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.

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.

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
