Primary outcomePrimary: Percentage of Participants With Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Suppressed Below the Lower Limit of Detection (LLOD) From Week 4 Through Week 12 — 89.5; 78.6; 58.8 percentage of participants — p=0.547
Summary
The purpose of this study is to evaluate the antiviral activity, safety, and pharmacokinetics of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-333 (also known as dasabuvir) and ribavirin (RBV) in treatment-naïve and non responder participants with genotype 1 chronic hepatitis C virus (HCV) infection.
