This Phase II, single-group trial (n=10) will evaluate the safety, acceptability, and efficacy of psilocybin-assisted psychotherapy in patients with non-small cell lung cancer (NSCLC) who also suffer from major depressive disorder. The study aims to determine the impact of psilocybin on depression symptoms, quality of life, cancer-related stress, and existential distress, given the high prevalence of mood disorders in lung cancer patients. Participants will undergo two preparation therapy sessions before receiving oral psilocybin on day 21, followed by an 8-10 hour dosing therapy session. Post-dosing, two additional therapy sessions will occur on days 22 and 28. Throughout the study, blood and urine samples will be collected, and participants will be monitored for adverse events and suicidal ideation at various intervals. The trial will follow participants for 4 and 12 weeks after treatment completion to assess long-term effects.
This phase II trial tests the safety and side effects of psilocybin in combination with therapy for the treatment of major depressive disorder in patients with non-small cell lung cancer. A cancer diagnosis is life-changing, resulting in significant levels of psychological symptoms, including a combination of depression, anxiety, stress, including feelings of existential distress (i.e., loss of meaning, demoralization, despair). Among all cancer patients, those diagnosed with lung cancer have the highest prevalence of mood disorders, such as depression (up to 40%) leading to profound deterioration in quality of life, prolonged hospital stays, poorer treatment adherence, decreased survival rates, and high rates of suicide (5- and 3-times higher than the general population and other cancer patients, respectively). Psilocybin is substance being studied in the treatment of anxiety or depression in patients with advanced 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). Psilocybin in combination with therapy may be safe and effective in treating major depressive disorder in patients with non-small cell lung cancer.
Patients participate in two preparation therapy sessions over 4 hours each on days 7 and 14, then patients receive psilocybin PO on day 21 and participate in a single dosing therapy session for over 8-10 hours on study. Patients also complete two post-dosing therapy sessions over 2 hours each on days 22 and 28 on study. Patients additionally undergo blood and urine sample collection throughout the study.
