Corporate development and industry leadership
NorthStar is firmly positioned for long term growth and increasing global industry leadership.

• In March 2021, NorthStar implemented organizational changes to drive focused growth for its therapeutic and specialized SPECT radioisotopes business. The new structure enables NorthStar to advance its radioisotope development and commercialization planning efforts in parallel with ongoing expansion programs for increased U.S. Mo-99 capacity and production. In conjunction with other organizational changes, NorthStar appointed Dave Wilson, RPh, BCNP, as Vice President, Advanced Radiopharmaceutical and Therapeutic Technologies to lead these initiatives to commercialization.
• In October 2020, NorthStar promoted Chief Financial Officer Paul Estrem to Executive Vice President and he was appointed to the NorthStar Board of Managers. Mr. Estrem has been instrumental in building momentum to create and expand NorthStar’s product portfolio. The expanded role positions him to guide NorthStar’s corporate strategy and drive its planned corporate and business development initiatives.
• NorthStar is a widely recognized leader in radioisotope technology development and commercialization and the nuclear medicine industry. In July 2020, NorthStar led an update on its ongoing commercial Mo-99 production, expansion plans and the RadioGenix System at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) event, “Industry Outlook on Current and Future Mo-99 Supply.” In September 2020, then-Deputy Secretary of Energy Mark W. Menezes visited NorthStar to learn about its U.S.-based Mo-99 production, underscoring the Department of Energy’s commitment to reviving and expanding the U.S. nuclear sector and to reduce dependence on foreign imports while bringing new opportunities to the heartland.

RadioGenix System commercial progress
NorthStar’s innovative, high tech radioisotope separation platform, the RadioGenix System, uses U.S.-produced, non-uranium based Mo-99 to produce Tc-99m, the most widely used medical radioisotope that informs patient management decisions in 40,000 U.S. imaging studies daily.

• RadioGenix System sales continue to steadily increase, with hundreds of thousands of doses provided for patients’ diagnostic imaging studies to date. Since becoming commercially available, RadioGenix Systems have provided reliable Tc-99m supply for customers with U.S.-produced Mo-99, despite intermittent shortages from suppliers using legacy, uranium-based production methods.
• Ongoing product development programs continue to maximize operational utility and efficiency in producing Tc-99m. Since initial approval in 2018, NorthStar has received five subsequent Food and Drug Administration (FDA) approvals, the latest in January 2021 for concentrated Mo-98 and RadioGenix System updates.

Commercial U.S. Mo-99 manufacturing and production expansion
NorthStar is the only commercialized U.S. producer of Mo-99. It is aggressively expanding and establishing dual production and processing hubs for additional Mo-99 capacity to better meet customer demand and to ensure sustainable U.S. supply. Two facility expansion projects nearing completion in Beloit, Wisconsin, will augment current Mo-99 production and processing in Columbia, Missouri, conducted in partnership with the University of Missouri Research Reactor (MURR®).

• NorthStar’s Isotope Processing facility in Beloit will complement current Columbia processing capacity for Mo-99 source vessels. The facility will enable NorthStar to more than double its production of Mo-99, used with RadioGenix Systems to produce Tc-99m. Equipment installation is nearing completion, testing is underway with full qualification to be completed by the end of 2021. NorthStar expects FDA approval for the Beloit Isotope Processing facility in 2022.
• NorthStar’s Accelerator Production facility expansion in Beloit will ensure additional Mo-99 capacity, enable flexible production scheduling and minimize customer supply risks. Like other NorthStar processes, accelerator production of Mo-99 using the “neutron knock-out” method is non-uranium based and highly efficient. The first pair of IBA electron beam accelerators will arrive for installation at NorthStar’s facility in April 2021. The Company anticipates accelerator production to begin in 2023, pending appropriate licensure and FDA approval.
• In January 2021, the FDA approved NorthStar’s process for producing Mo-99 from concentrated Mo-98 and related software updates for the RadioGenix System. This approval is the first and only commercial-scale production of Mo-99 using concentrated Mo-98 technology. It increases NorthStar’s Mo-99 production capacity up to four times above its current technology, to provide higher activity source vessels to better meet customer demand.
• FDA approval of concentrated Mo-98 allows NorthStar to serve as much as 40% of the U.S. demand for Mo-99 by the end of 2021. The Company expects that within three to five years, it will have the capability to regularly supply an estimated 65% of U.S. Mo-99 demand, and up to 100% of U.S. demand in an emergency.

Commercial-scale therapeutic radioisotope production − Ac-225 and Cu-67
NorthStar is poised to be the first commercial-scale supplier of the important therapeutic radioisotopes Ac-225 and Cu-67, both used to directly target and deliver therapeutic doses of radiation to destroy cancer cells in patients with serious disease. Current production technology limitations and resultant limited supply have severely constrained development of these promising therapies.

• NorthStar is applying its commercial-scale radioisotope production expertise to provide reliable Ac-225 and Cu-67 supply to advance clinical research and for commercial radiopharmaceutical products. The Company is leveraging the same technology expertise demonstrated by the successful launch of the RadioGenix System and non-uranium based Mo-99 supply.
• NorthStar has relationships in place with several large pharmaceutical companies to provide clinical trial supply and commercial-scale quantities of Ac-225 and Cu-67. The Company expects to secure long-term supply agreements during 2021.

Specialized SPECT portfolio
NorthStar is actively developing and growing its strategic portfolio of specialized single photon emission computed tomography (SPECT) radiopharmaceuticals to meet increasing clinical needs for SPECT imaging, driven by scientific advancements in cardiology and oncology.

• NorthStar has an exclusive, global licensing agreement with Capella Imaging, Inc. for FibroScint, a novel fibrin-specific diagnostic imaging agent labeled with Tc-99m for SPECT imaging. Pending successful development, FibroScint will have an initial application in the imaging of thrombus (blood clots) associated with left ventricular assist devices (LVADs), and other potential imaging applications in deep vein thrombosis and pulmonary embolism. NorthStar intends to use RadioGenix System-produced Tc-99m in planned clinical studies of FibroScint. Advanced preclinical development is underway, with an exploratory Investigational New Drug (IND) filing for a Phase 1 study planned for early 2022.
• NorthStar is evaluating additional potential opportunities in specialized SPECT radiopharmaceuticals to address unmet healthcare needs and synergies with its product portfolio.

Partnerships and collaborations
NorthStar selectively partners with leading organizations in strategic collaborations designed to augment its portfolio, maximize synergies and drive growth in areas of unmet medical need.

• In June 2020, NorthStar and Monopar Therapeutics Inc. (Nasdaq: MNPR) announced a collaboration to help combat severe COVID-19 and other severe respiratory diseases. The collaboration will couple Monopar’s targeted monoclonal antibody MNPR-101 to a therapeutic radioisotope supplied by NorthStar to create a highly selective agent with potential to spare healthy cells while quickly reducing cytokine storms and their harmful systemic effects. In December 2020, Monopar and NorthStar announced that a clinical candidate was selected, enabling preclinical studies to begin and advancing one step closer to reaching human clinical trials.
• In March 2021, NorthStar and IBA (Ion Beam Applications S.A., EURONEXT) announced a collaboration to increase global availability of Tc-99m, with potential to result in non-uranium Mo-99 being the leading worldwide source of Tc-99m. Worldwide, diagnostic imaging studies using Tc-99m inform healthcare decisions for approximately 30 million patients annually. The collaboration enables companies outside the United States to access Tc-99m Generation Systems (TCM Generation Systems) that utilize NorthStar’s proprietary non-uranium based Mo-99 produced using IBA’s accelerators and beamlines. Early discussions with interested companies are underway.
