Improved glycaemic control in people with type 2 diabetes initiating or switching to IDegAsp in a real-world setting in China.

Aims: To investigate glycaemic control in Chinese adults with type 2 diabetes (T2D) initiating, or switching to insulin degludec/insulin aspart (IDegAsp), a co-formulation of basal, and bolus insulin, in a real-world setting.

Materials and methods: A 20-week, prospective, single-arm, open-label, non-interventional study was conducted in Chinese adults with T2D initiating, or switching to IDegAsp after anti-hyperglycaemic treatment with oral antidiabetic drugs (OADs), other insulins, or glucagon-like peptide-1 receptor agonists. The primary endpoint was a change in HbA_1c from baseline to end of the study; the secondary endpoints included a change in fasting plasma glucose and Diabetes Treatment Satisfaction Questionnaire (DTSQ) score.

Results: Significant reductions were observed in mean HbA_1c and fasting plasma glucose, among both the overall population (N = 878; -1.27%-points [95% CI: -1.36; -1.19]; p < 0.0001, and -1.61 mmol/L [95% CI: -1.81; -1.41]; p < 0.0001, respectively), and in subgroups switching from OADs only, or basal, or premix insulins ± OADs. The mean total DTSQ score increased from 26.4 (baseline) to 31.6 (end-of-study). No significant, or unexpected tolerability, or safety issues were observed. Significant reductions were observed in incidence rates of non-severe (rate ratio 0.37 [95% CI: 0.24; 0.59]; p < 0.0001) and nocturnal non-severe (rate ratio 0.45 [95% CI: 0.21; 0.94]; p = 0.0326) hypoglycaemic episodes.

Conclusions: In a broad, real-world Chinese population of adults with T2D, initiating or switching to IDegAsp was associated with improved glycaemic control and lower rates of hypoglycaemia. The use of IDegAsp could be an effective treatment option for those with suboptimal glycaemic control or therapeutic inertia.
