A comparison of the effects of tirzepatide and dulaglutide on major kidney events in people with type 2 diabetes: pre-specified exploratory analyses of the SURPASS-CVOT trial.

BACKGROUND: In the SURPASS-CVOT trial, tirzepatide, a dual incretin agonist that targets the glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors, was shown to be non-inferior to dulaglutide for the primary composite cardiovascular outcome in people with type 2 diabetes and atherosclerotic cardiovascular disease. Here, we report the results of a pre-specified exploratory analysis of SURPASS-CVOT that aimed to assess major kidney events in the overall population, low-to-moderate-risk chronic kidney disease population, and high-risk chronic kidney disease population. METHODS: or initiation of chronic kidney replacement therapy), or death from kidney disease. FINDINGS: [0·65 to 1·22], p<0·0001). Nausea, vomiting, and diarrhoea were all more common in those receiving tirzepatide than in those receiving dulaglutide. INTERPRETATION: Among people with type 2 diabetes and atherosclerotic cardiovascular disease, tirzepatide was associated with a reduced risk of major kidney events compared with dulaglutide, primarily driven by a reduction in new-onset macroalbuminuria in people with low-to-moderate-risk chronic kidney disease, and slowed decline in kidney function in people with high-risk chronic kidney disease.
