    Abstract: Provided herein are monovalent antibody constructs. In specific embodiments is a monovalent antibody construct comprising: an antigen-binding polypeptide construct which monovalently binds an antigen; and a dimeric Fc polypeptide construct comprising a CH3 domain, said construct comprising two monomeric Fc polypeptides, wherein one said monomeric Fc polypeptide is fused to at least one polypeptide from the antigen-binding polypeptide construct. These therapeutically novel molecules encompass monovalent constructs that display an increase in binding density and Bmax (maximum binding at a target to antibody ratio of 1:1) to a target cell displaying said antigen as compared to a corresponding monospecific bivalent antibody construct with two antigen binding regions. Provided herein are methods for creation of monovalent antibody constructs that shows superior effector efficacy as compared to the corresponding bivalent antibody construct at equimolar concentrations.

    Abstract: The antibody of the invention has high specificity to human c-Met and is cross-reactive to mouse c-Met. The antibody or its antigen-binding fragment of the invention is capable of specifically binding to human c-Met as well as mouse c-Met, more accurate preclinical results can be confirmed in the efficacy evaluation using mouse tumor models. The antibody of the invention inhibits the growth of cancer cells derived from various cancers by a considerable binding affinity to c-Met and the suppression of c-Met function therefrom, inhibits the phosphorylation of c-Met and downstream signaling molecules to suppress c-Met signaling, and inhibits neovascularization, thereby being very efficient in the prevention and treatment of cancers.

  • Patent number: 8309315
    Abstract: In a wide variety of human solid tumors, an aggressive, metastatic phenotype and poor clinical prognosis are associated with expression of the receptor tyrosine kinase Met. Disclosed herein are (a) a monoclonal antibody named Met4, which antibody is specific for Met, and (b) a hybridoma cell line that produces Met4. The Met4 antibody is particularly useful for detecting Met in formalin-fixed tissue. Methods of using the Met4 antibody for detection, diagnosis, prognosis, and evaluating therapeutic efficacy are provided.

  • Patent number: 8268617
    Abstract: DNAs, vectors, host cells and genetic constructs of antibodies, humanized antibodies, resurfaced antibodies, antibody fragments, derivatized antibodies, and conjugates of these molecules with cytotoxic agents, which specifically bind to and inhibit insulin-like growth factor-I receptor, antagonize the effects of IGF-I and are substantially devoid of agonist activity toward the insulin-like growth factor-I receptor. These molecules can be conjugated to cytotoxic agents for use in the treatment of tumors that express elevated levels of IGF-I receptor, such as breast cancer, colon cancer, lung cancer, ovarian carcinoma, synovial sarcoma and pancreatic cancer. These molecules can also be labeled for in vitro and in vivo diagnostic uses, such as in the diagnosis and imaging of tumors that express elevated levels of IGF-I receptor.

  • Publication number: 20120219991
    Abstract: The present invention provides recombinant proteins comprising the amino acid sequence of an intracellular segment of CD40 and an amino acid sequence mediating the association of the recombinant protein with the constant region of an immunoglobulin heavy chain. The recombinant proteins according to the present invention are useful for inducing clonal expansion of a B cell having a predetermined antigen-specificity without the need for T cell or CD40L mediated co-stimulation. Thus, the present invention provides tools for clonal expansion of B cells specific for an antigen of interest and the production of B cells secreting antibodies specific for an antigen of interest. The recombinant proteins of the present invention may also be used for generating fully human monoclonal antibodies with a predetermined antigen-specificity from the B cell repertoire of a human subject.
