What is the purpose of this trial?

This trial aims to explore how Transcranial Magnetic Stimulation (TMS) might assist individuals with stimulant use disorder (StUD). Researchers will test various TMS applications to determine which most effectively influences brain and behavior responses. They seek adults who have been in recovery from stimulant use for at least two weeks and are currently in treatment. Participants must not have brain injuries or certain medical devices that could interfere with the study. This research aims to discover improved methods for supporting recovery from stimulant addiction. As a Phase 1 trial, the focus is on understanding how the treatment works in people, offering participants the opportunity to be among the first to experience this innovative approach.

Will I have to stop taking my current medications?

The trial protocol does not specify whether participants must stop taking their current medications. However, participants must be abstinent from substance use (other than caffeine or nicotine) for at least 2 weeks before joining the study.

What prior data suggests that transcranial magnetic stimulation is safe for treating stimulant use disorder?

Research has shown that Transcranial Magnetic Stimulation (TMS) is generally safe and well-tolerated for individuals with substance use disorders. Most side effects are mild and similar to those experienced by others undergoing TMS. The primary concern is a very low risk of seizures, occurring in less than 1% of cases. However, factors such as alcohol use or lack of sleep may increase this risk. Despite this, TMS remains widely used and considered safe for many, including those with stimulant use disorders. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment?

Researchers are excited about transcranial magnetic stimulation (TMS) for stimulant use disorder because it offers a unique, non-invasive approach to treatment. Unlike traditional methods that often rely on counseling or medications, TMS uses magnetic fields to stimulate specific brain areas, potentially reducing cravings and withdrawal symptoms. This technique is being optimized in different ways, like closed-loop and open-loop systems, each designed to deliver tailored brain stimulation. By directly targeting brain circuits involved in addiction, TMS holds promise for quicker and more effective relief compared to existing treatments.

What evidence suggests that transcranial magnetic stimulation is effective for stimulant use disorder?

Research has shown that transcranial magnetic stimulation (TMS) holds promise for treating stimulant use disorder. This trial will explore various TMS approaches, including closed-loop-peak, closed-loop-trough, and open-loop methods. Studies have found that repetitive TMS (rTMS) can significantly reduce cravings for stimulants, with positive effects lasting at least 30 days after treatment in some cases. Another study found that TMS helped individuals reduce cocaine use over an extended period. These findings suggest that TMS could aid in reducing stimulant use and managing cravings more effectively. ^{6 7 8 9 10}

Published Research Related to This Trial

Transcranial magnetic stimulation (TMS) is emerging as a promising noninvasive treatment for substance dependence, potentially filling a gap in addiction therapies, as it is already FDA-approved for depression.

Repetitive TMS (rTMS) has shown potential in altering behavior and brain activity related to addiction, and future studies may benefit from combining rTMS with medications and cognitive behavioral therapies to enhance treatment outcomes.

Modulating Neural Circuits with Transcranial Magnetic Stimulation: Implications for Addiction Treatment Development. Hanlon, CA., Dowdle, LT., Henderson, JS.[2019]

Non-invasive brain stimulation (NIBS), including transcranial electrical stimulation (tES) and transcranial magnetic stimulation (TMS), shows promise as a treatment for substance-use disorders (SUDs), supported by preclinical research linking brain circuits to drug behavior.

The paper emphasizes the need for standardized methods and outcome measures in NIBS research for SUDs, aiming to improve the translation of neuroscience findings into effective clinical treatments.

Transcranial magnetic stimulation (TMS) has been explored in 19 studies involving 316 adults for its potential to reduce drug cravings and use, particularly targeting the dorsolateral prefrontal cortex with high-frequency pulses.

While some studies showed promising results, such as decreased smoking and cocaine use, the treatment is still experimental, and the exact mechanisms and optimal parameters for rTMS in addiction treatment remain unclear.

High-frequency repetitive transcranial magnetic stimulation (rTMS) significantly reduced drug craving in patients with methamphetamine use disorder, as evidenced by lower Visual Analog Scale (VAS) scores compared to the sham group.

The 10-Hz rTMS group also showed improved decision-making abilities on the Iowa Game Test (IGT), particularly in later blocks, indicating that rTMS may enhance cognitive function in addition to reducing cravings.

Nonsmokers were significantly more likely to remain eligible for an rTMS study and complete it compared to smokers, with eligibility rates of 84.2% versus 57.4% and completion rates of 87.5% versus 59.3%.

The study suggests that smokers may require more careful screening for drug use and brain abnormalities before receiving rTMS treatment, highlighting a potential need for increased awareness of incidental MRI findings in this group.
