CURE Addiction Center of Excellence: Brain Mechanisms of Relapse and Recovery

• Status: Completed
• Trial end date: 2021-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The proposed project will use fMRI and specific probes of reward and inhibition as biomarkers predicting drug use during and after treatment in 72 subjects addicted to prescription opioids/medications. Subjects will be scanned before, during, and after 12 weeks of active medication. The brain fMRI measures will be correlated with the primary clinical outcome of drug use (by urine drug screen) during the treatment and follow-up phase.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: University of Pennsylvania
