Phase III Study To Evaluate Alirocumab in Patients With Hypercholesterolemia Not Treated With a Statin (ODYSSEY CHOICE II)

A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study Evaluating the Efficacy and Safety of Alirocumab in Patients With Primary Hypercholesterolemia Not Treated With a Statin

Primary Objective:

To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by a regimen of Alirocumab including a starting dose of 150 mg every 4 weeks (Q4W) as add-on to non-statin lipid modifying background therapy or as monotherapy in comparison with placebo in participants with primary hypercholesterolemia not treated with a statin.

Secondary Objective:

• To evaluate the effects on other lipid parameters of Alirocumab 150 mg Q4W versus placebo.
• To evaluate the safety and tolerability of Alirocumab 150 mg Q4W.

Alirocumab 75 mg Q2W was added as a calibrator arm.

The core study duration was approximately 35 weeks per participant (screening: 3 weeks, double-blind treatment period: 24 weeks; follow-up: 8 weeks). Participants who successfully completed the treatment period had the possibility to participate in an optional open-label treatment period with Alirocumab 150 mg Q4W until second quarter 2017 or until the drug is commercially available in the country, whatever occurred first.

Inclusion criteria:

Participants with primary hypercholesterolemia (heterozygous familial hypercholesterolemia [heFH] or non-FH) not adequately controlled with their non-statin LMT (either ezetimibe or fenofibrate) or diet alone.

Exclusion criteria:

• LDL-C <70 mg/dL (1.81 mmol/L) at screening for statin intolerant participants at very high cardiovascular (CV) risk;
• LDL-C <100 mg/dL (<2.59 mmol/L) at screening for statin intolerant participants at high or moderate CV risk or, participants not fulfilling the statin intolerant definition at moderate CV risk;
• LDL-C ≥160 mg/dL (≥4.1 mmol/L) at screening for participants receiving diet only or, participants not fulfilling the statin intolerant definition at moderate CV risk and receiving a non-statin LMT.
