Description

Inclusion Criteria:

  • Chinese, South Korean, and Taiwanese descent with full Chinese, South Korean, and Taiwanese parentage
  • Chronic hepatitis C virus (HCV) infection prior to study enrollment.
  • Screening laboratory result indicating HCV subtype 1b (GT1b) infection.
  • Per local standard practice, documented absence of cirrhosis.
  • Participant has never received antiviral treatment (including interferon [IFN]-based therapy [alpha, beta or pegylated (peg)IFN] with or without RBV) for HCV infection (treatment-naïve participant) or participant must have documentation that they met the definition of one of the following categories (treatment experienced participant): Non-responder or Relapser
  • Participant has plasma HCV RNA level > 10,000 IU/mL at Screening.

Exclusion Criteria:

  • HCV genotype performed during screening indicating unable to genotype or infection with any HCV genotype other than GT1b.
  • Positive test result at Screening for hepatitis B surface antigen (HBsAg), or hepatitis B virus DNA (HBV-DNA) > Lower Limit of Quantification (LLOQ) if HBsAg negative, or anti-human immunodeficiency virus antibody (HIV Ab) positive.
  • Any current or past clinical evidence of cirrhosis.
  • Any primary cause of liver disease other than chronic HCV infection.
  • Screening laboratory analyses showing abnormal kidney, hepatic, or hematologic function.
  • Use of known strong inducers of cytochrome P450 3A (CYP3A) or strong inhibitors of cytochrome P450 3A (CYP2C8) within 2 weeks or within 10 half-lives, whichever is longer, of the respective medication/supplement prior to study drug administration.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
Time Frame: 12 weeks after the last actual dose of active study drug
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of active study drug. The primary efficacy endpoint was superiority of the percentage of treatment-naïve and treatment-experienced HCV subgenotype 1b (GT1b)-infected participants treated with 3-DAA (ombitasvir/paritaprevir/ritonavir [25 mg/150 mg/100 once daily] and dasabuvir [250 mg twice daily]) who achieved SVR12 compared with the historical control rate for comparable patients treated with telaprevir (TVR) plus pegylated interferon (pegIFN) and RBV.
12 weeks after the last actual dose of active study drug
Percentage of Participants With Sustained Virologic Response 24 Weeks Post-treatment (SVR24)
Time Frame: 24 weeks after the last actual dose of active study drug
SVR24 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of active study drug. The primary efficacy endpoint was superiority of the percentage of treatment-naïve and treatment-experienced HCV subgenotype 1b (GT1b)-infected participants treated with 3-DAA (ombitasvir/paritaprevir/ritonavir [25 mg/150 mg/100 once daily] and dasabuvir [250 mg twice daily]) who achieved SVR24 compared with the historical control rate for comparable patients treated with telaprevir (TVR) plus pegylated interferon (pegIFN) and RBV.
24 weeks after the last actual dose of active study drug

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With On-treatment Virologic Failure
Time Frame: up to 12 weeks
On-treatment virologic failure was defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during active treatment; confirmed increase of > 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline in HCV RNA during active treatment; or all on-treatment values of HCV RNA ≥ LLOQ with at least 6 weeks of active treatment.
up to 12 weeks
Percentage of Participants With Post-treatment Relapse by Post-treatment Week 12
Time Frame: From the end of treatment through 12 weeks after the last dose of active study drug
Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of active study drug among participants who completed treatment with HCV RNA levels < LLOQ at the end of treatment.
From the end of treatment through 12 weeks after the last dose of active study drug
Percentage of Participants With Post-treatment Relapse by Post-treatment Week 24
Time Frame: From the end of treatment through 24 weeks after the last dose of active study drug
Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 24 weeks after the last dose of active study drug among participants who completed treatment with HCV RNA levels < LLOQ at the end of treatment.
From the end of treatment through 24 weeks after the last dose of active study drug
