  • Patent number: 7645450
    Abstract: Humanized antibodies specifically binding to hTNF-? are prepared from a mouse monoclonal antibody by the CDR (complementarity determining region) grafting method, and they show an antigen binding affinity similar to the original mouse monoclonal antibody and significantly low immunogenicity. Therefore, the humanized antibodies can be effectively used for treating a hTNF-?-related disease such as rheumatoid arthritis, Crohn's disease, psoriatic arthritis, psoriasis, septicemia, asthma, Wegener's granulomatosis, inflammation, and ankylosing spondylitis.
