Automated Insulin Delivery in Pregnant Patients With Type 1 Diabetes With Extension Into Outpatient at Home

The system will be evaluated on up to 21 pregnant adult subjects with type 1 diabetes age 18-45 years old at three clinical sites (Sansum Diabetes Research Institute, Mayo Clinic Rochester MN and Mt Sinai Hospital, New York City). Subjects will complete a 48-60 hour closed-loop (CL) session in a supervised outpatient environment with medical staff present. During the session, subjects will bolus for all meals and snacks, and will perform their usual daily activities while being accompanied by study medical staff. For subjects who wish to continue use of the system, they will be offered the option of continuing use of the system at home in an extension phase, for the rest of their pregnancy.
