For those chronic hepatitis C patients, who are interferon-ineligible or intolerant, there is a burning need for the development of pan-oral interferon-free regimen. The investigators examine the efficacy and safety of sofosbuvir, a NS5B nucleotide polymerase inhibitor and daclatasvir, an NS5A replication complex inhibitor in Chinese treatment-experienced cirrhosis patients with chronic G1b infection.

At baseline, liver stiffness measurement (LSM) using transient elastography (FibroScan®) is used to assess liver fibrosis and the single nucleotide polymorphism ofinterferon-λ 3 (IL-28, rs12979860, C or T) and IFLN4 (ss469415590, TT or ΔG) is determined.
