Amyloid β-based therapy for Alzheimer’s disease: challenges, successes and future
Open accessAbstract
Amyloid β protein (Aβ) is the main component of neuritic plaques in Alzheimer’s disease (AD), and its accumulation has been considered as the molecular driver of Alzheimer’s pathogenesis and progression. Aβ has been the prime target for the development of AD therapy. However, the repeated failures of Aβ-targeted clinical trials have cast considerable doubt on the amyloid cascade hypothesis and whether the development of Alzheimer’s drug has followed the correct course. However, the recent successes of Aβ targeted trials have assuaged those doubts. In this review, we discussed the evolution of the amyloid cascade hypothesis over the last 30 years and summarized its application in Alzheimer’s diagnosis and modification. In particular, we extensively discussed the pitfalls, promises and important unanswered questions regarding the current anti-Aβ therapy, as well as strategies for further study and development of more feasible Aβ-targeted approaches in the optimization of AD prevention and treatment.
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
This review argues that Aβ accumulation remains a central driver of AD and that recent anti-Aβ successes—including FDA approval of aducanumab and lecanemab—have revived the amyloid cascade hypothesis. It summarizes Aβ biology, biomarkers, and anti-Aβ drug development while outlining persistent challenges such as insufficient specificity, inadequate animal models, late treatment, and loss of physiological Aβ functions.
Key findings
- Of 298 AD therapies in clinical trials (ALZFORUM, March 2023), 76 target Aβ or its aggregates; 38 were discontinued due to ineffectiveness or toxic side effects, and two antibody-based drugs—aducanumab and lecanemab—have been approved by the FDA.
- Lecanemab’s Phase 3 trial reduced cognitive and functional decline as measured by CDR-SB by 27% versus placebo; ARIA occurred in around 21% of lecanemab-treated individuals versus just over 9% of placebo controls. Donanemab’s partial Phase 3 results showed a 35% slowing of cognitive and functional decline, with 47% of treated participants showing no clinical progression at 1 year versus 29% on placebo.
- BACE1 inhibitors and γ-secretase inhibitors/modulators largely failed or were discontinued because of toxicity, lack of substrate specificity, or insufficient efficacy; examples include LY2886721, atabecestat, elenbecestat, lanabecestat, umibecestat, avagacestat, and several γ-secretase modulators.
- Soluble Aβ at physiological levels has reported functions including enhancement of LTP, stimulation of neuronal differentiation, promotion of injury recovery, antimicrobial activity, tumor suppression, antioxidant effects, neurogenesis, and maintenance of BBB integrity, so therapies should ideally target fibrils, protofibrils, or oligomers while preserving normal Aβ monomers.
Methods
- Narrative review; no systematic review protocol, search strategy, or formal evidence appraisal is stated.
- Sources include published literature and clinical trial registries, specifically ALZFORUM (March 2023) and clinicaltrials.gov (accessed March 19, 2023), plus cited references.
- Main analysis is a narrative synthesis of the amyloid cascade hypothesis, Aβ aggregation and pathological roles, Aβ-based biomarkers, anti-Aβ therapies, challenges, and future directions.
Limitations
- The paper states that anti-Aβ therapy faces disturbed physiological functions of soluble Aβ, insufficient specificity (e.g., γ-secretase and BACE1 off-target effects), lack of accurate animal models, and late application relative to biomarker onset.
- It states that current animal models mainly mimic familial AD and cannot fully reflect late-onset sporadic AD complexity, including aging, human immune differences, and extensive neuronal loss.
- Evident from the text: as a narrative review, it does not describe systematic search or selection criteria, quality appraisal, or quantitative synthesis; conclusions rely on author interpretation of the cited literature.

The Discussion (page unavailable) says the 52–97-year age range belongs to Moreno-Jimenez et al. (2019), whereas this paper’s participants were 79–99. It also says that, unlike Moreno-Jimenez et al., this study did not observe a correlation between neurogenesis and amyloid deposition or neurofibrillary tangles. Its reported decline concerns DCX+PCNA+ cells in people with mild cognitive impairment, not DCX-positive cells declining with neuropathological progression in the claimed cohort. (LLM, conf=0.90)

“Both genetic (e.g., ApoE4, TREM2) and non-genetic (e.g. diabetes, obesity, stroke, or physical inactivity) risk factors for late-onset sporadic Alzheimer’s disease (SAD) have also been identified to increase Aβ generation and/or reduce Aβ clearance for its accumulation.4,41–45”

The paper’s main text (page unavailable) reports that ageing, type-2-diabetes models and stroke models upregulate CLU, and concludes that CLU inhibits Aβ degradation and promotes Aβ generation. It does not establish that the cited examples ApoE4, TREM2, obesity or physical inactivity act through those mechanisms; its mention of AD-associated CLU variants does not establish the genetic part of the claim.

The Introduction identifies ApoE ε4 as a genetic risk factor for AD, and the paper reports that apoE affects soluble Aβ metabolism in mice. It does not establish that ApoE4 reduces Aβ clearance, or address TREM2 or the listed non-genetic risk factors.

The Introduction states that the APP gene is on chromosome 21 and is overexpressed in trisomy 21. It also says that most Down syndrome patients over 40 develop classical Alzheimer’s neuropathology, including amyloid-bearing plaques and neurofibrillary tangles; this age qualification matters because the changes develop over time.

“In addition, both synthetic and endogenous Aβ42 monomers in nanomolar concentrations stimulated the activity of cyclic adenosine monophosphate (cAMP) responsive element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF), which possessed key roles in the regulation of gene expressions related to neuronal functions and survival in normal brains.371,372”

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.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
