Biphasic insulin aspart 30 treatment improves glycaemic control in patients with type 2 diabetes in a clinical practice setting: Chinese PRESENT study.
OBJECTIVE
PRESENT (Physicians' Routine Evaluation of Safety and Efficacy of NovoMix 30 Therapy) is the largest, multinational, open-labelled, uncontrolled and completed observational study of the efficacy and safety of biphasic insulin aspart 30 (BIAsp 30) treatment in clinical practice. We present results of 3 months of treatment in Chinese patients with type 2 diabetes mellitus who were inadequately controlled on current treatment.


METHODS
Patients received BIAsp 30 treatment with or without oral antidiabetic drugs (OADs). Patients were categorized according to their treatment prior to entering the study: drug-naive (n = 3697), OAD (n = 4754), insulin (n = 2392) or OAD + insulin (n = 817).


RESULTS
At 3 months, significant reductions from baseline were observed in the mean haemoglobin A(1c) (HbA(1c)) (-2.24 +/- 1.67, -2.04 +/- 1.57, -1.82 +/- 1.49 and -1.86 +/- 1.61%), fasting plasma glucose (-3.93 +/- 3.12, -3.51 +/- 2.55, -2.99 +/- 2.93 and -3.38 +/- 3.16 mmol/l) and postprandial plasma glucose (-7.09 +/- 4.92, -6.51 +/- 4.02, -5.20 +/- 4.31 and -5.50 +/- 4.32 mmol/l) in the drug-naive, OAD, insulin and insulin + OAD groups respectively (p < 0.001). The proportions of patients in each group achieving target HbA(1c) of less than 7% were higher at 3 months (49.5, 51.8, 51.0 and 48.3%) compared with baseline (3.2, 4.2, 7.1 and 8.3%). The rates of hypoglycaemic episodes (events per patient-year) were lower at the end of the study in all the groups compared with baseline. Hypoglycaemic episodes were mostly minor and diurnal in nature. A total of 151 adverse drug reactions were reported, of which five were serious adverse drug reaction (SADRs). These SADRs were all symptoms of local hypersensitivity.


CONCLUSIONS
The use of BIAsp 30 monotherapy or in combination with OADs in clinical practice was efficacious and safe in Chinese patients with poorly controlled type 2 diabetes.
