About this study

Official title: Profiling Study for the Hepatic Cytochrome P450 (CYP) Isozymes CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A in Healthy Subjects and in Patients With Stage 4 (F4) Liver Fibrosis / Cirrhosis by the Combined Administration of the Probe Substrates (the Cocktail) Caffeine, Warfarin, Omeprazole, Metoprolol, and Midazolam

This study is open to healthy adults and adults with liver cirrhosis. The purpose of this study is to compare how different medicines are handled by the body in people with and without liver cirrhosis. The study measures if the approved medicines caffeine, warfarin,omeprazole, metoprolol, and midazolam are processed differently in people with liver cirrhosis than in people without liver cirrhosis. This study will help to understand how new medicines being developed are handled by the body in people with liver cirrhosis.

There are 3 groups in this study: people without liver cirrhosis, people with mild liver cirrhosis, and people with moderate liver cirrhosis. All participants get 1 dose each of caffeine, warfarin, omeprazole, metoprolol, and midazolam by mouth. The participants with liver cirrhosis continue their regular treatment for the condition during the study.

Participants are in the study for about 1 month. During this time, they visit the study site 5 times. For 1 of the visits, participants stay overnight for 2 nights at the study site. To assess the main study endpoint, the doctors take frequent blood samples from the participants. The doctors also regularly check participants' health and take note of any unwanted effects.

Individual data sharing
No: Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g., studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

Questions about this trial

What is this clinical trial studying?

A study testing Caffeine, Warfarin sodium and Omeprazole in people with Liver Cirrhosis, run by Boehringer Ingelheim at 1 site in Germany.

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 21 inclusion and 10 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 10 Sep 2025. 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 Germany. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Area Under the Concentration Time Curve of Caffeine, Omeprazole and Metoprolol in Plasma Over the Time Interval From 0 to 24 Hours (AUC0-24) (time frame: 2 hours before drug administration and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 48-72 and 96 (+/-12) hours after drug administration.). The study lists 5 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 10 Sep 2025.
