Reducing Diabetes Burden in Medtronic's Automated Insulin Delivery Systems.

The MiniMed™ 780G advanced hybrid closed-loop system (MM780G) builds on the basal automation and low-glucose protection features of the MiniMed™ 670G and 770G systems. While previous publications have focused on glycemic control improvements with MM780G, burden reduction has not been fully described. Data from two 3-month pivotal trials for the MM670G with Guardian™ Sensor 3 (GS3) (104 adults; 125 children) and MM780G with Guardian™ 4 Sensor (G4S) (67 adults;109 children) were compared. Real-world data (RWD) from United States users ( = 3851) transitioning from MM770G+GS3 to MM780G+G4S were also analyzed. Analyses included a new metric for diabetes management burden (i.e., pentagon composite metric), glycemic outcomes and system burden (e.g., closed-loop exits and fingersticks per day). Diabetes burden metric (-22.8% and -28.5%), time in range (+3.1% [* = 0.035] and +6.4% [ < 0.001]) and time below range (-1.8% [* < 0.001] and -0.7% [* < 0.001]) significantly improved, compared to MM670G for adult and pediatric participants, respectively. The pediatric mean sensor glucose (SG) reduced by -8.6 mg/dL (* < 0.001), while the adults' saw no change. Closed-loop use significantly increased for both cohorts (+17.1% [* < 0.001] and +20.5% [* < 0.001]). Closed-loop exits were significantly reduced to about 1 per week (-0.5 [* < 0.001] and -0.7 [* < 0.001]); fingerstick tests were also reduced (-6.2 [* < 0.001] and -6.9 [* < 0.001]). Similar outcomes were observed from U.S. RWD. MiniMed™ 780G with G4S use was associated with significant reduction in diabetes management burden with fewer closed-loop exits, fingersticks and other interactions, and improvements in glycemic control when compared to the MiniMed™ 670G with GS3.
