A Multi-Center Study of a SCD for Immunomodulatory Dysregulation in Pediatric AKI

Overview

The SCD PED-02 trial is examining the safety and efficacy of the Selective Cytopheretic Device (SCD) in treating pediatric acute kidney injury (AKI). AKI promotes a systemic inflammatory response syndrome (SIRS) which results in systemic microvascular damage and, if severe, multi-organ dysfunction. Activated circulating leukocytes play a central role in this process. The SCD is a synthetic membrane with the ability to bind activated leukocytes and, when used in a continuous renal replacement therapy (CRRT) extracorporeal circuit in the presence of regional citrate anticoagulation, modulates inflammation. The SCD PED-02 study will test the primary hypothesis that up to ten sequential 24-hour SCD treatments in pediatric patients with AKI will be completed safely and improve survival compared to historical controls who received CRRT alone.

The SCD PED-02 trial is examining the safety and efficacy of the Selective Cytopheretic Device (SCD) in treating pediatric acute kidney injury (AKI). Importantly, acute kidney injury is a highly lethal condition in critically ill patients. Despite improvements in acute medical care and advances in dialysis therapies, the mortality rate during the past four decades of this condition has not improved. Critically ill patients with AKI in hospital ICU settings have mortality rates of approximately 50%, including pediatric patients. AKI promotes a systemic inflammatory response syndrome (SIRS) which results in systemic microvascular damage and, if severe, multi-organ dysfunction. Activated circulating leukocytes play a central role in this process. Leukocytes, especially neutrophils, are major contributors to the pathogenesis and progression of many inflammatory disorders, including SIRS, sepsis, ischemia reperfusion injury, and acute respiratory distress syndrome (ARDS). Many therapeutic approaches are under investigation to limit the activation and tissue accumulation of leukocytes at sites of inflammation to minimize tissue destruction and disease progression. The SCD is comprised of tubing, connectors, and a synthetic membrane cartridge. The device is connected in series to a commercially available Continuous Renal Replacement Therapy (CRRT) device. Blood from the CRRT circuit is diverted after the CRRT hemofilter through to the extra capillary space (ECS) of the SCD. Blood circulates through this space and it is returned to the patient via the venous return line of the CRRT circuit. Regional citrate anticoagulation is used for the entire CRRT and SCD blood circuits. The SCD is a synthetic membrane with the ability to bind activated leukocytes and, when used in a continuous renal replacement therapy (CRRT) extracorporeal circuit in the presence of regional citrate anticoagulation, modulates inflammation. The SCD PED-02 study will test the primary hypothesis that up to ten sequential 24-hour SCD treatments in pediatric patients with AKI will be completed safely and improve survival compared to historical controls who received CRRT alone.
