Psilocybin-Assisted Psychotherapy for Improving Depression and/or Anxiety in Patients Receiving Maintenance Therapy for Advanced Cancers, TRIP Trial

Trial Status: active

This phase II trial tests the safety and side effects of psilocybin in combination with psychotherapy compared to placebo (niacin [a B vitamin]) in combination with psychotherapy for improving depression and/or anxiety in patients who are on maintenance therapy for cancers that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Psilocybin is a substance being studied for the treatment of anxiety or depression in patients with cancer. It is taken from the mushroom psilocybe mexicana. Psilocybin acts on the brain to cause hallucinations (sights, sounds, smells, tastes, or touches that a person believes to be real but are not real). Niacin is a nutrient in the vitamin B complex that the body needs in small amounts to function and stay healthy. Niacin helps some enzymes work properly and helps skin, nerves, and the digestive tract stay healthy. Psychotherapy is used as a therapeutic treatment for mental, emotional, personality, and behavioral disorders with methods such as discussion, listening, and counseling. Combining psilocybin with psychotherapy may help to improve depression and/or anxiety in patients with advanced cancers.
