Ombitasvir/ABT-450 (Paritaprevir)/Ritonavir With Dasabuvir and Ribavirin (RBV) in Treatment Naive and Treatment Experienced Genotype 1a Hepatitis C Virus Infected Adults

September 5, 2017 updated by: AbbVie

An Exploratory Study to Evaluate Immune Restoration Following Removal of Viral Antigen in Treatment-Naïve and Treatment-Experienced Adults With Genotype (GT) 1a Chronic Hepatitis C Virus (HCV) Infection Administered Ombitasvir/ ABT-450/Ritonavir With Dasabuvir and Ribavirin (RBV) for 12 Weeks

A study to evaluate immune restoration following removal of viral antigen in non-cirrhotic hepatitis C virus (HCV) genotype (GT) 1a treatment-naïve and pegylated-interferon (pegIFN)/ribavirin (RBV) treatment-experienced adults receiving treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir coadministered with ribavirin (RBV) for 12 weeks.

Detailed Description

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.

Description

Inclusion Criteria:

  1. Screening laboratory result indicating hepatitis C viral (HCV) genotype (GT) 1a infection.
  2. Chronic HCV infection.
  3. Participants must be non-cirrhotic.
  4. 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.
  5. Participants must meet specific human leukocyte antigen (HLA) allele requirements.

Exclusion Criteria:

  1. Women who are pregnant or breastfeeding.
  2. Positive test result for hepatitis B surface antigen (HBsAg) or anti-human immunodeficiency virus antibody (HIV Ab) positive immunoassay.
  3. Clinically significant abnormalities or co-morbidities, other than HCV infection, that make the subject unsuitable for this study or treatment.
  4. 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.
  5. History of solid organ transplant.
  6. Screening laboratory analysis that shows abnormal results.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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 (<LLOQ) 12 weeks after the last dose of study drug. For each key ISG, fold change was defined as the ratio of the difference between PT Week 12 and baseline expressions over the baseline expression.
Week 0 to Post-Treatment Week 12
