This unique therapeutic approach "stands in strong distinction to zoledronic acid and denosumab, both of which improve SREs but which do not improve survival," notes lead investigator A. Oliver Sartor, MD, Tulane Cancer Center.
Radium-223 works by binding to stoma adjacent to bone metastases, where it then acts like a small bomb. The bursts of emitted alpha particles penetrate a diameter of only 2 to 10 cells, breaking DNA along the way to result in highly localized tumor cell killing but in only minimal damage to normal surrounding tissue.
