New hope: immune drug may let some bladder cancer patients avoid bladder removal

First seen Apr 17, 2026 · Last updated May 14, 2026 · Updated 4 times

Summary

This study tests whether the immunotherapy drug pembrolizumab can shrink muscle-invasive bladder cancer enough to allow some patients to keep their bladder. About 46 adults with localized cancer will receive pembrolizumab, then be rechecked. If the cancer is gone or nearly gone, they continue on pembrolizumab and are watched closely. If not, they get standard treatment (like surgery or radiation) followed by more pembrolizumab. The goal is to see if this approach can safely spare the bladder while controlling the disease.
