  • Outcome Measures

    Primary Outcome Measures

    1. Percentage of Participants Achieving SVR12 (Sustained Virologic Response 12 Weeks After the End of All Study Therapy) [Up to Week 28]

      The percentage of participants achieving SVR12 (i.e., HCV ribnonucleic acid [RNA] < Lower Limit of Quantification [LLOQ] 12 weeks after completing study treatment) was determined. Plasma HCV RNA levels were determined with the COBAS™ AmpliPrep/COBAS™ Taqman™ HCV Test, v2.0 ® assay, which has a LLOQ of 15 IU/mL.

    2. Percentage of Participants Experiencing an Adverse Event (AE) [Up to 18 weeks (up to 2 weeks after completion of study treatment)]

      An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

    3. Percentage of Participants Discontinuing From Study Therapy Due to an AE [Up to 16 weeks]

      An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

    Secondary Outcome Measures

    1. Percentage of Participants Achieving SVR24 (Sustained Virologic Response 24 Weeks After the End of All Study Therapy) [Up to Week 40]

      The percentage of participants achieving SVR24 (i.e., HCV RNA < LLOQ 24 weeks after completing study treatment) was determined. Plasma HCV RNA levels were determined with the COBAS™ AmpliPrep/COBAS™ Taqman™ HCV Test, v2.0 ® assay, which has a LLOQ of 15 IU/mL.
