Brief summary
Subject will undergo a 14-day outpatient, standard therapy phase during which sensor and insulin data will be collected. This will be followed by a 90-day outpatient phase where subjects will either use the Omnipod 5 system or continue to use their personal insulin pump with the study provided continuous glucose monitoring system. Participants in France will be offered an optional extension of 12 months of Omnipod 5 System use.
Detailed description
This is an outpatient study that consists of two phases, Phase 1 and Phase 2. There will be approximately 8 study visits conducted in person or via telehealth. Phase 1 is a 14-day period to collect baseline sensor and insulin data where subjects will manage their diabetes at home per their usual routine using the study continuous glucose monitoring system. Phase 2 is a 90-day period where subjects will be randomized into one of two groups. One group will use the Omnipod 5 system and the other group will continue to use their personal insulin pump with the study continuous glucose monitoring system. Following the 90-day outpatient phase, participants in France will be offered the option to transition to use the CE-marked commercial Omnipod 5 System for an additional 12 months with the French interface.
Interventions
Omnipod 5 System automates insulin delivery based on information received from the continuous glucose monitoring system every 5 minutes.

Inclusion criteria
1. Age at time of consent 18-70 years of age 2. Diagnosed with type 1 diabetes for at least 1 year. Diagnosis is based on investigator's clinical judgment. 3. On pump therapy for ≥ 3 months prior to screening and familiar with pump therapy concepts such as basal and bolus insulin delivery, and carbohydrate counting. Participants using automated insulin delivery (AID) devices, including devices with predictive low glucose suspend (PLGS), in the 3 months prior to screening, will be excluded from participating. 4. A1C 7.0-11.0% by point-of-care taken at screening visit 5. Willing to use and obtain U-100 insulin: (either insulin aspart (Novolog, NovoRapid), or insulin lispro (Humalog, Admelog)), as the primary insulin treatment 6.

Exclusion criteria
1. Any medical condition, such as untreated malignancy, unstable cardiac disease, unstable or end-stage renal failure, eating disorders, or other conditions which in the opinion of the investigator, would put the participant at an unacceptable safety risk 2.
