A Study in Healthy Japanese Men to Test How Well Different Doses of BI 764198 Are Tolerated

Study Overview
=================
Brief Summary
-----------------
The main objectives of this trial are to investigate safety and tolerability of BI 764198 in healthy male subjects following oral administration of single dose and multiple rising doses per day over 14 days. Secondary objectives are the exploration of pharmacokinetics (PK) of BI 764198 after single and multiple oral dosing.

Eligibility Criteria
-----------------
Inclusion Criteria: 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 Japanese ethnicity, according to the following criteria: born in Japan, have lived outside of Japan <10 years, and have parents and grandparents who are Japanese Age of 20 to 45 years at screening (inclusive) BMI of 18.5 to 25.0 kg/m2 (inclusive) Signed and dated written informed consent prior to admission to the trial, in accordance with GCP and local legislation Willingness to comply with contraception requirements. Subjects who are sexually active must use adequate contraception methods throughout the trial and until three months after the last administration of trial medication. Adequate methods are: A vasectomy performed at least 1 year prior to screening and with medical assessment of the surgical success or Surgical sterilisation, including bilateral tubal occlusion, hysterectomy or bilateral oophorectomy, of the subject's female partner or The use of condoms, if the female partner uses an adequate contraception method in addition, e.g., intrauterine device (IUD), or hormonal contraception, such as implants and injectables*, combined with oral or vaginal contraceptives, that started at least 2 months prior to first drug administration, or barrier method, e.g., diaphragm with spermicide* * hormonal contraception via implants and injectables, and diaphragm with spermicide are not approved in Japan Unprotected sexual intercourse with a pregnant partner is not allowed throughout the trial and until three months after the last administration of trial medication. Exclusion Criteria: Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed 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 50 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 assessed as clinically relevant by the investigator Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or 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 Further exclusion criteria apply.
