Title:	Use of SERP-1 as an antiplatelet agent
Abstract:	Compositions and methods for antiplatelet/anti-thrombotic therapy in a mammalian subject are provided. The method involves administering a therapeutically effective amount of SERP-1 admixed with a pharmaceutically acceptable carrier to a subject in need of such therapy. Methods of administering SERP-1 with at least one other antiplatelet agent are also provided. The compositions and methods of the present invention are useful for treating and preventing recurrence of numerous cardiovascular diseases and injuries.
Inventor(s):	Lucas; Alexandra (London, ON, CA)
Assignee:	Viron Therapeutics, Inc. (London, Ontario, CA)
Application Number:	11/256,257
Patent Claims:	1. A method of inhibiting platelet activation in a mammalian subject, comprising administering a therapeutically effective amount of serine proteinase inhibitor-1 (SERP-1, SERP-1 analog, or biologically active fragment thereof and a pharmaceutically acceptable carrier to said subject, wherein said SERP-1 analog, or biologically active fragment thereof inhibits thrombolytic proteases urokinase-type plasminogen activator, tissue-type plasminogen activator, and plasmin in vitro. 2. A method of inhibiting platelet aggregation in a mammalian subject, comprising administering a therapeutically effective amount of serine proteinase inhibitor-1 (SERP-1), SERF-1 analog, or biologically active fragment thereof and a pharmaceutically acceptable carrier to said subject, wherein said SERF-1 analog, or biologically active fragment thereof inhibits thrombolytic proteases urokinase- type plasminogen activator, tissue-type plasminogen activator, and plasmin in vitro. 3. A method of inhibiting thrombus formation in a mammalian subject comprising administering a therapeutically effective amount of seine proteinase inhibitor-1 (SERP-1), SERP-1 analog, or biologically active fragment thereof and a pharmaceutically acceptable carrier to said subject, wherein said SERP-1 analog, or biologically active fragment thereof inhibits thrombolytic proteases urokinase- type plasminogen activator, tissue-type plasminogen activator, and plasmin in vitro. 4. The method of any one of claims 1, 2, or 3, wherein said mammalian subject is human. 5. The method of any one of claims 1,2, or 3, wherein said SERP-1, SERP-1 analog or biologically active fragment thereof, is delivered by oral administration, intravenous, intra-arterial, intra-articular, subcutaneous, intraperitoneal, intraspinal, intrarectal, or intramuscular infusion or aerosol inhalant.
