Global Partners

Horizontal Collaborations with Global Partners

Although Otsuka independently discovers new drugs, we also value working with our global partners in horizontal collaborations. We prefer partnerships of equals (horizontal collaborations) supported by candid and frequent discussions, whereas major pharmaceutical companies more commonly pursue corporate acquisitions and outright purchase of promising drug candidates (vertical approach.)
