Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - ABT-493
Treatment: Drugs - ABT-530

No intervention: HCV-infected Participants - Hepatitis C virus (HCV)-infected participants who received ABT-493 and/or ABT-530 in prior Phase 2 or 3 clinical studies with these agents for the treatment of chronic HCV and were not retreated prior to entering this study. No AbbVie study drug was administered in this study.


Treatment: Drugs: ABT-493
ABT-493 was not administered in this study. This study was a follow-up for participants who received the drug in prior studies.

Treatment: Drugs: ABT-530
ABT-530 was not administered in this study. This study was a follow-up for participants who received the drug in prior studies.

Key exclusion criteria
1. The investigator considers the participant unsuitable for the study for any reasons (e.g., failure to comply with study procedures in the prior AbbVie clinical study).
2. Receipt of any investigational HCV antiviral treatment after receiving ABT-493 and/or ABT-530 in the prior study.
3. Participants who experienced non-virologic treatment failure due to premature discontinuation of study drug in prior study of ABT-493/ABT-530.
4. Participation in AbbVie's Study M15-942 protocol for re-treatment for virologic failure in the prior Phase 2 or 3 study.

Summary
Brief summary
This was a long-term follow-up study to evaluate the durability of sustained virologic response (SVR), persistence of direct-acting antiviral agent (DAA) resistance, and clinical outcomes for participants who received glecaprevir (ABT-493) and/or pibrentasvir (ABT-530) in prior AbbVie Phase 2 or 3 clinical studies for the treatment of chronic hepatitis C virus (HCV) infection.
