Safety and Pharmacokinetics of Single Rising Doses of BI 705564 and Food Effect on BI 705564 in Healthy Male Subjects

Study Overview
=================
Brief Summary
-----------------
Investigation of safety, tolerability, pharmacokinetics and pharmacodynamics of single rising doses of BI 705564 and of the food effect on BI 705564 in healthy male subjects

Detailed Description
-----------------
The primary objective of the single rising dose part under fasting and under fed conditions is to investigate safety and tolerability of BI 705564 in healthy male subjects following oral administration of single rising doses. Secondary objectives are the exploration of pharmacokinetics (PK) including dose proportionality, and pharmacodynamics (PD) of BI 705564 after single rising doses. The objective of the food effect part is to explore the relative bioavailability of BI 705564 tablets under fed and fasted conditions following the oral administration of single doses.

QT/ QTc interval prolongation) Participation in another trial where an investigational drug has been administered within 60 days prior to planned administration of trial medication, or current participation in another trial involving administration of investigational drug Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day) Inability to refrain from smoking on specified trial days Alcohol abuse (consumption of more than 30 g per day) Drug abuse or positive drug screening Blood donation of more than 100 mL within 30 days prior to administration of trial medication or intended donation during the trial Intention to perform excessive physical activities within one week prior to administration of trial medication or during the trial Inability to comply with dietary regimen of the trial site A marked baseline prolongation of QT/ QTc interval (such as QTc intervals that are repeatedly greater than 450 ms) or any other relevant Electrocardiogram [ECG] finding at screening A history of additional risk factors for Torsades de Pointes (such as heart failure, hypokalemia, or family history of Long QT Syndrome) Subject is assessed as unsuitable for inclusion by the investigator, for instance, because considered not able to understand and comply with study requirements, or has a condition that would not allow safe participation in the study In addition, the following trial-specific exclusion criteria apply: Male subjects with women of childbearing potential [WOCBP] partner who are unwilling to use male contraception (condom or sexual abstinence) from the first administration of trial medication until 30 days after last administration of trial medication Repeated absolute B cell (CD19+) counts below 40/μL at screening Repeated platelet counts below 100 cells/nL at screening Serum potassium below normal range at screening A history or current clinical signs of acute pancreatitis
