Single Ascending Dose Study With BPL-003 in Healthy Subjects

Phase 1, placebo-controlled, single ascending dose trial to evaluate the safety, pharmacokinetics and effect on altered states of consciousness of intranasal BPL-003 (5-methoxy-N,N-dimethyltryptamine benzoate) in healthy participants

In this double-blind, placebo-controlled Phase 1 trial, intranasal BPL-003 (5‑MeO‑DMT benzoate) was well tolerated up to 12 mg and showed rapid absorption and elimination with dose‑proportional systemic exposure (Tmax ≈ 8–10 min; mean terminal half‑life <27 min) and negligible bufotenine formation. Pharmacodynamic effects scaled with plasma concentrations, producing profound, short‑lasting consciousness‑altering and mystical experiences—60% of participants had a complete mystical experience at 10–12 mg—supporting further clinical evaluation.
