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).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
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

Mechanism of action

This is a multimodal treatment approach for gastric cancer that combines surgical resection of the stomach (gastrectomy) with perioperative or adjuvant chemotherapy. The chemotherapy component typically uses platinum-based and fluoropyrimidine agents to eliminate micrometastatic disease and improve overall survival beyond surgery alone.
