NCT05974202

Brief Summary

The goal of this clinical trial is to compare the effects of active repetitive transcranial magnetic stimulation (rTMS) to sham (placebo) rTMS prior to cognitive-behavioral therapy (CBT) as a treatment for adults with cocaine use disorder. The main questions it aims to answer are:

  • Is rTMS safe and feasible as an augmentation for CBT for the treatment of cocaine use disorder?
  • What is the brain mechanism of rTMS?
  • Will active rTMS (compared to sham rTMS) followed by CBT help adults with cocaine use disorder achieve abstinence from cocaine? Participants will:
  • Have two brain MRI scans;
  • Undergo 3 weeks of daily rTMS (or sham) treatments (15 sessions), and;
  • Have 12 weeks of once-weekly cognitive-behavioral therapy for the treatment of cocaine use disorder. Researchers will compare active (real) rTMS to sham (placebo) rTMS. All participants will receive cognitive-behavioral therapy. The former principle investigator, Dr. Derek Blevins, has vacated his position (February 2025), and has transferred the principle investigator role to Dr. John Mariani, the STARS Clinic Director.

Outcome Measures

Primary Outcomes (4)

  • Percentage of participants receiving at least 10 out of 15 rTMS sessions

    Feasibility will be measured as the total percentage of participants who receive the defined number of rTMS sessions

    3 weeks

  • Number of participants in the active rTMS arm experiencing an rTMS-emergent adverse event

    Safety of rTMS will be measured by the absolute number of serious adverse events that occur in the active rTMS arm

    3 weeks

  • Percent change of medial prefrontal cortex and dorsal anterior cingulate cortex activity on fMRI during the Drug Stroop Task

    Neural mechanism will be evaluated by comparing the active and sham rTMS groups during the fMRI task by comparing baseline fMRI and post-rTMS fMRI measures

    3 weeks

  • Percentage of participants who achieve 3 weeks of abstinence during the final 12 weeks of the trial

    Efficacy regarding cocaine use outcomes will be evaluated by comparing the active and sham rTMS groups during the final 12 weeks of the trial while the participants are receiving cognitive behavioral therapy. 3 weeks of consecutive abstinence is defined as: 1. No cocaine use is self-reported per timeline followback; 2. At least 6 urine drug screens are completed during the 3 weeks of continuous abstinence, and all are negative (with the exception of any positive urine in the first 4 days of the first week of the three weeks of self-reported abstinence, as urine may remain positive for up to 4 days after an episode of use), and; 3. At least 1 urine drug screen is completed each week during the 3 weeks of self-reported continuous abstinence.

    12 weeks

Study Arms (2)

Active (high-frequency) rTMS

ACTIVE COMPARATOR

Daily high-frequency (10 Hz) repetitive transcranial magnetic brain stimulation for 3 weeks (15 sessions).

Device: Active H7-coil repetitive transcranial magnetic stimulation (rTMS)

Sham (placebo) rTMS

PLACEBO COMPARATOR

Sham rTMS uses the same device and mimics the auditory and scalp sensations without stimulating the brain.

Device: Sham H7-coil repetitive transcranial magnetic stimulation (rTMS)

Interventions

A magnetic current created by the device creates an electrical current in the brain to stimulate the medial prefrontal cortex and dorsal anterior cingulate cortex.

Active (high-frequency) rTMS

A sham coil is in the same helmet as the active coil. The sham coil mimics the sound, scalp sensations, and facial muscle activation caused by the active coil, but does not create an electrical current in the brain.

Sham (placebo) rTMS

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Used cocaine at least 9 days in the past 28 days, with at least weekly cocaine use;
  • Agree to no more than moderate alcohol consumption (\<15 drinks/week for men and \<8 drinks/week for women) and to avoid using amphetamine/methamphetamine and non-prescribed benzodiazepines or barbiturates; and
  • Women of childbearing potential must agree to use a method of contraception with proven efficacy and agree to not become pregnant during the study.

You may not qualify if:

  • Meets DSM-5 criteria for current moderate/severe major depressive episode, OCD, bipolar disorder, schizophrenia or any psychotic disorder other than transient psychosis due to substance use;
  • Hamilton Depression Rating Scale score \> 17;
  • Young Mania Rating Scale score \>10;
