    Minimum Age: 18
    Maximum Age: 55
    Age Groups: Adult
    Healthy Volunteers: Yes

    Inclusion Criteria:

    1. Healthy male subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs (BP, PR), 12-lead ECG, and clinical laboratory tests
    2. Age of 18 to 55 years (inclusive)
    3. BMI of 18.5 to 32 kg/m2 (inclusive)
    4. Signed and dated written informed consent prior to admission to the study, in accordance with GCP and local legislation
    5. Male subjects who meet any of the following criteria from at least 30 days before the first administration of trial medication until 30 days after trial completion:

    * Use of adequate contraception, e.g. use of condom (male subjects) plus any of the following methods (female partners): intrauterine device, hormonal contraception (e.g. implants, injectables, combined oral or vaginal contraceptives) that started at least 2 months prior to first drug administration, or barrier method (e.g. diaphragm with spermicide)
    * Sexually abstinent
    * Vasectomised (vasectomy at least 1 year prior to enrolment)
    * Surgically sterilised female partner (including hysterectomy, bilateral tubal occlusion or bilateral oophorectomy)
    * Postmenopausal female partner, defined as at least 1 year of spontaneous amenorrhea

    Exclusion Criteria:

    1. Any finding in the medical examination (including ECG) deviating from normal and assessed as clinically relevant by the investigator
    2. Repeated measurement of systolic blood pressure outside the range of 100 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 bpm
    3. Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
    4. Any evidence of a concomitant disease assessed as clinically relevant by the investigator
    5. Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
    6. Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)
