Likelihood of approval

9.6% vs 9.6% industry baseline

If approved by FDA: likely 2033–2036

Steps remaining: Phase 2 → Phase 3 → NDA/BLA submission

Confidence: Medium

Why this estimate

Baseline phase 1 → approval rate +9.6pp
Industry-wide phase 1 drugs reach approval ~9.6% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).

Predicted approval windows by jurisdiction (conditional on FDA approval)

Regulator	Country	Likely year	Lag vs FDA
FDA	US	2033–2036	—
EMA	EU	2034–2037	+0.7 yr
MHRA	GB	2034–2037	+0.7 yr
Health Canada	CA	2034–2038	+0.9 yr
TGA	AU	2034–2038	+1.2 yr
PMDA	JP	2034–2038	+1.5 yr
