GLP1R and chronic kidney disease: It is unknown if shorter acting GLP-1 RA have an impact on Ao-PWV and if this may explain the discordance observed in GLP-1RA CVOTs.<h4>Materials and methods</h4>We studied people with type 2 diabetes and CKD in a proof-of-concept single centre, randomised, double-blind parallel-group placebo-controlled study that evaluated 24 weeks' treatment with lixisenatide as compared to placebo on the primary endpoint of Ao-PWV.<h4>Results</h4>In total, 101 participants (male 66%) were randomised of whom 90 were eligible for analyses (lixisenatide [n = 47] and placebo [n = 43]).
