Semaglutide in patients with kidney failure and obesity undergoing dialysis and wishing to be transplanted: A prospective, observational, open‐label study

AIMS: Chronic kidney disease (CKD) and obesity are major global health challenges, eventually leading to kidney replacement therapy (KRT), but body mass index (BMI) thresholds hinder kidney transplantation. Glucagon-like peptide-1 receptor agonists induce weight loss, thereby offering attractive treatment options; however, their safety and efficacy have not been systematically investigated in patients undergoing dialysis. MATERIALS AND METHODS: , were undergoing dialysis (12 haemodialysis and 1 peritoneal dialysis) and had not been listed for transplantation due to their weight. Semaglutide was administered once weekly subcutaneously, and the dose was increased from 0.25 mg to 0.5 mg and then to 1 mg. Study endpoints included change in body weight and BMI (primary - statistically evaluated by repeated measures analysis of variance [ANOVA]), side effects, adverse events, blood parameters and patient-reported outcomes (secondary). RESULTS: . At week 12, average weight reduction under semaglutide treatment was 4.6 ± 2.4 kg and ranged from 2.0 to 9.7 kg (p < 0.001 for weight and BMI reduction across the study period). One patient discontinued treatment due to nausea/vomiting, two patients died of unrelated causes and six patients reported side effects. Approximately 9 months after the treatment started, three patients were able to seriously reconsider being listed for transplantation. CONCLUSIONS: Semaglutide treatment resulted in significant reduction in weight and BMI in patients with obesity undergoing dialysis, while maintaining an acceptable side effect profile comparable to that of the non-dialysis population.
