FDA Approves Updated ADUHELM™ Prescribing Information to Emphasize Population Studied in Clinical Trials

CAMBRIDGE, Mass. and TOKYO, July 08, 2021 (GLOBE NEWSWIRE) -- Biogen (Nasdaq: BIIB) and Eisai Co., Ltd. (Tokyo, Japan) today announced the U.S. Food and Drug Administration (FDA) has approved an updated label for ADUHELM™ (aducanumab-avwa) injection 100 mg/mL solution.

The update includes an addition to the Indications and Usage section of the label (Section 1) to emphasize the disease stages studied in the clinical trials, as seen below (italics to note updated language).

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).

Alfred Sandrock, Jr., M.D., Ph.D., Head of Research and Development at Biogen, said, “Based on our ongoing conversations with prescribing physicians, FDA and patient advocates, we submitted this label update with the goal to further clarify the patient population that was studied across the three ADUHELM clinical trials that supported approval. We are committed to continue to listen to the community’s needs as clinical practice adapts to this important, first-in-class treatment option.”

The update clarifies the indication by emphasizing information about the disease stages studied in the ADUHELM clinical trials. Information about the population studied has been previously communicated by Biogen and Eisai, including in the companies’ statement of June 23, 2021.

There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied.

IMPORTANT SAFETY INFORMATION

What is the most important information a patient should know about ADUHELM?

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. It is most commonly seen as temporary swelling in areas of the brain that usually resolves over time. Some people may also have small spots of bleeding in or on the surface of the brain with the swelling. Although most people with swelling in areas of the brain 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. Patients should call their healthcare provider or go to the nearest hospital emergency room right away if they have any of the symptoms listed above.

Before receiving ADUHELM, patients should tell their healthcare provider about all of their medical conditions, including if: they are pregnant or plan to become pregnant or are breastfeeding or plan to breastfeed. It is not known if ADUHELM will harm their unborn baby or if aducanumab-avwa (the active ingredient in ADUHELM) passes into breast milk.

What are the possible side effects of ADUHELM? ADUHELM can cause serious side effects, including: See above “What is the most important information a patient should know about ADUHELM?”

Serious allergic reactions. Swelling of the face, lips, mouth, or tongue and hives have happened during an ADUHELM infusion. Patients should tell their healthcare provider if they have any of the symptoms of a serious allergic reaction during or after an ADUHELM infusion.

The most common side effects of ADUHELM include: swelling in areas of the brain, with or without small spots of bleeding in or on the surface of the brain (ARIA); headache and fall. Patients should call their healthcare provider for medical advice about side effects. Patients may report side effects to FDA at 1-800-FDA-1088.
