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).
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
TGA AU 2029–2032 +1.2 yr

Mechanism of action

Gelofusine is a modified fluid gelatin (succinylated gelatin) that functions as a colloid, meaning its large molecular weight particles remain in the bloodstream longer than crystalloid solutions. It restores intravascular volume and improves tissue perfusion in hypovolemic states by osmotic pressure, helping to maintain hemodynamic stability during surgery, trauma, or critical illness.
