LixiLan-O, a randomized, 30-week, open-label study compared the fixed-ratio combination of insulin glargine/lixisenatide (iGlarLixi) with insulin glargine (iGlar) or lixisenatide in patients inadequately controlled on metformin alone or combined with a second OAD. This exploratory subgroup analysis examines the efficacy and safety of iGlarLixi vs. iGlar in patients with baseline HbA1c ≥8.0% receiving metformin plus a second OAD at screening; the second OAD was a sulfonylurea in 93.8% of patients. Mean age was 59.2 years, mean BMI was 31.5 kg/m2, mean diabetes duration was 10.0 years, and mean duration of second OAD use was 4.5 years. Compared with iGlar alone, the iGlarLixi-treated group demonstrated greater mean reductions from baseline in HbA1c, 2-h PPG, and weight, greater proportions achieving HbA1c <7.0%, or a composite endpoint of HbA1c <7.0% with no weight gain (Table). There were no differences between the groups in change in FPG, or in insulin dose at Week 30 (40.7 vs. 40.2 U/day, respectively; p=0.8664). Incidences of documented symptomatic hypoglycemia (plasma glucose ≤70 mg/dL) were similar between groups (29.0% and 27.9%, respectively). Patients in this difficult-to-treat subgroup with advanced T2D and higher baseline HbA1c achieved better glycemic control without increased risk of hypoglycemia when intensified with iGlarLixi compared with iGlar.
