Clinical Trial Summary

The central hypothesis of this clinical trial is that, in extremely preterm infants, protein-enriched human milk diets compared to usual human milk diets during the first 2 weeks after birth increase fat-free mass (FFM)-for-age Z scores and promote maturation of the gut microbiome at term corrected age.

Description:

Masked randomized clinical trial in which extremely preterm infants fed human milk will be randomly assigned to receive either a protein-enriched diet (intervention group) or a usual diet (control group) within the first 96 hours after birth.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes in Intestinal Microbiome	Determined by molecular analyses of fecal samples	Birth to 36 weeks postmenstrual age
Other	Cognitive Outcomes	Determined by Bayley assessment	2 years of corrected age
Primary	Fat-free Mass(FFM)-For-age Z-score	Estimated by air displacement plethysmography. FFM measurements were converted into Z-scores using updated, sex-specific reference curves of body composition in preterm infants (Norris et al, 2019). A Z-score of 0 represents the population mean. Z-score values closer to 0 represent a better outcome. No relevant thresholds have been defined.	36 weeks or hospital discharge, up to 120 days following birth, whichever is longer
Secondary	Fat Mass(FM)-For-age Z-score	Estimated by air displacement plethysmography. FM measurements were converted into Z-scores using updated, sex-specific reference curves of body composition in preterm infants (Norris et al, 2019). A Z-score of 0 represents the population mean. Z-score values closer to 0 represent a better outcome. No relevant thresholds have been defined.	36 weeks or hospital discharge, up to 120 days following birth, whichever is longer
Secondary	Body Fat(BF)-For-age Z-score	Body fat estimated by air displacement plethysmography. BF measurements were converted into Z-scores using updated, sex-specific reference curves of body composition in preterm infants (Norris et al, 2019). A Z-score of 0 represents the population mean. Z-score values closer to 0 represent a better outcome. No relevant thresholds have been defined.	36 weeks or hospital discharge, up to 120 days following birth, whichever is longer
Secondary	Anthropometric Measurements	Weight, length, and head circumference measurements. Measurements were converted into Z-scores based on Fenton growth curves (2013). They were calculated at birth and at 36 weeks. This outcome represents the change in weight, length, and head circumference Z-score during the course of the study (i.e., the Z-score at birth was subtracted from the Z-score at 36 weeks).; A value of 0 represents that the infant's Z-score is the same at the beginning and the end of the study. Positive values indicate the increase in the infant's Z-score during the study; negative values indicate the decrease in the infant's Z-score during the study.	Birth to 36 weeks postmenstrual age or hospital discharge (whichever occurred first)
Secondary	Growth Rate	Weight gain in g/kg/day	Birth to 36 weeks postmenstrual age or hospital discharge (whichever occurred first)
Secondary	Number of Participants With Postnatal Growth Failure	Diagnosis of growth failure (weight < 10th percentile using the 2013 Fenton growth curves)	36 weeks or hospital discharge (whichever occurred first)
Secondary	Number of Participants With Diagnosis of Necrotizing Enterocolitis	Diagnosis of necrotizing enterocolitis stage 2 or 3	From birth up to 120 days following birth
Secondary	Number of Participants With Diagnosis of Intestinal Perforation	Diagnosis of intestinal perforation	From birth up to 120 days following birth
Secondary	Death	Death prior to 121 days of life	Birth to 120 days
Secondary	Culture-proven Sepsis	Diagnosis of sepsis with positive blood cultures	Birth to 120 days
Secondary	Number of Days Alive and Receiving Full Enteral Feeding	Time to full enteral feeding days	Birth to 28 days

Secondary	Duration of Hospital Stay in Days	From day of admission to day of hospital discharge to home	Birth to 120 days or discharge, whichever occurs first
Secondary	Serum BUN	Highest serum BUN value in the first 28 days after birth	Birth to 28 days
