About this study

This phase II trial studies how to improve the usage of Lu 177 vipivotide tetraxetan (177Lu-prostate-specific membrane antigen \[PSMA\]-617) for treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site), to other places in the body (metastatic) utilizing a treatment pause after 5 cycles of therapy versus standard continuous treatment for 6 cycles. Lutetium is a radioligand therapy (RLT). RLT uses a small molecule (in this case 177Lu-PSMA-617) that carries a radioactive component to destroy tumor cells. When lutetium is injected into the body, it attaches to the PSMA receptor found on tumor cells. After lutetium attaches to the PSMA receptor, its radiation component destroys the tumor cell. Giving 177Lu-PSMA-617 for 5 cycles versus 6 cycles may better treat patients with metastatic castrate resistant prostate cancer.
