AIM: In patients with hyperlipidemia, intolerance to statins presents a challenge in reducing the risk of events associated with cardiovascular disease. This phase 3, randomized, double-blind trial in Japanese patients with statin intolerance aimed to evaluate the efficacy and safety of evolocumab vs. ezetimibe in lowering low-density lipoprotein-cholesterol (LDL-C).
METHODS: This study was conducted in a 12-week, double-blind period followed by an open-label extension designed to characterize 1 year of evolocumab treatment. Statin intolerance was defined as failure of two or more statins due to myalgia, myositis, or rhabdomyolysis. Eligible patients were randomized at 2:2:1:1 into four groups: 420 mg evolocumab every 4 weeks (Q4W)＋oral placebo daily, 140 mg evolocumab every 2 weeks (Q2W)＋oral placebo daily, subcutaneous (SC) placebo Q4W＋10 mg ezetimibe daily, and SC placebo Q2W＋ 10 mg ezetimibe daily.
RESULTS: Sixty-one patients were randomized to evolocumab (n=40) or ezetimibe (n=21). For the co-primary endpoints of percent change from the baseline in mean LDL-C to the mean of weeks 10 and 12 and to week 12, the evolocumab-ezetimibe treatment differences were -39.4% (95% CI, -47.2% to -31.5%) and -40.1% (95% CI, -48.7% to -31.6%), respectively (adjusted p＜0.0001). The most common adverse events were diarrhea (9.5%) and nasopharyngitis (12.5%) in the ezetimibe and evolocumab groups, respectively, during the double-blind period and nasopharyngitis (29%) during the open-label extension.
CONCLUSION: Evolocumab was superior to ezetimibe in reducing LDL-C during the 12-week double-blind period in this population of Japanese patients with statin intolerance, with efficacy and safety results maintained for 1 year.
