Brief summary:
To evaluate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab (REGN727/SAR236553) as an add-on therapy to other LMT in patients with hypercholesterolemia at high cardiovascular (CV) risk.

Detailed description:

Arms:
arm 1: Participants, who were receiving rosuvastatin 10 mg over-encapsulated tablet orally at baseline, received rosuvastatin 20 mg over-encapsulated tablet orally once daily (QD), placebo for alirocumab SC injection every two weeks (Q2W), and placebo for ezetimibe over-encapsulated tablet orally QD added to stable Lipid-Modifying Therapy (LMT) for 24 weeks. arm 2: Participants, who were receiving rosuvastatin 10 mg over-encapsulated tablet orally at baseline, received ezetimibe 10 mg over-encapsulated tablet orally QD, rosuvastatin 10 mg over-encapsulated tablet orally QD, and placebo for alirocumab SC injection Q2W added to stable LMT for 24 weeks. arm 3: Participants, who were receiving rosuvastatin 10 mg over-encapsulated tablet orally at baseline, received alirocumab 75 mg SC injection Q2W, rosuvastatin 10 mg over-encapsulated tablet orally QD, and placebo for ezetimibe over-encapsulated tablet orally QD added to stable LMT for 24 weeks. Alirocumab dose up-titrated to 150 mg Q2W from Week 12 when LDL-C levels ≥70 mg/dL (1.81 mmol/L) or ≥100 mg/dL (2.59 mmol/L) at Week 8, based on baseline disease characteristic and medical history. arm 4: Participants, who were receiving rosuvastatin 20 mg over-encapsulated tablet orally at baseline, received rosuvastatin 40 mg over-encapsulated tablet orally QD, placebo for alirocumab Q2W SC injection, and placebo for ezetimibe QD over-encapsulated tablet orally added to stable LMT for 24 weeks. arm 5: Participants, who were receiving rosuvastatin 20 mg over-encapsulated tablet orally at baseline, received ezetimibe 10 mg over-encapsulated tablet orally QD, rosuvastatin 20 mg over-encapsulated tablet orally QD, and placebo for alirocumab Q2W SC injection added to stable LMT for 24 weeks. arm 6: Participants, who were receiving rosuvastatin 20 mg over-encapsulated tablet orally at baseline, received alirocumab 75 mg Q2W SC injection, rosuvastatin 20 mg over-encapsulated tablet orally QD, and placebo for ezetimibe over-encapsulated tablet orally QD added to stable LMT for 24 weeks. Alirocumab dose up-titrated to 150 mg Q2W from Week 12 when LDL-C levels ≥70 mg/dL (1.81 mmol/L) or ≥100 mg/dL (2.59 mmol/L) at Week 8, based on baseline disease characteristic and medical history.

Interventions: intervention 1: Alirocumab intervention 2: Rosuvastatin intervention 3: Ezetimibe intervention 4: Placebo
Intervention descriptions: intervention 1: Alirocumab administered as a SC injection of 1 mL into the abdomen, thigh, or outer area of the upper arm. intervention 2: Rosuvastatin over-encapsulated tablets orally. intervention 3: Ezetimibe over-encapsulated tablets orally. intervention 4: Placebo for alirocumab and ezetimibe.
