RadioMedix and Thor Medical enter supply agreement for thorium-228

OSLO, Norway and HOUSTON, Dec. 04, 2025 (GLOBE NEWSWIRE) — Thor Medical ASA, a leading emerging supplier of alpha-emitters for next-generation precision cancer treatment, and RadioMedix, Inc., a U.S. based clinical-stage biotechnology company focused on innovative targeted radiopharmaceuticals for diagnosis, monitoring and cancer therapy, have entered into a five-year frame agreement for the supply of thorium-228 (Th-228). The supply of Th-228 will start in 2026, with volumes scaling with increased production at Thor Medical’s AlphaOne.

RadioMedix will use the Th-228 supplied by Thor Medical as a precursor for the manufacturing of lead-212 (Pb-212) in its development pipeline, and to leverage the company’s RAHA-100 Pb-212 generator, designed to increase the availability of Pb-212 for the rapidly growing radiopharmaceutical industry.

“Targeted alpha therapies hold great medical and commercial potential, and the leading players see the importance of securing scalable supply of alpha-emitters to maintain the strong momentum. The partnership with RadioMedix reflects our ambition to be a preferred supplier to the innovators leading the development of these more targeted and effective cancer treatments,” says Jasper Kurth, CEO of Thor Medical.

“This partnership and the reliable supply of Th-228 marks an important step for the nuclear medicine field as we work to unlock the full potential of our RAHA-100 bench-top generator to expand clinical-grade Pb-212 production for radiopharmaceutical research and development. Reliable access to this critical isotope strengthens our pipeline in radiopharmaceutical drug development and helps accelerate the advancement of targeted alpha therapies with the potential to improve patient outcomes,” said Ebrahim S. Delpassand, M.D., Chief Executive Officer of RadioMedix.

The agreement with RadioMedix adds to Thor Medical’s growing portfolio of Th-228 supply agreements with leading radiopharmaceutical companies, globally.
