A Study to Evaluate ABT-450 With Ritonavir (ABT-450/r) and ABT-267 in Japanese Adults With Chronic Hepatitis C Virus Infection

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).
