Effect of donor milk or formula and fortification strategies on outcomes in very preterm infants
Official title: The Effects of Different Enteral Feeding Regimens on Necrotizing Enterocolitis, Mortality, and Neurodevelopment in Very Preterm Infants: A Multicenter Double-Randomized Trial
Run by The Children's Hospital of Zhejiang University School of Medicine · NCT07045844 · Data updated 2026-11-12
In very preterm babies, the study tests whether supplementing the infant's mother's milk with pasteurized donor milk or preterm formula, and using routine versus selective fortification, can improve survival without NEC and support development.

Is this trial a fit for you?
✓Likely a good fit
Infants born at less than 29 weeks gestation whose mothers are willing to breastfeed and whose enteral feeding is feasible.
✕Probably not a fit
Infants with contraindications to enteral feeding or whose families choose exclusive formula or otherwise non-standard feeding plans may not benefit.

What this trial studies
This interventional study randomizes infants born before 29 weeks gestation to receive either pasteurized donor human milk or preterm formula when maternal milk is insufficient. It also compares routine fortified human milk to selective fortification based on growth needs. The primary goal is to see if these feeding strategies improve survival without surgery-requiring NEC by 34 weeks gestational age, and to determine which fortification approach best supports growth and neurodevelopment. Participants are assigned in two randomization steps within the first week of life. The trial is conducted across multiple Chinese and UK sites with international collaboration.
Why it matters
Potential benefit: If successful, the feeding strategies could reduce NEC risk and improve growth and neurodevelopment in very preterm infants.
How similar studies have gone: Prior work in very preterm infants supports the idea that human milk and fortification strategies influence NEC risk and growth, though specific double-randomization of donor milk/formula and fortification approach is innovative.

Inclusion Criteria: * Gestational age at birth less than 29 weeks; * No contraindications to enteral feeding; * Mother is willing to breastfeed. Exclusion Criteria: * For Randomization Group 1: If the infant has already received pasteurized human donor milk (pHDM), preterm formula (PTF), or nutritional fortifiers; * For Randomization Group 2: If the infant is exclusively fed with preterm formula and the mother has no intention to express breast milk;
