Feasibility Study for Training Pump Naïve Subjects To Use The Paradigm® System And Evaluate Effectiveness (STAR2) Phase 4 29 Multi-Center
Clinical Trial NCT00530023 (STAR2) was designed to study Treatment for Type 1 Diabetes. This was a Phase 4 interventional study that is now completed. The study started on 1 February 2006, with plans to enroll 29 participants. Led by Medtronic Diabetes, the expected completion date was 1 September 2006. The latest data from ClinicalTrials.gov was last updated on 10 June 2011.
Brief Summary
Feasibility study to compare the effectiveness of the Paradigm Sensor Augmented System versus subjects continuing to administer insulin in multiple dose injections. Evaluate the educational materials and time required for training subjects naïve to continuous subcutaneous insulin infusion (CSII) to use the Paradigm 722 REAL Time System in preparation for a large multi-center clinical trial
Detailed Description
Many subjects with Type 1 diabetes continue to manage their disease utilizing multiple daily injections, but despite frequent blood glucose checks, are unable to control their glycemic variability or lower their A1C levels. The MiniMed Paradigm REAL-Time System transmits sensor glucose values to the insulin pump every 5 minutes, allowing users to view their current glucose values as well as glycemic excursions and tr...Show More

Primary Outcome Measures
Secondary Outcome Measures
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Change in A1C From Baseline to Week 15 | Change in A1C measured from Baseline to week 15 will be compared. A1C measured as percent of glycated hemoglobin using a standardized assay for all subjects. | Baseline and 15 weeks |
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Incidence of Severe Hypoglycemia Events Baseline to Week 15 | The total number of severe hypoglycemia events, defined as episodes requiring assistance from another person (i.e., subject is unable to treat self and requires carbohydrate or glucagon or other resuscitative actions) compared between the two study arms from Baseline to Week 15. | Baseline and 15 weeks |
Blood Glucose Monitoring System - Ratings Questionnaire (BGMS-RQ) Assessed at Baseline and Week 15 | Questionnaire measuring overall satisfaction with the relevant blood glucose monitoring system. Assessed at Baseline and Week 15 and compared between arms. Likert scale used with responses graded as the lowest number being the least acceptable and the highest number the most acceptable. The scoring was then transformed to a 0 - 100 scale again with the higher number representing the most acceptable response. | Baseline and 15 weeks |
Insulin Delivery System - Ratings Questionnaire (IDS-RQ) Assessed at Baseline and Week 15 | Questionnaire measuring overall satisfaction with the relevant insulin delivery system. Assessed at Baseline and Week 15 and compared between arms. Likert scale used with responses graded as the lowest number being the least acceptable and the highest number the most acceptable. The scoring was then transformed to a 0 - 100 scale again with the higher number representing the most acceptable response. | Baseline and 15 weeks |
Hypoglycemia Fear Scale (HFS) Assessed at Baseline and Week 15 | Questionnaire evaluating change in the subjects' fear of potential hypoglycemia events assessed Week 15 and compared between arms. Likert scale of 0 - 4 used with responses graded as the lowest number being the most acceptable and highest number the least acceptable. The questionnaire has two sections, Behavior and Worry with a maximum possible score of 60 for Behavior (15 X 4) and 72 for Worry (18 X 4). The total combined scoring of these two sections was then assessed at Baseline and Week 15 and the change from Baseline to Week 15 for each arm reported as the end of study result. | Baseline and 15 weeks |
