  • Patent number: 8580252
    Abstract: The invention relates to the discovery of novel soluble neutral active Hyaluronidase Glycoproteins (sHASEGPs), methods of manufacture, and their use to facilitate administration of other molecules or to alleviate glycosaminoglycan associated pathologies. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described that include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain. Included are modified amino-terminal leader peptides that enhance secretion of sHASEGP. The invention further comprises sialated and pegylated form of a recombinant sHASEGP to enhance stability and serum pharmacokinetics over naturally occurring slaughterhouse enzymes. Further described are suitable formulations of a substantially purified recombinant sHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity.

  • Publication number: 20120108455
    Abstract: Methods for evolving or selecting or producing therapeutic proteins that exhibit reduced adverse side-effects and the resulting proteins are provided. For example, provided herein is an in vitro assay to identify conditionally active therapeutic proteins that exhibit better activity within one in vivo environment compared to another in vivo environment. The methods include the steps of a) testing the activity of a protein under conditions in which normal or increased activity is desired; b) testing the activity of the protein under conditions in which reduced activity compared to normal is desired; and c) comparing the activity in a) with b) and selecting/identifying a protein that has greater activity in a) compared to b). The selected/identified protein is a conditionally active protein.
