AIM ImmunoTech Announces Publication of Journal Article On the Positive Effect of Ampligen and Interferon-Alpha on Tumor Growth

New peer-reviewed article appears in the Journal for ImmunoTherapy of Cancer

OCALA, Fla., Sept. 22, 2025 (GLOBE NEWSWIRE) -- AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”) today announced that the Journal for ImmunoTherapy of Cancer (JITC) has published a new peer-reviewed article providing evidence of a positive combination effect of AIM’s drug Ampligen and interferon-alpha on tumor growth and subsequent subject survival.

The paper concluded that the ability of systemic chemokine modulation to eliminate the PD-1-resistance of cold tumors indicates that intratumoral cytotoxic t-lymphocyte accumulation, rather than tumor immunogenicity, is the key factor limiting the therapeutic effectiveness of immune checkpoint inhibitors. These data suggest a broad therapeutic potential of tumor microenvironment reprogramming strategies.

The article, titled "Synergy between TLR3-ligand and IFN-α in the transient sensitization of ‘Cold’ tumors to PD-1 blockade and the induction of systemic immunity," was published in JITC on September 18.
