January 29, 2021 Investor Relations

The new Prescription Drug User Fee Act (PDUFA) action date set by the FDA is June 7, 2021

CAMBRIDGE, Mass. and TOKYO, Jan. 29, 2021 (GLOBE NEWSWIRE) -- Biogen (Nasdaq: BIIB) and Eisai Co., Ltd. (Tokyo, Japan) today announced that the U.S. Food and Drug Administration (FDA) has extended the review period by three months for the Biologics License Application (BLA) for aducanumab, an investigational treatment for Alzheimer’s disease. The updated Prescription Drug User Fee Act (PDUFA) action date is June 7, 2021.

As part of the ongoing review, Biogen submitted a response to an information request by the FDA, including additional analyses and clinical data, which the FDA considered a Major Amendment to the application that will require additional time for review.

“We are committed to working with the FDA as it completes its review of the aducanumab application,” said Michel Vounatsos, Chief Executive Offer at Biogen. “We want to thank the FDA for its continued diligence during the review.”

Biogen submitted the aducanumab BLA to the FDA in July 2020. The FDA accepted the BLA in August 2020 and granted Priority Review.

About Aducanumab

Aducanumab (BIIB037) is an investigational human monoclonal antibody studied for the treatment of Alzheimer’s disease. Based on clinical data from patients with Mild Cognitive Impairment due to Alzheimer’s disease and mild Alzheimer’s disease, 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 disease.

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.

About Alzheimer’s Disease

Alzheimer’s disease is a progressive neurological condition that impairs thinking, memory and independence, leading to premature death. The disease is a growing global health crisis, affecting those living with the disease and their families. According to the World Health Organization (WHO), tens of millions of people worldwide live with Alzheimer’s disease, and the number will grow in the years ahead, outpacing the healthcare resources needed to manage it and costing billions of dollars.

Alzheimer’s disease is characterized by changes in the brain, including the abnormal accumulation of toxic amyloid beta plaque, which begins approximately 20 years before patients exhibit symptoms of the disease. Mild Cognitive Impairment due to Alzheimer’s disease is one of the earliest stages of the disease when symptoms start to be more visible and can be detected and diagnosed. Current research efforts are focused on catching and treating patients as early as possible for the best chance of slowing or stopping the progression of Alzheimer’s disease.
