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 Results may not be published yet.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

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

Summary

Researchers are studying whether feeding extremely preterm infants an exclusive human milk diet, with a fortifier made from human milk, affects early signs of blood vessel aging. The trial enrolls about 200 preterm babies weighing 500 to 1250 grams at birth and compares them with term-born children. The team measures blood sugar, blood pressure, and the flexibility of the aorta at ages one, two, and five to see if the type of milk fortifier used in the newborn period makes a lasting difference for heart health.

What this could mean

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

Active substance
an exclusive human milk diet with a human milk-based fortifier
What this could lead to
If it works, this could show that the first diet a preterm baby receives shapes heart and blood vessel health years later, giving hospitals a clear feeding choice to lower long-term cardiovascular risk.
What could go wrong
The trial follows children to age five, so any differences may be small or fade over time, and feeding choices in the NICU are only one of many factors that affect later heart health. Preterm infants face many other health challenges that could outweigh the effect of diet alone.
