Safety and efficacy of faldaprevir in combination with pegylated interferon α‐2b and ribavirin in Japanese patients with genotype‐1 chronic hepatitis C virus infection

Aim We evaluated the safety and efficacy of the hepatitis C virus (HCV) NS3/4A A protease inhibitor faldaprevir plus pegylated interferon α‐2b and ribavirin (PegIFNα‐2b/RBV) in Japanese patients with HCV genotype‐1 infection. Methods Treatment‐naïve patients were randomized (1:1) to faldaprevir 120 mg q.d. for 12 or 24 weeks (response‐guided therapy [RGT], n = 44), or faldaprevir 240 mg q.d. for 12 weeks (n = 43), each combined with PegIFNα‐2b/RBV for 24 or 48 weeks (RGT). Response‐guided therapy was based on early treatment success (HCV RNA
