White matter myelin integrity demonstrated a statistically significant treatment difference at Week 24 in the modified intent-to-treat population (p &lt; 0.01), with larger effects observed in patients selected using the company’s biomarker enrichment strategy. BOCA RATON, Fla., July 09, 2026 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ: INMB), a late-stage biotechnology company focused on inflammation and immunology, today announced new imaging data from its Phase 2 study of XPro in patients with early Alzheimer’s disease (AD). The data, to be presented at the Alzheimer’s Association International Conference (AAIC), support early, concordant treatment-related effects across independent white matter and gray matter imaging endpoints. The presentation, titled “Concordant White Matter and Cortical Treatment Effects in a Phase 2 Study of XPro1595 in Early Alzheimer’s disease,” highlights the full chi-separation analysis of white matter myelin, together with cortical disarray measurement (CDM), an advanced diffusion-MRI measure of gray matter microstructure. The two techniques rely on different MRI contrast mechanisms: chi-separation uses magnetic susceptibility, while CDM uses water diffusion. They also use separate acquisition sequences and processing pipelines and, in this study, were applied to different tissue compartments. Because these methodologically independent measures changed in the same direction, their concordance supports the interpretation that the observed changes are treatment-related and reflect effects on brain microstructure. “Microstructural integrity in gray and white matter represents an important set of biomarkers in Alzheimer’s disease because these changes reflect early pathological processes that contribute to cognitive decline,” stated Dr. CJ Barnum, Vice President of Neuroscience at INmune Bio. "Detecting a treatment effect on white matter myelin within just 24 weeks, corroborated by cortical gray matter changes measured using an independent imaging method, supports the conclusion that XPro™ is engaging relevant biology earlier than traditional volumetric approaches would be expected to reveal." The upcoming AAIC presentation builds directly on the positive topline imaging results reported by INmune Bio on June 2, 2026. The results showed a statistically significant treatment effect on a white matter myelin biomarker in the modified intent-to-treat population at Week 24 (p&lt;0.01), with larger effects observed in patients selected using the company’s biomarker enrichment strategy. "XPro’s effect on myelination remains one of the most robust and consistent findings across our preclinical and clinical work, giving us real confidence in the drug and in target engagement," said David Moss, Chief Executive Officer of INmune Bio. "Showing an early, treatment-related effect on myelin, the tissue at the center of many neurologic diseases, using imaging sensitive enough to detect it speaks to the broader potential of selective soluble TNF inhibition, and reinforces our confidence in XPro’s potential." AAIC 2026 Poster Presentation INmune Bio will present expanded imaging analysis from the MINDFuL study at the Alzheimer's Association International Conference (AAIC) 2026, taking place July 12–15, 2026, in London, United Kingdom, and online. The poster, titled "Concordant White Matter and Cortical Treatment Effects in a Phase 2 Study of XPro1595 in Early Alzheimer's disease" (Abstract Control No. 13497), will be presented in the "Developing Topics: Biomarkers" in-person poster session on Sunday, July 12, 2026, from 7:30 a.m. to 4:15 p.m. local time in the Exhibit Hall. The poster will include longitudinal analyses, subgroup data, and mechanistic context for both the white matter myelin and complementary cortical microstructure imaging endpoints. About INmune Bio Inc. INmune Bio Inc. is a publicly traded (NASDAQ: INMB), late-stage biotechnology company focused on developing treatments that target the innate immune system to fight disease. Moving beyond early-stage exploration, the Company’s clinical-development strategy centers on advanced precision medicine, matching drug mechanisms directly to patient biology to optimize clinical outcomes. INmune Bio is actively advancing two late-stage product platforms toward registrational milestones: <ol type="1"><li style="margin-top:0in; margin-bottom:8pt;" value="1">CORDStrom™: A proprietary, pooled, allogeneic, human umbilical cord-derived mesenchymal stromal cell platform engineered to address the historical clinical challenges of donor variability and manufacturing inconsistency. Following successful clinical readouts in RDEB, the platform is transitioning to regulatory filing phases, with an MAA planned for the UK MHRA and EU EMA in 2026, alongside a planned U.S. Biologics License Application (BLA) submission.</li><li style="margin-top:0in; margin-bottom:8pt;">XPro1595™: A Dominant-Negative Tumor Necrosis Factor (DN-TNF) platform that selectively neutralizes soluble TNF (sTNF) to reduce pathological neuroinflammation without compromising protective immune function. Backed by recently granted FDA Fast Track designation and successful regulatory alignment from an End-of-Phase 2 meeting, XPro1595™ is positioned for an integrated Phase 2b/3 seamless adaptive registrational program in neuroinflammation-enriched early Alzheimer’s disease.</li></ol> To learn more about INmune Bio’s pipeline and its approach to harnessing the innate immune system, please visit <a href="https://www.globenewswire.com/Tracker?data=vwYfemoZkvzddxcURIDEaPnfZKwi2QAI1OBDwszTne3cyt6g6iXVqRN1Toj2_8cjTDBwoR7pxPVgWqDWJizIpbUlLUujJtIaDAzEdOJetIPhQ2TEovgP7p7rkDHnAK_gVApQY9JXFuFIJD_Q8ugPDDOZ9noIcc8ukNpw7mjPd305nmFy-kQDIw3D9MkvQ4j2eIse46AhZlx8FFBpkdsKdq-emXcsVToVfKz24KCBLqHOavzWeG1b1opDwGtTP-sTmSWKq5l-Ak48mlzIJSQN4A==" rel="nofollow" target="_blank" title="www.inmunebio.com">www.inmunebio.com</a>.
