Summary for Patent: 10,023,892
Title:Compositions and methods relating to universal glycoforms for enhanced antibody efficacy
Abstract: The present disclosure relates to glycoproteins, particularly monoclonal antibodies, comprising a glycoengineered Fc region, wherein said Fc region comprises an optimized N-glycan having the structure of Sia.sub.2(.alpha.2-6)Gal.sub.2GlcNAc.sub.2Man.sub.3GlcNAc.sub.2. The glycoengineered Fc region binds Fc.gamma.RIIA or Fc.gamma.RIIIA with a greater affinity, relative to comparable monoclonal antibodies comprising the wild-type Fc region. The monoclonal antibodies of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by Fc.gamma.R is desired, e.g., cancer, autoimmune, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.
