Clinical Trial Summary

Bleeding is a significant complication in cardiac surgery, with 10-15% of open cardiac surgery patients experiencing major intra- or post-operative bleeding. To address this unmet need, PLAS-FREE 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 bleeding in patients undergoing plasma transfusions.

Clinical Trial Description

Bleeding is a significant complication in cardiac surgery, with 10-15% of open cardiac surgery patients experiencing major intra- or post-operative bleeding. Bleeding complications are associated with worse clinical outcomes, including a higher risk of infection, ischemic events attributable to hypo-perfusion (e.g., myocardial infarction, acute kidney injury), in-hospital mortality, and transfusion-related adverse events. Additionally, bleeding complications are an important driver of blood product utilization in cardiac surgery. Coagulopathy and bleeding after cardiac surgery are often a multifactorial problem, thus there is unmet need to find new technologies that can give better care to these bleeding patients. In 2016, it was estimated that one million people throughout the world undergo cardiac surgery each year. Most of these surgeries are Coronary artery bypass grafting and valves replacement. Coronary artery bypass grafting (CABG) is still the most commonly performed cardiac surgery procedure worldwide, representing annual volumes of approximately 200,000 isolated cases in the US and an average incidence rate of 62 per 100,000 inhabitants in western European countries. Aortic valve replacement is procedure that treat diseases affecting the aortic valve, one of four valves that control blood flow through the heart. In the United States, it is estimated that 2.5% of the general population, 8.5% of those 65-74 years of age and 13.2% of those ≥75 years of age have moderate to severe valvular diseases. These surgeries are commonly done in the western countries, however, the ability to halt the bleed remain challenge for most clinicians. Failed or delayed treatment of a massive bleeding can result in irreversible end-organ damage (e.g., renal failure), cardiovascular events (e.g., stroke, myocardial injury) or death, accompanied by significantly increased costs.

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.

PLAS-FREE 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 bleeding in patients undergoing plasma transfusions. ;
