Growth of Infants Clinical Trial
Official title:
Effects of Addition to Infant Formula of 2-fucosyllactose (2-FL) on Growth, Fecal Bacterial Populations and Safety
OBJECTIVES: Primary: The primary objective is to determine whether the mean weight gain over a 16-week interval starting on or before 14 days of life differs between infants fed one of two infant formulas as their sole source of nutrition: a commercial formula using a canola l fat blend (Control, E23) or the same formula containing the human milk oligosaccharide (Test (HMO) 2-fucosyllactose (2FL). Mean weight gain also will be compared to that of a concurrently enrolled reference group of exclusively breastfed infants.
METHODOLOGY/ STUDY DESIGN: This study is double blinded-randomized controlled trial with two arms and a reference breast fed group. The experimental variable is the composition of infant formula fed to healthy term infants for a period of 16 weeks upon entering the study as their sole source of nutrition. The formulations are a commercial control (Control, NPS-E23); and the control formula containing the human milk oligosaccharide (HMO) 2-fucosyllactose (2FL) at 1g/L (HMO, NPS-E23XA). Infants will be enrolled on or before 14 days of age and fed a study assigned formula for 16 weeks. Weight, length and head circumference will be measured at baseline and 2, 4, 6, 8, 12 and 16 weeks of study entry. Formula volume will be recorded for a three-day period before each visit. Fecal samples will be obtained at baseline (convenience samples) and at week 16 for all subjects and analyzed for microbial populations. Buccal cheek cells of all infants, and mothers of breast fed infants, obtained by swab at week 16 will be genotyped for FUT2. Information on adverse events and new/change of medications will be collected at in person visits and by telephone interviews between in-person visits. NUMBER OF SUBJECTS: It is estimated that approximately up to approximately 200 subjects will be enrolled in the formula groups to obtain up to approximately 65 evaluable per protocol subjects in each group. As non-randomized reference group of approximately 85 breastfed infants will be enrolled to obtain approximately 65 evaluable infants. ;
