Glutide for Ending Methamphetamine (GEM) Study

This study, called GEM, is looking at whether a medication called Semaglutide (also known as Wegovy) can help treat methamphetamine use disorder. It's a two-part study. The first part is a small pilot study with 25 participants to see if Semaglutide is practical and acceptable, and if it shows early signs of working. The second part will be a larger study with 162 participants, comparing Semaglutide to a placebo (a sugar pill) to see how well it works. We'll be looking at things like how many people join the study, if they take their medication as planned, and changes in methamphetamine use after 12 weeks. You can join if you are between 18 and 65 years old and meet other study requirements. The current status of the study is unclear.

Study design
This study has two phases. The first is a small, open-label pilot study with 25 participants. The second is a larger, randomized-controlled trial with 162 participants, where some will receive Semaglutide and others a placebo, and neither you nor the researchers will know which you are receiving (blinded).
What's involved
If you join the pilot study, you will receive Wegovy for 12 weeks, with a follow-up visit at week 20. The second phase will be similar, but with randomization to Wegovy or placebo.
Compensation
Not stated in the trial record.
Follow-up
Participants in the pilot study will have a follow-up visit at week 20. The study will measure outcomes up to 20 months after the start of the study.

  • Ratio of eligible to enrolled participants14 months

    Feasibility of Wegovy for MeUD treatment: Feasibility will be determined by measuring the ratio of eligible to enrolled participants

  • Proportion of on-time injections20 months

    Acceptability of Wegovy for MeUD treatment: Acceptibility of the treatment will be determined by measuring the adherence to available study drug injections (proportion of on-time injections administered)

  • Past month methamphetamine use at baseline vs. week 1212 weeks

    Reduced methamphetamine use: Signs of reduced methamphetamine use by hair testing or self-report (timeline follow back) for the past four weeks, measured at baseline vs. week 12.

  • Rate of study-drug discontinuation12 weeks

    Safety of Wegovy for MeUD treatment: Safety will be determined by measuring the rate of study-drug discontinuation due to adverse events

  • Reduced methamphetamine use12 weeks

    Reduced methamphetamine use, measured by proportion achieving "response," defined as 3 out of the final 4 urines collected negative for methamphetamine.
