Closed-loop Control of Glucose Levels (Artificial Pancreas) for 5 Days in Adults With Type 1 Diabetes

NCT02488616 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2018-01-31

No results posted yet for this study

Summary

Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings.

The main objective of this project is to compare the efficacy of single-hormone closed-loop strategy and sensor-augmented pump therapy to regulate glucose levels in outpatient settings for 5 consecutive days in adults with type 1 diabetes.

The investigators hypothesized that single-hormone closed-loop strategy will increase the time spent in the target range compared to sensor-augmented pump therapy.

Conditions

Interventions

OTHER

5-day intervention with single-hormone closed-loop strategy

A sensor will be inserted on the day prior to the first day of the intervention by the participants. On the first day of the intervention, participants will be admitted to the clinical research facility anytime between 8:00 am and 11:30 am. Training on connection and disconnection of the system, meal boluses, etc. will be given. Competency on the use of study devices will be assessed by a team member. Only participants demonstrating competency on use of study devices will be allowed to continue to the home study phase. Participants will be advised to continue with study intervention at home for the next 5 days.

OTHER

5-day intervention with sensor-augmented pump therapy

A sensor will be inserted on the day prior to the first day of the intervention by the participants. The participant will also have to install the study insulin pump. Participants will be advised to continue with study intervention at home for the next 5 days. Participants will have been previously shown how to use the study insulin pump.

DEVICE
