Can psilocybin boost the power of talk therapy for borderline personality disorder?
NCT ID NCT07833761
First seen Sep 22, 2026 · Last updated Sep 23, 2026 · Updated 1 time
Summary
Researchers at the University of Minnesota are testing whether psilocybin-assisted therapy can be safely added to dialectical behavior therapy (DBT) for adults with borderline personality disorder. Participants stay in their usual DBT program while receiving preparation sessions, two supervised 25 mg doses of psilocybin, and integration therapy. The trial primarily tracks safety and tolerability, including side effects, suicidal ideation, and how many participants complete the study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- psilocybin, a psychedelic drug, given alongside dialectical behavior therapy
- What this could lead to
- If it proves safe and tolerable, this could point toward a new way to combine psychedelic-assisted therapy with an established talk therapy for borderline personality disorder.
- What could go wrong
- This is a very small, early-stage trial with no control group, so it cannot show whether the combination works better than DBT alone. Psilocybin can cause intense or distressing experiences, and people with borderline personality disorder may be especially vulnerable to emotional ups and downs during dosing.
