Therapeutic Thrombin Analogs

DESCRIPTION (provided by applicant): Project Summary/Abstract Treatment of acute ischemic stroke (AIS) with the thrombolytic/antithrombotic agent tissue plasminogen activator (tPA, Activase(R)) is limited due to the potential for severe hemorrhagic side effects. The first symptoms of acute ischemia to tPA treatment ( time to needle ) can span hours, even in developed urban areas, since an established diagnosis in a hospital setting is required before thrombolytic therapy. Consequently, there is a major unmet medical need for safe antithrombotic agents with no risk of bleeding that can be administered immediately as an emergency measure upon signs of acute cardio- and cerebrovascular events. To directly address this need, our company has been developing a novel antithrombotic agent for the safe treatment of AIS. The product candidate is a bioengineered recombinant selective protein C activator enzyme (PCA) that has potent antithrombotic effects without increasing hemorrhagic risks. Our proprietary PCA mol
