Concomitant iGlarLixi and Sodium-Glucose Co-transporter-2 Inhibitor Therapy in Adults with Type 2 Diabetes: LixiLan-G Trial and Real-World Evidence Results

Introduction: iGlarLixi, the once-daily fixed-ratio combination of insulin glargine 100 U/ml and lixisenatide, robustly improves glycaemic control in adults with type 2 diabetes irrespective of previous treatment [oral antihyperglycaemic drugs (OADs), basal insulin or glucagon-like peptide-1 receptor agonists (GLP-1 RAs)]. Sodium-glucose co-transporter-2 inhibitors (SGLT2is) are a recommended treatment option for people with type 2 diabetes with cardiovascular disease, kidney disease and/or heart failure because of their cardio- and renoprotective benefits. Herein, we assessed the effects of concomitant iGlarLixi and SGLT2i therapy. Methods: We conducted subgroup analyses according to SGLT2i use in: (1) adults with suboptimally controlled type 2 diabetes on GLP-1 RAs and OADs switching to iGlarLixi in the 26-week LixiLan-G randomised controlled trial (RCT; NCT02787551) and (2) adults switching to or adding iGlarLixi in a 6-month, retrospective real-world evidence (RWE) observational study using data from the US Optum-Humedica electronic medical records database. Changes in HbA1c and hypoglycaemia prevalence and event rates were assessed. Results: There were no major differences in baseline characteristics for those who initiated iGlarLixi while already using SGLT2i (n = 346) and those initiating iGlarLixi without concomitant SGLT2i therapy (n = 1285). HbA1c reductions from baseline to time of assessment and hypoglycaemia prevalence and event rates were similar for iGlarLixi users regardless of SGLT2i therapy. Conclusion: Evidence from an RCT and an RWE analysis supports the efficacy/effectiveness and safety of iGlarLixi when used concomitantly with SGLT2i. Trial Registration: NCT02787551.
