What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether extending nightly sleep by about 2 hours in adults who habitually sleep less than 6.5 hours can improve insulin sensitivity and reduce cardiometabolic risk. Participants are overweight or obese adults aged 18-45 without diabetes or sleep disorders. They are randomly assigned to either a sleep extension intervention or a healthy lifestyle control group, with outcomes including changes in plasma ceramides and insulin sensitivity.

What this could mean

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

Active substance
Sleep extension intervention (behavioral)
What this could lead to
If successful, this could show that simply sleeping more improves insulin sensitivity and reduces cardiometabolic risk in short sleepers, potentially informing lifestyle-based prevention strategies.
What could go wrong
The trial is relatively small and early-stage, and results may not apply to all populations. Adherence to the sleep extension may vary, and the intervention may not produce significant metabolic changes.
