Brief summary: The purpose of this study is to evaluate the safety and efficacy of ABT-450, ritonavir and ABT-267 (ABT-450/r/ABT-267; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) co-administered with ribavirin (RBV) in hepatitis C virus genotype 1 infected treatment-experienced adults.


Eligibility criteria: Inclusion Criteria:

* Females must be post-menopausal for at least 2 years or surgically sterile or practicing specific forms of birth control.
* Chronic hepatitis C, genotype 1 infection and HCV RNA level greater than 10,000 IU/mL at screening.
* Previous treatment failure of peg-interferon and ribavirin (pegIFN and RBV).
* No evidence of liver cirrhosis.

Exclusion Criteria:

* Positive screen for drugs or alcohol.
* Significant sensitivity to any drug.
* Use of contraindicated medications within 2 weeks of dosing.
* Certain predefined abnormal laboratory tests.
* Positive hepatitis B surface antigen or anti-human immunodeficiency virus antibody.
