NCT04083144

Brief Summary

The purpose of this study is to investigate the effect of deep repetitive transcranial magnetic stimulation (rTMS) using the insula H-coil on smoking outcomes in smokers receiving varenicline. It is hypothesized that active deep rTMS will improve abstinence rates, attenuate craving and reduce cigarette consumption and dependence severity.

Study Arms (2)

Deep rTMS active + Varenicline

ACTIVE COMPARATOR

Participants undergoing deep rTMS (active) for 4 weeks (5 sessions/week) along with 12 weeks of varenicline.

Device: Deep Repetitive Transcranial Magnetic Stimulation (Active)Drug: Varenicline

Deep rTMS sham + Varenicline

SHAM COMPARATOR

Participants undergoing deep rTMS (sham) for 4 weeks (5 sessions/week) along with 12 weeks of varenicline.

Device: Deep Repetitive Transcranial Magnetic Stimulation (Sham)Drug: Varenicline

Interventions

Active deep rTMS (10 Hz) using the H-coil to target the bilateral insula

Deep rTMS active + Varenicline

Sham deep rTMS using the H-coil. The sham coil is built into the same helmet as the active coil. It mimics the active coil with regards to acoustics and scalp sensations.

Deep rTMS sham + Varenicline

12 week course treatment of varenicline (0.5 mg/1 mg) using the standard dosage schedule for smoking cessation (Day 1-3: 0.5 mg daily; day 4-7: 0.5 mg twice a day; day 8-end of treatment: 1 mg twice a day).
