A Study to Evaluate the Effectiveness of Ezetimibe/Atorvastatin 10 mg/40 mg Combination Tablet Compared to Marketed Ezetimibe 10 mg and Atorvastatin 40 mg Tablets in Participants With High Cholesterol (MK-0653C-190 AM1)

February 7, 2022 updated by: Organon and Co

A Randomized, Double-Blind, Active-Controlled, Multicenter, Crossover Study to Evaluate the Efficacy of Ezetimibe/Atorvastatin 10 mg/40 mg Fixed-Dose Combination Tablet Compared to Co-Administration of Marketed Ezetimibe 10 mg and Atorvastatin 40 mg in Patients With Primary Hypercholesterolemia

The purpose of this study is to determine whether ezetimibe/atorvastatin 10 mg/40 mg combination tablet is equivalent to the coadministration of ezetimibe 10 mg and atorvastatin 40 mg in lowering low-density-lipoprotein-cholesterol (LDL-C) after 6 weeks of treatment.
