  • Patent number: 11660340
    Abstract: The present invention provides methods for treating or preventing cancer by administering an anticancer agent and an antigen-binding molecule comprising a domain that binds to a molecule expressed on the surface of a cell having an immune response-suppressing function and a T cell receptor complex-binding domain. The present invention also provides pharmaceutical compositions for treating or preventing cancer, each comprising a combination of the anticancer agent and the antigen-binding molecule.

  • Publication number: 20210388110
    Abstract: The present invention provides anticancer agents comprising as an active ingredient a bispecific antibody that comprises a domain comprising a glypican 3-binding antibody variable region, a domain comprising a T cell receptor complex-binding antibody variable region, and common L chains that can enhance the affinity for the two antigens, as well as pharmaceutical compositions comprising the bispecific antibody as an active ingredient, the compositions being for use in combination with other anticancer agents. The bispecific antibodies are novel molecules which are produced with high efficiency and have strong anti-tumor activity as well as safety and excellent pharmacodynamics. The bispecific antibodies can be expected to be applied to various cancers.

  • Publication number: 20180326058
    Abstract: It was discovered that antigen-binding molecules comprising (1) a domain that binds to a molecule expressed on the surface of cells having immune response-suppressing functions and (2) a T cell receptor complex-binding domain, crosslink T cells with the cells having immune response-suppressing functions and induce damage to the cells having immune response-suppressing functions to thereby exhibit more superior antitumor effects than conventional antigen-binding molecules. It was also discovered that combined use of the antigen-binding molecules and other anticancer agents further increases the antitumor effects.
