NEJM:Brodalumab治疗中度至重度银屑病,效果良好

2015-10-01 MedSci MedSci原创

早期的临床研究表明,抗白介素17受体A的单克隆抗体brodalumab对于治疗银屑病很有疗效。在两个3期研究中(AMAGINE-2和AMAGINE-3),中度至重度银屑病患者被随机分配接受brodalumab(每2周210毫克或140毫克),ustekinumab(患者体重≤100 kg时45毫克,患者>100kg时90毫克),或安慰剂。在第12周时,接受brodalumab的患者被随机再次分配接

早期的临床研究表明,抗白介素17受体A的单克隆抗体brodalumab对于治疗银屑病很有疗效(此前报道:牛皮癣新药IL-17受体单抗brodalumab三期研究获得成功)。

在两个3期研究中(AMAGINE-2和AMAGINE-3),中度至重度银屑病患者被随机分配接受brodalumab(每2周210毫克或140毫克),ustekinumab(患者体重≤100 kg时45毫克,患者>100kg时90毫克),或安慰剂。在第12周时,接受brodalumab的患者被随机再次分配接受brodalumab维持剂量为每2周210毫克或每2周,每4周或每8周140毫克;接受ustekinumab的患者继续接受每12周的ustekinumab,安慰剂组患者接受每2周210毫克的brodalumab。主要目的是评估在第12周时brodalumab相对于安慰剂的优越性,达到银屑病面积和严重度指数得分至少减少了75%(PASI 75),以及静态医师整体评估(sPGA)为0或1(清晰或几乎清晰的皮肤),以及在第12周时在PASI评分的降低100%(PASI 100)方面,brodalumab相对于ustekinumab的优越

在第12周时,brodalumab 210毫克和140毫克的剂量的PASI 75应答率分别高于安慰剂(分别为86%和67% vs 8%[AMAGINE-2],85%和69% vs 6%[AMAGINE-3],P<0.001);brodalumab组SPGA分数为0或1的概率也较高(P<0.001)。在第12周时,brodalumab 210毫克剂量的PASI 100反应率显著高于ustekinumab组患者(44% vs 22%[AMAGINE-2]和37% vs 19%的[AMAGINE-3],P<0.001)。在AMAGINE-2中,brodalumab 140毫克剂量组的PASI 100反应率为26%(与ustekinumab比较P=0.08),在AMAGINE-3中为27%(P=0.007)。服用brodalumab和ustekinumab的患者的中性粒细胞减少的发生率高于安慰剂组患者。服用brodalumab的患者发生轻度或中度念珠菌感染的频率比ustekinumab或安慰剂更频繁。到52周时,服用brodalumab患者的重大传染性发生率分别为每100病人年1.0(AMAGINE-2)和1.3(AMAGINE-3)。

Brodalumab治疗中度至重度银屑病的患者得到了显著临床改善。
