“Radium-223 dichloride (Xofigo) opened an entirely new chapter in the treatment landscape of castration-resistant prostate cancer with bone metastases (mCRPC), says E. David Crawford, MD, professor of Radiation Oncology, Department of Surgery, at the University of Colorado Denver.
“ ‘Radium-223 is sort of a surprise drug, at least to me,’ says Crawford. “We have had radioisotopes around for a long period of time, including phosphorus-32, samarium-153 (Quadramet), strontium-89 (Metastron), and others. But, they all had a lot of baggage with them, in terms of side effects.
” ‘Now, we have a new one—radium-223—which is not associated with the side effects that we were seeing with the other ones, but it is associated with an improvement in survival rate. It’s a game changer.’ ”
