    Abstract

    Purpose: The aim of this study was to evaluate the safety and efficacy of combination treatment of rosuvastatin with ezetimibe in patients with primary hypercholesterolemia. Methods: This multicenter, randomized, double-blind study comprised a main study and an extension study. In the main study, the efficacy and safety of a combination of rosuvastatin (5, 10, and 20 mg) with ezetimibe (10 mg) were compared with those of rosuvastatin (5, 10, and 20 mg) alone. The subjects who achieved the National Cholesterol Education Program Adult Treatment Panel III LDL-C goal in the main study and agreed to a further study were enrolled for the extension study. In the extension study, ezetimibe 10 mg was also administered to subjects who had received rosuvastatin (5, 10, and 20 mg) alone in the main study, and the same treatment was continued for subjects who had received a combination of rosuvastatin with ezetimibe in the main study. Findings: At the end of the main study (week 8), LDL-C levels were significantly lower in subjects receiving combination therapy than in those receiving rosuvastatin monotherapy. Other lipid profiles also significantly improved in the combination therapy group. These improvements continued in the extension study. The combination therapy of rosuvastatin and ezetimibe was generally well tolerated. At the end of the main study, more subjects achieved the National Cholesterol Education Program Adult Treatment Panel III LDL-C goal in the combination therapy group than in the monotherapy group. The increased dosage of rosuvastatin was also well tolerated in the combination treatment. Implications: Combination therapy of ezetimibe 10 mg with varying doses of rosuvastatin that are commonly used in the clinical field improved the lipid profile and allowed more subjects to reach the LDL-C goal in primary hypercholesterolemia compared with rosuvastatin monotherapy. In addition, the efficacy of the combination therapy was maintained for the extended period. Additional beneficial changes were also achieved with combination therapy even in patients who responded well to rosuvastatin monotherapy. ClinicalTrials.gov identifier: NCT03288038.
