Publication number: 20240150465Abstract: The present inventors discovered novel multispecific antigen-binding molecules with excellent cellular cytotoxicity, which comprise a first domain comprising a first antigen variable region which binds to DLL3 and a second domain comprising a second antigen variable region which binds to T cell receptor complex. The present inventors prepared further bispecific antibodies, and assessed their T cell-dependent cell cytotoxicity (TDCC), and found that they also show strong TDCC activity. Since the molecules/antibodies of the present invention show a strong cytotoxicity against cells expressing DLL3, novel pharmaceutical compositions comprising the molecules/antibodies for treating or preventing various cancers associated with DLL3 can be provided.Type: ApplicationFiled: May 2, 2023Publication date: May 9, 2024Inventors: Shogo KAMIKAWAJI, Yasuko KINOSHITA, Shinya ISHII
