Primary Outcome Measures
NameTimeMethod
Percentage of Treatment-Experienced Participants With Sustained Virologic Response at Follow-up Week 12 (SVR12) Target Detected (TD) or Target Not Detected (TND)Week 12 (Follow-up period)

SVR12 was defined as hepatitis C virus (HCV) RNA less than the lower limit of quantitation ie., 25 IU/mL, target detected or target not detected at follow-up Week 12. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Treatment-Naive Participants With Sustained Virologic Response at Follow-up Week 12 (SVR12) Target Detected (TD) or Target Not Detected (TND)Week 12 (Follow-up period)

SVR12 was defined as hepatitis C virus (HCV) RNA less than the lower limit of quantitation ie., 25 IU/mL, TD or TND at follow-up Week 12. HCV RNA levels were measured by the Roche Cobas® TaqMan® HCV Test version 2.0 from the central laboratory.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With CC or Non-CC Genotype at the IL28B rs12979860 Single Nucleotide Polymorphisms (SNPs) Who Achieved Sustained Virologic Response After 12 Weeks of Follow-up (SVR12)Week 12 (Follow-up period)

Participants categorized into 2 genotypes (CC and non-CC) based on SNPs in the IL28B gene were assessed for SVR12, defined as response in which hepatitis C virus (HCV) RNA levels below lower limit of quantitation (LLOQ) below target detected or target not detected at follow-up Week 12 (LLOQ: 25 IU/mL). HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Participants Who Achieved Hepatitis C Virus (HCV) RNA Levels Less Than the Lower Limit of Quantitation (LLOQ)- Target Detected (TD) or Target Not Detected (TND)Week 1, 2, 4, 6, 8, 12, End of treatment (treatment period), Week 4 (follow-up period), Week 24 (follow-up period)

Percentage of participants who achieved HCV RNA \<LLOQ,TD or TND was determined (LLOQ: 25 IU/mL). HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Participants With Or Without Cirrhosis at Baseline Who Achieved Sustained Virologic Response at Follow-up Week 12 (SVR12)Baseline, Week 12 (Follow-up period)

SVR12 was defined as hepatitis C virus (HCV) RNA less than the lower limit of quantitation ie. 25 IU/mL, target detected or target not detected at follow-up Week 12. Cirrhosis was considered a negative predictor of SVR in participants treated with an interferon formulation or ribavirin. Presence or absence of cirrhosis was determined at baseline and follow-up Week 12 in the participants to evaluate the post-treatment relapse.

Number of Participants With Serious Adverse Events (SAEs) and Discontinuations Due to Adverse Events (AEs)From Day 1 first dose to last dose plus 7 days

AE was defined as any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization.

Percentage of Participants With Rapid Virologic Response at Week 4 (RVR) Target Not Detected (TND)Week 4

RVR was defined as hepatitis C virus RNA levels to be \< lower limit of quantitation ie, 25 IU/mL TND at Week 4. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Participants With Complete Early Virologic Response (cEVR) Target Not Detected (TND)Week 12

cEVR was defined as hepatitis C virus RNA levels to be \< lower limit of quantitation ie, 25 IU/mL TND at Week 12. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Participants With End of Treatment Response (EOTR) Target Not Detected (TND)Up to the end of treatment (up to 24 weeks)

EOTR were defined as hepatitis C virus RNA levels to be \< lower limit of quantitation ie, 25 IU/mL TND at end of treatment. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

Percentage of Participants Who Achieved Hepatitis C Virus (HCV) RNA Levels Less Than the Lower Limit of Quantitation (LLOQ) - Target Not Detected (TND)Week 1, 2, 6, 8 (treatment period)

Percentage of participants who achieved HCV RNA \<LLOQ, TND was determined (LLOQ: 25 IU/mL). HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.
