Healthy Volunteers

Inclusion Criteria

- Participants who are overtly healthy according to complete medical history, including the physical examination, vital signs (blood pressure, pulse rate), 12-Lead electrocardiogram (ECG), and clinical laboratory tests
- Race: Chinese
- Age: 18 to 45 years (inclusive) of age
- Weight: Body mass index (BMI): ≥ 18.0 and <= 27.9 kg/m²
- Male participants
- Subjects who agree to use adequate contraception when sexually active during the study period and for 90 days after receiving the investigational medicinal product and not to act as sperm donor for 90 days after dosing.

Exclusion Criteria

Medical and Surgical History
- Any findings from the medical examination (including medical history, physical examination, vital signs, laboratory tests and ECG) deviating from normal and deemed by the investigator to be of clinical relevance
- Medical history of hypogeusia/dysgeusia or dysfunction in the ability to taste
- Any known presence or history of severe allergies, non-allergic drug reactions, or multiple drug allergies
- Known or suspected malignant tumors or carcinoma in situ
- Known liver disease: existing acute or chronic progressive liver disease, e.g. disturbance of bilirubin excretion (Dubin–Johnson and Rotor syndromes); disturbances of bile secretion and flow (cholestasis); presence or history of liver tumors (benign or malignant). (Note: According to this criterion, there must have been an interval of at least 6 months between the subsidence of any viral hepatitis [normalization of liver parameters] and the screening visit.)
- Any known relevant kidney disease (e.g. glomerulonephritis) or any renal injury associated with multisystem diseases/disorders (e.g. systemic lupus erythematosus, diabetic nephropathy)
- Known metabolic disorders (e.g. diabetes mellitus, severe hypertriglyceridemia)
- Known cardiovascular disorders requiring treatment
- Migraine with neurological symptoms (complicated migraine)
- Incompletely cured pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal
- Known hypersensitivity to the study interventions including components of the preparation
Medication, drug use and special behavioral patterns
- Regular use of therapeutic or recreational drugs, e.g. carnitine products, anabolics, high-dose vitamins
- Intake of drugs with a long half-life (>24 hours) within a timeframe of less than 5 half-lives before study drug administration
- Use of any systemic or topically active drug(s) that might influence the results of the study within the 14 days before study intervention administration or during the study until follow-up. (Note: This includes drugs that might affect the PK of BAY 1817080, e.g. laxatives, loperamide, metoclopramide, antacids, H2-receptor antagonists, cytochrome P450 [CYP] 3A4 inducers, strong CYP3A4 inhibitors).
Electrocardiogram, blood pressure, pulse rate
- Clinically relevant ECG findings, such as a second- or third-degree atrioventricular block, prolongation of the QRS complex over 120 msec at screening or pre-dose baseline measurement on Day -1
 Physical examination
- Clinically relevant findings in the physical examination
Neurological examination
- Clinically relevant findings in the orientating, basic neurological examination
Laboratory examination
- Positive result in urine drug screening, or positive alcohol breath test
Other
- Participation in another study and received an investigational drug within the 2 months or a longer and more appropriate time as determined by the investigator (e.g. approx. 5 half-lives of the previous investigational drug) before first study intervention administration
- Criteria that in the opinion of the investigator preclude participation for scientific reasons, for reasons of compliance, or for reasons of the participant’s safety
