Testing a new antibody treatment for methamphetamine use disorder

OUTLAST - A First Multiple-Dose Efficacy Study of IXT-m200, an anti-METH Monoclonal Antibody, in Patients with METH Use Disorder

NIH-funded research Intervexion Therapeutics, LLC · NIH-10686245

This study is testing a new treatment called IXT-m200 to see if it can help people with methamphetamine use disorder stay off meth and reduce their chances of relapsing, and it's open to about 120 participants who will receive the treatment over six months.

What this research studies

This research investigates the efficacy of IXT-m200, an anti-methamphetamine monoclonal antibody, in treating individuals with methamphetamine use disorder (MUD). Participants will receive multiple doses of the antibody over six months, with the aim of reducing relapse rates to methamphetamine use. The study will involve approximately 120 participants, who will be monitored for safety and effectiveness as the treatment alters how methamphetamine is processed in the body. The research seeks to provide a new therapeutic option for a condition that currently lacks approved medications.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults diagnosed with methamphetamine use disorder who are seeking treatment.

Not a fit: Patients who do not have a diagnosis of methamphetamine use disorder or those who are not seeking treatment may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a novel treatment option for individuals struggling with methamphetamine use disorder.

How similar studies have performed: Previous studies have shown that single doses of IXT-m200 are safe, but this is the first multiple-dose study specifically targeting methamphetamine use disorder.
