Primary Outcome Measures
Change in Interferon (IFN)-Stimulated Genes (ISG) Expression in Peripheral Blood Mononucleated Cells (PBMCs) for Participants Achieving SVR12
[ Time Frame: Week 0 to Post-Treatment Week 12 ]
The changes from week 0 to post-treatment (PT) week 12 in key ISG expression in PBMCs for participants achieving sustained virologic response 12 weeks PT (SVR12) where SVR12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification (

Ombitasvir/paritaprevir/ritonavir + dasabuvir + RBV
Ombitasvir/paritaprevir/ritonavir (25 mg/150 mg/100 mg once daily [QD]) + dasabuvir (250 mg twice daily [BID]) + weight based Ribavirin (RBV; dosed 1,000 or 1,200 mg daily divided BID)
Other Name: ABT-267/ABT-450/ritonavir
Other Name: ABT-333
A study to evaluate the role of ombitasvir/paritaprevir/ritonavir and dasabuvir coadministered with RBV treatment leading to sustained virologic response 12 weeks post-dosing (SVR12) on the changes from baseline in IFN-stimulated gene (ISG) expression in peripheral blood mononucleated cells (PBMCs) in HCV GT 1a-infected adult participants.Eligibility
|Ages Eligible for Study:||18 Years to 100 Years|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Screening laboratory result indicating hepatitis C viral (HCV) genotype (GT) 1a infection.
- Chronic HCV infection.
- Participants must be non-cirrhotic.
- Participants must be treatment-naïve or have documentation that they were adherent to prior pegIFN/RBV combination therapy and meet the criteria of prior pegylated-interferon (pegIFN)/ribavirin (RBV) treatment failure.
- Participants must meet specific human leukocyte antigen (HLA) allele requirements.
- Women who are pregnant or breastfeeding.
- Positive test result for hepatitis B surface antigen (HBsAg) or anti-human immunodeficiency virus antibody (HIV Ab) positive immunoassay.
- Clinically significant abnormalities or co-morbidities, other than HCV infection, that make the subject unsuitable for this study or treatment.
- Current enrollment in another interventional clinical study, previous enrollment in this study, prior or current use of any investigational or commercially available anti-HCV agents other than pegIFN or RBV (including previous exposure to paritaprevir, ombitasvir, or dasabuvir), or receipt of any investigational product within 6 weeks prior to study drug administration.
- History of solid organ transplant.
- Screening laboratory analysis that shows abnormal results.
