• Presentation to highlight positive outcomes of Iomab-B led bone marrow transplant in difficult to treat TP53 patients and the mutation-agnostic mechanism of Actimab-A for patients with relapsed or refractory acute myeloid leukemia
• Iomab-B and Actimab-A represent the only clinical stage antibody radiation conjugates in development for patients with acute myeloid leukemia

NEW YORK, July 25, 2024 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a leader in the development of Antibody Radiation Conjugates (ARCs) and other targeted radiotherapies, today announced that the Company will participate in the 3^rd Annual Targeted Radiopharmaceuticals Summit US, being held in San Diego, CA, from July 30 – August 1, 2024. Actinium's presentation titled, "Overcoming Adverse Cytogenetics, TP53, Other Mutations & Treatment Resistant Disease in Relapsed/Refractory AML Using Antibody Radiation Conjugates," will take place on Wednesday, July 31, 2024^th. The presentation will highlight the following:

• Exploring Iomab-B, a CD45 I-131 ARC, to enable bone marrow transplant (BMT) in otherwise ineligible patients, while Actimab-A, a CD33 Ac-225 ARC, demonstrates strong anti-leukemic activity
  
  
• Outlining responses in heavily pretreated patients for both Iomab-B and Actimab-A, including prior venetoclax treatment or TP53-mutated disease, to demonstrate how targeted radiotherapies offer broad therapeutic potential as backbone regimens
  
  
• Revealing preclinical data to further show the benefits of combining Actimab-A with targeted therapies, such as FLT3 inhibitors, to enhance anti-tumor response

About Actinium Pharmaceuticals, Inc.

Actinium develops targeted radiotherapies to meaningfully improve survival for people who have failed existing oncology therapies. Advanced pipeline candidates Iomab-B (pre-BLA & MAA (EU)), an induction and conditioning agent prior to bone marrow transplant, and Actimab-A (Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute), a therapeutic agent, have demonstrated potential to extend survival outcomes for people with relapsed and refractory acute myeloid leukemia. Actinium plans to advance Iomab-B for other blood cancers and next generation conditioning candidate Iomab-ACT to improve cell and gene therapy outcomes. Actinium holds more than 230 patents and patent applications including several patents related to the manufacture of the isotope Ac-225 in a cyclotron.
