Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called human epidermal growth factor receptor 2 (HER2) mutations.
Advanced NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body or that are unlikely to be cured or controlled with currently available treatments. HER2 is a protein that helps cells to grow and divide. A damage (also called mutation) to the building plans (genes) for this protein in cancer cells leads to a production of abnormal HER2 and therefore abnormal cell growth and division.
The study treatment, BAY 2927088, is expected to block the mutated HER2 protein which may stop the spread of NSCLC.
The main purpose of this study is to learn how well BAY 2927088 works and how safe it is compared with standard treatment, in participants who have advanced NSCLC with specific genetic changes called HER2 mutations.
The study participants will receive one of the study treatments:
* BAY 2927088 twice every day as a tablet by mouth, or
* Standard treatment in cycles of 21 days via infusion ("drip") into the vein. The treatment will continue for as long as participants benefit from it without any severe side effects or until they or their doctor decide to stop the treatment.
During the study, the doctors and their study team will:
* take imaging scans, including CT, PET, MRI, and X-rays, of different parts of the body to study the spread of cancer
* check the overall health of the participants by performing tests such as blood and urine tests, and checking
* heart health using an electrocardiogram (ECG)
* perform pregnancy tests for women
* 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. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.

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 on people with 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.
Researchers think that BAY2927088 might affect an enzyme (called CYP3A4) that breaks down drugs in the body. This might make the effects of some drugs weaker or stronger. Midazolam is a drug that is broken down by CYP3A4. By studying the level of midazolam in the blood, researchers can understand how BAY2927088 might influence this enzyme's activity.
The main purpose of this study is to find out how BAY2927088, taken as a single dose and as multiple doses, affects the level of another drug, called midazolam, in the blood of healthy participants. To achieve this goal, researchers will measure the following for midazolam when participants take it with or without BAY2927088:
* Area under the curve (AUC): a measure of the total amount of midazolam in participants' blood over time
* Maximum observed concentration (Cmax): the highest amount of midazolam in participants' blood
The study will have 3 treatment periods:
Period 1 (Day 1 to Day 2): On Day 1, participants will take midazolam Period 2 (Day 3 to Day 4): On Day 3, participants will take midazolam with BAY2927088 Period 3 (Day 5 to Day 15): On Days 5 to 13, participants will take BAY2927088 On Day 14, participants will take midazolam with BAY2927088
Participants will be part of the study for about 8 weeks with at least 3 visits to the study clinic.
Participants will visit the study clinic:
* More than/at least once, within 2 to 28 days before the treatment starts
* Once on the day before the treatment starts and will stay in the clinic until Day 15 of the treatment
* Once, within 7 to 10 days after they finish treatment for a health checkup
During the study, the doctors and their study team will:
* do physical examinations
* collect blood samples from the participants to measure the blood levels of midazolam and 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. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.
