Johns Hopkins University
Summary
This is a 4-week, randomized-controlled trial of suvorexant vs placebo in persons with opioid use disorder who have recent fentanyl exposure. Participants will first undergo a 5-day residential phase wherein participants are stabilized on sublingual buprenorphine/naloxone, followed by a 3-week outpatient phase wherein participants are maintained on sublingual buprenorphine/naloxone and transitioned to extended-release buprenorphine).

The study will consist of a brief (5 day) residential phase and 3-week outpatient phase. During the residential phase, all participants will be briefly maintained on a short acting opioid prior to induction onto sublingual (SL) buprenorphine (using either the buprenorphine or buprenorphine/na…
