Study Summary

The purpose of this research study is to find out if an investigational drug, GSK598809 can help people who have very recently quit smoking; the investigators want to find out if continuing to take GSK598809 over six weeks can help prevent smokers from relapsing. To relapse means you "fall back" into smoking again after quitting. The investigators also want to find out if GSK598809 is safe to take without causing too many side effects.

Primary Outcome

The hypothesis is that those assigned to GSK598809 will demonstrate a higher rate of biochemically-verified, 4-week, continuous tobacco abstinence than those assigned to identical placebo at the end of the 6-week, double blind, treatment phase. Four-week continuous abstinence will be defined as Timeline Followback Calendar confirmation at study visit of smoking no cigarettes in the past 7 days, and expired air CO\<10ppm for 4 consecutive weeks (the last 4 weeks of the randomized phase)
