Primary Outcome Measures :
  1. Sustained virologic response (SVR) [ Time Frame: 24 weeks of off-treatment follow-up ]

Secondary Outcome Measures :
  1. Safety and tolerability [ Time Frame: through 24 weeks of off-treatment follow-up ]
    To evaluate the safety and tolerability of 30 mg or 90 mg GS-5885 when given with GS-9451, Tegobuvir and RBV for 12 or 24 weeks. Safety endpoints will be analyzed by the number and percent of subjects with events or abnormalities for categorical values or 8-number summary (n, mean, standard deviation, median, Q1, Q3, minimum, maximum) for continuous data by treatment group.

  2. HCV RNA < Lower Limit Of Quantification [ Time Frame: Weeks 1, 2, 4, 12 and 24 ]
    To evaluate the antiviral efficacy at Weeks 1, 2, 4, 12 and 24, as measured by the rates of HCV RNA < LLoQ and viral breakthrough and relapse.

  3. Rescue Therapy Substudy SVR [ Time Frame: 24 Weeks ]
    To evaluate the antiviral efficacy (as defined by SVR) of the addition of pegylated interferon (PEG) for 24 weeks to GS-5885, GS-9451, tegobuvir and RBV in subjects who experience viral breakthrough on treatment.

  4. Emergence of viral resistance [ Time Frame: 12 or 24 weeks ]
    To evaluate the emergence of viral resistance during treatment with GS-9451, Tegobuvir and RBV when given with 30 mg or 90 mg GS-5885 for 12 or 24 weeks.

  5. Viral dynamics of GS-5885, GS-9451 and Tegobuvir when administered in combination with RBV [ Time Frame: Through Week 2 of therapy ]
    HCV RNA levels, pharmacokinetics and viral sequencing

  6. Pharmacokinetics of GS-5885, GS-9451 and Tegobuvir when administered in combination with RBV [ Time Frame: Through Week 2 of therapy ]

    Pharmacokinetics (Cmax, Tmax, Clast, Tlast, Ctau, λz, AUCtau, and T½) will be listed

    and summarized for GS-5885, GS-9451 and Tegobuvir using descriptive statistics (e.g.,

    sample size, arithmetic mean, geometric mean, % coefficient of variation, standard deviation,

    median, minimum, and maximum). Plasma concentrations of the study drug over time will be

    summarized using descriptive statistics
