This clinical trial is focused on studying the effects of a new treatment called BI 907828 on certain types of cancer. The cancers being studied include biliary tract cancer, which affects the bile ducts, gallbladder, and ampulla of Vater; pancreatic cancer, specifically pancreatic ductal adenocarcinoma; lung cancer, specifically lung adenocarcinoma; and bladder cancer, specifically urothelial bladder cancer. These cancers are known to be locally advanced or have spread to other parts of the body, making them challenging to treat with standard therapies.
The purpose of this study is to evaluate how effective and safe BI 907828 is when used alone in treating these cancers. The study will involve patients who have specific genetic characteristics, such as MDM2 amplification and TP53 wild-type status, which are important for the treatment to potentially work. Participants will take the medication in the form of a film-coated tablet by mouth. The study will monitor the patients over a period of time to see how their cancer responds to the treatment and to check for any side effects.
Throughout the study, patients will be closely observed to assess the treatment’s impact on their cancer and overall health. The study aims to gather information on how long the treatment can control the disease, how long patients live after starting the treatment, and any changes in their quality of life. This information will help determine if BI 907828 could be a beneficial treatment option for these types of cancer in the future.
