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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks at whether using a continuous glucose monitor (CGM) alongside standard nutrition and activity advice can improve metabolic health in young people aged 11 and older who have prediabetes and are overweight. Participants wear the CGM intermittently to see how daily activities affect their blood sugar. The study measures changes in blood sugar control (HbA1c) and insulin resistance over six months.

What this could mean

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

Active substance
Abbott Freestyle Libre 2 continuous glucose monitor
What this could lead to
If successful, this approach could offer a practical tool to help young people with prediabetes better manage their condition and prevent progression to type 2 diabetes.
What could go wrong
This is a small, early-stage study (54 participants) focused on feasibility and short-term changes, so results may not apply broadly. The device itself is not a treatment and carries minor risks like skin irritation.
