Phase I Study of the Safety and Adjunctive Effects of Psilocybin in Adults With Opioid Use Disorder Maintained on a Buprenorphine/Naloxone Formulation
University of Wisconsin, Madison
Summary
Primary Aim: In participants with OUD, to characterize adverse events associated with adding two psilocybin doses to a stable buprenorphine-naloxone formulation. Secondary Aim: To evaluate the effect of psilocybin treatment on the effectiveness of a buprenorphine-naloxone maintenance therapy. Secondary Aim: To evaluate the effect of concurrent buprenorphine-naloxone use on the effects of psilocybin therapy. Descriptive Aim: To describe any changes in self-efficacy, quality of life, pain.
Description
The primary objective of this clinical trial is to determine the safety of psilocybin in adult patients with opioid use disorder concurrently taking buprenorphine-naloxone. Eligible participants will be adults with active opioid use disorder (OUD) who are willing to begin and maintain a daily dose of buprenorphine-naloxone throughout study participation. Initiation, stabilization, and maintenance of buprenorphine-naloxone will be overseen by a qualified study medical provider. After psychological screening and at least 6 hours of preparatory counseling and preparation for the psilocybin dosin…
