๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This study is a phase 2 single-site, double-blind, placebo-controlled, randomized clinical trial with an open-label extension phase to examine the safety of psilocybin (25 mg) combined with psychological support (Psi-PS) for treatment of approximately 40 military veterans and first responders (ages 21-65) with co-occurring alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD). Psychological support is defined as providing safety, reassurance, active listening, and empathetic presence during the drug administration session in a nondirective manner. We hypothesize that Psi-PS may provide a safe treatment for participants. The primary objective of study is to characterize the safety of psilocybin combined with psychological support (Psi-PS) for individuals with co-occurring alcohol use disorder (AUD) and PTSD.
