Methods and pharmaceutical compositions for treating ischemic injury are provided. The methods include administering a therapeutically effective amount of a vascular matrix metalloproteinase 9 (MMP-9) inhibitor that reduces ischemic injury in a subject.

Chromatographic processes and systems for purifying a botulinum toxin from an APF fermentation medium.

A method is provided of decreasing or increasing the activity of a Pappalysin polypeptide by decreasing or increasing the level of interacting Pappalysin and stanniocalcin polypeptides. A method is also provided of preventing, treating or ameliorating a clinical condition in a mammalian subject, such as a human being, said method comprising administering to said mammalian subject, such as human being an effective amount of a stanniocalcin polypeptide. Moreover, a method is provided of preventing, treating or ameliorating a clinical condition in a mammalian subject, such as a human being, said method comprising administering to said mammalian subject, such as human being an effective amount of an agent capable of antagonizing interaction of a stanniocalcin polypeptide with a Pappalysin polypeptide.

The present invention is directed to compositions and methods for preventing and/or treating diseases and disorders of patients caused by non-Staphylococcal microorganisms. In particular, compositions and methods contain lysostaphin, altered forms of lysostaphin as compared to wild-type, and synergistic combinations of lysostaphin plus additional conventional treatments such as other enzyme, antibiotic and/or antibody treatment. The invention is also directed to detecting and identifying altered forms of lysostaphin that possess increased efficacy against infections as compared to wild-type lysostaphin, and forms that generate a minimal or no immune response in a patient. The invention is also directed to method of manufacturing lysostaphin and altered forms of lysostaphin, and compositions that direct the lysostaphin to the site of the infection such as aerosolized nanoparticles.

Provided herein are methods for purifying recombinant A Disintegrin-like and Metallopeptidase with Thrombospondin Type 1 Motif 13 (ADAMTS13) protein from a sample. The method comprises enriching for ADAMTS13 protein by chromatographically contacting the sample with hydroxyapatite under conditions that allow ADAMTS13 protein to appear in the eluate or supernatant from the hydroxylapatite. The methods may further comprise tandem chromatography with a mixed mode cation exchange/hydrophobic interaction resin that binds ADAMTS13 protein. Additional optional steps involve ultrafiltration/diafiltration, anion exchange chromatography, cation exchange chromatography, and viral inactivation. Also provided herein are methods for inactivating virus contaminants in protein samples, where the protein is immobilized on a support. Also provided herein are compositions of ADAMTS13 prepared according to said methods.

The invention relates to ADAMTS13 protein variants comprising residues 1 to 685 of ADAMTS13 and wherein one or more N-linked glycosylation sites are added as compared to wild-type ADAMTS13 and/or one or more existing N-linked glycosylation sites are shifted as compared to wild-type ADAMTS13. The invention further relates to compositions comprising such ADAMTS13 variants, methods for their preparation and uses thereof, in particular as an antithrombotic agent, and in the treatment of thrombotic disease, thrombotic microangiopathy, thrombotic thrombocytopenic purpura (TTP), hemolytic—uremic syndrome (HUS), ischemic stroke, systemic thrombosis, COVID19, antiphospholipid syndrome, pre-eclampsia/HELLP syndrome, sepsis and sickle cell disease.

The present invention relates to ADAMTS-13 mutants and/or variant/s that display resistance to tPA cleavage and/or inactivation. The present disclosure further provides fibrinolytic compounds, compositions, combined compositions and kits comprising the ADAMTS-13 mutants disclosed herein, as well as uses thereof for treating coagulation related disorders.

This invention relates to a pharmaceutical composition having thrombolytic activity comprising ADAMTS13, and to methods for treating or preventing a disorder associated with the formation and/or the presence of one or more thrombus and to methods of disintegrating one or more thrombus in a patient in need thereof. Furthermore, the invention relates to the use of a pharmaceutically effective amount of ADAMTS13 for the preparation of a pharmaceutical composition for treating or preventing a disorder associated with the formation or the presence of one or more thrombus and for disintegrating one or more thrombus in a patient in need thereof

This invention relates to methods of subcutaneous administration of ADAMTS13 formulations to a treat a disease or condition associated with ADAMTS13 and VWF dysfunction. Furthermore, evidence of the unexpectedly high bioavailability of ADAMTS13 formulations administered subcutaneously is provided herein.
