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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether feeding preterm infants breast milk at the same time of day it was expressed can improve their sleep in the NICU. Researchers will compare this circadian-synchronized feeding approach to routine feeding in 120 preterm infants born between 28 and 36 weeks. Sleep patterns will be measured using a wearable EEG patch and sleep mat at 37 weeks corrected age.

What this could mean

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

Active substance
Circadian-synchronized breast milk feeding (behavioral intervention)
What this could lead to
If it works, this could offer a simple, drug-free way to improve sleep and help preterm infants develop healthier sleep patterns in the NICU.
What could go wrong
This is a small, early-stage trial with only 120 infants. The feeding approach may not significantly improve sleep, and results may not apply to all preterm infants.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 120 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Sep 2026

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.
