Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study has 2 parts. The first part of the study is done. The first part was open to adults with different types of advanced cancer (solid tumors). The second part is open to people with specific types of soft tissue sarcoma, advanced lung cancer, and cancer in the stomach, bladder or bile ducts.

The participants get a combination of 2 medicines called brigimadlin (also called BI 907828) and ezabenlimab (also called BI 754091). Brigimadlin is a so-called MDM2 inhibitor that is being developed to treat cancer. Ezabenlimab is an antibody that may help the immune system fight cancer (immune checkpoint inhibitor). When the study started, some participants got a third medicine called BI 754111 in addition. Treatment with BI 754111 was stopped because data from another study showed no additional effect of BI 754111.

The purpose of the first part of the study was to find out the highest dose of brigimadlin that the participants could tolerate in combination with ezabenlimab. This dose is used in the second part of the study.

The purpose of the second part is to see whether the combination of brigimadlin with ezabenlimab is able to make tumors shrink.

The participants are in the study as long as they benefit from treatment and can tolerate it.

Ezabenlimab treatment is limited to 2 years. During this time, they get infusions of ezabenlimab, and take tablets with brigimadlin every 3 weeks. The doctors check how many participants have health problems during the study. The doctors also monitor the size of the tumor.

* Major surgery (major according to the Investigator's assessment) performed within 12 weeks prior to start of study treatment, or planned within 12 months after screening (e.g. hip replacement).
* Any other documented active or suspected malignancy or history of malignancy within 3 years prior to screening, except appropriately treated basal cell carcinoma of the skin or in situ carcinoma of uterine cervix, or other local tumors considered cured by local treatment.
* Patients who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial.
* Currently enrolled in another investigational device or drug trial, or less than 4 weeks since receiving other investigational treatments. Patients who are in follow-up/observation for another clinical trial are eligible.

* Serious concomitant disease or medical condition affecting compliance with trial requirements or which are considered relevant for the evaluation of the efficacy or safety of the trial drug, such as neurologic, psychiatric, infectious disease or active ulcers (gastro-intestinal tract, skin) or laboratory abnormality that may increase the risk associated with trial participation or trial drug administration, and in the judgment of the Investigator, would make the patient inappropriate for entry into the trial.
* Chronic alcohol or drug abuse or any condition that, in the Investigator's opinion, makes them an unreliable trial patient or unlikely to complete the trial.
* Women who are pregnant, nursing, or who plan to become pregnant while in the trial; female patients who do not agree to the interruption of breast feeding from the start of study treatment to within 30 days after the last study treatment.

* Active infection requiring systemic treatment (antibacterial, antiviral, or antifungal therapy) at start of treatment in this trial.
* Any of the following cardiac criteria:

* Mean resting corrected QT interval (QTc) \>470 msec
* Any clinically important abnormalities (as assessed by the Investigator) in rhythm, conduction, or morphology of resting ECGs, e.g., complete left bundle branch block, third degree heart block
* Any factor that increases the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years-of-age, or any concomitant medication known to prolong the QT interval
* Patients with an ejection fraction (EF) \<50% or the lower limit of normal of the institutional standard will be excluded. Only in cases where the Investigator (or the treating physician or both) suspects cardiac disease with negative effect on the EF, will the EF be measured during screening using an appropriate method according to local standards to confirm eligibility (e.g., echocardiogram, multi-gated acquisition scan). A historic measurement of EF no older than 6 months prior to first administration of study drug can be accepted provided that there is clinical evidence that the EF value has not worsened since this measurement in the opinion of the Investigator or of the treating physician or both.
