Brief Summary

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

This study is open to adults with a type of cancer called dedifferentiated liposarcoma (DDLPS). They can join the study if their tumours are positive for MDM2. The purpose of this study is to find out whether a medicine called brigimadlin (BI 907828) is tolerated by and helps people with DDLPS. Brigimadlin is a so-called MDM2 inhibitor that is being developed to treat cancer.

Participants take brigimadlin as a tablet once every 3 weeks. Participants may continue to take brigimadlin as long as they benefit from treatment and can tolerate it. They visit the study site regularly. At the study site, doctors regularly check participants' health and take note of any unwanted effects. The doctors also regularly check tumour size.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Provision of signed and dated, written informed consent form (ICF) in accordance with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) - Good Clinical Practice (GCP) and local legislation prior to any study-specific procedures, sampling, or analyses
2. Male or female patients ≥18 years old at the time of signature of the ICF
3. Women of childbearing potential (WOCBP) and men able to father a child must be ready and able to use two medically acceptable methods of birth control per ICH M3 (R2) that result in a low failure rate of \<1% per year when used consistently and correctly beginning at screening, during study participation, and until 6 months and 12 days after last dose for women and 102 days after last dose for men. A list of contraception methods meeting these criteria is provided in the patient information
4. Histologically documented locally advanced or metastatic, unresectable (i.e. surgery morbidity would outweigh potential benefits), progressive or recurrent Dedifferentiated liposarcoma (DDLPS), meeting the criteria for an open study cohort:

* Cohort A: patient has not received prior systemic therapy for DDLPS in any setting (including adjuvant, neoadjuvant, maintenance, palliative)
* Cohort B: patient has received any prior systemic therapy for DDLPS in any setting (including adjuvant, neoadjuvant, maintenance, palliative)
5. Written pathology report indicating the diagnosis of DDLPS with positive MDM2 immunohistochemistry or MDM2 amplification as demonstrated by fluorescence in situ hybridisation (FISH) or next-generation sequencing (NGS)
6. Presence of at least 1 measurable target lesion according to RECIST version 1.1. In patients who only have 1 target lesion, the baseline imaging must be performed at least 2 weeks after any biopsy of the target lesion
7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Exclusion Criteria

1. Known mutation in the TP53 gene (screening for TP53 status is not required)
2. Major surgery (major according to the investigator's assessment) performed within 4 weeks prior to start of study treatment or planned within 6 months after screening
3. Previous administration of brigimadlin or any other MDM2-p53 or MDM4 regulator of p53 (MDM4/MDMX)-p53 antagonist
4. Previous treatment in study 1403-0008 (Brightline-1)
5. Having to receive, or intending to receive, restricted medications or any drug considered likely to interfere with the safe conduct of the study
6. Receiving treatment for brain metastases or leptomeningeal disease (LMD) which may interfere with safety and/or endpoint assessment
7. Unable to swallow the study treatment
