NS3/4A protease inhibitor
Other Name: ACH-0141625

Drug: ACH-3102
NS5A inhibitor

Drug: RBV
Other Name: Ribavirin

Placebo Comparator: Placebo
Placebo for Sovaprevir capsule QD + placebo for ACH-3102 150 mg loading dose on Day 1 followed by 50 mg capsule QD + placebo for weight-based RBV QD for 12 weeks
Drug: Placebo

Primary Outcome Measures :
  1. Incidence of Sustained Virologic Response 4 Weeks (SVR4) After the Completion of Treatment. [ Time Frame: Four weeks after the completion of treatment ]
    Incidence of SVR4 after the completion of dosing, reported as HCV RNA less than the lower limit of quantification (<LLOQ), in subjects who received active treatment (sovaprevir and ACH-0143102 in combination with ribavirin) as compared to those who received placebo.

  2. Safety and Tolerability of 12 Weeks of Sovaprevir and 3102 in Combination With Ribavirin in Subjects With Chronic Hepatitis C Genotype 1 Viral Infection. [ Time Frame: 12 weeks ]
    To determine safety and tolerability of 12 weeks of sovaprevir/ACH-0143102/RBV in subjects with chronic hepatitis C genotype 1, the following criteria will be used: the number of subjects with discontinuations due to AEs, treatment emergent G3/G4 AEs, treatment emergent G3/G4 laboratory abnormalities, clinically significant ECGs.
