Information provided by (Responsible Party):
Merck Sharp & Dohme Corp.
To evaluate the percentage of patients with either established cardiovascular disease (CVD), at "high risk" of developing CVD or with diabetes who are on simvastatin 40mg, with fasting LDL-C > 2mmol/l, who are able to attain the recommended LDL-C target of < 2mmol/l following 6 weeks treatment with either ezetimibe/simvastatin 10/40mg, atorvastatin 40mg or rosuvastatin 10mg.

Condition Intervention Phase
Hypercholesterolemia Drug: ezetimibe (+) simvastatin Drug: Comparator: atorvastatin Drug: Comparator: rosuvastatin Phase 3

Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A MC, DB, Rand, Study to Evaluate Efficacy, Safety and Tolerability of Eze/Simva 10/40 mg, Atorva 40 mg, Rosuva 10 mg in Achieving LDL-C <2 mmol/l in Pts With CVD...on Simva 40 mg With LDL-C ³2 mmol/l

Primary Outcome Measures:
  • Percentage of Patients Achieving a Target of Fasting LDL-C of <2mmol/l at Study End [ Time Frame: 6 Weeks ]
    Fasting LDL-C was the primary efficacy variable. The primary efficacy analysis was based on the proportion of patients achieving a target of <2mmol/l in fasting LDL-C at study end.
