BIOGEN INC. - ADUHELM continued to reduce two key Alzheimer’s disease pathologies, amyloid beta plaques and p-tau181, in patients treated for up to two and a half years
- Data from both Phase 3 studies also show that clinical decline was reduced in participants who had plasma p-tau181 reduction at 78 weeks
- These data further inform the scientific evidence for amyloid as a surrogate biomarker and the importance of continuation of treatment
Data from the long-term extension study showed that ADUHELM significantly reduced amyloid beta plaque levels out to Week 132. The data also showed that ADUHELM continued to decrease plasma p-tau181 levels at 128 weeks. Patients with more effective amyloid beta clearance (SUVR lower than 1.1 by 78 weeks) also had greater decreases in p-tau181 at week 128. These findings point to the potential of continued benefit of treatment in the longer term with continued reduction of amyloid beta plaques.
“These are meaningful findings, which further our understanding of amyloid and downstream biomarkers, such as p-tau 181, in Alzheimer’s disease and can help inform how long patients may benefit from treatment to reduce amyloid beta plaque,” said
Data showed that patients with a reduction in plasma p-tau181, an exploratory endpoint, had less clinical progression across all four clinical endpoints (CDR-SB, MMSE, ADAS-Cog13, and ADCS-ADL-MCI) measuring cognition and function in both Phase 3 trials at Week 78.
In the placebo-controlled period of the Phase 3 trials, the incidence of ARIA-E in the 10 mg/kg group was 35.2%. The incidence was higher among APOE ε4 carriers (43.0%) than non-carriers (20.3%). While the majority of ARIA is asymptomatic, serious symptoms in the setting of ARIA can occur (0.3% of participants in the 10 mg/kg group of the Phase 3 trials. Most events (98.2%) of ARIA-E resolved on study, with the majority resolving within 12-16 weeks. Biogen is committed to continuing to work with the aim that ARIA is further characterized and that the risk of ARIA is well understood.

These latest data are part of Biogen’s ongoing commitment to generate additional clinical data to further characterize and understand ADUHELM’s profile and engage with the scientific community. Additional research data was presented at AD/PD, along with multiple presentations describing various aspects of ADUHELM’s clinical program.
About ADUHELM® (aducanumab-avwa) 100 mg/mL injection 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.
