Study Summary

This phase I/II trial tests the safety and side effects of psilocybin in combination with therapy for the treatment of patients with metastatic cancer and symptoms of anxiety and/or depression. Psilocybin is a substance being studied in conjunction with therapy for the treatment of anxiety and depression in patients with cancer. In this study, the psilocybin being used is derived from the mushroom psilocybe cubensis using a patented process that results in a pharmaceutical grade version of psilocybin. Psilocybin acts by activating serotonin receptors on brain cells which can change perceptions and patterns of thinking in ways that may decrease anxiety.

Primary Outcome

Defined as the occurrence of participant distress among study participants in the small group during the psilocybin administration session on Day 0 that requires 1:1 facilitator attention that cannot be met by the 4-person facilitation team. The size of small groups of different sizes will vary over the course of the study. Descriptive statistics will be used to analyze and will be tabulated on Day 0 after each group intervention. Backup facilitators will be available when this occurs.
