NCT ID NCT06206265

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

Summary

This small pilot study is testing whether psilocybin (the active ingredient in magic mushrooms) given alongside psychotherapy can safely help adults with irritable bowel syndrome (IBS). Fourteen participants will receive two doses of 25 mg of psilocybin in a controlled setting. The study uses a delayed-start design, meaning some people get treatment right away while others wait, to compare effects. The main focus is on safety, but researchers will also track changes in pain, stool habits, and mood.

Active substance

psilocybin (TRP-8802)

What this could lead to

If it works, this could point toward a new treatment option for irritable bowel syndrome that combines a psychedelic drug with talk therapy.

What could go wrong

This is a very small, early-phase pilot study with only 14 people. It is designed mainly to test safety, not effectiveness, so results may not apply broadly.
