About this study

Official title: Topiramate to Aid Smoking Cessation in Recovering Alcohol Dependent Men

The purpose of this study is to determine whether topiramate is effective as an aid to smoking cessation for recovering alcohol dependent men.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TopiramateDrug

    Also called Topamax

    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).

  • PlaceboDrug

    Placebo/study medication will be administered in opaque capsules in an identical fashion to maintain the double-blind study design.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

4-week Continuous Abstinence From Smoking (time frame: Weeks 8-12 of treatment.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00802412, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jan 2017.
