Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 75 who have been diagnosed with acute ischemic stroke and are not suitable for thrombolysis or mechanical thrombectomy.

Probably not a fit

Patients with a history of cerebral hemorrhage, severe hypertension, or contraindications to sodium valproate will not benefit from this study.

What this trial studies

This pilot trial aims to evaluate the feasibility, safety, and efficacy of sodium valproate in patients suffering from acute ischemic stroke. The study will investigate whether sodium valproate can enhance peripheral anti-inflammatory CD177+ neutrophil levels, which may contribute to its neuroprotective effects. Participants will be treated with sodium valproate or normal saline within 24 hours of stroke onset, and the study will help inform the design of future larger trials. The research is significant due to the limited effective treatment options currently available for ischemic stroke.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with acute ischemic stroke.

How similar studies have gone: While sodium valproate has shown potential neuroprotective effects in preclinical studies, this approach is novel in the context of acute ischemic stroke treatment.
