We work on drug discovery by combining our proprietary global top level antibody engineering and cyclic peptide technology and biological hypothesis of disease causing mechanism to solve the unmet medical needs.

Bispecific Antibody

A bispecific antibody can bind to two different antigens with the two arms of the antibody. We have established bispecific antibody technology to enable commercial level manufacturing. We have discovered bispecific IgG antibody recognizing FIXa and FX, which mimics the function of FVIII, for the treatment of haemophilia A. Our bispecific antibody technology has been applied to create FDA-approved product, HEMLIBRA® (emicizumab), the world first recombinant bispecific IgG antibody, and we have multiple bispecific antibodies that are now being tested in clinical study and in the drug discovery stage.
