ANTIBODY COMPOSITIONS COMPRISING FC MUTATIONS AND SITE-SPECIFIC CONJUGATION PROPERTIES

摘要

Antibodies that bind Her2, EGFR, Trop2, CDH3 or other TAAs containing a triple mutation at L234A, L235A, and L328C and methods of making such triple mutated antibodies are disclosed herein. Consequently, the triple mutated antibodies contain a modified effector function through Fc silencing and are capable of site-specific conjugation at L328C to form an antibody-drug-conjugate (ADC) which can be administered to patients and provide a method of treating cancer, immunological and neurological disorders.
