About this study

Official title: ADEPT: Augmenting DBT Effectiveness With Psilocybin-Assisted Therapy

ADEPT is an open-label proof-of-concept study evaluating the safety and tolerability of psilocybin-assisted therapy in conjunction with Dialectical Behavior Therapy for participants with borderline personality disorder.

Participants enrolled in the M Health Fairview Dialectical Behavior Therapy program will receive preparation therapy sessions, two supervised 25 mg psilocybin dosing sessions, integration therapy sessions, and a final follow-up visit. Participants will continue their usual DBT program during study participation.

The study will primarily assess safety and tolerability, including adverse events, treatment-emergent adverse events, serious adverse events, suicidal ideation, challenging psychedelic experiences, psilocybin-related side effects, study retention, therapy session attendance, and assessment completion.

Read the detailed description

ADEPT is an open-label proof-of-concept study designed to assess the safety and tolerability of combining psilocybin-assisted therapy with Dialectical Behavior Therapy in participants with borderline personality disorder.

The study will enroll up to 18 participants who have a confirmed DSM-5 diagnosis of borderline personality disorder and are enrolled in the M Health Fairview Dialectical Behavior Therapy program. Participants must have been enrolled in DBT for at least one month and must have consistent attendance in both group and individual therapy.

The study intervention includes two 25 mg doses of psilocybin administered during supervised dosing visits. Three preparation therapy visits will occur before the first dosing visit. The first dosing visit will be followed by three integration therapy visits. A second psilocybin dosing visit will occur approximately 21 days later, followed by three additional integration therapy visits. Participants will complete a final follow-up visit at week 18, approximately 12 weeks after the second dosing visit.

Participants will continue their usual DBT program while enrolled in the study. The M Health Fairview DBT program includes weekly individual therapy, group therapy skills development, and access to phone coaching.

The primary focus of the study is safety and tolerability. Participants will be monitored during and after dosing, and adverse events, treatment-emergent adverse events, serious adverse events, suicidal ideation, challenging experiences, and psychedelic-related side effects will be assessed. Secondary outcomes will evaluate changes in borderline personality disorder symptoms, emotion regulation, depressive symptoms, quality of life, treatment credibility and expectancy, mystical experience, and continued participation in DBT after psilocybin-assisted therapy.

A Phase 1 study testing Psilocybin and Psilocybin-Assisted Therapy With Dialectical Behavior Therapy in people with Borderline Personality Disorder and Borderline Personality Pathology, run by University of Minnesota at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 22 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Ziad Nahas, MD, MSCR (952-525-4505, znahas@umn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence, Severity, and Frequency of Adverse Events (time frame: Baseline through final study visit at week 18). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Sep 2026.
