Blood:用Ravulizumab替代依库丽单抗治疗PNH疗效不变

2018-12-06 MedSci MedSci原创

Ravulizumab,是一种新的补体C5抑制剂,用于未进行过补体抑制剂治疗的阵发性夜间睡眠性血红蛋白尿(PNH)患者,每8周给药一次,效果不次于每2周用一次依库丽单抗。现Austin G. Kulasekararaj等人对ravulizumab相比依库丽单抗应用于临床稳定的PNH患者的非劣效性进行评估。研究人员开展一3期的开放性的多中心研究,195位应用依库丽单抗(900mg/2周)超过6个月的

Ravulizumab,是一种新的补体C5抑制剂,用于未进行过补体抑制剂治疗的阵发性夜间睡眠性血红蛋白尿(PNH)患者,每8周给药一次,效果不次于每2周用一次依库丽单抗。现Austin G. Kulasekararaj等人对ravulizumab相比依库丽单抗应用于临床稳定的PNH患者的非劣效性进行评估。

研究人员开展一3期的开放性的多中心研究,195位应用依库丽单抗(900mg/2周)超过6个月的PNH患者被随机(1:1)分至ravulizumab组(97人)或依库丽单抗组(98人,继续用依库丽单抗治疗)。主要结点是从起始到第183天时乳酸脱氢酶(LDH)的变化比例。次要结点包括突破性溶血的患者比例、慢性病治疗功能评估(FACIT)-疲劳评分的变化、输血减少和血红蛋白稳定。

191位患者完成183天的治疗,ravulizumab治疗的效果不比依库丽单抗差(所有p<0.0006),包括LDH的变化比例(差异9.21%[95% CI -0.42~18.84],p=0.058)、突破性溶血(5.1[95% CI -8.89~18.99])、FACIT-疲劳评分(1.47[95% CI -0.21~3.15])、输血减少(5.5[95% CI -4.27~15.68])和血红蛋白稳定(1.4[95% CI -10.41~13.31])。最常见的副反应是头痛(ravulizumab 25.8% vs 依库丽单抗 17.3%)。无脑膜炎球菌感染或因不良事件而停药。

总而言之,PNH患者,从每2周用一次依库丽单抗转为每8周用一次ravulizumab,效果不减,安全性佳。
