The goal of the study is to learn about the safety of Sacituzumab Tirumotecan and if people can tolerate it when given in the bladder and find the highest dose that people can take without having certain problems. Researchers will then choose a dose level of Sacituzumab Tirumotecan to use in future studies to learn how well the drug works.
