The purpose of this research is to study the medical and safety effects of a single dose of an investigational drug called psilocybin compared to a placebo in participants with depression. Each participant will be randomized to receive either a one-time dose of psilocybin or a placebo.

Phase 2
Phase 2 clinical trials are the second step in a typical four-step drug approval process. During this process, the safety and usefulness of the investigational treatment is tested in larger groups of people as the drug moves through the phases. Phase 2 studies can involve up to several hundred volunteers.
50% Psilocybin
Chance of receiving investigational treatment under study.
50% Placebo (niacin)
Chance of receiving active placebo.
Each appointment is a little different and visit lengths vary, but most appointments last about 2 hours. At these visits, the following activities may occur:
Visit lengths are approximate and events are summarized. You can learn about the exact timing and events after you indicate an interest in the clinical trial.
You may qualify for this study if you meet the criteria listed below. You can learn if you qualify after you indicate an interest in the clinical trial.
Researchers in 9 planned locations across the U.S. are looking for volunteers for this clinical trial. New locations may be added in the future. You can learn more about the study locations after you indicate an interest in the clinical trial.
Because of the number of visits required, and for safety reasons, participants should live within approximately 2 hours of the study site.
