This study is a multicenter, double-blind, randomized, controlled, parallel-designed, prospective study and is intended to evaluate the nutritional adequacy and tolerance of a new study formula compared with a concurrent control formula. Approximately 450 infants will be enrolled from approximately 3 China sites. Of these infants, approximately 300 will be randomized 1:1 to receive an investigational formula or a control formula for 16weeks of feeding. The remaining approximately 150 infants will be enrolled as a breastfeeding reference group. The primary outcome measure is the rate of weight gain in g/day between baseline and 16 weeks in the test group compared to control formula group. Participants will have the option of providing stool samples at 8 weeks and 16 weeks for analysis of microbiota and metabolomics. The study period will be 16 weeks, and all infants in the 2 formula groups will receive formula free of charge for 6 months.
Primary Objective
1) Compare the rate of weight gain (in g/day) between infants receiving an investigational formula and infants receiving a control formula between at baseline (B), B+2 weeks, B+4 weeks, B+8 weeks, B+12 weeks, and B+16 weeks.
