  • ICARE AD-US is an observational real-world phase 4 study designed to evaluate the safety and effectiveness of ADUHELM in clinical practice

  • ICARE AD-US is one of three programs to generate post-approval data on ADUHELM, including the re-dosing Phase 3b EMBARK study and the planned confirmatory Phase 4 post-marketing requirement study

  • Biogen aims to enroll at least 16 percent Latinx and Black/African American patients with Alzheimer’s disease in the ICARE AD-US study as part of its commitment to increase participation from traditionally underrepresented communities

CAMBRIDGE, Mass., July 29, 2021 (GLOBE NEWSWIRE) -- Biogen (Nasdaq: BIIB) and Eisai Co., Ltd. (Tokyo) today announced that Biogen led a late-breaking presentation on the design of the first real-world observational Phase 4 study in Alzheimer’s disease called ICARE AD-US, at the Alzheimer’s Association International Conference (AAIC), being held both virtually and in Denver, Colo. from July 26 – 30, 2021. ICARE AD-US, a prospective study of ADUHELM™ (aducanumab-avwa) 100 mg/mL solution for injection, is designed to collect real-world, long-term effectiveness and safety data on ADUHELM. The virtual oral session (#57522) was titled, “ICARE AD-US: design of a prospective, single-arm, multicenter, noninterventional real-world study of aducanumab in United States.”

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).

ICARE AD-US is a real-world study that will provide information on the long-term effectiveness and safety of ADUHELM as prescribed in routine clinical practice in the U.S. based on the label approved by the U.S. Food and Drug Administration (FDA). The primary objective of the study is to characterize and evaluate real-world, long-term changes in cognition, function and neuropsychiatric status in ADUHELM-treated patients. Secondary objectives are related to gaining a better understanding of ADUHELM safety in real-world clinical practice.

The study design includes an important goal to help address the common underrepresentation of Black/African American and Latinx patients in Alzheimer’s disease studies, aiming to enroll at least 16 percent of the trial’s expected 6,000 participants from these communities. Alzheimer’s disease clinical trials commonly have one to two percent enrollment from these groups, even though Black/African Americans and Latinx people are respectively two and one-and-a-half times more likely than older White Americans to have Alzheimer’s disease.

The study intends to enroll patients with Alzheimer’s disease over four years from approximately 200 sites in the U.S. Patients will be monitored for a period of up to five years.

“Biogen is committed to both generating new data about ADUHELM and supporting steps to bring adequate representation to this trial and other clinical trials from traditionally underrepresented groups,” said Ivana Rubino, Ph.D., U.S. and Global Head of Medical, Alzheimer’s Disease at Biogen. “We believe this can help us better understand the safety and effectiveness of treatment in patients with Alzheimer’s disease across ethnicities, something that has challenged researchers in this field for decades. The ICARE AD-US study, designed in collaboration with Alzheimer’s disease experts, underscores both of these commitments.”

The ICARE AD-US study is one of three clinical programs designed to generate new data about ADUHELM. The others include EMBARK, the ongoing, Phase 3b re-dosing study for eligible patients previously enrolled in ADUHELM clinical trials, including the PRIME long-term extension, EMERGE and ENGAGE, and the confirmatory Phase 4 trial that is in the process of being designed and will be conducted to verify the clinical benefit of ADUHELM as part of the post-marketing requirements associated with the accelerated approval pathway of ADUHELM in the U.S.

“The ICARE AD-US study will provide important information on the safety, effectiveness and management of Alzheimer’s disease with ADUHELM, the first approved treatment for Alzheimer’s disease that targets the amyloid pathway, in the real-world setting across diverse populations,” said Harald Hampel, M.D., Ph.D., Vice President, Chief Medical Officer, Neurology Business Group, Eisai Inc. “It is important for Eisai and the larger scientific community to recruit patients of diverse ethnicities for clinical trials to help address health disparities.”

The presentation on the ICARE AD-US study will be available for 30 days on the AAIC conference website. Biogen will also post the presentation on the investors section of its website at investors.biogen.com.

About ADUHELM™ (aducanumab-avwa) injection 100 mg/mL solution

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).

Aducanumab-avwa 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.
