ClinConnect Summary

This clinical trial is studying how well psilocybin, a compound found in certain mushrooms, combined with therapy, can help adults who struggle with Alcohol Use Disorder (AUD). The main goals are to find out if this treatment can help reduce drinking more effectively than a placebo (a dummy treatment) along with therapy, and to ensure that it is safe for participants. People who take part in this study will attend 13 visits, participate in therapy sessions, and have two treatment sessions where they will either receive psilocybin or a placebo. Throughout the trial, they will keep track of their daily alcohol consumption.

To be eligible for this trial, participants should have a moderate to severe alcohol use problem and want to cut back or stop drinking. They need to be generally healthy and pass certain health checks. However, those with specific psychiatric disorders or a history of hallucinogen use disorder will not be allowed to participate. This trial is currently active but not recruiting new participants, and it welcomes individuals aged 18 to 65, regardless of gender. If you or a loved one is interested in the study or wants to learn more, it’s best to consult a healthcare professional.
