Brief Summary

The goal of this randomized placebo controlled trial is to compare the antidepressant effect of a single oral dose of psilocybin 25 mg compared to 1 mg in 100 patients with cancer related major depressive disorder. The main question it aims to answer is:

≥10), >1 month after cancer diagnosis, with at least 12 months of life expectancy, willingness to abstain from other psychotherapeutic or antidepressant treatments during the study (wash out time 5 half-lives).
