WOODCLIFF LAKE, N.J., July 22, 2021 /PRNewswire/ -- Eisai Inc., the U.S. pharmaceutical subsidiary of Eisai Co., Ltd., announced today the presentation of findings from the company’s robust Alzheimer’s disease (AD) pipeline, including lecanemab (BAN2401). Recently granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA), 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. Data and research from Eisai’s rich dementia pipeline, including joint assets with Biogen, will be featured in 18 oral and poster presentations at the 2021 Alzheimer’s Association International Conference (AAIC), July 26-30, 2021 in Denver, Colorado and virtually.

  • A lecanemab late-breaker oral presentation will report a preliminary assessment of the investigational compound’s clinical effects from the open label extension phase 2 proof of concept study in early AD.
  • Eisai’s Deputy Chief Clinical Officer Michael Irizarry, M.D., MPH will present findings from an evaluation of the longitudinal plasma Aβ 42:40 ratio and the relationship to longitudinal brain amyloid PET SUVr in the core and open label extension of the Phase 2 proof of concept study following treatment with lecanemab in subjects with early AD.
  • Another oral presentation will feature preliminary screening and baseline characteristics of the lecanemab Phase 3 clinical AHEAD 3-45 study for preclinical AD.

“The lecanemab data and information Eisai and Biogen will present at AAIC 2021 is particularly relevant given that the U.S. Food and Drug Administration recently granted lecanemab Breakthrough Therapy designation,” said Ivan Cheung, Chairman, Eisai Inc. and Global President, Neurology Business Group, Eisai Co., Ltd. “The momentum behind Eisai’s growing Alzheimer’s disease franchise and the accelerated approval of Eisai and Biogen’s ADUHELM is exciting. In March 2021, Eisai and Biogen completed enrollment of 1,795 patients with early Alzheimer’s disease in our Phase 3 Clarity AD clinical study and the Phase 3 clinical study, AHEAD 3-45, is currently exploring lecanemab in individuals with preclinical Alzheimer’s disease.”

  • An oral presentation regarding the clinical study design of the Dominantly Inherited AD (DIAD) Trial of Eisai’s investigational MTBR (microtubule binding region) targeted anti-tau antibody E2814 will be given. E2814 was 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.

  • A poster presentation will be given on the results of in vivo study of E2511, Eisai’s investigational novel synapse re-generating small compound tropomyosin receptor kinase A (TrkA) allosteric modulator.

  • Biogen Inc. will make five presentations about our joint asset ADUHELM™ (aducanumab-avwa) 100 mg/mL solution for injection, including an oral presentation about the design of ICARE AD-US, a prospective, single-arm, multicenter, noninterventional real-world study of aducanumab in the US.

    ADUHELM was granted accelerated approval by the US FDA on June 7, 2021. ADUHELM is indicated for the treatment of Alzheimer’s disease. Treatment with ADUHELM should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in Aβ plaques observed in patients treated with ADUHELM. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s). Please see full Prescribing Information, including the Medication Guide.

“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. At Eisai, our goal is to serve patients by transforming the current symptom-based framework to one where biomarkers become a core component of diagnosis, prognosis and therapeutic decision-making,” said Harald Hampel, M.D., Ph.D., Vice President, Chief Medical Officer, Neurology Business Group, Eisai Inc. “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.”

Virtual Symposium

Eisai and Biogen will hold a virtual symposium, “Defining the next-generation clinical care pathway for Alzheimer’s disease: biological, technological, and healthcare perspectives.” As the AD treatment landscape evolves, it is critical to transform the AD patient journey from a symptoms-based approach to a next-generation biomarker-guided and technology-enabled clinical care pathway. Esteemed faculty will review the latest advances and challenges in the integration of in vivo biomarkers and emerging digital tools into the larger healthcare ecosystem for AD. Featured speakers will include:

  • Jeffrey Cummings, MD, ScD
  • Wiesje van der Flier, PhD
  • Rhoda Au, PhD, MBA
  • Soeren Mattke, MD, DSc

The symposium will be held in-person and virtually Monday, July 26, 2021, 11:30 a.m. - 12:45 p.m. Mountain Daylight Time and will be available online 30 days following AAIC 2021. Onsite attendees may participate live at the Colorado Ballroom in the Hilton Denver City Center.

INDICATION and IMPORTANT SAFETY INFORMATION

INDICATION

ADUHELM is indicated for the treatment of Alzheimer’s disease. Treatment with ADUHELM should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with ADUHELM. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).

IMPORTANT SAFETY INFORMATION

What is the most important information a patient should know about ADUHELM?
ADUHELM can cause serious side effects including: Amyloid Related Imaging Abnormalities or “ARIA”. ARIA is a common side effect that does not usually cause any symptoms but can be serious. It is most commonly seen as temporary swelling in areas of the brain that usually resolves over time. Some people may also have small spots of bleeding in or on the surface of the brain with the swelling. Although most people with swelling in areas of the brain do not have symptoms, some people may have symptoms such as: headache, confusion, dizziness, vision changes, and nausea. The patient’s healthcare provider will do magnetic resonance imaging (MRI) scans before and during treatment with ADUHELM to check for ARIA. Patients should call their healthcare provider or go to the nearest hospital emergency room right away if they have any of the symptoms listed above.

Before receiving ADUHELM, patients should tell their healthcare provider about all of their medical conditions, including if: they are pregnant or plan to become pregnant or are breastfeeding or plan to breastfeed. It is not known if ADUHELM will harm their unborn baby or if aducanumab-avwa (the active ingredient in ADUHELM) passes into breast milk.

What are the possible side effects of ADUHELM? ADUHELM can cause serious side effects, including: See above “What is the most important information a patient should know about ADUHELM? Serious allergic reactions. Swelling of the face, lips, mouth, or tongue and hives have happened during an ADUHELM infusion. Patients should tell their healthcare provider if they have any of the symptoms of a serious allergic reaction during or after an ADUHELM infusion.

The most common side effects of ADUHELM include: swelling in areas of the brain, with or without small spots of bleeding in or on the surface of the brain (ARIA); headache and fall. Patients should call their healthcare provider for medical advice about side effects. Patients may report side effects to FDA at 1-800-FDA-1088.
