Extended Use of the Omnipod 5 Automated Insulin Delivery System in Adults With Type 1 Diabetes: 12-Month Extension of a Randomized Controlled Trial.
BACKGROUND: The Omnipod 5 Automated Insulin Delivery (AID) System is safe and effective for individuals managing Type 1 diabetes (T1D). Longer-term studies may provide additional evidence of sustained effectiveness and safety of AID system use in T1D. METHODS: This 12-month extension study was conducted following a multicenter randomized controlled trial (RCT) where participants used either AID (Omnipod 5) or standard therapy (current non-automated pump therapy) for 13 weeks. Participants in France (n = 76) could transition to or continue with AID for an additional 12 months. Glycemic, safety, and psychosocial outcomes during or at the end of the extension phase were compared with baseline or end of RCT, as appropriate. RESULTS: Seventy-five participants enrolled in the extension phase. From RCT baseline to the end of the extension phase, time in range 70-180 mg/dL increased by 17.9% (p < 0.0001) or 4.3 h/day to 62.3%. Time above range > 180 mg/dL and mean sensor glucose decreased by 17.7% and 27.8 mg/dL (both p < 0.0001), respectively. HbA1c decreased from 8.33% to 7.18% (-1.14%; p < 0.0001). Glycemic improvements were maintained for those continuing with AID from the RCT intervention group and for those transitioning to AID from standard therapy. Diabetes Quality of Life-brief and Hypoglycemia Confidence Scale scores were maintained or improved at 6 and 12 months compared to RCT baseline. Adverse events were infrequent (12 per 100 person-years). CONCLUSIONS: Findings support the RCT results, demonstrating safety and sustained improvements in glycemic and psychosocial outcomes with the Omnipod 5 System in adults in France with T1D over 12 months.
