Radspherin® is a novel alpha-emitting radioactive microsphere designed for treatment of metastatic cancers in body cavities. The radium based therapeutic, Radspherin® has shown strong and consistent anticancer activity at doses being essentially non-toxic in preclinical studies. It is anticipated that the product can potentially treat several forms of metastatic cancer. The first clinical indication for Radspherin® will be treatment of peritoneal carcinomatosis originating from ovarian cancer. Peritoneal carcinomatosis is one of the most serious complications of gastrointestinal and gynecological malignancies.
