Does longer glucose monitoring help diabetes control? small study halted early
NCT ID NCT03067480
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if using a professional continuous glucose monitor (CGM) for 6 months, instead of 3 months, helps people with poorly controlled type 2 diabetes (who don't use insulin) spend more time with healthy blood sugar levels. Only 12 participants were enrolled before the study was stopped early. The CGM was worn for 3 days at a time and recorded sugar levels without showing them to the patient.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- professional continuous glucose monitor (CGM)
- What this could lead to
- If successful, this could show that longer CGM use helps people with type 2 diabetes better manage their blood sugar without needing insulin.
- What could go wrong
- This was a very small, early study that was terminated before completion. The results may not be reliable or apply to a broader population.
