Purpose

The hypothesis is that an optimal formulation of fast acting and intermediary acting insulin analogues will improve post prandial glycaemic control in patients with type 1 diabetes.

OBJECTIVE:

The objective is to describe pharmacodynamic (PD) and pharmacokinetic (PK) profiles of Insulin Aspart (IAsp), Biphasic Insulin Aspart (BIAsp) 30, 50 and 70 for a period of 12 hours following a standard test meal on four days respectively in subjects with type 1 diabetes.

Condition	Intervention
Type 1 Diabetes	Drug: NovoRapid, NovoMix 30, Bifasisk Insulin Aspart 50, BIAsp70

Study Type:	Interventional
Study Design:	Treatment, Randomized, Open Label, Dose Comparison, Crossover Assignment, Pharmacokinetics/Dynamics Study
Official Title:	A Comparison of Pharmacodynamics and Pharmacokinetics of Insulin Aspart, Biphasic Insulin Aspart 30, 50 and 70. - A Randomised, Quadruple Cross-Over Trial

Primary Outcome Measures:

Primary endpoint:
• Cmaxglu: Peak plasma glucose following test meal (breakfast). A comparison will be made between BIAsp 50 vs BIAsp 70, BIAsp 30 vs BIAsp 70, BIAsp 30 vs BIAsp 50 and IAsp vs BIAsp 30, 50 and 70.

Secondary Outcome Measures:

Secondary endpoints:
AUCglu: The area under the plasma glucose concentration (0-12, 0-6, 6-12, 0-4, 4-8, 8-12 hours after test meal) after a single injection of one of the four insulin aspart preparation: IAsp (NovoRapid®), Biphasic insulin aspart 30, 50 and 70.
AUCins: The area under insulin aspart concentration (0-12, 0-6, 6-12, 0-4, 4-8, 8-12 hours after test meal) after a single injection of one of the four insulin aspart preparation: IAsp (NovoRapid®), Biphasic insulin aspart 30, 50 and 70.

Detailed Description:

This trial is a single centre, open-label, randomised 4 period cross-over trial, comparing the pk and pd profiles of IAsp, BIAsp 30, BIAsp 50 and BIAsp 70 after a standard test meal in subjects with type 1 diabetes. The profiles will be derived over a 12-hour period after subcutaneous injection in the abdominal region with a single dose of IAsp, BIAsp 30, BIAsp 50 or BIAsp 70 at a test meal. The trial consists of a screening period of 4-21 days and 4 treatment visits
