Brief summary:
This is a randomized, double-blind, active-comparator, parallel-group study in patients at high cardiovascular risk with nonfamilial hypercholesterolemia or heterozygous familial hypercholesterolemia (heFH).

Detailed description:

Arms: arm 1: Participants, who were receiving atorvastatin 20 mg over-encapsulated tablets orally at baseline, received atorvastatin 40 mg over-encapsulated tablets orally once daily (QD), placebo for alirocumab SC injection every two weeks (Q2W), and placebo for ezetimibe over-encapsulated tablets orally QD added to stable Lipid-Modifying Therapy (LMT) for 24 weeks. arm 2: Participants, who were receiving atorvastatin 20 mg over-encapsulated tablets orally at baseline, received ezetimibe 10 mg over-encapsulated tablets orally QD, atorvastatin 20 mg over-encapsulated tablets orally QD, and placebo for alirocumab SC injection Q2W added to stable LMT for 24 weeks. arm 3: Participants, who were receiving atorvastatin 20 mg over-encapsulated tablets orally at baseline, received Alirocumab 75 mg SC injection Q2W, atorvastatin 20 mg over-encapsulated tablets orally QD, and placebo for ezetimibe over-encapsulated tablets 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 atorvastatin 40 mg over-encapsulated tablets orally at baseline, received Atorvastatin 80 mg over-encapsulated tablets orally QD, placebo for alirocumab SC injection Q2W, and placebo for ezetimibe over-encapsulated tablets orally QD added to stable LMT for 24 weeks. arm 5: Participants, who were receiving atorvastatin 40 mg over-encapsulated tablets orally at baseline, received rosuvastatin 40 mg over-encapsulated tablets orally QD, placebo for alirocumab SC injection Q2W, and placebo for ezetimibe over-encapsulated tablets orally QD added to stable LMT for 24 weeks. arm 6: Participants, who were receiving atorvastatin 40 mg over-encapsulated tablets orally at baseline, received ezetimibe 10 mg over-encapsulated tablets orally QD, atorvastatin 40 mg over-encapsulated tablets orally QD, and placebo for alirocumab SC injection Q2W added to stable LMT for 24 weeks. arm 7: Participants, who were receiving atorvastatin 40 mg over-encapsulated tablets orally at baseline, received alirocumab 75 mg SC injection Q2W, atorvastatin 40 mg over-encapsulated tablets orally QD, and placebo for ezetimibe over-encapsulated tablets 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.
