Brief Summary:
Subjects will undergo a 14-day outpatient, standard therapy phase during which sensor and insulin data will be collected. This will be followed by a 91-day (13-week) hybrid closed-loop phase conducted in an outpatient setting.

Condition or disease Intervention/treatment Phase
Type 1 Diabetes Mellitus Device: Omnipod Horizon™ Automated Glucose Control System Not Applicable

Detailed Description:

The study schedule will consist of a standard therapy data collection phase followed by a hybrid closed-loop phase.

Subjects will undergo a 14-day outpatient, standard therapy phase during which sensor and insulin data will be collected. Subjects, or their caregivers, will manage their diabetes at home per their usual routine using the study continuous glucose monitoring system (CGM) and remain on current multiple daily injections (MDI) or pump therapy. This will be followed by a 91-day (13-week) hybrid closed-loop phase conducted in an outpatient setting.

During the hybrid closed-loop phase, a subset of subjects will participate in 5-days of supervised meal and exercise challenges.

The hybrid closed-loop phase will begin on Study Day 1.
