¾«¶«Ó°Òµ. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that the company will conduct a total of 11 presentations, including the latest data of the investigational anti-amyloid beta (Aβ) protofibril antibody lecanemab (development code: BAN2401) for which the U.S. Food and Drug Administration has granted Breakthrough Therapy designation, at the Alzheimer’s Association International Conference (AAIC) to be held in Denver, Colorado and virtually from July 26 to 30, 2021.
Major presentations regarding lecanemab include oral presentations about the preliminary assessment of the clinical effect of lecanemab following 18 months of treatment in the open-label extension of the Phase 2b proof of concept study (201 study) in subjects with early Alzheimer’s disease (AD) and preliminary screening and baseline characteristics of the Phase 3 clinical study, AHEAD 3-45, for preclinical AD will be given. In addition, an oral presentation regarding the design of the clinical study for the investigational MTBR targeted anti-tau antibody E2814, which has been selected by the Dominantly Inherited Alzheimer Network Trials Unit “DIAN-TU” as the first investigational medicine among anti-tau drugs for the DIAN-TU tau study, will be given. A poster presentation will also be given on the results of an in vivo study of E2511, Eisai’s in-house discovered and developed investigational novel oral synapse regenerant. A Phase 1 study for E2511 is underway.
Additionally, ¾«¶«Ó°Òµand Biogen Inc. (Nasdaq: BIIB, Corporate headquarters: Cambridge, Massachusetts, “Biogen”) will hold a virtual symposium, “Defining the next-generation clinical care pathway for Alzheimer’s disease: biological, technological, and healthcare perspectives,” focusing on the AD treatment landscape. As the possibilities for treatment development increase, it is critical to transform the AD patient journey from a symptoms-based approach to a clinical care pathway that is guided by next-generation biomarkers and enabled with technology. Rhoda Au, Ph.D, MBA; Jeffrey Cummings, M.D, D.Sc; Soeren Mattke, M.D, D.Sc; and Wiesje van der Flier, Ph.D; four esteemed AD researchers, will review the latest advances and challenges in the integration of biomarkers and emerging digital tools into the larger healthcare ecosystem for AD.
¾«¶«Ó°Òµserves as the lead in the co-development of lecanemab, an anti-Aβ protofibril antibody, which is being jointly developed by ¾«¶«Ó°Òµand Biogen.
¾«¶«Ó°Òµaims to realize the prevention and cure of dementia through a multi-dimensional and holistic approach with a foundation of over 35 years of experience of drug discovery activities in the area of AD and dementia. ¾«¶«Ó°Òµstrives to create innovative medicines as soon as possible to further contribute to addressing the unmet medical needs of, as well as increasing the benefits provided to, those living with the disease and their families.

[Notes to editors]
- 1. About Lecanemab (development code: BAN2401)
Lecanemab is an investigational humanized monoclonal antibody for AD that is the result of a strategic research alliance between ¾«¶«Ó°Òµand BioArctic. Lecanemab selectively binds to neutralize and eliminate soluble, toxic amyloid-beta (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. ¾«¶«Ó°Òµobtained 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 ¾«¶«Ó°Òµand 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 2 clinical study (Study 201). In July 2020 the Phase 3 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. In June 2021, FDA has granted Breakthrough Therapy designation.
- 2. About E2814
An investigational anti-tau antibody, E2814 is being developed as a potential disease-modifying agent for tauopathies including sporadic AD. E2814 was discovered as part of the research collaboration between ¾«¶«Ó°Òµand University College London. E2814 is designed to prevent the spreading of tau seeds within the brains of affected individuals. Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU) has selected E2814 as the first investigational medicine among anti-tau drugs for their DIAN-TU tau study. Phase Ib/II for dominantly inherited AD has been initiated.
- 3. About E2511
E2511 is Eisai’s in-house discovered and developed investigational novel molecule that directly binds to tropomyosin receptor kinase A (TrkA); a nerve growth factor (NGF) located on the neural cell membrane. E2511 could potentially promote recovery and synaptic remodeling of damaged cholinergic neurons. A Phase 1 study for E2511 is underway.
- 4. About Lemborexant (Product name: Dayvigo® CIV)
Lemborexant, an orexin receptor antagonist, is Eisai’s in-house discovered and developed small molecule that inhibits orexin neurotransmission by binding competitively to the two subtypes of orexin receptors (orexin receptor 1 and 2). Fast on/off receptor kinetics of lemborexant to orexin receptors may influence lemborexant’s potential to facilitate improvements in sleep onset and maintenance with minimal morning residual effects.
- 5. About Aducanumab-avwa
Biogen licensed aducanumab, a human monoclonal antibody, from Neurimmune in 2007 under a collaborative development and license agreement. Since October 2017, Biogen and ¾«¶«Ó°Òµhave collaborated on the development and commercialization of aducanumab globally.
- 6. About the Collaboration between ¾«¶«Ó°Òµand Biogen for AD
¾«¶«Ó°Òµand Biogen are collaborating on the joint development and commercialization of AD treatments. ¾«¶«Ó°Òµserves as the lead in the co-development of lecanemab, an anti-Aβ protofibril antibody.
- 7. About the Collaboration between ¾«¶«Ó°Òµand BioArctic for AD
Since 2005, BioArctic has had a long-term collaboration with ¾«¶«Ó°Òµregarding 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 was signed in May 2015. ¾«¶«Ó°Òµis 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.
