ClinConnect Summary
This clinical trial is studying the effects of psilocybin-assisted therapy to see if it can help people with treatment-resistant depression, which means their depression has not improved with other treatments. The main goals are to find out if psilocybin, a natural substance found in certain mushrooms, combined with therapy can reduce depression symptoms and how long these benefits might last. Participants will go through a couple of preparation visits, receive psilocybin in one or two sessions, and then attend follow-up sessions for a year to share how they feel and complete surveys about their experiences.
To join the trial, participants should be between 18 and 75 years old, have a diagnosis of major depressive disorder, and have not found relief from at least two different depression medications. They should be in good health, be able to take oral medications, and have someone to support them after the treatment sessions. It's important to know that certain conditions, like a history of severe mental illness or substance abuse, may prevent someone from participating. This trial is currently looking for volunteers, and all participants will have a chance to contribute to finding new ways to treat depression.
