Abstract

The present disclosure provides humanized antibodies that specifically bind to CD3 with an optimized affinity and induce T cell-mediated killing of tumour related target antigen high expressing cells with high potency but have limited killing activity on target antigen low expressing cells. The present disclosure also provides bispecific antibodies comprising a first antigen-binding domain that specifically binds to human CD3 with optimized affinity and a second antigen-binding molecule that specifically binds a tumor-related antigen. The disclosure further relates to methods of generating such humanized antibodies and bispecific antibodies for biological, diagnostic, pharmaceutical and other uses.
