NCT ID: NCT02147132

Last Updated: 2018-12-05

Results Overview

Subjects will be given a special electronic cigarette lighter called Quitbit.The electronic lighter will record a timestamp for each time the lighter is used to light a cigarette.

Subjects assigned to this arm will receive Placebo Nasal Spray first (Week 1), followed by Nicotine Nasal Spray (Week 2), followed by Varenicline (Weeks 3-4), followed by a washout period (Week 5) and then Placebo Varenicline (Weeks 6-7). Nicotine Nasal Spray: 7 days. 1 mg/dose, up to 40x/day. Varenicline: 14 days. Days 1-3: 0.5 mg once daily; Days 4-7: 0.5 mg twice daily; Days 8-14: 1 mg twice daily. Placebo Nasal Spray: 7 days. 1 mg/dose, up to 40x/day.1 mg/dose, up to 40x/day. This will appear similar to the Nicotine Nasal Spray, but will be a placebo. Placebo Varenicline: 14 days. Days 1-3: 0.5 mg once daily; Days 4-7: 0.5 mg twice daily; Days 8-14: 1 mg twice daily. This will appear identical to the drug Varenicline, but will be a placebo.

PRIMARY outcome

Timeframe: 7 weeks

Population: Varenicline and placebo varenicline analysis populations are less than 7 because 1 participant was lost to follow-up and provided no data for these assigned medications.

Subjects will be given a special electronic cigarette lighter called Quitbit.The electronic lighter will record a timestamp for each time the lighter is used to light a cigarette. Data will be collected from the lighter at each study visit. This will measure how many cigarettes are smoked and when.

SECONDARY outcome

Timeframe: 7 weeks

Population: Varenicline and placebo varenicline analysis populations are less than 7 because 1 participant was lost to follow-up and provided no data for these assigned medications.

The Quitbit lighter will measure how many cigarettes are smoked per day. In addition to the Quitbit lighter measurement, the Timeline Follow Back (TLFB) form will be filled out for each subject to measure use, as well.

Carbon monoxide (CO) in each participant's breath will be tested. A CO level less than or equal to 8 parts-per-million will be used to verify reports of no smoking.
