Eisai to Present New Lecanemab Data, Including Research Evaluating Safety Profile, Clinical Outcomes and Quality of Life Measures, as Well as Other Important Alzheimer’s Disease Research, at the AD/PD 2023 Annual Meeting

TOKYO, Mar 23, 2023 – (JCN Newswire) – Eisai Co., Ltd. announced today the company will present the latest findings on lecanemab (generic name, U.S. brand name: LEQEMBI), Eisai’s anti-amyloid beta (Aβ) protofibril* antibody for the treatment of Alzheimer’s disease (AD), at the 2023 International Conference on Alzheimer’s and Parkinson’s Diseases and related neurological disorders (AD/PD) from March 28-April 1 in Gothenburg, Sweden and virtually. Eisai will present new findings from the company’s large, global Phase III confirmatory study of lecanemab, Clarity AD, including research into the management and monitoring of amyloid-related imaging abnormalities (ARIA) and health-related quality of life (HRQoL) measures. Eisai will also host a symposium, titled “Patient Clinical Care Pathway in Alzheimer’s disease: Dialogue Amongst Experts,” which will address the evolving landscape in AD. The lecanemab data and additional research findings from Eisai’s AD portfolio will be featured in 11 presentations, including seven oral and four poster presentations.

“Our latest research examines the real-world outcomes based on lecanemab’s impact on clinical results and safety, including its effect on health-related quality of life. Through our ongoing research, we hope to help simplify the patient journey and improve the lives of those living with Alzheimer’s disease,” said Michael Irizarry, M.D., Deputy Chief Clinical Officer and Senior Vice President of Clinical Research at Eisai Inc. “In addition to lecanemab, Eisai is presenting on several other key issues that will shape the future of Alzheimer’s disease and brain health, including the next generation of clinical care and diagnostic pathways, exploration of unique populations affected by the disease, and accelerating drug development. We look forward to sharing our latest findings, including new insights from Eisai’s Clarity AD trial of lecanemab, with the scientific community at AD/PD 2023.”
