Basic Information

• Recruitment Status: COMPLETED

Brief Summary

The purpose of the study is to test how well patients with advanced solid tumors respond to treatment with elimusertib (BAY1895344) in combination with pembrolizumab. In addition researchers want to find for patients the optimal dose of elimusertib in combination with pembrolizumab, how the drug is tolerated and the way the body absorbs, distributes and discharges the drug. The study medication, elimusertib, works by blocking a substance (ATR Kinase) which is produced by the body and is important for the growth of tumor cells. Pembrolizumab is an immunologic checkpoint blocker that promotes an immune response against the tumor.
