Switching from human insulin to biphasic insulin aspart 30 treatment gets more patients with type 2 diabetes to reach target glycosylated hemoglobin <7% : the results from the China cohort of the PRESENT study

Background The clinical importance of glycaemic control in patients with diabetes has been well established. This study aimed to explore twice-daily biphasic insulin aspart 30 (BIAsp 30) for insulin initiation in patients with type 2 diabetes mellitus (T2DM) who had poor glycaemic control with human insulins (HIs). We use data from a Chinese cohort of the PRESENT study. Methods In the 3-month study, Chinese subjects with T2DM started insulin therapy with BIAsp 30 in routine care. Glycaemic control was measured by glycosylated hemoglobin (HbA(1c)), fasting plasma glucose (FPG) and posting plasma glucose (PPG). The safety assessment included hypoglycaemia and other adverse events. Results A total of 1989 subjects previously treated with His were switched to BIAsp 30 for 3-month treatment. Mean HbA(1c), FPG and PPG were significantly improved after the therapy. The overall rate of hypoglycaemia decreased at the end of the trial except for the patients previously treated with long-acting insulin. Most of the events were minor and diurnal hypoglycaemia. Only one serious adverse drug reaction (SADR), a local hypersensitivity, was reported. The majority of the patients (>= 96.7%) and physicians (>= 84.7%) were either satisfied or very satisfied with the treatment using BIAsp 30 compared with previous HI therapy. Conclusion The BIAsp 30 treatment improved both glycaemic control and patients' satisfaction without increasing hypoglycaemia in T2DM subjects inadequately controlled by HIs.
