Clinical Trial Summary

This is a single sequence 2-period open label study in participants with advanced solid tumors. The purpose of Period 1 of this study is to assess the mass balance to determine drug-related entities present in circulation and excreta and provide a comprehensive understanding of biotransformation pathways and clearance mechanisms in participants with advanced solid tumors. Thereafter, participants may enter an optional extension phase (Period 2) where participants will receive M1774 until disease progression or other criteria for study intervention discontinuation are met.
