OBJECTIVE: To evaluate the achievement of individual and combined lipid and lipoprotein/biomarker targets as specified by treatment guidelines with the combination of fenofibric acid and statin therapy in patients with mixed dyslipidemia.
METHODS: Data for the post hoc analyses were derived from three 12-week controlled studies and a 52-week extension study. Patients were treated with fenofibric acid 135 mg; low-, moderate-, or high-dose statin (rosuvastatin 10, 20, or 40 mg; atorvastatin 20, 40, or 80 mg; or simvastatin 20, 40, or 80 mg); or fenofibric acid + low- or moderate-dose statin in the controlled studies; and with fenofibric acid + moderate-dose statin in the extension study. Achievement of risk-stratified low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B (ApoB) targets; and optimal levels of ApoB <90 mg/dL, HDL-C >40/50 mg/dL in men/women, triglycerides (TG) < 150 mg/dL, and high-sensitivity C-reactive protein <2 mg/L were assessed.
RESULTS: In the controlled studies, significantly lower percentage of high-risk patients treated with fenofibric acid + moderate-dose statin, and significantly higher percentage of high-risk patients treated with fenofibric acid + low-dose statin, compared with corresponding-dose statin monotherapies, achieved their LDL-C (51.3% vs. 72.9%, p < 0.001) and non-HDL-C targets (53% vs. 38%, p = 0.02), respectively. Among all patients, optimal levels of ApoB, HDL-C, TG, and the combined target of LDL-C + non-HDL-C + ApoB + HDL-C + TG were achieved by higher percentage of patients treated with fenofibric acid + low- and moderate-dose statin versus corresponding dose-statin monotherapies (p ≤ 0.04 for all comparisons). In the extension study, significantly (p < 0.001 for all comparisons) higher percentage of patients had achieved individual and combined targets at final visit, compared with baseline.
CONCLUSIONS: In patients with mixed dyslipidemia, short-term treatment with the combination of fenofibric acid and low- or moderate-dose statin resulted in comparable or more patients achieving individual targets of non-HDL-C, ApoB, HDL-C, and TG, and combined targets for these parameters and LDL-C, compared with corresponding-dose statin monotherapy. In the long-term study, the proportion meeting these targets was significant, compared with baseline. Limitations include the post hoc nature of the analysis, and the fact that all patients had mixed dyslipidemia and majority were white, which limits generalization to other populations.
