Summary
This study tests a new radioactive tracer called 64Cu-GRIP B, which attaches to a protein (granzyme B) made by immune cells. By using PET scans, doctors hope to see which tumors are responding to immunotherapy. The trial involves about 91 adults with advanced prostate, kidney, or bladder cancers. The main goal is to check safety and see if the tracer can help predict treatment success.
