IBD:维多珠单抗可以长期维持中度至重度溃疡性结肠炎患者的临床缓解

2019-05-07 不详 MedSci原创

持续临床缓解是中重度UC的重要治疗目标。而维多珠单抗在维持UC缓解上有着比较优秀的效果,因此,本项研究旨在评估维多珠单抗在维持UC缓解上的效能。

背景
持续临床缓解是中重度UC的重要治疗目标。而维多珠单抗在维持UC缓解上有着比较优秀的效果,因此,本项研究旨在评估维多珠单抗在维持UC缓解上的效能。

方法
研究人员使用2个定义评估持续临床缓解(主要终点):(1)部分梅奥评分(pMS)≤2和(2)直肠出血分数(RBS)为0,所有患者使用维多珠单抗均持续14周,26周, 38和52周。

结果
接受维多珠单抗(n = 620)的患者与安慰剂组相比,第14周临床缓解的患者比例显着更高(n = 149)(pMS:32.7%vs 20.1%; 95 %置信区间[CI],5.2-20.0]; RBS:47.3% vs 28.9%[Δ18.4%; 95%CI,10.1-26.7])。在第14周临床缓解的患者中,维多珠单抗治疗患者的持续临床缓解率显着更高(pMS:66.5%vs 26.7%;Δ39.8%; 95%CI,22.7-56.9; RBS:56.7% vs 20.9%;Δ35.7%; 95%CI,22.3-49.1)。

结论
与安慰剂相比,接受维多珠单抗完全诱导疗程的患者在治疗52周后仍有35%-40%的患者持续临床缓解。第14周的临床缓解可能是维多珠单抗持续临床缓解的预测因子。
