Can we catch type 1 diabetes before it strikes?
NCT ID NCT06676566
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This study tests whether screening children with a high genetic risk for type 1 diabetes, along with regular follow-up and family education, leads to an earlier diagnosis of the disease. Researchers will track 600 children to see if this approach prevents severe symptoms and diabetic ketoacidosis at diagnosis. They will also explore how weight gain, insulin resistance, and physical activity affect disease progression, and whether continuous glucose monitoring can replace traditional glucose tests. The study also examines the psychological impact of knowing a child's risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Screening for islet autoantibodies, regular follow-up, and continuous glucose monitoring (CGM)
- What this could lead to
- If successful, this approach could help catch type 1 diabetes earlier in children, reducing severe complications and improving long-term health.
- What could go wrong
- The study is observational and may not prove that screening improves outcomes. It also requires long-term follow-up, and the psychological impact of knowing a child's risk is a concern.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Children 0 -10 years with high or moderate genetic risk of type 1 diabetes, measured by a combined analysis of HLA and non-HLA SNPs. Moderate genetic risk is defined as 8-10% risk of developing multiple islet autoantibodies before 6 years of age, and high genetic risk as over 10% risk of developing multiple islet autoantibodies before 6 years of age. * Children 0-18 years of age screened in other research studies or tested at a clinical site and found to have a single autoantibody (before stage 1 type 1 diabetes) or multiple islet autoantibodies without or with impaired glucose tolerance (stage 1 or 2 type 1 diabetes, respectively). * Children will be invited to participate in the current study if they have moderate or high genetic risk and 1) have participated in a prevention trial but have dropped out or the trial has ended 2) are not willing to participate in prevention trial. * Children screened and found to be positive for islet autoantibodies in other studies (TEDDY, TrialNet, Innodia etc) or in clinical settings but which have not progressed to stage 3 type 1 diabetes can also be invited to participate in the current study. Exclusion Criteria: * Stage 3 type 1 diabetes * Currently participating in a prevention study
