About this trial
The goal of this multi-centre phase I/II open-label, single-arm study is to determine the safety, feasibility, therapeutic dose, and preliminary efficacy of psilocybin microdosing to treat psychological distress among patients with advanced illness. Forty patients will receive psilocybin drug product (1-3mg per day, Mon-Fri) for 4 weeks to be administered via oral capsules by the participant. Feasibility (recruitment rate, rate of intervention and follow-up completion), safety (rate of adverse events), dosing, and preliminary efficacy (depression, anxiety, overall well-being, and global impression of change) will be measured.
