The purpose of this study is to assess the safety and efficacy of daclatasvir and simeprevir with and without ribavirin for genotype 1 chronic hepatitis C virus infection in patients who are treatment-naive or null responders to previous pegylated interferon/ribavirin therapy.
Name: Daclatasvir
Name: Simeprevir
Name: Ribavirin
Description: SVR12 rate was defined as hepatitis C virus (HCV) RNA levels to be
Description: RVR was defined as hepatitis C virus (HCV) RNA levels to be
Description: cEVR was defined as hepatitis C virus (HCV) RNA levels to be
Description: eRVR were defined as hepatitis C virus (HCV) RNA levels to be
Description: EOTR were defined as hepatitis C virus (HCV) RNA levels
Description: Participants were categorized into 3 genotypes based on single nucleotide polymorphisms in the IL28B gene. SVR12 was defined as hepatitis C virus (HCV) RNA levels below lower limit of quantitation, 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.
Measure: Percentage of Participants With Sustained Virologic Response at Week 12 (SVR12) by rs12979860 Single Nucleotide Polymorphisms in the IL-28B Gene Categories Time: Baseline, post-treatment Week 12 (Follow-up period)Description: 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. Based on the severity, AEs were categorized as Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4=Life-threatening or disabling, Gr 5=Death.
Measure: Number of Participants With Serious Adverse Events (SAEs) and Discontinuations Due to Adverse Events (AEs) and Who Died Time: From start of treatment (Day 1) up to 7 days post last dose of study treatment (Week 24)Allocation: Randomized
