MK-5172是HCV NS3/4蛋白酶抑制剂。MK-8742是HCV NS5A抑制剂。来自巴塞罗那的研究人员发现,MK-5172和MK-8742+/-利巴韦林(RBV)可用于治疗HCV1型和HIV共感染患者。据悉,这是第一份HCV和HIV共感染患者服用口服药物治疗的报道。 该研究人群为丙肝初治、非肝硬化合并HIV感染的患者。患者正在进行稳定的抗逆转录病毒疗法(罗特格韦+替诺福韦或阿巴卡韦)。患

MK-5172是HCV NS3/4蛋白酶抑制剂。MK-8742是HCV NS5A抑制剂。来自巴塞罗那的研究人员发现,MK-5172和MK-8742+/-利巴韦林(RBV)可用于治疗HCV1型和HIV共感染患者。据悉,这是第一份HCV和HIV共感染患者服用口服药物治疗的报道。

该研究人群为丙肝初治、非肝硬化合并HIV感染的患者。患者正在进行稳定的抗逆转录病毒疗法(罗特格韦+替诺福韦或阿巴卡韦)。患者被随机分配到MK-5172组(100mg,QD,共12周)和MK-8742组( 50mg,QD,共12周)±利巴韦林(基于体重)。用COBAS TaqMan探针法V2.0检测病人的病毒学应答(定量检测下限为<25IU/mL)。

研究共纳入了40例患者(83%为男性,20%为非裔美国人,78%为HCV基因1a型)。平均基线HCV-RNA为6.2 log10的IU/mL。治疗4周后,有22例患者的HCV-RNA < 25 IU / mL,无论有无利巴韦林治疗。

最常见的不良反应为:疲劳10%(4/ 40),头痛5%(2/ 40),背痛5%(2/ 40)和虚弱5%(2/40)。该研究目前仍在进行中。

该研究表明,HCV1型感染和HIV双重感染患者使用MK-5172和MK-8742治疗(无论有无利巴韦林),可以在头4周内取得快速抑制病毒的疗效。
