Abstract

The success of HER2-targeted cancer therapy is limited by treatment resistance. Here, the authors engineer an anti-HER2 biparatopic antibody with multiple mechanisms of action including induction of HER2 clustering to trigger complement dependent cytotoxicity, signal inhibition, antibody dependent cellular cytotoxicity and phagocytosis.
