Description

Inclusion Criteria:

  1. Age 2-6 years at time of screening.
  2. Has a clinical diagnosis of type 1 diabetes for 3 months or more as determined via medical record or source documentation by an individual qualified to make a medical diagnosis.
  3. Parent(s)/guardian(s) is/are literate and able to read the language offered in the pump or pump materials.
  4. Subject or parent(s)/guardian(s) is/are willing to provide informed consent for participation.
  5. Is willing to perform fingerstick blood glucose measurements as needed.
  6. Is willing to wear the system continuously throughout the study.
  7. Must have a minimum daily insulin requirement (Total Daily Dose) of greater than or equal to 6 units on average.
  8. Has a Glycosylated hemoglobin (HbA1c) less than 10% (as processed by Central Lab) at time of screening visit.

    Note: All HbA1c blood specimens will be collected via fingerstick and sent to and tested by a National Glycohemoglobin Standardization Program (NGSP) certified Central Laboratory. HbA1c testing must follow NGSP standards.

  9. Is willing to upload data from the study pump, must have Internet access, and a computer system, or compatible smartphone that meets the requirements for uploading the study pump.
  10. Is willing to take one of the following insulins and can financially support the use of insulin preparations as required by the study per manufacturers labeling:

    1. Humalog (insulin lispro injection)
    2. Authorized generic insulin lispro
    3. NovoLog (insulin aspart injection)
    4. Authorized generic insulin aspart
    5. Admelog (insulin lispro injection) - for subjects aged 3 years and older only
  11. Has 1 month or more of CGM experience at time of screening.
  12. If subject has been diagnosed with hyperthyroidism or hypothyroidism, he/she must have a TSH within 3 months prior to screening or at time of screening.

Exclusion Criteria:

  1. Has a history of 1 or more episodes of severe hypoglycemia during the 3 months prior to screening.
  2. Has been hospitalized or has visited the emergency room (ER) in the 3 months prior to screening resulting with a primary diagnosis of uncontrolled diabetes.
  3. Has had DKA in the last 3 months prior to screening visit.
  4. Will not tolerate tape adhesive in the area of sensor placement as assessed by a qualified individual.
  5. Has any unresolved adverse skin condition in the area of sensor placement (e.g., psoriasis, dermatitis herpetiformis, rash, Staphylococcus infection).
  6. Has diagnosis of adrenal insufficiency.
  7. Has taken any oral, injectable, or intravenous (IV) glucocorticoids within 8 weeks from time of screening visit, or plans to take any oral, injectable, or IV glucocorticoids during the course of the study.
  8. Is using hydroxyurea at time of screening or plans to use it during the study.
  9. Is actively participating in an investigational study (drug or device) wherein he/she has received treatment from an investigational study drug or investigational study device in the last 2 weeks.
  10. Is using pramlintide (Symlin), DPP-4 inhibitor, liraglutide (Victoza or other GLP-1 agonists), metformin, canagliflozin (Invokana or other SGLT2 inhibitors) at time of screening.
  11. Parent(s)/guardian(s) has a history of visual impairment which would not allow subject to participate in the study and perform all study procedures safely, as determined by the investigator.
  12. Has elective surgery planned that requires general anesthesia during the course of the study.
