About this study

The goal of this study is to determine whether transcranial magnetic stimulation (TMS) is an effective treatment in decreasing craving in individuals who habitually smoke cigarettes. The study consists of six total visits to MUSC; one for the consent process, two that will include MRI scans, and five that will include TMS administration. Compensation will be provided for each visit.

Read the detailed description

Prior and recent evidence suggests a role of medial prefrontal cortex (mPFC) in cigarette smoking. The present study will examine whether a five-day regimen of theta-burst transcranial magnetic stimulation (TMS) reduces cigarette smoking outside of the lab (examined through self-report and physiological measures) and motivation to smoke inside the lab (examined through behavioral tasks and functional MRI).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • continuous theta burst stimulation (real)Device

    Also called cTBS (active)

    a form of transcranial magnetic stimulation that noninvasively induces a depression in brain reactivity

  • continuous theta burst stimulation (sham)Device

    Also called cTBS (sham)

    a sham version of a form of transcranial magnetic stimulation that noninvasively induces a depression in brain reactivity

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent BOLD signal change in the MPFC

    The effect of real vs. sham cTBS to the leftt MPFC as a tool to modulate the brain response to craving will be assessed by comparing the brain activity in the limbic circuit before and after TMS.

    Measured: immediately after the treatment

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing continuous theta burst stimulation (real) in people with Smoking and Addiction, run by Medical University of South Carolina at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent BOLD signal change in the MPFC (time frame: immediately after the treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02939339, which also lists 28 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2018.
