Scientists hunt for clues to predict type 1 diabetes in kids

NCT ID NCT07627230

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This completed study followed over 1,000 children with newly diagnosed type 1 diabetes and their healthy siblings for up to three years. Researchers collected genetic information, measured diabetes-related antibodies, and asked about environmental exposures. The goal was to build a model that could predict which healthy siblings might develop the disease. No treatment was tested; this was purely an effort to better understand risk factors.

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 research could help identify children at high risk for type 1 diabetes before symptoms appear, allowing for earlier monitoring or prevention strategies.
What could go wrong
This is an observational study, not a treatment trial, so it does not test any intervention. The prediction model may not be accurate enough for widespread use, and results may not apply to all populations.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population included children with newly diagnosed type 1 diabetes mellitus and their healthy biological siblings recruited between October 2017 and June 2021. Healthy siblings had no laboratory evidence of type 1 diabetes at enrollment and were followed prospectively to assess the risk of disease development.

Ages

4 months to 29 years

Sex
