Response to Relapse in Office-Based Opioid Treatment Trial

In a sample of individuals with co-occurring OUD and mental disorders, the investigators plan to test two medications for opioid use disorder (MOUD) treatment protocols that involve differing approaches to the use of opioids and other drugs during and after stabilization on MOUD - intensive vs. moderate treatment.The study is being conducted alongside the opening of a new clinical service funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) known as the Addiction and Behavioral Health Outpatient Recovery (ABOVE) program. The ABOVE Program is designed to treat patients with co-occurring opioid use disorder (OUD) and mental disorders with MOUD. Participants are individuals seeking treatment for co-occurring opioid use disorder (OUD) and mental disorders and are willing to receive MOUD treatment. Potential participants will be screened in the context of clinical care for opioid use disorder and mental disorders. If they are eligible for treatment in the ABOVE program, they will be asked to complete a baseline assessment, again for the purposes of clinical care. After completing the baseline clinical assessment, they will be asked to participate in this clinical trial, consented, then randomized. Treatment is delivered in the context of clinical care which involves delivery of MOUD and can involve psychiatric medications, and group and individual psychotherapy. Difference in treatment between the two randomization arms will only occur if a relapse to drug use occurs and will only involve two protocol-directed treatment responses to relapse.
