Continuous Glucose Monitoring in T2D Basal Insulin Users: The MOBILE Study

University of North Carolina at Chapel Hill


The primary purpose of this research is to assess the benefit on glycemic control, using real time continuous glucose (CGM) versus self monitored blood glucose (SMBG/finger sticks), in persons with Type 2 Diabetes (T2D) taking basal insulin (long-acting) with or without oral medications and/or GLP-1 analogue, not at their HbA1c goal. Secondary objectives are to assess quality of life benefits of RT-CGM and to assess frequency of hypoglycemia. The Phase 2 primary objective is to determine if glycemic control worsens upon withdrawal of RT-CGM. Secondary objectives are to determine if glycemic benefits of RT-CGM use are sustainable for a long period of time (14 months), to assess QoL benefits of continuing or discontinuing RT-CGM, and to assess frequency of hypoglycemia.







18 - 99 years


Study Population

Adult T2D patients followed by a primary care physician, who are currently on basal insulin therapy with or without oral anti-diabetic therapy and/or GLP-1 analogue injections and who are sub-optimally controlled. Participants will be recruited from within the network or the referral base of the research site.
