  • Publication number: 20240067745
    Abstract: The invention provides an anti-C5 humanized monoclonal antibody with low immunogenicity and low ADCC/CDC function and its application. By modifying the amino acid sequence of the framework region of Eculizumab monoclonal antibody, the immunogenicity was reduced, and the antibody was replaced from IgG2 subtype to IgG1 subtype, and a flexible amino acid sequence was inserted between the CDR3 and CH2 regions of the heavy chain of the IgG1 antibody to reduce the immunogenicity. The purpose of ADCC/CDC function is to improve the stability of the antibody and prolong its half-life. The binding affinity of the monoclonal antibody of the invention to human C5 is similar to that of the original Eculizumab antibody, it can specifically block the complement hemolytic activity of C5 and the production of C5a and can be used for the preparation of C5-targeted paroxysmal nocturnal hemoglobinuria and atypical the drug for the treatment of hemolytic uremic syndrome has excellent clinical therapeutic value.
