Background: Co-administration of a fibrate and statin is an effective treatment option for patients with multiple lipid abnormalities, yet adequate long-term safety and efficacy data are lacking.
Objective: To evaluate the long-term safety and efficacy of fenofibric acid combined with statins in adults with mixed dyslipidemia.
Methods: Three large, 12-week, phase three, double-blind, randomized, controlled trials evaluated fenofibric acid 135 mg combined with a low- or moderate-dose statin compared to fenofibric acid or statin monotherapy, and a subsequent 52-week open-label extension study evaluated fenofibric acid 135 mg combined with moderate-dose statin (rosuvastatin 20 mg, simvastatin 40 mg, or atorvastatin 40 mg). This prespecified analysis integrated results from these studies to assess the long-term safety and efficacy of combination therapy.
Results: Across the controlled studies and the extension study, 2201 patients received at least one dose of fenofibric acid + statin for a median duration of 364 days. The most common adverse events were headache, upper respiratory tract infection, nasopharyngitis, and back pain, with the incidence of all adverse events being similar across all combination therapy treatment groups. Rhabdomyolysis or treatment-related death was not reported in any group. Combination therapy resulted in sustained improvements in multiple lipid parameters, including triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, total cholesterol, apolipoprotein B, and high-sensitivity C-reactive protein.
Conclusion: Long-term fenofibric acid + statin combination therapy was generally well tolerated and resulted in comprehensive and sustained improvements in multiple lipid parameters in adults with mixed dyslipidemia.
