  • Patent number: 9028815
    Abstract: The present invention relates to molecules, particularly polypeptides, more particularly immunoglobulins (e.g., antibodies), comprising a variant Fc region, wherein said variant Fc region comprises at least one amino acid modification relative to a wild-type Fc region, which variant Fc region binds Fc?RIIIA and/or Fc?RIIA with a greater affinity, relative to a comparable molecule comprising the wild-type Fc region. The molecules of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection. The molecules of the invention are particularly useful for the treatment or prevention of a disease or disorder where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by Fc?R is desired, e.g., cancer, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.

  • Patent number: 8216574
    Abstract: The present invention relates to molecules having a variant Fc region, wherein said variant Fc region comprises at least one amino acid modification relative to a wild-type Fc region. These modified molecules confer an effector function to a molecule, where the parent molecule does not detectably exhibit this effector function. In particular, the molecules of the invention have an increased effector cell function mediated by a Fc?R, such as, but not limited to, ADCC. In one embodiment, the variant Fc region binds Fc?RIIIA and/or Fc?RIIA with a greater affinity, relative to a comparable molecule comprising the wild-type Fc region.
