Sofosbuvir–velpatasvir–voxilaprevir 治疗12周可有效提高先前DAA治疗失败的各型HCV感染者的治愈率

抗病毒药物(DAAs)治疗后未达到持续性病毒应答(SVR)的慢性丙型肝炎病毒(HCV)感染患者其治疗选择很有限。

近日研究人员开展了2项III期临床研究,其参与者是经抗病毒治疗失败的HCV感染者。POLARIS-1研究中,先前接受过含NS5A抑制剂治疗的I型HCV患者随机接受核苷酸聚合酶抑制剂sofosbuvir、NS5A抑制剂velpatasvir和蛋白酶抑制剂voxilaprevir(n=150)或安慰剂(n=150),每天一次持续12周。POLARIS-4研究中,先前接受过除NS5A抑制剂的DAA治疗的I-III型HCV感染者,随机接受sofosbuvir–velpatasvir–voxilaprevir(n=163)或sofosbuvir–velpatasvir(n=151),持续12周,额外的19名IV型HCV感染者进入 sofosbuvir–velpatasvir–voxilaprevir治疗组。3D药物治疗组有46%的患者有代偿性肝硬化。

POLARIS-1研究中,3D疗法的持续性病毒应答率(SVR)为96%,安慰剂SVR为0;POLARIS-4中3D疗法SVR为98%,2D疗法为90%。最常见的不良事件为头痛、疲劳、腹泻和恶心。在两项试验治疗组中,因不良事件而停止治疗的患者比例低于1%。

研究表明Sofosbuvir–velpatasvir–voxilaprevir 治疗12周可有效提高先前DAA治疗失败的各型HCV感染者的治愈率。
