  • Publication number: 20200223938
    Abstract: The present invention relates to a polypeptide including an Fc variant produced by substituting a portion of the amino acid sequence of the Fc domain of a human antibody with a different amino acid sequence. The present invention also relates to an antibody including the polypeptide. The Fc variant can find application in a wide range of antibodies and Fc-fusion constructs. In one aspect, the antibody or Fc fusion construct of the present invention is a therapeutic, diagnostic or laboratory reagent, preferably a therapeutic reagent. The Fc variant is suitable for use in the treatment of cancer because its in vivo half-life can be maximized by optimization of the portion of the amino acid sequence. The antibody or Fc fusion construct of the present invention is used to kill target cells that bear a target antigen, for example cancer cells. Alternatively, the antibody or Fc fusion construct of the present invention is used to block, antagonize or agonize a target antigen.
