What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study drug.
Measured: Posttreatment Week 12
Percentage of Participants Who Discontinued LDV/SOF Drug Due to an Adverse Event (AE)
Measured: 12 weeks
Secondary outcomes (2)
Percentage of Participants With Sustained Virologic Response 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)
SVR4 and SVR24 were defined as HCV RNA < LLOQ 4 and 24 weeks after the last dose of study drug, respectively.
Measured: Posttreatment Weeks 4 and 24
Percentage of Participants With Overall Virologic Failure
Virologic failure was defined as
- On-treatment virologic failure
- confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ, while on treatment (ie, breakthrough),
- confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment (ie, rebound),
- HCV RNA persistently ≥ LLOQ through 8 weeks of treatment (ie, nonresponse)
- Relapse
- HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement
Measured: Up to Posttreatment Week 24

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing LDV/SOF and RBV in people with Hepatitis C Virus Infection, run by Gilead Sciences at 4 sites in Egypt.
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 8 inclusion and 5 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 16 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Egypt. 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 14 Dec 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?
Percentage of Participants With Sustained Virologic Response 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 NCT02487030, which also lists 2 linked publications.
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 16 Nov 2018.
