INmune Bio Inc. Announces Novel MRI Biomarker Data Demonstrating Improvement in Gray Matter in Patients with Alzheimer’s Disease

Analysis of MRI scans in participants from an open label Phase 1b study demonstrates that CDM®, a novel gray matter biomarker, is improved following three months of treatment with XPro1595TM

Boca Raton, Florida, July 11, 2023 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease, reveals new findings from data to be presented at the annual Alzheimer’s Association International Conference (AAIC) in Amsterdam, Netherlands. AAIC is the largest medical meeting focused on Alzheimer’s Disease (AD).

“One of the difficulties in developing drugs for AD is the inability to quantify the disease and measure changes at the tissue or microstructure level. The current approaches to measure brain changes utilize imaging techniques that measure the whole brain,” said RJ Tesi, M.D., INmune Bio’s Chief Executive Officer. “To observe whole brain changes in AD often takes a year or longer.  Because whole brain changes are a sum of microstructural changes, we can more quickly assess the potential of a therapy through microstructural measurements such as Cortical Disarray Measurement (CDM®).”

Emerging imaging techniques that assess microstructural changes are rapidly advancing.  INmune Bio is a pioneer in the use of novel microstructural neuroimaging biomarkers to measure pharmacodynamic activity of treatment with XProTM in patients with AD. INmune previously reported that treatment using XProTM improved microstructural changes in the white matter tracts that are most affected in AD patients in participants from our Phase 1b trial. This new analysis reports similar findings in the gray matter of these same participants. The results demonstrate a dose dependent enhancement in gray matter measures throughout the brain in AD patients treated with XProTM. The changes in microstructural cortical gray matter structure were measured using Cortical Disarray Measurement and one metric in particular demonstrated significance PerpPD+.  CDM® is a novel gray matter measure that is more effective than standard whole brain volumetric changes in predicting cognitive decline.   Notably, the greatest improvement was observed in the gray matter of brain regions where Alzheimer’s disease originates.

To better understand the utility of PerpPD+ in patients with AD treated with XPro™, associations with other AD biomarkers were assessed.  Baseline levels of PerpPD+ were highly correlated with baseline levels of cerebral spinal fluid biomarkers of AD pathology (amyloid and tau), inflammation (YKL-40, GFAP and sTREM2), and cognitive status (MMSE scores).  “These data provide additional evidence that XProTM may be having a specific impact on the brain regions most impacted by AD at the microstructural level within three months of starting treatment,” said CJ Barnum Ph.D., VP of CNS Drug Development at INmune Bio. “These findings serve as indicators of early target engagement for XProTM in AD and add further support for use of noninvasive diffusion MRI in AD trials. This new biomarker tool, when added to our existing suite of biomarkers, should improve the speed, and decrease the risk of CNS drug development.”

INmune Bio Presentations Discussed at AAIC 2023

  • Cortical microstructural MRI for detection of early target engagement in AD drug trials: Post-hoc analysis of exploratory outcomes from a phase 1b safety study for XPro1595TM in AD
  • Clinical and biomarker correlates of region-specific diffusion MRI metrics in a short-term, Phase1b clinical trial for XPro1595TM in Alzheimer’s disease

About Cortical Disarray Measurement (CDM®)

PerpPD+ is a novel measure of cortical diffusivity and key metric included in the Cortical Disarray Measurement (CDM®) technology developed by Oxford Brain Diagnostics, Ltd, Oxford (UK). Cortical Disarray Measurement (CDM®) software has been granted Breakthrough Device designation by the FDA and is currently in use to assess changes in GM microstructure as a secondary outcome in our ongoing Phase 2 trial for XPro1595TM in AD. The PerpPD+ metric represents the diffusion components perpendicular to cortical GM minicolumns, is an indicator of microscopic disruption in cortical GM when increased in AD and has been shown to be more sensitive than standard volumetrics to changes in other indicators of synaptic structure, neuroinflammation and neurodegeneration across the AD continuum.

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 DN-TNF product platform utilizes dominant-negative technology to selectively neutralize soluble TNF, a key driver of innate immune dysfunction and mechanistic target of many diseases. DN-TNF is in clinical trials to determine if it can treat cancer (INB03™), Early Alzheimer’s disease, and treatment resistant depression (XPro™). The Natural Killer Cell Priming Platform includes INKmune™ aimed at priming the 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 malignancies, solid tumors and chronic inflammation.
