Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who are scheduled for isolated coronary artery bypass grafting or valve replacement and require plasma transfusions.

Probably not a fit

Patients who are in a life-threatening condition, hemodynamically unstable, or have certain bleeding disorders like hemophilia will not benefit from this study.

What this trial studies

This clinical investigation evaluates the safety and effectiveness of ClearPlasma™, a medical device designed to filter plasma and reduce fibrinolysis in patients undergoing coronary artery bypass grafting or valve replacement. The study is a multi-center, international, double-blind, randomized controlled trial that aims to address the significant issue of bleeding complications in cardiac surgery, which affects a substantial percentage of patients. By utilizing plasminogen-depleted plasma, the study seeks to improve clinical outcomes and reduce the need for blood product utilization during and after surgery.

Why it matters

Potential benefit: If successful, this approach could significantly decrease bleeding complications and improve recovery outcomes for patients undergoing cardiac surgery.

How similar studies have gone: While the use of plasma filtration devices is a novel approach, similar studies addressing bleeding complications in cardiac surgery have shown promising results.
