Abstract: Aims: To investigate whether the proven benefits of insulin degludec (IDeg) combined with insulin aspart (IAsp), known as IDegAsp, given twice daily, extend across a wide spectrum of patients with diabetes.<br />Materials and Methods: This was a post hoc pooled analysis of 5 phase III randomized, 26-week, open-label, treat-to-target trials comparing IDegAsp twice daily (n = 1111) with one of two comparators: premixed insulin (biphasic insulin aspart 30 [BIAsp 30]) twice daily (n = 561) or IDeg once daily + IAsp (n = 136). Patient data were stratified according to baseline glycated haemoglobin (HbA1c) or fasting plasma glucose (FPG) categories, as well as by baseline duration of diabetes or body mass index (BMI) categories.<br />Results: We conducted a meta-analysis of 5 clinical trials: NCT01513590, NCT01009580, NCT01059812, NCT01680341 and NCT01713530. End-of-trial results were broadly consistent, with differences between IDegAsp and comparators observed in phase III trials. HbA1c results were similar for IDegAsp and the comparators in all baseline characteristic (HbA1c, duration of diabetes or BMI) and category groups (number ranges). Significantly lower FPG level was observed with IDegAsp vs comparators in all baseline characteristic and most category groups (excluding FPG <5.5 mmol/L). Significantly lower insulin doses were observed with IDegAsp vs comparators in all baseline characteristic and half of the category groups, and significantly lower rates of confirmed and nocturnal confirmed hypoglycaemia were observed with IDegAsp vs comparators in all baseline variable and category groups.<br />Conclusions: IDegAsp retains a consistent safety and efficacy profile in patients with different baseline characteristics.<br /> (© 2018 The Authors.
