sICASBLM is a prospective controlled trial, to asses the impact of improving blood lipid management on clinical outcome of moderate to severe symptomatic intracranial atherosclerotic stenosis patients (LDL-C>1.8mmol/L) without endovascular therapy.


sICASBLM aims to determine the effectiveness of conventional lipid management combined with PCSK9 inhibitors compared to conventional lipid management (atorvastatin 20-40mg or rosuvastatin 10-20mg or simvastatin 20-40mg) in reducing the incidence of recurrent stroke in patients with moderate to severe symptomatic intracranial atherosclerotic stenosis (LDL-C>1.8mmol/L) without endovascular therapy.

Condition Intracranial Artery Stenosis
Treatment PCSK9 Inhibitor
