Cancer-related anxiety and depression established evidence

Rapid and sustained symptom reduction following psilocybin treatment for anxiety and depression in patients with life-threatening cancer

Key finding

A single psilocybin dose produced immediate, substantial, and sustained reductions in cancer-related anxiety and depression, with antidepressant and anxiolytic effects persisting at 6.5 months in the majority of participants.

Institution
NYU Langone
Design
Randomized, double-blind, placebo-controlled crossover
Sample size
29 participants
Intervention
Single 0.3 mg/kg psilocybin vs. niacin active control, crossover
Year
2016
Condition
Cancer-related anxiety and depression
Limitations

Small sample; niacin is an imperfect blind; participants were carefully screened, limiting generalizability.

Published simultaneously with the Hopkins cancer trial, the NYU study independently reached strikingly similar conclusions. The convergence of two separate teams on the same finding is part of why the end-of-life evidence base is considered unusually robust.
