测试甲基苯丙胺使用障碍的加速 TMS 协议

2026年11月4日 更新者:University of Colorado, Denver

The investigators will evaluate the effects of an accelerated Transcranial Magnetic Stimulation (TMS) protocol of the left dorsolateral prefrontal cortex (DLPFC) for moderate to severe methamphetamine use disorder. This is a randomized parallel group design to assess feasibility and safety, evaluate efficacy (use, craving) and identify magnetic resonance imaging (resting state and cue craving) associated with group/outcomes.

详细说明

In a randomized double-blind parallel-group sham-controlled design (n=20) administer a 5-day accelerated iTBS protocol (40 treatments) to the left dorsolateral prefrontal cortex during a short inpatient stay. Magnetic resonance imaging will be completed pre-post TMS and participants will be followed for 12 weeks.

  2. Meets DSM-5 criteria for past-year moderate or severe methamphetamine use disorder;
  3. By Timeline Follow Back endorses at least 10 days of methamphetamine use out of the last month;
  4. Provides a urine drug screen positive for methamphetamine;
  5. Able to provide informed consent;
  6. No change in current psychiatric medication regimen, or medication free, for at least 4 weeks prior to study entry;
  7. Adequate English proficiency for study consent, and completion of the study instruments.

Exclusion Criteria:

武器和干预

参与者组/臂
干预/治疗
安慰剂比较:Sham TMS

Participants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of sham TMS, and then have weekly study visits for the next 12 weeks.

The TMS Cool-B65 A/P coil on its placebo side delivers electrical stimulation to the scalp (e.g., mimicking sensations associated with real stimulation) but does not provide magnetic stimulation to the targeted cortical structure.

实验性的:Active TMS

Participants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of active TMS, and then have weekly study visits for the next 12 weeks.

The TMS Cool-B65 A/P coil delivers magnetic stimulation to targeted cortical structure.

Weeks of continuous abstinence
大体时间:12 weeks

Number of weeks of continuous methamphetamine abstinence - sham vs. active as measured weekly by urine drug screen.

12 weeks
Days of methamphetamine use
大体时间:12 weeks

Number of days of methamphetamine use - sham vs. active as measured weekly by timeline followback interview.

12 weeks
Time to first methamphetamine use
大体时间:12 weeks

Time from end of TMS treatment to first methamphetamine use by timeline follow back or urine drug screen

12 weeks
Methamphetamine craving
大体时间:12 weeks

Craving as measured on the Stimulant Craving Questionnaire-Brief - sham vs. active. Each item is scored 0-6 (from Strongly Disagree=0 to Strongly Agree=6) with items #4 and #7 reverse scored. The investigators will average all 10 items as the total score, with higher scores indicating greater levels of craving.

12 weeks

大体时间:12 weeks

Craving as measured on visual analog scale - sham vs. active. Scored 0 to 100 with 0=no craving and 100=the most craving.
