Summary

This study tests a new drug, BI 1703880, combined with ezabenlimab in adults with advanced solid tumors that haven't responded to other treatments. The main goal is to find a safe dose of BI 1703880. Participants receive both drugs as infusions, with BI 1703880 given weekly then every 3 weeks, and ezabenlimab every 3 weeks. The study focuses on safety and how the body processes the drugs, not on curing the cancer.
