Study Summary

This clinical trial investigates the change in prostate-specific membrane antigen (PSMA) expression in response to hormonal therapy in both, Castration Sensitive Prostate Cancer (CSPC) and Castration Resistant Prostate Cancer (CRPC), and whether this change in PSMA expression changes tumor staging after therapy initiation. Understanding these effects can help define the best timing to perform the PSMA positron emission tomography (PET) relative to the start of therapy.

Primary Outcome

Evaluate the change in SUVmax between baseline and Day 8 using a paired t-test to determine how hormonal therapy affects the PSMA modulation.
