勃林格殷格翰(Boehringer Ingelheim)3月6日公布了III期STARTVerso-4研究中实验性丙肝药物faldaprevir用于治疗丙型肝炎病毒和艾滋病毒(HCV/HIV)合并感染患者的积极数据。 STARTVerso-4研究共招募了308例HCV初治或经历了HCV/HIV合并感染的患者,旨在调查faldaprevir与聚乙二醇化干扰素和利巴韦林(PegIFN/RBV)联合用

勃林格殷格翰(Boehringer Ingelheim)3月6日公布了III期STARTVerso-4研究中实验性丙肝药物faldaprevir用于治疗丙型肝炎病毒和艾滋病毒(HCV/HIV)合并感染患者的积极数据。

STARTVerso-4研究共招募了308例HCV初治或经历了HCV/HIV合并感染的患者,旨在调查faldaprevir与聚乙二醇化干扰素和利巴韦林(PegIFN/RBV)联合用药的疗效和安全性。研究中调查了faldaprevir的2种剂量(120mg和240mg),数据表明,全部患者在治疗结束后12周的丙型肝炎病毒治愈率(SVR12)达到了72%。此外,全部患者中有80%符合条件随机分配进入缩短的持续治疗期(24周 vs 48周),因为这些患者实现了方案定义(protocol-defined)的早期治疗成功(ETS),这些患者中有86%实现SVR12。

研究中,faldaprevir 120mg剂量组和240mg剂量组分别有71%和72%的患者实现了SVR12。SVR12数据在全部治疗组一致,且与HCV基因型1亚型(GT1a或GT1b)、存在代偿性肝硬化、faldaprevir剂量及持续时间、PegIFN/RBV持续时间均无关。一项事后分析(post hoc analysis)表明,携带Q80K变异的群体中有75%的患者实现SVR12,未携带该变异的群体有71%实现SVR12。

严重不良事件(AEs)共报告32例(10%)。到目前为止,有24名患者因不良事件停止faldaprevir治疗。研究中,最常见的不良事件为恶心、疲劳、腹泻、头痛和乏力。结束治疗后所有患者将随访24周(SVR24)。

此外,勃林格还公布了faldaprevir与常规HIV药物相互作用的分析数据,包括依非韦伦(efavirenz),阿扎那韦/利托那韦(atazanavir/ritonavir),达芦那韦/利托那韦(darunavir/ritonavir),拉替拉韦(raltegravir)和替诺福韦(tenofovir)。分析结果表明,faldaprevir对这些常规HIV药物的药代动力学无临床相关的影响。目前,STARTVero-4研究中的患者,已经正在接受ritonavir增效的HIV蛋白酶抑制剂(达芦那韦/利托那韦,120mg faldaprevir治疗组)或依非韦伦(240mg faldaprevir治疗组)治疗。

关于faldaprevir:

faldaprevir是一种强效的新一代口服HCV NS3/A4蛋白酶抑制剂,目前正开发与聚乙二醇干扰素和利巴韦林(PegIFN/RBV)联合用于广泛的基因型1(GT-1)丙型肝炎群体的治疗,包括难治性群体,如HCV-HIV共感染群体及晚期肝病群体。
