  Purpose

This study will assess whether co-administration of ezetimibe 10 mg with simvastatin 20 mg will be more effective than treatment with simvastatin 20 mg alone in reducing LDL-C concentrations when administered for 6 weeks.

Primary Outcome Measures:
  • Percent change in LDL-C from baseline to endpoint. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percent of subjects who achieve LDL-C ESC goal (ie, <3 mmol/L [115 mg/dL]) at endpoint. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline to endpoint in total cholesterol, HDL-C and triglycerides. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Safety: adverse events, laboratory test results, vital signs. [ Time Frame: Throughout study ] [ Designated as safety issue: Yes ]
