Evaluation of Efficacy and Safety of AVE5530 Co-administered With Atorvastatin in Primary Hypercholesterolemia

Phase 3

Terminated

Brief Summary: The present study is assessing the efficacy and safety of AVE5530 (25mg and 50mg) co-administered with all approved doses of atorvastatin in a double-blind comparison with placebo, AVE5530 alone and atorvastatin alone in the management of patients with primary hypercholesterolemia. The main objective is to evaluate the effects of the association AVE5530+atorvastatin on LDL-C level reduction after 12 weeks of treatment. The effects of AVE5530+atorvastatin on other lipid parameters will be assessed as secondary objectives

Detailed Description: The study will include a 2 week pre-randomization placebo lead-in phase. There will be a 12- week double-blind treatment period for both components AVE5530 and atorvastatin, followed by a 40-week period with maintenance of double-blind design for AVE5530 component and open label for atorvastatin component transitioning at 20 mg for all patients with subsequent titration, if necessary, based on regular LDL-cholesterol monitoring. The treatment period can be variably extended up to approximately 18 months with double-blind for AVE5530 component and open-label for atorvastatin.

Recruitment & Eligibility

Inclusion Criteria

Adults with high cholesterol levels either not receiving or willing and able to discontinue ongoing lipid-lowering therapy

Exclusion Criteria

LDL-C levels > 250 mg/dL (6.48 mmol/L)
Triglycerides levels > 350mg/dL (3.95 mmol/L)
Conditions / situations such as:
- presence of any clinically significant uncontrolled endocrine disease known to influence lipids levels
- Active liver disease
- High estimated risk of Coronary Heart Disease
- Recent history of congestive heart failure , of unstable angina pectoris, myocardial infarction, coronary bypass surgery or angioplasty, or Unstable or severe peripheral artery disease

Women of childbearing potential not protected by effective contraceptive method of birth control (including oral contraceptives) and/or who are unwilling or unable to be tested for pregnancy prior to exposure to the Investigational Product
Hypersensitivity to any component of atorvastatin
Concurrent administration of Cytochrome P450 3A4 inhibitors (e.g. cyclosporine, erythromycin, clarithromycin, and azole antifungals) should be avoided as increasing the risk of myopathy with atorvastatin
