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

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.
