Is this trial a fit for you?

Likely a good fit

Ideal candidates are preterm infants born between 26 and 30 weeks gestation who are admitted to the NICU.

Probably not a fit

Patients with major congenital anomalies or those requiring extensive medical support prior to treatment may not benefit from this study.

What this trial studies

This pilot trial investigates the safety and tolerability of fecal filtrate transfers (FFT) from healthy term infants to preterm infants born between 26 and 30 weeks gestation. The study will recruit 20 donor infants and their mothers, collecting fecal samples over three years to assess microbiota development and safety. Preterm infants will be block randomized to receive either FFT or a saline placebo shortly after birth. The ultimate goal is to develop a treatment to prevent necrotizing enterocolitis, a severe gut disease affecting preterm infants.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of necrotizing enterocolitis in preterm infants.

How similar studies have gone: While the use of bacteriophages is a novel approach in this context, similar studies have shown promise in other areas of microbiome-related treatments.
