  • Ages 21 to 65 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Individuals from 21-65 years old currently enrolled in an intensive outpatient treatment program.

Who cannot join

  • Participants will be excluded if they are not between 21-65 years old, have current or prior dependence (DSM-IV, because a DSM-V version of the SCID is not yet available) on prescription or psychoactive drugs other than cocaine, alcohol, or nicotine but including marijuana; past 6 month abuse of any prescription or psychoactive drugs excluding cocaine, marijuana, alcohol or nicotine, lifetime history of head injury with loss of consciousness, being pregnant or breast feeding, unstable medical illness (e.g., hypertension, diabetes, myocardial infarction), presence of ferromagnetic metal in their body, history of seizures. Additionally, to mitigate any potential risk of seizures. As mentioned above, all participants will receive the Clinical Institute Withdrawal Assessment of Alcohol (CIWAar) assessment before each TMS visit.

About this study

Official title: 10 Days of Medial Prefrontal Cortex Theta Burst Stimulation (MPFC cTBS) as a Tool to Improve Clinical Outcomes and Decrease Frontal-striatal Reactivity to Cues Among Treatment-engaged Cocaine and Alcohol Users

The goal of this double-blind sham controlled study is to evaluate the effeicacy of continuous theta burst stimulation to the frontal pole as a tool to decrease drug cue reactivity and improve treatment outcomes in treatment-engaged cocaine and alcohol users. All participants will be randomized to receive 10 days of real or sham rTMS to the frontal pole. Brain imaging data and behavioral assessments will be collected at 4 time points - before TMS, after 10 days of TMS, 1 month follow up and 2 month follow up.

Read the detailed description

Cocaine dependence is a particularly difficult substance use disorder to treat. There is currently a lot of scientific inertia focused on the development of novel, neural circuit based strategies for intervention. A prior NARC funded pilot project in non-treatment seeking cocaine users demonstrated that a single session of medial prefrontal cortex theta burst stimulation (MPFC cTBS) decreases baseline frontal-striatal activity in limbic regions and decreases neural responses to cocaine uses. The effects of a single session however, erode over the first few hours after treatment. Sustainable effects require multiple days of treatment. GOAL: The next steps in pursuing this as a novel treatment are to 1) apply it to treatment-engaged patients and 2) determine whether several sessions of cTBS will produce sustainable and clinically-meaningful changes in cocaine use among these patients.

DESIGN: Treatment-engaged cocaine users and heavy alcohol users will be randomized to receive 10 sessions of real or sham LTD-like MPFC cTBS. This will be achieved by leveraging our existing partnership with the MUSC Center for Drug and Alcohol Programs (CDAP) and the Veterans Administration Substance Abuse Treatment Center Program (SATC) - which both provide a 4 week intensive outpatient treatment program. MPFC cTBS will be given during weeks 2 and 3 of the program. Functional MRI data and clinical assessments will be acquired during weeks 1, 4, and at participant's 1 month and 2 month Accountability/Continuity visits. Hypothesis: real cTBS treatment will enhance clinical outcomes (Aim 1 - including retention rates, number of clean urine drug screens during CDAP treatment, relapse rates at 1 and 2 months) and will produce a sustainable decrease in neural reactivity to cocaine cues (Aim 2 - week 1 versus week 4, 1 month \& 2 month follow ups).

What participants receive

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

  • Real cTBSDevice

    This will be delivered with the Magventure Magpro system; 3600 pulses with the active sham coil (double blinded using the USB key)

  • Sham cTBSDevice

    This will be delivered with the sham Magventure Magpro system; 3600 pulses with the active sham coil (double blinded using the USB key)

What is being measured

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

  1. Change in Drug cue reactivity

    The effect of real versus sham cTBS on drug cue reactivity will be assessed by comparing the brain activity in the limbic system

    Measured: Baseline visit and 1 month follow up

Secondary outcomes (1)
  1. Number of Clean Urine Drug Screens

    The effect of real versus sham cTBS on the number of clean urine drug screens will be assessed at the 1 and 2 month follow up.

    Measured: 1 month and 2 month follow up

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Real cTBS in people with Cocaine Dependence and Alcohol Dependence, run by Medical University of South Carolina at 2 sites 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 1 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 12 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Change in Drug cue reactivity (time frame: Baseline visit and 1 month follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 12 Mar 2020.
