NCT ID NCT05382091
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- 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.
- What could go wrong
- This is an early phase II study focused on safety, not yet proven effective. Side effects from the implant or procedure, and the possibility that it may not block opioids as expected, are key risks.
