A Study in Healthy Volunteers Investigating How Quickly and to What Extent BAY1817080 is Taken up, Distributed, Broken Down and Eliminated From the Body, as Well as the Difference Between 2 Different Types of Tablets of BAY1817080 and the Difference Between Oral Dose and Dose in the Vein

Study Overview
=================
Brief Summary
-----------------
The main purpose of this study is to investigate how quickly and to what extent BAY1817080 is absorbed (taken up), distributed, metabolized (broken down) and eliminated from the body (this is called pharmacokinetics). The pharmacokinetics of BAY1817080 administered as tablets will be compared to the pharmacokinetics of BAY1817080 administered as intravenous (iv; in the vein) infusion (this is called absolute bioavailability). Furthermore, 2 different types of tablets with BAY1817080 (Formulation A and Formulation B) will be compared with regard to pharmacokinetics (this is called relative bioavailability). The effect of a meal on the pharmacokinetics of BAY1817080 administered as tablets will be investigated as well. Finally, it will also be investigated how safe BAY1817080 is and how well BAY1817080 is tolerated.

| Experimental: Group 2 - BAY1817080 Dose 2<br>Participants will receive a) one single oral dose of BAY1817080 - Formulation A at dose 2 with moderate-fat, moderate-calorie meal (MF, MC); b) one single oral dose of BAY1817080 - Formulation B at dose 2 along with one intravenous (i.v.) infusion of 0.1 mg [13C715N]-BAY1817080; and c) one single oral dose of BAY1817080 - Formulation B at dose 2 with high-fat, high-calorie meal (HF, HC). The 3 treatments will be administered with a randomized sequence | Drug: BAY1817080 - Formulation A<br>* Formulation A<br>Drug: BAY1817080 - Formulation B<br>* Formulation B<br>Drug: [13C715N]-BAY 181708 stable isotope label (SIL)<br>* 0.1 mg [13C715N]-BAY181708, 15 minutes i.v. infusion at the estimated tmax after administration of Formulation B<br>|

| Effect of a high-fat, high-calorie meal (HF,HC) on the PK of BAY1817080 after a single oral dose of Formulation B at two doses in comparison to the fasted state evaluated by AUC | Area under the concentration versus time curve from zero to infinity after single dose administration (AUC) of BAY1817080 will be analyzed assuming log-normally distributed data. AUC from time 0 to the last data point greater than lower limit of quantification (AUC[0-tlast]) will be used if AUC cannot be calculated reliably in all subjects. | Up to 10 days |
