A Study to Compare How Different Medicines (Rosuvastatin, Digoxin, Metformin, and Furosemide) Are Handled by the Body of Healthy People and People With Liver Cirrhosis

Inclusion criteria

Healthy subjects and F4 liver cirrhosis patients:

• Signed and dated written informed consent in accordance with the International Conference on Harmonization-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 vasectomized 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 sterilized (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

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

• further inclusion criteria apply

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

• further inclusion criteria apply

Healthy subjects and F4 liver cirrhosis patients:

• Subjects already taking digoxin, furosemide, metformin or rosuvastatin within 4 weeks of enrolment into the study. Furthermore, patients taking ezetimibe, fibrates, or the maximal dose (per Summary of Product Characteristics (SmPC)) of any statin are excluded from this study.

• Subjects with any other condition that would preclude administration of digoxin, furosemide, metformin or rosuvastatin (i.e., contraindicated as per SmPC), such as hypersensitivity to active ingredient or any of the excipients or to sulphonamides, hypovolemia or dehydration, and partial obstructions of urinary outflow (e.g., prostatic hypertrophy)

• 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 60 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

• 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 vasectomized 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

 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)
