EIP Pharma Announces Presentation of Neuroimaging Data Exhibiting Potential Effects of Neflamapimod on Cholinergic Structure and Function at AD/PD™ 2023

Structural and functional brain MRI of patients before and after neflamapimod treatment shows increased NbM volume and increased functional dynamic connectivity between NbM and deep grey matter

BOSTON, April 3, 2023 /PRNewswire/ -- EIP Pharma Inc., a clinical stage company focused on developing treatments for neurodegenerative diseases, today announced the oral presentation by academic investigators from the Amsterdam University Medical Center of neuroimaging results from a phase 2a clinical study in patients with early Alzheimer's disease (AD) at the International Conference on Alzheimer's and Parkinson's Diseases (AD/PD™) 2023, which took place virtually and in person March 28 – April 1, 2023, in Gothenburg, Sweden.

The goal of this exploratory analysis was to assess the treatment effects of neflamapimod on the Nucleus basalis of Meynert (NbM), the largest cluster of cholinergic neurons in the basal forebrain, assessed by MRI (magnetic resonance imaging), in a previously completed phase 2a study in patients with early AD (n=15). Structural and MRI assessments had been conducted at baseline and following 12 weeks of treatment with neflamapimod. The analysis demonstrated that the NbM volume was statistically significantly higher at the end of treatment (EOT, mean 3.1% higher vs. baseline, p=0.03); with 8 of 15 patients having greater than 3% higher NbM volume at EOT, compared to baseline. Treatment with neflamapimod was also associated with a statistically significantly higher functional dynamic connectivity between the NbM and deep grey matter (DGM) at EOT (mean 11% higher vs. baseline, p=0.04); with 6 of 13 showing a greater than 10% higher dynamic NbM-DGM connectivity at EOT, compared to baseline. The potential regression of atrophy and recovery of function in neflamapimod-treated patients in this study suggests a restoration of cholinergic neurons in the NbM and are supportive of data generated in previous preclinical studies that demonstrated neflamapimod reversed the neurodegenerative process in the basal forebrain cholinergic system.

"The data presented this weekend at AD/PD 2023 continue to support the thesis that inhibiting p38 MAP kinase alpha (p38α) activity has a positive impact on the cholinergic degenerative process and that functional and structural MRI assessments of the NbM may have utility as biomarkers for therapeutic effects when patients are treated with neflamapimod," said John Alam, MD, Chief Executive Officer of EIP Pharma. "We are encouraged by these findings and are pleased to share these important results with the medical and scientific community."

About Neflamapimod

Neflamapimod is an investigational drug that is an orally administered small molecule brain penetrant that inhibits p38MAP kinase alpha (p38a). P38a, which is expressed in neurons under conditions of stress and disease, plays a major role in inflammation-induced synaptic toxicity, leading to synaptic dysfunction. Neflamapimod is currently being developed for the treatment of dementia with Lewy bodies (DLB) and is the first treatment with the potential to have a positive impact on cognition, function and motor function.

In preclinical studies, neflamapimod reversed synaptic dysfunction, including and particularly within the part of the brain most impacted in DLB – the basal forebrain cholinergic system. In Phase 1 and Phase 2 clinical studies involving more than 300 participants, neflamapimod has been shown to be generally well tolerated. Results from the AscenD-LB Phase 2a clinical study demonstrated that neflamapimod significantly improved dementia severity compared to placebo and also showed significant improvement on motor function compared to placebo. At the highest dose evaluated, neflamapimod improved cognition. The combined preclinical and clinical data are consistent with neflamapimod treating the underlying DLB disease process and suggest it has the potential to be the first disease-modifying treatment for DLB. Neflamapimod was granted Fast Track status by the U.S. Food and Drug Administration for the treatment of DLB, and EIP Pharma was recently awarded a $21 million grant from the National Institutes of Health's National Institute on Aging (NIA) to evaluate neflamapimod in a Phase 2b clinical study in DLB. The NIA grant funds will be disbursed over the course of study as the costs are incurred.

About EIP Pharma

EIP Pharma, Inc. is a privately held clinical-stage biotechnology company advancing CNS-focused therapeutics to benefit patients with a range of debilitating neurodegenerative diseases. EIP Pharma is currently developing neflamapimod, an investigational orally administered small molecule brain penetrant that inhibits p38MAP kinase alpha (p38a). Neflamapimod has the potential to treat synaptic dysfunction, the reversible aspect of the underlying neurodegenerative processes that cause disease in dementia with Lewy bodies (DLB) and certain other major neurological disorders.
