Eisai To Present Latest Data On Alzheimer's Disease / Dementia Pipeline At The 11th Clinical Trials On Alzheimer's Disease (CTAD) Conference
Additional Data from BAN2401 Phase 2 Results to be Presented

WOODCLIFF LAKE, N.J., Oct. 17, 2018 /PRNewswire/ -- Eisai Inc., the U.S. pharmaceutical subsidiary of Eisai Co., Ltd., announces today that five oral and two poster presentations from its Alzheimer's disease pipeline, including additional data on the BAN2401 Study 201 results, will be highlighted at the 11th Clinical Trials on Alzheimer's Disease (CTAD) conference, October 24-27, 2018 in Barcelona, Spain. 

The presentations will highlight three investigational compounds that are being jointly developed by Eisai and Biogen Inc.: BAN2401 and aducanumab, both anti-Aβ antibodies, and elenbecestat, a BACE inhibitor. Data will also be presented on lemborexant, an investigational compound that is being jointly developed by Eisai and Purdue Pharma.

Eisai and Biogen previously announced results from BAN2401 Study 201 during the Alzheimer's Association International Conference (AAIC) in July. Additional BAN2401 data will be presented at the symposium, "Clinical and Biomarker Updates from BAN2401 Study 201 in Early AD," and will be webcast live on October 25. To access the live webcast, please visit https://www.eisai.com/ir/index.html.

There will be an oral elenbecestat presentation which will include additional data on Study 202 results that were initially presented in July 2018 at AAIC in patients with mild cognitive impairment and mild-to-moderate Alzheimer's disease. Elenbecestat is currently being investigated in two ongoing Phase 3 clinical studies, MISSION AD1/2 in patients with early Alzheimer's disease.

Two aducanumab late-breaking presentations, an oral and a poster, will also be shared by Biogen, as well as cumulative safety data from the Phase 1b PRIME long-term extension study of patients with prodromal and mild Alzheimer's disease, which is being conducted by Biogen. Currently, Eisai and Biogen are advancing aducanumab in two Phase 3 clinical studies, ENGAGE and EMERGE.

Eisai and Purdue Pharma will also present preliminary results from a first-in-kind Phase 2 Study 202 of lemborexant – a dual orexin receptor antagonist under development for the treatment of sleep/wake regulation – for Irregular Sleep-Wake Rhythm Disorder (ISWRD) in patients with mild-to-moderate Alzheimer's dementia.

"It is our dedicated research and development team, robust pipeline and successful 30-year legacy in Alzheimer's disease that fuels our commitment to help meet the diverse health care needs of patients living with this devastating disease," said Ivan Cheung, Chairman & CEO, Eisai Inc. "With these emerging data, our hope is that we will be able to accelerate our efforts toward breaking new ground in Alzheimer's disease, relentlessly."
