Abstract

Background: This study aimed to analyse data from two different studies (phase II and phase III) regarding the safety and efficacy of treatment with alum formulated glutamic acid decarboxylase GAD 65 (GAD‐alum) at 30 months after administration to children and adolescents with type 1 diabetes. Methods: The phase II trial was a double‐blind, randomised placebo‐controlled study, including 70 children and adolescents who were followed for 30 months. Participants received a subcutaneous injection of either 20 µg of GAD‐alum or placebo at baseline and 1 month later. During a subsequent larger European phase III trial including three treatment arms, participants received two or four subcutaneous injections of either 20 µg of GAD‐alum and/or placebo at baseline, 1, 3 and 9 months. The phase III trial was prematurely interrupted at 15 months, but of the 148 Swedish patients, a majority completed the 21 months follow‐up, and 45 patients completed the trial at 30 months. Both studies included GAD 65 auto‐antibodies‐positive patients with fasting C‐peptide ≥0.10 nmol/l. We have now combined the results of these two trials. Results: There were no treatment related adverse events. In patients treated with 2 GAD‐alum doses, stimulated C‐peptide area under the curve had decreased significantly less (9 m: p < 0.037; 15 m: p < 0.032; 21 m: p < 0.003 and 30 m: p < 0.004), and a larger proportion of these patients were also able to achieve a peak stimulated C‐peptide >0.2 nmol/L (p < 0.05), as compared with placebo. Conclusion: Treatment with two doses of GAD‐alum in children and adolescents with recent‐onset type 1 diabetes shows no adverse events and preserves residual insulin secretion.

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.
