NEJM:Daprodustat治疗非透析慢性肾病患者贫血的效果

达普司他与常规促红细胞生成素α纠正肾性贫血哪家强?

达普司他(Daprodustat)是一种口服的缺氧诱导因子脯氨酰基羟化酶抑制剂(HIF-PHI),已获批用于治疗由慢性肾脏病(CKD)引起的肾性贫血。但迄今为止,在未接受透析的慢性肾病 (CKD) 患者中,达普司他与常规促红细胞生成素α 相比的有效性和安全性尚不清楚。

这是一项随机、开放标签、对血管结局进行盲审的3期临床试验,对比了达普司他和阿法达贝泊 (Darbepoetin alfa) 治疗未接受透析的CKD患者贫血的疗效。主要终点是血红蛋白水平从基线到第28周到第52周的平均变化和首次重大心血管不良事件(MACE:全因死亡、非致死性心肌梗死或非致死性卒中的复合结局)的发生。

两组血红蛋白水平的变化

总体上,共3872位患者被随机分成了两组,接受达普司他或阿法达贝泊治疗。两治疗组的平均(±SD)基线血红蛋白水平相近。达普司他组和阿法达贝泊组血红蛋白水平从基线到第28周到第52周的平均(±SE)变化分别为0.74±0.02 g/分升 vs 0.66±0.02 g/分升(差 0.08/分升,95% CI 0.03-0.13),该结果符合预先设定的非劣效界限(-0.75 g/分升)。

两组MACE事件的累积发生率

中位随访了1.9年,达普司他组1937位患者中有378位(19.5%)发生了首次MACE事件,而阿法达贝泊组1935位患者中有371位(19.2%;风险比 1.03,95% CI 0.89-1.19),该结果符合预定的非劣效界限(1.25)。两组患者发生不良事件的百分比相似。

简而言之,在没有进行透析治疗的合并贫血的慢性肾病患者中,就血红蛋白水平的变化和心血管结局而言,达普司他的效果不劣于阿法达贝泊
