About this study
Official title: A Phase 2, Randomized, Open-Label Trial of GS-9256 Plus GS-9190 Alone and in Combination With Ribavirin for 28 Days in Treatment Naïve Subjects With Chronic Genotype 1 Hepatitis C Virus Infection (Protocol No. GS-US-196-0112)
This a phase 2, randomized, open-label trial of GS-9256 plus GS-9190, two oral anti HCV drugs, for 28 days with and without ribavirin (RIBA) and with pegylated interferon (PEG)/RIBA in adults with chronic Hepatitis C virus (HCV). In Part A, approximately thirty (30) subjects 18-70 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of the two treatment groups (GS-9256 plus GS-9190 or GS-9256 plus GS-9190 plus RIBA). In Part B, an additional fifteen (15) subjects will receive 75 mg GS-9256 BID plus 40 mg GS-9190 BID in combination with PEG/RIBA. After the 28-day treatment period, subjects will receive PEG/RIBA as standard of care (SOC).
Following randomization, subjects will return for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 28 day treatment phase. During the treatment phase, subjects will receive oral study drugs twice daily for 28 days and PEG once weekly for Part B. Subjects then receive PEG/RIBA as local SOC starting on Day 28 (not provided as part of the study). Following completion of the 28-day treatment phase, subjects will be followed for approximately 72 weeks.
Read the detailed description
GS-9256 (an HCV NS3 protease inhibitor) plus GS-9190 (non-nucleoside HCV NS5B inhibitor) will be administered for 28 days with and without RIBA (weight-based dosing) and with PEG/RIBA in treatment-naïve subjects with chronic genotype 1 HCV infection. In Part A, thirty (30) subjects with genotype 1 will be randomized to 75 mg GS-9256 BID plus 40 mg GS-9190 BID or 75 mg GS-9256 BID plus 40 mg GS-9190 BID plus RIBA 1000-1200 mg/day for 28 days. In Part B, an additional fifteen (15) subjects with genotype 1 will receive 75 mg GS-9256 BID plus 40 mg GS-9190 BID in combination with PEG/RIBA for 28 days. After the 28-day treatment period, subjects will receive PEG/RIBA as standard of care (SOC).
In Part A, for any subjects meeting pre-defined, individual, virologic criteria, PEG/RIBA standard of care will be started prior to Day 28.
Both PEG and RIBA will be administered at their currently approved dosages for treatment of HCV infection in accordance with appropriate labeling. Subjects will be monitored for safety (including ECG monitoring), antiviral activity, pharmacokinetics, and resistance 2-3 times weekly through Day 28.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GS-9256, GS-9190 and Ribavirin in people with HCV Infection, run by Gilead Sciences at 12 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 15 inclusion and 27 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 May 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites in Germany, France, Belgium, United Kingdom. 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 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?
Percentage of subjects achieving rapid virologic response (RVR) (time frame: Day 28). 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?
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 May 2012.
