  • Publication number: 20240052059
    Abstract: The present inventors examined the procoagulant activity of a multispecific antigen-binding molecule that functionally substitutes for FVIII using blood and plasma derived from FIX disorder patients. The result showed that multispecific antigen-binding molecules that functionally substitute for FVIII can be used not only as methods for preventing and/or treating bleeding in hemophilia A, acquired hemophilia A, von Willebrand disease, and hemophilia C, which are caused by FVIII dysfunction, but also as methods for preventing and/or treating bleeding in FIX disorders, because of their procoagulant activity. Furthermore, the effect of a FIX formulation could be enhanced by using it in combination with a multispecific antigen-binding molecule that functionally substitutes for FVIII, and it was shown that the combined use is promising as a combination therapy that shows stable hemostatic effects.

  • Publication number: 20240010738
    Abstract: The present invention provides pharmaceutical compositions comprising second-generation molecules that are superior than TOCILIZUMAB, by altering the amino acid sequences of the variable and constant regions of TOCILIZUMAB, which is a humanized anti-IL-6 receptor IgG1 antibody, to enhance the antigen-neutralizing ability and increase the pharmacokinetics, so that the therapeutic effect is exerted with a less frequency of administration, and the immunogenicity, safety and physicochemical properties (stability and homogeneity) are improved. The present invention also provides methods for producing these pharmaceutical compositions. The present inventors have successfully generated second-generation molecules that are superior to TOCILIZUMAB by appropriately combining amino acid sequence alterations in the CDR domains, variable regions, and constant regions.

    Abstract: An objective of the present invention is to obtain two types of substantively homogeneous cancer stem cell populations which can be characterized using the cell surface marker Lgr5, and to provide cancer therapeutics using an antibody against a cell membrane molecule specifically expressed in these cancer stem cells by identifying said cell membrane molecule. A further objective is to provide, using an antibody against a cell membrane molecule specifically expressed in cancer stem cells, a reagent for detecting cancer stem cells, and a method for diagnosing and sorting cancer patients. The present inventors discovered that highly pure large intestine cancer stem cells (CSC) can be obtained in a large quantity, and identified the two types of conditions of large intestine CSCs distinguishable through Lgr5 expression. Moreover, the present inventors discovered that an antibody against a cell membrane molecule specifically expressed in said cancer stem cells can damage said cells.

  • Patent number: 11851486
    Abstract: It has become clear that the therapeutic effect of an IL-6 inhibitor for IL-6- and neutrophil-associated diseases can be predicted using the expression level of neutrophil-associated genes as an indicator. It has also become clear that an IL-6 inhibitor is effective for the treatment of IL-6- and neutrophil-associated diseases in patients with high expression levels of neutrophil-associated genes. The present invention provides a method for selecting cases of IL-6- and neutrophil-associated diseases in which treatment with an IL-6 inhibitor is effective, as well as a method for effectively treating patients with IL-6- and neutrophil-associated diseases and with high expression levels of neutrophil-associated genes.
