Study to Evaluate the Efficacy and Safety of an Every Four Weeks Treatment Regimen of Alirocumab (REGN727/ SAR236553) in Patients With Primary Hypercholesterolemia (ODYSSEY CHOICE 1)

A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of an Every Four Weeks Treatment Regimen of Alirocumab in Patients With Primary Hypercholesterolemia

To determine the efficacy, long-term safety, and tolerability of alirocumab 300 mg every 4 weeks (Q4W), in comparison with placebo, as well as its potential as a starting regimen. The dose regimen of 75 mg every 2 weeks (Q2W), as used in other studies, was added as a calibrator.
