Primary Outcome Measures
NameTimeMethod
The Percentage of Subjects With Drug-related Adverse EventsFrom baseline up to the start of follow-up period (from Day 1 to Day 35)

The percentage of subjects with possibly drug-related AEs (as defined by the investigator) during the treatment period.

Reversal of Dabigatran-induced Prolongation of Blood Coagulation TimeEnd of last infusion and 10 minutes after completion of last infusion of BI 655075

Percentage of subjects with at least one assay value from diluted thrombin time (dTT) or ecarin clotting time (ECT) reversed within 10min after completion of infusion. Reversal was defined as return to baseline, where the threshold for reversal to baseline was determined using PK/PD correlation between unbound sum dabigatran and the clotting parameters ECT and dTT. Measured at the end of the infusion and 10 min later.
