Brief Summary

Background: Sodium-glucose-cotransporter (SGLT) inhibition has been observed to reduce risk of cardiovascular events and kidney failure in persons with type 2 diabetes. People with type 1 diabetes also have increased risk of cardiovascular and kidney disease, and may benefit from SGLT-inhibition. The exact mechanism of how SGLT-inhibition benefits the kidneys are yet unknown. Change in renal hypoxia may be a factor. Objective: The primary aim of this study is to assess the effects of 12 weeks SGLT-1 and 2 inhibition on renal oxygenation in persons with type 1 diabetes and chronic kidney disease. Further aims are to study if renal oxygen consumption and response to SGLT-inhibition differs between people of African-Caribbean or Northern European decent. Additionally effects on left ventricular ejection fraction, kidney function and biomarkers in blood and urine will be explored. Method: 12 weeks treatment with oral sotagliflozin or matching placebo as intervention. Kidney oxygenation and perfusion parameters and left ventricular ejection fraction will be assessed by functional magnetic resonance imaging. Kidney function and biomarkers will be assessed according to local hospital laboratory guidelines. Design: Randomized, double-blinded, placebo-controlled, cross over intervention study. Study population: 69 persons with type 1 diabetes and diabetic kidney disease with albuminuria will be included, 39 at Steno Diabetes Center Copenhagen, 30 at King's College London. Endpoints: Primary end-point: Change from 0 to 12 weeks in dynamic R2\*-weighted signal after treatment with sotagliflozin compared to placebo. Secondary endpoints: Change from 0 to 12 weeks with sotagliflozin compared with placebo on renal perfusion, renal artery flow, renal oxygen consumption, renal parenchymal triglyceride fraction, renal fibrosis, left ventricular ejection fraction, urinary albumin-creatinin ratio, ketone bodies, erythropoietin, pro brain natriuretic peptide, and plasma- and urine inflammation- and fibrosis biomarkers as well as difference after 12 weeks treatment in glomerular filtration rate. Timeframe: Inclusion of patients from february 2024. Last visit september 2025. Presentation spring 2026, publication fall 2026.
