Saliva test may predict psychedelic therapy success for depression
NCT ID NCT07345858
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a hormone called oxytocin, measured in saliva during a psychedelic therapy session, can help predict how well people with major depression respond to treatment. Researchers will track changes in depression symptoms, flexibility in thinking, and anxiety in 80 adults. The goal is to better understand how psychedelic therapy works, not to test a new treatment.
