Abstract

La presente invención proporciona agentes de unión que comprenden al menos dos dominios de unión, donde un primer dominio de unión tiene especificidad para CLDN18.2 y un segundo dominio de unión tiene especificidad para CD3, y métodos para el uso de estos agentes de unión o ácidos nucleicos que los codifican para el tratamiento del cáncer. Un agente de unión caracterizado porque comprende un dominio de unión con especificidad para CLDN18.2 y un dominio de unión con especificidad para CD3, donde el agente de unión comprende al menos tres cadenas de polipéptidos, donde (I) una primera cadena de polipéptidos comprende una región variable de una cadena pesada (VH) derivada de una inmunoglobulina con especificidad para CLDN18.2 (VH(CLDN18.2)), (II) una segunda cadena de polipéptidos comprende una VH derivada de una inmunoglobulina con especificidad para CD3 (VH(CD3)) y una región variable de una cadena ligera (VL) derivada de una inmunoglobulina con especificidad para CD3 (VL(CD3)), y (III) una tercera cadena de polipéptidos comprende una VL derivada de una inmunoglobulina con especificidad para CLDN18.2 (VL(CLDN18.2)). Un agente de unión caracterizado porque comprende un dominio de unión con especificidad para CLDN18.2 que comprende una región variable de una cadena pesada (VH) derivada de una inmunoglobulina con especificidad para CLDN18.2 (VH(CLDN18.2)) y una región variable de una cadena ligera (VL) derivada de una inmunoglobulina con especificidad para CLDN18.2 (VL(CLDN18.2)), donde la VH(CLDN18.2) comprende a CDR1 que comprende la secuencia de aminoácidos SYWIN (SEQ ID Nº 32), un CDR2 que comprende la secuencia de aminoácidos NIYPSDSYTNYNQKFQG (SEQ ID Nº 33), y un CDR3 que comprende la secuencia de aminoácidos SWRGNSFDY (SEQ ID Nº 34) y la VL(CLDN18.2) comprende a CDR1 que comprende la secuencia de aminoácidos KSSQSLLNSGNQKNYLT (SEQ ID Nº 35), un CDR2 que comprende la secuencia de aminoácidos WASTRES (SEQ ID Nº 36), y un CDR3 que comprende la secuencia de aminoácidos QNDYSYPFT (SEQ ID Nº 37). Un agente de unión caracterizado porque comprende dos dominios de unión con especificidad para CLDN18.2 y un dominio de unión con especificidad para CD3, donde el agente de unión comprende cuatro cadenas de polipéptidos, donde (I) la primera cadena de polipéptidos comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 73, (II) la segunda cadena polipeptídica comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 74, (III) la tercera cadena polipeptídica comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 78 y (IV) la cuarta cadena de polipéptidos es idéntica a la tercera cadena de polipéptidos, donde la primera cadena de polipéptidos interactúa con la segunda cadena de polipéptidos y con la tercera cadena de polipéptidos, y la segunda cadena de polipéptidos interactúa con la cuarta cadena de polipéptidos. Un agente de unión caracterizado porque comprende un dominio de unión con especificidad para CLDN18.2 y un dominio de unión con especificidad para CD3, donde el agente de unión comprende tres cadenas de polipéptidos, donde (I) la primera cadena de polipéptidos comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 73, (II) la segunda cadena polipeptídica comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 75 y (III) la tercera cadena polipeptídica comprende o consiste en una secuencia de aminoácidos representada por la SEQ ID Nº 78, donde la primera cadena de polipéptidos interactúa con la segunda cadena de polipéptidos y con la tercera cadena de polipéptidos.
