  • Patent number: 9562223
    Abstract: Provided are methods for reducing intraocular pressure in the eye of a subject by administering neutral active soluble active hyaluronidase glycoproteins (sHASEGPs) and modified forms thereof to the eye. The sHASEGPs are soluble forms of human PH20 hyaluronidase. Also provided are the sHASEGPs, methods of manufacture, and uses thereof. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described. The sHASEGPs include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain.

  • Publication number: 20160220690
    Abstract: Provided herein are methods for ameliorating an adverse effect of systemic administration of a PEG hyaluronan degrading enzyme to a subject. The methods involve systemically administering a PEGylated hyaluronan degrading enzyme, particularly a PEGylated hyaluronidase, such as any of the animal or bacterial hyaluronidases, to the subject and administering an amount of a corticosteroid sufficient to ameliorate the adverse effect. Also provided are method of treating a hyaluronan-associated disease or condition for single-agent therapy or combination therapy.

  • Publication number: 20160051640
    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: 20140341875
    Abstract: The invention relates to the discovery of a novel Chondroitinase Glycoproteins (CHASEGPs), methods of manufacture, and potential uses in conditions where removal of chondroitin sulfates may be of therapeutic benefit. Chondroitinase Glycoproteins require both a substantial portion of the catalytic domain of the CHASEGP polypeptide and asparagine-linked glycosylation for optimal chondroitinase activity. The invention also includes carboxy-terminal deletion variants of CHASEGP that result in secreted variants of the protein to facilitate manufacture of a recombinant CHASEGP. Further described are suitable formulations of a substantially purified recombinant CHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity. CHASEGP is useful for the degradation of glycosaminoglycans and chondroitin sulfate proteoglycans under clinical conditions where their removal is of therapeutic value.

  • Publication number: 20140271609
    Abstract: Methods and combinations are provided for controlling the duration of action, in vivo, of matrix-degrading enzymes. The methods and combinations permit temporary in-vivo activation of matrix-degrading enzymes upon administration to the extra cellular matrix (or “ECM”). Matrix-degrading enzymes having a controlled duration of action can be used to treat ECM-mediated diseases or disorders characterized by increased deposition or accumulation of one or more ECM components.
