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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares transfusions using red blood cells from umbilical cord blood versus standard adult donor blood in extremely premature infants. About 176 babies born before 28 weeks or weighing under 1000 grams will be enrolled. The goal is to see if cord blood reduces the risk of serious complications like lung disease, eye problems, or death.

What this could mean

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

Active substance
umbilical cord blood red blood cells
What this could lead to
If it works, this could provide a safer and more effective transfusion option for extremely premature babies, reducing complications like lung and eye problems.
What could go wrong
This is a small pilot study, so results may not be conclusive. Cord blood may not always be available, and the benefits over standard blood are still unproven.

Study facts

What this study's own registry entry says, in plain language.

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 176 people

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

Expected to start

Jan 2027

An estimate. Start dates often move.

Expected to finish

Dec 2029

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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Signed informed consent obtained from parents or legal guardians. * Gestational age at birth \< 28 weeks or birth weight \< 1000 g. * Admission to one of the participating neonatal intensive care units (NICUs) in the Barcelona area. Exclusion Criteria: * Prior red blood cell transfusion during the fetal or neonatal period. * Maternal-fetal immunization (e.g., isoimmunization). * Fetal hydrops. * Major congenital malformations. * Congenital infections. * Immediate need for blood before randomization (e.g., hemorrhagic shock, consumptive coagulopathy). * Participation in another clinical trial that could interfere with the primary outcome.
