The objective of this study was to evaluate the long-term efficacy of adding fenofibric acid to moderate-dose statin therapy in patients at goal for low-density lipoprotein cholesterol (LDL-C) but with persistent hypertriglyceridemia.

This is a post hoc analysis of a subset of patients (N = 92) with mixed dyslipidemia treated with moderate-dose statin (rosuvastatin 20 mg, simvastatin 40 mg, or atorvastatin 40 mg) for 12 weeks in three controlled trials who had achieved LDL-C <100 mg/dL but whose triglycerides remained >200 mg/dL, and had fenofibric acid 135 mg added to the moderate-dose statin in a 52-week open-label extension study. Lipid and apolipoprotein (Apo) values and the proportion of patients meeting individual and combined treatment targets with combination therapy were determined at scheduled visits during the 52-week study and compared with baseline (start of extension study).

Addition of fenofibric acid to moderate-dose statin for 52 weeks resulted in significant (P < 0.001) improvements in non-high-density lipoprotein cholesterol (non-HDL-C; -9.0%), ApoB (-9.8%), HDL-C (14.9%), and triglycerides (-37.6%) compared with baseline. At final visit, greater proportions of patients achieved optimal levels of individual parameters as well as combined targets of LDL-C + non-HDL-C (60.0% vs 52.2%), LDL-C + non-HDL-C + ApoB (53.3% vs 37.8%, P = 0.007), and LDL-C + non-HDL-C + ApoB + HDL-C + triglycerides (25.6% vs 0.0%) than at baseline.

The addition of fenofibric acid to moderate-dose statin in patients whose LDL-C was optimal but whose triglycerides remained >200 mg/dL led to additional improvements in non-HDL-C, ApoB, HDL-C, and triglycerides that resulted in greater proportions of patients attaining optimal levels of the individual parameters as well as simultaneously achieving optimal levels of these parameters and LDL-C.
