A Study to Learn About How Food and Esomeprazole Affect the Level of BAY2927088 in the Blood When Taken Together in Healthy Participants

Plain-language summary

Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) mutations. Advanced NSCLC refers to a type of lung cancer that has spread from the lungs to nearby tissues or other body parts. People with advanced NSCLC may have changes in certain proteins, like EGFR and HER2, that cause uncontrolled cell growth and increased spread of cancer. In this study, participants will be healthy and will not benefit from taking the study treatment, BAY2927088. However, the study will provide information about how to test BAY2927088 in future studies with people who have advanced NSCLC with EGFR or HER2 mutations. BAY2927088 is under development for the treatment of advanced NSCLC with EGFR or HER2 mutations. It is expected to work against these changed proteins, which might slow down the spread of cancer. The absorption of BAY2927088 into the blood is dependent on the amount of acid present in the stomach. Esomeprazole is a medicine which is used in the treatment of heartburn and excessive acid in the stomach. Both food and esomeprazole may change the amount of acid present in the stomach. The main purpose of this study is to find out how food and esomeprazole may affect the absorption of BAY2927088 into the blood of healthy participants. For this, researchers will measure the levels of BAY2927088 in participants' blood when it is given with or without food as well as with or without esomeprazole. Researchers will then calculate the following: * Area under the curve (AUC): a measure of the total amount of BAY2927088 in participants' blood over time * Maximum observed concentration (Cmax): the highest amount of BAY2927088 in participants' blood The study will have 4 treatment periods: \- Periods 1 to 3 (Day 1 to Day 9): All participants will take BAY2927088 with a low-fat meal, with a high-fat meal, and on an empty stomach, but in a different order, over the 3 study periods. Each period will last for 3 days and BAY2927088 will be given on the first day of each period. On Day 9, participants will take esomeprazole on an empty stomach. \- Period 4 (Day 10 to Day 14): On Days 10 and 11, participants will take esomeprazole on an empty stomach. On Day 12, participants will take esomeprazole on an empty stomach. After 1 and a half hours, participants will take low-fat meal and BAY2927088. On Day 13, participants will take esomeprazole on an empty stomach. Participants will be in this study for about 8 weeks with 3 visits to the study clinic. Participants will visit the study clinic: * at least once, 2 to 28 days before the treatment starts, to confirm they can take part in this study * once on the day before the treatment starts and will stay in the clinic until Day 14 of the treatment * once, 7 to 10 days after last dose of BAY2927088, for a health check-up During the study, the doctors and their study team will: * do physical examinations * collect blood samples from the participants to measure the levels of BAY2927088 * check participants' health by performing tests, such as blood and urine tests, and checking heart health using an electrocardiogram (ECG) * ask the participants questions about how they are feeling and what adverse events they are having An adverse event is any medical problem that a participant has during a study. The study doctors keep track of all adverse events, irrespective of whether they think it is related or not to the study treatment.
