About this study

Official title: Effect of Triple Direct Acting Antiviral Agents (DAAs) for Non-cirrhotic Subjects With Chronic HCV G1b Infection

Being tested
LDV/SOF+ASV, SOF+DCV+SMV, SOF+DCV+ASV

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of participants with sustained virologic response 12 weeks after discontinuation of therapy (SVR12)

    SVR12 is defined as HCV RNA < lower limit of quantification (LLOQ) 12 weeks after last dose of study drug.

    Measured: Post treatment Week 12

  2. Proportion of participants with adverse events leading to permanent discontinuation of study drug(s)

    Measured: Baseline up to Week 24

Secondary outcomes (3)
  1. Proportion of participants with unquantifiable HCV viral load at specified time points during and after treatment.

    Measured: Baseline up to Week 24

  2. HCV RNA levels and change during and after treatment.

    Measured: Baseline up to Week 24

  3. Proportion of participants with on-treatment virologic breakthrough and relapse

    Viral breakthrough is defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) during treatment, but did not achieve a sustained virologic response (SVR). Viral relapse is defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) within 4 weeks of end of treatment, but did not achieve an SVR.

    Measured: Baseline up to Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LDV/SOF+ASV, SOF+DCV+SMV and SOF+DCV+ASV in people with Chronic Hepatitis C Infection, run by Humanity and Health Research Centre at 1 site in China.

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 7 inclusion and 6 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 Mar 2016. 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 China. 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?

Proportion of participants with sustained virologic response 12 weeks after discontinuation of therapy (SVR12) (time frame: Post treatment 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 NCT02470858, 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 Mar 2016; AzTrials last refreshed its copy on 7 Nov 2026.
