Study to Compare Efficacy of the MiniMed Paradigm REAL-Time System Vs. MDI in Subjects Naive to Insulin Pump Therapy (STAR3)

• Difference in Frequency of Severe Hypoglycemia From Baseline to Week 52; [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: Yes ]
  Severe Hypoglycemia is defined as a hypoglycemic episode absolutely requiring assistance from another person and preferably accompanied by a confirmatory Blood Glucose (BG) by finger stick of less than 50 mg/dL (2.8 mmol/L). The frequency evaluates the total number of events. This will be analyzed and compared between the two study arms from baseline to week 52.
• Overall Difference in Rate of Severe Hypoglycemia Events Between Study Arms From Baseline to Week 52 [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: Yes ]
  Severe Hypoglycemia is defined as a hypoglycemic episode absolutely requiring assistance from another person and preferably accompanied by a confirmatory BG by finger stick of less than 50 mg/dL (2.8 mmol/L). The rate evaluates the number of participants that experienced at least one severe hypoglycemia event and compares this number between the two study arms from Baseline to week 52. This measure identifies the rate or frequency of unique participant events.
• Changes in Hypoglycemia Area Under the Curve (AUC) From Baseline to Week 52; [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: No ]
  Hypoglycemia is defined as a recorded blood glucose event <70mg/dL. The amount of time spent below this parameter will be analyzed and compared between groups from Baseline to Week 52.
• Changes From Baseline in Hyperglycemia Area Under the Curve (AUC) From Baseline to Week 52 [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: No ]
  Hyperglycemia is defined as a recorded blood glucose event > 180 mg/dL. The amount of time spent above this parameter will be analyzed and compared between groups from Baseline to Week 52.
• Quality of Life - Hypoglycemia Fear Scale (HFS), Overall Score [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: No ]
  Difference of Baseline and 52 Weeks in Hypoglycemia Fear Scale (HFS) Overall Score between the two study arms (adult subjects only) is presented. Both baseline and 52 weeks scores range from 0-100, with lower scores suggest higher satisfaction. Therefore, a negative number in the difference suggests higher satisfaction at 52 Weeks than Baseline.
• Health Economic Outcomes (MRU) [ Time Frame: Baseline and 52 weeks ] [ Designated as safety issue: No ]
• Quality of Life - Short Form-36 (SF-36v2™), General Health [ Time Frame: Baseline and 52 Weeks ] [ Designated as safety issue: No ]
  Difference of Baseline and 52 Weeks in Short Form-36 (SF-36v2™), General Health, between the two study arms (adult subjects only) is presented. Both baseline and 52 weeks scores range from 0-100, with higher scores suggest higher satisfaction. Therefore, a positive number in the difference suggests higher satisfaction at 52 Weeks than Baseline.
• Quality of Life - Insulin Delivery System Rating Questionnaire (IDSRQ) for Subject Satisfaction With Type of Insulin Therapy [ Time Frame: Baseline and 52 Weeks ] [ Designated as safety issue: No ]
  Difference of Baseline and 52 Weeks in Insulin Delivery System Rating Questionnaire (IDSRQ) for Subject Satisfaction with Type of Insulin Therapy, between the two study arms is presented. Both baseline and 52 weeks scores range from 0-100, with higher scores suggest higher satisfaction. Therefore, a positive number in the difference suggests higher satisfaction at 52 Weeks than Baseline.

• Incidence and frequency of severe hypoglycemia;
• Measure of glycemic variability (AUC);
• Quality of Life;
• Health Economic Outcomes (MRU)

Primary Outcomes: Average decrease in A1c from baseline to end of Study Phase (52 weeks) for subjects in the "722 Group" is greater than that for subjects in the "Control (MDI) Group".

Secondary Outcomes: Incidence and frequency of severe hypoglycemia; Measure of glycemic variability, Area Under the Curve (AUC); Quality of Life; and Health Economic Outcomes (MRU)

Glycemic control remains a significant challenge for adult, adolescent and pediatric Type 1 diabetics. The current first line standard of care continues to be MDI therapy utilizing a long acting analog insulin. Continuous Glucose Monitoring (CGMS) is currently used by clinicians to record continuous, retrospective glucose measurements, which aid in identification of glycemic excursion patterns. This data is then used to make future therapy change recommendations. The MiniMed Paradigm REAL-Time System transmits real-time glucose measurements to the insulin pump every 5 minutes, allowing users to view their current glucose values, as well as to review glycemic excursions and trends over a 24-hour period. Additionally, data can be downloaded from the monitor to a personal computer, using appropriate software, so that the patient and physician can see a complete picture of glucose trends over time. The System will also alert users of high and low glucose levels, and allow subjects and their clinicians to treat to a therapeutic target HbA1c under carefully monitored conditions.

Subjects wearing the MiniMed Paradigm REAL-Time System will be compared to subjects that continue on their current MDI therapy, that includes a long acting analog insulin, over a 12 month period to evaluate changes in glycemic control (HbA1c).
