Arms of the Study
Arm 1
Experimental
AI Advisor-driven at-home closed loop system initiation and parameter adaptation
In this single-arm intervention trial, all participants will use the study system (t:slim X2 with Control-IQ Technology and Dexcom Continuous Glucose Monitor) in closed-loop mode for 8 weeks at home with periodic parameter adjustment driven by an AI-based Advisor system.
