Biogen to Present New Research at the International Conference on Alzheimer's and Parkinson's Diseases (AD/PD 2022)

CAMBRIDGE, Mass., March 11, 2022 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) announced the company will present new Alzheimer's disease research, as well as data for ADUHELM^® (aducanumab-avwa) injection 100 mg/mL for intravenous use, at the upcoming International Conference on Alzheimer's and Parkinson's Diseases (AD/PD 2022), taking place March 15-20 in Barcelona, Spain and virtually. These data include analyses of treatment effect on biomarkers of Alzheimer's disease in the long-term extension studies, with over two years of Phase 3 data.

An invited plenary lecture, "Key Milestones in Alzheimer's Disease" on March 16, will include an examination of the ability of ADUHELM to reduce amyloid beta plaque and plasma p-tau181, and the relationship between these biomarkers and clinical endpoints during the long-term extension phase of the ADUHELM clinical program.

An oral presentation on March 18, "Effect of Reduction in Brain ?-Amyloid Levels on Cognitive Decline in Randomized Clinical Trials: An Updated Instrumental Variable Meta-Analysis," will discuss the details of a meta-analysis on the causality between reduction of amyloid beta levels and reduction of cognitive decline in randomized clinical trials.

About ADUHELM^® (aducanumab-avwa) injection 100 mg/mL for intravenous use
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).

ADUHELM is a monoclonal antibody directed against amyloid beta. The accumulation of amyloid beta plaques in the brain is a defining pathophysiological feature of Alzheimer's disease. The accelerated approval of ADUHELM has been granted based on data from clinical trials showing the effect of ADUHELM on reducing amyloid beta plaques, a surrogate biomarker that is reasonably likely to predict clinical benefit, in this case a reduction in clinical decline.

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. Although most people 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. ADUHELM can also cause serious allergic reactions. The most common side effects of ADUHELM include: swelling in areas of the brain, with or without small spots of bleeding in the brain or on the surface of the brain (ARIA); headache; and fall. Patients should call their healthcare provider for medical advice about side effects.

As of October 2017, Biogen and Eisai Co., Ltd. are collaborating on the global co-development and co-promotion of aducanumab.
