Study Summary

Psilocybin is a naturally occurring psychedelic compound produced by more than 200 species of mushrooms, collectively known as psilocybin mushrooms. Psilocybin (4-phosphoroyloxy-N,N-dimethyltryptamine) is a hallucinogenic tryptamine that was first isolated from Psilocybe mushrooms in 1957. The objective of this Phase I clinical trial is to determine the pharmacokinetics of oral doses of psilocybin in normal, healthy adults. The study is performed in support of Phase II and Phase III studies of psilocybin for the treatment of refractory anxiety associated with incurable cancer, as well as other possible indications. Psilocybin is at present not an FDA-approved drug.

Primary Outcome

Determine the AUC of psilocin in plasma following single doses of 0.3, 0.45, and 0.6 mg/lg psilocybin, the precursor to psilocin.
