Clinical Trial 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.


Clinical Trial Description

The study phases are as follows:

- Screening visit to see if you are eligible for the study and to determine how long you will need to use the study CGM (visit 1)

- Up to 3 weeks using the study CGM (depends on your current CGM use), followed by an office visit (visit 2)

- 2 weeks using the study insulin pump and study CGM together

- Full day visit in clinic or hotel for training using the system (visit 3)

- 1 week using the system without automated insulin delivery or suspension

- 2-day hotel or clinic visit for closed-loop training (visit 4),

- 16-19 days using the system in the evening and overnight only followed by an office visit (visit 5)

- 16-19 days using the system for the full 24 hours

- Final study clinic visit (visit 6)

- Option 5 month extension phase of day-and-night closed-loop home use ;
