Two Way Crossover Closed Loop MPC vs Control IQ

Participants will undergo one 7-day Intervention Period and one 7-day Control Period in randomized order. During the 7-day intervention, participants will wear an Omnipod to deliver Fiasp insulin and a Dexcom G6 CGM. The CGM system will provide sensed glucose data every 5 minutes. Sensor glucose data will be wirelessly transmitted via Bluetooth Low Energy (BTLE) from the Dexcom G6 to the smartphone master controller every 5 minutes. The smartphone will communicate via BTLE to an Omnipod for insulin delivery. The closed loop system will receive activity data through a Polar M600 watch worn by the participant. Participants will eat one meal in clinic and complete system training on Day 1 and then spend the rest of the 7 days at home. During the 7-day control, the participant will continue their usual diabetes care regimen using the tslim X2 pump with Dexcom G6 with Control IQ enabled.
