Actinium Pharmaceuticals (NYSE: ATNM) announced that first-ever preclinical data for ATNM-400, a first-in-class Actinium-225 antibody radioconjugate, will be presented at the AACR-NCI-EORTC conference Oct 22–26, 2025.
Preclinical findings reportedly show potent anti-tumor activity in EGFR-mutant NSCLC models, overcoming resistance to osimertinib and showing synergy with osimertinib and with enzalutamide in prostate models; animal data included 40% complete tumor regressions in a prostate setting. The poster is scheduled for Oct 25, 2025, and the abstract will be available online Oct 22, 2025 at 12:00 PM ET.
Actinium (NYSE: ATNM) announced that preclinical data for ATNM-400, a first-in-class Ac-225 antibody radioconjugate, will be presented at the 32nd Annual Prostate Cancer Foundation Scientific Retreat on October 23, 2025. The poster highlights durable anti-tumor activity in metastatic castration-resistant prostate cancer models, including activity in tumors resistant to enzalutamide and 177Lu-PSMA-617, and reports superior efficacy versus 225Ac-PSMA-617.
The release states ATNM-400 targets a distinct, non-PSMA antigen that is overexpressed after ARPI therapy, showed synergy with enzalutamide, and improved overall survival in preclinical models. The poster will be viewable online via the company investor relations page after the retreat.

Actinium Pharmaceuticals (NYSE: ATNM) has presented promising preclinical results for ATNM-400, a novel targeted radiotherapy for prostate cancer, at the AACR Annual Meeting. The data shows ATNM-400 outperforms Pluvicto, achieving 99.8% tumor growth inhibition with a single 40 µCi/kg dose.
Unlike Pluvicto and most prostate cancer radiotherapies that target PSMA, ATNM-400 is a first-in-class treatment targeting a distinct non-PSMA receptor that remains highly expressed even after Pluvicto treatment. The therapy utilizes Actinium-225, a more potent alpha-particle emitter than Lutetitium-177, causing irreversible DNA breaks with potentially fewer off-target effects.
Key findings demonstrate ATNM-400's efficacy in Pluvicto-resistant tumors, rapid internalization, sustained tumor uptake, and efficient clearance from essential organs. The treatment was well-tolerated with no apparent toxicities at both tested dose levels.
