PHASE1

Psilocybin Effects on Healthy Aging Biomarkers and Purpose in Life

Sponsor: Charles Raison

View on ClinicalTrials.gov

Summary

The LONG-LIFE study is a randomized Phase I, dose-ranging trial designed to evaluate whether psilocybin impacts aging-related biomarkers, cognitive function, and purpose/meaning in life in medically stable older adults. Up to 50 participants will be enrolled aged 60-80 who will be randomized with equal allocation to one of four intervention groups: (1) receipt of one 25 mg dose of psilocybin; (2) receipt of two 25 mg doses of psilocybin separated by four weeks; (3) receipt of three 25 mg doses, with each dose separated by four weeks; or (4) wait-list comparator condition that does not receive psilocybin. Biomarkers of aging, cognitive performance, and behavioral measures will be assessed at baseline and longitudinally over a 12-month follow-up period. The primary endpoint occurs at the Week 16 visit. Participants randomized to the wait-list condition will be offered a single 25 mg dose of psilocybin following conclusion of the 12-month follow-up period. Findings from this Phase I study will inform dose selection for a Phase II study should results indicate a potential impact of psilocybin on relevant study endpoints.
