GLP-1 drugs have reshaped how chronic kidney disease is approached in patients with type-2 diabetes and obesity. The FLOW trial gave semaglutide a CKD outcomes label, and the REMODEL trial — presented at the 2026 World Congress of Nephrology — added mechanistic data showing that semaglutide decreased renal fat, lowered arterial resistance, and stabilized cortical fibrosis. Biopsies revealed reduced immune cells around glomeruli, and transcriptomic analysis identified glomerular endothelial cells as the most responsive cell type.
The story has expanded: GLP-1s now have heart, kidney, and metabolic indications often pursued in the same patient. Cardiometabolic peptide candidates outside the GLP-1 class — Takeda's rusfertide for polycythemia vera, Merck's PCSK9 work — also land here.

A Frontiers in Endocrinology multicenter retrospective cohort study (2026) reports real-world safety and effectiveness of semaglutide in patients with type 2 diabetes and end-stage renal disease — the population systematically excluded from FLOW (which capped at eGFR ≥ 25) and the SELECT pre-specified kidney composite analysis. ESRD patients comprise roughly 1% of the diabetic population but 7% of US healthcare spending; their cardiovascular event rates are among the highest documented. The cohort fills a clinical gap: prescribers managing dialysis-dependent patients have had to extrapolate from outcome trials that explicitly excluded the population. Work joins the SOUL oral-semaglutide CKD analysis as the fastest-growing GLP-1 evidence stream beyond obesity and T2D.
Mechanistic data from the REMODEL trial presented at the 2026 World Congress of Nephrology showed semaglutide decreased renal fat, lowered arterial resistance, and stabilized cortical fibrosis. Biopsies revealed reduced immune cells around glomeruli, and transcriptomic analysis identified glomerular endothelial cells as the most responsive cell type to treatment.
The FLOW trial showed semaglutide reduced major kidney disease events by ~24%, while the SELECT trial found a 20% reduction in major adverse cardiovascular events among 17,600+ adults.
At APhA2026, semaglutide's FLOW trial showed 24% reduction in major kidney events in CKD patients, while tirzepatide's SURMOUNT-OSA trial demonstrated dramatic reductions in sleep apnea severity.
