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 (SVR) 12 Weeks After Discontinuation of Therapy (SVR12)

    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) at 12 weeks after stopping study treatment.

    Measured: Posttreatment Week 12

  2. Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event

    Measured: Up to 24 weeks

Secondary outcomes (6)

  1. Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)

    SVR4 and SVR 24 were defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.

    Measured: Posttreatment Weeks 4 and 24

  2. Percentage of Participants With HCV RNA < LLOQ at Weeks 1, 2, 4, 8, 12, 16, 20, and 24

    Measured: Weeks 1, 2, 4, 8, 12, 16, 20, and 24

  3. HCV RNA at Weeks 1, 2, 4, 8, and 12

    Measured: Weeks 1, 2, 4, 8, and 12

  4. Change From Baseline in HCV RNA at Weeks 1, 2, 4, 8, and 12

    Measured: Baseline; Weeks 1, 2, 4, 8, and 12

  5. Percentage of Participants Experiencing On-Treatment Virologic Failure

    On-treatment virologic failure was defined as:

    • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while on treatment), or
    • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
    • Non-response (HCV RNA persistently ≥ LLOQ through 8 weeks of treatment)

    Measured: Up to 24 weeks

  6. Percentage of Participants Experiencing Viral Relapse

    Viral relapse is defined as HCV RNA ≥ LLOQ during the post-treatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available post-treatment measurement.

    Measured: Up to Posttreatment Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SOF, RBV and Peg-IFN in people with Hepatitis C, run by Gilead Sciences at 78 sites in 5 countries.

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 10 inclusion and 12 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 20 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 78 sites in United Kingdom, United States, Canada, Australia, New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.

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 5 Feb 2016). 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 (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) (time frame: Posttreatment Week 12). The study lists 2 primary outcomes in all. 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 NCT01962441, which also lists 1 linked publication.

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 20 Jun 2017; AzTrials last refreshed its copy on 31 Oct 2026.
