Reduction of SystemiC Inflammation After Ischemic Stroke by Intravenous DNase Administration (ReSCInD) (ReSCInD)
The goal of this (monocentric, randomised, placebo-controlled single-blinded; phase 2) clinical trial is to test the hypothesis that DNase 1 administration leads to a reduction in systemic immune response measured in patients after acute ischaemic stroke compared to control treatment.
Participants will receive intravenous DNase 1 (500 µg/kg) or placebo (NaCl 0.9%) twice within 24±6 hours after symptom onset (last seen well). Blood samples will be taken at baseline, day 1 and 3. Personal visits will occur on baseline, day 1, 3 and discharge date. A telephone interview will be conducted on day 30±3.
