MeasureTime frame
Main Objective: In patients with primary hypercholesterolemia or mixed hyperlipidemia, evaluate: The LDL-C lowering efficacy of MK-0524B 2g (pooled across simvastatin doses of 20 and 40 mg) compared to MK-0524A 2g. ;Secondary Objective: In patients with primary hypercholesterolemia or mixed hyperlipidemia, evaluate: The effects of MK-0524B 2g (pooled across simvastatin doses of 20 and 40 mg) compared to simvastatin (pooled across doses of 20 and 40 mg) on HDL-C, TG, LDL-C, LDL-C:HDL-C ratio, non-HDL-C, Apo B, and Apo A-I. The effects of MK-0524B 2g (pooled across simvastatin doses of 20 and 40 mg) compared to MK-0524A 2g on HDL-C, TG, LDL-C:HDL-C ratio, non-HDL-C, Apo B, and Apo A-I. Safety and tolerability of MK-0524B Other secondary objectives: In patients with primary hypercholesterolemia or mixed hyperlipidemia, evaluate: Assess the effects of MK-0524B on TC, Lp(a), TC:HDL ratio, RLP-C, CRP, Apo C-III, VLDL-C, and lipid subfractions. ;Primary end point(s): In patients with primary hypercholesterolemia or mixed hyperlipidemia MK-0524B 2g (pooled across simvastatin doses of 20 and 40 mg) will produce greater reductions in LDL-C than MK-0524A 2g.
