October 19, 2023 updated by: Jon Houck, The Mind Research Network

Cerebellar Repetitive Transcranial Magnetic Stimulation (rTMS) for Reduction of Negative Affect and Treatment of Alcohol Use Disorder

The objective of the current study is to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on self-reported negative affect, cerebellar brain activation and alcohol use outcomes in alcohol use disorder (AUD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To achieve study aims, 34 treatment seeking adults with AUD will be recruited from local intensive outpatient (IOP) treatment programs and randomized to treatment with either inhibitory 1Hz rTMS to cerebellar vermis given daily for 2 weeks (total of 10 sessions) or sham. Alcohol use outcomes, self-reported negative affect, and craving will be obtained at baseline, 1 day, 1 week and 6 weeks following rTMS termination. An fMRI scan during a Stroop task will be obtained at baseline and 1 day after the final rTMS session.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Able to provide voluntary informed consent;
  • Have at least 4 heavy drinking days (≥ 5 drinks per day for men, and ≥4 for women) in the past 60 days;
  • Currently receiving treatment for alcohol use disorder.

Exclusion Criteria:

  • Severe neurological conditions (TBI/stroke/history of a seizure/dementia and other significant cognitive illnesses);

  • Have previously undergone rTMS (to assure the blind is effective);
  • Personal or familial (in first degree relatives) history of epilepsy;
  • Any contraindication for Magnetic Resonance Imaging (MRI) or TMS including metal shards or certain implants (pacemakers etc.) in the body.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Cerebellar rTMS
Cerebellar rTMS. 1Hz repetitive transcranial magnetic stimulation (rTMS) to cerebellar vermis.
Device: Repetitive transcranial magnetic stimulation (rTMS)
Repetitive transcranial magnetic stimulation (rTMS). Participants will undergo 10 daily sessions (Mon-Fri) of 30 minutes of 1Hz stimulation, for a total of 1800 pulses delivered.
Sham Comparator: Sham TMS
Sham TMS. Sham transcranial magnetic stimulation to cerebellar vermis.
Device: Sham transcranial magnetic stimulation
Sham transcranial magnetic stimulation (TMS). Participants will undergo 10 daily sessions (Mon-Fri) of 30 minutes of sham stimulation. Sham stimulation will imitate the active rTMS but does not have active stimulation.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to drinking relapse as measured by the Time Line Follow Back
Time Frame: 8 weeks
Time to drinking relapse as measured by the Time Line Follow Back from baseline in days.
8 weeks
Change in percent days abstinent as measured by the Time Line Follow Back
Time Frame: 3 weeks
Change in percent days abstinent as measured by the Time Line Follow Back from the 90 days prior to day 1 to day 14-21 (post-treatment).
3 weeks
Change in self reported negative affect as measured by the Promise anger, anxiety and depression scales
Time Frame: 2 weeks
Change in self reported negative affect as measured by the Promise anger, anxiety and depression scale T scores from baseline to day 15 (post-treatment).
2 weeks
Change in cerebellar brain activation as indicated by percent signal change in the medial cerebellum during incongruent minus congruent trials during a multisensory Stroop task during fMRI
Time Frame: 2 weeks
Change in cerebellar brain activation as indicated by percent signal change in the medial cerebellum during incongruent minus congruent trials during a multisensory Stroop task during fMRI from baseline to day 15 (post-treatment). This will be calculated using a mask derived from preliminary data from a sample of 33 individuals with AUD at a single timepoint. Activation in this brain region was correlated with depression, anxiety, and recent drinking. Manuscript describing this result is under review (Wilcox et al.), and another manuscript describes the task in question (Wilcox et al. 2014 Cognitive Control Network Function in Alcohol Use Disorder Before and During Treatment With Lorazepam. Subst Use Misuse.
