Brief Summary:
A previous study showed that absorption and glucose-lowering action of rapid-acting insulin analogues occurred twice as fast when these analogues were administered by jet injection technology rather than by conventional insulin pen in healthy non-diabetic subjects. This study investigates if the rapid-acting insulin analogue aspart (Novorapid®) injected with jet-injection or a conventional insulin pen prior to a standardised meal in patients with diabetes shows the same difference in the pharmacokinetic and pharmacodynamic profile.
Detailed Description:
A previous study showed that absorption and glucose-lowering action of rapid-acting insulin analogues occurred twice as fast when these analogues were administered by jet injection technology rather than by conventional insulin pen in healthy non-diabetic subjects. This study investigates if the rapid-acting insulin analogue aspart (Novorapid®) injected with jet-injection or a conventional insulin pen prior to a standardised meal in patients with diabetes (type 1 and type 2) shows the same difference in the pharmacokinetic and pharmacodynamic profile.The pharmacokinetic and pharmacodynamic profile of insulin aspart will be derived from the time-action profiles of insulin and glucose, respectively, in response to insulin injected directly prior to a standardised meal. All patients will be investigated twice, where on one occasion the jet-injector device will be used to inject an individualised dose of insulin and a conventional insulin pen to inject a placebo solution, and on the other occasion insulin will be injected with the conventional pen and placebo with the jet-injector. The order of these occasions will be randomised and blinded to both the investigator and the participating patient. The primary endpoint is the hyperglycaemic burden as reflected by area under the baseline-subtracted plasma glucose concentration time-curve from time 0 to 2 h after insulin injection and meal ingestion (BG-AUC0-2h). Secondary study endpoints are the area under the baseline-subtracted plasma glucose concentration time-curve from time 0 to 6 h (BG-AUC0-6h), maximal glucose excursion (BGmax), time to maximal glucose excursion (T-BGmax), time until plasma glucose has returned to baseline (T-BGBL), maximal insulin concentration (C-INSmax), time to maximal insulin concentration (T-INSmax), area under the insulin concentration curve (INSAUC) and time until 50% of insulin absorption (T-INSAUC50%) after insulin injection and meal ingestion.
