Abstract

Un objeto de la presente invención es proporcionar un anticuerpo biespecífico anti– CLDN4/anti–CD137 utilizable en el tratamiento del cáncer. Un anticuerpo biespecífico anti–CLDN4/anti–CD137 producido utilizando un anticuerpo anti–CLDN4 que se une a CLDN4 y un anticuerpo anti–CD137 que se une a CD137 tenía actividad agonística para CD137, promovía la producción de interferón γ por una célula T y mostraba actividad citotóxica contra una célula cancerosa que expresaba CLDN4 en una superficie celular de la misma. Además, se demostró que el anticuerpo biespecífico anti–CLDN4/anti–CD137 puede administrarse con seguridad a los monos. Por lo tanto, el anticuerpo biespecífico anti–CLDN4/anti–CD137 es utilizable en el tratamiento del cáncer humano.
