What is being measured
The primary outcome is the main question the study is designed to answer.
Sustained virologic response (SVR) defined as undetectable HCV RNA 24 weeks after treatment cessation
Measured: 24 weeks of off-treatment follow-up
Secondary outcomes (4)
Safety and tolerability of therapy as measured by frequency of laboratory abnormalities, reported adverse events, and discontinuations due to adverse events
Measured: Through up to 48 weeks treatment period and 24 weeks of off-treatment follow-up
Emergence of viral resistance following initiation of therapy with GS-9190 and GS-9256
Measured: Through up to 48 weeks treatment period, 24 weeks of off-treatment follow-up, and up to 48 weeks of follow-up in the Resistance Registry Substudy
Viral dynamics and steady state pharmacokinetics of GS-9190 and GS-9256 when administered in combination with PEG and RBV; measured by HCV RNA levels and plasma concentrations of GS-9190 and GS-9256 over time
Measured: Through Week 4 of therapy
Long-term assessment of plasma HCV RNA in subjects who achieve SVR
Plasma HCV RNA will be measured at approximately 6, 12, 24, and 36 months after Week 72.
Measured: 36 months following Week 72

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GS-9190, GS-9256 and Pegasys® in people with Chronic Hepatitis C Infection, run by Gilead Sciences at 114 sites in 11 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 9 inclusion and 13 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 28 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 114 sites in United States, Poland, Germany, Canada, United Kingdom and 6 more countries. 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. Some participants in this study may receive a placebo. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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) defined as undetectable HCV RNA 24 weeks after treatment cessation (time frame: 24 weeks of off-treatment follow-up). 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 28 Jan 2014.
