptoms as mediators of cocaine use outcome.
