Trial Purpose

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

Inclusion Criteria
- Participant must be 18 to 55 years of age inclusive, at the time of signing the informed consent.

- Male.
Exclusion Criteria
- Medical disorder, condition or history of such that would impair the participant's ability to take part in or complete this study in the opinion of the investigator
- A history of relevant diseases of vital organs, of the central nervous system including neuropsychiatric illness or other organs, previous syncope or autoimmune disease such as multiple sclerosis, inflammatory bowel disease, rheumatoid arthritis or other immune-inflammatory diseases.
- Unintended weight loss or gain of at least 5 kg in 4 weeks at screening.
- Any serious concomitant illness that anticipates the need of systemic medication interfering with the study medication.
- A history of trauma with likely damage to the spleen, surgery to spleen or congenital abnormalities of the spleen.
- Hemorrhagic diathesis (easy bruising, epistaxis, gastro-intestinal bleeding).
- History of known pulmonary embolism or known anti-phospholipid syndrome.
- Previous participation in a systemic (i.v./inhalative) lipopolysaccharide (LPS) challenge trial within one year before start of treatment.
- Diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study intervention(s) will not be normal (cholecystectomy permitted).
- Any infection requiring hospitalization, systemic antimicrobial therapy within 60 days, or as otherwise judged to be an opportunistic infection or clinically significant by the investigator, within the past 6 months prior to treatment period.
- Any active or ongoing chronic infectious disease including periodontitis with the exception of common viral or fungal skin infections such as plantar warts or athlete's foot.
- Febrile illness within 30 days before the start of the first study intervention.
- Medical history of sepsis, tuberculosis, increased frequency of infections, immunodeficiency diseases, with recent febrile diseases and anamnestic and/or laboratory signs of an impaired immune status or latent infections (hepatitis B, hepatitis C, and human immunodeficiency virus [HIV]).
- History of COVID-19 within 6 months prior to treatment period or in case of clinically relevant sequela of former COVID-19 (such as fatigue or exercise dyspnea)
- Contact with SARS-CoV-2- positive or COVID-19 patient within the last 2 weeks prior to SARS-CoV-2 viral PCR test (at visit 2).
- History of major surgery within 8 weeks prior to treatment period or scheduled (elective) surgery, planned hospitalization and surgical dental treatment within study and 4 weeks after final follow-up.
- History of or acute atopic dermatitis with active eczematous lesions, bronchial asthma or allergic rhino-conjunctivitis symptomatic during screening period.
- History of other concomitant skin conditions (chronic inflammatory dermatoses) that would interfere with the evaluation of the effect of the study medication on contact dermatitis.
- History of hypersensitivity to any of the components of the study interventions.
- History of malignant tumors (except treated basal cell carcinoma).
- Any clinical contraindications to treatment with steroids, such as uncontrolled hypertension, chronic liver disease (Child–Pugh scores B or C), latent diabetes mellitus, history of gastrointestinal bleeding.
- Use of topical and systemic drugs (prescription or over-the-counter [OTC]) within 30 days or within 5 half-lives (whichever is longer) before start of treatment.
- Use of other investigational drugs within 30 days or within 5 halflives (whichever is longer) of the investigational product before screening.
- Receipt of live or attenuated vaccine (with the exception of adenovirus-vectored SARS-CoV-2 vaccinations) 90 days before start of treatment.
- Vaccination completion (completion of 2nd vaccination shot if applicable) against SARS-CoV-2 or influenza vaccinations less than 15 days prior to first study drug administration. (Vaccines with a single-dose scheme: Receipt of vaccination < 29 days before the planned first administration of the study intervention).
- Phototherapy and extensive sun/ ultraviolet (UV) exposure within 4 weeks prior screening and throughout study.
- Clinically relevant findings in the ECG, blood pressure and pulse rate, which in the opinion of the investigator(s), may put the participant at risk because of his participation in the trial
- Clinically relevant findings in the physical examination, especially skin abnormalities in the application area.
- Clinically relevant deviations of the laboratory parameters from reference ranges at screening, ALT>1.1 x ULN, AST>1.2 x ULN, total bilirubin > ULN, CRP>5 mg/L (above ULN or clinical or laboratory signs of infection) or other clinically relevant laboratory abnormalities.
- Whole blood or red blood cell donation, or any blood loss > 500 mL within 3 months prior to screening or donation of plasma within 14 days prior to screening.
