Clinical Trial Summary

The primary goal of the trial is to investigate whether the lipid lowering strategy using Alirocumab plus statin could cause more changes from baseline in intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up, in patients with recent stroke/transient ischemic attack (TIA) caused by intracranial artery stenosis.

Clinical Trial Description

Intracranial atherosclerosis stenosis (ICAS) is one of the most common causes of stroke worldwide and is particularly prevalent in Asian. It accounts for up to 30-50% of strokes amongst Asian patient cohorts, in contrast to 5-10% of strokes amongst western patient cohorts. The SAMMPRIS established aggressive medical management (Intensive lipid lowering with statin to reach a low-density lipoprotein (LDL)-cholesterol lower than 1.8mmol/L, et al) as a superior choice for symptomatic ICAS compared to the percutaneous transluminal angioplasty and stenting. However, around 15% still had recurrent stroke or death during a median follow-up of 32.4 months in SAMMPRIS study in the aggressive medical management group.

Alirocumab, a member of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, is a fully human monoclonal antibody that reduces LDL cholesterol levels by approximately 60%. The ODYSSEY OUTCOMES study showed that Alirocumab reduced the risk of cardiovascular events (e.g. cardiovascular death, myocardial infarction and stroke), in patients with atherosclerotic cardiovascular disease.

The proposed pilot study will recruit 50 patients with recent stroke/transient ischemic attack (TIA) caused by intracranial artery stenosis, and directly compare the differences before and after Alirocumab on top of statin therapy in changes of intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up. ;
