Crossover Feasibility Study of Portable AP Device With Zone-MPC and HMS and Adapted I:C and Basal Insulin

The study consists of an evaluation of the Artificial Pancreas device system during two 24-27.5-hour closed-loop phases in an outpatient/hotel environment. Prior to the closed-loop phases, each subject will undergo a 7-day data collection period consisting of his or her usual free-living conditions along with 3 meals of known carbohydrate content. Data from the insulin pump, a continuous glucose monitoring sensor (CGM), diet and exercise records will be collected during this period. These data from this 7-day period will be analyzed in order to come up with adapted basal insulin infusion rates and bolus insulin to carbohydrate (I:C) ratios.
