Abstract
La presente invención se refiere a un método in vitro para identificar/seleccionar una proteína terapéutica modificada que es una proteína antitumor que trata tumores y que tiene una mayor actividad en un microambiente de tumor en un sujeto comparado con un ambiente sin tumor en el sujeto, caracterizado porque comprende: i) probar la actividad de unión de una pluralidad de proteínas terapéuticas anti-tumor modificadas al objetivo de las proteínas terapéuticas anti-tumor bajo las condiciones a) y bajo las condiciones b), en donde: las proteínas terapéuticas anti-tumor son anticuerpos o porciones de unión al antígeno de los mismos; la condiciones en a) comprende pH bajo que está entre 5.8 y 6.8, y suero humano; las condiciones en b) comprende pH que está entre 7.2 y 7.8, y suero humano en la misma concentración que en a); la concentración de suero en ambas condiciones es la misma y es 15-35% en volumen; opcionalmente, las condiciones en a) en comparación con las condiciones en b) comprenden una o más propiedades adicionales a pH reducido seleccionadas de entre hipoxia, concentración de lactato incrementada y concentración de piruvato incrementada; el resto de las condiciones en a) y b) son las mismas; la actividad probada es la unión a la proteína objetivo de la proteína terapéutica; cada proteína terapéutica modificada contiene reemplazo de aminoácido, inserción y/o eliminación de un residuo o residuos de aminoácido comparados con la forma no modificada de la proteína terapéutica; y cada proteína modifica se prueba en cada una de las condiciones de a) y b); ii) comparar la actividad de unión de las proteínas terapéuticas modificadas en a) con la actividad de unión en b); y iii) seleccionar/identificar una proteína terapéutica modificada que tiene mayor actividad de unión para la proteína objetivo en a) comparada con b), de este modo identificando un anticuerpo terapéutico modificado o porción de unión al antígeno del mismo que es condicionalmente activo tal que tiene mayor actividad de unión en las condiciones de pH bajas de un microambiente de tumor comparado con las condiciones de pH de un ambiente sin tumor.
