研究认为,difelikefalin可改善透析患者瘙痒症状,瘙痒相关的生活质量得到改善

Difelikefalin是kappa阿片受体的一种外周限制性和选择性激动剂,在调节慢性肾脏疾病瘙痒中起重要作用。

在III期临床研究中,中度至重度瘙痒透析患者,随机接受静脉滴注difelikefalin(剂量为每公斤体重0.5μg)或安慰剂,每周三次,持续12周。研究的主要结果是12周24小时最严重瘙痒强度数值(WI-NRS;评分范围从0到10,分数越高,瘙痒强度越大)减少3分的患者百分比。次要结果包括瘙痒相关生活质量、第12周WI-NRS评分改善至少4分的患者百分比以及安全性。

共有378名患者参与研究,其中difelikefalin组158例患者,与安慰剂组165例。12周时WI-NRS评分(主要结果)至少下降了3分患者比例分别为:安慰剂组51例vs difelikefalin组82例(30.9% vs 51.9%)。difelikefalin组WI-NRS评分至少下降3分患者的估算百分比为49.1%,而安慰剂组为27.9%。根据5-D瘙痒量表和Skindex-10量表,从基线检查到第12周,Difelikefalin显著改善了瘙痒相关的生活质量。第12周WI-NRS评分下降至少4分的患者的估算百分比,difelikefalin组明显高于安慰剂组(37.1% vs17.9%)。腹泻、头晕和呕吐在difelikefalin组更为常见。

研究认为,difelikefalin可改善透析患者瘙痒症状,瘙痒相关的生活质量得到改善。
