Switching to iGlarLixi versus continuation of a daily or weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) in insufficiently controlled type 2 diabetes: A LixiLan-G trial subgroup analysis by HbA1c and GLP-1 RA use at screening.

Abstract

AimIn people with type 2 diabetes (T2D) requiring intensification beyond glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) and oral antihyperglycaemic drugs (OADs), switching to iGlarLixi was shown to be efficacious and well‐tolerated in the LixiLan‐G trial. This exploratory analysis of LixiLan‐G assessed the efficacy and safety of switching to iGlarLixi versus continuing GLP‐1 RA therapy, stratified by screening HbA1c level (≥7.0 to ≤7.5 %; >7.5 to ≤8.0 %; >8.0 to ≤9.0 % [≥53 to ≤58 mmol/mol; >58 to ≤64 mmol/mol; >64 to ≤75 mmol/mol]) and previous GLP‐1 RA regimen at screening (once/twice daily or once weekly).Materials and MethodsEndpoints for all subgroups included: change in HbA1c, achievement of HbA1c <7 % and hypoglycaemia events. Adverse events and changes in fasting plasma glucose (FPG), 2‐hour postprandial plasma glucose (PPG), 2‐hour PPG excursion and weight were analysed according to previous GLP‐1 RA regimen.ResultsSwitching to iGlarLixi in all subgroups resulted in significantly greater reductions in HbA1c and proportions of participants reaching HbA1c <7 % (including with no documented hypoglycaemia) at Week 26 compared with continued GLP‐1 RA treatment. Switching to iGlarLixi also led to significantly greater reductions in FPG, 2‐hour PPG, and 2‐hour PPG excursion, irrespective of previous GLP‐1 RA regimen. Rates of hypoglycaemia were low, but slightly higher in those who switched to iGlarLixi for all subgroups. Modest weight gain was seen with iGlarLixi, irrespective of previous GLP‐1 RA regimen.ConclusionsSwitching to iGlarLixi improved glycaemic control, regardless of screening HbA1c or previous GLP‐1 RA type, offering a simple, efficacious and well‐tolerated treatment intensification option for people with T2D inadequately controlled by GLP‐1 RAs and OADs.
