Study to Test the Safety of Increasing Multiple Doses of BAY2328065 Given by Mouth, How the Drug is Tolerated and Acts in the Human Body of Healthy Male Participants. Alteration of the Study Drug Effects by Another Drug and the Availability of the Drug Given in Different Formulations is Also Tested.

Study Overview
=================
Brief Summary
-----------------
Study on the safety and tolerability of a new drug BAY2328065 when given increased doses as tablet or solution over 12 days to healthy male participants. Researcher want to study how the body absorbs, breaks down and excrete the new drug, also when given together with a test meal. In addition the study will investigate changes that take place in the body when BAY2328065 is given together with another drug.

Design Details

Primary Purpose: Basic Science
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The study will be performed in 2 study parts. Each participant will take part in one study part only. Bridging part: This will be a single-center, randomized, open-label cross-over part with 3 study interventions, 3 intervention periods and 2 intervention sequences. Multiple dose escalation part: This will be a single-center, randomized, placebo-controlled, double-blind, parallel group multiple dose escalation part.
Masking: Quadruple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Bridging part: intervention sequence ABC or BAC<br>10 healthy male participants will be randomly allocated to this arm. The study interventions will follow the sequence ABC or BAC: A: single dose of 50 mg BAY2328065 given as LSF in fasted state B: single dose of 50 mg BAY2328065 given as tablet in fasted state C: single dose of 50 mg BAY2328065 given as tablet in fed state (i.e. after a high caloric and high fat meal) | Drug: BAY2328065 LSF<br>* 20 mg/mL LSF (liquid service formulation), orally<br>Drug: BAY2328065 tablet<br>* 50 mg tablet, orally<br>|
| Experimental: Multiple dose escalation part: dose 1<br>10 participants will be randomly allocated to active drug or placebo (8 active drug, 2 placebo). The study intervention will be administered with a single dose on the first dosing day followed by twice daily doses for 10 days followed by a single dose on the last dosing day | Drug: BAY2328065 LSF<br>* 20 mg/mL LSF (liquid service formulation), orally<br>Drug: Placebo LSF<br>* Matching Placebo LSF, orally<br>|
| Experimental: Multiple dose escalation part: dose 2<br>10 participants will be randomly allocated to active drug or placebo (8 active drug, 2 placebo).
