Alzheimer's disease failed clinical trials

Asher, Shreya, Priefer, Ronny·2022·Life Sciences

Abstract

Alzheimer's disease is a progressive neurodegenerative disease typically presenting with symptoms of memory loss and cognitive decline. Existing theories for the causation of this focuses on amyloid beta plaques and neurofibrillary tau tangles. Most US Food and Drug Administration approved therapies for Alzheimer's disease target cognitive function. A multitude of clinical trials, with a variety of different targets have been conducted over the decades which have focused on the two clinical signs, with the only success being the controversial 2021 approval of an IgG1 anti-Ab antibody targeting the clearance of the Aβ plaques. Presented is a review of all previously failed Alzheimer's disease clinical trials and the rationale for their failures.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Second-generation anti-amyloid antibodies solanezumab, gantenezumab, and crenezumab failed to improve cognitive functions for mild and moderate Alzheimer's disease in several clinical trials.

    “Second-generation anti-amyloid antibody against soluble monomeric Aβ (solanezumab), insoluble monomeric Aβ (gantenezumab), and monoclonal antibody against multiple Aβ forms (crenezumab) failed to have efficacy in improving cognitive functions for mild and moderate AD in several clinical trials (Table 2, for example [36]).”

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.
