About this study

Official title: A Study to Evaluate the Effects of Two Different Meal Types, Omeprazole and Ranitidine on Danoprevir Pharmacokinetics When Coadministered With Ritonavir in Healthy Subjects

This randomized, open-label study will evaluate the effect of food, and the effect of omeprazole and ranitidine on danoprevir co-administered with ritonavir. Volunteers will be assigned to one of two treatment groups. Volunteers in both groups will receive oral doses of danoprevir and ritonavir. In addition, volunteers in group 2 will receive oral doses of omeprazole and ranitidine. The anticipated time of the study is approximately 6 weeks.

Being tested
danoprevir, omeprazole, ranitidine, ritonavir

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing danoprevir, omeprazole and ranitidine 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 3 inclusion and 11 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?

Effect of omeprazole on the area under the plasma concentration time curve of danoprevir when co-administered with ritonavir (time frame: 1 day). The study lists 3 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.
