Biogen to Present Data at Virtual 2020 Alzheimer’s Association International Conference Highlighting Comprehensive Approach to Alzheimer’s Disease

CAMBRIDGE, Mass., July 24, 2020 (GLOBE NEWSWIRE) -- Biogen (Nasdaq: BIIB) today announced there will be multiple data presentations from its Alzheimer’s disease (AD) clinical development portfolio, a virtual satellite symposium and AD PACE poster presentations at the Alzheimer’s Association International Conference (AAIC), which will be held online July 27-31. The company’s contributions to AAIC showcase its work to build a broad AD franchise across multiple targets and modalities, as well as to advance knowledge about early diagnosis, unmet patient needs and health system capacity to diagnose and treat people living with AD.

Biogen’s AD portfolio of investigational assets includes aducanumab, an investigational treatment that, if approved, could meaningfully change the course of the disease. At the conference, Biogen will share an encore platform presentation of the previously reported topline results from the aducanumab Phase 3 EMERGE and ENGAGE studies. No new data from the studies are included in the encore presentation, which will be pre-recorded and followed by a live, virtual question and answer (Q&A) session. This presentation and Q&A session will be held on Wednesday, July 29, 7:00 am – 8:00 am Central Daylight Time (CDT) as part of Developing Topic Session: Developments in Clinical Trials and Cognitive Assessment (SO3-02). To access the presentation and Q&A session, please complete a free registration for AAIC in advance at aaic2020.vfairs.com/en/register. The presentation and Q&A session will be held in the Live Auditorium on the AAIC platform and can be accessed from either aaic2020.vfairs.com or the Investor’s section of Biogen’s website at investors.biogen.com. Following the webcast, an archived version will be available on the Investor’s section of Biogen’s website.

In addition, Biogen’s drug candidates and research will be featured in a platform presentation about the Phase 2 TANGO study to evaluate gosuranemab (BIIB092) in patients with early AD; a poster about the feasibility of clinical research studies reported by patients with behavioral variant frontotemporal dementia and their caregivers; and a poster on tau protein interactions. Conference activities also include a virtual satellite symposium about early diagnosis and readying the health system for the potential entry of a disease-modifying treatment for AD.

Posters and presentations will be available for 30 days on the AAIC conference website.

About Aducanumab
Aducanumab (BIIB037) is an investigational human monoclonal antibody studied for the treatment of Alzheimer’s disease. Based on clinical data, aducanumab has the potential to impact underlying disease pathophysiology, slow cognitive and functional decline and provide benefits on patients’ ability to perform activities of daily living, including conducting personal finances, performing household chores, such as cleaning, shopping and doing laundry, and independently traveling out of the home. If approved, aducanumab would be the first treatment to meaningfully change the course of the disease for individuals living with Alzheimer’s.

Biogen licensed aducanumab from Neurimmune under a collaborative development and license agreement. Since October 2017 Biogen and Eisai have collaborated on the development and commercialization of aducanumab globally.

EMERGE and ENGAGE were Phase 3 multicenter, randomized, double-blind, placebo-controlled, parallel-group studies designed to evaluate the efficacy and safety of aducanumab. The primary objective of the studies was to evaluate the efficacy of monthly doses of aducanumab as compared with placebo in reducing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) score. Secondary objectives were to assess the effect of monthly doses of aducanumab as compared to placebo on clinical decline as measured by the Mini-Mental State Examination (MMSE), Alzheimer’s Disease Assessment Scale-Cognitive Subscale 13 Items (ADAS-Cog 13) and Alzheimer’s Disease Cooperative Study-Activities of Daily Living Inventory Mild Cognitive Impairment Version (ADCS-ADL-MCI).

About BAN2401
BAN2401 is a humanized monoclonal antibody for Alzheimer’s disease (AD) that is the result of a strategic research alliance between Eisai and BioArctic. BAN2401 selectively binds to neutralize and eliminate soluble, toxic Aß aggregates that are thought to contribute to the neurodegenerative process in AD. As such, BAN2401 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 BAN2401 for the treatment of AD pursuant to an agreement concluded with BioArctic in December 2007. Currently, a global clinical Phase 3 study (Clarity AD) of BAN2401 in early AD is underway. BAN2401 is being jointly developed by Eisai and Biogen Inc. The National Institute on Aging, a division of the National Institutes of Health, is providing funding for the A45 Study (grant number R01AG061848) and A3 Study (grant number R01AG054029).

About Gosuranemab
Gosuranemab (BIIB092) is a humanized monoclonal antibody that targets N-terminal tau. Gosuranemab is currently being evaluated in the Phase 2 TANGO study in participants with mild cognitive impairment due to Alzheimer’s disease or with mild Alzheimer’s disease. Biogen licensed gosuranemab from Bristol-Myers Squibb Company.
