iGlarLixi effectively reduces residual hyperglycaemia in Chinese people with type 2 diabetes on basal insulin: A post hoc analysis of the LixiLan-L-CN study

Aim

To compare the effects of iGlarLixi versus insulin glargine 100 U/mL (iGlar) on residual hyperglycaemia in Chinese people with uncontrolled type 2 diabetes (T2D) on prior basal insulin (BI) therapy ± oral antidiabetic drugs in the LixiLan-L-CN study (NCT03798080).

Materials and Methods

In this post hoc analysis, residual hyperglycaemia (i.e. HbA1c ≥ 7.0% [≥ 53 mmol/mol] and fasting plasma glucose [FPG] < 7.0 mmol/L) were assessed over 30 weeks. Outcomes were assessed at week 30 in participants with baseline residual hyperglycaemia, including changes from baseline in HbA1c, FPG, 2-hour postprandial glucose (PPG) and daily BI dose, the proportion of participants with HbA1c less than 7.0% (< 53 mmol/mol) and FPG less than 7.0 mmol/L and the incidence of hypoglycaemia.

Results

Of 421 participants, 124 (29.5%) had baseline residual hyperglycaemia (iGlarLixi, n = 64 [31.7%]; iGlar, n = 60 [29.1%]). At week 30, the residual hyperglycaemia rate decreased to 7.0% with iGlarLixi and increased to 43.3% with iGlar. Among participants with baseline residual hyperglycaemia, a greater proportion achieved both HbA1c and FPG targets at week 30 with iGlarLixi versus iGlar (43.8% vs. 16.7%), and iGlarLixi provided greater reductions in HbA1c (least squares mean [LSM] difference, −0.9% [−9.4 mmol/mol]) and 2-hour PPG (LSM difference, −4.7 mmol/L; both P < .001). Daily BI dose and incidence of hypoglycaemia were similar in the two groups.

Conclusions

The findings of this post hoc analysis suggest that iGlarLixi had greater benefits than iGlar in reducing the rate of residual hyperglycaemia over 30 weeks in Chinese people with suboptimally controlled T2D on prior BI-based therapy.
