Official title

Surmounting Withdrawal to Initiate Fast Treatment With Naltrexone: Improving the Real-World Effectiveness of Injection Naltrexone for Opioid Use Disorder (SWIFT)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study compares two methods of initiating treatment with extended-release naltrexone (XR-NTX) when implemented at community-based inpatient or residential programs. The primary goal of this hybrid effectiveness-implementation study is to determine whether the Rapid Method (5-7 day long) is non-inferior to a Standard Method (13-day long) on the primary effectiveness outcome of successful initiation of XR-NTX (receiving the first injection). Secondary objectives include comparing Rapid versus Standard method on: time from admission to first dose of XR-NTX and time to dropout, craving, withdrawal severity, retention, abstinence, and safety measures, as measured during the inpatient induction process and the first two months of post-induction XR-NTX maintenance. Other exploratory outcomes include predictors of initiation success, and economic analyses. The implementation goal is to operationalize an implementation facilitation strategy that will be used to train clinical sites on the XR-NTX initiation method, to capture fidelity to the rapid induction process, and to study barriers and facilitators to implementation and refine the implementation facilitation strategy accordingly.
