Hemoadsorption for Severe Ischemic Stroke

First Affiliated Hospital of Wannan Medical College116 enrolled

Overview

This is a multicenter, randomized-controlled, open-label, blinded endpoint clinical trial that aims to evaluate the efficacy and safety of hemoadsorption for severe ischemic stroke

This is a multicenter, randomized-controlled, open-label, blinded endpoint clinical trial that aims to evaluate the efficacy and safety of hemoadsorption for severe ischemic stroke. During the study period, a total of 116 patients with severe ischemic stroke will be enrolled from 10 centers. To evaluate whether adjunctive hemoadsorption therapy combined with standard treatment can reduce the incidence of severe adverse functional outcomes (modified Rankin Scale \[mRS\] 4-6) at 90 days. Patients in control group will receive standard treatment, and those in the other group will receive standard treatment plus hemoadsorption therapy administered once on days 1, 3, and 5 following enrollment. Study visits will be performed on the day of randomization, at treatment period, at day 7, at day 14 or hospital discharge and at day 90. In addition to the primary endpoint, the study will evaluate whether hemoadsorption can reduce acute-phase inflammatory cytokine levels and decrease the incidence of complications including hemorrhagic transformation, malignant cerebral edema, and pulmonary infections in severe ischemic stroke patients.
