Clinical Trial Summary

This study is designed to elucidate the role of the orexin neurotransmitter system in sleep disturbance and circadian rhythms of stress that might in turn influence relapse behaviors in persons on medication-assisted treatments (MAT) who are in early recovery from opioid use disorder (OUD). Briefly, the study will enroll recently abstinent OUD patients (N=200) maintained on either extended-release naltrexone (XR-NTX), buprenorphine, or methadone. Within each MAT group, participants will be randomized to either suvorexant or placebo. The study is expected to have a 20% treatment attrition rate which will result in N=160 completers in the entire study. Patients will be recruited from and treated at Ashley Addiction Treatment, Addiction Treatment Services at Johns Hopkins Bayview Medical Center, Man Alive, or community providers.
