Use of Continuous Glucose Monitors in Publicly-Insured Youth With Type 2 Diabetes - A Pilot and Feasibility Study

July 9, 2024 updated by: Sejal Shah, Stanford University
The purpose of this pilot feasibility study is to provide continued CGM access to youth with type 2 diabetes and collect descriptive data about feasibility of use of CGM in youth with type 2 diabetes ages 4 years and older. From this study the investigators hope to learn if CGM use in youth with type 2 diabetes can be tolerated and sustained with good adherence and to describe blood glucose patterns in youth with type 2 diabetes. The primary aim will be to evaluate the feasibility of CGM start and continuation in youth with T2D and describe glucose metrics and patient reported outcomes (PROs). The investigators will pilot and refine a program to test the hypothesis that CGM start and continuation in youth with T2D is feasible and then evaluate glucose metrics and PROs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of Participants With at Least 75% Wear Time Over 14 Days as a Measure of Sustained CGM Use
Time Frame: months 2,3,6,9 and 12 (assessed over the 14 days prior to each clinic visit)
months 2,3,6,9 and 12 (assessed over the 14 days prior to each clinic visit)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean HbA1C
Time Frame: baseline and months 2,3,6,9 and 12
HbA1C through 12 months of CGM use
baseline and months 2,3,6,9 and 12
Time With Glucose Values in Target Range of 70-180 mg/dL
Time Frame: months 2,3,6,9 and 12 (assessed over the 14 days prior to each clinic visit)
months 2,3,6,9 and 12 (assessed over the 14 days prior to each clinic visit)
PROMIS Global Health Overall Scale Score
Time Frame: baseline, months 3 and 12
PROMIS Global Health (7 questions, Minimum=1, maximum=5 for each question, higher score for physical health questions is better outcome, higher score for mental health is worse outcome). Scores for each question were summed then converted to a t-score (overall range 16 to 67.5, higher score = better health). A score of 50 is the average for the United States general population with a standard deviation of 10. A score below 22 in this study would result in a referral to social work or diabetes psychology.
baseline, months 3 and 12
PedsQL 3.2 Overall Scale Score - Participant Rated
Time Frame: baseline and months 3 and 12
Pediatric Quality of Life Inventory (PedsQL) Diabetes Module version 3.2, including 33 items (questions) comprising 5 dimensions (diabetes symptoms, treatment 1, treatment 2, worry, and communication). Each item scored from 0 to 4, higher scores correspond to lower problems. Each item is reversed scored and linearly transformed to a 0 to 100 scale (0=100,1=75,2=50,3=25,4=0), higher scores correspond to lower problems. The overall score is calculated as the sum of the transformed scores for each item divided by the total number of items answered by participants to create an overall score range of 0 to 100, higher scores correspond to lower problems.
