Likelihood of approval
59.3% 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).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr

Mechanism of action

Eculizumab binds to C5, a key component of the complement cascade, preventing its cleavage into C5a and C5b. This blocks the terminal complement pathway and prevents formation of the C5b-9 membrane attack complex, which would otherwise cause cell lysis. By inhibiting this pathway, eculizumab reduces complement-mediated hemolysis and tissue damage in complement-driven diseases.
