First seen Mar 04, 2026 · Last updated May 14, 2026 · Updated 8 times

Summary

This study tests whether starting immunotherapy early, based on a sensitive blood test that finds tumor DNA, can better control metastatic bladder cancer after bladder removal surgery. About 154 adults with signs of cancer in their blood, with or without visible tumors on scans, will receive the treatment. The goal is to see if this approach leads to complete response and helps identify who benefits most.
