Eisai and Boston University School of Medicine Announce Research Collaboration to Study the Effects of Alzheimer's Disease-Associated Genetic Variants on Brain

ANDOVER, Mass. and BOSTON, Jan. 30, 2018 /PRNewswire/ -- Eisai Inc. and Boston University School of Medicine have formed a research collaboration to study the effects of Alzheimer's disease-associated genetic variants on the behavior of brain cells, called microglia. Recent discoveries regarding the genetic underpinnings of Alzheimer's disease (AD), suggest that microglial cells are believed to play a key role in resistance to or susceptibility in developing AD and other neurodegenerative diseases.

According to statistics from the Alzheimer's Association, AD currently affects more than 5 million people in the U.S., and results in an estimated $259 billion cost to the nation. Over 16 million Americans are predicted to be living with Alzheimer's by 2050, which would have an estimated $1.1 trillion cost to the U.S.

Under the two-year agreement, Eisai's immuno-dementia discovery research team at its Andover innovative Medicines (AiM) Institute will work with principal investigator Tsuneya Ikezu, M.D., Ph.D., Professor of Pharmacology & Experimental Therapeutics and Neurology at Boston University School of Medicine, to study the functional impact of AD-associated genetic variants on microglial biology. Dr. Ikezu's lab has extensive experience in the cell biology of microglia, and has studied how the innate aspect of the central nervous system (CNS) influences the pathology and progression of neurodegenerative disease. He recently received the Alzheimer's Association's Inge Grundke-Iqbal Award for Alzheimer's Research, based on his work on microglia and exosome-mediated tau propagation.

"Microglia are the latest brain cell types of intense investigation at both basic and translational neuroscience research levels, and their genetic association with Alzheimer's disease is only strengthened by report after report. Development of cellular platform to study microglia biology is essential for the research community and R&D in the industry," said Dr. Ikezu.

Eisai has extensive experience in the AD area, having spent over 33 years working on the development of potential treatments, including Donepezil, the first compound found to show improvements on cognitive clinical scales, such as the Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-cog) and Clinician's Interview-based Impression of Change with caregiver input (CIBIC+). The company's current clinical pipeline, which includes a number of compounds targeting AD, can be found here.

The AiM Institute, located within the greater Boston biotech hub, is a dedicated R&D discovery innovation unit of over 90 scientists focused on delivering novel and targeted therapeutics that are validated by human genetics and related human biology data. AiM brings extensive expertise in innate immunity, complex synthetic chemistry, and an emphasis on integrated genomics and data science in its efforts to develop compounds targeting immune mechanisms in dementia.

"Human genetics provide a tremendous opportunity to discover and develop innovative and impactful new medicines. AiM is dedicated to harnessing this opportunity to improve and enhance the lives of patients with Alzheimer's disease," said Nadeem Sarwar, President of the AiM Institute. "This collaboration provides an extremely exciting opportunity to work with Boston University School of Medicine, whose world-class expertise in neurology and genetics will assist us in this mission."

The goal of the collaboration is to understand the mechanisms underlying known genetic drivers of microglial malfunction, which are believed to play a central role in the pathogenesis of AD dementia. Utilizing information attained from the study, the parties hope to develop tools for understanding microglial biology and dissect the functional impact of microglially expressed proteins. Such discoveries may accelerate innovative therapeutic drug development for AD.
