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.

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.

13. Has sickle cell disease, hemoglobinopathy; or has received red blood cell transfusion or erythropoietin within 3 months prior to time of screening.

14. Plans to receive red blood cell transfusion or erythropoietin over the course of study participation.
