Summary

This trial is testing a new treatment for people trying to quit methamphetamine. It aims to see if the treatment can lower meth levels in the body and help with symptoms of meth addiction.

Who is the study for?
Adults seeking treatment for methamphetamine use disorder, with recent positive drug tests. Participants must be willing to follow study rules and attend all appointments, use approved birth control methods, have smartphone access for the study app, and meet DSM-5 criteria for Substance Use Disorder related to methamphetamine.
What is being tested?
The trial is testing IXT-m200's safety and effectiveness in reducing relapse rates compared to a placebo in individuals with Meth Use Disorder. It involves monthly IV doses and measures the reduction of stimulant-positive saliva samples following an initial relapse.
What are the potential side effects?
Potential side effects are not specified but may include reactions similar to other monoclonal antibodies such as infusion-related reactions, allergic responses or sensitivities due to ingredients in IXT-m200.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for methamphetamine abuse, such as IXT-m200, aim to reduce the effects or cravings associated with methamphetamine use. These treatments often work by targeting the brain's reward system, particularly the dopamine pathways, which are heavily impacted by methamphetamine. For instance, medications like varenicline act as selective nicotinic acetylcholine receptor agonists, which can modulate dopamine release and reduce cravings. Other treatments may include cognitive-behavioral therapy (CBT) to help patients modify behaviors and thoughts related to substance use. These mechanisms are crucial for patients as they help to mitigate the intense cravings and withdrawal symptoms, making it easier to maintain abstinence and improve overall treatment outcomes.
