- Patent Protection Expansion: Actinium Pharmaceuticals has secured two patent allowances in Canada for its Actimab-A and Iomab-ACT programs, enhancing its intellectual property protection in hematologic malignancies and gene-edited cell therapies, reflecting the company's strategic positioning in global markets.
- Market Significance: This allowance not only complements existing protections in Japan and the U.S. but also establishes a foundation for growth in Canada, expected to bolster its competitive edge within a global patent estate of approximately 250 patents.
- Therapeutic Innovation: The patent for Actimab-A covers its use in combination with the CLAG-M chemotherapy regimen, anticipated to serve as a key therapeutic backbone for acute myeloid leukemia (AML) treatment, with a patent term extending to 2039, indicating long-term market potential.
- Cell Therapy Preparation: The Iomab-ACT patent focuses on preparing patients for gene-edited cell therapies, expected to drive innovation in the cell therapy space, with a patent term lasting until 2038, further solidifying its position in emerging treatment methodologies.

About ATNM
Actinium Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company pioneering the development of targeted radiotherapies to address significant unmet medical needs in oncology. It operates a pipeline of both early and later stage development programs with two novel solid tumor product candidates, ATNM-400 and Actimab-A, with pan-tumor potential; Actimab-A, which is also being developed as a therapeutic backbone for acute myeloid leukemia and myelodysplastic syndrome in partnership with the National Cancer Institute (NCI), and two targeted conditioning agents, Iomab-B for bone marrow transplant and Iomab-ACT for cell & gene therapies. Its solid tumor asset, ATNM-400, targets a novel antigen distinct from PSMA, with demonstrated preclinical activity across metastatic castration-resistant prostate cancer (mCRPC), non-small cell lung cancer (NSCLC), and breast cancer. Its hematology franchise includes Actimab-A, Iomab-B and Iomab-ACT, which are CD45-targeting conditioning agents.

ATNM-400 Demonstrates Potent Efficacy in Prostate Cancer
- Efficacy Breakthrough: ATNM-400 maintains potent activity against prostate cancer cells and tumors resistant to all three approved ARPIs, achieving a 94% tumor growth inhibition rate, significantly outperforming apalutamide and darolutamide, indicating its potential as both a monotherapy and in combination treatments.
- Safety Advantages: ATNM-400 demonstrates a consistent safety profile across both single and repeat dosing regimens with minimal off-target toxicity, showcasing good dosing flexibility and a wide therapeutic window that could mitigate clinical translation risks.
- Market Opportunity: With approximately 50,000 patients exhausting ARPI therapy annually, ATNM-400's unique mechanism positions it to address a broad patient population, from those who have failed ARPIs to PSMA-low and PSMA-negative patients, potentially serving over 100,000 patients each year.
- Preclinical Research Support: In low-PSMA expressing tumor models, ATNM-400's single bolus dosing shows superior tumor control compared to 177Lu-PSMA-617, and its target not being expressed in salivary glands suggests it will not cause xerostomia, making it a more attractive treatment option.
