What is being measured

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

  1. Slope of the Second Phase Decline in Plasma HCV Ribonucleic Acid (RNA) Levels During Treatment

    HCV viral kinetics in plasma during therapy were modeled through non-linear mixed effect models, including a rapid first phase of initial decline and a slower second phase decline. The slope of the second phase decline was estimated for each treatment arm.

    Measured: From Week 0 to Week 2

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ombitasvir/ABT-450/Ritonavir, Dasabuvir and Ribavirin (RBV) in people with Chronic Hepatitis C and Hepatitis C (HCV), 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 6 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 31 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 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 15 May 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?

Slope of the Second Phase Decline in Plasma HCV Ribonucleic Acid (RNA) Levels During Treatment (time frame: From Week 0 to Week 2). 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 31 Oct 2017.
