Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates whether psilocybin therapy helps patients cope with chronic low back pain more effectively. Patients may be recruited at Stanford and University of California San Francisco (UCSF), study procedures will occur at UCSF. Each participant will receive a dose of psilocybin with possibly one or more other drugs. Participants will undergo two preparation sessions, a dosing session, three integration sessions to discuss their psilocybin experience, and several follow up sessions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic pain is associated with higher levels of pain-related distress, depression, emotional dysfunction, helplessness, hopelessness, and suicidality. Psilocybin is a psychoactive drug that may be well-suited to easing the psychological and emotional symptoms of distress associated with chronic pain. Previous studies testing psilocybin therapy have shown improvements on multiple behavioral and psychiatric outcomes, but it is unknown whether psilocybin therapy similarly enables patients to cope with chronic pain more effectively. The investigators will determine whether psilocybin therapy improves patients' ability to cope with chronic low back pain. If psilocybin therapy is an effective treatment in this population, its use could be incorporated into interventions for chronic low back pain and other psychological conditions.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

All patients will receive a dose of psilocybin between 1-30 mg, and one of the following: placebo, zolpidem, modafinial, or zolpidem and modafinil. All patients will receive two psilocybin preparation sessions , a single dose of psilocybin within a therapeutic environment (6-8 hours), three integration sessions and two follow up visits. All drugs will be orally administered during the dosing session. The study procedures will follow best practices for administering psilocybin in clinical trials.

Participants Caregivers Investigators Outcome Assessors
This trial is testing various doses of psilocybin in combination with add-on medications. Participants, study staff and clinical assessors will be blinded to individual treatment conditions until study close-out. The clinician administered instruments will be administered by different clinical study staff than the facilitators who provide the preparation, psilocybin therapy, and integration sessions.
