Primary Outcome Measures:
  • Percent Change in Low-Density Lipoprotein - Cholesterol (LDL-C) Values [ Time Frame: End of Week 4 to Week 16 or discontinuation ] [ Designated as safety issue: No ]
    LDL-C was measured before group study drug administration (Week 4, end of atorvastatin single therapy) and at the end of study drug administration (after 12 weeks of study drug treatment, or at discontinuation).


Secondary Outcome Measures:
  • Percent Change in LDL-C [ Time Frame: End of washout period to Week 16 or discontinuation ] [ Designated as safety issue: No ]
    LDL-C was measured at the start of the atorvastatin 10 mg treatment period (end of the washout period) and at the end of administration of the study drug (Week 16 or discontinuation).

  • Number of Participants Whose LDL-C Levels Reached the Lipid Management Target Values [ Time Frame: Week 16 or discontinuation ] [ Designated as safety issue: No ]

    LDL-C was measured at the end of administration of the study drug (Week 16 or discontinuation).

    Target values:

    For participants with history of coronary artery disease: <100 mg/dL;

    for participants with at least 3 cardiovascular (CV) risk factors: <120 mg/dL;

    for participants with 1-2 CV risk factors: <140 mg/dL;

    for participants with no CV risk factors: <160 mg/dL.


  • Percent Change in Total Lipids and High Sensitivity C-reactive Protein (Hs-CRP) [ Time Frame: End of Week 4 to Week 16 or discontinuation ] [ Designated as safety issue: No ]
    Total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and hs-CRP were measured at 4 weeks after the start of the treatment period (after completion of administration of atorvastatin 10 mg alone) and at Week 16 or at discontinuation.

  • Percent Change in Total Lipids and Hs-CRP [ Time Frame: End of washout to Week 16 or discontinuation ] [ Designated as safety issue: No ]
    Total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and hs-CRP were measured at the start of the treatment period (at start of administration of atorvastatin 10 mg alone) and at the end of study drug (Week 16 or discontinuation).

Criteria

Inclusion Criteria:

  • atorvastatin 10 mg monotherapy for 4 weeks or longer before the start of the 4-week washout and low density lipoprotein-cholesterol (LDL-C) levels that had not reached the following lipid management target values during treatment: Category I (low-risk group) with no other risk factors - LDL-C <160 mg/dL; Category II (mid-risk group) with 1-2 risk factors other than LDL-C levels - LDL-C <140 mg/dL; Category III (high-risk group) with 3 or more other risk factors - LDL-C <120 mg/dL; and for participants with history of coronary artery disease - LDL-C <100 mg/dL.
