  • Publication number: 20180346590
    Abstract: In one aspect, the present invention relates to an antigen-binding molecule specific for albumin and CD3 which may comprise two polypeptide chains, each polypeptide chain having at least four variable domains in an orientation preventing Fv formation and the two polypeptide chains are dimerized with one another thereby forming a multivalent antigen-binding molecule. On each of the two polypeptide chains the four variable domains may be arranged in the order VLA-VHB-VLB-VHA from the N-terminal to the C-terminal of the polypeptide. Compositions of the antigen-binding molecule and the methods of using the antigen-binding molecule or the compositions thereof for treatment of various diseases are also provided herein.

  • Patent number: 10066015
    Abstract: The invention relates to a humanized CD3 binding site, which comprises (a) a variable heavy chain domain (VH) as depicted in SEQ ID NO:8 and a variable light chain domain (VL) as depicted in SEQ ID NO:3; or (b) a variable heavy chain domain (VH) as depicted in SEQ ID NO:9 and a variable light chain domain (VL) as depicted in SEQ ID NO:4, or c) a variable heavy chain domain (VH) as depicted in SEQ ID NO:7 and a variable light chain domain (VL) as depicted in SEQ ID NO:2; or (d) a variable heavy chain domain (VH) as depicted in SEQ ID NO:6 and a variable light chain domain (VL) as depicted in SEQ ID NO:1. The CD3 binding sites have an increased stability, while the binding affinity has been retained due to mutations at positions VH111 and VL49.
