Sifalimumab是一种抗干扰素-α单克隆抗体,据一项新的研究表明,它或可有效治疗部分系统性红斑狼疮患者。

Sifalimumab是一种抗干扰素-α单克隆抗体,据一项新的研究表明,它或可有效治疗部分系统性红斑狼疮患者。

研究共纳入了431名系统性红斑狼疮(SLE)患者,涉及20个国家的107个地方。排除活动性、重症狼疮性肾炎以及伴有神经精神症状的SLE患者。

将患者随机分组,分别接受200毫克sifalimumab,600毫克sifalimumab,1200毫克sifalimumab,或安慰剂治疗,给药时间为第1天,第15天和第29天,此后每隔28天给药一次,共给药52周。

基线时期各组研究对象的特征相似,除了安慰剂组患者的病程短,以及600毫克治疗组一小部分患者同时接受霉酚酸酯治疗。

在第52周时,所有治疗组符合SLE疾病活动指数2000 (SLEDAI-2K)至少4点改善的主要疗效终点的患者数目,以及无显著恶化的英国狼疮评定组指数(BILAG)得分或医生的全球评估(PGA)明显高于安慰剂组。第24周时治疗效果达到高峰,然后趋于稳定。治疗组中更多的患者其皮肤红斑狼疮面积和严重程度指数评分都有所改善,且治疗组每天糖皮质激素减少至低于7.5毫克的患者比例也高于对照组。

治疗组更多的患者PGA得到了改善,且SLEDAI-2K中减少了≥4点。在600毫克和1200毫克治疗组中,出现耀斑需要糖皮质激素的治疗的患者比例较低。基线时期关节严重受影响的患者中,相比于对照组,治疗组受影响的关节减少的患者人数50%或更多的剂量相关增加。

研究人员并未发现补充或抗-dsDNA的水平发生明显变化。

接受安慰剂治疗的一名患者感染了带状疱疹病毒,而治疗组19名患者发生了此感染, 1200毫克sifalimumab治疗组患者的感染率最高。1200毫克治疗组中一名患者感染了肺结核。此外,还发生了几次其他的感染,但都已经治疗解决。
