Clinical Drug Trial in Healthy Male Subjects to Determine and Compare the Blood Concentrations of BI 144807 Following Administration as Oral Solution and Tablet Under Fasted and Fed Conditions

An Open-label, Single Dose, Randomised, Crossover Trial in Healthy Male Subjects to Investigate the Relative Bioavailability of Tablet and Oral Solution of Two Doses of BI 144807 and Relative Bioavailability of BI 144807 When Administered as Tablet Under Fed and Fasted Conditions

The purpose of this trial is to investigate the relative bioavailability of a BI 144807 tablet formulation compared to the oral solution formulation after single dose administration (intermediate and high dose) under fasted conditions. Further objectives are to assess whether and to what extent food affects single dose pharmacokinetics of BI 144807 administered as tablet, and to compare the relative bioavailability of two different tablet formulations.
