Study summary

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

Read the 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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Naïve to real-time CGM
  • Type 1 or insulin-requiring Type 2 diabetes
  • ≥ 2 years old

Exclusion criteria

Exclusion Criteria:

  • Use of RT-CGM, within the past 12 months
  • Pregnancy
  • Concomitant disease or condition that may compromise patient safety including and not limited to severe mental illness, a diagnosed or suspected eating disorder or any uncontrolled long term medical condition that would interfere with study related tasks or visits, or ongoing treatment for a significant .
  • Known (or suspected) significant allergy to medical grade adhesives
  • Dialysis
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Groups and cohorts

  • 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)

Interventions

  • DeviceContinuous Glucose Monitoring (CGM)

    Use of CGM to compare incidence of diabetes events compared to use of a blood glucose meter (BGM)

    Percent change of participants with at least one event between CGM use period compared to BGM use period.

    Time frame: 6 months

  3. Change in GMSS PRO scores

    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.

    Time frame: 6 months

  4. Change in Diabetes Distress Scale (DDS) PRO scores

    Percent change in mean scores for the DDS between CGM use period compared to BGM use period.

    Time frame: 6 months

  5. Change in Hypoglycemia Fear PRO scores

    Percent change in mean scores for the Hypoglycemia Fear Survey between CGM use period compared to BGM use period.

    Time frame: 6 months

  6. Change in Hypoglycemia Confidence PRO scores

    Percent change in mean scores for the Hypoglycemia Confidence Scale between CGM use period compared to BGM use period.

    Time frame: 6 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2017 (actual). Primary completion is estimated for Dec 2023, 74 months after the start.

Of 109 industry-sponsored observational studies under Diabetes Mellitus, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 39. This study's planned 74 months is above that.

Counting every sponsor, half of 642 studies reached it within 36 months; a quarter within 14 and three quarters within 122.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 21, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
