Closed-loop Insulin Delivery in the General Ward

The study assesses the efficacy and safety of closed-loop glucose control in patients with insulin-treated type 2 diabetes. Phase 1 The study objective is to compare conventional insulin therapy with closed-loop glucose control combined with once daily basal insulin injection over 72 hours in hospitalised insulin treated T2D subjects. Phase 2 The study objective is to compare conventional insulin therapy with closed-loop glucose control up to maximum 15 days in hospitalised insulin treated T2D subjects. Phase 3 The study objective is to compare conventional insulin therapy with closed-loop glucose control applying faster insulin aspart up to maximum 15 days in insulin-treated inpatients receiving parenteral and/or enteral nutrition. Phase 4 The study objective is to compare automated closed-loop control using faster acting insulin aspart with closed-loop control using standard insulin aspart.
