  Purpose
The purpose of this study is to determine whether treatment of Rosuvastatin (CRESTOR™) or Simvastatin given as monotherapy or given in combination with Ezetimibe, will lower the Low Density Lipoprotein Cholesterol (LDL-C) in patients with Hypercholesterolaemia and Coronary Heart Disease (CHD) or a CHD Risk Equivalent, Atherosclerosis or a 10-year CHD Risk of >20%

Condition Intervention Phase
Hypercholesterolemia Coronary Heart Disease Atherosclerosis Drug: Rosuvastatin (Crestor) Drug: Ezetimibe Drug: Simvastatin Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A 12-week Open-label, Randomised, Parallel-group, Multicentre, Phase IIIb Study to Compare the Efficacy and Safety of Rosuvastatin (CRESTOR™) in Combination With Ezetimibe and Simvastatin in Patients With Hypercholesterolaemia and CHD

Primary Outcome Measures:
  • Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in LDL-C = (Combination treatment value - Baseline value)/Baseline value*100


Secondary Outcome Measures:
  • Percent Change in High-density Lipoprotein Cholesterol (HDL-C) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in HDL-C = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Total Cholesterol (TC) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in TC = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Triglycerides (TG) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in TG = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Non-high-density Lipoprotein Cholesterol (nonHDL-C) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in nonHDL-C = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Apolipoprotein B (ApoB) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in ApoB = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Apolipoprotein A1 (ApoA-1) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in ApoA-1 = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in TC/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in TC/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in LDL-C/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in LDL-C/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in Non-HDL-C/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in non-HDL-C/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in ApoB/ApoA-1 After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in ApoB/ApoA-1 = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in High-sensitivity C-reactive Protein (Hs-CRP) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ]
    Percent change in hs-CRP = (Combination treatment value - Baseline value)/Baseline value*100

  • Percent Change in LDL-C After 6 Weeks Monotherapy [ Time Frame: Mean of Weeks 4 and 6 on monotherapy (Last observation carried forward) ]
    Percent change in LDL-C = (Monotherapy treatment value - Baseline value)/Baseline value*100

Criteria

Inclusion Criteria:
