Bispecific antibody-drug conjugates (ADCs) targeting dual tumor-associated antigens (TAAs) offer advantages in fighting against cancer. These include
the ability to simultaneously target multiple tumor-driven proteins, potentially overcoming drug resistance.
recognize cells co-expressing both targets to increase tumor specificity and reducing off-target toxicity.
the combination of two targets increases the internalization and thus tumor killing.
Improving the enrichment and exposure of ADCs in tumor tissues for stronger and longer lasting killing of heterogeneous tumors
Advantages of Biocytogen’s novel bsADC platform
RenLite-derived common light chain antibodies are easy to assemble into BsAb with low mismatch rate and ideal physiochemical properties.
Combined with target gene knockout strategy, RenLite KO mice can generate antibodies with increased diversity, potentially against novel epitopes and with cross-species reactivity.
Proprietary linker/payload system BLD1102
Rapid generation of high-quality BsAbs/BsADCs for high-throughput in vitro and in vivo screening
Novel linker/payload system BLD1102 independently developed by Biocytogen
Briefly, BLD1102 is a new ADC platform developed by Biocytogen independently.
BCPT02 is a novel topoisomerase 1 inhibitor with broad-spectrum and potent tumor killing ability.
The uniquely designed cleavable linker has excellent hydrophilicity, making ADCs as hydrophilic as monoclonal antibodies, greatly improving ADC’s physiochemical properties.
BLD1102-ADCs exhibit good stability in plasma and more potent tumor killing compared to vcMMAE.
BLD1102 demonstrated good tolerabilities in preclinical non-human primates.
