Primary Outcome Measures:
  • Change From Baseline to End of Study (Week 104) in Percent Atheroma Volume (PAV) [ Time Frame: End of study (Week 104) ]

    Change in PAV computed as PAV(Week 104)-PAV(baseline) where PAV is calculated as:

    [sum(EEMcsa-LUMENcsa)/sum EEMcsa]*100 where EEMcsa is the cross-sectional area of the external elastic membrane and LUMENcsa is the cross-sectional area of the lumen, as measured by intravascular ultrasound IVUS of a coronary artery in patients with CAD.



Secondary Outcome Measures:
  • Numbers of Patients Showing Regression in PAV [ Time Frame: End of study (Week 104) ]
    Regression defined as a change from baseline in PAV < 0

  • Change From Baseline to End of Study (Week 104) in Total Atheroma Volume (TAV) [ Time Frame: End of study (Week 104) ]
    Change in TAV, as measured by IVUS, computed as TAV(Week 104)-TAV(baseline) where TAV is the sum(EEMcsa-LUMENcsa)/n. n is the number of cross-sections measured. TAV for each patient is calculated as the average area of atheroma per cross-section multiplied by the median number of cross-sections measured for all patients in the analysis population.

  • Numbers of Patients Showing Regression in TAV [ Time Frame: End of study (Week 104) ]
    Regression defined as a change from baseline in TAV < 0

  • Total Cholesterol Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • LDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • HDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Triglycerides Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Non-HDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • LDL-C/HDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Total Cholesterol/HDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Non-HDL-C/HDL-C Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Apolipoprotein B Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Apolipoprotein A-1 Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • Apoliprotein B/Apolipoprotein A-1 Blood Level [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

  • VLDL-C During the 104 Week Treatment Period [ Time Frame: 104 weeks ]
    Time-weighted average is calculated as the lipid value times the number of days since last lipid assessment, summed for all and divided by the number of days from Part B randomization to date of the last lipid evaluation.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Clinical indication for coronary angiography
  • Angiographic evidence of Coronary Artery Disease (CAD), as defined by at least 1 lesion in a native coronary artery that has >20% reduction in lumen diameter by visual estimation
  • Left main coronary artery must have <=50% reduction in lumen diameter by visual estimation
  • LDL-C >100 mg/dL (2.6 mmol/L) for patients with no statin therapy in the past 4 weeks; LDL-C >80mg/dL (2.08mmol/L) for patients on therapy in the past 4 weeks

Exclusion Criteria:

  • Use of certain lipid-lowering medication for more than 3 months within the previous 12 months. Longer periods of treatment are not permitted because of the potential effects of such therapy on coronary atherosclerosis.
  • Patients who have symptoms consistent with moderate or greater severity of Congestive Heart Failure (CHF).
  • Clinically significant heart disease which, in the opinion of the Principal Investigator (or designee), is likely to require coronary bypass surgery, cardiac transplantation, surgical repair and/or replacement during the course of the study
