          6. Male subjects who

               -  are documented to be sterile or consistently and correctly use a condom while
                  their female partners (if of childbearing potential) agree to use any of the
                  following adequate contraception methods: implants, injectables, combined oral
                  contraceptives, intrauterine device (IUD) from the date of screening until at
                  least 6 months after the last dose of BI 655064 taken in the current trial.

               -  do not donate any sperm sample for procreation purposes, from the date of
                  screening until at least 6 months after last dose of BI 655064 taken in the
                  current trial.

        It is the responsibility of the male subject to ensure that his partner does not become
        pregnant during all the study duration.

        Exclusion criteria:

          1. Any finding in the medical examination (including Blood pressure, Pulse rate or
             Echocardiogram) deviating from normal and judged clinically relevant by the
             investigator

          2. Any laboratory value outside the reference range that the investigator considers to be
             of clinical relevance

          3. Any evidence of a concomitant disease judged clinically relevant by the investigator

          4. Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic,
             immunological or hormonal disorders

          5. Diseases of the central nervous system (such as epilepsy), other neurological

             reasonably influence the results of the trial

         10. Participation in another trial with investigational drug administration within 60 days

             interval > 450 ms) at screening examination

         19. Positive results of infectious serology (Hepatitis B Surface Antigen, Hepatitis B Core

         22. Subjects who in the investigator's judgement are perceived as having an excessive risk
             of thromboembolism for example because of a personal history and/or a first degree
             relative with a personal history with onset under the age of 55 of significant
             thromboembolism, including but not limited to deep vein thrombosis, pulmonary

             not able to understand and comply with study requirements or has a condition that
             would not allow safe participation in the study
