About this trial

This is a prospective, multicenter, open-label, blinded-endpoint, randomized controlled trial designed to evaluate the efficacy and safety of PCSK9 inhibitor combined with statin therapy compared to statin monotherapy in reversing asymptomatic intracranial atherosclerosis, assessed using high-resolution magnetic resonance imaging of the intracranial vessel walls.

Eligibility criteria

Qualifiers

Age ≥18 and ≤80, male or female;

Asymptomatic intracranial artery stenosis (50%-99%) in the internal carotid artery (C6-7 segments), middle cerebral artery (M1 segment), vertebral artery (V4 segment), or basilar artery, confirmed by angiography (MRA, CTA, or DSA);

Atherosclerosis identified as the cause of intracranial artery stenosis by high-resolution magnetic resonance imaging;

No previous ischemic cerebrovascular events (including ischemic stroke or transient ischemic attack).

Disqualifiers

Non-atherosclerotic intracranial artery stenosis, including arterial dissection; moya moya disease; systemic vasculitis and primary central nervous system vasculitis; varicella-zoster vasculopathy or other viral vasculopathy; neurosyphilis and other intracranial infections, radiation vasculopathy; fibromuscular dysplasia, sickle cell disease, neurofibromatosis; reversible cerebral vasoconstriction syndrome; postpartum vasculopathy; suspected vasospasm, suspected reperfusion after vessel occlusion.

Upstream tandem extracranial vessel stenosis (≥50%) adjacent to the target intracranial stenotic vessel.

Previous treatment of target intracranial lesion with endovascular intervention or plan to perform endovascular intervention within 6 months, including intracranial stenting, endovascular angioplasty, and thrombectomy.

Any intracranial hemorrhage (parenchymal, subarachnoid, subdural, extradural, intraventricular) within 90 days prior to enrollment.
