IsoTherapeutics Group, LLC (IsoTherapeutics) is a privately held, commercial-stage radiopharmaceutical company that provides radiochemistry and bioconjugation development and contract manufacturing services. It specializes in developing novel therapeutic and diagnostic agents for severe diseases. The company's scientists have received over 100 patents for their work in chemistry and radiopharmaceutical formulations.
IsoTherapeutics enhances Telix Pharmaceuticals' in-house development capabilities and expands its US manufacturing footprint, particularly in bioconjugation and isotope processing. It has a GMP clean room and production infrastructure suitable for clinical use, with extensive capacity to process various therapeutic isotopes used in Telix's development portfolio.
In April 2024, Telix Pharmaceuticals completed the acquisition of IsoTherapeutics for a total consideration of up to USUSD 13.6 million, comprising an upfront payment and performance-related milestone payments. The acquisition aligns with Telix's strategy of vertical integration, enabling it to innovate and scale up manufacturing while gaining greater control over the isotope supply chain to support the commercialization of its investigational therapeutic assets.

Avid Radiopharmaceuticals, a subsidiary of Eli Lilly, developed the first radioactive diagnostic agent approved by the US Food and Drug Administration (FDA) for imaging tau neurofibrillary tangles on positron emission tomography (PET) scans. The F-18 flortaucipir tracer, marketed under the name Tauvid, helps clinicians estimate the density and distribution of tau tangles in the brains of adults with cognitive impairment being evaluated for Alzheimer's disease.
Tauvid works by binding to tau proteins that form neurofibrillary tangles, which are a hallmark of Alzheimer's disease along with amyloid plaques. Previously, doctors could only diagnose Alzheimer's neuropathologically by identifying both plaques and tangles in the brain after death. With Tauvid, physicians can now visualize and assess tau pathology in living patients through PET imaging.
The FDA's approval of Tauvid in May 2020 was supported by two clinical studies evaluating the agent's safety and effectiveness. These studies demonstrated that readers interpreting Tauvid PET scans had a high probability of accurately detecting tau pathology and an average-to-high probability of correctly identifying patients without tau pathology.

Alpha Source is a company that manufactures and supplies alpha radiation sources, primarily composite alpha sources containing Pu-239, Am-241, and Cm-244 radionuclides electroplated onto platinum or platinum-clad nickel foils. These sources are designed for alpha spectroscopy systems, providing alpha particles in the energy range of approximately 5100 to 5800 keV with line widths typically less than 20 keV FWHM. This wide energy range allows for valid energy calibration of most alpha-emitting nuclides. Alpha Source offers its composite alpha sources in three configurations: A-1, A-2, and PM. The sources are uncovered and have an active area of 5.0 mm. When purchased as NIST traceable standards, the sources can also be used to determine detector efficiencies for alpha particles, with total and individual activities provided on the Certificate of Calibration.
In addition to its core alpha source product line, Alpha Source also provides nationwide service for extending the life of ultrasound imaging equipment through preventative maintenance and quality replacement parts. The company offers high-quality replacement parts for biomedical equipment, along with value-added services to streamline supply chain operations.
Alpha Source has over 30 years of expertise in manufacturing and sourcing high-quality medical replacement battery packs, offering solutions that optimize battery life and costs for healthcare facilities.

Ionetix is a cyclotron technology and isotope manufacturing company based in the US. It developed the world's first commercial compact superconducting cyclotron, the ION-12SC, which is used to produce N-13 Ammonia, a highly accurate Positron Emission Tomography (PET) imaging agent for detecting Coronary Artery Disease (CAD). The company's proprietary cyclotron technology platform enables access to scarce radioisotopes used for diagnostic and therapeutic radiopharmaceuticals.
Ionetix's cyclotrons can produce high-purity alpha-emitting radionuclides like Actinium-225 (Ac-225) and Astatine-211 (At-211), which are utilized in targeted alpha therapies for cancer treatment. In April 2023, the company successfully produced Astatine-211 at its new Alpha Isotope Manufacturing facility in Lansing, Michigan, using a 30 MeV cyclotron. This facility is dedicated exclusively to producing alpha-emitting radionuclides via cyclotrons. In June 2024, Ionetix announced the successful production of Actinium-225, marking a pivotal milestone as the first commercial cyclotron-produced Ac-225.
Ionetix's business model involves establishing a network of ION-12SC cyclotrons installed on or near the campuses of PET programs across the US. The company covers the costs related to installation and operation, making N-13 Ammonia available to providers through a pay-by-the-dose model, ensuring accessibility and affordability. Ionetix also provides N-13, F-18, and Ga-68 for diagnostic imaging. Its distribution supply chain includes contract drug manufacturing and "white glove" distribution logistics, enabling global access to these imaging agents and targeted radiotherapies.

Therapeia GmbH & Co. KG is a German specialist company focused on developing diagnostic and therapeutic radiopharmaceuticals to address unmet patient needs. Their lead product candidate, ACD-101, is a family of products for the diagnosis and treatment of malignant glioma (brain cancer). ACD-101 combines several anti-cancer effects within a single molecule, including cytostatic properties, an intrinsic radio-sensitizer effect that enhances the efficacy of external radiation therapy (the current standard treatment), and the ability to be radiolabeled with 131I for intracellular 131I-irradiation ("endo-radiotherapy"), similar to radioiodine therapy used for thyroid cancer.
ACD-101 is actively transported across the intact blood-brain barrier and accumulates in tumor tissue, where it is retained for up to a week. This intratumor accumulation occurs independently of histological tumor type in both low and high-grade gliomas (WHO grades II-IV), allowing for universal therapeutic use regardless of glioma histology. In a rat model, experimental human gliomas were curatively treated for the first time using 131I-ACD-101. This endo-radiotherapy can be combined with conventional external radiotherapy to maximize synergies of different anti-tumor modes of action.
