CHICAGO, IL January 20, 2015 (PRNewswire) – Positron Corporation (OTCBB:POSC) is pleased to announce that the United States Patent and Trademark Office (USPTO) has awarded the Institute for Nuclear Research (INR) of the Russian Academy of Sciences a patent (U.S. No. 8,929,503) for the method for producing strontium-82 (Sr-82) - a precursor to rubidium-82 (Rb-82), the leading radiopharmaceutical used in Positron Emission Tomography (PET) myocardial perfusion imaging. It is the second patent for this technology in North America included in a license agreement between INR and Positron Corporation: INR has been awarded a Canadian patent (CA 2719347) for the same technology in July 2014. The rights to this patented technology have been granted by INR to Positron Corporation. Although other licensees, from France and Russia, can sell Sr-82 produced with the patented technology, only Positron Corporation has the right to utilize the technology in North America.
The Sr-82 production technology was developed by Dr. Воris Zhuikov, Head of the Laboratory Radioisotope Complex and colleagues at INR. The developed technology has significant environmental and economic benefits, as it simplifies the production process while markedly increasing the yield and quality of the Sr-82 product derived from rubidium metal.
This improved rubidium metal Sr-82 production process, currently practiced in Russia as well as by a French radioisotope production facility, will be applied to future rubidium metal target processing at Positron’s Texas facility. The significant aspect of this technology is the potential realization of real-time, continuous Sr-82 production using a rubidium metal target loop on Positron’s proposed 70 MeV cyclotron.
“Positron has been a strong advocate of the advancement, maturation, and implementation of this patented technology”, stated Jason Kitten, Executive Director of Radioisotopes for Positron Corporation. “We look forward to working with INR in building up the strontium-82 production infrastructure in the US and applying this proven radiostrontium production to our production capability. “
