On December 18, 2025 Niowave Inc., a U.S.- based global leader in medical radioisotope production, reported the expansion of its existing supply agreement with AstraZeneca, a global biopharmaceutical company, to a 10-year commitment to deliver Actinium-225 (Ac-225), following AstraZeneca’s decision to exercise its option to increase capacity. The agreement secures a reliable and scalable supply of this critical isotope to advance AstraZeneca’s growing portfolio of radioconjugates (RCs). RCs are a type of cancer treatment that use radioactive particles to target and destroy cancer cells.

"Our expanded agreement with AstraZeneca underscores Niowave’s central role in scaling high-quality production of medical radioisotopes for the development of targeted cancer treatments," said Mike Zamiara, CEO of Niowave. "We are pleased to play a role in ensuring that AstraZeneca’s promising pipeline of radioconjugates have the isotope supply they need."
Ac-225 is one of the most promising radioisotopes in oncology as its emitted alpha particles deliver highly potent, DNA-damaging energy, enabling precise destruction of tumor cells while limiting harm to surrounding healthy tissue with targeted modalities like RCs. Despite its potential, global supply of Ac-225 remains limited. Niowave’s proprietary superconducting linear accelerator technology and radiochemistry provide sustainable, U.S.-based production to address this need.
As AstraZeneca advances RCs for prostate and other difficult-to-treat cancers, the agreement highlights the critical importance of securing dependable isotope supply.
