INmune Bio Announces Submission of Phase 2 MINDFuL Trial Results in Alzheimer’s Disease to npj Dementia, a Nature Portfolio Journal

Boca Raton, FL, Sept. 29, 2025 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB), a clinical-stage inflammation and immunology company, today announces the submission of a manuscript detailing the results of its Phase 2 MINDFuL trial. The manuscript, titled, “XPro1595, a Selective Soluble TNF Neutralizer, in Early Alzheimer’s Disease with Inflammation (ADi): Results from the Phase 2 MINDFuL Trial,” has been submitted for peer review to npj Dementia, a Nature Portfolio journal.

The detailed manuscript provides a comprehensive analysis of the trial, which evaluated the safety and efficacy of XPro™ in patients with early Alzheimer's disease and biological signs of inflammation. While the study did not meet its primary endpoint in the overall population, the findings reveal a promising signal in a prespecified subgroup of patients with both amyloid pathology and a high inflammatory burden, defined by two or more biomarkers of inflammation, referred to as the ADi population.

"The publication of the MINDFuL trial results with the scientific community highlight the potential therapeutic value of our XPro platform. We are encouraged by the trial results of the subgroup analysis, in addition to the demonstrated strong safety profile, which we believe favorably positions XPro™ for clinical trial advancement,” said CJ Barnum, VP of Neuroscience at INmune Bio.

Key findings within the biomarker-enriched ADi population include:

• XPro™ demonstrated consistent positive trends across cognitive, neuropsychiatric, and biological endpoints, which suggests that targeting neuroinflammation by selectively neutralizing soluble TNF may offer benefits for a specific subset of individuals living with Alzheimer's disease, supporting continued development of XPro™ as a precision medicine approach for this patient group
• Complete absence of amyloid-related imaging abnormalities (ARIA), a serious side effect commonly associated with amyloid-targeting therapies. This favorable safety profile was observed in a high-risk patient population, including significant numbers of APOE4 carriers, patients receiving anticoagulant medications, and individuals with multiple cerebral microbleeds. This distinguishes XPro™ from other treatments and suggests its potential for broader use, including in combination therapies

“Data in the subgroup analysis strongly suggests XPro™ will benefit the trial’s target patient population while also providing a strong rationale for our upcoming end-of-Phase 2 discussions with regulatory authorities, including the FDA, EMA, and MHRA,” stated David Moss, CEO of INmune Bio. “We anticipate receiving regulatory feedback from the FDA in the first quarter of 2026."

About XPro™

XPro™ (also referred to as “XPro1595”) is a next-generation inhibitor of tumor necrosis factor (TNF) that is currently in clinical trial and acts differently than currently available TNF inhibitors in that it neutralizes soluble TNF (sTNF), without affecting trans-membrane TNF (tmTNF) or TNF receptors. XPro™ could have potential substantial beneficial effects in patients with neurologic disease by decreasing neuroinflammation.

About INmune Bio Inc.

INmune Bio Inc. is a publicly traded (NASDAQ: INMB), clinical-stage biotechnology company focused on developing treatments that target the innate immune system to fight disease. INmune Bio has three product platforms: the Dominant-Negative Tumor Necrosis Factor (DN-TNF) product platform utilizes dominant-negative technology to selectively neutralize soluble TNF, a key driver of innate immune dysfunction and a mechanistic driver of many diseases. The second program, CORDStrom™, is a proprietary pooled, allogeneic, human umbilical cord-derived mesenchymal Stromal/Stem cell (hucMSCs) platform that recently completed a blinded randomized trial in recessive dystrophic epidermolysis bullosa. The third program, INKmune®, is designed to prime a patient’s natural killer cells to eliminate minimal residual disease in patients with cancer and is currently in a trial in metastatic castration-resistance prostate cancer.
