AIMS: The MiniMed™ 670G system has been available in Europe since October 2018. Herein, the system's real-world performance in individuals with diabetes is evaluated.

MATERIALS AND METHODS: Data uploaded October 2018 to July 2020 by individuals living in Europe were aggregated and retrospectively analyzed. The mean Glucose Management Indicator (GMI), percentage of time spent within (TIR), below (TBR) and above (TAR) glycemic ranges, system use and insulin consumed in users with ≥10 days of SG data after initial Auto Mode start were determined. Another analysis based on suboptimally- (GMI >8.0%) and well-controlled (GMI <7.0%) glycemia pre-Auto Mode initiation was also performed.

RESULTS: Users (N=14,899) spent a mean of 81.4% of the time in Auto Mode and achieved a mean GMI of 7.0±0.4%, TIR of 72.0±9.7%, TBR <3.9 mmol/L of 2.4±2.1% and TAR >10 mmol/L of 25.7±10%, after initiating Auto Mode. When compared to pre-Auto Mode initiation, GMI reduced by 0.3±0.4% and TIR increased by 9.6±9.9% (p<0.0001 for both). Significantly improved glycemic control was observed irrespectively of pre-Auto Mode GMI level <7.0% or >8.0%. While total daily dose of insulin increased for both groups, a greater increase was observed in the latter: an increase due primarily to increased basal insulin delivery. In contrast, basal insulin decreased slightly in well-controlled users.

CONCLUSIONS: Most MiniMed™ 670G system users in Europe achieved TIR >70% and GMI <7% while minimizing hypoglycemia, in a real-world environment. These international consensus-met outcomes were enabled by automated insulin delivery meeting real-time insulin requirements adapted to each individual user.
