First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

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