This is an interventional treatment trial for Healthy Read More

Key Inclusion Criteria for all trial participants:

• Age ≥ 18 years at Screening
• Male or female. Women of childbearing potential (WOCBP) participants and male participants able to father a child must be ready and able to use a highly effective method of birth control per ICH M3 (R2) that results in a low failure rate of less than 1% per year when used consistently and correctly throughout the Trial
• Mean Arterial Pressure (MAP) ≥ 85 mmHg at screening visit
• Estimated Glomerular Filtration rate (eGFR) > 70 mL/min/1.73m² according to the CKD-EPI formula at screening visit
• Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial

Key inclusion for Patient Groups 1 and 2

• If on treatment with non-selective beta blockers (NSBB), stable dose since ≥ 8 weeks prior to screening, with no planned dose change of the therapy during study conduct. All other medications stable 4 weeks prior to screening.
• Patient Group 1: Patients with CTP A and portal hypertension (defined as liver stiffness >15 kPa during screening) and without a previous decompensation event [ascites, variceal hemorrhage, encephalopathy, or jaundice (except Gilbert's disease or hemolysis when bilirubin will be almost exclusively indirect hyperbilirubinemia)]. Self-limited and resolved historical events of decompensation like ascites or encephalopathy are allowed if they have occurred at least 6 weeks prior to screening and do not require continued therapeutic intervention at the time of screening.
• Patient Group 2: Patients with CTP B (with liver stiffness >15 kPa during screening)

Key inclusion for Healthy Volunteer group

• Subjects who are healthy, according to the investigator's assessment, individually matched to a participant among Patient Groups 1 and 2 according to the following criteria: age within ± 5 years, body weight within ± 15%, and gender
• Further inclusion criteria apply

Key exclusion for all trial participants

• Ongoing chronic alcohol or drug use, which in the investigator's opinion, makes the patient an unreliable trial participant or unlikely to complete the trial.
• History of relevant orthostatic hypotension, fainting spells, or blackouts based on the investigator´s judgment

Key exclusion for Patient Groups

• Patient Group 2: treatment-refractory ascites
• Patient Group 2: recent decompensation event (refractory ascites, recurrent variceal hemorrhage, recurrent hepatic encephalopathy, spontaneous bacterial peritonitis or hepatorenal syndrome) within 6 weeks of screening
• Further exclusion criteria apply
