Abstract

Aducanumab is a novel disease-modifying anti-amyloid-beta (Aβ) human monoclonal antibody specifically targeted to the pathophysiology of Alzheimer's disease (AD). It was granted for treating AD in June 2021 by the United States Food and Drug Administration. We systematically analyzed available trials to evaluate the efficacy and safety of aducanumab treating AD. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. We conducted an extensive literature search using the electronic databases MEDLINE through PubMed, EMBASE, Cochrane, Web of Science, and Scopus for suitable studies on aducanumab. We considered human clinical trials of aducanumab, assessing its efficacy and adverse effects in treating AD, excluding any experimental animal studies. We included three randomised controlled trials. Studies reported that aducanumab reduced brain amyloid-beta plaques in a time- and dose-dependent manner (dose-response, P < 0.05) and a slowed decline in cognition (22% reduction) in the high-dose treated group, difference of -0.39 versus placebo in Clinical Dementia Rating Scale Sum Boxes (95% CI, -0.69 to -0.09; P = 0.012) along with a reduced amyloid positron emission tomography standard uptake value ratio score (P < 0.001) and plasma p181-tau (phosphorylated tau) level. Amyloid-related imaging abnormality was reported as a serious adverse event and was profound in high-dose treated group (425/1029 in 10 mg/kg). Aducanumab has been reported to affect two main pathophysiologic hallmarks (Aβ and tau) of AD. We suggest future studies addressing aducanumab's efficacy and safety to confirm that the benefit of this drug outweighs the risk.

  • Reduction in amyloid-beta brain plaques and encouraging clinical outcomes in one of two pivotal Phase III trials were factors cited for aducanumab's expedited approval.

    “The reduction in amyloid-beta brain plaques, a purported surrogate endpoint that indicates the “progression” of AD, and the encouraging clinical outcomes in one of the two pivotal Phase III trials were two of the factors cited for aducanumab’s expedited approval [130,134,135,136].”
  • Aducanumab is the first disease-modifying medication for AD, a recombinant monoclonal antibody targeting amyloid beta specifically, and functions by lowering amyloid deposits or brain plaques.

    “The first disease-modifying medication for AD is a recombinant monoclonal antibody called aducanumab, also known by the brand name Aduhelm. It targets amyloid beta specifically [37]. It functions by lowering the quantity of amyloid deposits or brain plaques [130,131].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
