Low Dose Empagliflozin in Adults With Type 1 Diabetes on Closed Loop Insulin System

The patient will be on the closed-loop insulin system and the intervention drug (placebo, empagliflozin 2.5 mg, or empagliflozin 5 mg) for 14 days. Insulin reductions will be made to avoid hypoglycemia with the drug agent. Remote contact around Day 4 (+/- 2 days) will be made to optimize insulin settings. The last 10 days will be used to assess continuous glucose monitoring data during each intervention. A wash-out period of 7 - 21 days will separate each intervention.
