Ann Rheum Dis:IL-6单克隆抗体治疗SLE?

2016-09-29 Moon 译 MedSci原创

最近的2期临床试验数据显示,剂量为10毫克的白细胞介素-6单克隆抗体,可以改善狼疮患者的复合响应率。 雪松-西奈医学中心的Daniel J. Wallace博士和同事对183例系统性红斑狼疮(SLE)患者进行了研究,患者被随机分为安慰剂治疗组n = 45)或IL-6单克隆抗体PF-04236921 (Pfizer)组,后者的剂量为10 mg (n = 45)、50 mg (n = 47)或2

最近的一项2期临床试验数据显示,剂量为10毫克的白细胞介素-6单克隆抗体,可以改善狼疮患者的复合响应率。

雪松-西奈医学中心的Daniel J. Wallace博士和同事对183例系统性红斑狼疮(SLE)患者进行了研究,患者被随机分为安慰剂治疗组n = 45)或IL-6单克隆抗体PF-04236921 (Pfizer)组,后者的剂量为10 mg (n = 45)、50 mg (n = 47)或200 mg (n = 46),每8周皮下注射一次。在第24周时,评估患者的SLE反应指数(SRI-4)和BICLA。

因为安全性问题,200 mg PF-04236921组的试验被终止,没有纳入疗效分析。

结果显示,除了10-mg PF-04236921组患者的SRI-4增加(与对照组相比),其他PF-04236921剂量组患者的SRI-4并没有比对照组更高。当10-mg与50-mg组结合,严重耀斑的发病率显着降低。基线疾病活动度增加的患者,经过10-mg PF-04236921治疗后,其SRI-4 (73.1% vs. 27.7%)和BICLA (55.7% vs. 19.7%)响应率增加。

200 mg PF-04236921组发生了3例死亡,10 mg PF-04236921组发生了1例死亡。最常见的不良事件是头痛、恶心和腹泻。

作者称:美国国立卫生研究院进行的一项1期研究表明,托珠单抗(Tocilizumab)对狼疮患者具有明显的抗炎作用;本项研究表明,阻断IL-6治疗SLE,还需要进一步的研究,也是值得的研究。
