Eligibility Criteria
-----------------
Inclusion Criteria: Healthy male 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 65 years (inclusive) Body Mass Index (BMI) of 18.5 to 29.9 kg/m2 (inclusive) Signed and dated written informed consent prior to admission to the study, in accordance with Good Clinical Practice (GCP) and local legislation Further inclusion criteria apply Exclusion Criteria: Any finding in the medical examination (including Blood Pressure (BP), Pulse Rate (PR) or Electrocardiogram (ECG)) deviating from normal and assessed as clinically relevant by the investigator Repeated measurement of systolic blood pressure outside the range of 90 to 139 mmHg, diastolic blood pressure outside the range of 45 to 89 mmHg, or pulse rate outside the range of 40 to 100 bpm Any laboratory value outside the reference range that the investigator considers to be of clinical relevance Any evidence of a concomitant disease assessed as clinically relevant by the investigator Clinically significant gastrointestinal (including known or suspected inflammatory bowel disease), hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders Further exclusion criteria apply

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Concentration-time Curve of BI 730357 Over the Time Interval From 0 to Infinity (Dose Normalized). | Area under the concentration-time curve of the analyte over the time interval from 0 to infinity (AUC0-∞). For both arms results are presented in millimole (mmol) * hours (h) / Litre (L) / kilogram (kg). This was achieved by transforming the reference arm to the treatment arm and normalizing the results according to the respective dose. | Test treatment T: within 3h before and 1,1.5,2,2.5,3.5,5,7,12,24,72,120,168h after oral administration. Reference treatment R: within 3h before and 5,10,15,30,45 minutes and 1.25,2.25,3.75,5.75,10.75,22.75,70.75,118.75,166.75h after start of iv infusion. |
