Abstract

Se refiere a un anticuerpo biespecifico heterodimerico que comprende un primer dominio funcional de union a antigeno capaz de unirse especificamente a PD-1 y un segundo dominio funcional de union a antigeno capaz de unirse especificamente a HER2, comprendiendo el anticuerpo una primera cadena Fc y una segunda cadena Fc unidas entre si por uno o mas enlaces disulfuro, y unidas a los dominios funcionales de union a antigeno PD-1 y HER2 mediante enlace covalente o enlazador, comprendiendo estas cadenas 5 sustituciones de aminoacidos: en las posiciones T366 y D399 (o K409) de la primera cadena Fc y en las posiciones L351, Y407 y K409 (o D399) de la segunda cadena Fc, tendiendo las cadenas a experimentar heterodimerizacion. Tambien se refiere a un polinucleotido aislado que codifica al anticuerpo, un vector de expresion y una celula huesped que comprenden al polinucleotido, una composicion que comprende el anticuerpo, y metodos de preparacion. La presente invencion es util para el tratamiento de enfermedades complejas tales como leucemia, linfoma, entre otras
