About Radspherin

Radspherin® is an investigational radiopharmaceutical designed for the local
treatment of cancer that has spread to body cavities. It consists of calcium
carbonate microparticles containing the radioactive material radium-224. The
mode of action is the decay of radium-224 emitting alpha-particles, a highly
potent form of ionizing radiation. Radspherin® is investigated in clinical
studies to treat peritoneal carcinomatoses from ovarian and colorectal cancer
and it is administered intraperitoneally after surgical resection with removal
of all macroscopic tumors.
