Background: The MiniMed™ 670G system is FDA-approved and CE-marked for patients with T1D aged ≥7 years. Glycemic outcomes of patients aged 2-75 years with T1D using the system at home for 3 months were evaluated and compared.
Methods: Data from 151 children (n=46, 2-6 years and n=105, 7-13 years) enrolled at 9 sites; and 124 adolescents and adults (n=30, 14-21 years and n=94, 22-75 years) enrolled at 10 sites, during 2-week Manual Mode use (run-in phase) followed by 3-month Auto Mode use (study phase) were analyzed. Glycemic outcomes (HbA1c, time spent at sensor glucose [SG] ranges, SG, and SG variability, etc.) were compared across age groups.
Results: Data from run-in and study phases are shown (Table). Across age groups there was a 0.4% to 0.5% decrease in HbA1c and a 5.5% to 8.8% increase in time in range. During the study phases of the pediatric (2-13 years) and older cohort (14-75 years) trials, there were no episodes of severe hypoglycemia or DKA, and no serious device-related adverse events.
Conclusions: These findings indicate that 3-month MiniMed™ 670G Auto Mode use in patients as young as two years of age with T1D, similar to older cohorts using the system, can safely improve glycemic outcomes compared to 2-week open-loop Manual Mode.
