Bruce Power and IsoGen set first critical milestone for exclusive irradiation service provided to ITM for its production of no-carrier-added Lutetium-177

Validation, testing and training will start on a mock-up isotope production system in fall 2020

ITM Medical Isotopes GmbH, a subsidiary of the biotechnology and radiopharmaceutical group of companies ITM Isotopen Technologien München AG (ITM), announced today that Bruce Power, an electricity company, and IsoGen, a joint venture between the two nuclear energy companies Framatome and Kinectrics, have set the first critical milestone for a reliable and consistent irradiation service which will be provided to ITM exclusively for 15 years. Thereby a dedicated mock-up of the isotope production system was developed for validation, testing and training which will start in fall 2020.

The medical radioisotope Lutetium-177 (177Lu) will be obtained by irradiating Ytterbium-176 at the Bruce Power Reactors, as contractually stipulated in an exclusive agreement between Bruce Power, IsoGen and ITM Medical Isotopes GmbH. Bruce Power Reactors are uniquely positioned to fulfil the necessary requirements to reach ITM’s high standards validated in a successful feasibility study September last year. The construction of the isotope production system at Bruce Power by IsoGen is currently planned to start in January 2021 once the mock-up has been fully tested. The mock-up is currently in the final phase of engineering, evaluation, and design and will allow validation and training before deploying the isotope production system to Bruce Power’s units.

The intermediate material to be generated at Bruce Power over 15 years will be processed by ITM via its unique manufacturing methodology to the highly pure form of 177Lu, no-carrier-added (n.c.a.) 177Lu (EndolucinBeta®), at ITM´s global network of radiopharmaceutical production facilities. N.c.a. 177Lu is supplied by ITM to clinics worldwide and is used as a therapeutic radiopharmaceutical precursor for Targeted Radionuclide Therapy of cancers such as neuroendocrine tumors, prostate cancer, Non-Hodgkin’s lymphoma, bone metastases and several further indications.

Steffen Schuster, CEO of ITM commented: “Seeing the great progress in the development of the isotope production system by Bruce Power and IsoGen, we are confident that this partnership secures another high-quality source of Lutetium-177 for ITM which further increases scalability of our production ensuring a steady supply of n.c.a. Lutetium-177 on a global scale. Our clinical and industry partner’s demand for the radiopharmaceutical precursor no-carrier-added Lutetium-177 is constantly growing and as a company we are dedicated to providing our highly pure radioisotope for Targeted Radionuclide Therapy to cancer patients worldwide.”

About n.c.a. Lutetium-177 / EndolucinBeta®

EndolucinBeta®, no carrier-added (n.c.a.) Lutetium-177 (177Lu) chloride, is a radiopharmaceutical precursor used in Targeted Radionuclide Therapy for the treatment of various diseases, like cancer. When labeled with a disease-specific carrier molecule (e.g. peptide or antibody), the targeted radiopharmaceutical binds to a tumor specific receptor, according to the lock and key principle. EndolucinBeta® has a half-life of 6.647 days. No-carrier-added Lutetium-177 provides the highest specific activity of more than 3,000 GBq/mg at Activity Reference Time (ART), whereas the day of calibration can be flexibly selected by the customer. Optimal preconditions for efficient radiolabeling of biomolecules over its entire shelf-life of 9 days after production are ensured. EndolucinBeta® exhibits an extraordinary level of radionuclidic purity. EndolucinBeta® does not contain metastable Lutetium-177m. Thus, there is no need for cost intensive clinical disposal management and EndolucinBeta® can therefore be used globally – also in regions facing strict radiation protection regulations.
