Effect of Androgen Receptor Signaling Inhibitors on 68Ga-PSMA-11 PET/CT Imaging in Patients With Castration-Resistant Prostate Cancer

Summary

This trial studies the effect of androgen receptor signaling inhibitors on 68Ga-PSMA-11 PET/CT imaging in patients with castration-resistant prostate cancer that has spread to other places in the body (metastatic). Diagnostic procedures, such as 68Ga-PSMA-11 PET/CT, may help in learning how well androgen receptor signaling inhibitors work in killing castration-resistant prostate cancer cells and allow doctors to plan better treatment.
