Efficacy and safety of fenofibric acid in combination with a statin in patients with mixed dyslipidemia: Pooled analysis of three phase 3, 12-week randomized, controlled studies.

BACKGROUND

Patients with mixed dyslipidemia often require combination therapy to manage multiple lipid abnormalities.

OBJECTIVE

To evaluate fenofibric acid in combination with a statin across three studies of patients with mixed dyslipidemia.

METHODS

As prospectively planned, data were pooled from three randomized, double-blind, phase 3 studies of patients with low-density lipoprotein cholesterol (LDL-C) ≥130mg/dL, triglycerides (TG) ≥150mg/dL, and high-density lipoprotein cholesterol (HDL-C) <40mg/dL (men) or <50mg/dL (women). A total of 2715 patients were randomly assigned to 12-week treatment with fenofibric acid 135mg monotherapy; low-, moderate-, or high-dose statin (rosuvastatin, simvastatin, or atorvastatin, depending on study) monotherapy; or fenofibric acid + low- or moderate-dose statin. The primary efficacy comparisons were mean percent change in HDL-C and TG (combination therapy vs. statin) and LDL-C (combination therapy vs. fenofibric acid).

RESULTS

Fenofibric acid + low-dose statin increased HDL-C (18.1% vs. 7.4%) and reduced TG (-43.9% vs. -16.8%) versus low-dose statin monotherapy and reduced LDL-C (-33.1% vs. -5.1%) versus fenofibric acid monotherapy (P <.001 for all). Fenofibric acid + moderate-dose statin increased HDL-C (17.5% vs. 8.7%) and reduced TG (-42.0% vs. -23.7%) versus moderate-dose statin monotherapy and reduced LDL-C (-34.6% vs. -5.1%) versus fenofibric acid monotherapy (P <.001 for all). Combination therapy was generally well tolerated, and safety profiles were similar to monotherapies. No rhabdomyolysis was reported.

CONCLUSION

In patients with mixed dyslipidemia, combination therapy simultaneously improved multiple lipid abnormalities more effectively than fenofibric acid or statin monotherapies.
