* 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)

* Blood donation of more than 100 mL within 30 days prior to the administration of trial medication or intended donation during the trial
* Intention to perform excessive physical activities within one week prior to the 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 in males) 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 subject with women of child bearing potential (WOCBP) partner who is 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
* Subjects who, in the investigator's judgement, are perceived as having an increased risk of bleeding, e.g. history of haemorrhagic disorders, clinical relevant petechial bleeding, occult blood in faeces, haematuria in repeated urine tests, trauma or surgery within the last month planned surgery during trial participation, history of arteriovenous malformation or aneurysm, history of gastroduodenal ulcer disease or gastrointestinal haemorrhage, history of intracranial, intraocular, spinal, retroperitoneal, or atraumatic intraarticular bleeding, use of drugs that may interfere with haemostasis during trial conduct (e.g. acetylic salicylic acid or other non-steroidal anti-inflammatory drugs)
* Repeated platelet counts below 100 cells/nL at screening
* Bleeding times (to monitor platelet function) above reference range at screening
* Repeated absolute B cell (CD19+) counts below 40/μL at screening
* Serum potassium below normal range at screening
* A history or current clinical signs of acute pancreatitis
* Further exclusion criteria apply.
