Can a diabetes and Weight-Loss drug help people quit meth?
NCT ID NCT07825857
First seen Sep 17, 2026 · Last updated Sep 21, 2026 · Updated 2 times
Summary
Researchers at UT Southwestern Medical Center are testing whether tirzepatide, a drug approved for diabetes and weight loss, can help people with moderate to severe methamphetamine use disorder reduce or stop using the drug. The trial enrolls 228 adults aged 18 to 65 who are overweight or obese and want to cut down on meth. Participants receive weekly injections of either tirzepatide or a saline placebo for 26 weeks, and researchers track urine drug screens, craving scores, and whether people stay in treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tirzepatide, a once-weekly injectable drug also known as Zepbound or Mounjaro
- What this could lead to
- If it works, this could point toward the first medication option for methamphetamine use disorder, a condition with no approved drug treatments.
- What could go wrong
- This is a phase 2 trial, so even positive results would need larger studies before becoming a standard treatment. Tirzepatide can cause nausea, vomiting, and other digestive side effects, and some participants may stop treatment early.
