BackgroundExtended-release naltrexone (XR-NTX) is an injectable monthly sustained-release mu opioid receptor antagonist, which blocks the typical effects of heroin and other opioid agonists. Use of XR-NTX among opioid dependent persons leaving jails and prisons is increasing despite scant high-quality evidence regarding XR-NTX's effectiveness at re-entry.MethodsThis 24-week, open-label randomized controlled trial examines the effectiveness of XR-NTX as opioid relapse prevention at release from jail (NÂ =Â 85) compared to enhanced treatment as usual (ETAU, NÂ =Â 85). A third, non-randomized, quasi-experimental naturalistic arm of participants who have newly initiated a jail-to-community methadone treatment program (MTP, NÂ =Â 85) allows for comparisons to a methadone standard-of-care.ResultsWe describe the rationale, design, and primary and secondary outcomes of the study. The primary outcome is an opioid relapse event; the primary contrast is a time-to-relapse comparison of XR-NTX and ETAU over a 24-week treatment phase. Secondary outcomes are rates of: (a) post-release opioid treatment participation, (b) opioid, alcohol, and cocaine use, (c) injection drug use and HIV sexual risk behaviors, (d) overdose (fatal and non-fatal) and all-cause mortality, and, (e) re-incarceration.ConclusionsXR-NTX is a potentially important, effective treatment and relapse prevention option for a large US population of persons with opioid use disorders leaving jails. This study will estimate XR-NTX's effectiveness relative to existing standards of care, including counseling-only treatment-as-usual and methadone maintenance.
