Ann Rheum Dis:atacicept 对预防SLE红斑有效

2015-10-25 candy 译 MedSci原创

目的:在系统性红斑狼疮(SLE)的治疗进展,许多患者仍然在疾病中挣扎,需要承受各种药物的副作用。目前出现的Atacicept是一种融合蛋白,它可以阻止B淋巴细胞刺激因子和增殖诱导配体,所以研究者假设对SLE患者的治疗有效果。方法:采取双盲安慰剂-对照试验,将中重度SLE病人随机分为用药组与安慰剂对照组。用药组随机予皮下注射75mg或150mg的atacicept,对照组给予安慰剂;以每周两次,共4

目的:在系统性红斑狼疮(SLE)的治疗进展,许多患者仍然在疾病中挣扎,需要承受各种药物的副作用。目前出现的Atacicept是一种融合蛋白,它可以阻止B淋巴细胞刺激因子和增殖诱导配体,所以研究者假设Atacicept对SLE患者的治疗有效果。

方法:采取双盲安慰剂-对照试验,将中重度SLE病人随机分为用药组与安慰剂对照组。用药组随机予皮下注射75mg或150mg的atacicept,对照组给予安慰剂;以每周两次,共4周的频率用药,48周后改为每周一次。最主要和次要的效果测量分别为经BILAG(英国埃尔斯狼疮评估)评估组A或B后,至少有一次红斑发作经历的病人比例和首次红斑发作时间。

结果:用药组中予以150mg  atacicept的病例中,因有2例死亡而使本组的实验过早中止。在意向治疗人群中(n=461),红斑率或首次发作时间与Atacicept 75mg或是安慰剂之间均无明显差异。从150 mg atacicept组的数据分析表明,Atacicept较安慰剂而言,对红斑发作率和首次发作时间有很好的效果(OR: 0.48, p=0.002;HR: 0.56, p=0.009)。两种atacicept剂量对总球蛋白水平和抗dsDNA抗体的减少都有相关性,另外与C3和C4水平的增加也存在相关性。大多数治疗出现的不良反应仅为轻微或中度。

结论:75mg atacicept和安慰剂对红斑发生率与首次发作无差异。组的分析表明150mg atacicept对系统性红斑狼疮(SLE)有效。
