Overview

A prospective, multicenter, open-label, randomized controlled study to assess the effects of early intensive lipid-lowering initiated before endovascular treatment setting on (i) functional outcome in patients with acute ischemic stroke between preoperative intensive lipid-lowering therapy with PCSK9 inhibitor (PCSK9i) and guideline-recommended standard of care (SoC)(ii) safety in these patients.

Eligibility

Inclusion Criteria:

• Adults (age 18 years and older);
• Imaging diagnosis of acute ischemic stroke with anterior circulation large vessel occlusion (including: internal carotid artery, middle cerebral artery M1 and M2, anterior cerebral artery A1 and A2);
• Planned to undergo endovascular intervention within 24 hours of symptom onset (or last known well time) according to local guidelines;
• Provision of informed consent by the patient or his/her legally authorized representative (or by an appropriate agent according to local requirements).

Exclusion Criteria:

• ASPECTS score ≤5 on cranial CT imaging;
• Pre-existing functional impairment, with mRS score \>2;
• Patients who are allergic to PCSK9 inhibitors;
• Patients who have received PCSK9 monoclonal antibody within 1 month prior to enrollment or PCSK9 siRNA therapy within 6 months prior to enrollment;
• Severe renal insufficiency, defined as estimated glomerular filtration rate (eGFR) \< 15 mL/min/1.73m2 at final screening;
• Active liver disease or hepatic dysfunction, defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \> 3 times the upper limit of normal;
• Severe, concomitant non-cardiovascular disease expected to reduce life expectancy to less than 3 months;
• Pregnant or lactating women;
• Patients who are participating in other clinical trials;
• Other conditions deemed unsuitable for inclusion in the clinical study by the investigator.
