Brief Summary

The immune system helps protect the body from diseases. But, sometimes the immune system can be too sensitive and overreact to very small allergens, like dust and pet dander. This can cause skin conditions like dermatitis and eczema. People with these skin conditions have inflammation that can cause dry, red, and itchy skin. These symptoms often "flare up", meaning that the symptoms come back after being gone for some time. Researchers are looking for a different way to treat people who have skin conditions caused by an overreaction of the immune system. Before a treatment is available to all patients, researchers study it in trials to better understand its safety and how well it works. In this trial, the researchers will learn more about how BAY1834845 and BAY1830839 work and how safe they are in healthy male participants. The trial will include about 72 healthy male participants who are between the ages of 18 and 55. The researchers will use a computer program to randomly choose the treatment each participant will take. This will help make sure the treatments are chosen fairly. Researchers do this so that comparing the results of the treatments is accurate as possible. The participants will be randomly put into 1 of 4 groups. The participants will take their trial treatment 2 times a day for 7 days in a row.

Group 1: BAY1834845 as tablets by mouth
Group 2: BAY1830839 as tablets by mouth
Group 3: A placebo as tablets by mouth
Group 4: Prednisolone as tablets by mouth A placebo looks like a treatment but does not have any medicine in it. Prednisolone is a steroid treatment that is already available for doctors to prescribe to people with skin conditions caused by an overreaction of the immune system. All the participants will also receive imiquimod applied as a cream to their back. All participants will also receive lipopolysaccharide as an intravenous infusion. Imiquimod and lipopolysaccharide will be used to cause irritation and inflammation of the skin and in the blood. The researchers want to see if treatment with BAY1834845 and BAY1830939 can then help reduce these symptoms of irritation and inflammation. In this trial, the researchers will look at:
the change in the amount of blood flow in the participants after imiquimod
the change in how red the participants' skin is after imiquimod
the change in the amount of inflammation applying the participants have after receiving lipopolysaccharide infusion

Outcome Measures

Primary Outcomes (4)

Average change in TNF-α
From pre-challenge up to 6 hour after the systemic challenge
Average change in IL-6
From pre-challenge up to 6 hour after the systemic challenge

Secondary Outcomes (13)

Change of perfusion/basal flow
Pre-challenge and at 24 hour / 48 hour / 72 hour after start of skin challenge

Pre-challenge and at 24 hour / 48 hour / 72 hour after start of skin challenge
Average change of Clinician Erythema Assessment (CEA) score
Pre-challenge and at 24 hour / 48 hour / 72 hour after first administration of skin challenge
Changes in cytokines cells of skin suction blisters
From baseline up to 72 hour after first administration of skin challenge
