心脏复极毒性(QT间期延长及尖端扭转型室性心动过速)是严重而广泛的不良反应,撤市的药物中1/3由于药物致心律失常不良反应导致。
-
抑制hERG钾通道,是致心律失常毒性的主要原因。2005年颁布的ICHS7B要求所有申报阶段的供试品必须有对hERG抑制率的数据,cF DA(NMPA)的“药物QT间期延长潜在作用非临床研究技术指导原则”(2014)也有相应规定。 、
-
hERG作为评价药物致心律失常毒性的主要指标,敏感性和特异性都存在比较严重的问题,因此,2013年FDA开始推动综合性体外致心律失常评 价(CiPA, Comprehensive in vitro Proarrhythmia Assay)。
-
CiPA包括四个核心环节:(1)心脏多种离子通道评价(2)动作电位的计算机虚拟重建(3)iPSC诱导分化心肌细胞模型(4)临床心电图评 估。
-
ICH关于CiPA的时间计划表:2020年6月,将以ICHS7B Q&A的更新形式推出。
