NorthStar Medical Radioisotopes, LLC, a global innovator in the development, production and commercialization of radiopharmaceuticals used for therapeutic applications and medical imaging, and Nucleus RadioPharma, a full-service Contract Development and Manufacturing Organization (CDMO) dedicated to building robust and reliable clinical and commercial supply chains for targeted radiotherapies, today announced the signing of a supply agreement for the therapeutic radioisotope actinium-225 (Ac-225). Under terms of the agreement, NorthStar will supply its high purity, non-carrier added (n.c.a.) Ac-225 to Nucleus. Nucleus will use NorthStar’s Ac-225 for their customers’ radioligand pharmaceutical programs.
Ac-225 is a high energy alpha-emitting radioisotope of increasing interest for clinical studies investigating the use of targeted radiopharmaceutical therapy, which combines select molecules with therapeutic radioisotopes to directly target and deliver therapeutic doses of radiation to destroy cancer cells in patients with serious disease. Ac-225 carries sufficient radiation to cause cell death in a localized area of targeted cells, while its half-life limits unwanted radioactivity in patients. Clinical research and commercial use of Ac-225 have been constrained by chronic short supply due to limitations of current production technology. NorthStar is positioned to be the first commercial-scale producer of n.c.a. Ac-225 and copper-67 (Cu-67) for advancing clinical research and commercial radiopharmaceutical therapy products. The Company will use its electron accelerator technology to produce n.c.a. Ac-225 that is free of long-lived radioactive contaminants and byproducts associated with other production methods. Such contaminants pose regulatory and waste management challenges for pharmaceutical companies, hospitals, and health systems.
