Ages Eligible for Study:   6 Years to 65 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Subjects must meet all of the following criteria to be included in the study:

  3. Total daily dose (TDD) of insulin ≥ 0.3 units/kg/day and A1C > 6% at screening
  4. Currently using an insulin pump with U-100 rapid-acting insulin analogs and on pump for at least 6 months prior to start of study
  5. Willing to use the study CGM device for one week prior to study start and for the duration of the study
  6. Willing to use the OmniPod® Insulin Management System during the study
  7. Willing to perform all SMBG testing with the study-approved glucose meter at the frequency specified in the study protocol
  8. Willing to abide by meal recommendations for breakfast, lunch and dinner during the study
  9. Willing to refrain from use of acetaminophen, pseudoephedrine, and supplemental vitamin C (>2000 mg/daily) for the entire duration of participation in the study
  10. Willing and able to sign the Informed Consent Form (ICF) and/or has a parent or guardian willing and able to sign the ICF. Subjects aged ≥ 8 years will be asked to sign an assent form.

Exclusion Criteria:

Subjects who meet any of the following criteria will be excluded from the study:

  1. A1c >10% at the Screening visit
  2. One or more episodes of severe hypoglycemia requiring emergency room (ER) visit or hospitalization within the past 6 months

  4. One or more episodes of diabetic ketoacidosis requiring ER visit or hospitalization within the past 6 months
  5. Used non-insulin anti-diabetic medication within last 30 days
  6. Pregnant or lactating, or is a woman of childbearing potential and not on acceptable form of birth control (acceptable includes abstinence, condoms, oral/injectable contraceptives, IUD or implant)
  7. Dermatological conditions at the proposed sensor wear sites that in the investigator's opinion could preclude ability to wear the Pod and/or the Dexcom sensor on the abdomen
  8. Known history of myocardial infarction (MI) or stroke within the past 6 months
  9. Known history of seizure disorder
  10. Known history of adrenal insufficiency
  11. Current renal or hepatic disease
  12. Untreated or unstable hypothyroidism or celiac disease (per investigator's judgment)
  13. Currently undergoing cancer treatment
  14. Currently undergoing systemic treatment with steroids or immunosuppressive medication
