What is 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.
It is , overseen by an independent and licensed medical staff.

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.

What you need to know before you apply
What is this study testing?+
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.
Is it safe? Who makes sure of that?+
This is a mid-stage study (Phase 2), looking at safety and whether the treatment works. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
Do I have to stop taking my current medications?+
It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.
Does it cost anything? Will I be paid?+
The study treatment and study-related visits are provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
