Summary

This study looked at whether genetic changes found in urine can match those found in tumor tissue for people with high-risk bladder cancer that hasn't spread into the muscle. The goal was to see if a urine test could help doctors choose the right immunotherapy for each patient. The study planned to enroll 20 adults who had not received certain prior treatments, but it was terminated early.
