About this study
Official title: A Study to Evaluate the Potential Drug-Drug Interaction Between Danoprevir When Coadministered With Low-Dose Ritonavir and Tenofovir Disoproxil Fumarate or Atazanavir in Healthy Adult Volunteers
This randomized, open-label, multiple-treatment multiple-dose, 2-period, 2-sequence study will evaluate potential drug-drug interactions between danoprevir (DNV) when coadministered with low-dose ritonavir (r) and tenofovir disoproxil fumarate (TDF) or atazanavir (ATZ) in healthy volunteers. Subjects will be randomized to receive in Period 1 either single oral doses of TDF and multiple oral doses of DNV/r or multiple oral doses of ATZ/r. In Period 2, all subjects will receive multiple oral doses of DNV/r plus ATZ. Anticipated time on study treatment is up to 20 days.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing atazanavir, danoprevir and ritonavir in people with Healthy Volunteer, run by Hoffmann-La Roche at 1 site in United States.
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 9 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 United States. 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 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?
Pharmacokinetics of tenofovir disoproxil fumarate and atazanavir when coadministered with danoprevir/ritonavir: Area under the concentration-time curve (AUC) (time frame: Pre-dose, and up to 48 hours post-dose Days 1, 8, 11, 16, 20). 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?
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; AzTrials last refreshed its copy on 7 Nov 2026.
