Clinical Trial Summary

Researchers are looking for a better way to treat people with chronic kidney diseases. Before a treatment can be approved for patients to take, researchers do clinical studies to better understand its safety and what happens to the drug in the body.

In this study researchers will investigate how the liver function influences blood concentrations of runcaciguat in participants with different degrees of liver impairment compared to participants with normal liver function.

The participants will all take one tablet with 15 mg runcaciguat by mouth. Prior to inclusion into the study, all participants will have a screening examination within 21 to 2 days prior to dosing to check eligibility for study participation.

During the study, all of the participants will stay at the study site for up to 8 days (from Day -1 to Day 7), whereby Day 6 and 7 might also be performed in an ambulatory setting. Blood and urine samples will be collected. The physician will check the participants' heart health using an electrocardiogram (ECG) and by measuring blood pressure and heart rate. The participants will answer questions about their wellbeing and taken medications.

The participants will have a follow-up examination 7 to 11 days after dosing to follow-up their health.

Each participant will be in the study for approximately 5 weeks. The entire study will last about 9 months.

• Participation in another clinical trial within 3 months (for previous multi-dose study) or 1 month (for previous single dose study) before dosing.

• Exclusion periods from other studies or simultaneous participation in other clinical studies.

coronavirus disease 2019 (COVID-19) specific exclusion criteria

• Positive SARS-CoV-2 viral polymerase chain reaction (PCR) test

Main exclusion Criteria for participants with hepatic impairment Medical and surgical history

• Pre-existing diseases beside hepatic impairment for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal.

• Evidence of hepatic encephalopathy related to chronic liver disease > grade 2 (exclusion by Number Connection Test).

• Congestive heart failure of New York Heart Association grade III or IV.

• Systolic blood pressure below 100 mmHg or above 169 mmHg.

• Diastolic blood pressure below 50 and above 95 mmHg.

• Resting heart rate below 50 beats per minute (bpm) or above 95 bpm. Laboratory examination

• Platelet count < 40 x 10^9/L.

• Hemoglobin <9 g/dL.

• Alkaline phosphatase (AP) = 4 times the upper limit of normal (ULN).

Main Exclusion criteria for control group of participants Medical and surgical history

• A history of relevant diseases of vital organs, the central nervous system, or other organs.
