Breast milk from donors vs. formula: which builds a better brain for tiny babies?
NCT ID NCT01534481
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study tests whether extremely low birth weight infants (born before 29 weeks) who receive donor human milk during their hospital stay have better brain development than those given preterm formula. Infants whose mothers cannot or choose not to breastfeed are randomly assigned to one of the two diets. Their cognitive skills are measured at 22 to 26 months of age using the Bayley Scales of Infant Development.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- donor human milk or preterm formula
- What this could lead to
- If donor milk improves brain development, it could become the standard diet for extremely low birth weight infants whose mothers cannot provide breast milk.
- What could go wrong
- This is a single trial with 483 infants, and results may not apply to all hospitals or populations. Donor milk is costly and may not show a clear advantage over formula.

Inclusion Criteria: * Gestational age less than 29 weeks. * Admitted to the NICU at less than or equal to 72 hours of life * Survived at least 12 hours Exclusion Criteria: * Chromosomal anomalies * Cyanotic congenital heart disease * Diagnosed intrauterine infection * Other congenital disorders known to impair neurodevelopment * NEC or IP prior to seeking consent * Decision documented to limit intensive care therapies * Congenital disorders that may affect feeding Feeding Group Eligibility: * Sole Diet Group: Infants will be eligible for the sole diet feeding protocol if the mother declines to provide breast milk for the baby. * Supplemental Diet (minimal maternal milk) Group: Infants whose mothers initially choose to provide breast milk and begin pumping will be re-screened for eligibility at least weekly until the infant is 21 days old. If the mother stops expressing milk at any point prior to the infant's 21st day of life, her infant will be eligible for randomization. In addition, those whose mothers are providing less than 20% of the infant's dietary needs (averaged over past 5 days) when the infant reaches 21 days of age will be eligible for randomization at this point. No infant will be randomized after reaching 21 days.
