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

Mechanism of action

The therapy involves the isolation of a patient's own chondrocytes, which are then expanded in vitro and seeded onto a scaffold. The resulting construct is implanted into the cartilage defect, where the chondrocytes promote the growth of new cartilage tissue.
