About

The objective of this study is to evaluate the effectiveness and safety of endovascular therapy combined with 25% human albumin in the treatment of acute large vessel occlusive stroke.

Full description

Stroke is the second leading cause of death worldwide, 85% of which are acute ischemic strokes (AIS). Neuronal death is the primary pathological manifestation of acute ischemic stroke (AIS). Preclinical studies have revealed that neuroprotective agents can reduce neuronal damage and improve neurological outcomes in experimental animals. However, over the past 40 years, clinical translation of neuroprotective drugs has consistently failed. In 2015, with the publication of five randomized controlled trials (RCTs) on thrombectomy for anterior circulation, there was sufficient evidence-based support for thrombectomy in large vessel occlusion of the anterior circulation, ushering us into a new era of AIS treatment - the era of efficient reperfusion therapy. In this context, neuroprotective therapy should be re-examined as an adjunctive approach to reperfusion therapy.

Albumin, the predominant plasma protein synthesized primarily in the liver, possesses various biochemical properties that are expected to confer a neuroprotective effect following acute ischemic stroke.

This study is a multi-center, randomized, double-blind, placebo-controlled clinical study, focusing on patients with acute large vessel occlusive stroke. It aims to investigate the effectiveness and safety of albumin as an adjunctive treatment to endovascular therapy compared with placebo in reducing infarct volume, improving long-term functional outcomes, and daily living activities of patients with acute ischemic stroke in the era of reperfusion therapy.

Inclusion criteria

Age between 18 and 80 years;
Anterior circulation acute ischemic stroke, with acute occlusion of the responsible vessel located in the intracranial segment of the internal carotid artery, or the M1 or M2 segment of the middle cerebral artery;
National Institute of Health Stroke Scale (NIHSS) score ≥6;
Modified Rankin Scale (mRS) score ≤1 before onset of the disease;
Alberta Stroke Program Early CT Score (ASPECTS) ≥3 points;
Ischemic-core volume ≤100ml;
Patient treatable within 24 hours of symptom onset. Symptoms onset is defined as point in time the patient was last seen well (at baseline) if patients are unable to provide a reliable history or the point in time when symptoms have started if patients can provide a reliable history. Treatment start is defined as groin puncture.;
Written informed consent provided by the patients or their legal relatives.
