  • Anti-CLDN4/anti-CD137 bispecific antibody
    Patent number: 12227586
    Abstract: An object of the present invention is to provide an anti-CLDN4/anti-CD137 bispecific antibody usable in treatment of cancer. An anti-CLDN4/anti-CD137 bispecific antibody produced using an anti-CLDN4 antibody binding to CLDN4 and an anti-CD137 antibody binding to CD137 had agonistic activity for CD137, promoted production of interferon ? by a T cell, and exhibited cytotoxic activity against a cancer cell expressing CLDN4 on a cell surface thereof. Besides, it was shown that the anti-CLDN4/anti-CD137 bispecific antibody can be safely administered to monkeys. Therefore, the anti-CLDN4/anti-CD137 bispecific antibody is usable in treatment of human cancer.
