What is being measured
The primary outcome is the main question the study is designed to answer.
Part A: Plasma Pharmacokinetics of SOF, EFV, Tenofovir (TFV), and FTC: AUCtau at Day 7
AUCtau: concentration of drug over time (area under the plasma concentration versus time curve over the dosing interval).
Data for this outcome measure were collected for participants in Part A only.
Measured: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose
Part A: Plasma Pharmacokinetics of SOF, EFV, TFV, and FTC: Cmax at Day 7
Cmax: maximum observed concentration of drug in plasma.
Data for this outcome measure were collected for participants in Part A only.
Measured: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose
Part B: Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After Discontinuation of Therapy (SVR12)
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) at 12 weeks after stopping study treatment.
Data for this outcome measure were collected for participants in Part B only.
Measured: Posttreatment Week 12
Incidence of Adverse Events Leading to Permanent Discontinuation of Study Drug(s)
The percentage of participants discontinuing any study drug due to an adverse event was summarized.
Measured: Up to 12 weeks
Secondary outcomes (2)
Part B: Percentage of Participants With Sustained Virologic Response at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)
SVR4 and SVR24 was defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study drug, respectively.
Data for this outcome measure were collected for participants in Part B only.
Measured: Posttreatment Weeks 4 and 24
Part B: Percentage of Participants Experiencing Viral Breakthrough or Viral Relapse
Viral breakthrough was defined as having confirmed detectable HCV RNA levels (HCV RNA > LLOQ) on treatment after having previously had undetectable HCV RNA levels (HCV RNA < LLOQ) while on treatment.
Viral relapse was defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) at end of treatment, but did not achieve an SVR.
Data for this outcome measure were collected for participants in Part B only.
Measured: Posttreatment Weeks 4 and 24

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing SOF, EFV/FTC/TDF and EFV in people with Hepatitis C and HIV, run by Gilead Sciences at 1 site in Puerto Rico.
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 6 inclusion and 7 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 1 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Puerto Rico. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Yes. Results are posted in the registry (first posted 1 Oct 2014). 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?
Part A: Plasma Pharmacokinetics of SOF, EFV, Tenofovir (TFV), and FTC: AUCtau at Day 7 (time frame: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose). The study lists 4 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 NCT01565889, 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 1 Oct 2014.
