Brief summary:
This is a study of combination direct-acting antiviral agents (DAA) with or without ribavirin (RBV) in patients with chronic Hepatitis C Virus (HCV).

Detailed description:
A study to evaluate the safety and effectiveness of experimental drugs ABT-450, ABT-267 (also known as ombitasvir), ABT-333 (also known as dasabuvir), ritonavir, and ribavirin in participants with HCV. The study will test the safety and effects of combinations of these drugs in treatments up to 24 weeks.
