An interventional study of Dexcom G6 in Diabetes Type 2, sponsored by University of Washington. Completed at 2 sites in United States. Open to participants aged 18 Years to 60 Years. Per ClinicalTrials.gov, last updated 2025-12-01.

Determine the impact of the Compañeros en Salud (Partners in Health) curriculum in conjunction with RT-CGM on glycemic control in Latinx patients with T2D. Participants will be randomized to receive the Companeros en Salud diabetes self-management education and support (DSMES) intervention with or without RT-CGM
The prevalence of type 2 diabetes is increasing especially in the Latinx community and in family members of those already living with diabetes. Diabetes education is a cornerstone of treatment but is often not culturally tailored and there is limited data on benefit of virtual delivery of sessions. Real Time Continuous glucose monitoring is a tool to improve diabetes but is not readily available to those living with type 2 diabetes not on multiple doses of insulin. Furthermore here is little to no data on RT-CGM use in different minority populations. Data is also lacking on if diabetes education for an individual affects the family unit. We hypothesize that culturally tailored Diabetes self-management education using and support (DSMES) using a team approach of health educators and Community health workers will improve glycemic indices. We further hypothesis that RT-CGM coupled to DSMES will enhances glycemic benefit and change nutrition and activity behaviors. This will be a randomized control trial of 100 Latinx participants who will all receive culturally tailored DSMES with or without cycle RT-CGM over 12 weeks. Primary outcome will be mean A1C improvement at 12 and 24 weeks based on attendance of sessions and RT-CGM use. Secondary outcomes will be satisfaction with education and CGM, changes in weight, blood pressure and self-reported nutrition and exercise changes. This study will be the first study to examine how DSMES with and without RT-CGM use improves health outcomes in the Latinx population and their families

Time frame: baseline
PHQ9 Depression Score- Those With PHQ9>15
Scores less than 5 almost always signified the absence of a depressive disorder; scores of 5 to 9 predominantly represented patients with either no depression or subthreshold (i.e., other) depression; scores of 10 to 14 represented a spectrum of patients; and scores of 15 or greater usually indicated major depression.
Time frame: 12 weeks

The Summary of Diabetes Self-Care Activities asks patient about diabetes self-care activities during the past 7 days and for each activity they can answer 0 days out of the week to a max of 7 days out of the week with higher score indicating more days doing this self -care activity and positive results
Time frame: composite score at 12 weeks
Modified Joslin Diabetes Center CGM Experience
Experiences of CGM @Joslin 2009 scale range from 5 (strongly agree) to 1 ( strongly disagree) statements/questions that measured the amount of satisfaction that was derived from use of continuous glucose monitoring. Higher score meant perceived benefit/ better outcome
