A Comparative Effectiveness & Long Term Health Study in Wisconsin Smokers
In Brief
A Phase 4 clinical trial evaluating Varenicline, Nicotine lozenge, and 1 other intervention for Smoking Cessation and 2 related conditions. Completed, enrolled 1,086 participants across 2 sites.
Detailed Summary
The overall purpose of this research is two-fold. First, the two smoking cessation medication treatments with the strongest evidence of effectiveness have never been directly compared. This research will determine how these two treatments compare in effectiveness in a head-to-head trial, and which types of smokers benefit most from each. Second, much of the data on smoking and health come from studies from many years ago. Today's smokers differ from earlier smokers in many ways that could influence the impact of smoking on health (e.g., weight, sex, diet, socio-economic status); the proposed work will determine how smoking cessation affects cardiovascular and pulmonary health in today's smokers.

Timeline
Interventions
Participants will receive 12 weeks of pharmacotherapy during the post-quit period plus an additional 7 day pre-quit run-in. Participants will be asked to take a 0.5 mg pill once a day for the first 3 days and then increase to a 0.5 mg pill twice a day (8 hours apart) for 4 days. On the 8th day, their target quit date, they will increase to their target maintenance dose of a 1 mg pill twice daily. If participants report significant adverse events such as nausea, a dose reduction to two 0.5 mg doses per day will be advised.
Participants will receive 12 weeks NRT. Participants will be given 2 mg or 4 mg lozenges based on morning smoking latency, and will be given package insert use instructions. Medication use will start on the morning of their assigned quit day. They will be urged to use at least 5 pieces/day, unless this amount produces adverse effects.
Participants will receive 12 weeks NRT. Patch dosing will be 8 weeks of 21 mg, then 2 weeks of 14 mg, then 2 weeks of 7 mg (those smoking 5-10 cigs/day will receive reduced patch dosing). Medication use will start on the morning of their assigned quit day. They will be urged to use 1 patch/day, unless it produces adverse effects.
