Clinical Trial Summary

This is a non-randomized, single-arm, open-label, prospective interventional study using a commercially available starter infant formula in healthy term formula-fed infants with a parallel group of healthy term breast-fed infants as reference group. Approximately 120 male and female infants (60 per group) who are 3-28 days old and are exclusively or predominately formula-feeding or breastfeeding will be enrolled.

Description:

Breastmilk contains an abundance of structurally diverse compounds having important physiologic roles. These include glycoproteins which are biologically active and involved in infant gut, immune and brain development (Jiang and Lönnerdal 2016).

The overall purpose of this study is to study the effectiveness of a term infant formula rich in glycoprotein (formula-fed group) on gastrointestinal tolerance, and gastrointestinal health in healthy term infants compared to a breast-fed reference group. We hypothesize that there will be comparable gastrointestinal tolerance in formula-fed and breast-fed and that fecal bifidobacteria changes in early infancy in the formula-fed group are similar to that of breast-fed infants.

Eligibility

Inclusion Criteria:

1. Evidence of personally signed and dated informed consent document indicating that the infant's parent(s)/ legally accepted representatives LAR have been informed of all pertinent aspects of the study.

2. Infants whose parent(s)/LAR have reached the legal age of majority in the countries where the study is conducted.

3. Infants whose parent(s)/LAR are willing and able to comply with scheduled visits, and the requirements of the study protocol.

4. Infants whose parent(s)/LAR can be contacted directly by telephone throughout the study.

5. Infants whose parent(s)/LAR have a working freezer.

6. Infants must meet all the following inclusion criteria to be eligible for enrolment into the study:

• Healthy term infant (37-42 weeks of gestation).

• At enrolment visit, post-natal age 3-28 days (date of birth = day 0)

• Birth weight = 2500g and = 4500g.

• Formula-fed infants only: Infants must predominantly consume and tolerate a standard cow's milk infant formula prior to enrolment and their parent(s)/LAR must have independently elected, before enrolment, not to exclusively breastfeed. Predominantly formula feeding means that the infant's predominant source of nourishment has been formula. Specifically, infants are fed with formula for at least 75% of total milk feeds per day.

• Breastfed infants only: Infants must have been predominantly breastfed since birth, and their parent(s)/LAR must have made the decision to continue predominant breastfeeding for the duration of the study. Predominant breastfeeding allows infants to be mix fed with breastmilk and other milks. It means that the infant's predominant source of nourishment has been breastmilk. Specifically, infants are fed with breast milk for at least 75% of total milk feeds per day.

Exclusion Criteria:

1. Infants with conditions requiring infant feedings other than those specified in the protocol.

2. Infants receiving complementary foods or liquids defined as 4 or more teaspoons per day or approximately 20 g per day of complementary foods or liquids at or prior to enrollment.

3. Infants who have a medical condition or history that could increase the risk associated with study participation or interfere with the interpretation of study results, including:

• Evidence of major congenital malformations (e.g., cleft palate, extremity malformation).

• Documented systemic or congenital infections (e.g., human immunodeficiency virus, cytomegalovirus, syphilis).

• Previous or ongoing severe medical or laboratory abnormality (acute or chronic) which, in the judgment of the investigator, would make the infant inappropriate for entry into the study.

4. Infants who are presently receiving or have received prior to enrollment probiotic supplements or any of the following: medication(s) or supplement(s) which are known or suspected to affect the following: fat digestion, absorption, and/or metabolism (e.g., pancreatic enzymes); stool characteristics and microbiota (e.g., oral and systemic antibiotics, glycerin suppositories, bismuth-containing medications, docusate, Maltsupex, or lactulose); growth (e.g. insulin or growth hormone); gastric acid secretion.

5. Currently participating or having participated in another clinical trial since birth.

6. Subjects or subjects' parent(s) or legal representative who are not willing and not able to comply with scheduled visits and the requirements of the study protocol.

Intervention

Dietary Supplement:
• Commercially Available Starter Infant Formula
Study formula is provided in powder form and will be administered orally, ad libitum, via an infant feeding bottle and the volume of formula offered to the infant will be guided by the recommended feeding table for the age group or by physician recommendation. The amount consumed by the infant will vary by each infant's weight and appetite.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall gastrointestinal (GI) tolerance	Compare the overall gastrointestinal (GI) tolerance between the formula-fed and the breast-fed infants from enrolment to 6 weeks of intervention.; Assessed through the IGSQ-13 (Infant Gastrointestinal Symptoms Questionnaire). The IGSQ-13, consisting of 13 questions, is a retrospective, standardized, validated, questionnaire of GI symptoms and related behaviors that the infant experienced over the past week from a parent's perspective. Overall GI tolerance is assessed from the IGSQ index score, computed from the 13 questions. Possible scores range from 13 - 65, with lower scores representing lower overall GI burden.	Day 39-45
Secondary	Change in Bifidobacteria abundance	Change in Bifidobacteria abundance from baseline to be measured in the stool samples collected.	Day 1, Day 36-44
Secondary	Fecal microbiota	Overall fecal microbiota composition and diversity and community type. Diversity will include relative abundance of beneficial and pathogenic bacteria species (such as beneficial bifidobacteria diversity). To be measured in stool samples collected.	Day 1, Day 36-44
Secondary	Fecal metabolism	To be measured in stool samples collected. The metabolic profile consist of pH and organic acids (such as but not restricted to acetate, lactate, butyrate, and propionate), analyzed using HPLC.	Day 1, Day 36-44
