Reporting Groups
  Description
Daclatasvir (20 mg) + Peg-interferon Alfa-2a + Ribavirin Participants received daclatasvir tablets 20 mg orally, once daily with pegylated-interferon alfa-2a solution for injection 180 µg per 0.5 mL subcutaneously, once weekly, and ribavirin tablets 1000-1200 mg orally, twice daily for a total duration of 12 weeks. After Week 12, additional treatment was provided with interferon and ribavirin for a total of 24 or 48 weeks of therapy depending on whether or not the participant achieved an on-treatment response as defined in protocol.
Daclatasvir (60 mg) + Peg-interferon Alfa-2a + Ribavirin Participants received daclatasvir tablets 60 mg orally, once daily with pegylated-interferon alfa-2a solution for injection 180 µg per 0.5 mL subcutaneously, once weekly, and ribavirin tablets 1000-1200 mg orally, twice daily for a total duration of 12 weeks. After Week 12, additional treatment was provided with interferon and ribavirin for a total of 24 or 48 weeks of therapy depending on whether or not the participant achieved an on-treatment response as defined in protocol.
Placebo + Peg-interferon Alfa-2a + Ribavirin Participants received placebo matched with daclatasvir tablets orally, once daily with pegylated-interferon alfa-2a solution for injection 180 µg per 0.5 mL subcutaneously, once weekly, and ribavirin tablets 1000-1200 mg orally, twice daily, for a total duration of 24 weeks and pegylated-interferon alfa-2a and ribavirin, for a total duration of 48 weeks.
