HETERODIMERIC IgG-LIKE BISPECIFIC ANTIBODIES

Abstract:

Novel Heterodimeric IgG-Like Bispecific Antibodies (HILBAs) are provided herein. Such bispecific antibodies are similar to IgG in structure and, thus, do not exhibit a limited half-life like previous antibody fragment-based bispecifics. Moreover, such heterodimeric IgG-like bispecific antibodies advantageously do not entail complicated generation methods such as Fab arm exchange and common light chain methods. Unlike canonical IgG antibodies, the HILBAs described herein include at least one monomer that is from N- to C-terminus: a VH-scFv linker-VL-CL-domain linker-CH1-hinge-CH2-CH3.
