Efficacy and safety of rosuvastatin 5 mg in combination with fenofibric acid 135 mg in patients with mixed dyslipidemia - a phase 3 study.

BACKGROUND: Patients with mixed dyslipidemia characterized by elevated low-density lipoprotein cholesterol (LDL-C), elevated triglycerides (TG), and reduced high-density lipoprotein cholesterol (HDL-C) often require combination therapy to improve multiple lipid and nonlipid parameters. This phase 3, multicenter, randomized, double-blind study evaluated the efficacy and safety of rosuvastatin 5 mg coadministered with fenofibric acid 135 mg in patients with mixed dyslipidemia.

METHODS: A total of 760 patients with TG ≥ 150 mg/dL, HDL-C <40 mg/dL (<50 mg/dL for women), and LDL-C ≥ 130 mg/dL were randomized for a 12-week treatment period to rosuvastatin 5 mg, fenofibric acid 135 mg, or rosuvastatin 5 mg + fenofibric acid 135 mg. The primary efficacy comparisons were mean percentage changes in HDL-C and TG (rosuvastatin + fenofibric acid vs. rosuvastatin monotherapy), and LDL-C (rosuvastatin + fenofibric acid vs. fenofibric acid monotherapy).

RESULTS: Treatment with rosuvastatin + fenofibric acid resulted in statistically significant greater improvements in HDL-C (23.0% vs. 12.4%; P < 0.001) and TG (-40.3% vs. -17.5%; P < 0.001), compared with rosuvastatin monotherapy; and LDL-C (-28.7% vs. -4.1%; P < 0.001), compared with fenofibric acid monotherapy. All secondary efficacy variables improved with combination therapy. Combination therapy was generally well tolerated with a safety profile consistent with individual monotherapies. No unexpected muscle, hepatic, or renal safety signals were identified with combination therapy versus individual monotherapies.

CONCLUSION: In conclusion, rosuvastatin 5 mg + fenofibric acid 135 mg resulted in comprehensive improvements in the lipid profile of patients with mixed dyslipidemia without unanticipated adverse events.
