Eligibility criteria:

        Inclusion criteria:

          -  Healthy male subjects according to the investigators assessment, based on a complete
             medical history including a physical examination, vital signs (BP, PR), 12-lead ECG,
             and clinical laboratory tests

          -  Age of 18 to 55 years (incl.)

          -  BMI of 18.5 to 29.9 kg/m2 (incl.)

          -  Signed and dated written informed consent prior to admission to the study in
             accordance with GCP and local legislation

          -  Males who are willing to use a medically acceptable method of contraception during the
             study (from start of treatment until end of trial examination). Acceptable methods of
             contraception for use by male volunteers include sexual abstinence, a vasectomy
             performed at least 1 year prior to dosing, and barrier contraception (condom).
             Subjects, who are not vasectomised or sexually abstinent have to ensure that an
             additional acceptable method of contraception will be used by his female partner such
             as IUD (intrauterine device), surgical sterilisation (including hysterectomy),
             hormonal contraception (e.g. implants, injectables, combined oral or vaginal
             contraceptives) that started at least 2 months prior to first nintedanib
             administration, or barrier method (e.g. diaphragm with spermicide).

        Exclusion criteria:

          -  Any finding in the medical examination (including BP, PR or ECG) is deviating from
             normal and judged as clinically relevant by the investigator

          -  Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg,
             diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the
             range of 45 to 90 bpm

          -  Any laboratory value outside the reference range that the investigator considers to be
             of clinical relevance

          -  Any evidence of a concomitant disease judged as clinically relevant by the
             investigator

          -  Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic,
             immunological or hormonal disorders

          -  Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with
             the pharmacokinetics of the trial medication (except appendectomy and simple hernia
             repair)

          -  Diseases of the central nervous system (including but not limited to any kind of
             seizures or stroke), and other relevant neurological or psychiatric disorders

          -  History of relevant orthostatic hypotension, fainting spells, or blackouts

          -  Chronic or relevant acute infections

          -  History of relevant allergy or hypersensitivity (including allergy to the trial
             medication or its excipients)

          -  Intake of drugs with a long half-life (more than 24 h) within 30 days or less than 10
             half-lives of the respective drug prior to administration of trial medication

          -  Within 10 days prior to administration of trial medication, use of drugs that might
             reasonably influence the results of the trial

          -  Participation in another trial where an investigational drug has been administered
             within 60 days prior to planned administration of trial medication
