Analyst Ratings

HC Wainwright & Co. Reiterates Buy on Actinium Pharma, Maintains $4 Price Target

-&nbsp; ATNM-400 shows; superior prostate cancer cell killing compared to androgen receptor inhibitor Xtandi&#xAE; (enzalutamide), the ability to overcome Xtandi resistance, and activity in combination
-&nbsp; ATNM-400 is more efficacious than both Pluvicto&#xAE; (177-Lu-PSMA-617) and Ac-225-PSMA-617 targeted radiotherapy in prostate cancer in vitro and in vivo models and overcome resistance in prostate cancer tumors that failed Pluvicto&#xAE; therapy
-&nbsp; ATNM-400's target is highly differentiated from PSMA as it is implicated in disease biology, contributing to disease progression, faster progression to castration resistance and poorer survival outcomes with target expression reported following androgen receptor inhibitor and PSMA radiotherapy
-&nbsp; Data further supports ATNM-400's potential to address critical gaps in prostate cancer treatment as a monotherapy or in sequence with other therapeutic modalities
NEW YORK, June 23, 2025 /PRNewswire/ -- Actinium Pharmaceuticals, Inc.&nbsp;(NYSE:<a class="ticker" href="https://www.benzinga.com/stock/ATNM#NYSE">ATNM</a>) (Actinium or the Company), a pioneer in the development of targeted radiotherapies, today reported new preclinical data from its first-in-class, non-PSMA targeting radiotherapy prostate cancer candidate ATNM-400, that leverages the potent alpha-particle emitter Actinium-225 (Ac-225) isotope, at the Society of Nuclear Medicine &amp; Molecular Imaging (SNMMI) annual meeting being held June 21st – 24th, 2025, in New Orleans, Louisiana. The data presented at SNMMI showed ATNM-400 has superior potency compared Xtandi&#xAE;&nbsp;(enzalutamide) and is highly efficacious in Xtandi&#xAE;&nbsp;resistant prostate models. Xtandi is an androgen receptor inhibitor (ARPI) therapy developed and marketed by Astellas and Pfizer that is approved for three stages of prostate cancer and generated sales of $5.9 billion in 2024. Actinium also presented additional new data showing ATNM-400 is more efficacious than PSMA-617 labeled with both Lutetium-177 (Lu-177) and Ac-225 and that ATNM-400 also overcomes resistance to Pluvicto&#xAE;&nbsp;(Lu-177-PSMA-617). Pluvicto&#xAE;&nbsp;is developed and marketed by Novartis and generated sales of $1.4 billion in 2024. ATNM-400 represents a transformational therapeutic candidate being developed to overcome limitations of current prostate cancer therapies such as Xtandi&#xAE;&nbsp;and Pluvicto&#xAE;&nbsp;and improve outcomes over what is currently achievable.

Actinium Pharma Reports New Preclinical Data From Non-PSMA Targeting Radiotherapy Prostate Cancer Candidate ATNM-400, At SNMMI Annual Meeting

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Initial clinical data expected in the second half of 2025 from this first-of-its-kind trial to administer a targeted radiotherapy conditioning agent with a commercial CAR-T therapy
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Iomab-ACT supported by results of NIH funded trial with MSK showing effective lymphodepletion of targeted immune cells resulting in negligible rates of CAR-T toxicities ICANS and CRS and CAR T-cell persistence with a novel CD19 CAR-T therapy
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Iomab-ACT has the potential to increase the addressable market for CAR-T therapies, which generated $4 billion in sales in 2024, by enabling improved access and better patient outcomes compared to current chemotherapy conditioning agents
NEW YORK, May 6, 2025 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE:<a class="ticker" href="https://www.benzinga.com/stock/ATNM#NYSE">ATNM</a>) (Actinium or the Company), a pioneer in the development of targeted radiotherapies, today announced that the first patient was enrolled on the trial studying Iomab-ACT targeted conditioning with a commercial CAR-T therapy at the University of Texas Southwestern Medical Center (UTSW) (<a href="https://c212.net/c/link/?t=0&amp;l=en&amp;o=4420488-1&amp;h=3859462182&amp;u=https%3A%2F%2Fclinicaltrials.gov%2Fstudy%2FNCT06768905%3Fintr%3DIomab-ACT%26rank%3D1&amp;a=NCT06768905">NCT06768905</a>). Initial clinical data from this trial is expected in the second half of 2025. Actinium is developing Iomab-ACT as a targeted radiotherapy conditioning agent intended to replace non-targeted chemotherapeutic conditioning agents such as Fludarabine and Cyclophosphamide (Flu/Cy) to address serious CAR-T related toxicities including immune effector cell-associated neurotoxicity (ICANS) and cytokine release syndrome (CRS), to potentially improve patient access and outcomes. Currently, there are seven CAR-T therapies approved for certain leukemias and lymphomas and multiple myeloma, that over 150,000 patients are diagnosed with annually. &nbsp;In 2024, the seven approved CAR-T therapies generated over $4 billion in sales and CAR-T therapies are forecasted to reach $12 billion in annual sales in 2030.

Actinium Announces Enrollment Of First Patient In The Iomab-ACT Commercial CAR-T Trial At The University Of Texas Southwestern Medical Center; Initial Clinical Data Expected In The Second Half Of 2025

-&nbsp; Results highlight ATNM-400's potential as a transformative therapeutic option for prostate cancer patients with unmet clinical needs as expression of the target receptor for ATNM-400 persists following Pluvicto therapy and ATNM-400 demonstrates sustained tumor control after Pluvicto stops working
-&nbsp; ATNM-400 showed greater tumor growth inhibition compared to Pluvicto in prostate cancer models with 99.8% tumor growth inhibition achieved with a single 40 µCi/kg dose of ATNM-400 demonstrating the potential to be offered as an alternative option
-&nbsp; ATNM-400 was well tolerated with no apparent toxicities at two different dose levels, with efficient clearance from essential organs
NEW YORK, April 28, 2025 /PRNewswire/ -- Actinium Pharmaceuticals, Inc.&nbsp;(NYSE:<a class="ticker" href="https://www.benzinga.com/stock/ATNM#NYSE">ATNM</a>) (Actinium or the Company), a pioneer in the development of targeted radiotherapies, today announced preclinical results with ATNM-400 in prostate cancer models presented at the American Association for Cancer Research (AACR) Annual Meeting. ATNM-400 is a novel, non-PSMA targeting, first in class targeted radiotherapy utilizing the Actinium-225 (Ac-225) radioisotope that Actinium is evaluating in prostate cancer models prior to and following treatment with Pluvicto. Pluvicto (Lu-177-PSMA-617) is a prostate-specific membrane antigen (PSMA) directed radiotherapy radiolabeled with the beta-particle emitter, Lutetitium-177 (Lu-177) is approved for patients with metastatic castration-resistant prostate cancer. Pluvicto is marketed and sold by Novartis and generated sales of $1.39 billion in 2024.

Actinium Pharmaceuticals To Present Business Update At Trump Mar-A-Lago Club Today; Revitalized Clinical Programs Focused On 3 Separate Market Opportunities In Myeloid Malignancies, Solid Tumors And Cell & Gene Therapy Conditioning With Clinical Data Expected In 2025

Actinium Pharmaceuticals, Inc.&nbsp;(NYSE:<a class="ticker" href="https://www.benzinga.com/stock/ATNM#NYSE">ATNM</a>) (Actinium or the Company), a pioneer in the development of targeted radiotherapies,&nbsp;today announced it has entered into an agreement for the supply of Actinium-225 (Ac-225) with Eckert &amp; Ziegler. Under this agreement, Actinium Pharmaceuticals will have access to Eckert &amp; Ziegler's high-quality Actinium-225 to further develop its lead product Actimab-A as well as additional early and late-stage development candidates for both U.S. and international clinical trials.
&nbsp;
Targeted radiotherapies using Ac-225 have shown great promise in the treatment of cancer. The radioisotope releases powerful alpha particles with high energy and low penetration depth, enabling precise targeting of tumor cells, including hard-to-reach micrometastases, while minimizing effects on surrounding healthy tissue. Actimab-A is an Ac-225 based radiotherapy agent, directed against CD33, a receptor overexpressed in patients with acute myeloid leukemia (AML) and other myeloid indications.
