Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial tests whether a non-invasive brain stimulation technique, called transcranial temporal interference stimulation, can reduce drug cravings in people with methamphetamine use disorder. The stimulation targets the nucleus accumbens, a brain region involved in reward and addiction, and is delivered in real time when a patient shows a cue-induced craving response. Fifty adults with methamphetamine use disorder will receive either active stimulation or a sham procedure over five days. Researchers will measure changes in craving scores and drug-related thoughts to see if the approach helps improve control over drug use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Closed-loop transcranial temporal interference stimulation (tTIS) targeting the nucleus accumbens
What this could lead to
If it works, this could offer a non-invasive brain stimulation treatment to curb drug craving and support recovery in people with methamphetamine use disorder.
What could go wrong
This is an early, small trial with 50 participants, so results may not hold up in larger studies. The stimulation is experimental, and its effects on craving and brain function are still uncertain.
