Brief Summary:
Evaluate the proportion of hyperlipaemic persons with known coronary heart disease achieving ldl-c goal as defined by the national cholesterol education program (NCEP) adult treatment panel (ATP) III guidelines

Condition or disease Intervention/treatment Phase
Hypercholesterolemia Drug: simvastatin (+) ezetimibe Drug: Comparator: atorvastatin Phase 4

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 229 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Evaluate The Lipid-Lowering Efficacy and Safety of Vytorin in Comparison With Atorvastatin in Hypercholesterolaemic Patients With Coronary Artery Disease
Study Start Date : September 2006
Primary Completion Date : October 2008
Study Completion Date : October 2008

Arm Intervention/treatment
Experimental: 1 Drug: simvastatin (+) ezetimibe
simvastatin (+) ezetimibe 10/20mg, tablet, once daily, 12wks(sub group:24wks)
Other Names:
  • MK0653A
  • Vytorin®
Active Comparator: 2 Drug: Comparator: atorvastatin
atorvastatin 10mg, tablet, once daily, 12wks(sub group:24wks)
Other Name: Lipitor®

Primary Outcome Measures :
  1. Number of Participants Reaching the LDL-C (Low Density Lipoprotein-Cholesterol) Goal (< 100 mg/dl) After 6 Weeks of Treatment [ Time Frame: After 6 weeks of treatment ]
    Primary objective is to evaluate the proportion of patients achieving LDL-C target <100 mg/dl recommend in National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) after 6 weeks of treatment(vytorin 10/20 vs. atorvastatin 10 mg)

Secondary Outcome Measures :
  1. Number of Participants Reaching the LDL-C Goal (< 100 mg/dl) After 12 Weeks of Treatment [ Time Frame: After 12 weeks of the treatment ]
    If patients didn't achieve LDL-C <100 mg/dl after 6 weeks of treatment, they received the double dosage of study drug for the next 6 weeks (vytorin 10/40 or atorvastatin 20 mg) and If achieved LDL-C < 100 mg/dl, they received the same dosage of study drug for the next 6 weeks.
