Safety and effectiveness of biphasic insulin aspart 30 in people with type 2 diabetes switching from basal-bolus insulin regimens in the A1chieve study

Aims: Biphasic insulin aspart 30 allows fewer daily injections versus basal-bolus insulin regimens, which may improve adherence and treatment outcome. This sub-analysis of the observational A(1)chieve study assessed clinical safety and effectiveness of biphasic insulin aspart 30 in people with type 2 diabetes previously receiving basal-bolus insulin regimens. Methods: A(1)chieve was an international, open-label, 24-week study in people with type 2 diabetes starting/switching to biphasic insulin aspart 30, insulin detemir or insulin aspart. This sub-analysis assessed patients switching from insulin glargine- or neutral protamine Hagedorn insulin-based basal-bolus insulin regimens to biphasic insulin aspart 30. Results: 1024 patients were included. At 24 weeks, glycated haemoglobin and fasting plasma glucose were significantly reduced from baseline in both cohorts (all p < 0.001). The proportion reporting any hypoglycaemia, major hypoglycaemia or nocturnal hypoglycaemia was significantly reduced after 24 weeks (all p < 0.05). No serious adverse drug reactions were reported. Both cohorts had significantly improved health-related quality of life (HRQoL; p < 0.001). Conclusions: 24 weeks after switching from basal-bolus insulin regimens to biphasic insulin aspart 30, glycaemic control and HRQoL were significantly improved, and hypoglycaemia was significantly reduced. This suggests that people with type 2 diabetes inadequately controlled on basal-bolus insulin regimens can consider biphasic insulin aspart 30. (C) 2013 Primary Care Diabetes Europe.
