Initiation with once-daily BIAsp 30 results in superior outcome compared to insulin glargine in Asians with type 2 diabetes inadequately controlled by oral anti-diabetic drugs

We compare the efficacy and safety of once-daily biphasic insulin aspart 70/30 (BIAsp 30) and insulin glargine in Asian subjects with type 2 diabetes inadequately controlled with oral anti-diabetic drugs (OADs).In a 26-week, open-labelled, randomised, parallel-group, multinational, multicentre, treat-to-target trial, 155 insulin-naïve Asian subjects were treated with either BIAsp 30 or insulin glargine, both in combination with metformin and glimepiride.Change in HbA1c at end of treatment with BIAsp 30 was superior to insulin glargine (BIAsp 30–glargine = −0.36%, 95% CI [−0.64; −0.07], p = 0.015). Mean self-measured plasma glucose (SMPG) at bedtime was significantly lower with BIAsp 30 than insulin glargine (7.98 ± 0.34 mmol/L vs. 9.16 ± 0.33 mmol/L, p = 0.0078). Incidences of minor and daytime hypoglycaemia were higher with BIAsp 30 than those with glargine, but the difference did not reach the statistical significance. No difference was seen in nocturnal hypoglycaemia. The incidence of adverse events was comparable between treatments, with low incidence of serious adverse events and major hypoglycaemia. Mean body weight increased slightly in both groups.In insulin-naïve Asian subjects with type 2 diabetes who are inadequately controlled with OADs, once-daily BIAsp 30 is superior to insulin glargine.
