Safety and Efficacy Study Using ABT-335 (Investigational Drug) in Combination With Atorvastatin, to Study the Effects on Thickening of the Blood Vessel Wall in Patients With Abnormal Lipid (Fat) Levels in the Blood

Rate of Change in Mean of Maximal Posterior-wall Carotid Intima-media Thickness (cIMT)

Rate of change (mm/year) from baseline in mean of maximal posterior-wall carotid intima-media thickness (cIMT) of the left and right common carotid artery. The statistical model used change from baseline as the dependent variable, with time of cIMT assessment (in years) as one of the factors in the model. The between-group difference in the rate of change was based on the parameter coefficient for the time-by-treatment interaction. The within-group rate of change was obtained from estimate statements within the repeated measures analysis. cIMT was measured using non-invasive ultrasound.

Time frame: Baseline, 6 months, 12 months, 18 months, and 24 months

Rate of Change in Composite of Mean of the Mean Posterior-wall Intima-media Thickness (IMT)

Rate of change (mm/year) from baseline in composite of mean of the mean posterior-wall intima-media thickness (IMT) of the left and right common carotid artery, internal carotid artery, and carotid bifurcation. The statistical model used change from baseline as the dependent variable, with time of IMT assessment (in years) as one of the factors in the model. The between-group difference in the rate of change was based on the parameter coefficient for the time-by-treatment interaction. The within-group rate of change was obtained from estimate statements within the repeated measures analysis. IMT was measured using non-invasive ultrasound.

Time frame: Baseline, 6 months, 12 months, 18 months, and 24 months

Rate of Change in Composite of Mean of Maximal Posterior-wall and Anterior-wall Intima-media Thickness (IMT)

Rate of change (mm/year) from baseline in composite of mean of maximal posterior-wall and anterior-wall intima-media thickness (IMT) of the left and right common carotid artery, internal carotid artery, and carotid bifurcation. The statistical model used change from baseline as the dependent variable, with time of IMT assessment (in years) as one of the factors in the model. The between-group difference in the rate of change was based on the parameter coefficient for the time-by-treatment interaction. The within-group rate of change was obtained from estimate statements within the repeated measures analysis. IMT was measured using non-invasive ultrasound.
