This study's is highlighted.

Recruitment status, easiest to join first

Recruiting 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.

Ongoing This study
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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

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 study tests whether keeping a consistent daily routine—like eating and sleeping at the same times—can improve blood sugar control and reduce body fat in people with pre-diabetes. Researchers will enroll 34 adults and ask half to follow a fixed schedule for 12 weeks. The goal is to see if this simple lifestyle change is feasible and effective for managing pre-diabetes.

What this could mean

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

Active substance
fixed daily schedule (behavioral intervention)
What this could lead to
If it works, this could point toward a simple, drug-free way to help manage pre-diabetes and reduce diabetes risk.
What could go wrong
This is a very small, early feasibility study with only 34 people. Results may not apply to everyone, and sticking to a fixed schedule may be hard for some.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
