Study Description

Brief Summary:

The purpose of this study is to see if an automated insulin management system ("study system") can safely be used at home to manage blood sugar. The study system includes (1) a CGM that measures glucose levels, (2) a computer program on a smartphone that determines how much insulin is needed and allows the study participant user to control the whole system, and (3) an insulin pump that delivers the insulin. The CGM will be from Dexcom. The pump will be from Roche. The CGM and pump are similar to the devices that are currently available for people to purchase and use. However, the smartphone device, the CGM sensor type used with it, and the overall study system can only be used for research at this time.

The study will be completed by about 24 individuals at 6 centers in the United States and Europe. This study has several phases and will take about 11-14 weeks to complete depending on whether the study participant is a CGM user or not.

At selected sites (based on subject eligibility and availability), approximately 10-20 subjects who exhibit safe and competent use of the system at home will be given the option to continue home use of the system in Day-and-Night Closed-Loop mode for up to 5 months.

24. LBGI - Main Phase, Day and Night [ Time Frame: 2 weeks ]
    Low Blood Glucose Index (LBGI) - Main Phase, Day and Night. The LGBI metric is used to quantify the risk of hypoglycemia. A higher LBGI implies more mild hypoglycemic events or less severe hypoglycemic events.
25. LBGI - Main Phase, Night Only [ Time Frame: 2 weeks ]
    Low Blood Glucose Index (LBGI) - Main Phase, night only (23:00 - 07:00). The LGBI metric is used to quantify the risk of hypoglycemia. A higher LBGI implies more mild hypoglycemic events or less severe hypoglycemic events.
26. LBGI - Main Phase, Day Only [ Time Frame: 2 weeks ]
    Low Blood Glucose Index (LBGI) - Main Phase, day only (07:00 - 23:00). The LGBI metric is used to quantify the risk of hypoglycemia. A higher LBGI implies more mild hypoglycemic events or less severe hypoglycemic events.
27. AOC 70 mg/dL - Main Phase, Day and Night [ Time Frame: 2 weeks ]
    Area Over the Curve (AOC) 70 mg/dL - Main Phase, Day and Night. The hypoglycemia AOC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, a hypoglycemia AOC of 1 mg/dl can denote a glucose of 60 mg/dl for 10% of the time (10 mg/dl below threshold * 10% = 1 mg/dl) or 65 mg/dl for 20% of the time (5 mg/dl below threshold * 20% = 1 mg/dl). Note that it is based on relative (%) rather than absolute time so there is no time element in the resulting units.
28. AOC 70 mg/dL - Main Phase, Night Only [ Time Frame: 2 weeks ]
    Area Over the Curve (AOC) 70 mg/dL - Main Phase, night only (23:00 - 07:00). The hypoglycemia AOC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, a hypoglycemia AOC of 1 mg/dl can denote a glucose of 60 mg/dl for 10% of the time (10 mg/dl below threshold * 10% = 1 mg/dl) or 65 mg/dl for 20% of the time (5 mg/dl below threshold * 20% = 1 mg/dl). Note that it is based on relative (%) rather than absolute time so there is no time element in the resulting units.
29. AOC 70 mg/dL - Main Phase, Day Only [ Time Frame: 2 weeks ]
    Area Over the Curve (AOC) 70 mg/dL - Main Phase, day only (07:00 - 23:00). The hypoglycemia AOC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, a hypoglycemia AOC of 1 mg/dl can denote a glucose of 60 mg/dl for 10% of the time (10 mg/dl below threshold * 10% = 1 mg/dl) or 65 mg/dl for 20% of the time (5 mg/dl below threshold * 20% = 1 mg/dl). Note that it is based on relative (%) rather than absolute time so there is no time element in the resulting units.
30. HBGI - Main Phase, Day and Night [ Time Frame: 2 weeks ]
    High Blood Glucose Index (HBGI) - Main Phase, Day and Night. The HBGI metric is used to quantify the risk of hyperglycemia. A higher HBGI implies more mild hyperglycemic events or less severe hyperglycemic events.
31. HBGI - Main Phase, Night Only [ Time Frame: 2 weeks ]
    High Blood Glucose Index (HBGI) - Main Phase, night only (23:00 - 07:00). The HBGI metric is used to quantify the risk of hyperglycemia. A higher HBGI implies more mild hyperglycemic events or less severe hyperglycemic events.
32. HBGI - Main Phase, Day Only [ Time Frame: 2 weeks ]
    High Blood Glucose Index (HBGI) - Main Phase, day only (07:00 - 23:00). The HBGI metric is used to quantify the risk of hyperglycemia. A higher HBGI implies more mild hyperglycemic events or less severe hyperglycemic events.
33. ADRR - Main Phase, Day and Night [ Time Frame: 2 weeks ]
    Average Daily Risk Range (ADRR) - Main Phase, Day and Night. ADRR is a metric that categorizes risk for hyper and hypoglycemic events. Low risk is scored 0-19, moderate risk is scored 20-40, and high risk is 40 and above.
34. AUC 180 mg/dL - Main Phase, Day and Night [ Time Frame: 2 weeks ]
    Area Under the Curve (AUC) 180 mg/dL - Main Phase, Day and Night. The hyperglycemic AUC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, the hyperglycemic AUC is 28 (mg/dl)*days for Patient A and 56 (mg/dl)*days for Patient B when using 180 as the threshold. But this is artificial because Patient B wore the sensor twice as long. So we similarly scale it relative to the number of readings to reflect a mean rather than a sum. So we say hyperglycemic AUC = 4 mg/dl for both patients. Note that time disappears from the units in the scaled version. It represents the mean value of max(glucose-180, 0).
35. AUC 180 mg/dL - Main Phase, Night Only [ Time Frame: 2 weeks ]
    Area Under the Curve (AUC) 180 mg/dL - Main Phase, night only (23:00 - 07:00). The hyperglycemic AUC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, the hyperglycemic AUC is 28 (mg/dl)*days for Patient A and 56 (mg/dl)*days for Patient B when using 180 as the threshold. But this is artificial because Patient B wore the sensor twice as long. So we similarly scale it relative to the number of readings to reflect a mean rather than a sum. So we say hyperglycemic AUC = 4 mg/dl for both patients. Note that time disappears from the units in the scaled version. It represents the mean value of max(glucose-180, 0).
36. AUC 180 mg/dL - Main Phase, Day Only [ Time Frame: 2 weeks ]
    Area Under the Curve (AUC) 180 mg/dL - Main Phase, day only (07:00 - 23:00). The hyperglycemic AUC is scaled to the number of CGM readings so the time factor cancels out. Technically, the units would be mg/dl, but this might seem unintuitive since it is incremental relative to a threshold. For example, the hyperglycemic AUC is 28 (mg/dl)*days for Patient A and 56 (mg/dl)*days for Patient B when using 180 as the threshold. But this is artificial because Patient B wore the sensor twice as long. So we similarly scale it relative to the number of readings to reflect a mean rather than a sum. So we say hyperglycemic AUC = 4 mg/dl for both patients. Note that time disappears from the units in the scaled version. It represents the mean value of max(glucose-180, 0).

10. Episodes of Severe Hypoglycemia Events - Extension Phase [ Time Frame: 5 months ]
    Episodes of severe hypoglycemia events during the 5-month extension phase defined as an event requiring assistance of another person due to altered consciousness to actively administer carbohydrate, glucagon, or other resuscitative actions. This means that the subject was impaired cognitively to the point that he/she was unable to treat him or herself, was unable to verbalize his or her needs, was incoherent, disoriented, and/or combative, or experienced seizure or coma. These episodes may be associated with sufficient neuroglycopenia to induce seizure or coma. If plasma glucose measurements are not available during such an event, neurological recovery attributable to the restoration of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.
