About
A study to compare the glycemic and quality of life benefits of diabetes management using Dexcom G6 continuous glucose monitoring (CGM) or self-monitored blood glucose (SMBG) made by study participants and their primary care physicians. Decisions will be based on insights from real-time use and retrospective insights, determined during remote visits.
Participants will have type 2 diabetes and be using basal insulin (with or without oral medications and/or Glucagon-Like-Peptide-1 (GLP-1) analogue) and have an elevated Hemoglobin A1C (HbA1c).
Full description
The study is referred to as the "Continuous Glucose MOnitoring in T2D Basal InsuLin UsErs, also known as The MOBILE Study" and will assess potential benefits of using Continuous Glucose Monitoring (CGM) versus traditional Blood Glucose Monitoring (BGM) in people with Type 2 Diabetes using basal insulin with or without oral medications and who have an elevated HbA1c between 7.8 -11.5%. In this study, the investigator's role is largely advisory, providing insights and interpretations of the glucose data obtained from BGM or CGM devices and formally communicating medication recommendations to the participant and their treating community clinician. Participants will be recruited from outside of the investigator team's diabetes and endocrine practice.
The protocol comprises of 2 studies: the 1st study (also called Phase 1) will evaluate the values of CGM after eight months of use. The 2nd study (also called Phase 2) will evaluate if any glycemic benefits attained in study one are sustainable for an additional six months.
At the time of enrollment, participants will undergo a run-in period of blinded CGM for a duration of 10 days. Baseline Patient Report Outcome (PRO) tools and surveys will be administered at time of enrollment.
The study design includes two phases. During Phase 1, participants with T2D taking basal insulin will be randomized into two groups - CGM Group or SMBG Group. Phase 1 is of 8 months duration. The CGM group will comprise of 4 scheduled clinic visits: at week 2, month 1, month 3, and month 8. The SMBG group will comprise of 5 scheduled clinic visits: at week 2, month 1, month 3, pre-month 8 and month 8. Both groups will have structured phone/remote visits at months 2, 4 and 6 during which glucose data will be reviewed and summarized. HbA1c will be measured at baseline, 3 months and 8 months. Participants will complete PRO tools and surveys at 8 months.
Phase 2 will consist of 3 groups: participants continuing use of SMBG since the beginning of Phase 1; participants re-randomized from the Phase 1 CGM Group and assigned to SMBG; participants re-randomized from Phase 1 CGM Group and assigned to CGM. Phase 2 duration is 6 months. This phase involves 1 phone contact and either 2 visits at Month 14 for SMBG participants to wear blinded CGM or one visit for CGM participants. HbA1c will be measured at 14 months. Participants will complete PRO tools and surveys at month 14. For all participants, study participation will end upon completion of month 14 visit .
