Pilot Study of Closed-Loop Glucose Control in People With Type 1 Diabetes (BPK004)

Subjects used the OmniPod Insulin Management System (Insulet Corp.) and Insulin lispro (Eli Lilly, Indianapolis, IN). MPC algorithm suggested insulin boluses every 15 min, which, if accepted, were programmed into the insulin pump by the attending physician. Otherwise, the admission remained the same as in the open-loop admission (i.e. meals, sleep, etc...).

This admission was to assess the subjects' level of glucose control and created a base to compare the performance of the closed-loop system. Subjects monitored their own blood glucose values and administer their basal/bolus as they would at home. Subjects used their own insulin pumps and Insulin lispro (Eli Lilly, Indianapolis, IN). Otherwise, the admission remained the same as in the closed-loop admission (i.e. meals, sleep, etc...).
