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.
This clinical trial is a safety and feasibility study to assess the performance of an artificial pancreas (AP) system using the Zone Model Predictive control (Zone-MPC) and Health Monitoring System (HMS) algorithms embedded into the iAPS platform for pregnant patients with type 1 diabetes (T1D).
