What You Need to Know Before You Apply

What is the purpose of this trial?

The trial aims to understand how theta burst stimulation, a type of transcranial magnetic stimulation (TMS), affects cravings and brain activity in people who use methamphetamine. TMS is a non-invasive treatment that uses magnetic fields to stimulate nerve cells in the brain. Participants will be divided into groups to receive either real or sham (placebo) TMS on different days for comparison. The trial seeks individuals who have used methamphetamine, experience cravings, and are living with HIV. As an unphased trial, it offers participants the opportunity to contribute to groundbreaking research that could lead to new treatments.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this transcranial magnetic stimulation is safe for meth addiction?

Research has shown that theta burst stimulation, a type of brain stimulation, has been tested in people with methamphetamine addiction. Studies found it to be generally well-tolerated. Most participants experienced only mild side effects, such as headaches or slight discomfort at the stimulation site. These effects were temporary and resolved on their own.

In these studies, no serious side effects were linked to the treatment. This suggests that theta burst stimulation is relatively safe for humans, at least in the short term. However, since this information comes from earlier research, anyone considering joining a trial should discuss potential risks with the study team. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using Transcranial Magnetic Stimulation (TMS) for meth addiction because it offers a unique, non-invasive way to potentially alter brain activity patterns associated with addiction. Unlike standard treatments like behavioral therapy or medication-assisted therapy, TMS targets specific brain areas using magnetic fields, which may help reduce cravings more directly. Specifically, the use of Theta Burst Stimulation (TBS) is promising because it can deliver results quickly, potentially in just a few sessions, compared to the longer timeframes needed for traditional therapies. This innovative approach could provide a new avenue for treating meth addiction with fewer side effects and a more targeted mechanism of action.

What evidence suggests that theta burst stimulation is effective for meth addiction?

Research has shown that theta burst stimulation (TBS), a type of brain stimulation, can help reduce cravings for methamphetamine. In this trial, participants will be divided into groups to receive either actual TBS or sham TMS on various days. One study found that TBS reduced cravings triggered by certain cues more effectively than a fake treatment. Another study demonstrated that TBS improved thinking skills and sleep quality in people with severe methamphetamine addiction. Additional research found that more frequent use of TBS led to a significant reduction in cravings. Overall, these findings suggest TBS could effectively manage methamphetamine addiction. ^{1 2 3 4 6}

Published Research Related to This Trial

Intermittent theta burst stimulation (iTBS) applied over the dorsolateral prefrontal cortex (DLPFC) significantly reduced craving for methamphetamine and improved cognitive function and sleep quality in 126 participants with severe methamphetamine use disorder over a four-week period.

The study suggests that rTMS is a promising and safe treatment option for methamphetamine use disorder, indicating the need for further large-scale trials to confirm these findings.

Intermittent theta burst transcranial magnetic stimulation for methamphetamine addiction: A randomized clinical trial. Su, H., Chen, T., Jiang, H., et al.[2021]

A proof-of-concept study involving 19 individuals with cocaine use disorder showed that administering intermittent theta-burst stimulation (iTBS) to the left dorsolateral prefrontal cortex was well-tolerated and safe, even in participants actively using cocaine.

Participants who completed at least 26 of the 30 iTBS sessions reduced their weekly cocaine use by 78% in spending and 70% in frequency, indicating that iTBS may effectively modulate addiction-related circuits and reduce substance use.

Accelerated Intermittent Theta-Burst Stimulation as a Treatment for Cocaine Use Disorder: A Proof-of-Concept Study. Steele, VR., Maxwell, AM., Ross, TJ., et al.[2020]

Intermittent theta-burst stimulation (iTBS) significantly improved working memory accuracy, reaction time, and discrimination ability in 40 individuals with methamphetamine use disorder compared to sham treatment over 10 days.

The study also found that iTBS reduced resting-state delta power in the left prefrontal region, suggesting a potential biological mechanism linked to cognitive improvements.

Intermittent theta burst stimulation to the left dorsolateral prefrontal cortex improves working memory of subjects with methamphetamine use disorder. Zhang, Y., Ku, Y., Sun, J., et al.[2023]

Intermittent theta burst stimulation (iTBS) of the prefrontal cortex has shown effects on reducing cocaine craving and consumption that are comparable to traditional high-frequency rTMS (15 Hz) in a study of 25 treatment-seeking cocaine addicts.

Both iTBS and 15 Hz rTMS demonstrated similar safety and tolerability profiles, with low dropout rates, suggesting that iTBS could be a more efficient treatment option due to its shorter duration (3 minutes) compared to the 15-minute standard protocol.

In a study involving 12 nicotine-dependent individuals, theta burst stimulation (TBS) applied to the right inferior frontal gyrus (r.IFG) significantly improved inhibitory control during tasks requiring self-control, indicating its potential as a treatment for nicotine addiction.

The study found that excitatory TBS (iTBS) enhanced inhibitory control, while inhibitory TBS (cTBS) impaired it, suggesting that non-invasive brain stimulation can modulate cognitive functions related to substance use disorders.

Intermittent theta burst stimulation (iTBS) over the left DLPFC and continuous theta burst stimulation (cTBS) over the right DLPFC significantly reduced cue-induced craving in abstinent methamphetamine-dependent subjects, indicating their potential efficacy as treatments for addiction.

The study involved 83 participants and showed that while iTBS had higher self-reported adverse effects initially, both stimulation methods were feasible and tolerable, suggesting a promising approach to reduce craving with shorter treatment sessions.

Intermittent theta burst stimulation (iTBS) and conventional 10 Hz repetitive transcranial magnetic stimulation (rTMS) showed similar effectiveness in reducing drug cravings and improving withdrawal symptoms in 20 male patients with methamphetamine use disorder (MAUD) after 12 treatments.

Both treatment methods were effective, suggesting that iTBS could be a viable alternative to 10 Hz rTMS, potentially enhancing the accessibility and cost-effectiveness of treatment for MAUD, although further large-scale studies are needed to confirm these findings.
