2012年4月20日,百时美施贵宝(Bristol-Myers Squibb)公司的双重直接作用抗病毒(dual direct-acting antiviral,DAA)疗法(daclatasvir和asunaprevir)在1b型HCV患者中显示出持续病毒学应答(sustained virologic response,SVR)。

Daclatasvir是一种研究性NS5A复制复合物抑制剂,而asunaprevir是一种研究性NS3蛋白酶抑制剂。

在一项II期开放标签临床试验(AI447-017)中,HCV患者被分为2组:A组由21名1b型先前无应答患者(prior null responders)组成,B组则由22名1b型医学上不符合聚乙二醇干扰素和利巴韦林治疗(alfa/RBV)或先前对alfa/RBV不耐受的患者组成。

该项研究的主要目的是调查接受治疗后达到第12周持续病毒学反应(sustained virologic response 12-weeks following treatment,SVR12)的患者比例。

该II期试验中,合计有77%的患者达到了SVR12。此外,在A组和B组中,分别有91%和64%的患者达到了SVR24。
