Study Summary

This study will evaluate the effectiveness of a new pharmacological approach to increase efficacy of treatment with extended release naltrexone (XR-naltrexone) for individuals with opioid use disorder by combining it with buprenorphine-naloxone. This is a two arm, double-blind, placebo-controlled study to examine whether addition of buprenorphine-naloxone will improve treatment retention, reduce opioid craving, and improve mood over 24 weeks of treatment with extended release naltrexone (XR-naltrexone) administered every four weeks for a total of 6 injections. The NYSPI site, which provides study oversight (no direct participant involvement) is currently paused and has been paused since an institutional pause on human subjects research began in June, 2023. The U.S. Department of Health and Human Services (HHS) Office of Human Research Protections (OHRP) issued an FWA restriction on NYSPI research that also included a pause of human subjects research as of June 23, 2023.

Primary Outcome

Proportion of patients successfully retained to receive six consecutive XR-naltrexone injection.
