Office-based Methadone Versus Buprenorphine to Address Retention in Medication for Opioid Use Disorder Treatment.
brief summary
The purpose of this clinical trial is to compare the effectiveness of office-based methadone with pharmacy administration and/or dispensing to office-based buprenorphine for the treatment of opioid use disorder. This study will also examine factors influencing the implementation of office-based methadone.
detailed description
This study is a randomized, pragmatic hybrid type 1 effectiveness/implementation multisite (approximately 6 sites) trial to determine whether office-based methadone with pharmacy administration and/or dispensing or buprenorphine (BUP) results in greater treatment retention in approximately 600 patients with opioid use disorder (OUD). This trial will also identify implementation barriers, facilitators and acceptability at the patient, provider and health-systems level for office-based methadone with pharmacy administration and/or dispensing.
An ancillary sub-study was added to this trial in January of 2026. A sub-set of current participants that were receiving office based methadone as of day 168 of the parent study will continue to be followed for other pre-specified outcomes.
