JAMA:维利西呱(Vericiguat)对恶性慢性心力衰竭疗效不显著

心血管病药物维利西呱(威利西呱, Vericiguat)是一款口服可溶性鸟苷酸环化酶(sGC)调节剂,用于治疗恶性慢性心力衰竭和左心室射血分数 (LVEF)降低的患者。研究者进行了一项2期试验,探究该药物的最佳剂量和耐受性。该随机研究纳入了2013年11月-2015年1月的456名患者,随访至2015年6月。恶性慢性心力衰竭患者且4周内LVEF≤45%,若出现利钠肽水平水平升高到需要住院治疗或门诊

心血管病药物维利西呱(威利西呱, Vericiguat)是一款口服可溶性鸟苷酸环化酶(sGC)调节剂,用于治疗恶性慢性心力衰竭和左心室射血分数 (LVEF)降低的患者。研究者进行了一项2期试验,探究该药物的最佳剂量和耐受性。

该随机研究纳入了2013年11月-2015年1月的456名患者,随访至2015年6月。恶性慢性心力衰竭患者且4周内LVEF≤45%,若出现利钠肽水平水平升高到需要住院治疗或门诊静滴利尿剂,则为情况恶化。

研究分为安慰剂组 (n = 92) 或口服Vericiguat(1.25 mg [n = 91], 2.5 mg [n = 91], 5 mg [n = 91], 10 mg [n = 91]),持续12周。初始结局指标为12周后NT-proBNP变化情况。

共有351(77.0%)名患者完成了12周的实验,获取了12周后NT-proBNP情况。研究数据显示 NT-proBNP水平的对数转换变化在合并的vericiguat组(对数转换:基线, 7.969; 12 周, 7.567;相差, −0.402; 几何平均数: 基线, 2890 pg/mL; 12周, 1932 pg/mL)和安慰剂组(对数转换:基线, 8.283; 12 周, 8.002;相差, −0.280; 几何平均数: 基线, 3955 pg/mL; 12周, 2988 pg/mL)差异不大 (均差, −0.122; 90% CI, −0.32 to 0.07;几何均数相比, 0.885, 90% CI, 0.73-1.08; P = .15)。继发性分析显示一个剂量依赖效应,vericiguat 的剂量越高,降低 NT-proBNP的效果越好(P < .02)。安慰剂组和vericiguat组不良事件发生分别为 77.2%和71.4%。

研究结果表明,对恶性慢性心力衰竭+LVEF降低的患者使用vericiguat,并不能显著改善12周后NT-proBNP水平,不过该药物耐受性可。以后还需要更多的关于该药物剂量反应关系的试验。
