- Conditions
- Gastrointestinal Complication, Intestinal Obstruction, Gastroschisis, Hirschsprung Disease, Omphalocele, Midgut Volvulus

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standard of CareDietary supplement
Standard of care arm: Mothers will consent to providing DHM (if qualifies per hospital policy) or formula if MOM is not available. Infants are only eligible to receive donor milk only if 1) MOM is not available 2) if infant initiates feeds before day 3 of age. The donor milk feed would be stopped on day 5 of age.
Exclusive Human MilkDietary supplement
Mothers will consent to providing DHM if MOM is not available. If the infant reaches 100 ml/kg/day of feeds (one feed advancement prior to full feeds) and MOM remains unavailable, they will transition to formula in preparation for discharge. Infants cannot be discharged on donor milk.

| Exclusive human milk | Experimental | Mothers will consent to providing DHM if MOM is not available. If the infant reaches 100 ml/kg/day of feeds (one feed advancement prior to full feeds) and MOM remains unavailable, they will transition to formula in preparation for discharge.

| Standard of care | Experimental | Mothers will consent to providing DHM (if qualifies per hospital policy) or formula if MOM is not available. Infants are only eligible to receive donor milk only if 1) MOM is not available 2) if infant initiates feeds before day 3 of age. The donor milk feed would be stopped on day 5 of age. After day five of age, the infant will receive formula if MOM is not available. This is congruent with the current donor milk policy (see Policy #12785). It is highly unlikely given these infants would receive any donor milk because these infants require surgery and often are waiting return of bowel function . The median age of initiation of feeds is 12 days of age for infants with gastroschisis (PMID: 33647253) which exceeds the days of what the hospital policy says for eligibility which is initiates feed before day 3 of age. If the infant does not qualify for any donor milk and MOM is not available, the infant will receive formula Receives: Dietary Supplement: Standard of Care |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time to full feed
: In infants with congenital gastrointestinal pathologies (gastroschisis, giant omphalocele, atresia, midgut volvulus, Hirschsprung disease, CGP), to determine if use of an exclusive human milk diet will decrease the number of days to full feeding volume (120 ml/kg/day) (29 subjects per power calculation) compared to human milk/formula
Measured: From birth to 120 days or until discharge
Secondary outcomes (5)
Central line infection rate
To compare rate of central line infections in infants given exclusive human milk versus infants given standard care.
Measured: up to 120 days or discharge
Portion of parents own milk at time of discharge
: To compare proportion of parents providing any/exclusive mother's own milk (MOM) at discharge in infants given exclusive human milk arm versus standard care arm
Measured: Up to 120 days or discharge
Gut Microbiome Relative Abundance and Diversity
To examine if utilization of donor milk when mother's own milk is insufficient alters the infant's gut microbiome alpha diversity and beta diversity and bacterial relative abundances
Measured: Up to 120 days or discharge
Mother's milk microbiome relative abundance and diversity
To discern how mother's own milk microbiome differs from donor milk microbiome relative abundances and diversity. We will examine how the milk microbiomes influences the infant's gut microbiome and time to full feeds.
Measured: Up to 120 days or discharge
Concentrations of Antigen-specific immunoglobulins
To compare total and antigen-specific immunoglobulins in donor milk versus MOM
Measured: From birth to 120 days or discharge

Questions about this trial
What is this clinical trial studying?
A study testing Exclusive Human Milk in people with Gastrointestinal Complication and Intestinal Obstruction, run by Seattle Children's Hospital at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 30 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Leonel Arellano (915-443-4390, leonel.arellano@seattlechildrens.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time to full feed (time frame: From birth to 120 days or until discharge). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06072976, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2026.
