Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if supplementing healthy term infants delivered vaginally who consume breast milk, formula, or both with a probiotic for 21 consecutive days increases levels of bacteria in infants' stool.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of phase 1 of this two phase clinical trial is to determine: 1) the effect of decreasing levels of human milk oligosaccharides on fecal B.infantis during and after 21 days of supplementation with Evolve activated B.infantis using exclusively breastfed, mixed-fed and exclusively formula-fed infants; 2) determine the effect of Evolve activated B.infantis on fecal B.infantis levels in exclusively breastfed infants compared to pre-supplementation levels.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

The feeding patterns of eighty eligible infants (8 to 12 weeks in age) will be characterized based on a 7-day diet record that will be filled out by their mothers during the 7-day lead-in period starting with Day -7 and ending with Day -1. Of the eighty infants, twenty will be exclusive breast feeders (BF), twenty will be exclusive formula feeders (FF) and forty will be mixed-feeders (MF). Infants in all three feeding groups will consume B. infantis for twenty-one consecutive days. Participants will then enter the observational phase until their infant turns 1 year old.

Study Groups

Exclusively breastfed

Exclusive breastfeeding will be defined at screening as infants who have not consumed any infant formula after 7 days postnatal and have been exclusively breastfed without formula between day 7 of life through the end on the Lead-in period. ).
