Likelihood of approval
12.6% 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).
  • Big-pharma sponsor +3.0pp
    AstraZeneca is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
Predicted approval windows by jurisdiction (conditional on FDA approval)
