Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, ¡°Eisai¡±) announced today that it has entered into a business alliance agreement for exclusive development and commercialization of a cognitive function test – Cogstate Brief Battery (CBB) – developed by Cogstate Ltd. (Headquarters: Australia, ¡°Cogstate¡±), in Japan as a digital tool for self-assessment of cognitive function (classified as miscellaneous goods).

The CBB consists of four tests, each measuring different cognitive domains: psychomotor function, attention, working memory, and learning, and it has been developed and already in use as a digital tool for self-assessment of cognitive function overseas, including the United States.

Eisai will aim to raise awareness of cognitive function by developing and making widely available the CBB in Japan jointly with Cogstate as a simpler digital tool for self-assessment of cognitive function, which can be used at various locations such as at home and community events. With this tool, it is expected to have opportunities to review lifestyle and to consult with specialists and primary care physicians by objectively checking the changes in cognitive function. It is important to note that this tool is not an alternative for medical examination and diagnosis by qualified medical professionals.

In its medium-term business plan, EWAY2025, Eisai is aiming to become a ¡°Medico Societal Innovator¡± (a company that changes society through creating medicines and providing solutions), promoting various kinds of digitalization such as the analysis of big data, including using real world data to develop an environment for early diagnosis and initiation of treatment and provision of solutions. This also includes creating next-generation treatments primarily in ¡°neurology¡± and ¡°oncology¡± that are Eisai¡¯s therapeutic areas of focus. Through these efforts to partner with Cogstate to develop and make widely available the CBB as a digital tool for self-assessment of cognition more easily in Japan where aging is progressing and to raise awareness of cognitive function, Eisai aims to contribute to the realization of well-being.
