Switching from intermittently scanned to real-time continuous glucose monitoring for diabetes management

Effect of Switching From Intermittently Scanned Continuous Glucose Monitoring to Real-time Continuous Glucose Monitoring on Glycemic Outcomes in Adults With Type 2 Diabetes

Observational LMC Diabetes & Endocrinology Ltd. · NCT06805786

This study is testing if switching from a type of glucose monitor that you check occasionally to one that gives real-time readings helps adults with insulin-treated type 2 diabetes manage their blood sugar better.

What this trial studies

This observational study aims to evaluate the impact of switching from intermittently scanned continuous glucose monitoring (isCGM) to real-time continuous glucose monitoring (rtCGM) on diabetes management in adults with insulin-treated type 2 diabetes. Participants will be followed for 3-6 months to assess changes in time in range (TIR) and other glycemic outcomes. The study compares outcomes between those who switch to rtCGM and those who continue using isCGM. It is conducted in a specialist endocrinology clinic in Canada.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a clinical diagnosis of type 2 diabetes who have been using insulin for at least 6 months and currently using a FreeStyle Libre® 2 isCGM device.

Not a fit: Patients who have used real-time continuous glucose monitoring within the past 12 months or are expecting changes in their antihyperglycemic medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve diabetes management and glycemic control for patients using continuous glucose monitoring.

How similar studies have performed: Other studies have shown positive outcomes with continuous glucose monitoring approaches, suggesting potential success for this study as well.
