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 Results may not be published yet.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.

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 follows up on extremely low birth weight infants (under 1000 grams) who received either a standard or high-protein diet while in the NICU. Researchers want to see if the higher protein diet leads to better growth, body composition, and neurodevelopment at 18-24 months of age. The study is currently suspended.

What this could mean

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

Active substance
high-protein diet (targeted fortification of human milk)
What this could lead to
If successful, this could show that a higher protein diet in the NICU leads to better long-term growth and brain development in extremely premature infants.
What could go wrong
This is a small, suspended follow-up study, so results may not be conclusive. The diet was given in the NICU, and many other factors affect a child's development.

Who can take part

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

Who is studied

Children 18-24 months corrected age, who participated in an earlier study H-38611. These children were either born at Texas Children's Hospital in the first 24 hours of life and admitted to our Neonatal Intensive Care Unit. These infants had a birth weight of less than or equal to 1000 grams and were randomized to receive a standard protein diet (3.5-3.8 grams of protein per kilogram of body weight) or a high protein diet (4.2-4.5 grams of protein per kilogram of body weight). Infants in both groups received recommended clinical guidelines for protein.

Inclusion Criteria: * Children born prematurely, with birth weight of less than or equal to 1000 grams * Born at Texas Children's Hospital or transferred to the Neonatal Intensive Care Unit from another hospital in the first 24 hours of life * Completed a previous study (H-38611) in which the child received targeted protein fortification with donor human milk products Exclusion Criteria: * Infants not previously enrolled in a previous study (H-38611) in the Neonatal Intensive Care Unit at Texas Children's Hospital * Infants enrolled in but did not complete a previous study (H-38611) in the Neonatal Intensive Care Unit at Texas Children's Hospital
