Biogen Inc. (Nasdaq: BIIB) has submitted the final study protocol for the confirmatory Phase 4 ENVISION trial to the U.S. Food and Drug Administration (FDA) for review and approval.
- Confirmatory trial’s completion is expected in an accelerated timeline of four years with patient screening to start in May
- Multiple strategies in place to enroll patients that are representative of diverse American population
CAMBRIDGE, Mass., March 30, 2022 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) has submitted the final study protocol for the confirmatory Phase 4 ENVISION trial to the U.S. Food and Drug Administration (FDA) for review and approval. This is in line with the company’s commitment to accelerate the timelines for the trial, including submitting the final study protocol to the FDA in March 2022, as previously announced. Biogen expects the first patient to enter screening in May 2022 and the trial’s primary completion approximately four years after the study begins.
The confirmatory ENVISION trial is a requirement based on FDA’s accelerated approval of ADUHELM® (aducanumab-avwa) 100 mg/mL injection for intravenous use in early Alzheimer’s disease (Mild Cognitive Impairment due to Alzheimer’s disease and mild Alzheimer’s disease).
The study, as previously announced, will be a global, placebo-controlled trial, aiming to enroll around 1,500 patients with early Alzheimer’s disease and confirmation of amyloid beta pathology.
The company has also reaffirmed the trial’s goal of recruiting at least 18 percent of patients in the U.S. from Black/African American and Latino communities.
“Our unwavering commitment is to ensure that the trial is completed swiftly and that the diversity of patients in it reflects that of Americans diagnosed with early Alzheimer’s disease,” said Samantha Budd Haeberlein, Ph.D., SVP, Head of Neurodegeneration Development at Biogen. “We plan to work hand-in-hand with underrepresented communities and Alzheimer’s disease groups to achieve our diversity and inclusion goal.”
To increase participation among historically underrepresented patients, Biogen is leveraging multiple initiatives and working with several community groups, such as the National Minority Quality Forum and others who have expertise and a commitment in helping to overcome traditional enrollment barriers for diverse populations. These efforts are being addressed by three key strategies:
- Selecting sites with diverse staff, located in communities of color, with access to diverse patient populations;
- Supporting trial sites in identification, outreach, and engagement of underrepresented communities; and
- Engaging with community and patient organizations to increase Alzheimer’s disease awareness, education, and access to research.
The primary endpoint for the trial will be measured by the Clinical Dementia Rating–Sum of Boxes (CDR-SB) at 18 months, as announced in January 2022. The trial will also include a planned long-term extension to collect treatment data for up to 48 months.
Secondary endpoints include changes in Amyloid Positron Emission Tomography (PET) and Tau PET, as well as the Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-Cog 13), Alzheimer’s Disease Cooperative Study - Activities of Daily Living Inventory - Mild Cognitive Impairment Version (ADCS-ADL-MCI), Integrated Alzheimer’s Disease Rating Scale (iADRS), Mini-Mental State Examination (MMSE) and Neuropsychiatric Inventory (NPI-10).
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.
From 2017 to March 13, 2022, Biogen and Eisai jointly collaborated on the development, commercialization and manufacturing of ADUHELM. Effective March 14, 2022, Biogen has sole decision-making authority over the development, commercialization and manufacturing of ADUHELM. In 2022 the parties will continue in a global profit/loss sharing arrangement subject to a cap on Eisai’s expenses for 2022. Eisai will be entitled to a tiered royalty on net sales of ADUHELM as of January 1, 2023.
