Primary Outcome Measures:
  • 4-week Continuous Abstinence From Smoking [ Time Frame: Weeks 8-12 of treatment. ]
    This measure indicates the proportion of participants who did or did not smoke any cigarettes during the final 4 weeks of treatment, which represented weeks 8-12 of study participation.

Secondary Outcome Measures:
  • Percent Relapsing to Any Drinking or Illicit Drug Use [ Time Frame: 12-week treatment phase, 36-week combined treatment and follow-up ]
    Alcohol or illicit drug use during treatment or follow up.

Enrollment: 132
Study Start Date: January 2009
Study Completion Date: June 2015
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
The subjects for the proposed study will be 180 currently smoking, treatment-seeking male veterans with alcohol and nicotine dependence. Ninety subjects will be randomized to the topiramate arm and 90 subjects will be randomized to the placebo group.
Drug: Topiramate
Topiramate will be titrated over 5 weeks to a maximum dosage of 200 mg according to the following schedule: 25mg daily for days 1-7, 50mg daily for days 8-14, 75mg daily for days 15-21, 100mg daily for days 22-28, 150mg daily for days 29-35, 200mg daily for days 36-42. Maximum dosage will be maintained for 6 weeks, followed by a one-week taper-off period (100mg daily for 4 days and 50mg daily for 3 days).
Other Name: Topamax
Placebo Comparator: Placebo
90 participants, will receive matching placebo
Drug: Placebo
Placebo/study medication will be administered in opaque capsules in an identical fashion to maintain the double-blind study design.

Detailed Description:
This study is a 12-week, double-blind, placebo-controlled trial to test the efficacy of topiramate versus placebo as an aid to smoking cessation for recovering alcohol dependent men. Another aim of the study is to explore whether or not topiramate reduces relapse to alcohol use in patients with comorbid alcohol and nicotine dependence. All participants will receive a standardized psychosocial intervention in combination with the medication (or placebo). Following completion of the treatment phase of the study, participants will enter a 24-week follow-up period during which the longer-term outcome of the intervention will be assessed.
