Abstract
La présente invention concerne l'utilisation d'un anticorps anti-cd25, qui n'inhibe pas l'interaction il-2-cd25, avec une liaison améliorée pour activer des rs gamma fc qui conduisent à un épuisement efficace de cellules treg infiltrant les tumeurs et une meilleure maîtrise de tumeurs établies. Selon l'invention, la combinaison avec des anticorps anti-protéine-1 de mort cellulaire programmée améliore en outre le rejet tumoral.The present invention relates to the use of an anti-cd25 antibody, which does not inhibit il-2-cd25 interaction, with enhanced binding to activate rs gamma fc which leads to effective depletion of Treg cells infiltrating the tumors and better control of established tumors. According to the invention, the combination with anti-programmed cell death protein-1 antibodies further improves tumor rejection.
