Summary

This study tests a biodegradable implant called OLANI that slowly releases naltrexone to block the effects of opioids for weeks. Researchers will enroll 250 adults with opioid use disorder who have already completed withdrawal. Participants will receive up to four implants over about a year to see if the treatment is safe and helps prevent relapse.

naltrexone implant (OLANI)
What this could lead to
If successful, this could provide a long-lasting, implant-based option to help people with opioid addiction avoid relapse and focus on recovery.
