NCT06228235

Brief Summary

The objective of this pilot clinical trial is to test the effects of different types of thinking strategies at the time of repetitive Transcranial Magnetic Stimulation (rTMS), applied to the left Dorsolateral Prefrontal Cortex (DLPFC), on smoking craving and brain activity. Participants will be individuals with moderate to high smoking dependence (smoking at least 8 cigarettes a day) who have no intention of quitting in the next 3 months and are eligible to have rTMS and functional magnetic resonance imaging (fMRI). The main objectives of the trial are:

  • upregulation of craving while viewing smoking-related images
  • downregulation of craving while viewing smoking-related images
  • no regulation of craving while viewing neutral smoking-unrelated images The order of sessions will be randomized across participants.

Outcome Measures

Primary Outcomes (2)

  • Change in self-reported smoking cravings

    Change in self-reported smoking cravings following high-frequency repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex paired with upregulation of craving during smoking cue exposure and downregulation of craving during smoking cue exposure relative to neutral cue exposure and no regulation of craving. Craving will be rated using the Tobacco Craving Questionnaire immediately following rTMS and on 1-4 Likert scale (1 = not at all; 4 = very much) in the course of cue exposure in fMRI.

    within 1 hour following the delivery of rTMS

  • Change in neural activation during regulation of craving

    Change in neural activation accompanying regulation of craving following high-frequency repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex paired with upregulation of craving during smoking cue exposure and downregulation of craving during smoking cue exposure relative to neurtral cue exposure and no regulation of craving. Neural activation will be measured using functional magnetic resonance imaging (fMRI).

    within 1 hour following the delivery of rTMS

Secondary Outcomes (2)

  • Change in delay discounting performance for cigarettes

    within 1 hour following the delivery of rTMS

  • Change in neural activation during delay discounting performance for cigarettes

    within 1 hour following the delivery of rTMS

Other Outcomes (1)

  • Resting-state brain activity

    within 1 hour following the delivery of rTMS

Study Arms (1)

Active rTMS

EXPERIMENTAL

There is a single arm in this open-label pilot study. All participants will receive active rTMS paired with different types of behavioral priming (upregulation of craving, downregulation of craving, no regulation of craving).

Device: Repetitive transcranial magnetic stimulation (rTMS)

Interventions

rTMS: rTMS is a form of non-invasive brain modulation. High-frequency rTMS will be administered. Pulses will be delivered at the frequency of 20Hz, in 50 trains of 40 pulses, 2000 pulses in total. Behavioral priming with regulation of craving: During rTMS, participants will look at pictures either related or unrelated to smoking. When looking at pictures related to smoking, participants will either upregulate cravings by thinking about the immediate positive experience of smoking or downregulate cravings by thinking about long-term negative consequences of smoking. When looking at neutral pictures unrelated to smoking, participants will not regulate their cravings.
