Abstract

Introduction

A difference of ≥ 50–55 mg/dL between bedtime and morning glucose (BeAM) values in patients with type 2 diabetes (T2D) on basal insulin is an indicator of poor postprandial glucose control. This analysis compared the effect of treatment with a fixed-ratio combination of insulin glargine/lixisenatide (iGlarLixi) vs insulin glargine (iGlar) on BeAM values, and evaluated the impact of BeAM values on glycemic and safety endpoints.

Methods

In this post hoc analysis of 517 participants from the LixiLan-L trial, change in BeAM values and composite efficacy and safety endpoints stratified by BeAM value < 55 mg/dL or ≥ 55 mg/dL were evaluated in patients with T2D uncontrolled on basal insulin randomized to iGlarLixi or iGlar over 30 weeks (LixiLan-L).

Results

Greater reductions in BeAM values were seen with iGlarLixi vs iGlar, and a higher proportion of patients reached a BeAM value < 55 mg/dL in the iGlarLixi arm. A BeAM value < 55 mg/dL was associated with improved glycemic control, lower risk of hypoglycemia, and a greater proportion of patients achieving glycemic targets without hypoglycemia or weight gain. Greater reductions in BeAM values were seen with iGlarLixi vs iGlar, irrespective of stratification by glycated hemoglobin A1c or glycemic endpoints.

Conclusions

Greater reductions in bedtime-to-morning glucose differential, or BeAM, were observed with iGlarLixi vs iGlar in patients with T2D uncontrolled on basal insulin, reflecting better overall control of both fasting and prandial glucose and more appropriate matching of therapy to physiologic needs.
