Abstract

La invención se refiere a anticuerpos anti-CAIX que comprenden una región constante de cadena pesada que comprende una o más sustituciones de aminoácidos en comparación con una IgG de tipo natural, en donde la una o más sustituciones de aminoácidos reducen la afinidad del anticuerpo por el receptor de Fc neonatal (FcRn), reduciendo de ese modo la semivida sérica del anticuerpo modificado en comparación con un anticuerpo de tipo natural de clase IgG. La una o más modificaciones de aminoácidos que tienen el efecto de reducir la unión a FcRn se seleccionan de las posiciones His310, His433, His435, His436, Ile253. Los anticuerpos de la presente invención son particularmente idóneos para su uso en radioinmunoterapia.
