Early Endotoxin Burden Reduction With oXiris in Septic Shock Patients Requiring CRRT
Sponsor: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University
Summary
The goal of this clinical trial is to learn whether continuous renal replacement therapy (CRRT) using the oXiris filter can lower the amount of endotoxin in the blood of adults with septic shock who need CRRT. Septic shock is a life-threatening condition caused by infection and severe organ dysfunction. CRRT is a form of continuous blood purification used to support the kidneys and manage fluid and waste products. The oXiris filter is designed to provide CRRT while also removing endotoxin and inflammatory substances from the blood. The main questions this study aims to answer are: Does 24 hours of CRRT with the oXiris filter lower blood endotoxin levels compared with levels before treatment? What changes occur in inflammation, organ function, and the need for medicines that raise blood pressure? What medical problems or treatment-related complications occur during the study? This is a single-center study with no comparison group. About 13 participants will take part, and all participants will receive CRRT with the oXiris filter for a planned period of 24 hours. Other treatments for septic shock, including treatment for infection, fluids, medicines to support blood pressure, and other organ support, will be provided according to the hospital's usual care. Researchers will: Collect blood samples before and after the 24-hour oXiris treatment to measure endotoxin and markers of inflammation. Record blood pressure, blood lactate, circulation, organ function, use of blood pressure medicines, and CRRT treatment information. Continue selected blood tests and clinical assessments during the first 7 days Record any medical problems, including serious medical problems, during the study. Check whether participants are alive at 28 days and 90 days after enrollment The study may help researchers better understand the biological effects and safety of the oXiris filter and provide information for larger future studies.

oXiris Hemofilter
The oXiris hemofilter will be integrated into a continuous renal replacement therapy circuit using the Prismaflex system. Continuous venovenous hemofiltration will be performed for a planned duration of 24 hours. The prescribed effluent dose will be 25-30 mL/kg/hour, with a blood flow rate of 100-150 mL/min and a replacement fluid rate of 1,000-1,500 mL/hour. Regional citrate anticoagulation will be preferred unless contraindicated. The filter may be replaced earlier if clotting, increased transmembrane pressure, or other clinical or technical conditions require replacement. Treatment after the planned 24-hour study period will be determined by the treating clinicians according to the participant's clinical condition.
