Who may be able to join

About this study

The objective of this study is to determine the effect of multiple dose omeprazole on the pharmacokinetics of boceprevir and vice versa.

Furthermore, the safety of steady state boceprevir combined with multiple dose omeprazole will be evaluated.

Read the detailed description

It is known that some drugs can significantly influence the bioavailability of other drugs. For example the proton pump inhibitors decrease the absorption of some protease inhibitors used in HIV treatment or of some oral tyrosine kinase inhibitors used in oncology. Proton pump inhibitors increase the pH in the stomach and might therefore decrease the solubility of other drugs with decreased absorption as a consequence.

Boceprevir (BOC) is an Hepatitis C (HCV) NS3 serine protease inhibitor that has recently received FDA approval for the treatment of chronic HCV infection. The drug substance is slightly soluble in water and administration with food increases the oral bioavailability of BOC relative to the fasted state, by 40% to 60% based on AUC.

Omeprazole (OME) is the most frequently used proton pump inhibitor. It is the second most prescribed drug in The Netherlands, with 5 million prescriptions a year.

OME is metabolized by CYP2C19 and CYP3A4 and is known to induce CYP1A2 and inhibit CYP2C19. BOC is a potent inhibitor of CYP3A4/5 and is not metabolised by CYP1A2 or CYP2C19. No interaction on metabolism of BOC is expected. However, an increase of OME levels may be expected due to the inhibition of CYP3A4 by BOC.

As proton pump inhibitors are widely used it is relevant to know if a drug-drug interaction between proton pump inhibitors and BOC exists which might influence the bioavailability of BOC.

This study is designed to determine the effect of multiple dose omeprazole on the pharmacokinetics of boceprevir and vice versa.

Furthermore, the safety of steady state boceprevir combined with multiple dose omeprazole will be evaluated.

What is being measured

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

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing boceprevir and Omeprazole in people with HCV Infections and Gastric Acid-related Disorders, run by Radboud University Medical Center at 1 site in Netherlands.

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 12 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 Dec 2020. 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 Netherlands. 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?

boceprevir concentrations (time frame: AUC: pre-dose, 0.5, 1. 1.5, 2, 2.5, 3, 4, 5, 6 and 8h). 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 NCT01470690, 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 Dec 2020.
