在所有 3 项关键的 UNCOVER 研究中,均将甲银屑病严重程度指数(NAPSI)衡量的甲银屑病疗效作为次要终点。1 为了计算 NAPSI,每个指甲被分为四个象限,并评估存在(1)或不存在(0)甲床银屑病和甲母质银屑病表现(每个指甲的评分范围为 0-8 分)。 NAPSI 总得分为 10 个单独指甲评分的总和,范围介于 0 分(无甲银屑病)至 80 分(重度甲银屑病)。2
高达 82% 的银屑病患者存在甲受累。3-5
UNCOVER-1 研究: 基线甲银屑病患者从第 60 周至第 264 周的甲银屑病完全缓解(NAPSI=0),观察病例,UNCOVER-2 研究:基线甲银屑病患者至第 264 周的甲银屑病完全缓解(NAPSI=0),观察病例 和UNCOVER-3 研究:基线甲银屑病患者至第 264 周的甲银屑病完全缓解(NAPSI=0)显示了在接受批准的依奇珠单抗给药方案的基线甲银屑病患者中的长期指甲疗效应答。 在两项研究中,作者得出结论,通过依奇珠单抗的长期治疗,甲银屑病的良好疗效得以维持至 5 年。6-8
图 1:UNCOVER-1 研究的观察性数据显示,甲银屑病完全缓解的患者的比例在第 60 周为 61%,在第 264 周为 75%。
缩略词: NAPSI = 甲银屑病严重程度指数。
图 2: UNCOVER-2 研究的观察性数据显示,甲银屑病完全缓解的患者的比例在第 60 周为 66%,在第 264 周为 72%。
缩略词:IXE = 依奇珠单抗;Nx = 非缺失数据患者数量;NAPSI = 甲银屑病严重程度指数; Q2W = 每 2 周一次;Q4W = 每 4 周一次。

图 3:UNCOVER-3 研究的观察性数据显示,第 264 周甲银屑病完全缓解的患者的比例为 77%。
缩略词:IXE = 依奇珠单抗;MI = 多重填补;mNRI = 修正后的无应答者填补;NAPSI = 甲银屑病严重程度指数; Q2W = 每 2 周一次;Q4W = 每 4 周一次。
