NEJM:Tapinarof乳膏治疗斑块状银屑病的效果

2021-12-09 MedSci原创 MedSci原创

在12周的治疗时间里,每天一次的1%Tapinarof乳膏在降低斑块状银屑病的严重程度方面优于对照软膏,但与局部不良事件和头痛有关。

Tapinarof乳膏是一种局部使用的芳烃受体调节剂,正在研究用于治疗银屑病。Tapinarof乳膏可调节白细胞介素17和皮肤屏障蛋白丝聚蛋白和loricrin的表达。

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员在轻度至重度斑块状银屑病患者中进行了两项相同的3期随机试验。基线医师总体评估(PGA)评分为2(轻度)至4(重度)(范围为0至4,分数越高表示银屑病越严重)且病变面积占总体表面积3至20%的患者以2:1的比例随机分配使用1%的tapinarof乳膏或对照乳膏,每天一次,持续治疗12周。

该研究的主要终点为PGA反应,即PGA评分为0(清除)或1(几乎清除)并且在第12周时比基线降低至少2分以上。该研究的次要疗效终点是银屑病面积和严重程度指数(PASI)得分至少减少75%,PGA得分为0或1,受影响的体表面积百分比相对于基线的平均变化以及PASI得分至少降低90%。患者报告的结局是从基线到第12周,在峰值瘙痒数字评定量表(PP-NRS)评分(范围为0[无痒]到10[最糟糕的瘙痒])、PP-NRS总分、皮肤病生活质量指数总分和银屑病症状日记评分。

在试验1和2中,该研究总共分别筛选了692和674名患者,其中纳入了510名和515名患者。在试验1中,Tapinarof软膏组中35.4%的患者和对照组中6.0%的患者发生了PGA反应,而在试验2中,分别为40.2%和6.3%(两种比较的P<0.001)。次要终点和患者报告的结局与主要终点的结局相同。Tapinarof乳膏的不良反应包括毛囊炎、鼻咽炎、接触性皮炎、头痛、上呼吸道感染和瘙痒。

由此可见,在12周的治疗时间里,每天一次的1%Tapinarof乳膏在降低斑块状银屑病的严重程度方面优于对照软膏,但与局部不良事件和头痛有关。与现有的银屑病治疗方法相比,需要更大型和更长时间的试验来评估Tapinarof乳膏的疗效和安全性。
