March 3, 2021  NorthStar Medical Radioisotopes Advances Focus on Therapeutic and Specialized SPECT Radiopharmaceuticals

​

BELOIT, Wis., March 3, 2021 – NorthStar Medical Radioisotopes, LLC, a global innovator in the development, production and commercialization of radiopharmaceuticals used for medical imaging and therapeutic applications, today announced organizational changes to drive focused growth for its therapeutic and specialized single photon emission computed tomography (SPECT) radioisotopes business. The new structure enables NorthStar to advance its efforts in radioisotope development and commercialization planning in parallel with its ongoing expansion programs for increased U.S. molybdenum-99 (Mo-99) capacity and production.

​

In conjunction with other organizational changes, NorthStar has appointed Dave Wilson, RPh., BCNP, as Vice President, Advanced Radiopharmaceutical and Therapeutic Technologies. He will have responsibility to advance NorthStar’s Copper-67 (Cu-67), Actinium-225 (Ac-225) and FibroScint programs to commercialization. Mr. Wilson, a five-year veteran at NorthStar, was previously Vice President, Commercial Operations for the Company, and has more than 25 years of experience in cGMP radiopharmaceutical manufacturing and radiopharmaceutical operations.

​

NorthStar is poised to be the first commercial-scale supplier of the important therapeutic radioisotopes Cu-67 and Ac-225, used in nuclear medicine to directly target and deliver therapeutic doses of radiation to destroy cancer cells in patients with serious disease. Development of promising therapies has been severely constrained by current production technology limitations and resultant limited supply. NorthStar is applying its commercial-scale radioisotope production technology expertise to provide reliable Cu-67 and Ac-225 supply for use in advancing clinical research and for commercial radiopharmaceutical products. The Company has agreements in place with several large pharmaceutical companies to provide clinical trial supply and commercial-scale quantities of Cu-67 and Ac-225.

​

NorthStar is also actively developing and growing its strategic portfolio of specialized 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 the radioisotope technetium-99m (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). Other potential imaging applications include deep vein thrombosis and pulmonary embolism. Preclinical development of FibroScint is well underway, with an exploratory Investigational New Drug filing planned for later in 2021.

​

“NorthStar is now optimally positioned for continued growth and success in developing and delivering on our portfolio of medical radioisotopes to meet the needs of patients and advance clinical research,” said Stephen Merrick, President and Chief Executive Officer of NorthStar Medical Radioisotopes. “With a dedicated focus to developing commercial-scale production technologies for Cu-67 and Ac-225 radioisotopes, we can bring much-needed therapies to patients and researchers. The proven expertise and innovative approach as demonstrated in the successful development and commercialization of U.S.-produced, non-uranium based Mo-99 and the RadioGenix® System (technetium Tc-99 generator) will be brought to our therapeutic radioisotope programs.”

​

Mr. Merrick continued, “We are also evaluating additional potential opportunities in specialized SPECT radiopharmaceuticals, with an eye to addressing unmet healthcare needs and synergies with our product portfolio. FibroScint has the potential to inform the management of multiple serious cardiovascular conditions, and complements the RadioGenix System in that we intend to use RadioGenix System-produced Tc-99m as we advance the compound into clinical studies.”

​

NorthStar is the only commercial producer of Mo-99 in the United States, having provided more than two years of stable U.S. production to date, and continues ongoing activities to expand U.S.-Mo-99 capacity and production. The Company is nearing completion of its Accelerator Production facility in Beloit, Wisconsin. This will ensure continued domestic Mo-99 supply for the United States through dual production and processing hubs for additional capacity and scheduling flexibility. The expansion of this facility will augment current processing in Columbia, Missouri to continue joint production of Mo-99 in partnership with the University of Missouri Research Reactor (MURR®).

March 3, 2020  Capella Imaging and Northstar Medical Imaging anounce their partnership.

BELOIT, Wis. – March 3, 2020 – NorthStar Medical Technologies, LLC, a global innovator in the production and distribution of radioisotopes used for medical imaging, today announced that it has entered into a worldwide, exclusive licensing agreement with Capella Imaging, LLC, a BioGenerator company focused on the development of diagnostic imaging agents to support unmet medical needs. Under the agreement, NorthStar has licensed exclusive rights to a fibrin-targeted diagnostic imaging agent for cardiac imaging. FibroScint (Tc-99m F4A) is a fibrin-targeted, peptide compound labeled with the radioisotope technetium-99m (Tc-99m) for SPECT imaging. If successfully developed and approved, it may have potential applications across multiple cardiovascular conditions such as thrombus (blood clots) associated with left ventricular assist devices (LVADs), deep vein thrombosis, pulmonary embolism and acute coronary syndrome. Initial clinical investigation of FibroScint will be an exploratory Phase 1 study for its potential use in identifying thrombus in patients with serious heart failure who use an LVAD. It is anticipated that the first indication for FibroScint will receive an Orphan Drug designation.

​

“This agreement aligns with NorthStar’s strategic focus and further advances our mission to develop and commercialize radioisotope products to meet the needs of patients and advance clinical research,” said Stephen Merrick, President and Chief Executive Officer of NorthStar Medical Technologies. “FibroScint is a unique diagnostic agent and an ideal addition to our portfolio which complements the commercially available RadioGenix® System (technetium Tc 99m generator). NorthStar intends to use Tc-99m produced by RadioGenix Systems in the planned clinical studies of FibroScint. We look forward to collaborating with Capella Imaging on further early development of this agent.”

​

Under terms of the agreement, NorthStar will invest $1 million in Capella equity in conjunction with Capella seeking federal funding grants, both of which will be used for completion of Phase 1 clinical development through an exploratory Investigational New Drug application (eIND) for the LVAD indication. NorthStar has the option to make additional equity investment in support of future clinical trials and would make additional success payments to Capella contingent upon completion of certain regulatory and revenue milestones, with royalties payable upon commercialization of the product in each of three potential diagnostic indications. Further terms of the agreement were not disclosed.

​

“Options for patients with severe heart failure are limited to heart transplantation, LVADs or hospice care,” said James T. Harvey, PhD, Senior Vice President and Chief Science Officer of NorthStar. “While LVADs significantly improve a patient’s survival and quality of life, they are also associated with complications such as thromboembolic events and gastrointestinal bleeding, and anticoagulation therapies may further exacerbate these bleeding events. There is a need for diagnostic imaging tools that can inform clinical management and monitoring of heart failure patients using LVADs, with the aim of reducing some of these complications, and NorthStar plans to investigate FibroScint to help meet this need.”

​

“We are pleased to enter into this license agreement with NorthStar Medical Technologies, and we believe that the company’s proven experience in the development and commercialization of innovative technologies will be useful in advancing further development of FibroScint,” said James Blackledge, PhD, President, Capella Imaging. “Fibroscint has shown potential in numerous indications, and preclinical studies have been encouraging and merit formal clinical assessment through an exploratory Phase 1 study.”

​

About FibroScint (Tc-99m F4A)
FibroScint (Tc-99m F4A] consists of a fibrin-targeted, peptide compound labeled with the radioisotope technetium-99m (Tc-99m) for SPECT imaging. It was invented by researchers at the Washington University School of Medicine, St. Louis, Mo., and exclusively licensed by NorthStar Medical Technologies in 2020. If successfully developed and approved, FibroScint may have potential applications across multiple cardiovascular conditions such as thrombi (blood clots) associated with left ventricular assist devices (LVADs), deep vein thrombosis, pulmonary embolism and acute coronary syndrome. NorthStar is initially investigating FibroScint in a planned exploratory Phase 1 study for use in identifying thrombus in patients with serious heart failure who use a left ventricular assist device (LVAD). FibroScint has not received regulatory approval.

​

About Heart Failure and Left Ventricular Assist Devices (LVADs)
Heart failure affects an estimated 6.2 million Americans annually and its incidence continues to grow. More than 80,000 patients die of severe heart failure per year in the United States, yet only 2,500 – 3,000 donor hearts become available. Options for patients with severe heart failure include heart transplantation, mechanical circulatory support such as a left ventricular assist device (LVAD) or hospice care. LVADs significantly improve survival and quality of life. However, they are associated with complications such as thromboembolic events, gastrointestinal bleeding and infection, and despite the use of anticoagulation therapies, LVAD-associated thrombi develop over time. Current diagnostic imaging techniques are limited in their ability to detect thrombus in the high flow conditions and anticoagulated environment of LVADs.
