Can a simple monitor predict type 1 diabetes before symptoms start?

NCT ID NCT05777330

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study is testing whether a continuous glucose monitor (CGM) can predict blood sugar problems in people who are at risk for type 1 diabetes but have no symptoms. Researchers will follow 75 people aged 5 to 39 who have diabetes-related autoantibodies. They will compare CGM data with standard tests like oral glucose tolerance tests and hyperglycemic clamps over 2-3 years to see if the monitor can catch early signs of diabetes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simpler way to detect early signs of type 1 diabetes using a continuous glucose monitor instead of frequent lab tests.
What could go wrong
This is an observational study, not a treatment trial. It may not find a clear link between CGM readings and disease progression, and results may not apply to all risk groups.
