Een veiligheids- en werkzaamheidsstudie van ZW25 (Zanidatamab) plus combinatiechemotherapie bij gastro-intestinale kankers die HER2 tot expressie brengen, waaronder gastro-oesofageaal adenocarcinoom, galwegkanker en colorectale kanker

13 oktober 2026 bijgewerkt door: Jazz Pharmaceuticals

Fase 2-studie van ZW25 Plus eerstelijns combinatiechemotherapie bij HER2-expressie van gastro-intestinale (GI) kankers, waaronder gastro-oesofageaal adenocarcinoom (GEA), galwegkanker (BTC) en colorectale kanker (CRC)

This is a multicenter, global, Phase 2, open-label, 2-part, first-line study to investigate the safety, tolerability, and anti-tumor activity of ZW25 (zanidatamab) plus standard first-line combination chemotherapy regimens for selected gastrointestinal (GI) cancers. Eligible patients include those with unresectable, locally advanced, recurrent or metastatic HER2-expressing gastroesophageal adenocarcinoma (GEA), biliary tract cancer (BTC), or colorectal cancer (CRC).

Gedetailleerde beschrijving

Part 1 of the study will first evaluate the safety and tolerability of ZW25 plus standard first-line combination chemotherapy (XELOX, FP, or mFOLFOX6 for GEA; mFOLFOX6 with or without bevacizumab for CRC; and CisGem for BTC) and will confirm the recommended dosage (RD) of ZW25 when administered in combination with each of these multi-agent chemotherapy regimens. Then, Part 2 of the study will evaluate the anti-tumor activity of ZW25 plus combination chemotherapy in HER2-expressing GEA, BTC, and CRC.
