Summary
The main goals of this study are to learn about the safety of sacituzumab tirumotecan with bevacizumab and if people tolerate it; and if people who take sacituzumab tirumotecan with or without bevacizumab live longer without the cancer getting worse than those who receive standard of care treatment.
