Eisai prioritizes patient care and access to medicines, with operations across North America including research and commercial facilities in Massachusetts, Pennsylvania, New Jersey, Maryland, and North Carolina.
Competitive Advantage
Eisai maintains a distributed U.S. research and development footprint across five states (Massachusetts, Pennsylvania, New Jersey, Maryland, and North Carolina) rather than a single hub. The company explicitly operates with a 'human health care' (hhc) philosophy that puts patients and families first before commercial considerations. Eisai allocates approximately 15% of its workforce (1,500 of 10,000 employees) to research and development activities. The company focuses on two global business groups structured as fully independent end-to-end businesses with their own discovery, development, and marketing operations.
