Trial Summary

What is the purpose of this trial?The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic, pharmacodynamic profile of M9466 with and without tuvusertib or an ARPi and early signs of clinical activity of M9466 with tuvusertib in participants with advanced solid tumors. Study details include: Study/Treatment Duration: Participants will be treated until disease progression, death, discontinuation, or End of Study.
