NCT06548490

Brief Summary

The goal of this clinical trial is to learn if semaglutide can reduce illicit opioid use in adults in outpatient treatment for opioid use disorder, and who are receiving either buprenorphine or methadone maintenance treatment. The main question it aims to answer is:

  • Does semaglutide increase the likelihood that participants will refrain from using illicit and nonprescribed opioids? The investigators will compare semaglutide to a placebo (a needle prick that contains no drug) to see if semaglutide works to reduce use of illicit and nonprescribed opioids. The participants will:
  • Take semaglutide or a placebo every week for 12 weeks
  • Visit the clinic every week for urine drug screening and pregnancy testing, vital signs, and to complete mental health and drug use questionnaires
  • Complete smartphone surveys sent at set times during the study

Outcome Measures

Primary Outcomes (12)

  • Number of participants being abstinent from illicit and nonprescribed opioids.

    Each week in the 12 week trial period will be rated as abstinent if both urine test and participants' report by Timeline FollowBack (TLFB) questionnaire are negative for illicit/non-prescribed opioids, or urine is negative and TLFB missing, or TLFB negative and urine missing; and not abstinent otherwise (either urine positive, or TLFB positive, or both are missing). For certain opioids (e.g., fentanyl), declining rates in urine will be considered negative for usage.
