Inclusion Criteria:
- Females must be practicing specific forms of birth control on study treatment, or be post-menopausal for more than 2 years or surgically sterile
- Chronic hepatitis C, genotype 1b (HCV-GT1b) or genotype 2 (HCV GT2) infection (HCV RNA level greater than 10,000 IU/mL at screening) previously treated with pegylated interferon/ribavirin (pegIFN/RBV).
- Subject's hepatitis C virus genotype is subgenotype 1b and subject was a null responder or partial responder, OR
- Subject's hepatitis C virus genotype is subgenotype 2 and subject was a null responder, partial responder, or relapser (Null responder: received at least 10 weeks of pegIFN/RBV for the treatment of HCV and failed to achieve a 2 log10 IU/mL reduction in HCV RNA at Week 12; Partial responders: received at least 20 weeks of pegIFN/RBV for the treatment of HCV and achieved ≥ 2 log10 IU/mL reduction in HCV RNA at Week 12, but failed to achieve HCV RNA undetectable (HCV RNA < lower limit of detection [< LLOD]) at the end of treatment; Relapsers: received at least 1 course of pegIFN/RBV for the treatment of HCV and was undetectable at the end of treatment, but HCV RNA was detectable within 24 weeks of treatment follow-up).
Exclusion Criteria:
- Significant liver disease with any cause other than HCV as the primary cause
- Positive screen for drugs or alcohol.
- Positive hepatitis B surface antigen or anti-human immunodeficiency virus antibody.
- Use of contraindicated medications within 2 weeks of dosing
- Previous use of any investigational or commercially available anti-Hepatitis C virus agent other than pegIFN/RBV, including previous exposure to ABT-450 or ABT-267.

Percentage of Participants With Sustained Virologic Response 24 Weeks After Treatment (SVR24)
Zeitfenster: 24 weeks after last dose of study drug
|
The percentage of participants with SVR24 (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ] 24 weeks after the last dose of study drug).
The LLOQ for the assay was 25 IU/mL.
|
24 weeks after last dose of study drug

|
Number of Participants With Adverse Events (AEs)
Zeitfenster: TEAEs: up to 16 weeks for the 12-week treatment groups and up to 28 weeks for the 24-week treatment groups; SAEs: up to 65 weeks for the 12-week treatment groups and up to 77 weeks for the 24-week treatment groups.
|
An AE is any untoward medical occurrence, which does not necessarily have a causal relationship with treatment.
A serious adverse event (SAE) is an AE that results in death, is life-threatening, results in or prolongs hospitalization, results in congenital anomaly, persistent or significant disability/incapacity, spontaneous or elective abortion, or requires intervention to prevent a serious outcome.
AEs were rated for severity as either Mild: transient and easily tolerated; Moderate: causes discomfort and interrupts usual activities; or Severe: causes considerable interference with usual activities, may be incapacitating or life-threatening.
AEs related to study drug were assessed as being either probably or possibly related by the investigator.
Treatment-emergent AEs (TEAEs) were collected from the first dose of study drug administration to 30 days after last dose; SAEs were collected from the time that informed consent was obtained to 30 days after last dose.
|
TEAEs: up to 16 weeks for the 12-week treatment groups and up to 28 weeks for the 24-week treatment groups; SAEs: up to 65 weeks for the 12-week treatment groups and up to 77 weeks for the 24-week treatment groups.
