July 18, 2018 at 11:30 AM UTC
  • Ongoing Alzheimer’s disease research programs target possible causes of the disease through multiple modalities
  • Data to be presented from Alzheimer’s disease clinical development portfolio including aducanumab, elenbecestat, and BAN2401  
  • Data underscore Biogen’s long-term commitment to furthering Alzheimer’s disease research and treatment, with a focus on patients with early stage disease

CAMBRIDGE, Mass., July 18, 2018 (GLOBE NEWSWIRE) -- Biogen (Nasdaq:BIIB) announced it will present data from its Alzheimer’s disease clinical development portfolio at the upcoming Alzheimer’s Association International Conference (AAIC) in Chicago (July 22-26). Data being presented are part of Biogen’s research programs targeting several of the identified causes of Alzheimer’s disease, focusing on early-stage disease.

“The data to be presented at AAIC exemplify our belief that treatments are needed at the earliest stages of Alzheimer’s disease to impact the underlying pathophysiology and delay disease progression,” said Samantha Budd Haeberlein, vice president, clinical development at Biogen. “We are pleased to present new findings at this year’s meeting and continue to demonstrate our commitment to the millions of people living with Alzheimer’s disease.”

Biogen presentations will include a new analysis from the Phase 1b (PRIME) study of aducanumab, an investigational anti-amyloid beta antibody therapy for mild cognitive impairment (MCI) due to Alzheimer’s disease and mild dementia due to Alzheimer’s disease. Aducanumab is currently being evaluated in two global Phase 3 studies, ENGAGE and EMERGE, which are designed to evaluate its safety and efficacy in slowing cognitive and functional impairment in people with MCI due to Alzheimer’s disease and mild Alzheimer’s disease dementia, and is being co-developed with Eisai as of October 2017.

In addition, Biogen’s collaborator Eisai will present topline Phase 2 clinical study results of BAN2401, an anti-amyloid beta protofibril antibody, and data on elenbecestat, a BACE (beta amyloid cleaving enzyme) inhibitor. Elenbecestat is currently being evaluated in two global Phase 3 clinical studies (MISSION AD 1/2) in early Alzheimer’s disease.

About Aducanumab
Aducanumab (BIIB037) is an investigational compound being studied for the treatment of early Alzheimer’s disease. Aducanumab is a human recombinant monoclonal antibody (mAb) derived from a de-identified library of B cells collected from healthy elderly subjects with no signs of cognitive impairment or cognitively impaired elderly subjects with unusually slow cognitive decline using Neurimmune’s technology platform called Reverse Translational Medicine (RTM). Biogen licensed aducanumab from Neurimmune under a collaborative development and license agreement. As of October 22, 2017, Biogen and Eisai Co. Ltd. are collaborating on the development and commercialization of aducanumab globally. In addition, the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for the development of aducanumab, a process allowing priority reviews by the FDA for drugs deemed as having potential to treat serious conditions and tackle key unmet medical needs.

About BAN2401
BAN2401 is a humanized monoclonal antibody for Alzheimer’s disease that is the result of a strategic research alliance between Eisai and BioArctic. BAN2401 selectively binds to neutralize and eliminate soluble, toxic Aβ aggregates that are thought to contribute to the neurodegenerative process in Alzheimer’s disease. 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 Alzheimer’s disease pursuant to an agreement concluded with BioArctic in December 2007. In March 2014, Eisai and Biogen entered into a joint development and commercialization agreement for BAN2401 and the parties amended that agreement in October 2017.

About Elenbecestat
Elenbecestat is an oral BACE (beta amyloid cleaving enzyme) inhibitor currently being investigated in Phase 3 clinical studies for Alzheimer’s disease discovered by Eisai and in collaboration with Biogen. By inhibiting BACE, a key enzyme in the production of Aβ peptides, elenbecestat reduces Aβ production, which is thought to lead to a reduction in amyloid plaque formations caused by the aggregation of toxic oligomers and protofibrils in the brain. Currently, two global Phase 3 clinical studies (MISSION AD1/2) of elenbecestat in early Alzheimer’s disease including mild cognitive impairment (MCI) due to AD/Prodromal AD and the early stages of mild AD are underway.  In addition, the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for the development of elenbecestat, a process to facilitate development and expedite review by FDA for drugs deemed as having potential to treat serious conditions and addressing unmet medical needs.
