1119-P: Alleviating Carbohydrate Counting Burden in Type 1 Diabetes (T1D) with the Artificial Pancreas and Empagliflozin (EMPA)

We aimed to assess whether adding Empa to the artificial pancreas can alleviate the burden of carbohydrate counting without degrading glucose control. We conducted a randomized, open-label, crossover, non-inferiority trial in 30 adults with T1D (age 40±15 years, A1c 7.6±0.7%). Each participant used the artificial pancreas on 5 non-consecutive days at home (9-14 hours/day) with: Empa 25mg and (i) carbohydrate counting, (ii) simple meal announcements (pressing a button, no carbohydrate counting), and (iii) no meal announcements (fully automated), and with: no Empa and (iv) carbohydrate counting (control arm) and (v) simple meal announcements. The fully automated artificial pancreas with Empa was inferior to the artificial pancreas with carbohydrate counting without Empa (mean glucose 10.0±1.6 vs. 8.5±1.5 mmol/L, p Disclosure A.
