Brief Summary:
Evaluate safety of non-adjunctive CGM use in CGM naive participants.

Condition or disease Intervention/treatment
Diabetes Device: Continuous Glucose Monitoring (CGM)

Detailed Description:
The study comprises recruitment and consenting of pediatric and adult participants. At entry, the following information will be collected: demographics, labs, clinical and diabetes history information (history of mild/severe hypoglycemia or DKA events in the past 6 months and SMBG testing frequency). There are 3 clinic visits: Study Entry, Month 6 and Month 12 . Monthly phone contacts will be made to assess for any mild/severe hypoglycemic or DKA events and any details surrounding an event. Clinic visits at Months 6 and 12 will capture frequency of SMBG testing, A1C level and PRO information. CGM data will be obtained during the study to assess for CGM adherence.

Group/Cohort Intervention/treatment
CGM/BGM Group
single-group, whereby participant is their own control. Use of a Blood Glucose Meter (BGM) for 6 months is compared to use of the G5 and G6 CGM System for 6 months, with collection of major diabetes related events (mild/severe hypoglycemia and DKA).
Device: Continuous Glucose Monitoring (CGM)
Use of CGM to compare incidence of diabetes events compared to use of a blood glucose meter (BGM)




Primary Outcome Measures :
  1. Change in hypoglycemic events [ Time Frame: 6 months ]
    Change in average number of hypoglycemic events per patient between CGM use compared to BGM use


Secondary Outcome Measures :
  1. Change in A1C [ Time Frame: 6 months ]
    Percent change in A1C lab between CGM use period compared to BGM use period.

  2. Change in incidence of hypoglycemic events [ Time Frame: 6 months ]
    Percent change of participants with at least one event between CGM use period compared to BGM use period.

  3. Change in GMSS PRO scores [ Time Frame: 6 months ]
    Percent change in mean scores for the Glucose monitoring satisfaction survey (GMSS) [Emotional and Trust subscales] between CGM use period compared to BGM use period.

  4. Change in Diabetes Distress Scale (DDS) PRO scores [ Time Frame: 6 months ]
    Percent change in mean scores for the DDS between CGM use period compared to BGM use period.

  5. Change in Hypoglycemia Fear PRO scores [ Time Frame: 6 months ]
    Percent change in mean scores for the Hypoglycemia Fear Survey between CGM use period compared to BGM use period.

  6. Change in Hypoglycemia Confidence PRO scores [ Time Frame: 6 months ]
    Percent change in mean scores for the Hypoglycemia Confidence Scale between CGM use period compared to BGM use period.
