Summary
The ATR (ataxia-telangiectasia and Rad3 related protein) inhibitor BAY1895344 is
developed for the treatment of patients with advanced solid tumors and lymphomas. The
purpose of the proposed trial is to evaluate the safety and tolerability of BAY1895344,
and to identify the maximum tolerated dose of BAY1895344 that could be safely given to
cancer patients. Further, the response of the cancer to the treatment will be determined.
