 This study is part of the NIDA Studies of Medication for Addiction Treatment in Correctional Settings SOMATICS U01 Collaborative. Our distinct NIH-funded study at Friends Research Institute has been aligned with two other jail-based opioid treatment studies conducted by researchers at New York University NYU and at University of California Los Angeles UCLA. SOMATICS seeks to harmonize assessments and interventions across the three research centers RCs and the three independent studies in order to leverage power, sample size, and increase the generalizability of findings. Each of the RCs in the SOMATICS cooperative will conduct their own individual trial, sharing one study arm with another RC, and several core assessments across all sites. The SOMATICS collaborative will have a common Statistical Analysis Plan and Data and Safety Monitoring Plan DSMP including a single DSMB. The collaborative primary and secondary outcomes across all sites are listed below:
