  • Patent number: 9522956
    Abstract: The invention relates to the combined use of anti-EGFR antibodies and anti-Her2 antibodies for the treatment of cancer, especially suitable for cancer expressing high levels of the EGFR type and low levels of HER2. The invention refers in particular monoclonal antibody “trastuzumab” (HERCEPTIN®) directed against the HER2 receptors the efficacy of which can be significantly increased in vivo when combined with monoclonal antibody “matuzumab” (hmAB 425, EMD 72000) directed against EGF receptors. The combination treatment is suitable for patients suffering from cancer having said receptor profile, preferably pancreatic cancer.

  • Publication number: 20150141626
    Abstract: Disclosed are compositions and methods for producing fusion proteins with reduced immunogenicity. Fusion proteins of the invention include a junction region having an amino acid change that reduces the ability of a junctional epitope to bind to MHC Class II, thereby reducing its interaction with a T-cell receptor. Methods of the invention involve analyzing, changing, or modifying one or more amino acids in the junction region of a fusion protein in order to identify a T-cell epitope and reduce its ability to interact with a T cell receptor. Compositions and methods of the invention are useful in therapy.
