NorthStar anticipates sustained progress and growth as we expand our horizons globally and execute strongly in our mission to provide reliable radioisotope supply to support patients’ healthcare needs."

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.
About the RadioGenix System (Technetium Tc 99m Generator)
The RadioGenix System is an innovative, high tech separation platform that is approved for processing non-uranium based molybdenum-99 (Mo-99) for the production of the important medical radioisotope, technetium-99m (Tc-99m). Prior to availability of RadioGenix technology, the U.S. supply chain for Mo-99 has been subject to frequent and sometimes severe interruptions which negatively impact patient healthcare. Approved by the U.S. Food and Drug Administration (FDA) in 2018, the RadioGenix System is the first and only on-site, automated isotope separation system of its kind for use with non-uranium based Mo-99, designed to help alleviate shortage situations and expand domestic supply.

Recently, Lindis Biotech, partner of LintonPharm, initiated a dose-finding Phase 1 trial with catumaxomab in NMIBC patients in Germany (clinicaltrials.gov: NCT04819399) and reported an excellent safety profile, which supports the conduct of the Phase 1/2 trial in China.

"Regulatory clearance to move forward with our clinical program evaluating catumaxomab in bladder cancer is another significant milestone for LintonPharm and supports our goal of exploring the potential for this targeted therapy in a broad range of cancers," said Robert Li, Ph.D., DABT, Co-founder and CEO of LintonPharm. "Patients with NMIBC BCG failure have high rates of tumor recurrence and often face a lifetime of surgical intervention which may impact bladder function. New treatment options are needed and we are hopeful that this study puts us one step closer toward helping these patients."

Bladder cancer is the 10th most common cancer worldwide. In 2020, bladder cancer was diagnosed in approximately 573,278 patients globally and approximately 1.8 million people were living with this form of cancer over a five-year period [1]. NMIBC is a cancer found in the tissue that lines the inner surface of the bladder and accounts for approximately 75 percent of all bladder cancer [2]. Transurethral resection of bladder tumor (TURBT) is the current standard of treatment for NMIBC. Relapse is common after TURBT (up to 70 percent at five years) and as a result, patients often undergo multiple surgical procedures over a longer period [2]. Intravesical BCG is commonly used as an adjuvant treatment after TURBT. However, a large number of patients experience tumor recurrence, which is referred to as BCG failure [3]. Radical cystectomy (RC) is usually recommended after BCG failure, but many physicians and patients refrain from RC in favor of preserving bladder function.

About Catumaxomab

Catumaxomab was approved by the European Medicines Agency in 2009 for the treatment of malignant ascites. This bispecific antibody binds to a transmembrane glycoprotein on the tumor cell–the epithelial cell adhesion molecule (EpCAM)–and CD3 on the T cell, and also recruits immune accessory cells through FcγR binding. Catumaxomab destroys tumor cells by engaging T cell and accessory cell mediated cytotoxicity and has the potential to induce long-term vaccinal effects which has been verified in animal models.

Recently, catumaxomab was authorized by regulatory authorities in China, Taiwan (China) and South Korea to conduct a global Phase 3 clinical trial for treating patients with advanced gastric cancer.

The article, titled "Long-term outcomes in a multicenter, prospective cohort evaluating the prognostic 31-gene expression profile for cutaneous melanoma," was published in the peer-reviewed journal, JCO Precision Oncology.

Study background:

The study’s key objective was to demonstrate the prognostic value of DecisionDx-Melanoma with long-term follow-up that extends the assessment time period for a previously studied cohort. The study achieved its primary objective and expanded upon prior results to show the ability of the test to accurately identifying recurrence risk of patients with American Joint Committee on Cancer (AJCC) 8th Edition staging system early stage I-IIA disease.

Study results:

Consistent with previous prospective validation and performance studies, the DecisionDx-Melanoma test was significantly associated with the outcomes of recurrence-free (RFS), distant metastasis-free (DMFS) and overall survival (OS) in univariate analysis of patients diagnosed with stage I-III melanoma. The test’s result was also a significant, independent predictor of the same endpoints when compared to AJCC staging in multivariable analysis. Additionally, study authors conclude that combining DecisionDx-Melanoma test results with AJCC staging enhances sensitivity and negative predictive value over each approach alone, identifying those who may benefit from more or less intense follow-up. Further, accurate risk stratification by the DecisionDx-Melanoma test was demonstrated in the cohort of patients with stage I-IIA melanoma, a group that is currently recommended to receive low-intensity management but that contributes substantially to the number of patients who die from melanoma each year.

"The most impactful measures of appropriate melanoma management include survival time and the quality of that time post-diagnosis," said first author Eddy Hsueh, M.D., surgical oncologist at St. Louis University, St. Louis, MO. "In this study, we demonstrated that DecisionDx-Melanoma results are significant predictors of real-world recurrence and metastasis rates, which suggests that the test can provide clinically actionable information when making cancer management decisions in early-stage melanoma."

About DecisionDx-Melanoma

DecisionDx-Melanoma is a gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of cutaneous melanoma metastasis or recurrence, as well as sentinel lymph node positivity, independent of traditional staging factors, and has been studied in more than 5,700 patient samples. Using tissue from the primary melanoma, the test measures the expression of 31 genes. The test has been validated in four archival risk of recurrence studies of 901 patients and six prospective risk of recurrence studies including more than 1,600 patients. To predict likelihood of sentinel lymph node positivity, the Company utilizes its proprietary algorithm, i31-GEP, to produce an integrated test result. i31-GEP is an artificial intelligence-based neural network algorithm (independently validated in a cohort of 1,674 prospective, consecutively tested patients with T1-T4 cutaneous melanoma) that integrates the DecisionDx-Melanoma test result with the patient’s traditional clinicopathologic features. Impact on patient management plans for one of every two patients tested has been demonstrated in four multicenter and single-center studies including more than 560 patients. The consistent performance and accuracy demonstrated in these studies provides confidence in disease management plans that incorporate DecisionDx-Melanoma test results. Through December 31, 2020, DecisionDx-Melanoma has been ordered more than 68,920 times for use in patients with cutaneous melanoma.

Genetron Health Releases 22 New Research Results at American Association for Cancer Research Annual Meeting (AACR) 2021

On April 13, 2021 Genetron Holdings Limited ("Genetron Health" or the "Company", NASDAQ:GTH), a leading precision oncology platform company in China that specializes in molecular profiling tests, early cancer screening products and companion diagnostics development, reported the release of 22 research results at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2021 (AACR 2021) (Press release, Genetron Health Technologies, APR 13, 2021, View Source [SID1234577985]).

The results were from a series of studies that Genetron Health conducted with 13 leading hospitals in China. The Company leveraged original research and innovative technologies such as integrated DNA and RNA sequencing in gene fusion detection, a new MSI (microsatellite instability) detection algorithm model, its "One-Step Seq" method, and core products such as Onco Panscan and comprehensive sarcoma gene detection tests.

These studies analyzed the spread of various types of cancers throughout the Chinese population, covering lung cancer, intestinal cancer, pancreatic cancer, nervous system tumors, thymic carcinoma, and other types of cancers. More specifically, the studies focused on these cancers’ inheritance, mutation, and fusion characteristics. They paid particular attention to the validity of immunotherapy markers for various types of cancers, as well as rare cancer cases and new therapeutic treatments. These studies provided important insights that can enable the accurate diagnosis and treatment of cancer, facilitating the design of effective products in the future.

Dr. Yunfu Hu, Genetron Health’s Chief Medical Officer, said, "Genetron Health is committed to building a strong bridge between scientific research and clinical applications. The studies’ results show that the Company’s innovative technologies and products can help to further analyze the characteristics of cancer genomics for different types of cancer, optimize conventional technologies, and provide ideas for new product design, so as to promote the healthy development of translational medicine. For example, for soft tissue sarcoma (STS), the use of integrated DNA and RNA sequencing in gene fusion detection can greatly improve the detection rate of STS gene fusion, which may benefit more STS patients.

"For hereditary cancers, the screening method used to detect Li-Fraumeni syndrome will also improve cancer detection rates in these patients and provide more intervention opportunities for them; for colorectal cancer, our analysis of KMT2C/2D inactivation mutations is also pointing to more possibilities for immunotherapy patients. And lastly, our work on rare cancer cases and the experimentation of new treatments is furthering the development of diagnosis and treatment research for these various types of patients," Hu added.

Exploring Ways to Optimize Conventional Technologies

To overcome the DNA-sequencing limitations involved with detecting gene fusion, Genetron Health optimized the use of conventional technologies in Study #2288. During this study, more accurate, efficient, and low-cost detection of gene fusion mutations was achieved at the RNA sequencing level. This was evaluated and verified in a STS cohort of 142 Chinese patients. Compared with DNA detection alone, integrated DNA and RNA sequencing improved the detection rate of STS fusion by 177%, which could provide clinical benefits for more STS patients.

Study #2080 optimized the algorithm that detects MSI through next generation sequencing (NGS). The study was conducted on a large cohort of 2,523 samples with various types of cancers. According to the study results, the optimized algorithm was 99.9% consistent with PCR (polymerase chain reaction) testing – the industry’s current gold standard. The positive predictive value of MSI-H was 98.73%, and the negative predictive value of MSS was 99.92%.

Focusing on Hereditary Cancers

Two studies (#1464, #2557) provided screening methods for Li-Fraumeni syndrome, an inherited condition that is characterized by an increased risk for certain types of cancer. These methods utilized in-depth analysis of germline mutations and investigated the distribution of genetic characteristics for pancreatic cancer in the Chinese population, providing evidence and additional ideas for the diagnosis and treatment of hereditary cancers.

Investigating Gene Mutation and Fusion Characteristics

Nine studies (#2217, #2163, #2223, #2216, #2215, #2313, #2252, #2183, #2182) examined the mutation and fusion characteristics of soft tissue sarcoma, melanoma, neuroendocrine tumors, non-small cell lung cancer, thymic carcinoma, small bowel adenocarcinoma, ampullary carcinoma, etc. The studies focused on finding potential targets for precise therapeutic treatment, drug-resistant targets and effective countermeasures.

Probing Immunotherapy Markers

Four studies (#1639, #1640, #1641, #1681) investigated the predictive effects of KMT2C/D loss-of-function mutations, DDR signaling pathway-related gene mutations, ARID1A mutations, and BRCA1/2 mutations on immunotherapy treatments for a wide range of cancer types, providing further insights.

Spotlight on Rare Cancer Cases and New Treatment Therapies

Five studies (#0803, #0422, #1209, #1199, #0625) detected special molecular abnormalities in patients with Lynch syndrome-related lung cancer, metastatic melanoma, anaplastic thyroid carcinoma, papillary thyroid carcinoma and liposarcoma, respectively. In these studies, scientists used molecular detection to diagnose and classify such cancers, and new, targeted therapy and immunotherapy schemes were adopted for these patients, benefiting them in the long run.
