Methods: A systematic literature search identified randomized controlled trials (RCTs) comparing iGlarLixi, premix insulin or basal insulin (BI) in combination with meal-time insulin, in people inadequately controlled with BI. Eligible RCTs were compared using Bayesian network meta-analysis. Results: Eight RCTs, some open-label, involving 3538 participants, with a study duration of 24-30 weeks were included. The estimated difference in HbA1c reduction with iGlarLixi compared with premix insulin was −0.50%-units (95% credible interval: −0.93 to −0.06) with 98% probability of iGlarLixi being superior to premix. Estimates for iGlarLixi versus meal-time + BI (thrice-daily meal-time insulin + basal) and basal-plus (once-daily meal-time insulin + BI) were −0.35 (−0.89 to +0.13)%-units and −0.68 (−1.18 to −0.17)%-units with probabilities of real difference of 94% and 99%, respectively. Safety outcome analysis suggested that iGlarLixi had lower rates of both confirmed and documented symptomatic hypoglycaemia compared with premix insulin (probabilities of 85% and 93%, respectively) and lower weight gain (probability 98%). Conclusions: iGlarLixi showed similar or improved efficacy and safety versus other intensification choices from BI included in this study, providing a clinically relevant treatment option in people with type 2 diabetes not well controlled on BI.
