About this study
Official title: A Phase 2, Open-Label, Multicenter, Multi-cohort Study to Investigate the Safety and Efficacy of Ledipasvir/Sofosbuvir Fixed Dose Combination +/- Ribavirin in Adolescents and Children With Chronic HCV-Infection
The primary objective of the PK Lead-in Phase of the study is to evaluate the steady state pharmacokinetics (PK) and confirm the dose of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) in hepatitis C virus (HCV)-infected pediatric participants. The PK Lead-in Phase will also evaluate the safety, tolerability, and antiviral activity of 10 days of dosing of LDV/SOF FDC in HCV-infected pediatric participants.
The Treatment Phase will be initiated by age cohort after confirmation of age-appropriate LDV/SOF FDC dosage levels. Participants from the PK Lead-in Phase will immediately rollover into the Treatment Phase with no interruption of study drug administration. The primary objective of the Treatment Phase is to evaluate the antiviral efficacy, safety, and tolerability of LDV/SOF FDC +/- ribavirin (RBV) for 12 or 24 weeks in pediatric participants with HCV.
During screening, participants will receive placebo to match LDV/SOF FDC to assess ability to swallow tablets.

Acceptability of LDV/SOF Tablets as Measured by the Percentage of Participants Able/Unable to Swallow Placebo Tablet at Day 1
Participants who were able/unable to swallow placebo tablets were assessed. Participants 12 to < 18 years old were first asked to perform the swallowability assessment using the 90/400 mg placebo tablet. If they were unable to swallow this, they were then asked to perform the swallowability assessment with 22.5/100 mg placebo tablets. Participants 6 to < 12 years old were to be assessed with the 22.5/100 mg placebo tablets. However, 8 participants were mistakenly assessed using the 90/400 mg placebo tablet.
Measured: Day 1
Acceptability of LDV/SOF Granules as Measured by Palatability at Day 1
Participants who were dosed with granules were asked if they tasted the study drug. If they tasted it, then they were asked to provide a number from 0 to 100 to rate the taste of the study drug, with higher scores indicating better taste. Data was then summarized as percentage of participants choosing the following palatability categories: 1) Did not taste the study drug, 2) Tasted drug with score > 60 to 100, 3) Tasted drug with score 40 to 60, and 4) Tasted drug with score of 0 to < 40.
Measured: Day 1

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of the PK Lead-in Phase of the study is to evaluate the steady state pharmacokinetics (PK) and confirm the dose of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) in hepatitis C virus (HCV)-infected pediatric participants. The PK Lead-in Phase will also evaluate the safety, tolerability, and antiviral activity of 10 days of dosing of LDV/SOF FDC in HCV-infected pediatric participants.
The Treatment Phase will be initiated by age cohort after confirmation of age-appropriate LDV/SOF FDC dosage levels. Participants from the PK Lead-in Phase will immediately rollover into the Treatment Phase with no interruption of study drug administration. The primary objective of the Treatment Phase is to evaluate the antiviral efficacy, safety, and tolerability of LDV/SOF FDC +/- ribavirin (RBV) for 12 or 24 weeks in pediatric participants with HCV.
During screening, participants will receive placebo to match LDV/SOF FDC to assess ability to swallow tablets.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing LDV/SOF and RBV in people with Hepatitis C Virus Infection, run by Gilead Sciences at 31 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 3 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 2 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 31 sites in United States, United Kingdom, Australia, 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?
Yes. Results are posted in the registry (first posted 24 Apr 2019). 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?
For Participants in the PK Lead-in Phase, Pharmacokinetic (PK) Parameter: AUCtau of GS-331007 (Metabolite of SOF), LDV, and SOF (time frame: Cohorts 1 and 2 (6 to < 18 years of age): predose, 0.5, 1, 2, 3, 4, 5, 8, and 12 hours postdose on Day 10; Cohort 3 (3 to < 6 years of age): predose, 0.5, 2, 4, 8, and 12 hours postdose on Day 10). 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 NCT02249182, which also lists 10 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 2 Mar 2020.
