Summary

The purpose of the study is to compare two closed-loop strategies in terms of glycemic control in Type 1 Diabetes during a camp setting.

The proposed study is a four-segment feasibility study. One segment is a proof of concept study (with two parts) conducted as in-patient clinic study ,the second segment is two-arms, cross-over, randomized and single-center and the third segment is four-arms, parallel, randomized and single-center, in diabetes camp study in subjects with type 1 diabetes on insulin pump therapy and the forth segment is a single arm feasibility in a diabetes camp setting followed by a 3 weeks period at home.

Segment 1 will be divided into two parts: part 1 is a single arm pilot study aim to asses logistical and safety issues in 12 patients and part 2 is a randomized cross over study aim to evaluate glucose performance using closed-loop control. Part 2-is a randomized cross-over (two arms) in-patient study: A total of 12 patients will participate in this part of the study. Following the run-in period subjects will be randomized to participate in two periods of closed-loop treatment, each period will last 36 hours in hospital setting. During the first period, glycemic control will be controlled by the Hybrid closed-loop system and during the second period by Hybrid Logic closed-loop system. The sequence of treatment first period HCL therapy than AHCL or vice versa will be randomly assigned.

Segment 2 is a randomized cross-over (two arms) Camp Study including up to 30 patients. Following the run-in period subjects will be randomized to participate in two periods of closed-loop treatment, each period will last 2days in a camp setting, the total duration of the camp will be up to 6 days. In one period, glycemic control will be controlled by the Hybrid closed-loop system and another period by Hybrid Logic closed-loop system. The sequence of treatment first period HCL therapy than AHCL or vice versa will be randomly assigned.

Segment 3 is a randomized, parallel (four arm) Camp Study including up to 80 patients. Following the run-in period subjects will be randomized to participate in one of 4 intervention arms of closed-loop treatment in camp settings. The duration of the camp will be 12 days in which glycemic control will be controlled by one of 4 versions of closed-loop system: Hybrid Closed Loop (HCL) or one of 3 versions of Advanced Hybrid Closed Loop (AHCL).

Segment 4 is a single arm, feasibility study in a diabetes camp setting followed by a three week period at home. After the completion of segments 1-3, the AHCL system will be optimized and a new version of the system will be created for use in segment 4. Up to 20 subjects will participate in this part of the study. Following a minimum of 5 days run-in period, subjects will be placed in a camp setting and closed loop will be initiated. Subjects will remain in closed loop for 5 days and will have 3 days of challenges, including missed meal bolus, late meal bolus and moderate-intensity exercise. At the conclusion of the camp, subjects will continue to use the system at home in Auto Mode for a period of 21 days.
