Clinical Trial Summary

Hemodialysis is a therapy that filters waste, removes extra fluid and balances electrolytes. In hemodialysis, blood is removed from the body and filtered through a man-made membrane called a dialyzer, and then the filtered blood is returned to the body. Hemodialysis is associated with injury to the heart muscle called myocardial stunning. This may occur for many reasons, including removal of fluid during dialysis or low blood pressure. Initial ischemia and subsequent white blood cell infiltration into the injured myocardium play a critical role in the degree of myocardial ischemia reperfusion injury.

In this study an additional man made membrane (selective cytopheretic device) and tubing will be added to the dialysis circuit. The device shifts the circulating white blood cells pool to a less inflammatory phenotype. Researchers believe the selective cytopheretic device will alter the phenotype of circulating white blood cells which play a role in myocardial stunning.

The purpose of this study is to evaluate whether the selective cytopheretic device will reduce myocardial stunning events in hemodialysis patients. It will also report the rate of adverse events.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Regional Wall Abnormalities Identified on Echocardiogram	Regional wall motion will be scored using a standard wall motion scoring scheme. (1= normal; 2=hypokinetic; 3= akinetic; 4=dyskinetic). Scores will be tabulated for each of 16 predefined segments and a global wall motion score calculated as the sum of individual scores divided by the number visualized segments.	Baseline, 5 hour, 24 hours
Secondary	Number of Participants With an Adverse Event Based on the Clinical Laboratory Measurement: Ionized Calcium (iCa)	Number of participants who experienced a clinically significant change in systemic ionized calcium compared to reference range: 1.12 to 1.30.	Hour 1, hour 2, hour 3, hour 4, hour 5
Secondary	Number of Participants With an Adverse Event Based on the Clinical Laboratory Measurement: Hemoglobin	Number of participants who experienced a clinically significant change in hemoglobin who experience a change of more than 10% of baseline	Baseline, Hour 5, 24 hours
