PURPOSE: Evolocumab significantly reduces low-density lipoprotein-cholesterol (LDL-C); we investigated its effects on LDL-C lowering in patients with mixed hyperlipidemia. METHODS: We compared the efficacy and safety of evolocumab in hypercholesterolemic patients selected from the phase 2 and 3 trials who had fasting triglyceride levels ≥1.7 mmol/L (150 mg/dL elevated triglycerides) and <1.7 mmol/L (without elevated triglycerides). Fasting triglyceride level ≥ 4.5 mmol/L at screening was an exclusion criterion for these studies, but post-enrollment triglyceride levels may have exceeded 4.5 mmol/L (400 mg/dL). Efficacy was evaluated in four phase 3 randomized studies (n = 1148) and safety from the phase 2 and 3 studies (n = 2246) and their open-label extension studies (n = 1698). Efficacy analyses were based on 12-week studies, while safety analyses included data from all available studies. Treatment differences were calculated vs. placebo and ezetimibe after pooling dose frequencies. RESULTS: Mean treatment difference in percentage change from baseline in LDL-C for participants with elevated triglycerides and those without elevated triglycerides (mean of weeks 10 and 12) with evolocumab was approximately -67 % vs. placebo and -42 % vs. ezetimibe (all P < 0.001) compared to −65 % vs. placebo and −39 % vs. ezetimibe, [corrected] respectively. Treatment differences for evolocumab vs. placebo and ezetimibe followed a similar pattern for non-high-density lipoprotein (HDL-C) and apolipoprotein B. Evolocumab was well tolerated, with balanced rates of adverse events leading to discontinuation of evolocumab vs. comparator (placebo and/or ezetimibe). CONCLUSION: The significant reductions of atherogenic lipids including LDL-C, non-HDL-C, and apolipoprotein B seen with evolocumab are similar in patients with and without mixed hyperlipidemia.
