Eisai Alzheimer's Disease Pipeline Research to be Presented at Virtual AD/PD™ 2021, Including Lecanemab (BAN2401) Data
- Oral presentations and posters highlighting Eisai's investigational novel therapies and immunoassay system being studied for Alzheimer's disease and its clinical symptoms
- Preliminary analyses evaluating brain amyloid beta reduction with lecanemab to be featured in oral presentation
- Virtual symposium: The Science Behind the Aβ Pathway in Alzheimer's Disease
WOODCLIFF LAKE, N.J., March 5, 2021 /PRNewswire/ -- Eisai Inc., the U.S. pharmaceutical subsidiary of Eisai Co., Ltd., announced today the presentation of data and information from the company's robust Alzheimer's disease (AD) pipeline, including lecanemab (BAN2401). Jointly developed by Eisai and Biogen Inc., lecanemab is an investigational humanized monoclonal antibody that binds to neutralize and eliminate soluble, toxic amyloid beta (Aβ) aggregates (protofibrils) that are thought to contribute to the neurodegenerative process in AD. This data will be among Eisai's many presentations at AD/PD™ 2021 Virtual Conference, the 15th International Conference on Alzheimer's and Parkinson's Diseases, March 9 - 14, 2021.
"Alzheimer's disease is a progressively debilitating and devastating neurodegenerative disease. The focus on Alzheimer's disease has historically been on alleviating cognitive and behavioral symptoms, but there has been significant progress in understanding the biological mechanisms of the disease through the science of biomarkers. We look forward to sharing data and discussing the scientific rationale that the amyloid beta pathway plays a key role in the pathophysiology of Alzheimer's disease," said Harald Hampel, M.D., Ph.D., Vice President, Chief Medical Officer, Neurology Business Group, Eisai Inc., who was recently named one of the world's top five Alzheimer's disease experts by Expertscape based on objective ranking of his contribution and impact on the Alzheimer's field through scientific publications.

- About Lecanemab (BAN2401)
Lecanemab is an investigational humanized monoclonal antibody for Alzheimer's disease that is the result of a strategic research alliance between Eisai and BioArctic. Lecanemab selectively binds to neutralize and eliminate soluble, toxic Aβ aggregates (protofibril) that are thought to contribute to the neurodegenerative process in AD. As such, lecanemab may have the potential to have an effect on disease pathology and to slow down the progression of the disease. Eisai obtained the global rights to study, develop, manufacture and market lecanemab for the treatment of AD pursuant to an agreement concluded with BioArctic in December 2007. In March 2014, Eisai and Biogen entered into a joint development and commercialization agreement for lecanemab and the parties amended that agreement in October 2017.
Currently, lecanemab is being studied in a pivotal Phase 3 clinical study in symptomatic early AD (Clarity-AD), following the outcome of the Phase II clinical study (Study 201). In July of 2020, the Phase III clinical study (AHEAD 3-45) for individuals with preclinical AD, meaning they are clinically normal and have intermediate or elevated levels of amyloid in their brains, was initiated. AHEAD 3-45 is conducted as a public-private partnership between the Alzheimer's Clinical Trial Consortium, funded by the National Institute on Aging, part of the National Institutes of Health, and Eisai.
- About the Joint Development between Eisai and Biogen for Alzheimer's Disease
Eisai and Biogen are collaborating on the joint development and commercialization of AD treatments. Biogen serves as the lead in the co-development of aducanumab and Eisai serves as the lead in the co-development of lecanemab, anti-amyloid beta (Aβ) protofibril antibodies, and the companies plan to pursue marketing authorizations for aducanumab and lecanemab worldwide. If approved, the companies will also co-promote aducanumab and lecanemab in major markets, such as the United States, the European Union and Japan. Both companies will equally split overall costs, including research and development expenses. Eisai will book all sales for lecanemab following marketing approval and launch, and profits will be equally shared between the companies.
- About the Collaboration between Eisai and BioArctic for Alzheimer's Disease
Since 2005, BioArctic has had a long-term collaboration with Eisai regarding the development and commercialization of drugs for the treatment of AD. The commercialization agreement on the lecanemab antibody was signed in December 2007, and the development and commercialization agreement on the antibody lecanemab back-up for AD, which was signed in May 2015. Eisai is responsible for the clinical development, application for market approval and commercialization of the products for AD. BioArctic has no development costs for lecanemab in AD.
- About E2027
Discovered by Eisai, E2027 is a selective phosphodiesterase (PDE) 9 inhibitor. Inhibiting PDE9 reduces the degradation of cyclic GMP (cGMP) which is critical to signal transmission among cells, and helps maintain the concentration of cGMP in the brain. Eisai is currently developing E2027 as a new treatment for dementia with Lewy bodies.
- About the Collaboration between Eisai and Sysmex
Eisai and Sysmex have entered into a comprehensive non-exclusive collaboration agreement aimed at the creation of new diagnostics in the field of dementia in February 2016. Leveraging each other's technologies and knowledge, the two companies aim to discover next-generation diagnostics that will enable early diagnosis, selection of treatment options and the regular monitoring of the effects of treatment for dementia.
