Safety, Tolerability, Pharmacokinetics of Single Rising Oral Doses of BI 1181181 in Healthy Male Volunteers, Including Investigation of the Effect of Food on the Bioavailability of BI 1181181

Study Overview
=================
Brief Summary
-----------------
To investigate the safety, tolerability, pharmacokinetics (including dose proportionality assessment), and pharmacodynamics of single rising oral doses of BI 1181181 (Single rising dose (SRD) part) Secondly, to investigate the relative bioavailability of the tablet versus the powder for oral solution (PfOS) and the effect of food on the pharmacokinetics of BI 1181181 (Bioavailability/Food effect (BA/FE) part)

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number (%) of subjects with drug-related adverse events (AEs) |  | up to 72 h | 
| AUC0-tz (area under the concentration-time curve of the analyte in plasma over the time interval from 0 to the last quantifiable data point) |  | up to 72 h | 
| Cmax (maximum measured concentration of the analyte in plasma) |  | up to 72 h | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Aet1-t2 (Amount of analyte that is eliminated in urine from the time point t1 to timepoint t2 after single dose administration) |  | up to 72 h | 
| Cmax (maximum measured concentration of the analyte in plasma) |  | up to 72 h | 
| tmax (time from dosing to maximum measured concentration of the analyte in plasma) |  | up to 72 h | 
| AUC0-infinity (area under the concentration-time curve of the analyte in plasma over the time interval from 0 extrapolated to infinity) |  | up to 72 h | 
| t1/2 (terminal half-life of the analyte in plasma) |  | up to 72 h |
