Effects of Chantix on Relapse Prevention for Smoking Cessation

Status Completed

Clinical Trial Summary

The goal of the proposed study is to validate an experimental paradigm to assess medication effects on smoking relapse following a brief (3-day) monitored period of smoking abstinence and a programmed cigarette lapse.

Clinical Trial Description

The proposed human experiment will test the validity of a novel paradigm that may provide a method for distinguishing compounds that are likely to have efficacy from those that are not, before they are tested in more costly large-scale clinical trials. Specifically, in a within-subject (cross-over) behavioral pharmacology investigation of 60 smokers, we will test the effects of varenicline versus placebo on smoking behavior in the natural environment following a 3-day period of monitored abstinence and a programmed cigarette lapse. A positive signal for varenicline effects in this study would provide support for the sensitivity of the paradigm. In addition, following completion of all assessments, participants will be followed in a 13-week open-label varenicline smoking cessation trial to determine whether response to varenicline in the laboratory study predicts clinical response in the open-label trial. ;
