First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests whether psilocybin therapy can reduce demoralization in adults with a life expectancy of two years or less. One hundred participants will receive either psilocybin or an active control (ketamine) in a triple-blind design. The goal is to see if this approach safely improves emotional well-being in palliative care.
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)
- What this could lead to
- If it works, this could offer a new way to ease deep distress and improve quality of life for people near the end of life.
- What could go wrong
- This is a mid-stage trial with only 100 people, so results may not apply to everyone. Psychedelic therapy can cause temporary confusion or emotional discomfort.
