What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under Curve From 0 to 6 Hours at Steady State (AUC0-6,ss) | AUC0-6,ss represents the area under the concentration curve of olodaterol in plasma from 0 to time t=6 hours at steady state, where t is defined as the latest time-point where at least 2/3 of the subjects in both treatment periods reveal quantifiable plasma concentrations of olodaterol. The geometric mean is actually the adjusted geometric mean. The geometric coefficient of variation (gCV) is the intra-individual gCV. | Day 8 of period 1 and day 14 of period 2 | 
| Maximum Concentration at Steady State (Cmax,ss) | Cmax,ss represents the maximum concentration of olodaterol and olodaterol glucuronide (a metabolite of olodaterol) in plasma at steady state. The geometric mean is actually the adjusted geometric mean. The geometric coefficient of variation (gCV) is the intra-individual gCV. | Day 8 of period 1 and day 14 of period 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time From Dosing to the Maximum Concentration at Steady State (Tmax,ss) | tmax,ss represents the time from dosing to maximum concentration of olodaterol and olodaterol glucuronide in plasma at steady state. | Day 8 of period 1 and day 14 of period 2 | 
| Fraction of Urine Excretion From 0 to 24 Hours at Steady State (fe0-24,ss) | fe0-24,ss represents the fraction of olodaterol eliminated in urine from time point 0 to 24 hours after administration at steady state. | Day 8 of period 1 and day 14 of period 2 | 
| Amount of the Analyte Excreted in Urine From 0 to 24 Hours at Steady State (Ae0-24,ss) | Ae0-24,ss represents the amount of olodaterol and olodaterol glucuronide excreted in urine from 0 to time t=24 at steady state. The geometric mean is actually the adjusted geometric mean. The geometric coefficient of variation (gCV) is the intra-individual gCV. | Day 8 of period 1 and day 14 of period 2 | 
| Area Under Curve From 0 to 12 Hours at Steady State (AUC0-12,ss) | AUC0-12,ss represents the area under the concentration curve of olodaterol glucuronide in plasma from 0 to time t=12 at steady state, where t is defined as the latest timepoint where at least 2/3 of the subjects in both treatment periods reveal quantifiable plasma concentrations of the analyte. The geometric mean is actually the adjusted geometric mean. The geometric coefficient of variation (gCV) is the intra-individual gCV. | Day 8 of period 1 and day 14 of period 2 | 
| Clinical Relevant Abnormalities for Vital Signs, Blood Chemistry, Haematology, Urinalysis and ECG | Clinical relevant abnormalities for Vital Signs, Blood Chemistry, Haematology, Urinalysis and ECG. New abnormal findings or worsening of baseline conditions were reported as Adverse Events. | First administration of trial medication until 6 days after last administration of trial medication | 
| Assessment of Tolerability by the Investigator | The investigator assessed tolerability based on adverse events and the laboratory evaluation at the end-of-trial examination. The investigator classified the overall tolerability according to the categories 'good', 'satisfactory', 'not satisfactory', and 'bad'. | End of period 1 and end of period 2 |
