Inclusion criteria

1. Healthy male trial participant 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 2. Age of 18 to 55 years (inclusive) 3. Body mass idnex (BMI) of 18.5 to 29.9 kg/m2 (inclusive) 4. Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial Further inclusion criteria apply

Exclusion criteria

1. Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator 2. Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 bpm 3. Any laboratory value outside the reference range that the investigator considers to be of clinical relevance 4. Any evidence of a concomitant disease assessed as clinically relevant by the investigator Further
