Objective: A CGM sensor that is disposable and requires no calibration may make glucose management easier for people living with diabetes. The present study reports on the interim analysis of a new disposable zero-calibration sensor in adults and youth with type 1 (T1D) or type 2 diabetes (T2D) . Methods: A prospective study enrolled individuals (N=123 adults, aged 18-80 years and N=120 youth, aged 2-17 years) with diabetes at 13 sites in the United States. Raw sensor data were compared with a YSI (Yellow Springs Instruments) or blood glucose (BG) reference and involved N=15388 paired points (pps) from the arm of adults, and N=8627pps from the arm and 7781pps from the buttock of youth. Data were processed using a new zero-calibration algorithm. The primary endpoint was agreement within 20%/20mg/dL (sensor glucose [SG] ≥80mg/dL/ Results: The overall 20%/20mg/dL agreement rate was 90.6% for adults, and 87.8% and 88.5% for youth arm and buttock, respectively. For adults, the 15%/15mg/dL agreement rates were 90.1% and 87.6% (SG 180 mg/dL, respectively) . For youth, the 15%/15mg/dL rates were 93.2% and 86.5% for the arm (SG 180 mg/dL, respectively) and 90.3% and 89.5% for the buttock (SG 180 mg/dL, respectively) . The MARDs were 10.2% for adults, and 10.7% and 10.1% for youth arm and buttock, respectively. Conclusion: These interim findings on the clinical performance of the new disposable and calibration-free sensor are good and may support non-adjunctive insulin dosing in standalone CGM and automated insulin delivery systems.
