  • Publication number: 20230226177
    Abstract: Provided herein are formulations of PCSK9-binding polypeptides, such as those comprising evolocumab, that comprise N-acetyl arginine and have reduced viscosities when compared to formulations lacking N-acetyl arginine. Provided herein are also methods of formulating such compositions that are advantageous in that they conserve certain components. Such formulations comprising PCSK9-binding polypeptides can be administered to patients to treat and/or prevent PCSK9-related diseases, conditions, and disorders.
    Type: Application

  • Publication number: 20220251502
    Abstract: The present disclosure relates to methods for reducing the oxidation level of cysteine residues in recombinant polypeptides such as anti-IL-17 antibodies during cell culture (e.g., a preparation of secukinumab antibodies) that have been recombinantly produced by mammalian cells. Also provided are purified preparations of recombinant polypeptides such as anti-IL-17 antibodies or antigen binding fragments thereof produced by such methods, e.g, purified preparations of secukinumab. Also provided are purified preparations of recombinant polypeptides produced by such methods wherein the level of active recombinant polypeptide in the preparation is high.
