What is being measured

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

  1. Sustained virologic response (SVR)

    Sustained virologic response (SVR, defined as plasma HCV RNA < lower limit of quantification [LLoQ] at 24 weeks after treatment cessation) following treatment with GS-5885 + GS-9451 + PEG/RBV for 6 or 12 weeks, or PEG/RBV for 24 weeks in IL28B CC subjects.

    Measured: 30 , 36 or 48 weeks

Secondary outcomes (4)
  1. Safety and tolerability of therapy

    Safety and tolerability of the therapy is measured by frequency of laboratory abnormalities , reported adverse events and discontinuations due to adverse events.

    Measured: Up to 48 weeks

  2. Virologic response

    Virologic response at Weeks 2, 4, 6, 8, 10, and 12 (depending on treatment arm) as measured by the rates of HCV RNA < LLoQ and viral breakthrough and relapse

    Measured: Weeks 2, 4, 6, 8, 10, and 12

  3. Compare SVR

    Compare SVR following treatment with GS-5885 + GS-9451 + PEG/RBV for 6 weeks versus 12 weeks.

    Measured: Weeks 30 and 36

  4. Viral resistance

    Characterize viral resistance to GS-5885 and GS-9451 when administered in combination with PEG/RBV

    Measured: Up to 96 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GS-5885, GS-9451 and RBV in people with Chronic Hepatitis C, run by Gilead Sciences at 55 sites in 4 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 11 inclusion and 4 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: stopped early, as of the sponsor's last update on 3 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 55 sites in United States, Australia, Canada, 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 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?

The study was stopped early. Results are not available in the source record.

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?

Sustained virologic response (SVR) (time frame: 30 , 36 or 48 weeks). 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 3 Feb 2014.
