NCT03827265

Brief Summary

The purpose of this study is to determine if brain stimulation using repetitive transcranial magnetic stimulation (rTMS) directed at different parts of the brain can decrease feelings of cigarette craving and symptoms of cigarette withdrawal, and also if men and women have different responses to rTMS. Participants will visit the University of California, Los Angeles (UCLA) five times: First, for in-person screening, then for four rTMS sessions, four three different brain regions. Everyone in the study will be assigned to all four treatment arms and they will take place in a random order. Before and after each rTMS session, a brief MRI will be performed, and participants will be asked to fill out questionnaires that describe how they are feeling.

Outcome Measures

Primary Outcomes (4)

  • Repetitive Transcranial Magnetic Stimulation (rTMS)

    Data from the brain regions that will be targeted with repetitive transcranial magnetic stimulation (rTMS) will be used to assess changes in craving, withdrawal, and affect

    4 weeks

  • Urge to Smoke Questionnaire

    A 10-item self-report questionnaire used to measure spontaneous craving

    4 weeks

  • Shiffman-Jarvik Withdrawal Scale

    A 25-item self-report questionnaire used to measure withdrawal

    4 weeks

  • Positive and Negative Affect Schedule (PANAS)

    A 20-item questionnaire used to measure mood

    4 weeks

Secondary Outcomes (2)

  • Baseline Magnetic Resonance Imaging (MRI)

    4 Weeks

  • Post-stimulation Magnetic Resonance Imaging (MRI)

    4 weeks

Study Arms (4)

TMS on SFG

EXPERIMENTAL

Device: repetitive transcranial magnetic stimulation (real) Transcranial magnetic stimulation (TMS) uses magnetic stimulation to change patterns of activity in your brain. This arm will target the superior frontal gyrus (SFG). Other Name: rTMS (active stimulation)

Device: repetitive transcranial magnetic stimulation (rTMS)

TMS on PPC

EXPERIMENTAL

Device: repetitive transcranial magnetic stimulation (rTMS) Transcranial magnetic stimulation (TMS) uses magnetic stimulation to change patterns of activity in your brain. This arm will target the posterior parietal cortex (PPC). Other Name: rTMS (active stimulation)

Device: repetitive transcranial magnetic stimulation (rTMS)

TMS on dlPFC

EXPERIMENTAL

Device: repetitive transcranial magnetic stimulation (rTMS) Transcranial magnetic stimulation (TMS) uses magnetic stimulation to change patterns of activity in your brain. This arm will target the dorsolateral prefrontal cortex (dlPFC). Other Name: rTMS (active stimulation)

Device: repetitive transcranial magnetic stimulation (rTMS)

TMS on v5

PLACEBO COMPARATOR

Device: repetitive transcranial magnetic stimulation (rTMS) Transcranial magnetic stimulation (TMS) uses magnetic stimulation to change patterns of activity in your brain. This arm will target visual cortex (v5). Other Name: rTMS (sham stimulation)

Device: repetitive transcranial magnetic stimulation (rTMS)

Interventions

A rTMS system is an electromagnetic device that non-invasively delivers a rapidly pulsed magnetic field to the cerebral cortex in order to activate neurons within a limited volume without inducing a seizure. The device is intended to be used to treat patients meeting clinical criteria for MDD as defined in the Diagnostic and Statistical Manual of Mental Illnesses, Fourth Edition (DSM-IV). This guidance is issued in conjunction with a Federal Register notice announcing the classification of rTMS systems for the treatment of MDD.
