  • Publication number: 20190153104
    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.

  • Publication number: 20170298129
    Abstract: Disclosed are processes for producing a variant polypeptide (e.g. antibodies) having modified binding characteristics for human Fc gamma receptor IIA (CD32A) leading to increased inhibition of proinflammatory mediators while retaining binding to a target antigen via its Fv portion, which processes comprise altering the polypeptides by substitution of at least two amino acid residues at EU position 325, 326 or 328 of a human IgG CH2 region for a sequence selected from SAAF, SKAF, NAAF and NKAF. The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof.
