Clinical Trial Summary

Subjects will undergo a 7±1 day outpatient, standard therapy phase during which sensor and insulin data will be collected. Subjects or their caregivers will manage their diabetes at home per their usual routine using the study CGM and remain on current MDI or pump therapy. This will be followed by a 5-day/4-night or from approximately 48 to 72 hours for children ages 2.0-5.9 years, hybrid closed-loop phase conducted in a supervised hotel/rental house setting.

Description:

The study schedule will consist of a standard therapy data collection week followed by a hybrid closed-loop phase.

Subjects will undergo a 7±1 day outpatient, standard therapy phase during which sensor and insulin data will be collected. Subjects or their caregivers will manage their diabetes at home per their usual routine using the study CGM and remain on current MDI or pump therapy. This will be followed by a 5-day/4-night or from approximately 48 to 72 hours for children ages 2.0-5.9 years, hybrid closed-loop phase conducted in a supervised hotel/rental house setting.

The hybrid closed-loop phase will begin prior to lunch on Study Day 1.

During the hybrid closed-loop phase, subjects will participate in specific setpoint challenges, meal challenges, and exercise.

Hybrid closed-loop will be discontinued approximately 5 hours after breakfast time on Study Day 5. Subjects will be asked to complete a post-study questionnaire regarding their experience with the system. Subjects will be discharged home when stable and all discharge criteria are met. Subjects will consume a snack or meal after discontinuation of hybrid closed-loop before they leave the study site.

7. Willing to perform all fingerstick BG testing with the study-approved glucose meter at the frequency specified in the study protocol or per investigator discretion

8. Willing to participate in setpoint and meal challenges

9. Willing to use carbohydrate counting for determination of meal boluses

10. Willing to participate in moderate intensity exercise for at least 30 minutes per day

11. Willing to refrain from use of acetaminophen and supplemental vitamin C (>2000 mg/daily) for the entire duration of participation in the study

12. Willing and able to sign the Informed Consent Form (ICF) and/or has a parent/guardian willing and able to sign the ICF. Assent will be obtained from pediatric and adolescent subjects per State requirements.

Exclusion Criteria:

1. One or more episodes of severe hypoglycemia requiring emergency room (ER) visit or hospitalization within the past 6 months

2. One or more episodes of diabetic ketoacidosis requiring ER visit or hospitalization within the past 6 months

3. Planning to start a non-insulin anti-diabetic medication during the study. If on non-insulin medication, dose must be stable in the previous 30 days.

5. 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)

6. 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

7. 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. Abnormal electrocardiogram consistent with increased risk of arrhythmia, ischemia, or prolonged QT interval (> 440 ms). Electrocardiogram is only required for subjects >50 years old or with diabetes duration >20 years.

21. Recent (within the preceding 30 days) participation in a clinical study using an investigational drug

22. Unable to follow the clinical protocol for the duration of the study or is otherwise deemed unacceptable to participate in the study per the investigator's clinical judgment.
