Double-blind, randomised, placebo-controlled single-ascending subcutaneous dose PK and safety study in healthy volunteers (n≈48; cohorts of 8, 6 active + 2 placebo) of FT-104 HCl (psilocybin formulation).
Phase I, cohort-based, single-ascending dose study of subcutaneous FT-104 HCl in healthy volunteers with up to six cohorts (each up to 8 participants; sentinel dosing and Safety Review Committee–managed escalation).
Primary endpoints are safety, tolerability and PK (Cmax, Tmax, AUCs, t1/2) with intensive sampling through 24 hours and a follow-up visit at Day 10. Safety monitoring includes AEs/SAEs, vitals, ECG, labs and injection-site assessments; suicidality monitored using C-SSRS.
Single-ascending subcutaneous doses across up to 6 cohorts (sentinel dosing, cohort escalation by Safety Review Committee).
Cohorts: 5.5, 11, 22, 33, optionally 44 and 38 mg; highest evaluable 52.7 mg; sentinels (1 active, 1 placebo) used in all cohorts.
Normal saline (0.9% sodium chloride) subcutaneous injection; ~2 placebo per cohort.
