Active Control
Placebo Group
Group I: Psilocybin 25 mgExperimental Treatment1 Intervention
During the Double-blind Period, participants randomized to receive Psilocybin 25 mg will receive a single dose administered orally as a capsule and taken with water, along with the "Set and Setting" (SaS) Protocol. The "Set and Setting" (SaS) Protocol includes preparatory meetings with two Facilitators prior to dosing, a 7-10 hour dosing session in a comfortable room under the supervision of the same two Facilitators, and 4 hours of post-dose integration sessions with Facilitators. During the dosing session, participants are encouraged to wear eyeshades and listen to a curated playlist on headphones.
Group II: Long-Term Follow-UpExperimental Treatment2 Interventions
After the initial 6-week Double-blind Period, all participants will proceed to a 1-year Follow-up Period. Participants will be followed via in-clinic visits and telephone visits during which clinic staff will assess changes in MDD symptom severity and safety measures including concomitant medications, adverse events (AEs), and suicidal ideation and behavior. Participants will also engage in group psychosocial support sessions, including psychoeducation, throughout this period. Participants may also be eligible to receive open-label re-administration(s) of Psilocybin 25 mg under the "Set and Setting" (SaS) Protocol if re-administration eligibility criteria are met.
Group III: Psilocybin 5 mgActive Control1 Intervention
During the Double-blind Period, participants randomized to receive Psilocybin 5 mg will receive a single dose administered orally as a capsule and taken with water, along with the "Set and Setting" (SaS) Protocol. The "Set and Setting" (SaS) Protocol includes preparatory meetings with two Facilitators prior to dosing, a 7-10 hour dosing session in a comfortable room under the supervision of the same two Facilitators, and 4 hours of post-dose integration sessions with Facilitators.
