Brief summary: The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT- 267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1a (HCV GT1a) infection without cirrhosis.

Detailed description: A randomized, double-blind, placebo-controlled, multicenter study to evaluate the safety and antiviral activity of the combination of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267) and ABT-333 with and without ribavirin (RBV) in treatment-naive, noncirrhotic participants with chronic hepatitis C virus genotype 1a (HCV GT1a) infection.

Eligibility criteria: 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 1a-infection (HCV RNA level greater than or equal to 10,000 IU/mL at screening)
* Subject has never received antiviral treatment for hepatitis C infection
* No evidence of liver cirrhosis

Exclusion Criteria:

* Significant liver disease with any cause other than HCV as the primary cause
* Positive hepatitis B surface antigen or anti-human immunodeficiency virus antibody
* Positive screen for drugs or alcohol
* Significant sensitivity to any drug
* Use of contraindicated medications within 2 weeks of dosing
* Abnormal laboratory tests
