A glucose Monitor's second chance: can it tame type 1 diabetes in High-Risk teens?
NCT ID NCT07742306
First seen Aug 03, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This pilot study tests whether intermittent use of a continuous glucose monitor (CGM), along with regular medical visits, diabetes education, and psychological support, can improve blood sugar control in children and adolescents with high-risk type 1 diabetes in the Dominican Republic. Forty participants aged 10 to 19 will use the Dexcom G7 CGM during two short monitoring periods, then return to usual finger-stick checks. The study will track changes in HbA1c, time in range, glucose variability, and diabetes-related distress to see if this combined approach helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Intermittent use of the Dexcom G7 continuous glucose monitor, combined with pediatric endocrinology follow-up, diabetes education, and psychological support
- What this could lead to
- If effective, this approach could offer a practical, resource-sensitive way to improve glucose control and reduce diabetes distress in high-risk youth, potentially informing broader care in similar settings.
- What could go wrong
- This is a small pilot study with only 40 participants, so results may not apply widely. The intermittent CGM use may not be enough to sustain improvements, and the added visits and support could be hard to maintain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * HbA1c \>9.0% * Age range: 10-19 years * Disposition and availability for patients and families to attend scheduled provider meetings, as well as general diabetic educational and psychological support meetings throughout the whole study. Namely, meeting every 2 weeks for the first 3 months and then every 4 weeks until completion of study for next 12 months. * Willingness and ability to provide signed voluntary consent form. Date and signature is requested however based on literacy levels a patient can provide consent verbally as long as there is a witness who is 18 years or older and demonstration of acknowledgement of information provided. Exclusion Criteria: * Diagnosis of T1D within the past 12 months * Previous or current use of CGM like FreeStyle Libre 2, Dexcom (G6, G7), or similar devices from other companies not mentioned * Current use of continuous insulin pump in combination with CGM use at present or prior to study * Residence location with greater than 3 hours of travel time distance from each health center in setting of cost and feasibility for families to travel on frequent necessary basis * Current steroid therapy orally or intravenously. * Medical comorbidities including chronic renal disease, hemoglobinopathies, leukemia, hematologic or oncologic conditions that can affect glycemia * Pregnancy
