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
NMPA	CN	2035–2039	+2.3 yr
MFDS	KR	2034–2038	+1.4 yr
CDSCO	IN	2034–2039	+1.8 yr
ANVISA	BR	2035–2039	+2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.
