Could a High-Protein diet in the NICU boost preemie brain development?
NCT ID NCT04190875
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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 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.
