Acute Ischemic Stroke Clinical Trial
Official title:
Sodium Valproate in Patients With Acute Ischemic Stroke: a Pilot Randomized Trial
The purpose of this pilot trial is to investigate the feasibility, safety, and efficacy of sodium valproate in patients with acute ischemic stroke, and also explore the mechanism: whether valproate increases peripheral anti-inflammatory CD177+ neutrophil levels.
Ischemic stroke is one of the leading causes of disability and mortality worldwide, which imposes a huge burden on families and society. Currently, the effective treatment strategies of ischemic stroke are limited. It is of great clinical value and significance to explore effective neuroprotective medications besides reperfusion therapy. Sodium valproate is widely used in clinical practice, and its safety and tolerability has been confirmed. It is mainly used in the treatment of epilepsy, bipolar disorder, neuropathic pain and other diseases. In recent years, a number of preclinical studies have found that valproic acid has a potential neuroprotective effect in acute ischemic brain injury, which can decrease infarct volume, reduce blood-brain barrier damage, and improve neurological function. However, the neuroprotective mechanism of sodium valproate has not been fully revealed, and there is still a lack of clinical studies to clarify the neuroprotective effect of sodium valproate in patients with ischemic stroke. The goal of this study is to test whether sodium valproate could become a new therapeutic approach for ischemic stroke. This prospective pilot study is intended to investigate the feasibility, safety, and efficacy of sodium valproate in patients with acute ischemic stroke, thus support the estimate of sample size for a future full trial. In addition, we will test the hypotheses that valproate increases peripheral anti-inflammatory CD177+ neutrophil levels. Patients with acute ischemic stroke included in the study will be randomly assigned to sodium valproate group (20 mg/kg/d) or saline placebo group. Treatment will be started within 24 hours after stroke onset. The trial drug will be given intravenously for 3 consecutive days. The investigators evaluate whether sodium valproate can improve clinical outcomes and increase peripheral CD177+ neutrophil levels. ;
