  • Patent number: 9238691
    Abstract: Provided are antibodies including human antibodies and antigen-binding portions thereof that specifically bind to CCR2, preferably human CCR2, and that may inhibit CCR2. The present antibodies may bind to the first and/or second extracellular loops of CCR2. Isolated heavy and light chains derived from the antibodies and nucleic acid molecules encoding the antibodies and chains are provided. Methods of making and using the anti-CCR2 antibodies or antigen-binding portions, and compositions comprising these antibodies or antigen-binding portions, including compositions for diagnosis and treatment, are provided. Also provided are gene therapy methods using nucleic acid molecules encoding the heavy and/or light chains that comprise the human anti-CCR2 antibodies or antigen-binding portions thereof.

  • Publication number: 20150266974
    Abstract: The present invention relates to antibodies with pH dependent binding to its antigen such that the affinity for antigen binding at physiological pH (i.e., pH 7.4) is greater than at endosomal pH (i.e., pH 6.0 or 5.5). In other words, the KD or koff ratio at pH 5.5/pH 7.4 or at pH 6.0/pH 7.4 is more than, or ranges between, 2, 3, 4, 8, 10, 16, 20, 30, 40, or 100 or more. Such pH dependent antibodies preferentially dissociate from the antigen in the endosome. This can increase antibody half life, as compared to antibodies with equivalent KDs at pH 7.4 but with no pH dependent binding, when the antigen is one that undergoes antigen-mediated clearance (e.g., PCSK9). Antibodies with pH dependent binding can decrease total antigen half life when the antigen undergoes reduced clearance when bound to antibody (e.g., IL6). Antibodies with pH dependent binding can also prolong the decrease in antigen which is not antibody-bound.
