Secukinumab是抗白介素17A单克隆抗体,已被证明在一期临床试验中可控制强直性脊柱炎的症状。研究人员对活动期强直性脊柱炎患者进行了两项secukinumab的3期试验(诺华单抗secukinumab强直性脊柱炎III期临床大获成功)。

在两个双盲试验中,研究人员随机分配患者接受secukinumab或安慰剂。在MEASURE1中,在0,2和4周时总共371名患者接受静脉secukinumab(每公斤体重10mg),或接受匹配的安慰剂,然后皮下静脉secukinumab(150mg或75mg),或匹配的安慰剂,开始于第8周的时候每4周一次。在MEASURE2中,一共有219名患者在基线时1,2,和3周接受皮下secukinumab(150mg或75mg)或安慰剂;在第4周开始时每4周一次。在16周时,安慰剂组患者随机重新分配接受皮下secukinumab在150mg或75mg的剂量。主要终点是在16周时脊柱关节炎国际评价协会(ASAS)响应标准的评估中至少20%的改善的患者比例。

在MEASURE1中,在第16周时,secukinumab剂量为150毫克和75毫克和安慰剂组ASAS20应答率分别为61%,60%,和29%(P <0.001对于与安慰剂的比较);在MEASURE2中,secukinumab剂量为150毫克和75毫克和安慰剂组ASAS20应答率分别为61%,41%,和28%(对于150毫克的剂量P<0.001,对于75毫克剂量P=0.10)。该显著的改善持续到52周。在MEASURE1中的安慰剂对照期间,感染,包括念珠菌,secukinumab组比安慰剂组更常见。在整个治疗期间,调整发病率3或4级中性白细胞减少症,念珠菌感染和克罗恩病率在secukinumab治疗的患者中分别为0.7 ,0.9和0.7例每100患者-年。

Secukinumab在皮下剂量为150毫克,皮下或静脉内注射,可使16周强直性脊柱炎的症状显著减少。皮下剂量为75毫克Secukinumab导致仅更高静脉负荷剂量显著改善。
