Official title
NIDA-CTN-0100: Optimizing Retention, Duration and Discontinuation Strategies for Opioid Use Disorder Pharmacotherapy (RDD)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a two phase study investigating combinations of pharmacological and behavioral interventions to optimize the treatment of Opioid Use Disorder (OUD). The Retention Phase will assess strategies for improving retention on buprenorphine (BUP) and extended-release injectable naltrexone (XR-NTX). The Discontinuation Phase will assess which approaches are most likely to lead to long-term success (absence of relapse), and what characteristics of participants distinguish those who can safely discontinue Medications for Opioid Use Disorder (MOUD) from those who remain at risk of relapse and should not discontinue.
