The patent relates to a particle or pharmaceutical composition comprising one or more particles, or a suspension of same or different particles comprising a degradable compound and an alpha emitting radionuclide and/or a radionuclide generating alpha emitting daughter. The particles are beneficial for use in the treatment of cancer.
Jan A. Alfheim, Oncoinvent’s CEO commented: “This is a significant milestone in the development of our lead product candidate, Radspherin™. With this first patent we have gained a solid protection of Radspherin™ until 2035 in what we believe will be a very significant future market for the product. Our Radspherin™ patent applications include claims on composition of matter as well as various medical and medical device applications. The current applications and this issued patent are therefore very broad and cover a wide spectrum of Radspherin™ particle variants and applications.”
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.
