Lancet:抗人黏膜地址素细胞黏附分子1单抗治疗中重度溃疡性结肠炎

2017-05-18 zhangfan MedSci原创

PF-00547659 对于中重度溃疡性结肠炎具备较好的疗效和安全性。最佳临床疗效剂量为22.5mg和75mg

PF-00547659与人黏膜地址素细胞黏附分子1 (MAdCAM-1)结合,可选择性地减少淋巴细胞进入肠道。近日研究人员对PF-00547659在中重度溃疡性结肠炎的疗效和安全性进行考察。

这项II期临床研究在21个国家的105个医疗中心进行,18-65岁的、有3个月以上的、活动性溃疡性结肠炎超出肛门边缘超过15厘米的、对常规治疗无效或不耐受的患者,随机接受7.5 mg,22.5 mg,75mg或 225 mg PF-00547659或安慰剂,每4周一次。主要终点是12周的缓解患者比例。

共357人参与研究,安慰剂组(n=73),7.5 mg (n=71), 22.5 mg (n=72), 75 mg (n=71), 225 mg (n=70)。PF-00547659较安慰剂12周缓解率提高(2.7%-16.7%)。将结果根据TNF-α抗性调整后,相比于安慰剂的差异性如下:7.5 mg组: 8.0% (90% CI 1.9 -14, p=0.0425), 22.5mg组:12.8% (5.6 -19.9, p=0.0099), 75mg组:11.8% (4.8 -18.8, p=0.0119), 225 mg 组:2.6%(-1.2 - 6.4, p=0.1803);安慰剂组不良事件率为5.5%,7.5mg组为14.1%,22.5mg组为1.4%,75mg组为4.1%,225mg组为4.3%。

研究表明,PF-00547659 对于中重度溃疡性结肠炎具备较好的疗效和安全性。最佳临床疗效剂量为22.5mg和75mg。
