3-DAA ± RBV for 12 or 24 weeksExperimental3-DAA (ombitasvir/paritaprevir/ritonavir [25 mg/150 mg/100 mg once daily] and dasabuvir [250 mg twice daily]) with or without weight-based ribavirin (± RBV; dosed 1,000 or 1,200 mg daily divided twice a day) for 12 or 24 weeks, dosed as per label based on genotype and presence of cirrhosis.

What is being measured

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

  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 study drug. Participants with missing data after backwards imputation were imputed as nonresponders.

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

Secondary outcomes (3)
  1. Percentage of Participants With Virologic Failure During Treatment

    On-treatment virologic failure was defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during treatment, or HCV RNA ≥ LLOQ at end of treatment.

    Measured: up to 12 weeks (for 12-week treatment group) or up to 24 weeks (for 24-week treatment group

  2. 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 who completed 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 study drug

  3. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) Among Participants With Ongoing Psychiatric Disorders

    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 study drug. Participants with missing data after backwards imputation were imputed as nonresponders.

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

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ombitasvir/paritaprevir/ritonavir and dasabuvir and Ribavirin in people with Chronic Hepatitis C and Cirrhosis, 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 3 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 16 Oct 2017. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 30 Aug 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?

Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) (time frame: 12 weeks after the last actual dose of study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Oct 2017.
