Efficacy and Safety Evaluation of Alirocumab in Patients With Heterozygous Familial Hypercholesterolemia or High Cardiovascular Risk Patients With Hypercholesterolemia on Lipid Modifying Therapy (ODYSSEY JAPAN)

A Randomized, Double-blind, Placebo-controlled, Parallel Group, Multicenter Study to Evaluate the Efficacy and Safety of Alirocumab in Heterozygous Familial Hypercholesterolemia or High Cardiovascular Risk Patients With Hypercholesterolemia Not Adequately Controlled With Their Lipid Modifying Therapy

Primary Objective:

To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab as add-on therapy to stable daily statin therapy with or without other lipid modifying therapy in comparison with placebo after 24 weeks of treatment in heterozygous familial hypercholesterolemia (HeFH) or high cardiovascular risk participants with hypercholesterolemia.

Secondary Objectives:

• To evaluate the effect of alirocumab in comparison with placebo on LDL-C after 12 weeks of treatment.
• To evaluate the effect of alirocumab on other lipid parameters.
• To evaluate the long-term effect of alirocumab in comparison with placebo on LDL-C after 52 weeks of treatment.
• To evaluate the safety and tolerability of alirocumab.
• To evaluate the development of anti-alirocumab antibodies.
• To evaluate the pharmacokinetics of alirocumab.

Total duration per participant of approximately 63 weeks (14 months) (screening: 3 weeks, double-blind treatment period: 52 weeks, and follow-up period: 8 weeks).

Inclusion criteria:

Participants with heterozygous familial hypercholesterolemia or non-familial hypercholesterolemia who were not adequately controlled with a stable daily dose of statin with or without other lipid modifying therapy, at stable dose prior to the screening visit (Week -3).

Exclusion criteria:

1. LDL-C <100 mg/dL (<2.59 mmol/L) at the screening visit in participants with heterozygous familial hypercholesterolemia or in participants with non-familial hypercholesterolemia who had a history of documented coronary heart disease as described in Japan Atherosclerosis Society (JAS) Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases 2012.
2. LDL-C <120 mg/dL (<3.10 mmol/L) at the screening visit in participants with non-familial hypercholesterolemia who had a history of documented diseases or other risk factors as categorized in primary prevention category III as described in JAS Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases 2012.
3. Not on a stable daily dose of lipid modifying therapy (including statin) within 4 weeks prior to the screening visit or between screening and randomization visits.
4. Age <20 years at the screening visit.
