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

Summary
Brief summary
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.
