  • Patent number: 10183995
    Abstract: The present invention provides binding molecules (e.g., antibodies or antigen binding fragments thereof) that specifically bind to and inhibit the biological activity of IL-6 (e.g., human, mouse and non-human primate IL-6). In a preferred embodiment, the antibodies or antigen binding fragments of the invention bind to IL-6 and inhibit its binding to an IL-6 receptor. Such antibodies or antigen binding fragments are particularly useful for treating IL-6-associated diseases or disorders (e.g., inflammatory disease and cancer).

  • Patent number: 9926364
    Abstract: Provided are chimeric, camelid-human (e.g., llama-human) polypeptides comprising a first antigenic polypeptide portion and a second antigenic polypeptide portion wherein the first antigenic portion is a derived from a first portion of a camelid (e.g., llama) and the second antigenic portion is a human polypeptide homolog of a second portion of the camedid antigen. The chimeric polypeptides are useful inter alia for epitope mapping and generation of antibodies that bind to a desired region of human antigen.

  • Patent number: 9884917
    Abstract: The present invention relates to antibodies that specifically bind to the human c-Met receptor protein and that act as strict antagonists of hepatocyte growth factor (HGF)-mediated activation of the c-Met receptor and also inhibit HGF-independent activation of the human c-Met protein.

  • Patent number: 9688773
    Abstract: The invention provides a product combination or composition, and also multispecific antibodies comprising two or more antigen-binding sites (as antibodies or antigen binding fragments thereof), wherein two the antigen-binding bind to distinct non-overlapping epitopes of the human c-Met protein. The product combination or composition or multispecific antibody inhibits HGF-independent activation of the human c-Met receptor protein.

  • Patent number: 9346891
    Abstract: The invention relates to a platform technology for production of antigen binding polypeptides having specificity for a desired target antigen which is based on the conventional antibody repertoire of species in the family Camelidae, and to antigen binding polypeptides obtained using this technology platform. In particular, the invention provides an antigen binding polypeptide comprising a VH domain and a VL domain, wherein at least one hypervariable loop or complementarity determining region (CDR) in the VH domain or the VL domain is obtained from a VH or VL domain of a species in the family Camelidae.

  • Publication number: 20150203840
    Abstract: A method is disclosed for producing an antibody molecule having inter-species, intra-target cross-reactivity. The method comprises the steps of creating a first immune library for a target antigen from a first species, for example man; combining variable regions from the first immune library in a chain shuffling protocol, to produce a second immune library; and screening the second immune library for affinity to both the target antigen and a corresponding antigen from a second species. The second species is different from the first species. By using a suitable test animal as the second species, the method paves the way to convenient testing of the antibody molecule.
