Semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), confers kidney protection in people with type 2 diabetes (T2D) and chronic kidney disease (CKD) by improving kidney hemodynamics and stabilizing fibrosis. Sodium-glucose cotransporter-2 inhibitors (SGLT2is) represent a distinct drug class with established nephroprotective effects, mediated by hemodynamic mechanisms including reductions in glomerular hyperfiltration. Although both drug classes lower blood glucose levels, emerging evidence suggests that their kidney-protective mechanisms are largely independent and potentially additive. We hypothesized that semaglutide exerts kidney hemodynamic effects irrespective of background SGLT2i therapy. Therefore, we evaluated some kidney-protective effects of semaglutide 1.0 mg stratified by SGLT2i use.
The study is a post-hoc analysis of the REMODEL trial (NCT04865770). Adults with T2D, estimated glomerular filtration rate (eGFR) of 30-75 mL/min/1.73 m2, and urine albumin-creatinine ratio (UACR) 20-<5000 mg/g were randomized 2:1 to once-weekly semaglutide subcutaneous 1.0 mg (n=71) or placebo (n=35) for 52 weeks and stratified by concomitant treatment with SGLT2i. Kidney oxygenation (R2*) was assessed by blood oxygenation level dependent magnetic resonance imaging (BOLD-MRI), while mean global kidney perfusion (GKP), renal artery resistive index (RARI), and cortical and medullary estimates of fibrosis (diffusion weighted imaging for the apparent diffusion coefficient [ADC]) were assessed by phase-contrast MRI measured arterial flow.
At baseline, SGLT2i users and non-users exhibited similar eGFR-creatinine, though UACR was higher among SGLT2i users (Table 1). The effect of semaglutide to reduce RARI was observed in both SGLT2i users and non-users (p-interaction [p-int]=0.29). SGLT2i use did not impact the increase in cortical ADC or delta ADC observed with semaglutide vs placebo, reflecting stabilized fibrosis or lack of progression in both groups (p-int=0.73 and p-int=0.53, respectively). The ratio of cortical R2* and medullary R2* from baseline to week 52 in semaglutide and placebo groups did not differ significantly between SGLT2i users vs non-users (p-int=0.88 and p-int=0.84, respectively). There was a trend toward a higher GKP in the semaglutide group vs placebo, with similar effects in SGLT2i users and non-SGLT2i users (p-int=0.42).
In REMODEL, semaglutide had similar effects to reduce RARI and mitigate fibrosis irrespective of background SGLT2i therapy. The combination of semaglutide treatment with SGLT2i use may confer additional kidney benefits.
