Evaluation of Alirocumab Versus Ezetimibe on Top of Statin in Asia in High Cardiovascular Risk Patients With Hypercholesterolemia

A Randomized, Double-blind, Parallel Group Study to Evaluate the Efficacy and Safety of Alirocumab (SAR236553/REGN727) Versus Ezetimibe in Asia in High Cardiovascular Risk Patients With Hypercholesterolemia Not Adequately Controlled With Their Statin Therapy

Primary Objective:

To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab as add-on therapy to stable maximally tolerated daily statin therapy in comparison to ezetimibe 10 mg daily after 24 weeks of treatment in Asia in participants with hypercholesterolemia at high cardiovascular (CV) risk.

Secondary Objectives:

• To evaluate the effect of alirocumab 75 mg in comparison with ezetimibe 10 mg on LDL-C after 12 weeks of treatment.
• To evaluate the effect of alirocumab on other lipid parameters: e.g., apolipoprotein B (Apo B), non-high density lipoprotein cholesterol (non-HDL-C), total cholesterol (TC), lipoprotein a (Lp[a]), HDL-C, triglycerides (TG), apolipoprotein A-1 (Apo A-1).
• To evaluate the safety and tolerability of alirocumab.
• To evaluate the development of anti-alirocumab antibodies.
• To evaluate the pharmacokinetics (PK) of alirocumab.

The maximum study duration was 35 weeks per participant, which included a screening period of up to 3 weeks, a 24-week randomized treatment period, and an 8-week post-treatment follow-up period.

Inclusion criteria:

Participants with hypercholesterolemia and established coronary heart disease (CHD) or CHD risk equivalents who are not adequately controlled with a maximally tolerated daily dose of statin at a stable dose for at least 4 weeks prior to the screening visit (Week -3).

Exclusion criteria:

• Participants without established CHD or CHD risk equivalents.
• LDL-C <70 mg/dL (<1.81 mmol/L) at the screening visit (Week -3) in participants with history of documented CV disease.
• LDL-C <100 mg/dL (<2.59 mmol/L) at the screening visit (Week -3) in participants without history of documented CV disease.
• Change in statin dose or dose regimen from screening to randomization.
• Currently taking a statin other than atorvastatin, rosuvastatin, or simvastatin.
• Atorvastatin, rosuvastatin, or simvastatin was not taken daily or not taken at a registered dose.
• Daily doses above atorvastatin 80 mg, rosuvastatin 40 mg, or simvastatin 40 mg.
• Use of cholesterol absorption inhibitor (ie, ezetimibe), omega-3 fatty acid (at doses ≥1000 mg daily), nicotinic acid, fibrates, bile acid-binding sequestrant, or red yeast rice products in the past 4 weeks prior to screening visit (Week -3).
• Fasting serum triglycerides >400 mg/dL (>4.52 mmol/L) at the screening period.
