Summary

This completed study looked at 12 people with opioid use disorder who had been stable on SUBLOCADE injections for at least 9 months. Researchers wanted to see if they could successfully stop the medication without relapsing or restarting long-term treatment. The goal was to understand the withdrawal experience and how well people manage after stopping.

What this could mean

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

Active substance
SUBLOCADE (buprenorphine extended-release injection)
What this could lead to
If successful, this could help doctors and patients understand the best way to safely stop long-term opioid addiction medication without relapse.
What could go wrong
This is a very small, completed observational study with only 12 participants, so results may not apply to everyone. It does not test a new treatment.
