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.

Condition Intervention Phase
Cocaine Dependence Drug: lisdexamfetamine/Behavior Therapy Other: placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Lisdexamfetamine Treatment for Cocaine Dependence

Primary Outcome Measures:
  • Cocaine-positive Urine Results [ Time Frame: 14 Weeks ]
    At each visit, subjects provided urine samples, which were analyzed for benzoylecgonine (BE; a cocaine metabolite). BE was assessed semi-quantitatively using the PROFILE® -V MEDTOXScan® Drugs of Abuse Test System, with cocaine positive tests equaling or exceeding 150 ng/mL.

Secondary Outcome Measures:
  • Drug Craving [ Time Frame: 14 Weeks ]

    On a weekly basis, patients completed measures of cocaine craving using the Minnesota Cocaine Craving Scale.

    The Minnesota Cocaine Craving Scale is a self report questionnaire and ranges from 0 to 100, 0 being "very little" to 100 being "very much".

Enrollment: 43

Arms Assigned Interventions
Active Comparator: lisdexamfetamine/Behavior Therapy
lisdexamfetamine 70mg/day plus Behavior Therapy
Drug: lisdexamfetamine/Behavior Therapy
Placebo Comparator: placebo
Placebo Comparator once per day
Other: placebo

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.
