JAMA Dermatol:Nomacopan治疗大疱性类天疱疮老年患者的耐受性良好,疗效佳

大疱性类天疱疮是一种难以治疗的自身免疫性大疱性皮肤病,主要影响老年人,并与死亡率的增加有关。

大疱性类天疱疮是一种难以治疗的自身免疫性大疱性皮肤病,主要影响老年人,并与死亡率的增加有关。近日,发表于JAMA Dermatol的一项研究探究了白三烯B4和补体C5抑制剂Nomacopan在大疱性类天疱疮患者中的安全性和治疗潜力。

这项多中心、单组、2a期非随机对照试验在荷兰和德国的大学皮肤科进行。2018年9月至2020年4月期间纳入轻度至中度、新发或复发的大疱性类天疱疮的老年患者(年龄≥55岁)。患者在第1天接受Nomacopan,90毫克,皮下注射,每天皮下注射30毫克,直到第42天。主要终点是发生与Nomacopan有关或可能有关的3-5级(严重)不良事件的患者比例。次要终点包括丘疹性红斑狼疮疾病区域指数(BPDAI)活动评分的平均绝对值和百分比变化、BPDAI瘙痒评分,以及患者报告的结果指标皮肤病生活质量指数(DLQI)和自身免疫性丘疹性疾病治疗生活质量(TABQOL)。

结果,共有9名大疱性类天疱疮患者(中位[范围]年龄,75[55-85]岁)纳入试验,其中5名是女性(55.6%)。没有发现与Nomacopan有关的严重不良事件。平均(90%CI)BPDAI活动评分从第1天的32.0(8.7)分降至第42天的19.6(9.0)分。9名患者中有7名(77.8%)对Nomacopan有反应,在第1天和第42天之间,BPDAI活动得分至少减少了8分;在3名反应者中,减少了80%或更多。在第42天,平均(90%CI)BPDAI瘙痒评分从第1天的17.6(4.0)分下降了6.8(4.6)分。平均(90%CI)DLQI得分从基线的11.3(4.2)分下降到第42天的6.4(3.8)分,平均(90%CI)TABQOL得分从基线的14.6(5.4)分下降到第42天的10.3(5.0)分。

综上所述,这项非随机对照试验的结果表明,Nomacopan在老年大疱性类天疱疮患者中的耐受性良好,对抑制这种疾病的急性发作可能有治疗作用。有必要进行更大规模的安慰剂对照的随机临床试验,以证实这种安全性,并将Nomacopan确立为治疗大疱性类天疱疮的新治疗选择。
