A Randomized, Double-Blind, Controlled Study to Evaluate the Efficacy and Safety of the Combination of ABT-450/Ritonavir/ABT-267 (ABT-450/r/ABT-267) and ABT-333 With and Without Ribavirin (RBV) in Treatment-Naïve Adults With Genotype 1a Chronic Hepatitis C Virus (HCV) Infection (PEARL-IV)
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.

Conditions
- Chronic Hepatitis C Infection
Interventions
- ABT-450/r/ABT-267, ABT-333
- Ribavirin
- Placebo for Ribavirin
Primary outcomes
- Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment; Primary Analyses — 12 weeks after last dose of study drug
The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid \[HCV RNA\] level less than the lower limit of quantitation \[\< LLOQ\]) 12 weeks after the last dose of study drug. The LLOQ for the assay was 25 IU/mL. The primary efficacy endpoints were noninferiority of the percentage of participants who achieved sustained virologic response 12 weeks after treatment in each treatment arm (ABT-450/r/ABT-267 and ABT-333, plus either placebo RBV or RBV) compared with the historical control rate for noncirrhotic, treatment-naïve participants with HCV GT1a infection treated with telaprevir and peginterferon(pegIFN)/RBV.
