Adjunctive Effects of Psilocybin and a Formulation of Buprenorphine

Opioid Use Disorder Clinical Trial

Official title:
Phase I Study of the Safety and Adjunctive Effects of Psilocybin in Adults With Opioid Use Disorder Maintained on a Buprenorphine/Naloxone Formulation

Clinical Trial 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.

Clinical Trial 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 dosing, set, and setting, each participant will ingest 1 oral dose of psilocybin. All dosing sessions will be attended by 2 specially trained facilitators, in a dedicated Clinical Research Facility. After eight hours of observation in the dosing room, the participant will be kept overnight in the hospital Clinical Research Unit, and complete an integration session with a psychologist before discharge to home. Approximately 4 weeks after the first dose, the participant will receive a second oral dose of psilocybin, with the same length of observation. Participants who have been administered the first dose but decline to receive the second dose will remain evaluable. At study termination, their active study participation will end, but completion of the 28 day post-dose follow up will be requested. The primary endpoint is the assessment of the safety of concurrent administration of a buprenorphine-naloxone formulation and psilocybin as determined by physiological measures (ECG, respiratory rate, blood pressure, body temperature, and blood oxygen saturation) and validated clinical and self-report measures (Clinical Opiate Withdrawal Scale (COWS), Opioid Craving Scale (OCS), Timeline Follow-Back (TLFB)).
