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” and “Partnerships aimed at expanding access to medicines.”

Eisai will continue to make effective use of partnerships as we endeavor to fully satisfy patients' needs around the world.
