An overview of GLP-1 agonists and recent cardiovascular outcomes trials
Open accessAbstract
Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are emerging as an important therapy to consider for patients with type 2 diabetes (T2D) given this class of treatment's ability to reduce glycated haemoglobin and their associated weight loss and low risk for hypoglycaemia. Additionally, seven cardiovascular outcomes trials (CVOTs) have been performed in the past 4 years using lixisenatide, liraglutide, semaglutide, exenatide, albiglutide, dulaglutide and oral semaglutide. All have found non-inferiority for cardiovascular outcomes, with many finding superiority of these drugs. These findings have transformed our guidelines on pharmacological treatment of T2D. This review article will discuss GLP-1 RA therapy, review the seven CVOTs reported to date and discuss the implications on current guidelines and therapies going forward.

In the citing paper
“Trials in people with type 2 diabetes have shown convincing reductions in cardiovascular events with some GLP-1 RA (259); whether these benefits would also be seen in people with type 1 diabetes is unknown.”
In the citing paper
“In recent years, seven trials have demonstrated their superiority or almost non-inferiority for CV outcomes, indicating advantageous cardio-protective effects [170].”

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.
