Effects of Chantix on Relapse Prevention for Smoking Cessation
16. august 2010 oppdatert av: University of Pennsylvania
Validation of a Novel Paradigm for Screening Medications for Nicotine Dependence
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.

Detaljert beskrivelse
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.
