Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Ezetimibe 10 mg; Participants treated with 10 mg/day ezetimibe added to an ongoing treatment of 10 mg/day atorvastatin.	Drug: Ezetimibe; 10 mg ezetimibe, orally, daily for 6 weeks, added to ongoing treatment with 10 mg atorvastatin; Drug: Atorvastatin 10 mg; 10 mg/day atorvastatin, orally, (ongoing treatment in participants)
Placebo Comparator: Placebo 10 mg; Participants treated with 10 mg/day matching placebo to ezetimibe added to an ongoing treatment of 10 mg/day atorvastatin.	Drug: Atorvastatin 10 mg; 10 mg/day atorvastatin, orally, (ongoing treatment in participants); Drug: Placebo; 10 mg/day matching placebo to ezetimibe, orally, daily for 6 weeks, added to ongoing 10 mg atorvastatin

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Low Density Lipoprotein-cholesterol (LDL-C) at Baseline and After 6 Weeks of Treatment With Ezetimibe 10 mg Added to Atorvastatin 10 mg Versus Placebo Added to Atorvastatin 10 mg	12-hour fasting blood samples were collected in participants to measure high density lipoprotein-cholesterol (HDL-C), triglycerides and total cholesterol. LDL-C was measured using Friedewald calculation (LDL-C = Total C - [HDL-C + TG/5]) before and after treatment.	Baseline and 6 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants Who Achieve the Target LDL-C Concentration of < 3.3 mmol/L (130 mg/dL)	12-hour fasting blood samples were collected in participants to measure high density lipoprotein-cholesterol (HDL-C), triglycerides and total cholesterol. LDL-C was measured using Friedewald calculation (LDL-C = Total C - [HDL-C + TG/5] after treatment for 6 weeks.	6 weeks post treatment
High Density Lipoprotein-cholesterol (HDL-C), Total Cholesterol and Triglycerides at Baseline and After 6 Weeks of Treatment With Ezetimibe 10 mg Added to Atorvastatin 10 mg Versus Placebo Added to Atorvastatin 10 mg	12-hour fasting blood samples were collected in participants and the high density lipoprotein-cholesterol (HDL-C), triglycerides and total cholesterol was measured with the basic lipid panel test.	6 weeks post treatment
