This study is a single-arm, observational clinical study that will enroll a maximum of 72 participants.
Participants between the ages of 16+ years with type 1 or type 2 diabetes currently using an insulin pump or receiving basal and bolus multiple daily injections (MDI), with an A1C between 7.5-11.0% at screening, will be recruited for the study.
Two participant groups will be recruited and will participate in up to 4 Phases:
- Group A (Participants with type 1 diabetes) will participate in Phase 1, Phase 2, Phase 3, and Phase 4
- Group B (Participants with type 2 diabetes) will participate in Phase 1, and Phase 4
Phase 1 (Group A and B) will include:
• 14 days of Standard Therapy while using a blinded Dexcom G6 CGM in an outpatient setting
Phase 2 (Group A only) will include:
• 48 hours of using build 1b.x of the Omnipod 5 System in Manual Mode in an outpatient setting
Phase 3 (Group A only) will include:
• 3 day/2 night supervised hotel stay using build 1b.x of the Omnipod 5 System in Automated Mode while also participating in meal and exercise challenges at a defined target glucose setting of 5.6 mmol/L (100 mg/dL). During the first 24 hours, participants will be instructed to not bolus for meals. For the following 24 hours, participants will be instructed to bolus for meals. At least 2 meals each day must contain at least 60 grams of carbohydrates. In addition, each day participants will take part in 45 minutes of exercise.
Phase 4 (Group A and B) will include:
• A total of 6 weeks using the Omnipod 5 System in Automated Mode in an outpatient setting at a defined target glucose setting of 5.6 mmol/L (100 mg/dL). During weeks 1-3, participants will be instructed to bolus for meals. During weeks 4-6, participants will be instructed to not bolus for meals.
After completion of a minimum of 10 participants for Group A, Phase 3, the data will be analysed and must meet prespecified criteria for Group A to proceed to Phase 4 and Group B to proceed to Phase 1 followed by Phase 4.
If the prespecified criteria are not met, software changes will be made and Group A, Phase 3 may be repeated either with the same participants or additional participants that meet the study criteria. Iterations of Group A, Phase 3 may continue until prespecified criteria are met.

Inclusion Criteria-
Participants must meet all the following criteria to be included in the study:
- Age at time of consent 16+ years
- Individuals must be diagnosed with type 1 diabetes based on investigator's clinical judgment for at least 1 year. Individuals diagnosed with type 2 diabetes must be on basal and bolus insulin therapy, with no specified duration.

Exclusion Criteria:
Participants who meet any of the following criteria will be excluded from the study:

- Dermatological conditions at the proposed sensor/pump wear sites that in the investigator's opinion could preclude ability to wear the Pod and/or the Dexcom sensor
- Current or known history of coronary artery disease that is not stable with medical management, including unstable angina, or angina that prevents moderate exercise despite medical management, or a history of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass grafting within the previous 12 months.
