Measuring Smoking Behaviors While Using Varenicline

Nicotine Dependence Clinical Trial

Official title: Assessment of Smoking Topography and Behaviors During Response to Varenicline

Status Completed

Clinical Trial Summary

This study will demonstrate the behavioral responses to varenicline, helping to better understand its mechanisms. Hypotheses for the study are to observe decreases in smoking topography and nicotine cigarette choice on varenicline, relative to placebo; and decreases on day 21 relative to day 7 during varenicline treatment. We also propose to examine if extended duration of treatment has clinical significance in decreasing smoking behaviors, thus increasing the efficacy of varenicline.

Clinical Trial Description

This study is designed to examine the behavioral responses a cigarette smoker may have to using varenicline. Behavioral responses may help to better understand its mechanisms which in turn could improve treatment outcomes. The primary hypothesis for the study is to observe decreases in smoking topography, an objective measure of smoking behavior or puffing, on varenicline, relative to placebo; and decreases on day 21 relative to day 7 during varenicline treatment. We will also examine puffing and nicotine cigarette choices during lab visits at baseline, and Days 7 and 21. We also propose to examine if extended duration of treatment has clinical significance in decreasing smoking behaviors, thus potentially increasing the efficacy of varenicline. ;
