Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate the performance of a software-algorithm based insulin therapy to control blood glucose in Type 1 diabetic patients;Secondary Objective: To investigate safety of the software algorithm To investigate the feasibility to continuously monitor blood glucose To simulate to drive the software algorithm by continuous blood glucose data;Primary end point(s): 15 min in the predefined glucose ranges: post-prandial phase (3 hours after meal): 70-180 mg/dl (3.9-10 mmol/l), all other phases: 70-140 mg/dl (3.9-7.8 mmol/l);Timepoint(s) of evaluation of this end point: Every 15 min over a period of 24 hours | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Distribution of measured glucose values over the glycaemic range during the entire 24 hour intervention period • Distribution of measured glucose values over the glycaemic range 3 hours after a meal • Number of hypoglycaemic events • Number and reasons for oral glucose intake • Injected insulin dose • Malfunction of the algorithm • Accuracy of the glucose monitoring unit • Difference between the glucose derived from i.v. microdialysis and the corresponding reference glucose;Timepoint(s) of evaluation of this end point: Every 15 min over a period of 24 hours | — |
