First seen Jan 05, 2026 · Last updated Jun 16, 2026 · Updated 23 times

Summary

This study is looking at a protein called PSMA in a specific type of advanced breast cancer (HER2-negative, AR-positive). Researchers want to see if PSMA levels on a PET scan can predict whether the cancer will resist a hormone-blocking drug called bicalutamide. About 15 people will join, and the study involves one PET scan and lasts about 3 days. The goal is to better understand treatment resistance, not to test a new treatment.
