Summary

This trial will compare the effectiveness of two types of medication-assisted treatment for opioid use disorder among individuals in county jails in Maryland.

Who is the study for?
This trial is for adult male and female inmates in Maryland with moderate to severe opioid use disorder, or those treated for it within the last year. They must be due for release within 120 days, plan to live locally post-release, and pass a medical evaluation. Exclusions include severe liver issues, certain heart diseases or conditions that affect heart rhythm, untreated serious mental health disorders, pregnancy or breastfeeding women, extreme obesity (BMI > 40), and current enrollment in other medication-assisted treatments.
What is being tested?
The study compares two extended-release medications given to individuals leaving jail: XR-B (buprenorphine) versus XR-NTX (naltrexone). Participants will receive one treatment while incarcerated followed by six monthly injections after release. The assignment of either XR-B or XR-NTX is random within gender groups.
What are the potential side effects?
Potential side effects of both medications can include nausea, headache, dizziness, fatigue, injection site reactions and possible liver function changes. Side effects vary from person to person.
