  • Publication number: 20200165649
    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 Sia2(?2-6)Gal2GlcNAc2Man3GlcNAc2. The glycoengineered Fc region binds Fc?RIIA or Fc?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?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.

  • Patent number: 9920347
    Abstract: Methods for producing virus particles and viral antigens with simplified glycosylation profiles, such as mono-glycosylated forms of HIV, HCV, Dengue virus, West Nile virus and influenza virus. When used as targets for vaccine production, the conserved nature of such sites generate vaccines that are less sensitive to viral mutations. Such methods may include the use of glycosylation inhibitors for production of viruses or viral antigens with simplified glycosylation profiles.
