Daclatasvir plus asunaprevir (DCV + ASV) has demonstrated potent antiviral activity in patients with hepatitis C virus (HCV) genotype 1b infection. A definite conclusion about efficacy and safety of DCV + ASV in patients with HCV genotype 1b is not available. A meta-analysis was conducted to evaluate outcomes of all-oral treatment with DCV + ASV in terms of sustained virological response at 12 (SVR12) and 24 (SVR24) weeks and adverse effects after the end of treatment.
