Oncoinvent AS is a privately held Norwegian company established in 2010. The company is committed to developing new innovative products to provide better treatment options to cancer patients. The innovations being developed by Oncoinvent AS are a result of the extensive experience with the development of radionuclide-based cancer treatments of two of the founders, Dr. Roy H. Larsen and Professor of clinical oncology Øyvind S. Bruland. Larsen and Bruland are the inventors of the first FDA and EMA-approved alpha-emitting pharmaceutical product Xofigo® (Bayer AG), as well as of the beta-emitting radio-immunotherapeutic product candidate Betalutin® (Nordic Nanovector ASA). Oncoinvent's lead product candidate, Radspherin®, is a novel alpha-emitting radioactive microsphere designed for the treatment of metastatic cancers in body cavities. Radspherin® has been shown to cause a significant reduction in tumor cell growth. It is anticipated that the product can potentially treat several forms of metastatic cancer. The first clinical indication for Radspherin® will be the treatment of peritoneal carcinomatosis. Clinical development will be conducted in collaboration with European and American clinical research centers.
