Behavioral Counseling and Nicotine Replacement Therapy or Varenicline in Helping Smokers Quit

Trial Status: Closed to Accrual

This pilot, randomized phase IV trial studies behavioral counseling and nicotine replacement therapy or varenicline in helping smokers quit. Nicotine replacement therapy patch may help stop nicotine cravings and relieves symptoms that occur when a person is trying to quit smoking. Varenicline may help people stop smoking by acting the same way nicotine acts in the brain. It is not yet known whether nicotine replacement therapy is more effective than varenicline in helping smokers quit.

PRIMARY OBJECTIVES:

I. To conduct a (proof of concept) clinical trial comparing the effectiveness of varenicline versus (vs.) nicotine replacement therapy (NRT: patch) for smoking cessation among smokers high (intrinsic reward sensitivity [IRS]+) and low (IRS-) in reward sensitivity.

II. To evaluate the relationship between late positive potential (LPP) defined reward sensitivity and other measures of reward system deficiency including anhedonia and reward valuation.

OUTLINE: Participants are randomized to 1 of 2 treatment arms.

ARM I: Participants receive varenicline orally (PO) twice daily (BID) for 12 weeks (once daily [QD] on days 1-3 of week 1). Beginning on day 8, participants also receive placebo NRT patch for 11 weeks.

ARM II: Participants receive varenicline placebo PO BID for 12 weeks (QD on days 1-3 of week 1). Beginning on day 8, participants also receive NRT patch for 11 weeks.

In both arms, participants undergo brief individual behavioral smoking cessation counseling per recommended standard for use with pharmacotherapy during the 12 week active treatment phase, consisting of 4 in-person counseling visits, 4 telephone call visits, and 2 brief supportive telephone calls.

After completion of study treatment, participants are followed up at 3 and 6 months.
