银屑病是一种慢性炎症性疾病,最常见的银屑病类型是斑块状银屑病,表现为厚而有鳞的斑块。PF-06700841是一种口服的、选择性的、TYK2/Jak1双重抑制剂,I期临床试验结果显示PF-06700841可有效减轻银屑病患者的疾病活动性。近日,研究人员报道了IIa期多中心试验的结果,已发表于J Invest Dermatol。

研究共纳入了35个地点的212名患者,随机接受PF-06700841 30 mg每日一次(QD)、60 mg QD或安慰剂(4周诱导),随后接受10 mg QD、30 mg QD、100 mg每周一次或安慰剂(8周维持)。主要终点是第12周PASI评分较基线的变化。次要终点是第12周时,从基线PASI减少75%和90%的患者比例。

 

结果显示,平均(SD)基线PASI评分为20.8(7.68)。与安慰剂相比,五个治疗组的PASI在第12周显著下降。30毫克QD连续治疗组观察到最大程度的下降(最小二乘法平均变化-17.3[95%置信区间,-20.0至-14.6])。总的来说,136名患者治疗过程中出现不良事件,包括5名患者的6个严重不良事件和13个因不良事件而中断治疗。未发生带状疱疹病例或包括血栓栓塞事件在内的重大血管不良事件。

综上所述,该研究结果表明,PF-06700841对中度至重度斑块状银屑病患者普遍有效且耐受性良好。
