New test may predict immunotherapy success in bladder cancer
NCT ID NCT06738797
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new lab test called SPHERTEST to see if it can predict how well bladder cancer patients will respond to immunotherapy. Researchers will take blood and tumor samples from 32 patients with advanced bladder cancer to see if the test's prediction matches real treatment outcomes. The goal is to find a way to personalize treatment and avoid giving ineffective therapies.
