Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Big-pharma sponsor +3.0pp
    Bayer is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.

Mechanism of action

BAY94-9027 is a recombinant human coagulation factor VIII conjugated with polyethylene glycol (PEG), which increases its circulating half-life compared to conventional factor VIII products. This extended half-life allows for less frequent dosing while maintaining therapeutic factor VIII levels, improving convenience and compliance in hemophilia A management. The drug functions as a direct replacement of the deficient clotting factor in the intrinsic coagulation pathway.
