Telix Expands U.S. Development and Manufacturing Infrastructure with Acquisition of IsoTherapeutics

Melbourne (Australia) – 27 February 2024. Telix Pharmaceuticals Limited (ASX: TLX, Telix, the Company) today announces it has entered into an agreement to acquire IsoTherapeutics Group, LLC (IsoTherapeutics), a specialty radiopharmaceutical development and bioconjugation firm, based in Angleton, Texas. Founded in 2005, IsoTherapeutics is a privately held, commercial-stage company, which provides radiochemistry and bioconjugation development and contract manufacturing services to many companies in the radiopharmaceutical industry, including Telix.
In line with Telix’s continued investment in the vertical integration of supply chain, manufacturing and development capabilities, the acquisition is expected to further enhance Telix’s in-house drug development capabilities. A key driver for the acquisition is to enable Telix to bring select aspects of its development programs in-house, with the goal of reducing cost and time to achieve technical milestones.
The acquisition will also expand Telix’s U.S. manufacturing footprint with a site that includes a GMP1 clean room and production infrastructure suitable for clinical use. The site also has extensive capacity to process a wide variety of therapeutic isotopes used in Telix’s development portfolio.
