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.
