This clinical trial is focused on studying a type of cancer called dedifferentiated liposarcoma, which is an advanced form of cancer that develops in fat cells. The study aims to compare the effectiveness of a new treatment called brigimadlin (BI 907828) with an existing chemotherapy drug known as doxorubicin. Brigimadlin is taken as a film-coated tablet, while doxorubicin is given as a solution for infusion, which means it is administered directly into the bloodstream through a vein.
The purpose of the study is to determine if brigimadlin is more effective than doxorubicin as a first-line treatment for patients with advanced or metastatic dedifferentiated liposarcoma. Participants in the study will be randomly assigned to receive either brigimadlin or doxorubicin. The study will monitor the progression of the disease and assess the overall survival of the participants. The treatment period for brigimadlin is up to 21 days, while doxorubicin can be administered for a longer period, up to 126 days.
Throughout the study, participants will undergo regular assessments to track their response to the treatment. These assessments will include monitoring for any side effects and evaluating the quality of life through specific questionnaires. The study will also collect blood samples to analyze the drug’s effects on the body and any changes in the tumor. The ultimate goal is to find a more effective treatment option for patients with this challenging type of cancer.
