Study Population

Approximately 60 healthy breastfed infants aged ≥14 to ≤35 days at enrollment. To ensure balanced sex representation of the study population, approximately 30 males and 30 females will be enrolled in the study.

You may qualify if:

  • Written informed consent is obtained from parent(s)/ legally authorized representative(s) (LAR(s)).
  • Parent(s)/ LAR(s) must be able to provide evidence of parental authority and identity.
  • Parents/ LARs must understand the informed consent and other study documents.
  • Infants whose parent(s)/ LAR (s) has consented to blood collection as per protocol.
  • Able to temporarily store stool samples in a household freezer.
  • Infants whose parent(s)/LAR(s) are willing and able to comply with scheduled visits, and the requirements of the study protocol.
  • Infants whose parent(s)/LAR(s) can be contacted directly by telephone throughout the study.
  • Healthy term infant (≥37 weeks of gestation)
  • At enrollment visit, postnatal age ≥14 to ≤35 days (date of birth = day 0)
  • Birth weight is appropriate for gestational age (i.e., ≥ 2500g and ≤ 4500g)
  • Infant has exclusively received breastmilk from birth to enrollment, and parent intends to continue exclusive breastmilk feeding until infant age 6 months.

You may not qualify if:

  • 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).
  • Suspected or documented systemic or congenital infections (e.g., human immunodeficiency virus, cytomegalovirus, syphilis).
  • Presently receiving or have received prior to enrolment 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 microbiota and characteristics (e.g., oral, or systemic antibiotics, glycerin suppositories, bismuth-containing medications, docusate, Maltsupex, or lactulose); growth (e.g., insulin or growth hormone); gastric acid secretion.
  • Infants whose parent(s) has(ve) not reached legal age of majority (18 years old) upon enrollment.
  • Currently participating or having participated in any interventional clinical trials since birth.
