Summary

This study tests whether starting a monthly extended-release buprenorphine injection (Sublocade) in jail helps people with opioid use disorder stay on treatment after release. Two hundred men entering jail with a daily buprenorphine prescription will be randomly assigned to either switch to the monthly shot or stay on daily pills. Researchers will track how many leave jail with at least 7 days of buprenorphine in their system and how many continue treatment in the community.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Extended-release buprenorphine (Sublocade injection)
What this could lead to
If successful, this could show that starting a monthly buprenorphine shot in jail helps more people continue their opioid use disorder treatment after release, reducing relapse and overdose risk.
What could go wrong
This is a single-site study with 200 men, so results may not apply to all populations. The intervention requires starting in jail, which may not be feasible everywhere. Risks include injection site reactions and potential for diversion.
