Description as written by the study sponsor.
The primary objective of this research study is to evaluate the effect of tirzepatide, relative to placebo, as an adjunct to BUP on retention, substance use, and sleep outcomes in individuals with OUD.
Treatments tested
- Tirzepatide also known as Mounjaro, Zepbound Drug
The tirzepatide pen is a pre-filled, disposable, injection device designed for subcutaneous administration. Each pen is pre-filled with a single dose of tirzepatide and is available in six doses: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg/0.5 mL. A UMC will administer the once-weekly SQ dose of tirzepatide. Consistent with tirzepatide's prescribing guidelines, participants will be initiated at a once-weekly SQ dose of 2.5 mg/week with a dose increase to 5mg/week at week 5. Consistent with tirzepatide's prescribing information, once the participant has received 5 mg/week for 4 weeks they are eligible for a dose increase if needed
- Placebo Other
Saline administered subcutaneously with a syringe will be used as the placebo for the trial. The placebo which will be administered by a study UMC. The process for deciding on "dose increases" will be the same for placebo and tirzepatide.
