Patients with prior vascular disease remain at high risk for cardiovascular events despite intensive statin-based treatment. Inhibition of cholesteryl ester transfer protein by anacetrapib reduces low-density lipoprotein (LDL) cholesterol by around 25% to 40% and more than doubles high-density lipoprotein (HDL) cholesterol. However, it is not known if these apparently favorable lipid changes translate into reductions in cardiovascular events.
The REVEAL study is a randomized, double-blind, placebo-controlled clinical trial that is assessing the efficacy and safety of adding anacetrapib to effective LDL-lowering treatment with atorvastatin for an average of at least 4years among patients with preexisting atherosclerotic vascular disease. The primary assessment is an intention-to-treat comparison among all randomized participants of the effects of allocation to anacetrapib on major coronary events (defined as the occurrence of coronary death, myocardial infarction, or coronary revascularization).
Between August 2011 and October 2013, 30,449 individuals in Europe, North America, and China were randomized to receive anacetrapib 100mg daily or matching placebo. Mean (SD) age was 67 (8) years, 84% were male, 88% had a history of coronary heart disease, 22% had cerebrovascular disease, and 37% had diabetes mellitus. At the randomization visit (after at least 8weeks on a protocol-defined atorvastatin regimen), mean plasma LDL cholesterol was 61 (15) mg/dL and HDL cholesterol was 40 (10) mg/dL.
The REVEAL trial will provide a robust evaluation of the clinical efficacy and safety of adding anacetrapib to an effective statin regimen. Results are anticipated in 2017.
尽管接受了强化的他汀类药物治疗,但既往有血管疾病的患者发生心血管事件的风险仍然很高。阿那曲泊帕抑制胆固醇酯转运蛋白可使低密度脂蛋白(LDL)胆固醇降低约25%至40%,并使高密度脂蛋白(HDL)胆固醇增加一倍多。然而,尚不清楚这些明显有利的血脂变化是否能转化为心血管事件的减少。
REVEAL研究是一项随机、双盲、安慰剂对照的临床试验,旨在评估在已患有动脉粥样硬化性血管疾病的患者中,在使用阿托伐他汀进行有效的LDL降低治疗基础上,加用阿那曲泊帕平均至少4年的疗效和安全性。主要评估是对所有随机参与者进行意向性治疗比较,比较分配到阿那曲泊帕组对主要冠状动脉事件(定义为冠状动脉死亡、心肌梗死或冠状动脉血运重建的发生)的影响。
2011年8月至2013年10月期间,欧洲、北美和中国的30449名个体被随机分配接受每日100mg阿那曲泊帕或匹配的安慰剂。平均(标准差)年龄为67(8)岁,84%为男性,88%有冠心病史,22%有脑血管疾病,37%有糖尿病。在随机分组访视时(在按照方案定义的阿托伐他汀治疗方案至少治疗8周后),平均血浆LDL胆固醇为61(15)mg/dL,HDL胆固醇为40(10)mg/dL。
REVEAL试验将对在有效的他汀类药物治疗方案中加用阿那曲泊帕的临床疗效和安全性进行有力评估。预计2017年得出结果。
