NCT ID NCT06731621

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage study tests whether psilocybin (the active ingredient in magic mushrooms) combined with talk therapy can safely help autistic adults with depression that hasn't improved with other treatments. Twenty participants will receive two doses of psilocybin along with about 20 hours of therapy. Researchers will also use brain scans to explore how the treatment might work.

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 with talk therapy
What this could lead to
If it works, this could point toward a new treatment option for depression in autistic adults who haven't responded to standard therapies.
What could go wrong
This is a very early, small pilot study with only 20 participants and no placebo group, so results may not apply broadly. Psychedelic drugs can cause intense psychological effects and side effects like anxiety or nausea.
