About this trial
This is an interventional treatment trial for Hypercholesterolemia
Eligibility Criteria
Inclusion Criteria:
- Adult African-American or Black subjects with diagnosis of primary hypercholesterolemia with plasma LDL-C >=145 mg/dL and <=250 mg/dL, and plasma TG <=350 mg/dL
- Postmenopausal women who are receiving postmenopausal hormonal therapy or raloxifene must be maintained on a stable HRT or raloxifene regimen for at least 6 weeks and throughout the study
- Female subjects of non-childbearing potential
- Willingness to give written consent, participate and complete all study-related procedures, and ability to follow a stable NCEP Step I (or stricter) diet regimen and keep a diet diary when required.
- Clinical laboratory tests (CBC, blood chemistries, and urinalysis) within normal limits (except as noted below) or clinically acceptable.
- ALT (SGPT) and AST (SGOT) concentrations <=2 times the upper limit of normal (ULN) and creatine phosphokinase <=2 times the ULN.
Exclusion Criteria:
- Pregnancy or any other situation, condition, or illness that, in the opinion of the investigator, may interfere with optimal participation in the study
- Secondary forms of hyperlipidemia or underlying disease likely to limit life span to less than one year
- Known hypersensitivity or any contraindication to simvastatin or ezetimibe
- Use of investigational drugs within 30 days of study entry
- Concomitant illnesses: congestive heart failure NYHA Class III or IV; obstructive cardiomyopathy; uncontrolled cardiac arrhythmias; severe aortic stenosis; MI, CABG or angioplasty within 3 months of study; unstable or severe peripheral artery disease; unstable angina pectoris; study-limiting disorders of the hematologic, digestive or central nervous systems including cerebrovascular disease and degenerative disease; uncontrolled or newly diagnosed diabetes mellitus; uncontrolled endocrine or metabolic disease known to influence serum lipids or lipoproteins (clinically euthyroid subjects on stable replacement doses of thyroid hormone are eligible for enrollment); uncontrolled hypertension; known impairment of renal function (plasma creatinine >2.0 mg/dL), dysproteinemia, nephrotic syndrome or other renal disease (24-hour urinary protein 3+ or 1 gram); hepatobiliary or hepatic disease (AST or ALT >2 times the upper limit of the reference range); HIV positive; known coagulopathy.

5. Study Description
Brief Summary
The purpose of this study is to evaluate whether coadministration of ezetimibe 10 mg/day with simvastatin 20 mg/day for 12 weeks will result in greater reduction of LDL-C, total cholesterol (TC), triglycerides (TG), non HDL-C, and apolipoprotein B (ApoB), and greater increase in HDL-C, compared with simvastatin 20 mg/day as monotherapy for 12 weeks in African-American subjects with primary hypercholesterolemia. This study is being performed to better define the efficacy of ezetimibe coadministered with simvastatin in this population.
