What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximal Decrease From Baseline in log10 HCV RNA Levels During ABT-493 or ABT-530 Monotherapy Treatment

    Maximal decrease from baseline in log10 HCV RNA levels during ABT-493 or ABT-530 monotherapy treatment. The baseline value was the last measurement before the first dose of monotherapy on Day 1.

    Measured: Day 1 through prior to first dose of the combination regimen on Study Day 4

Secondary outcomes (3)
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)

    SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of combination study drug.

    Measured: 12 weeks after last actual dose of combination study drug

  2. Percentage of Participants With On-treatment Virologic Failure

    On-treatment virologic failure was defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during combination treatment; confirmed increase of > 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline in HCV RNA during combination treatment; or HCV RNA ≥ LLOQ at end of combination treatment with at least 6 weeks of combination treatment.

    Measured: Up to 87 days

  3. Percentage of Participants With Post-treatment Relapse

    Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants completing combination treatment with HCV RNA levels < LLOQ at the end of treatment.

    Measured: From the end of treatment through 12 weeks after the last dose of combination study drug

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ABT-493, ABT-530 and ABT-450/r/ABT-267, ABT-333 in people with Chronic Hepatitis C and Hepatitis C Virus, run by AbbVie.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Oct 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximal Decrease From Baseline in log10 HCV RNA Levels During ABT-493 or ABT-530 Monotherapy Treatment (time frame: Day 1 through prior to first dose of the combination regimen on Study Day 4). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01995071, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jul 2021.
