This is an interventional treatment trial for Hypercholesterolemia Read More

Inclusion Criteria:

• Subjects must be >=18 years and <=75 years of age, male or female.
• Primary hypercholesterolemic subject with a plasma LDL cholesterol concentration >3.64 mmol/L (140 mg/dL) to <=6.3 mmol/L (250 mg/dL) using the Friedewald calculation; total cholesterol (TC) >5.2 mmol/L (200 mg/dL) to <12.7 mmol/L (500 mg/dL) and triglyceride concentrations of <=3.99 mmol/L (350 mg/dL) should be met at the same time. At the time of recruitment (Visit 1), these values may be lower if the subject is on lipid-lowering therapy. (ie, prior to the start of lipid lowering drug washout) or may be higher at the start of dietary therapy.
• Liver transaminases (ALT, AST) <=50% above the upper limit of normal, with no active liver disease and CK <=50% above the upper limit of normal.
• Clinical laboratory tests (complete blood count [CBC], blood chemistries, urinalysis) must be within normal limits, or clinically acceptable to the investigator/sponsor.
• Women of childbearing potential (includes women who are less than 1 year postmenopausal and women who become sexually active) must be using an acceptable method of birth control.
• Subjects must be free of any clinically significant diseases other than hyperlipidemia that would interfere with study evaluations.
• Subjects must understand and be able to adhere to the dosing and visit schedules.
• Subject must agree to remain on a cholesterol-lowering diet for the duration of the study (according to China Adult Treatment Panel of High Blood Cholesterol).

Exclusion Criteria:

• Subjects whose body mass index (BMI=weight [kg]/height2 [m]) is >=30 kg/m2 at Visit 3 (Baseline Visit).
• Subjects who have known hypersensitivity to HMG CoA reductase inhibitors.
• Subjects who consume >14 alcoholic drinks per week. (A drink is: a can of beer, glass of wine, or single measure of spirits).
• Any condition or situation, which in the opinion of the investigator, might pose a risk to the subject or interfere with participation in the study.
• Women who are pregnant or nursing.
• Subjects who have not observed the designated washout periods for any of the prohibited medications.
• Congestive heart failure defined by NYHA as Class III or IV.
• Uncontrolled cardiac arrhythmia.
• Myocardial infarction, coronary bypass surgery, or angioplasty within 6 months of study entry.
• Unstable or severe peripheral artery disease within 3 months of study entry.
• Unstable angina pectoris within 6 months of study entry.
• Uncontrolled hypertension (treated or untreated) with systolic blood pressure >160 mm Hg or diastolic >100 mm Hg at study entry.
• Uncontrolled (as determined by fasting glucose >180 mg/mL or HbA1c >9%) or newly diagnosed (within 1 month of study entry) diabetes mellitus.
• Uncontrolled endocrine or metabolic disease known to influence serum lipids or lipoproteins, ie, secondary causes of hyperlipidemia, such as secondary hypercholesterolemia due to hypothyroidism (thyroid stimulating hormone [TSH] above upper limit of normal). Subjects with a history of hypothyroidism who are on a stable therapy of thyroid hormone replacement for at least 6 weeks are eligible for enrollment if TSH levels are within normal limits before enrollment.
• Known impaired renal function (plasma creatinine >2.0 mg/dL), or nephrotic syndrome at study entry.
• Disorders of the hematologic, digestive, or central nervous systems, including cerebrovascular disease and degenerative disease that would limit study evaluation or participation.
• Known HIV positive.
• Cancer within the past 5 years (except for successfully treated basal and squamous cell carcinomas).
• History of mental instability, drug/alcohol abuse within the past 5 years, or major psychiatric illness not adequately controlled and stable on pharmacotherapy.
• Female subject receiving hormonal therapy, including hormone replacement, any estrogen antagonist/agonist, or oral contraceptives.
