About this study

This phase II trial tests the safety, side effects and how well group retreat psilocybin therapy works for the treatment of anxiety and depression in patients with solid tumors that have spread from where they first started (primary site) to other places in the body (metastatic) or with hematologic cancers for which no treatment is currently available (incurable). For patients with metastatic, incurable cancer, unrelieved anxiety and existential distress can cause profound suffering. Psilocybin therapy can relieve anxiety and existential distress by disrupting patterns of thinking that contribute to anxiety and depression. Psilocybin is a substance being studied in the treatment of anxiety or depression in patients with cancer. In this study, a pharmaceutical grade of psilocybin will be used that has been approved by the FDA for research, provided by Filament Health. Psilocybin acts on the brain by resetting the brain's activity and increasing connections between brain regions, particularly those involved in mood regulation and self-perception. In this study psilocybin is combined with structured discussions and reflections that enable patients to have new insights about their situation. In a prior study, group retreat psilocybin therapy was proven to be safe and this study tests a refined dosing regimen for symptoms of anxiety and depression in patients with metastatic solid tumors or incurable hematologic malignancies.
