Effect of the dual sodium-glucose co-transporter-1 and-2 inhibitor sotagliflozin on renal outcomes in type 1 diabetes and type 2 diabetes: A systematic review and meta-analysis of randomized controlled trials

AimTo investigate the renal safety profile of sotagliflozin, a novel sodium-glucose co-transporter-1 and -2 inhibitor, in patients with type 1 diabetes and type 2 diabetes, with or without renal impairment, as well as its efficacy in decreasing the risk of further renal events, with an emphasis on those with previous renal impairment.MethodsEmbase, Medline, CENTRAL and Scopus were searched from their inception until 24 April 2023 for randomized controlled trials that reported estimated glomerular filtration rate (eGFR), urinary albumin excretion or composite renal events (CRE). The Cochrane risk of bias 2 tool was used. Mean difference, relative risk (RR) and 95% confidence intervals were estimated (PROSPERO: CRD42023425583).ResultsFourteen studies were included in this review (n = 17 574 participants; intervention n = 9312, control n = 8262). The median follow-up was 24.5 (Q1 = 15.25, Q3 = 28) months. Four studies recruited participants with renal impairment; baseline eGFR ranged from 23.8 to 50.5 mL/min/1.73m2. The change in eGFR for studies (n = 6) with a follow-up of 52 weeks or longer was -1.23 (-1.45, -1.01) mL/min/1.73m2. Sotagliflozin did not significantly alter urinary albumin excretion. No change was observed in the risk of CRE (n = 6 studies; RR = 0.82 [0.61, 1.12]), including in participants with renal impairment. High risk of bias was a limitation of this review.ConclusionsSotagliflozin did not adversely affect renal function or change the risk of key renal outcomes, including for participants with pre-existing renal impairment. Therefore, sotagliflozin was safe; however, further research is needed to determine its efficacy in reducing the risk of diabetic kidney disease.
