In part four of the Radioligands session from Uromigos Live 2024, the expert panel discusses the results of the phase 3 PEACE-3 trial, which evaluates the combination of enzalutamide with or without radium-223 in patients with metastatic castration-resistant prostate cancer. They examine key outcomes, including radiographic progression-free survival and overall survival, with the trial showing a positive impact on both metrics with nearly identical hazard ratios. The discussion touches on the evolving treatment landscape, the historical underutilization of radium-223, and whether this combination should become a new standard of care.
