Primary Objective:

To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab SAR236553 (REGN727) as add-on therapy to stable maximally tolerated daily statin therapy with or without other lipid-modifying therapy (LMT) in comparison with placebo after 24 weeks of treatment in high cardiovascular (CV) risk patients with hypercholesterolemia.

Secondary Objectives:

  • To evaluate the effect of alirocumab SAR236553 (REGN727) in comparison with placebo on LDL-C at other time points.
  • To evaluate the effect of alirocumab SAR236553 (REGN727) on other lipid parameters.
  • To evaluate the safety and tolerability of alirocumab SAR236553 (REGN727).

Detailed Description:

The maximum study duration will be 63 weeks per patient, including a 3 week screening period, 52 week randomized treatment period, and 8 week follow-up period.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion criteria:

Patients with hypercholesterolemia and established coronary heart disease (CHD) or CHD risk equivalents who are not adequately controlled with a maximally tolerated daily dose of statin with or without other LMT, both at stable dose for at least 4 weeks to 6 weeks prior to screening (Week -2).

Exclusion criteria:

  • Age < 18 or legal age of adulthood, whichever is greater.
  • Patients without established CHD or CHD risk equivalent.
  • LDL-C <70 mg/dL (<1.81 mmol/L) and patients with a history of documented cardiovascular disease.
  • LDL-C <100 mg/dL (<2.59 mmol/L) and patients without a history of documented cardiovascular disease.
  • Not on a stable dose of LMT (including statin) for at least 4 Weeks and/or fenofibrate for at least 6 weeks, as applicable, prior to the screening visit (Week -2) and from screening to randomization.
  • Fasting serum triglycerides >400 mg/dL (>4.52 mmol/L).
