The Monitoring Study

Participants will wear a Bionic Pancreas that uses glucagon and insulin (bihormonal) to automate their glucose control based on continuous glucose monitor readings.

Participants will wear a Bionic Pancreas that uses just insulin (insulin-only) to automate their glucose control based on continuous glucose monitor readings.

During half of the study arms (one each bihormonal bionic pancreas, insulin-only bionic pancreas and usual care) the subjects will be remotely monitored for device connectivity and hypoglycemia, and will be notified by study staff any time their continuous glucose monitor reads less than 50 mg/dl for 15 mintues.
