  • Publication number: 20200341014
    Abstract: The present invention provides a method for evaluating the pharmacological action of HGF that utilizes a PD marker in which fluctuation is recognized by administration of hepatocyte growth factor (HGF) in a broader range of subjects. A method for evaluating the pharmacodynamic action of HGF is provided. The aforementioned evaluation method is characterized in that it comprises a step of measuring the ApoA4 level in a biological sample collected from a test subject who was administered HGF. According to the present invention, a kit for evaluating the pharmacodynamic action of HGF comprising an anti-ApoA4 antibody is further provided.

  • Patent number: 9809647
    Abstract: The present invention relates to novel humanized, chimeric and murine antibodies that have binding specificity for the human CC chemokine ligand 20 (CCL20). The present invention further relates to heavy chains and light chains of said antibodies. The invention also relates to isolated nucleic acids, recombinant vectors and host cells that comprise a sequence which encodes a heavy chain and/or a light chain of said antibodies, and to a method of preparing said antibodies. The anti-CCL20 antibodies of the invention can be used in therapeutic applications to treat, for example, inflammatory and autoimmune disorders and cancer.
