使用risankizumab选择性的阻断IL23信号可以有效的缓解重症银屑病斑块患者

IL-23信号通路是银屑病发病的关键因素。研究人员近日在重症银屑病斑块患者中比较了risankizumab与ustekinumab效果。其中Risankizumab是IgG1人源化单克隆抗体通过与IL23的p19亚基结合阻断IL23信号通路而ustekinumab为IL12和IL23双重抑制剂。

研究招募了166名患者随机接受risankizumab(0周时单剂量注射18mg 或分别在第0,4,16周注射90mg或180mg)或ustekinumab(依据体重在0,4,16周服用45或90mg)。研究的主要终点是患者12周时银屑病面积和严重指数(PASI)较基线下降90%以上的比例。

研究结果如下:对于risankizumab组患者到达终点率为77%而ustekinumab为40%,其中PASI指数减少100%的risankizumab患者比例为45%而ustekinumab组为18%。治疗的效果可在risankizumab停止用药后持续20周。18mg risankizumab、90mg risankizumab与ustekinumab相比,分别有5 人 (12%), 6 人(15%), and 3 人 (8%)发生严重不良事件,包括两个基底细胞癌和一个心血管不良事件,180mg risankizumab未发生严重不良事件。

研究表明,使用risankizumab选择性的阻断IL23信号可以有效的缓解重症银屑病斑块患者。进一步的长期安全性考察准备进行。
