Background: We compared the lipid-altering effects of ezetimibe/simvastatin (EZE/SIMVA) co-administered with fenofibrate (FENO) in mixed hyperlipidemic patients with (MetS) versus those without MetS.
Methods: A total of 611 patients, 20 to 79 years old, with LDL-C 130-220 mg/dL (100-180 mg/dL for patients with type 2 diabetes [T2D]), triglycerides (TG) 150-500 mg/dL, and no history of CHD or other CHD risk equivalent disease (except for T2D), were randomized in a 1:3:3:3 ratio into one of the following four treatments for 12 weeks: placebo; EZE/SIMVA 10/20 mg; FENO 160 mg; or EZE/SIMVA+FENO. MetS status was determined in 607 patients using National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. Percentage change from baseline in low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, total cholesterol (TC), TG, apolipoproteins A-I and B, and C-reactive protein was assessed in these patients with or without MetS. The primary objective was to evaluate the lipid-altering efficacy of EZE/SIMVA+FENO versus FENO monotherapy in the MetS versus non-MetS subgroups.
Results: At baseline, patients with MetS had a higher body mass index (BMI) and TG and lower HDL-C. At Week 12, treatment with EZE/SIMVA, FENO, and EZE/SIMVA + FENO led to similar improvements in lipid parameters in patients with MetS compared to those without MetS. Treatment with EZE/SIMVA + FENO and FENO also led to an increase in LDL particle-size pattern after 12 weeks in both subgroups of patients.
Conclusions: This post-hoc analysis suggested that co-administration of EZE/SIMVA+FENO had consistent benefits on the lipid profile in mixed hyperlipidemic patients with or without MetS.
