Boca Raton, Florida, May 10, 2022 (GLOBE NEWSWIRE) — Inmune Bio, Inc. (NASDAQ: INMB) (“INMB” or “the Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease is pleased to announce that Professor Lesley Probert Ph.D., head of the department of Immunology at the Hellenic Pasteur Institute in Athens, Greece will be presenting data on the effects of tumor necrosis factor (TNF) in MS at the 3rd European Conference on Neuroinflammation concluding in London today.
Professor Probert has been researching the role of TNF in promoting demyelination (destruction of myelin) for more than a decade.
Myelin is a critical component to normal central nervous system function. The myelin sheath, produced by oligodendrocytes, is critical for normal nerve function. When the myelin sheath is damaged, nerve cells cannot transmit signals efficiently and, if the damage persists, the cells undergo neurodegeneration and die. Demyelination is a common feature across many neurodegenerative diseases. A decade ago, Professor Probert’s laboratory showed that in rodent models of MS, XProTM promoted remyelination (the repair of myelin) in white matter whereas currently approved non-selective TNF inhibitors promote demyelination. Her laboratory works to understand why soluble TNF causes demyelination and identifies therapies that promote remyelination.
In the presence of neuroinflammation, dysfunctional microglial cells promote nerve cell death, synaptic impairment, and demyelination. The data presented today show that XProTM also promotes remyelination within the gray matter of the brain by inducing the brains natural repair mechanisms. Neutralization of soluble TNF with XProTM activates pro-microglial and pro-astroglial responses to clear (phagocytize) degenerated myelin and promote remyelination in cortical areas. These data are presented in detail here.
“This works confirms the importance of normal microglial function in promoting remyelination.”, said Prof Probert of the Hellenic Pasteur Institute, “Soluble TNF paralyzes the ability of microglial cells to remove myelin debris. By eliminating soluble TNF, glial phagocytosis returns, myelin debris is cleared, and oligodendrocytes can remyelinate damaged axons.”
The ability of XProTM to promote remyelination has been demonstrated in the patients who received 12 months of XProTM for treatment of Alizheimer’s Disease in the recently concluded successful Phase I trial. Remyelination is measured using radial density tensor imaging (RDt), one of the novel white matter MRI analytic measured in the patients by INmune Bio’s imaging partner, IMEKA. In patients on the 1mg/kg/week dose, remyelination is detected at 3 months and continued for at least 12 months.
“One reason few understand that demyelination is part of degenerative diseases such as AD is because it has been difficult to measure in patients.”, said CJ Barnum PhD, VP of CNS Development for INmune Bio, “Using non-invasive MRI imaging metrics, we can see and quantify the amount of demyelination and remyelination in patients with neurodegenerative disease. Time and experience of more patients treated will tell if XPro’s ability to promote remyelination in diseases such as ADi and MS translates into measurable clinical benefits’”
XPro1595™ (XPro™) is a next-generation inhibitor of tumor necrosis factor (TNF) that 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 Alzheimer’s 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 two product platforms that are both in clinical trials: 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. DN-TNF product candidates are in clinical trials to determine if they can treat cancer (INB03™), Mild Alzheimer’s disease, Mild Cognitive Impairment and treatment-resistant depression (XPro™). The Natural Killer Cell Priming Platform includes INKmune™ developed to prime a patient’s NK cells to eliminate minimal residual disease in patients with cancer. INmune Bio’s product platforms utilize a precision medicine approach for the treatment of a wide variety of hematologic and solid tumor malignancies, and chronic inflammation.
