Zanidatamab zovodotin (ZW49) induces hallmarks of immunogenic cell death and is active in patient-derived xenograft models of gastric cancer (Section 13; Poster Board #1) - Mar 14, 2023 - Abstract #AACR2023AACR_4860; P1 Anti-tumor activity was observed in 5/7 (71%) PDX models of gastric cancer after a single i.v. dose of 6 mg/kg, including in models with moderate and weak HER2 expression. The strong anti-tumor activity of ZW-49 in vivo, together with its ability to induce ICD and potential adaptive immune responses, support ZW49 as a promising ADC for the treatment of HER2-expressing cancers warranting further investigation, including potential combination with checkpoint inhibitors.
