About this trial

This clinical trial studies mechanisms of resistance to 177-lutetium prostate specific membrane antigen (177Lu-PSMA) radioligand therapy using image-guided biopsies in patients with castrate-resistant prostate cancer that had spread to other places in the body (metastatic). Diagnostic procedures, such as image guided biopsies, may help in learning how well 177Lu-PSMA works to kill tumor cells and allow doctors to plan better treatment.
