Optimizing Retention, Duration and Discontinuation Strategies for Opioid Use Disorder Pharmacotherapy (RDD)
NCT04464980 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04464980
The ClinicalTrials.gov registry entry for NCT04464980 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,516 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is NYU Langone Health, which has 1,204 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Opioid Use Disorder (OUD) appearing as the primary indexed condition, and to 5 interventions — of which XR-NTX is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04464980 reports 20 study locations spanning 14 distinct geographic areas — top geographies include Florida, Massachusetts, Oregon. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
