    Abstract:
    OBJECTIVE: Insulin detemir (NN304) is a soluble basal insulin analog developed to cover basal insulin requirements. This trial aimed to compare the blood glucose-lowering effect of insulin detemir with that of NPH insulin (NPH) and to evaluate the two treatments with regard to intrasubject variation of fasting blood glucose, incidence of hypoglycemia, dose requirements, and safety. RESEARCH DESIGN AND METHODS: This multicenter open randomized crossover trial in 59 type 1 diabetic subjects comprised a 2-week run-in period on a basal-bolus regimen with NPH insulin once daily, followed by two 6-week periods of optimized basal-bolus therapy with either once-daily insulin detemir or NPH insulin. RESULTS: The area under the curve, in the time interval 23:00-8:00, derived from 24-h serum glucose profiles, was not statistically significantly different for the two treatment periods (insulin detemir:NPH ratio 89.2:83.5, P = 0.59). The intrasubject variation in fasting blood glucose during the last 4 days of treatment was lower for insulin detemir compared with NPH (P < 0.001). Mean dose requirements of insulin detemir were 2.35 times higher (95% CI 2.22-2.48) compared with NPH. During the last week of treatment, fewer subjects experienced hypoglycemic episodes on insulin detemir (60%) compared with NPH treatment (77%) (P = 0.049). CONCLUSIONS: Insulin detemir was as effective as NPH in maintaining glycemic control when administered at a higher molar dose. The results indicate that insulin detemir may provide more predictable fasting blood glucose with lower intrasubject variation and reduced risk of hypoglycemia compared with NPH.
