This study will address health authorities' requests to determine whether moderate and severe renal impairment have an impact on the biodistribution, dosimetry and safety of lutetium (177Lu) vipivotide tetraxetan (AAA617) administered to participants with progressive PSMA-positive metastatic castration-resistant prostate cancer. The study will also characterize the risk of QT prolongation of AAA617 in this participant population.
