Efficacy and safety of adding fenofibrate 160 mg in high-risk patients with mixed hyperlipidemia not controlled by pravastatin 40 mg monotherapy

Abstract

Patients with mixed hyperlipidemia and at high risk of coronary heart disease may not achieve recommended low-density lipoprotein (LDL) and non-high-density lipoprotein (non-HDL) cholesterol goals on statin monotherapy. This study was designed to evaluate the efficacy and safety of a fenofibrate 160 mg/pravastatin 40 mg fixed-dose combination therapy in high-risk patients not at their LDL cholesterol goal on pravastatin 40 mg. In this 12-week, multicenter, randomized, double-blind, double-dummy, parallel-group study, after a run-in on pravastatin 40 mg, 248 patients were randomly assigned to fenofibrate/pravastatin combination therapy or to pravastatin monotherapy. Combination therapy produced significantly greater complementary decreases in non-HDL cholesterol (primary end point) than pravastatin monotherapy (-14.1% vs -6.1%, p = 0.002). Significantly greater improvements were also observed in LDL cholesterol (-11.7% vs -5.9%, p = 0.019), HDL cholesterol (+6.5% vs +2.3%, p = 0.009), triglycerides (-22.6% vs -2.0%, p = 0.006), and apolipoprotein B (-12.6% vs -3.8%, p <0.0001). Significantly more patients receiving the fenofibrate/pravastatin combination therapy than pravastatin alone achieved the LDL cholesterol (<100 mg/dl) and non-HDL cholesterol (<130 mg/dl) goals (p <0.01). Combination therapy was generally well tolerated with incidences of clinical and laboratory adverse experiences similar between the 2 groups. In conclusion, the fenofibrate 160 mg/pravastatin 40 mg fixed-dose combination therapy significantly improved the global atherogenic lipid profile in high-risk patients with mixed hyperlipidemia not controlled by pravastatin 40 mg monotherapy.
