Linda J. Van Eldik, Ph.D., director of the University of Kentucky Sanders-Brown Center on Aging, is part of a $1.5 million grant to help further research into a possible treatment for Alzheimer's disease. A four-year grant from the National Institute on Aging of the National Institutes of Health to Northwestern University includes a $611,676 subaward to UK. Van Eldik, the Dr. E. Vernon Smith and Eloise C. Smith Alzheimer's Research Endowed Chair, serves as principal investigator on UK's award.

This is a multi-principal investigator award, representing the continuation of a long-standing collaboration between myself and Dr. D. Martin Watterson at Northwestern, which has brought this promising small molecule drug candidate from concept to human trials."

The funding will help move work forward on a brain-penetrant, small molecule drug candidate developed by Van Eldik and her colleagues called MW189. In 2020, Van Eldik reported the first human clinical study of MW189 that suppresses disease-induced inflammation and injury of the brain.

"This compound is currently in a phase 2a clinical trial as an intravenous formulation in patients with intracerebral hemorrhage," said Van Eldik. "However, our long-term goal is to develop this drug as an oral formulation for patients with Alzheimer's disease or other related dementias. To do this, we must fill remaining gaps necessary to bring MW189 to a future clinical study in Alzheimer's patients."

Van Eldik lays out several steps to reaching that long-term goal. First, the team will need to produce a new batch of clinical drug substance and oral drug product manufactured in compliance with recent FDA guidance on drug quality for human clinical trials that may require daily oral administration for years. Second, researchers will need to perform extended toxicology studies in two animal species to provide refined dosing parameters for long-term administration in humans. The last step will be obtaining authorization for an investigational new drug application for future clinical trials in early Alzheimer's disease and related dementias.

"At the end of this project, we will be positioned to immediately proceed to a phase 2a clinical study of Alzheimer's disease patients. This drug has the potential to be a first-in-class disease-modifying therapy for Alzheimer's disease and related dementias," said Van Eldik. "In addition, because the drug acts on a mechanism that drives disease progression or susceptibility in multiple central nervous system disorders with dysregulated inflammation, this work could have scientific impact in a number of different brain disorders."
