Nuovi ingaggi cellulari bispecifici che superano la resistenza acquisita EGFR.

Epidermal growth factor receptor (EGFR) is a validated therapeutic target in several human cancers harboring wild-type KRAS. However, intrinsic and acquired resistance to EGFR-targeted antibody therapies such as cetuximab remains a major limitation to achieving broad and durable treatment responses. Extensive clinical and translational studies have shown that resistance frequently arises from missense mutations within the extracellular domain (ECD) of EGFR. In this study, we developed novel antagonistic EGFR antibodies that bind epitopes overlapping but distinct from the cetuximab-binding site while retaining high affinity for all major EGFR ECD escape variants. Antibody binding effectively
