Abstract

MEDI4276 is a HER2-bispecific antibody targeting two different epitopes on HER2, with site-specific conjugation via maleimidocaproyl linker to a potent tubulysin-based microtubule inhibitor. MEDI4276 demonstrates enhanced cellular internalization and cytolysis of HER2+ tumor cells in vitro, including T-DM1 resistant cells.
