Brief Summary
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.

Study Arms (1)
Psilocybin Microdosing
EXPERIMENTALParticipants will receive a 4-week psilocybin microdosing intervention (1-3mg/day, Monday-Friday for up to 4 weeks; start at 1mg with opportunity to increase dose each week)
Interventions
Phase 1 (week 1): all enrolled participants will take a single 1mg oral dose of psilocybin once per day on Monday and Thursday. If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 2 for week 2. Phase 2: The participant will take a single 1mg oral dose of psilocybin once per day for 5 consecutive days (Monday to Friday). If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 3 for week 3. Phase 3: The participant will take two 1mg oral doses (2mg total) of psilocybin once per day for 5 consecutive days (Monday to Friday). If no adverse events are reported at any point during the week (Mon-Fri), the participant will continue to Phase 4 for week 4. Phase 4 (maximum allowable dose): The participant will take three 1mg oral doses (3mg total) of psilocybin once per day for 5 consecutive days (Monday to Friday).
