Abstract

BACKGROUND: The ARGO study was a phase II, double-blind, placebo controlled, four parallel arm trial of tideglusib in Alzheimer's disease (AD). OBJECTIVE: To prove the clinical efficacy of an inhibitor of glycogen synthase kinase-3 (GSK-3), in AD. METHODS: Mild to moderate (Mini-Mental State Examination (MMSE) score, 14-26) AD patients on cholinesterase inhibitor and/or memantine treatment were administered tideglusib or placebo for 26 weeks. The ADAS-cog15 was the primary efficacy measure; function, cognition, behavior, and quality of life were assessed as secondary measures; cerebral atrophy in MRI and the levels of tau, amyloid-β, and BACE1 in cerebrospinal fluid (CSF) were exploratory endpoints. RESULTS: 306 AD patients were randomized to active (1000 mg QD: n = 86, 1000 mg QOD: n = 90, and 500 mg QD: n = 50) or placebo (n = 85) in 55 sites in four European countries. There were no statistically significant differences between either active and placebo arms in the efficacy variables. However, BACE1 in CSF significantly decreased with treatment in a small subgroup of patients. Participants with mild AD in the 500 mg QD group showed significant responses on ADAS-cog15, MMSE, and word fluency. Diarrhea (14-18% in active, 11% placebo) and dose-dependent, mild to moderate, and fully reversible transaminase increase (9-16% in active, 3.5% placebo) were the most frequent adverse events. CONCLUSIONS: Short term (26 weeks) tideglusib was acceptably safe but produced no clinical benefit in this trial. However, given the non-linear dose response, especially in mildly affected patients, further dose finding studies in early disease stages and for longer duration are warranted to examine GSK-3 inhibition in AD patients.

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.
