Overnight MD-Logic

Summary

Study design: Multicenter,randomized, prospective, open label, cross over, six segments, pilot trial to evaluate blood glucose control overnight under closed-loop insulin delivery with MD-Logic Artificial Pancreas (MDLAP) system in patients with type 1 diabetes.

on the first segment 15 eligible subjects will be enrolled from the three participating centers (5 patients at each center). All 15 patients will participate in the overnight closed loop session in the hospital settings.

On the second segment, 54 eligible subjects will be enrolled (18 at each center). Each subject will participate in the two consecutive overnight sessions in diabetes camp settings, one under closed-loop with MDLAP and one under sensor augmented pump therapy.

In the third segment,9-20 eligible patients will be enrolled at the Israeli center only.Each subject will participate in up to four consecutive overnight under closed loop with MDLAP and up to four additional overnight under regular sensor augmented pump therapy at home.

On the fourth segment, 45-60 patients will be enrolled at the Israeli center only. This segment will be conducted at a diabetes camp and will consist of two main parts. In part 1, 15-20 patients will be randomized to participate in one of the two groups: 2-4 nights under closed loop control while the MD-Logic learning algorithm is activated or 2-4 nights under closed loop control without activating the MD-Logic learning algorithm. In part 2 of the forth segment 30-40 patients will participate in two consecutive24-48 hours sessions,one under closed loop control and the second under sensor augmented pump therapy.

On the fifth segment 40-80 eligible patients will be enrolled at the Israeli center only.The first 10 patients will participate in a pilot session and data gathered at this pilot session will not be used at the final analysis.This segment will consist of two parts. At part 1 each subject will participate in 4weeks-1.5 months period of over nights either using closed-loop with MDLAP or using sensor augmented pump (SAP) therapy.At the end of the first 4 weeks-1.5 months of the study, statistical analysis will be performed in order to decide whether to extend the study with an optional period of extra 4 weeks-1.5 months.In case it will be decided to extend the study, additional 4 weeks-1.5 months intervention period following completion of final visit activities will be offered to participants. Subjects that have participated in the control group (sensor augmented pump therapy) will be offered the opportunity to continue to 4 weeks-1.5 months of closed-loop control and the study group will be offered to switch to sensor augmented pump therapy. In segment 5 part 2, up to 40 patients will be enrolled. Each patient will participate in 3 months study period either using overnight closed loop under MDLAP or sensor augmented pump therapy.Participants in segment 5 part 2 will be offered to participate in part 2A. At this part, sleep quality assessment will be made (by using actigraf and sleep questionnaire) At the end of this period an optional 3 months extension period will be offered with the other arm (cross-over)

Segment 6 will be consist of two main parts.In part 1, up to 40 eligible patients will be enrolled at the Israeli center only. Each subject will participate in up to 72 hours of closed-loop with MDLAP at home and up to 72 hours under regular sensor augmented pump therapy . The sequence of the treatment intervention will be randomly assigned. The sequence of the treatment intervention will be randomly assigned. In part 2 of this segment 40 eligible patients will enrolled at the Israeli center only. Each subject will participate in up to 2 weeks of closed loop with MDLAP at home and up to 2 weeks under regular sensor augmented pump therapy. The sequence of the treatment intervention will be randomly assigned

Objectives: The objective of this feasibility study is to evaluate the safety and efficacy of blood glucose control using the MD-Logic Artificial Pancreas System in individuals with type 1 diabetes in the hospital settings,at a diabetes camp and finally at patient's home.
