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

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.

“We are extremely encouraged by these findings at such an early stage in our clinical trial,” said CJ Barnum, Ph.D., Director of Neuroscience at INmune. “Not only do we see a clear reduction in neuroinflammation, but we also know where in the brain this is occurring, which may inform us on the domains of cognition that might be affected.”

According to Sharon Cohen, M.D., FRCPC, a neurologist and Medical Director of Toronto Memory Program who is not involved with the clinical trial: “The preliminary results from INmune Bio’s Phase Ib study add to the growing enthusiasm for tackling neuroinflammation in the treatment of Alzheimer’s disease. Furthermore, MRI assessment of free water content in the brain holds promise as an exciting surrogate marker for tracking the impact of such treatment.” 

INmune will host a key opinion leader (KOL) event at 8 a.m. EDT tomorrow. A brief presentation of the data by the company will be followed by a panel discussion and Q&A with:

• Dr. Rosalyn Lai, a psychiatrist and Principal Investigator at KaRa MINDS in Sydney, Australia, that is enrolling patients in the Phase Ib Alzheimer’s study.
• Max Descoteaux, Ph.D., Professor, Computer Science Department, Sherbrooke University, CSO of Imeka and an expert in imaging brain connectivity, from state-of-the-art diffusion MRI acquisition, reconstruction, tractography, processing and visualization.
• Judith Jaeger Ph.D., President and Principal Scientist of CognitionMetrics, LLC, an internationally recognized cognitive neuropsychologist. 
• Malu Tansey, Ph.D., a professor of Neuroscience and Neurology at the Medical College of the University of Florida, and an internationally recognized expert in neuroinflammation and Alzheimer’s disease.

About XPro1595

XPro1595 is a next-generation inhibitor of tumor necrosis factor (TNF) that acts differently than currently existing TNF inhibitors in that it neutralizes soluble TNF (sTNF) without affecting trans-membrane TNF (tmTNF) or TNF receptors. XPro1595 could have beneficial effects in patients with Alzheimer’s disease by decreasing neuroinflammation. For more information about the importance of targeting neuroinflammation in the brain to improve cognitive function and restore neuronal communication visit this section of the INmune Bio’s website.  

About XPro1595 Clinical Trial

XPro1595 is currently being evaluated in Phase Ib clinical trial in Alzheimer’s disease patients who have biomarkers of inflammation to determine if neutralizing soluble TNF can decrease those biomarkers of neuroinflammation. There cannot be any assurance about the results of this trial.

Adults (>18 years old) diagnosed with probable Alzheimer’s disease defined by the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria, confirmed with inflammatory biomarkers, are being enrolled in this multicenter, Phase Ib open-label study. The study will follow patients during a 12-week period to determine the safety and the ability of XPro1595 to reduce neuroinflammation using a combination of biomarkers of inflammation. The study will examine inflammatory and disease-related biomarkers before treatment, at the halfway point, and at the end. Cognitive and neuropsychiatric symptoms will be also be measured during the trial. The study will identify the dose of XPro1595 to be used in a larger Phase II disease modification study.

Clinical sites are located in Australia and include KaRa MINDS in New South Wales, Central Adelaide Local Health Network in South Australia, Austin Health and Alfred Health in Victoria, and The Australian Alzheimer's Research Foundation in Western Australia.
