Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a pilot, non-randomized, two-cohort interventional study in patients who meet the inclusion criteria, using an FDA- approved androgen deprivation agent for a 3 or 6-week course of treatment prior to standard-of-care RALP with PLND. The intent of the study is to determine the effect of ADT on PSMA expression as measured by PSMA-PET scan. A second PSMA-PET scan will be performed after ADT for either 3 or 6 weeks, depending on cohort, prior to RALP and PLND.
