INmune Bio Reports New Phase 2 Grey Matter Imaging Data at CTAD Conference Reinforcing XPro1595’s Evidence Base in High-Inflammation Alzheimer’s Patients

Boca Raton, FL, Dec. 01, 2025 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB), a clinical-stage biotechnology company developing inflammation and immunology therapies targeting innate immune dysfunction, announces new neuroimaging data from its Phase 2 MINDFuL trial of XPro1595 in patients with early Alzheimer’s disease (AD) and elevated neuroinflammation. The results will be presented at the 18th Clinical Trials on Alzheimer’s Disease conference (CTAD), being held on December 1-4, 2025 in San Diego, CA.

The new analyses add to the growing body of clinical, biomarker, and imaging evidence supporting XPro1595’s mechanism of selectively neutralizing soluble TNF (sTNF). The data further validate the Company’s strategy of targeting inflammation-driven AD, a large, underserved subset representing a significant unmet need and potential commercial opportunity.

New Grey Matter Signals Strengthen Biological Rationale for XPro1595

Using PerpPD+, a next-generation MRI imaging analysis that quantifies the diffusion components of water molecules that are perpendicular to the cortical gray matter’s minicolumns in the brain (PerpDP+, from Oxford Brain Diagnostics), investigators observed a trend towards slowed neurodegeneration progression in patients receiving XPro1595. These analyses focused on participants with early AD and high inflammatory burden (ADi), including the dose-compliant subgroup.

The PerpPD+ findings suggest attenuated increases in cortical disarray, an imaging hallmark associated with neurodegeneration. These results reinforce previously reported directional improvements across biological, cognitive, and neuropsychiatric endpoints and align with XPro1595’s mechanism of reducing innate immune dysfunction.

“These PerpDP+ data represent one of the clearest signals yet that selectively neutralizing soluble TNF can interrupt the neurodegenerative cascade at its microstructural root in AD driven by inflammation,” said Dr. CJ Barnum, Head of Neuroscience at INmune Bio. “We are excited to analyze the remaining imaging data and to report on this at subsequent meetings and in publications.”

Dr. Steven Chance, CEO of Oxford Brain Diagnostics added:

“XPro1595 is one of the pioneering interventions to examine the powerful role the innate immune system plays in Alzheimer’s disease pathology. Quantitative and precise biomarkers like cortical disarray measurement (CDM) was one of the secondary outcome measures in INmune Bio’s Phase 2 Alzheimer’s study. In the dose compliant participants, CDM showed a trend for reduced cortical disarray, indicating lower neurodegeneration.”

Key Highlights

Additional Imaging Analyses Expected in 2026

INmune Bio confirmed that additional MRI analyses from the MINDFuL trial are ongoing and will be presented when available. These forthcoming data are expected to provide a broader picture of XPro1595’s tissue-level impact on both gray- and white-matter integrity in ADi.

The Company believes totality of data generated to date, including the neuroimaging findings, position XPro1595 as a promising first-in-class disease-modifying therapy for the large subset of Alzheimer’s patients with elevated neuroinflammation. This population has limited treatment options, and no currently approved therapy is designed to target innate immune dysfunction.

About XPro™

XPro™ (Xpro1595, pegipanermin) is a next-generation inhibitor of soluble tumor necrosis factor (sTNF) that preserves trans-membrane TNF (tmTNF) and TNF-receptor signaling. By selective neutralizing sTNF, XPro™ aims to restore healthy innate immune function without the immunosuppressive liabilities associated with traditional TNF inhibitors. XPro™ is currently in clinical development for neurological diseases driven by chronic inflammation.

Peer Reviewed Study Highlights Therapeutic Potential Around Application of Stromal Cell Therapies Such as INmune Bio’s CORDStrom™ Platform

Boca Raton, FL, Dec. 04, 2025 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB) (“INmune” or the “Company”), a clinical-stage inflammation and immunology company, announces a recently published overview of future applications and research areas for mesenchymal stromal cell (MSC) therapies, such as INmune’s CORDStrom™ platform. The article, titled, “Fate and Function of Exogenously Administered MSCs: Current Insights and Future Directions,” was published in the peer-reviewed journal Cytotherapy. One of the lead authors of the paper was INmune Bio’s lead scientist for CORDStrom™ R&D, Dr Nikita M. Patel, M.Sci.,Ph.D.

The article, was the result of an invitation-only working party of basic, clinical and translational scientists working on MSCs and available on Cytotherapy’s website, reviews the current knowledge-base and critical gaps in order to formulate experimental questions designed to enhance development of MSC therapies such as the CORDStrom™ platform. These topics included systemic delivery of MSCs, local and/or depot-delivery (which is the method for the Company’s CORDStrom™ platform), and in vivo persistence.

“While CORDStrom™ is initially being developed for use in RDEB, in which we expect to file a BLA and MAA in 2026, publications such as this one provide important scientific background for future development of the CORDStrom™ platform. Stromal cell therapies are an important clinical advancement that may have significant impact in multiple indications including inflammation, immunomodulation, and wound healing,” said Dr. Mark Lowdell, INmune Bio CSO. “Nikita’s role within INmuneBio supports continued advancement in the knowledge base on MSCs. We believe her contributions as one of the senior authors to this article, and the insightful questions asked by the panel, will have an important impact on the development of the use of MSCs in general in addition to the ongoing development of our CORDStrom™ platform.”
