What is ZW251?

ZW251 is an antibody-drug conjugate composed of a humanized IgG1 monoclonal antibody targeting glypican 3 conjugated to ZD06519, a camptothecin-based topoisomerase 1 inhibitor. Upon binding to GPC3 on tumor cells, the antibody delivers ZD06519, which inhibits topoisomerase 1 activity, causing DNA strand breaks, cell cycle arrest, and apoptosis. It is studied in hepatocellular carcinoma, squamous cell non-small cell lung cancer, and germ cell tumors.
