About this trial

The AdVEMPrem study is exploring whether tiny particles called extracellular vesicles (EVs), which are naturally found in human milk, can help protect very premature babies from serious gut problems such as necrotizing enterocolitis (NEC). NEC is a dangerous condition that affects the intestines of preterm infants and can lead to long-term health issues.

Human milk is the best nutrition for babies, but when a mother's own milk is not available, donor human milk (DHM) is used. EVs in milk carry proteins, fats, and genetic material that may support gut development, immunity, and brain growth. While laboratory studies suggest EVs are beneficial, their effects in premature babies have not yet been proven.

In this study, 20 very preterm infants (\<32 weeks of gestation) will be enrolled during their stay in the Neonatal Intensive Care Unit (NICU). All babies in the study will receive oral supplementation with EVs isolated from donor human milk. Researchers will monitor feeding tolerance, growth, intestinal health, and early development. Blood and urine samples will also be collected to study how EVs affect metabolism and stress markers.

The main goal is to see if EV supplementation is safe and well tolerated. Longer-term follow-up will explore whether EVs improve growth and neurodevelopment as the babies grow. This research could lead to new nutritional strategies to reduce NEC and improve outcomes for premature infants and their families.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Preterm infants born at <32 weeks gestational age

Age between 0 and 14 days of life at enrollment

At risk of developing necrotizing enterocolitis (NEC)

Written informed consent obtained from parent(s) or legal guardian(s)

Disqualifiers

Major congenital anomalies or chromosomal abnormalities

Severe gastrointestinal malformations (e.g., gastroschisis, intestinal atresia)

Conditions incompatible with enteral feeding or EV supplementation

Participation in another interventional clinical trial

Trial population

Preterm infants at risk of developing necrotizing enterocolitis (NEC), recruited between 14 and 28 days of life during their stay in the Neonatal Intensive Care Unit (NICU). A total of 20 infants will be enrolled to receive oral administration of extracellular vesicles (EVs) isolated from donor human milk (DHM) as a dietary supplement.

Trial outcomes

Primary outcomes

1

Number of participants with treatment-related serious adverse events

Safety will be evaluated by the number of participants experiencing one or more treatment-related serious adverse events, defined as any of the following: (i) necrotizing enterocolitis (Bell stage ≥ II); (ii) metabolic or renal complications requiring medical intervention, (iii) cholestasis, or (iv) culture-proven sepsis. Participants experiencing multiple events will be counted once.

Time frame
From enrollment until term-equivalent age (i.e., up to 40 weeks postmenstrual age)
2

Tolerance of donor human milk EV supplementation

Feeding tolerance is evaluated by the number of participants without clinical signs of gastrointestinal symptoms and successful progression of enteral feeding.

Time frame
From enrollment until term-equivalent age (i.e., up to 40 weeks postmenstrual age)

Secondary outcomes

1

Infant weight

Measurements of weight (grams)

Time frame
From enrollment until term-equivalent age (weekly) and at 3, 6, 12, 18, and 24 months of corrected age
2

Infant length
