  • Patent number: 10023623
    Abstract: The present invention provides fusion proteins comprising a mucin-domain polypeptide covalently linked to an active protein that has improved properties (e.g. pharmacokinetic and/or physicochemical properties) compared to the same active protein not linked to mucin-domain polypeptide, as well as methods for making and using the fusion proteins of the invention.
    Type: Grant
    Filed: September 1, 2015
    Date of Patent: July 17, 2018
    Assignee: Alkermes, Inc.
    Inventors: Juan Alvarez, Jean Chamoun, Heather C. Losey
  • Patent number: 9359415
    Abstract: The present invention provides fusion polypeptides comprising polypeptide ligands that are modified by circular permutation and fused to at least one polypeptide fusion partner wherein such fusion polypeptides have new, improved or enhanced biological functions or activities. Such improvements include, but are not limited to, increased binding affinity, increased activity, increased agonist activity (super agonist), antagonist activity, increased accessibility, increased flexibility of the active site, increased stability, broader and/or changed substrate specificity, and combinations thereof.
