Our Locations
A breakthrough is a team effort that demands passion, perseverance and bold innovation at every stage; from discovery to delivery. Across the U.S., visionaries, strategists, scientists, researchers, technologists and operations specialists work as one to transform ideas into meaningful solutions for patients, their caregivers and loved ones.
It Starts with Strategic Vision
Located in Nutley, NJ, our hhceco Center serves as the U.S. Corporate Headquarters for our fully integrated pharmaceutical business, with a strategic focus on neurology and oncology. At this center, we identify critical medical challenges where we can make the greatest impact, set clear priorities, allocate resources and foster a culture of innovation.
The Journey Leads to the Frontiers of Research & Development
At the Eisai Center for Genetics Guided Dementia Discovery (G2D2) in Cambridge, MA, leading experts in human genetics, data science and precision chemistry work together to accelerate the discovery of breakthrough immunodementia precision therapies.
Beyond Discovery
At Eisai, we believe it isn’t a breakthrough until patients actually benefit. That’s why manufacturing, testing and distribution are just as vital to our innovation as research and development.
Exton Campus
At this vibrant innovation hub, we develop, manufacture and test biologics targeting cancers or neurodegenerative diseases.
The 60,000-square-foot Exton Research Building is a hub for a wide range of biologic therapeutic research and development within Deep Human Biology Learning (DHBL). Activities at the site include antibody generation and engineering, analytical and process development, chemistry, manufacturing and controls (CMC) program management, analytical outsourcing, Development Quality Assurance (DQA), Product Quality (PQ) and essential site support functions such as IT, Facilities, HR and Training.
Our 60,000-square-foot, LEED-certified Biologics Pilot Plant plays a critical role in manufacturing and testing biologic drug substances—complex medicines derived from living organisms—for use in preclinical and clinical studies. Equipped with 2,000L and 1,000L bioreactors, the facility is currently undergoing upgrades to support the future commercialization of novel biologic therapies.
The 216 Warehouse Building is our state-of-the-art storage facility, supporting research, manufacturing and development by housing a wide range of materials and equipment essential to our studies and operations.
Additional Manufacturing and Logistics Centers
Our Baltimore, MD, facility reflects our commitment to meeting patients’ unmet medical needs. It plays a vital role in ensuring global access to a specialized implant used in the treatment of a rare form of brain cancer.
Our Raleigh, NC, facility is home to specialists who manage global logistics and oversee external manufacturing partners. While we prioritize making our own medicines, we strategically outsource when it leads to a better outcome for patients, because putting patients first guides every decision we make.
