Study Summary

This study is being done to see how well two drugs (enfortumab vedotin and pembrolizumab) work together to treat patients with urothelial cancer. The study will compare these drugs to other drugs that are usually used to treat this cancer (standard of care). The patients in this study will have cancer that has spread from their urinary system to other parts of their body.

Primary Outcome

PFS was defined as the time from date of randomization to first documentation of disease progression (PD), or to death due to any cause, whichever occurred first. PD: at least a 20 percent (%) increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeter (mm). PD could also be unequivocal progression of non-target lesions or the presence of
