  • Publication number: 20230235056
    Abstract: The present disclosure provides methods for preventing, alleviating, or treating cytokine release resulting from administration of a VEGF inhibitor or side effects resulting from the cytokine release. To prevent, alleviate, or treat cytokine release or its side effects, the disclosure also provides combination therapies that use a lymphocyte-stimulating pharmaceutical agent, represented by an anti-T cell antigen-binding molecule, with a VEGF inhibitor. Among the anti-T cell antigen-binding molecules, for example, antibodies that recruit T cells as effector cells into tumor tissues are called T cell redirecting antibodies, and are known as means for treating tumors. On the other hand, when systemic cytokine production is stimulated by binding of antibodies to T cells, it is feared that this systemic action will lead to aberrations such as CRS.

  • 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: 20210230311
    Abstract: Novel multispecific antigen-binding molecules maintaining excellent cellular cytotoxicity and high stability, which comprise a domain that contains an antibody variable region having glypican 3-binding activity and a domain that contains an antibody variable region having T-cell receptor complex-binding activity, were discovered. Since the molecules of the present invention show a strong cytotoxicity against cells and tissues expressing glypican 3, it is possible to produce novel pharmaceutical compositions for treating or preventing various cancers.
