Overview
Brief Summary
Upper gastrointestinal hemorrhage (UGIH) is one of the most common gastrointestinal emergencies, and is associated with significant morbidity and mortality. Plas-Free aims to evaluate ClearPlasma safety in patients with UGIH.
Detailed Description
Upper gastrointestinal hemorrhage (UGIH) is one of the most common gastrointestinal emergencies, and is associated with significant morbidity and mortality. Acute upper gastrointestinal hemorrhage (AUGIH) management guidelines call for aggressive hemodynamic resuscitation, prevention and treatment of complications and treatment of bleeding, which generally includes endoscopic intervention and transfusion of appropriate blood components. However, in many cases, spontaneous hyperfibrinolysis occurs, jeopardizing pharmacological control of AUGIH. Antifibrinolytic drugs are considered effective in counteracting hyperfibrinolysis, but are associated with various side effects, such as neurotoxicity and accelerated fibrinolysis upon prolonged use. Fibrin clot breakdown is actively mediated by plasmin, a serine protease which cleaves fibrin. Administration of plasma depleted of plasminogen, the precursor of plasmin, may shift the balance towards coagulation. PlasFree Ltd. has developed ClearPlasma, a single-use, extracorporeal plasma filtration device which extracts plasminogen from plasma to reduce fibrinolysis. The resulting plasminogen-depleted plasma (PDP) is expected to reduce risk of fibrinolysis and re-bleeding in Patients undergoing plasma transfusions.
