Brief Summary:
The purpose of this study is to determine the effect of GSK598809 as compared to placebo in preventing recently-quit smokers from going back to smoking.

Condition or disease Intervention/treatment Phase
Substance Dependence Drug: GSK598809 Drug: Nicotine Replacement Transdermal Patch Drug: Placebo Phase 2

Detailed Description:
The primary objective of this study is to evaluate the efficacy of GSK598809 compared to placebo for the prevention of relapse to smoking in recently abstinent smokers. Subjects who meet eligibility criteria will enter a 4-week open label treatment period during which they will receive nicotine replacement therapy (NRT). Subjects who have achieved at least one week of abstinence during the last week of an open label treatment period will be randomized to either GSK598809 or placebo in the double-blind treatment period and followed for another 12 weeks.

Arm Intervention/treatment
Placebo Comparator: Placebo Arm
Subjects in placebo arm will be taking placebo once daily for 12 weeks from week 5 to 16.
Drug: GSK598809
GSK598809 once daily for 12 weeks

Drug: Nicotine Replacement Transdermal Patch
All subjects will be treated during the 4 week open-label smoking cessation phase of the study. During Weeks 1-3, subjects will receive 21mg/day, and during Week 4, subjects will receive 14 mg/day. Those subjects who reached continuous abstinence on at least week 4 of the open-label phase will receive 7mg/day during Week 5 while taking GSK598809 or placebo.

Drug: Placebo
Placebo once daily for 12 weeks

Experimental: GSK598809 Arm
Subjects in GSK598809 arm will be taking GSK598809 once daily for 12 weeks from weeks 5 to 16.
Drug: GSK598809
GSK598809 once daily for 12 weeks

Drug: Nicotine Replacement Transdermal Patch
All subjects will be treated during the 4 week open-label smoking cessation phase of the study. During Weeks 1-3, subjects will receive 21mg/day, and during Week 4, subjects will receive 14 mg/day. Those subjects who reached continuous abstinence on at least week 4 of the open-label phase will receive 7mg/day during Week 5 while taking GSK598809 or placebo.
