Omnipod® 5 Automated Insulin Delivery System in Patients With Type 2 Diabetes

The study subjects will be separated into 2 groups, depending on their previous insulin therapy with approximately 50% of subjects from each group, continuous glucose monitoring (CGM) naive.

Group A will complete a 2-week Standard Therapy Phase followed by 8 weeks of Omnipod 5 system use.

Group B will complete a 2-week Standard Therapy Phase followed by 10 weeks of Omnipod 5 system use.

Group A and Group B will have an optional 6-month extension of Omnipod 5 system use

Basal-Bolus - Group A (N=12)

* 2 weeks standard therapy - using multiple daily injections (MDI) and Dexcom G6 continuous glucose monitoring (CGM) , followed by:
* 4 weeks Omnipod 5 system use in Automated Mode with optional bolus, followed by:
* 4 weeks Omnipod 5 system use in Automated Mode with simplified bolus
* 6-month optional extension using Automated Mode

Basal - Group B (N=12)

* 2 weeks standard therapy - using basal injection only and Dexcom G6 continuous glucose monitoring (CGM) , followed by:
* 2 weeks Omnipod 5 system use in Manual Mode with Dexcom G6 continuous glucose monitoring (CGM) - with fixed basal rate, no bolus, followed by:
* 4 weeks Omnipod 5 system use in Automated Mode with optional bolus, followed by:

  * If % time in range 70-180 mg/dL during Automated Mode is ≤50%, 4 weeks Omnipod 5 system use in Automated Mode with simplified bolus, OR
  * If % time in range 70-180 mg/dL during Automated Mode is \>50%, 4 weeks Omnipod 5 system use in Automated Mode with optional bolus
* 6-month optional extension using Automated Mode
