A Study to Determine How BI 907828 (Brigimadlin) is Taken up in the Tumor (Phase 0) and to Determine the Highest Dose of BI 907828 (Brigimadlin) That Could be Tolerated (Phase 1a) in Combination With Radiation Therapy in People With a Brain Tumor Called Glioblastoma

Study Purpose

This study is open to adults with newly diagnosed glioblastoma, a type of brain tumor. The study has two parts. Part 1 is open to people who can get their brain tumor removed by surgery. Part 2 is open to people who already had such a brain surgery. This study tests a medicine called BI 907828 (Brigimadlin). BI 907828 (Brigimadlin) is a socalled MDM2 inhibitor that is being developed to treat cancer. The purpose of Part 1 of the study is to find out how BI 907828 (Brigimadlin) is taken up in the tumor. Participants take a single dose of BI 907828 (Brigimadlin) as a tablet before the brain surgery. Part 1 of the study takes about 1 month. During this time, participants have their brain tumor removed by surgery and visit the study site about 8 times. The purpose of Part 2 is to find the highest dose of BI 907828 (Brigimadlin) that the participants can tolerate in combination with standard radiation therapy. During the first 6 weeks, participants get standard radiation therapy. In addition, they take a dose of BI 907828 (Brigimadlin) once every 3 weeks. Participants may continue to take BI 907828 (Brigimadlin) as long as they benefit from treatment and can tolerate it. They visit the study site regularly. During the entire study, doctors also regularly check participants' health and take note of any unwanted effects.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over

- Patient has undergone neurosurgical tumor resection and is eligible for standard radiotherapy.

- Patients must be neurologically stable based on the judgement of the treating physician.

The use of corticosteroids and anti-seizure medication is allowed and should be at a stable or decreasing dose for at least 7 days before inclusion in the trial. Anti-seizure medication should not include agents that interact with BI 907828 (Brigimadlin).

- For patients, who have participated in Phase 0, the interval between the single dose of BI 907828 (Brigimadlin) and subsequent Phase 1a treatment must be at least 21 days.

Further inclusion criteria applies. Exclusion criteria.

- Exclusion criteria Part Phase Ia: - Patients who have received previous systemic therapy (with the exception of patients who participated in Phase 0) or radiotherapy for glioblastoma.

- Patients who must or intend to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial.

- Patients with pacemakers or other metallic implants that can interfere with the magnetic field during MRI investigations.

- Inability to undergo contrast-enhanced MRI (GFR <30 mL/min).

Further exclusion criteria applies.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05376800
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1
