New Radspherin® data published

Oncoinvent is pleased to announce today that Oncoinvent researchers have published data demonstrating the efficacy of the Radspherin® in two separate models of peritoneal carcinomatosis originating from ovarian cancer cell lines in the journal Translational Oncology.

Summary of findings

In both models, intraperitoneal treatment with Radspherin® gave significant antitumor effect with either considerably reduced tumor volume or a survival benefit. An advantageous discovery was that only a few kilobecquerels were needed to yield therapeutic effects. The treatment was well tolerated up to a dose of 1000 kBq/kg with no signs of acute or subacute toxicity observed. Intraperitoneal α-therapy with Radspherin® demonstrated a  significant potential for treatment of peritoneal micrometastases in ovarian carcinoma.

About Radspherin®

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 without any signs of product related toxicity 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. Peritoneal carcinomatosis is one of the most serious complications of gastrointestinal and gynecological malignancies.
