Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
