August 29, 2026 updated by: Cory Weissman, University of California, San Diego

Psilocybin-Assisted Therapy for Physician Well-Being and Burnout: Feasibility, Safety, Clinical Effectiveness and Biomarkers of Response [PAT-B (Psilocybin-Assisted Therapy for Physician Well-Being and Burnout)]

Through an open-label study involving a small group of UCSD physicians experiencing burnout, the investigators will evaluate the feasibility, safety, and preliminary effectiveness of PAT to reduce burnout symptoms.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Physician burnout is a critical issue. Research shows that physician burnout is increasing, that physicians suffer higher rates of burnout than the general population, and that physician burnout is associated with poor mental health outcomes.

Psilocybin is a naturally occurring alkaloid within certain fungi that elicits acute perceptual, cognitive, and emotional changes when ingested, due to action on neurotransmitter and neurocirculatory systems. The combination of psilocybin with psychological support, termed Psilocybin-Assisted Therapy (PAT), is a promising new mental health intervention shown to produce rapid and sustained improvements in psychological domains affected in burnout. PAT demonstrates preliminary efficacy as a treatment for depression and substance use disorders, is associated with brain changes measured with electroencephalography (EEG) and is a strong candidate treatment for physician burnout.

The primary aim is to assess whether incorporating biofeedback of interpersonal synchrony and individual biosignal biofeedback measures can enhance PAT outcomes. This will be determined by the superiority in the reduction of pre- and post-treatment burnout subscale scores of the biofeedback arm compared to the standard PAT arm. The secondary aim is to confirm the safety, tolerability, and efficacy of PAT to reduce burnout symptoms in physicians. In addition to these aims, exploratory analyses will examine neurophysiological and behavioral measures (e.g., EEG and multimodal synchrony) to evaluate their associations with clinical outcomes and identify potential biomarkers of response to psilocybin-assisted therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
