ITM and Alpha-9 Oncology Enter Into Supply Agreement for Therapeutic Medical Radioisotope Actinium-225

On April 24, 2025 ITM Isotope Technologies Munich SE (ITM), a leading radiopharmaceutical biotech company, and Alpha-9 Oncology (Alpha-9), a clinical-stage biotechnology company advancing a distinctive portfolio of differentiated and highly targeted radiopharmaceuticals, reported the signing of a supply agreement for Actinium-225 (Ac-225) to support the development of Alpha-9’s radiopharmaceutical programs (Press release, Alpha9 Oncology, APR 24, 2025, View Source [SID1234652095]). Under the terms of the agreement, ITM will supply its therapeutic medical radioisotope, Ac-225, produced by ActineerTM Inc. (Actineer), the joint venture between ITM and Canadian Nuclear Laboratories. Actineer is advancing cutting-edge technologies to secure and expand its supply chain and produce industrial-scale quantities of Ac-225 at rapid speed to meet the growing global demand. Further contract details have not been disclosed.

"This agreement strengthens our ongoing collaboration with Alpha-9 and reaffirms our mission to supply Actinium-225 to companies pioneering novel radiopharmaceuticals for high unmet need cancer indications," said Dr. Andrew Cavey, CEO of ITM. "We deeply value Alpha-9’s continued trust in our capabilities to produce industrial-scale radioisotopes, supporting the development of breakthrough treatments that can potentially improve the lives of patients with cancer worldwide."

Ac-225 is a rare medical radioisotope used in radiopharmaceuticals to treat various cancer indications. It emits high-energy alpha particles with a short penetration range in tissue, enabling precise targeting of tumor cells. Studies with Ac-225 have shown it to cause double-stranded DNA breaks in cancer cells, leading to their destruction[i]. Its unique qualities along with its natural scarcity and manufacturing complexities make Ac-225 a highly sought after resource. With a comparatively short half-life of approximately ten days[ii], Ac-225 requires a highly sophisticated manufacturing and distribution network worldwide.

"With its global strength in providing high-quality radioisotopes including. Lutetium-177 and their growing capabilities for the production of Actinium-225, ITM is a valued partner as we progress our pipeline of clinical and discovery programs to meet the needs of cancer patients," said Alison Fleming Ph.D., COO of Alpha-9 Oncology.

Akoya Biosciences Expands Biopharma Service Portfolio with New ADC Breast Cancer Assay and Real-world IO60 Insights at AACR 2025

On April 24, 2025 Akoya Biosciences, Inc.

New ADC Assay: Advancing Breast Cancer Precision

The emergence of HER2- and TROP2-targeting ADCs—such as those used in the DESTINY, ASCENT, and TROPiCS trials—have transformed breast cancer treatment while introducing greater complexity in therapeutic decision-making. Akoya’s newly launched multiplex immunofluorescence (mIF) panel is designed to address these challenges by enabling more precise patient selection within established breast cancer subtypes.

This ADC-focused panel includes HER2, TROP2, Ki-67, ER/PR, and a proprietary membrane-localization cocktail. It allows for simultaneous quantification of ADC target expression with precise subcellular localization, providing:

Normalized protein expression
Membrane/cytoplasmic expression ratios
Comparative analysis with standard-of-care IHC biomarkers
Now available through Akoya’s Advanced Biopharma Services (ABS), the ADC panel includes comprehensive support—from assay customization to tissue staining, high-resolution imaging, image analysis, and reporting. ABS is purpose-built to accelerate the path from translational discovery to IUO and IVD, with capabilities anchored in:

A CLIA-certified laboratory for clinical-grade assay development
Integrated imaging and analysis workflows for multiplexed biomarker quantification
A clinical trial site and global CRO network for end-to-end study support
The panel is optimized for:

Identifying HER2-low and TROP2-high patients in clinical trial cohorts
Resolving membrane versus cytoplasmic marker expression—critical for ADC efficacy
Delivering consistent, quantitative scoring of each ADC marker
"Multiplexing key targets in context with state-of-the-art membrane resolution is a catalyst for designing precise ADC combination strategies," said Pascal Bamford, Chief Clinical Officer at Akoya. "Our goal is to equip translational and clinical teams with assays that reflect the complexity of the tumor microenvironment while preserving clinical relevance."

Real-World Impact of IO60: Proven in the Field

Originally launched at SITC (Free SITC Whitepaper) 2024, the PhenoCode Discovery IO60 panel remains the fastest ultrahigh-plex spatial proteomics solution for immuno-oncology research. At AACR (Free AACR Whitepaper) 2025, one of Akoya’s customers will present real-world data generated using IO60, showcasing its power in:

Deep immune phenotyping
Tumor microenvironment (TME) profiling
Translating biomarker discovery across oncology pipelines
"Seeing our partners generate impactful insights using IO60 is the strongest validation of our platform’s potential," said Brian McKelligon, Chief Executive Officer of Akoya. "This is how spatial biology becomes translational—by helping researchers get closer to patient-relevant outcomes."

Visit Akoya at AACR (Free AACR Whitepaper) 2025 – Booth #3045

Both innovations—the ADC-focused breast cancer panel and customer-generated data using IO60—will be featured at Booth #3045, where Akoya will highlight the full potential of spatial biology in translational research.
