NIDA CTN-0051: Extended-Release Naltrexone vs. Buprenorphine for Opioid Treatment (X:BOT)

This study will assess the comparative effectiveness of extended release injectable naltrexone (XR-NTX, Vivitrol^®) versus buprenorphine-naloxone (BUP-NX, Suboxone^®) as pharmacotherapeutic aids to recovery amongst treatment-seeking participants who have completed detoxification and achieved short term abstinence. The primary objective is to compare the effectiveness of XR-NTX versus BUP-NX in promoting the joint outcome of sustained retention in treatment and abstinence after an index admission for opioid dependence. A rescue protocol will enable the study to address additional questions regarding the sequencing of treatments.
