Brief Summary

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.

Eligibility Criteria

Inclusion Criteria

Healthy subjects and F4 liver cirrhosis patients:

• Signed and dated written informed consent in accordance with the International Conference on Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial
• Either male subject, or female subject who meets any of the following criteria for a highly effective contraception from at least 30 days before the first administration of trial medication until 30 days after trial completion:

• Use of combined (estrogen and progestogen containing) hormonal contraception that prevents ovulation (oral, intravaginal, or transdermal), plus condom
• Use of progestogen-only hormonal contraception that inhibits ovulation (only injectables or implants), plus condom
• Use of intrauterine device (IUD) or intrauterine hormone-releasing system (IUS)
• Sexually abstinent
• A vasectomised sexual partner who received medical assessment of the surgical success (documented absence of sperm) and provided that the partner is the sole sexual partner of the trial participant
• Surgically sterilised (including hysterectomy)
• Postmenopausal, defined as no menses for 1 year without an alternative medical cause (in questionable cases a blood sample with levels of follicle-stimulating hormone (FSH) above 40 units per liter (U/L) and estradiol below 30 nanograms per liter (ng/L) is confirmatory)
• Not taking any components in the cocktail within 4 weeks of enrolment (except from caffeine: methylxanthine-containing drinks or foods such as coffee, tea, cola, energy drinks, or chocolate are not allowed within 48 hours (h) before and during the inhouse confinement at the trial site)

Healthy subjects only:

• Healthy male or female subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs (blood pressure (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests
• Age of 18 to 75 years (inclusive)
• Body mass index (BMI) of 18.5 to 35 kilograms per meter squared (kg/m2) (inclusive). A BMI of ≥ 30 is no exclusion criterion when the subject can be considered healthy apart from the elevated BMI

F4 liver cirrhosis patients only

• Male and female subjects, 18 to 75 years
• BMI of 18.5 to 40.0 kg/m2 (inclusive)
• Stable treatment for at least 4 weeks prior to taking the cocktail. Furthermore, patients can only be included into the trial a) if they are in constant specialist care at the timepoint of enrollment into the study and b) if they are willing to continue to be in specialist care after participation in the 0352.2190 study

Exclusion Criteria

Healthy subjects and F4 liver cirrhosis patients:

• Subjects already taking any components in the cocktail within 4 weeks before cocktail administration (except from caffeine: methylxanthine-containing drinks or foods such as coffee, tea, cola, energy drinks, or chocolate are not allowed within 48 h before and during the in-house confinement at the trial site)
• Subjects with any other condition that would preclude administration of caffeine, warfarin, omeprazole, metoprolol, and midazolam (i.e., contraindicated as per Summary of Product Characteristics (SmPC)), such as hypersensitivity to active ingredient or any of the excipients or to any beta receptor blockers
• Repeated measurement of systolic blood pressure outside the range of 90 to 150 millimeter of mercury (mmHg), diastolic blood pressure outside the range of 50 to 95 mmHg, or pulse rate outside the range of 50 to 90 beats per minute (bpm)
• Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)
• Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
• History of relevant orthostatic hypotension, fainting spells, or blackouts
• Relevant (other than Hepatitis B virus (HBV) or Hepatitis C virus (HCV)) chronic or acute infections (including an ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection)
• Patients receiving antiviral therapy at the time of inclusion into the trial
