Evaluation of Varenicline and Accelerated TMS for Reduction of Nicotine Use
Massachusetts General Hospital
Summary
The goal of this clinical trial is to learn if a combination of varenicline and enhanced accelerated Transcranial Magnetic Stimulation (aTMS) works to help adults quit using nicotine products. Researchers will compare varenicline + active aTMS with a single dose of D-Clycloserine to varenicline + sham (inactive) aTMS with a placebo pill to see the effect of enhanced aTMS on reaching abstinence. The main question it aims to answer is: Does receiving active enhanced aTMS + varenicline lead to higher abstinence rates and lower nicotine craving? Participants will be asked to: * Complete 2 brain MRI scans * Take varenicline every day for 12 weeks * Quit using nicotine products at the end of the second week of varenicline * Complete one day of up to 20 TMS treatments * Take a single dose of D-Cycloserine medication on the day of TMS treatment * Complete 12 brief, weekly follow-up visits * Complete a brief daily survey each day that they take the study drug
Description
This is a 12-week randomized parallel design, double-blind, 2-arm clinical trial consisting of a combination of circuit-targeted TMS and varenicline in 30 adults aged 18-65 with nicotine use disorder who would like to reduce or stop nicotine use. Eligible participants will complete a baseline assessment of questionnaires and laboratory assessments. They will be randomized to receive varenicline and either active enhanced or sham TMS. Participants will be randomized at their baseline scan visit, during which they will undergo urinalysis, an fMRI scan, and a task and questionnaire battery. At t…
