Lacto-N-tetraose (LNT) is a human milk oligosaccharide (HMO) present in human colostrum and milk. HMOs are largely undigestable and have no direct nutritive benefit to the infant, but act as a prebiotic substrate for beneficial bacteria (bifidobacteria, in particular) in the infant gut. Exclusively formula-fed infants lack HMOs in their diet in the absence of naturally occurring HMOs from breast milk. The proposed clinical study will evaluate the ability of a prebiotic supplement (LNT) to initiate intestinal colonization of a probiotic strain (B. infantis EVC001) in exclusively formula-fed infants. B. infantis EVC001 has been shown to be well-tolerated and safely consumed in breastfed infants. This study also aims to evaluate the safety and tolerability of LNT in different doses when consumed daily with B. infantis EVC001.

Primary | B. infantis levels in infant stool | To evaluate the ability of different doses of a prebiotic supplement (LNT) to initiate intestinal colonization of a probiotic strain (B. infantis EVC001) in exclusively formula-fed infants. DNA will be extracted from stool swab samples and will be used for quantitative PCR to determine levels of B. infantis. | Baseline, Days 1-35, Day 40 | |
Secondary | Total infant gut microbiome modulation | To evaluate the total gut microbiome modulation from supplementation of B. infantis with and without a prebiotic supplement (LNT) in exclusively formula-fed infants. DNA and RNA will be extracted from stool swab samples and will be used for next generation sequencing to determine relative abundance of the most abundant bacterial taxa. | Baseline, Days 5, 12, 19, 26, 40 | |
Secondary | Frequency of adverse events | Frequency of treatment emergent adverse events (TEAEs), serious TEAEs and TEAEs causing premature discontinuation will be provided by treatment group. | During supplementation (Day 1 to Day 28) and Post-supplementation (Day 29 to Day 42) | |
Secondary | Frequency of gastrointestinal symptoms warranting a doctor's visit | Frequency of gastrointestinal symptoms warranting a doctor's visit will be provided by treatment group. | During supplementation (Day 1 to Day 28) and Post-supplementation (Day 29 to Day 42) | |
Secondary | Frequency of adverse events resulting in withholding or discontinuing the study products | Frequency of adverse events resulting in withholding or discontinuing the study products will be provided by treatment group. | During supplementation (Day 1 to Day 28) |
