Abstract

Aim: To investigate whether combined treatment with empagliflozin (a sodium‐glucose cotransporter‐2 inhibitor) and semaglutide (a glucagon‐like peptide‐1 receptor agonist) can reduce urinary albumin‐creatinine ratio (UACR) compared to treatment with empagliflozin alone in individuals with type 2 diabetes (T2D) and albuminuria. Methods: We conducted a randomized, placebo‐controlled, double‐blind, parallel study including 60 individuals with T2D and albuminuria. All participants initiated open‐label empagliflozin 25 mg once daily, on top of renin‐angiotensin system inhibition, in a run‐in period of 26 weeks. Subsequently, participants were randomized to semaglutide or placebo 1 mg once weekly for 26 weeks. The primary endpoint was change in UACR. Secondary endpoints were change in: (i) measured glomerular filtration rate (GFR); (ii) 24‐hour systolic blood pressure; (iii) glycated haemoglobin (HbA1c) level; (iv) body weight; and (v) plasma renin and aldosterone levels. Results: Addition of semaglutide to empagliflozin provided no additional change in UACR from randomization to end‐of‐treatment. The mean (95% confidence interval) difference in UACR was –22 (–44; 10)% ( P = 0.15) between treatment groups. Neither GFR, 24‐hour blood pressure, body weight, nor plasma renin activity was changed with semaglutide. HbA1c (–8 [–13; –3] mmol/mol; P = 0.003) and plasma aldosterone (–30 [–50; –3] pmol/L; P = 0.035) were reduced with semaglutide compared to placebo. Conclusions: Semaglutide added to empagliflozin did not change UACR, measured GFR, 24‐hour systolic blood pressure, body weight or plasma renin levels in individuals with T2D and albuminuria. Semaglutide improved glycaemic control and plasma aldosterone levels compared to placebo.

  • Several smaller short-term trials reported additive effects of GLP-1 receptor agonists and SGLT2 inhibitors on surrogate outcomes such as body weight, blood pressure and HbA1c.

    “Several smaller short-term trials reported additive effects of GLP-1 RAs and SGLT2i on surrogate outcomes such as body weight, blood pressure and HbA1c18–21.”

    From Effects of semaglutide with and without concomitant SGLT2 inhibitor use in participants with type 2 diabetes and chronic kidney disease in the FLOW trial (2024) · cites this paper as [20]

    In §3.3 (page unavailable), this 26-week trial reports an additional HbA1c reduction with semaglutide on top of empagliflozin, but no significant additional reduction in body weight. Section 3.2 likewise finds no difference in 24-hour systolic blood pressure. The paper discusses other combination trials with benefits across these outcomes, but its own results support only the HbA1c part of the claim. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
