About this trial
This study is a prospective, multicenter, double-blind, randomized, placebo-controlled clinical trial designed to evaluate whether early administration of PCSK9 inhibitors can effectively improve functional outcomes at 90 days in patients with ischemic stroke (AIS) associated with intracranial atherosclerotic stenosis (ICAS), primarily assessed using the modified Rankin Scale at 90 days.
Eligibility criteria
Qualifiers
Age 30 to 80 years, inclusive.
Acute ischemic stroke with symptom onset within 72 hours before screening, diagnosed on the basis of neurological deficits and CT or MRI findings.
National Institutes of Health Stroke Scale (NIHSS) score of 4 to 25 at hospital admission.
CTA, DSA, or MRA evidence that the culprit intracranial artery has atherosclerotic stenosis of 50% to 99%.
Disqualifiers
Intracranial arterial stenosis attributable to a nonatherosclerotic cause, such as arterial dissection, moyamoya disease, or systemic vasculitis.
Any definite source of cardioembolism, such as atrial fibrillation, a mechanical prosthetic heart valve, left ventricular thrombus, or patent foramen ovale.
Clinical and imaging findings suggesting that the index ischemic event is primarily attributable to cerebral small vessel disease.
Pre-stroke disability, defined as a modified Rankin Scale score of 2 or higher before the index ischemic event.
