Neurobehavioral Mechanisms of Psilocybin-assisted Treatment for AUD

NCT06349083 · Status: RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 200

No results posted yet for this study

Summary

This is a double-blind, randomized, placebo-controlled Phase 2 mechanistic clinical trial designed to evaluate the therapeutic neural mechanisms of psilocybin in patients with alcohol use disorder (AUD), and to determine whether further studies are warranted to study the relationship of any such effects to clinical improvement in AUD symptoms. The primary aims are to evaluate the effects of psilocybin on AUD; measures will include 1) fMRI neural activation and functional connectivity, using a well-validated task to characterize neural and subjective response to negative affective and alcohol visual stimuli; 2) alcohol use data (self-report and blood biomarkers); and 3) self-report measures related the NE, IS, and EF domains.

Conditions

Interventions

DRUG

Psilocybin

One 25 mg capsule and one 5 mg capsule (30 mg total) administered once orally

OTHER

Inactive Placebo

Two matching placebo capsules administered once orally

BEHAVIORAL

Supportive therapy sessions

Participants will receive four supportive therapy sessions of manual-based treatment from two Center for Psychedelic Medicine (CPM) clinicians. The lead clinician will be a licensed physician, clinical psychologist, or nurse practitioner who will be primarily responsible for the content of the intervention. The second therapist will have at least a master's degree or be pursuing a master's or doctoral degree in a related clinical field.
