Abstract

This study aimed to evaluate the effectiveness and safety of the MiniMed™ 780G advanced hybrid closed-loop (AHCL) system in people with type 1 diabetes (T1D) previously treated with continuous subcutaneous insulin infusion combined with flash glucose monitoring in a real-life setting. A total of 47 subjects (mean age 41 ± 13.6 years, 60% females, diabetes duration 28 ± 11 years) were included and switched to an AHCL system. Baseline and 6-month data were analyzed. Time in range 70-180 mg/dL increased from 65.3% at baseline to 73.8% at 6 months. Time in hyperglycemia >180 mg/dL decreased from 26.6% to 19.3%. Time in hypoglycemia <70 mg/dL decreased from 4.6% to 2.3%. The coefficient of variation also decreased from 36% to 31.6%. No episodes of severe hypoglycemia, diabetes ketoacidosis, or diabetes-related hospital admissions occurred. In conclusion, the MiniMed 780G AHCL system enables the safe achievement of recommended glycemic targets in people with T1D after 6 months of use.
