Primary Outcome Measures:
  • 12 week antiviral efficacy after 24 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Sustained virologic response 12 weeks after discontinuation of therapy (SVR12 defined as HCV RNA < lower limit of quantification(LLoQ) 12 weeks after last dose of study drug).


Secondary Outcome Measures:
  • Evaluation of Safety and Tolerability after 24 weeks of treatment [ Time Frame: Safety and Tolerability on treatment and 30 days post last dose ] [ Designated as safety issue: No ]
    Assess safety laboratory tests and the number, frequency and severity of adverse events through 30 days post last dose of study drug
