Primary Outcome Measures
NameTimeMethod
Percentage of Participants With 12 Week Sustained Virologic Response (SVR12)Week 12 (Follow-up period)

Participants were assessed for sustained virologic response 12 weeks post treatment (SVR12) defined as hepatitis C virus (HCV) RNA levels \< lower limit of quantitation (LLOQ was 25 IU/mL), target detected (TD) or target not detected (TND) at post-treatment Week 12.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieve HCV Ribonucleic Acid (RNA) < Limit of Quantification (LLOQ)Treatment Weeks 1, 2, 4, 6, 8 and 12; Weeks 4 and 12; End of treatment (EOT); Post treatment Week 24; Post treatment Week 48

Participants who achieved HCV RNA levels below LLOQ ie, 25 international unit per milliliter (IU/mL). Participants in the placebo arm did not have visits beyond post treatment Week 24.

Percentage of Participants With Undetectable Hepatitis C Virus (HCV) RNA LevelsTreatment Weeks 1, 2, 4, 6, 8 and 12; Weeks 4 and 12, End of treatment (EOT), Post treatment Week 24, Post treatment Week 48

Participants who achieved HCV RNA undetectable ie, 10 international units per milliliter (IU/mL). Participants in the placebo arm did not have visits beyond post treatment Week 24.

Percentage of Participants With Sustained Virologic Response at Follow-up Week 12 (SVR12) or Sustained Virologic Response at Follow-up Week 24 (SVR24) by rs12979860 Single Nucleotide Polymorphism (SNP) in the IL28B GenePost Treatment Weeks 12, 24

Participants categorized into three genotypes based on SNPs in the IL28B gene were assessed for SVR12 and SVR24, defined as response in which hepatitis C virus RNA levels below lower limit of quantitation or below target detected or target not detected at follow-up Week 12 and Week 24 respectively.

Number of Participants With Serious Adverse Events (SAEs), Discontinuations Due to Adverse Events (AEs) and Who DiedFrom Day 1 (start of study treatment) up to Follow-up Week 4

AE was defined as any new unfavorable symptom, sign, or disease or worsening of a pre-existing 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, was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalisation.
