Abstract

It is believed that glycogen synthase kinase‐3 hyperphosphorylates tau protein in progressive supranuclear palsy (PSP). The Tau Restoration on PSP (TAUROS) trial assessed the glycogen synthase kinase‐3 inhibitor tideglusib as potential treatment. For the magnetic resonance imaging (MRI) substudy reported here, we assessed the progression of brain atrophy. TAUROS was a multinational, phase 2, double‐blind, placebo‐controlled trial in patients with mild‐to‐moderate PSP who were treated with oral tideglusib (600 mg or 800 mg daily) or with placebo for 1 year. A subset of patients underwent baseline and 52‐week MRI. Automated, observer‐independent, atlas‐based, and mask‐based volumetry was done on high‐resolution, T1‐weighted, three‐dimensional data. For primary outcomes, progression of atrophy was compared both globally (brain, cerebrum) and regionally (third ventricle, midbrain, pons) between the active and placebo groups (Bonferroni correction). For secondary outcomes, 15 additional brain structures were explored (Benjamini & Yekutieli correction). In total, MRIs from 37 patient were studied (placebo group, N = 9; tideglusib 600 mg group, N = 19; tideglusib 800 mg group, N = 9). The groups compared well in their demographic characteristics. Clinical results showed no effect of tideglusib over placebo. Progression of atrophy was significantly lower in the active group than in the placebo group for the brain (mean ± standard error of the mean: −1.3% ± 1.4% vs. −3.1% ± 2.3%, respectively), cerebrum (−1.3% ± 1.5% vs. −3.2% ± 2.1%, respectively), parietal lobe (−1.6% ± 1.9% vs. −4.1% ± 3.0%, respectively), and occipital lobe (−0.3% ± 1.8% vs. −2.7% ± 3.2%, respectively). A trend toward reduced atrophy also was observed in the frontal lobe, hippocampus, caudate nucleus, midbrain, and brainstem. In patients with PSP, tideglusib reduced the progression of atrophy in the whole brain, particularly in the parietal and occipital lobes. © 2014 International Parkinson and Movement Disorder Society

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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

  • Clinical studies in patients with mild-to-moderate AD or PSP treated with tideglusib were negative on clinical outcomes.

    “The clinical studies in patients with mild-to-moderate AD (NCT01350362, NCT00948259) or PSP (NCT01049399) patients treated with tideglusib were negative on the clinical outcomes [218]; however, a subgroup analysis of PSP patients showed reduced brain atrophy [219].”

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.
