Abstract: Compositions include highly concentrated Alpha-1 Proteinase Inhibitor (A1PI) in a concentration greater than or equal to 100 mg/ml. Pharmaceutical compositions can be prepared from these compositions. The pharmaceutical compositions can be suitable for subcutaneous administration. The highly concentrated A1PI solutions can be obtained by single-pass tangential flow filtration (SPTFF).

Abstract: A method for preparing a composition of human plasma-derived immunoglobulin M (IgM) includes PEG precipitation of the IgM, resuspension of the precipitated IgM; (c) performing an adsorption chromatography, removing isoagglutinins A/B, nanofiltration, and ultrafiltration/diafiltration. The precipitation can be performed at a pH between 4.5 and 6.5, and the PEG can be at a concentration between 5 (w/v) and 11% (w/v).

Abstract: Described herein are methods for purifying recombinant, cell culture derived alpha1-protease inhibitor and removing a colored species that co-purifies with the recA1PI protein. Also described are methods for reducing the iron in cell culture derived alpha1-protease inhibitor.

Abstract: The present invention provides a fibrinolytic composition useful as a therapeutic for administration to a patient having a thrombotic occlusion. In one aspect of the present invention, the fibrinolytic composition comprises a reversibly inactivated acidified serine protease substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent. In another aspect of the invention, the fibrinolytic composition of the present invention comprises a reversibly inactivated acidified plasmin substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent.

Abstract: Methods of thrombolysis that allow the use of a fibrinolytic composition comprising reversibly inactivated acidified plasmin and the localized delivery of the plasmin to a vascular thrombotic occlusion are disclosed. Further disclosed is a method for administering a therapeutic dose of a fibrinolytic composition substantially free of plasminogen activator to a human or animal having a vascular thrombotic occlusion. The fibrinolytic composition includes a reversibly inactivated acidified plasmin substantially free of plasminogen activator. Intravascular catheter delivery of the fibrinolytic composition directly into or in the immediate vicinity of the thrombus is disclosed to minimize the systemic degradation of fibrin while retaining the maximum plasmin activity against the thrombus.

Abstract: The invention provides an improved method of thrombolytic therapy by the direct admiistration of active plasmin to a clot site via catheter. An active, stable preparation of plasmin is provided, as is a process for activation and isolation of active plasmin.

Abstract: A method and device for activating and applying a solution of fibrinogen to form fibrin glue at a desired site. The method includes contacting the solution of fibrinogen with immobilized thrombin under conditions that result in a solution of polymerizable fibrin and delivering the activated solution to the desired site. The device includes a housing having a compartment for a solution of fibrinogen, a container for immobilized thrombin, a structure following the solution of fibrinogen to be brought into contact with the immobilized thrombin under conditions which permit the activation of the fibrinogen to polymerizable fibrin, and a structure allowing for delivery of the activated solution to the desired site.
