‒ Recognizing RadioGenix® System contributions in addressing ongoing Mo-99 supply shortages by providing customers with nearly a year of continuous medical radioisotope supply since launch ‒

Beloit, Wis., October 14, 2019 – NorthStar Medical Radioisotopes, LLC, a global innovator in the production and distribution of radioisotopes used for medical imaging, announced that it hosted a ribbon-cutting, groundbreaking and speakers event, “Molybdenum-99: Domestic Radioisotope Production Now, Expansion for the Future,” at its headquarters in Beloit, Wis. on September 19, 2019. The event commemorated nearly a year of continuous domestic molybdenum-99 (Mo-99) supply for U.S. healthcare providers, demonstrated progress on NorthStar’s expansion plans and included discussions about current and future U.S. supply of important medical radioisotopes by representatives from the U.S. Department of Energy’s National Nuclear Security Administration (DOE/NNSA), State of Wisconsin, medical societies and RadioGenix System customers. It also featured a ceremonial ribbon-cutting for NorthStar’s new isotope processing facility to further increase domestic, non-highly enriched uranium-based Mo-99 production capacity, and a groundbreaking ceremony for an electron beam accelerator facility for expanded, highly efficient Mo-99 production. The FDA-approved and commercially available RadioGenix System (technetium 99m generator) is an innovative, high tech radioisotope separation platform for use in producing the widely used medical radioisotope technetium-99m (Tc-99m) from non-uranium-based Mo-99.

Highlights of the Event
“This is an exciting time for NorthStar as we advance our plans to ensure reliable, non-uranium based radioisotope supply for the United States,” said Stephen Merrick, President and Chief Executive Officer of NorthStar. “We are appreciative to all our partners who are making this success possible: the U.S. Department of Energy’s National Nuclear Security Administration and National Laboratories, the U.S. Food and Drug Administration, the Nuclear Regulatory Commission, our private commercial investors, NorthStar’s dedicated and talented employees, our supply chain partners and our customers. In particular, we are grateful for the important contribution that our partner the University of Missouri University Research Reactor (MURR®) Team has made to our program. Additionally, the expansion activities here in Beloit are supported by Corporate Contractors Incorporated (CCI), the lead contractor for the isotope processing facility project, Von Gahlen (a leading global supplier of state-of-the-art shielding solutions for nuclear medicine and radiopharmacy) and IBA (Ion Beam Applications, a leading global supplier of accelerators, focused on bringing integrated and innovative solutions for the diagnosis and treatment of cancer).

“The installed base of RadioGenix Systems continues to grow in line with our plan. The system is increasingly providing customers with the important medical diagnostic imaging radioisotope, Tc-99m, for patients’ diagnostic imaging tests, on time and when they need them. During the almost eleven months since becoming commercially available, RadioGenix Systems have provided continuous, undisrupted domestic Mo-99 supply to meet customer and patient needs for Tc-99m. During the same time period, Mo-99 supply from the current supply chain, which relies on overseas nuclear reactors and processors, has been, and continues to be, impacted by almost weekly disruptions, some being pronounced and lengthy.

“With our partners at MURR®, NorthStar is consistently providing domestic, non-uranium based Mo-99 now, and actively planning for the future. Upon appropriate licensure and FDA approval, our isotope processing facility in Beloit will augment current processing at MURR, providing dual production hubs for Mo-99. This new facility will enable us to more than double production of source vessels, which are used by radiopharmacies with RadioGenix Systems to produce Tc-99m for physicians and their patients. We are working toward final validation of two state-of-the-art fill lines at our Columbia, Missouri facility that, pending expected FDA approval, will further substantially increase the number of Mo-99 source vessels that we are able to ship to customers weekly. The first two accelerators are already ordered for our 20,000 square foot accelerator facility expansion. We plan to use the accelerators to expand production capacity, enhance production efficiencies and create dual manufacturing operations to further secure reliable, non-uranium based Mo-99 radioisotope supply for U.S. customers and patients.

Mr. Merrick continued, “NorthStar’s mission is to ‘transform medical radioisotopes,’ and we are doing that in two ways: first, by generating isotopes using stable starting material and minimizing waste; and secondly, by building efficiencies into the radioisotope production process. In addition to the facility expansions, planned RadioGenix System enhancements and ongoing R&D activities, NorthStar is making important progress in achieving its vision to be a leading medical radioisotope production company.”

In his keynote address, “Transformation of the Mo-99 Industry”, Jeffrey Chamberlin, Senior Advisor, DOE/NNSA, spoke about NorthStar’s progress in the context of larger global efforts to transform the Mo-99 industry. He said it was crucial to ensure that patients in the United States and around the world have sustainable, reliable access to critical and lifesaving medical radioisotopes, while minimizing the use of highly enriched uranium in civilian applications. Through its cooperative agreement program, DOE/NNSA partners with industry and brings U.S. government resources to bear in addressing issues around national security and medical isotope supply. The objective of DOE/NNSA’s efforts is to establish reliable supplies of Mo-99 to meet U.S. patient needs, while advancing U.S. nuclear nonproliferation policy by eliminating the use of proliferation-sensitive highly enriched uranium in medical isotope production around the world.

Mr. Chamberlin also spoke about DOE/NNSA’s experience in working with NorthStar over the past eight years and the company’s plans to be able to produce significant volumes of the U.S. demand for Mo-99 to meet patients’ needs. DOE/NNSA has provided NorthStar with funding to accelerate its efforts and made available the scientific, engineering and technical power of its National Laboratories to advance development of NorthStar’s technology. Mr. Chamberlin commented, “We are proud to work with multiple innovative cooperative agreement partners and proud to have played a role in Northstar’s transformation of this beautiful plot of land here in Beloit into a complex that will profoundly and positively affect the daily lives of many Americans. NNSA applauds NorthStar for its innovation and execution in turning its vision of producing domestic Mo-99 into a reality. Substantial progress has been made in advancing new production technologies that will allow us to diversify the means of Mo-99 production so that the industry is no longer reliant on a single-point-of-failure technology. NorthStar’s leadership in this area is evident by its development of both neutron capture and accelerator technologies.

A number of dignitaries from Wisconsin participated in the event, including Joel Brennan, Secretary of the Wisconsin Department of Administration, Lori S. Curtis Luther, Beloit City Manager and Diane M. Hendricks, Chairperson, Hendricks Holding Co., Inc. They spoke about the importance of NorthStar’s efforts to patient healthcare, the environment and national security, and the positive impact of its innovative technology in job creation and creation of economic opportunities for Beloit, Rock County and the State of Wisconsin.

Representatives from leading nuclear medicine societies spoke at the event. Dr. Munir Ghesani, MD, FACNM, FACR, NYU Langone Health, New York, NY, Advocacy Domain Chair, Government Relations Committee, Society of Nuclear Medicine and Molecular Imaging, spoke about the importance of reliable Tc-99m supply from his perspective as a practicing radiologist and professor at New York University Langone Health. Dr. Ghesani detailed the attributes that make the Tc-99m radioisotope attractive for clinical use, such as its favorable half-life, low radiation dose to patients and its ability to provide prognostic as well as diagnostic information in cardiovascular diagnostic imaging. Kathleen Flood, CEO, American Society of Nuclear Cardiology, spoke about the importance of a consistent and reliable supply of Tc-99m for cardiovascular and other medical imaging procedures. She explained that cardiac SPECT imaging, the standard of care and most widely used advanced cardiac imaging test, could not be performed for many of today’s cardiovascular patients without access to a reliable Mo-99 supply.

Customer perspectives on the medical radioisotope supply chain for Mo-99 were provided by Chris Vessel, U.S. Nuclear Medicine Supply Chain Leader, and Charlie Shanks, Principal Engineer, both of GE Healthcare. Mr. Vessel described the current global supply chain and the effects that several years of near weekly Mo-99 supply disruptions have had on radiopharmacy operations, and efforts by GE Healthcare to source new, local reliable suppliers. He spoke about how now having RadioGenix Systems available in certain GE Healthcare radiopharmacies is making a positive impact in meeting demand during supply shortages. Mr. Shanks spoke about the various ways of producing both high-specific activity Mo-99 using traditional uranium-based methods, and the low-specific activity, non-uranium based approach used in the RadioGenix System. He described features of the product including a novel, innovative sterilization system. Mr. Shanks also highlighted NorthStar’s well-executed technology development in advancing from a concept to providing real-world solutions.
