Abstract: The present disclosure relates to bispecific antibodies targeting EGFR and HER2, and methods for the production of these antibodies. The bispecific antibodies consist of one complete antibody on which two VH-VL chains are attached via a linker to each NH terminal region of both VH chains of the antibody. The bispecific antibodies constructed use the amino acid sequences of the heavy chain (VH) and the light chain (VL) variable regions of two monoclonal antibodies targeting EGFR and HER2, namely cetuximab and trastuzumab, respectively.

Abstract: This application describes binding proteins that specifically bind to EGFRvIII and multispecific binding proteins that specifically bind to EGFRvIII and CD3. Further described is a multispecific tandem diabody that binds to EGFRvIII and CD3. Further described are highly cytotoxic EGFRvIII/CD3 bispecific tandem diabody for recruiting T cells to specifically and potently kill several types of solid tumor cancer.
