INmune Bio, Inc. Announces Interim Phase Ib Data Demonstrating That XPro1595 Decreases Neuroinflammation in Patients with Alzheimer’s Disease

Excerpt from the Press Release:

“LA JOLLA, Calif., July 13, 2020 (GLOBE NEWSWIRE) — INmune Bio, Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness a patient’s innate immune system to fight disease, today reported clinical data demonstrating that its lead drug candidate, XPro1595, decreases neuroinflammation in patients with Alzheimer’s disease. Interim results from a Phase Ib clinical trial show that treatment with XPro1595 decreases white matter free water, a biomarker of neuroinflammation measured by MRI. XPro1595 is a next-generation inhibitor of tumor necrosis factor (TNF) that selectively neutralizes soluble TNF, an inflammatory cytokine implicated in Alzheimer’s pathology, without affecting transmembrane TNF or the TNF receptors.

Specifically, INmune compared biomarker data obtained from six patients treated with XPro1595 for 12 weeks with data from 25 Alzheimer’s patients from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) that are part of a natural history database in patients with Alzheimer’s. Over a 12-week period, whole brain inflammation increased by 5.1% in the ADNI patients compared to an increase of 1.7% and a decrease of 2.3% in patients treated weekly with 0.3mg/kg or 1.0mg/kg of XPro1595, respectively. A more detailed analysis revealed a 40.6% reduction in neuroinflammation in the Arcuate Fasciculus in patients treated with XPro1595. The Arcuate Fasciculus is a major white matter anterior/posterior tract (white matter bundle) containing long and short fibers that connects the frontal, parietal and temporal lobes and is important for language and short-term memory. By contrast, the ADNI cohort had a 4.6% increase in Arcuate Fasciculus neuroinflammation.”
