The Omnipod 5 AID System is a tubeless hybrid closed-loop system with on-body operation and customizable glucose targets. Safe and effective system use was demonstrated in children aged 2-5.9y with type 1 diabetes (T1D) during a 3-mo pivotal study. To evaluate durability of glycemic benefit, we analyzed results from 9mo of an ongoing extension study, totaling 12mo of system use. In the pivotal study, participants used the system for 3mo at home, after 14d of their standard therapy (ST, pump or multiple daily injections) . They were then invited to participate in the extension study. Safety endpoints were occurrence of severe hypoglycemia (SH) and diabetic ketoacidosis (DKA) . Glycemic outcomes were A1C and percent time in ranges (TIR 70-180 mg/dL, TBR <70 mg/dL, TAR >180 mg/dL) during 3-mo AID intervals compared with ST. All pivotal trial participants (N=80) , aged (mean±SD) 4.7±1.0y with T1D duration 2.3±1.1y and total daily insulin of 14±4U (range: 5.3-27U) at baseline, enrolled in the extension. Improved outcomes were observed for up to 12mo, including lower A1C and greater TIR during each AID interval compared with ST (all p<0.05, Table) . There were no episodes of DKA or SH in the 12-mo study. The safety and improved glycemic outcomes from the initial 3mo pivotal study persisted for an additional 9mo, indicating the potential long-term benefit of the Omnipod 5 System in very young children with T1D.
