A First-in-human Study to Learn How Safe the Study Treatment BAY2862789 is, to Find the Best Dose, How it Affects the Body, What Maximum Amount Can be Given, How it Moves Into, Through and Out of the Body, and How it Acts on Different Tumors in Participants With Advanced Solid Tumors

Study Summary

Researchers are looking for a better way to treat people who have advanced solid tumors including a specific kind of lung cancer (non-small cell lung cancer, NSCLC). Advanced solid tumors are types of cancer that have spread to nearby tissue, lymph nodes, and/or to distant parts of the body and that are unlikely to be cured or controlled with currently available treatments. BAY2862789 works by blocking an enzyme in T-cells, thereby activating them. T-cells are a type of immune cell that are known to have an anti-cancer effect. The main purpose of this first-in-human study is to learn: * how safe different doses of BAY2862789 are, * the degree to which medical problems caused by BAY2862789 can be tolerated (also called tolerability), * what maximum amount (dose) can be given, and * how BAY2862789 moves into, through and out of the body. To answer this, the researchers will look at: * the number and severity of medical problems participants have after taking BAY2862789 for each dose level. These medical problems are also referred to as adverse events. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important. * the (average) total level of BAY2862789 in the blood (also called AUC) after intake of single and multiple doses. * the (average) highest level of BAY2862789 in the blood (also called Cmax) after intake of single and multiple doses. Doctors and their team keep track of all medical problems that participants have during the study, even if they do not think the medical problem might be related to the study treatment. In addition, the researchers want to know if and how the participants' tumors change after taking BAY2862789. The dose escalation will be done to find the most appropriate dose that can be given. For this, each participant will receive one of the increasing doses of Bay 2

Primary Outcome

Adverse events (AEs) will be considered treatment-emergent if they have started or worsened after first administration of study treatment up to 90 days after the last administration of study treatment.
