NCT ID NCT05789251

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 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 Results may not be published yet.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.

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.

Summary

This trial explores whether a standardized breakfast and a continuous glucose monitor can replace the traditional glucose drink test for diagnosing diabetes and prediabetes in people with Dunnigan's lipodystrophy, a rare genetic condition that causes severe insulin resistance. The study will compare the breakfast test and sensor readings against the standard oral glucose tolerance test to see if they agree. If they do, it could offer a more comfortable and practical way to monitor these patients, potentially improving adherence to regular check-ups.

What this could mean

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

Active substance
Standardized breakfast and continuous interstitial glucose monitoring
What this could lead to
If successful, this could offer a more acceptable alternative to the standard glucose drink for diagnosing diabetes in people with Dunnigan's lipodystrophy, improving follow-up and early detection.
What could go wrong
This is a small, early-stage study. The breakfast may not match the glucose drink's accuracy, and continuous monitoring might not align perfectly with standard tests. Results may not apply to other populations.
