A Multicenter, Prospective, Randomized Controlled Trial to Evaluate the Efficacy of PCSK-9 Inhibitors in Delaying the Progression of Calcified Aortic Valve Disease

Early Phase 1

Not yet recruiting

• Conditions: Aortic Stenosis; PCSK9 Inhibitor; Calcified Aortic Valve Disease
• Interventions: Drug: The Group A received PCSK9 inhibitor plus statin therapy

• Registration Number: NCT06996223
• Lead Sponsor: Nanfang Hospital, Southern Medical University

Brief Summary

The aim of this clinical trial is to understand whether the drug PCSK9 inhibitor can slow the progression of calcific aortic valve disease and to understand the safety of the drug.

The primary objective of the study was to evaluate whether PCSK9 inhibitors could delay the progression of aortic stenosis in patients with aortic stenosis.

Secondary objectives: 1) To evaluate whether PCSK9 inhibitors can delay the progression of valve calcification in patients with aortic stenosis;2) To evaluate whether PCSK9 inhibitors can reduce long-term adverse events in patients with aortic stenosis;3) To evaluate the effect of PCSK9 inhibitors on circulating Lp(a) levels in patients with aortic stenosis.

Arm && Interventions

Group	Intervention	Description
Group A	The Group A received PCSK9 inhibitor plus statin therapy	Subjects randomized to the group A will be treated with a lipid-lowering regimen based on PCSK9 inhibitors (subcutaneous injection, twice a week) + statins (maximum tolerated dose). The study lasted for 4 years, and the patients were followed up at 1, 6, 12, 24, 36, and 48 months to assess the efficacy and safety of the drug administration and to collect information on relevant examinations and tests.
