Eisai's Partnership Initiatives

Eisai believes that partnerships are an extremely effective means of improving business efficiency and productivity. While we engage in a diverse array of collaboration models, such partnerships can be broadly divided into “Partnerships aimed at creating innovation in therapeutic areas of focus”, “Partnerships aimed at building new business models” and “Partnerships aimed at expanding access to medicines.” Eisai will continue to make effective use of partnerships to promptly maximize contributions to patients.
