  Purpose

This protocol is a 2-group double-blind placebo-controlled outpatient study investigating lisdexamfetamine for treatment of cocaine dependence. The investigators plan to enroll 100 subjects in a 14-week trial. The primary objectives will determine changes in cocaine use and secondary objectives will be cocaine craving and impulsivity.

Arms Assigned Interventions
Active Comparator: lisdexamfetamine
lisdexamfetamine 70mg/day
Drug: lisdexamfetamine Behavioral: cognitive behavioral therapy
Placebo Comparator: placebo
Placebo Comparator once per day
Drug: placebo Behavioral: cognitive behavioral therapy

Detailed Description:

This 2-group, double-blind, placebo-controlled, 14-week study (N=100) will investigate the efficacy of cognitive behavioral therapy plus lisdexamfetamine vs. placebo to treat cocaine dependence. We hypothesize that lisdexamfetamine will reduce cocaine use (primary outcome), as well as cocaine craving and impulsivity (secondary outcomes) vs. placebo.
