The purpose of this study is to compare the sustained virologic response at post treatment Week 12 for each cohort (BMS-790052/Pegylated-interferon alfa 2a (pegIFNα-2a)/Ribavirin (RBV) versus placebo/PegIFNα-2a/RBV).
Name: BMS-790052 (NS5A Replication Complex Inhibitor)
Name: Placebo matching BMS-790052
Name: Pegylated-interferon alfa 2a
Name: Ribavirin
Description: 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.
Measure: Percentage of Participants With 12 Week Sustained Virologic Response (SVR12) Time: Week 12 (Follow-up period)Description: 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.
Measure: Percentage of Participants Who Achieve HCV Ribonucleic Acid (RNA) < Limit of Quantification (LLOQ) Time: Treatment Weeks 1, 2, 4, 6, 8 and 12; Weeks 4 and 12; End of treatment (EOT); Post treatment Week 24; Post treatment Week 48Description: 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.
Measure: Percentage of Participants With Undetectable Hepatitis C Virus (HCV) RNA Levels Time: Treatment Weeks 1, 2, 4, 6, 8 and 12; Weeks 4 and 12, End of treatment (EOT), Post treatment Week 24, Post treatment Week 48Description: 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.
Measure: 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 Gene Time: Post Treatment Weeks 12, 24Description: 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.
Measure: Number of Participants With Serious Adverse Events (SAEs), Discontinuations Due to Adverse Events (AEs) and Who Died Time: From Day 1 (start of study treatment) up to Follow-up Week 4Allocation: Randomized
Parallel Assignment
