Feasibility Study of the Effect of Intra-Dermal Insulin Injection on Blood Glucose Levels After Eating
- Conditions
- Diabetes Mellitus, Type 1
- Interventions
- Drug: Regular insulin (Humulin)Drug: Insulin lispro (Humalog)
- Registration Number
- NCT00553488
- Lead Sponsor
- Becton, Dickinson and Company
- Brief Summary
This study is to determine the effect of intra-dermal (ID) administration of regular and of rapid-acting insulin, before eating, on blood glucose levels for several hours after a standard meal (a mixed, liquid meal). Insulin will also be given normally, subcutaneously, for control or comparison purposes. The hypothesis or expectation is that ID insulin will work more quickly and control blood glucose levels better than SC injection.
- Detailed Description
Previous studies have shown that intra-dermal (ID) insulin administration results in a more rapid onset of action in comparison to subcutaneous (SC) administration as measured by glucose infusion rate (GIR) under glucose clamp conditions.The aim of this study is to investigate whether ID administration of regular human insulin or rapid-acting insulin analogue leads to reduced postprandial glycemic excursions in comparison to SC application under highly standardized experimental conditions. Effects on the occurrence of hypoglycemia will also be investigated, as well as pK and pD comparisons between different insulin formulations administered ID. This is a mono-center, open-label, randomized, 5-period crossover study in patients with type 1 diabetes
