About this study

Official title: A Single-center, Single-dose, Randomized, Double-blind, Double-dummy, Placebo-controlled, Positive-controlled, Four-way Crossover Study to Investigate the Effect of Danoprevir With Low Dose Ritonavir (DNV/r) on the QT/QTc Interval in Healthy Subjects

This single-dose, randomized, double-blind, double-dummy, placebo-controlled, positive-controlled four-way crossover study will evaluate the effect of a single dose of danoprevir with low-dose ritonavir on the QC/QTc interval in healthy volunteers. Subjects will be randomly assigned to one of four sequences with treatments of A: therapeutic dose of danoprevir plus ritonavir (DNV/r), B: supratherapeutic dose of DNV/r, C: moxifloxacin and D: placebo, with a washout period of at least 7 days between treatments.

Being tested
danoprevir, danoprevir placebo, moxifloxacin, moxifloxacin placebo, ritonavir

What is being measured

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

  1. Threshold pharmacological effect on cardiac repolarization as detected by changes in the QT/QTc interval following single dose

    Measured: approximately 9 weeks

Secondary outcomes (4)
  1. Pharmacokinetics: Plasma concentrations

    Measured: approximately 9 weeks

  2. Safety: Incidence of adverse events

    Measured: approximately 9 weeks

  3. Cardiac response: Electrocardiogram (ECG)

    Measured: approximately 9 weeks

  4. Correlation between pharmacokinetics (plasma concentrations) and QT/QTc interval changes

    Measured: approximately 9 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing danoprevir, moxifloxacin and ritonavir in people with Healthy Volunteer, run by Hoffmann-La Roche at 1 site in France.

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 4 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 Nov 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 France. 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. Some participants in this study may receive a placebo. 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 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.

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?

Threshold pharmacological effect on cardiac repolarization as detected by changes in the QT/QTc interval following single dose (time frame: approximately 9 weeks). 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 2 Nov 2016.
