  • Patent number: 6245894
    Abstract: A reshaped human antibody is characterized as having the same binding affinity for IL-8 as a chimeric antibody but with low immunogenicity in comparison. The reshaped antibody has the following elements: a human L chain C region or a human L chain FR and an L chain CDR from a mouse monoclonal antibody against human IL-8 and a human H chain C region or a human H chain FR and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the reshaped human antibody has low immunogenicity to humans, it is suitable for use in medical treatment of a variety of medical conditions.

  • Patent number: 6068840
    Abstract: Monoclonal antibodies immunospecific for the neutrophil chemotactic factor, IL-8, have been humanized by reshaping the variable regions to conform more closely to human counterparts. These antibodies are useful in immunoassays to detect IL-8 and as ligands on immunoaffinity columns for purification of human IL-8. In addition, the humanized antibodies have an antiinflammatory effect in patients.

  • Patent number: 5994524
    Abstract: The present invention discloses a reshaped human antibody against human IL-8 comprising:(A) L chains each comprising:(1) a human L chain C region; and,(2) an L chain V region comprising a human Lchain FR, and an L chain CDR of mouse monoclonal antibody against human IL-8; and,(B) H chains each comprising:(1) a human H chain C region; and,(2) an H chain V region comprising a human Hchain FR, and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the majority of this reshaped human antibody originates in human antibody and the CDR has low antigenicity, the reshaped human antibody of the present invention has low antigenicity to humans, and can therefore be expected to be useful in medical treatment. The present invention further discloses polynucleotides which encode reshaped antibodies against IL-8, as well as host cells and methods to produce these antibodies.
