A Study of a Probiotic Food Supplement Containing B. Infantis (EVC001) in Healthy Breastfed Infants at Risk of Developing Atopic Dermatitis
Study Details
Study Description
Brief Summary
The purpose of this study is to assess the effect of B. infantis (EVC001) versus placebo supplementation, in healthy breastfed infants at risk of developing atopic dermatitis (AD), on cumulative incidence of physician-diagnosed AD during the first year of life.

Outcome Measures
Primary Outcome Measures
- Number of Participants with Atopic Dermatitis (AD) through Week 52 [Up to Week 52]
Number of participants with atopic dermatitis (AD) through Week 52 will be reported. AD will be diagnosed if three of the following four criteria are met: 1) pruritus, 2) typical morphology and distribution (facial and extensor involvement), 3) chronic or chronically relapsing dermatitis, 4) personal or family history of atopic disease.
Secondary Outcome Measures
- Percentage of Infants with Adverse Events Through Weeks 12, 52 and 104 [Up to Weeks 12, 52 and 104]
The percentage of infants with AEs, serious adverse events (SAEs), AEs leading to discontinuation, and AEs related to the gastrointestinal system will be determined at Weeks 12, 52 and 104.
- Number of Participants with Atopic Dermatitis (AD) Through Weeks 24 and 104 [Up to Weeks 24 and 104]
Number of participants with AD through Week 24 and 104 will be reported. AD will be diagnosed if three of the following four criteria are met: 1) pruritus, 2) typical morphology and distribution (facial and extensor involvement), 3) chronic or chronically relapsing dermatitis, 4) personal or family history of atopic disease.
- Time to Onset of AD Through Weeks 52 and 104 [Up to Weeks 52 and 104]
Time to onset of AD through Weeks 52 and 104 will be reported.
- Percentage of Infants with B. infantis Gut Colonization at Week 12 [Week 12]
Percentage of infants with B. infantis gut colonization at Week 12 will be reported.
- Atopic Dermatitis (AD) Severity Based on the Eczema Area and Severity Index (EASI) Score at Time of AD Onset and at Weeks 12, 52, and 104 [At the time of AD onset (up to Week 104), Weeks 12, 52, and 104]
Atopic Dermatitis (AD) severity based on the EASI score at time of AD onset and at Weeks 12, 52, and 104 will be reported. Physician rates severity of four parameters: erythema, infiltration, excoriation and lichenification on a scale of 0 (none) to 3 (severe) on 4 anatomic regions of the body: head, trunk, upper limbs, and lower limbs. Physician determines how much area is affected on a scale of 0 (none) to 6 (90 to 100%). A body region score is determined by multiplying the sum of the severity scores by the affected area score by a constant corresponding to the relative body surface area for that body region (20%, 30%, 20%, and 30%, respectively). The 4 body region scores are summed to yield the EASI score which ranges from 0 to 72, with a higher score indicating more severe AD. The AD onset in the study's population can be diagnosed throughout the study at either scheduled or unscheduled visits starting as early as 1 month of age.
- AD Severity Based on the Patient-Oriented Eczema Measure (POEM) Score at Time of AD Onset and at Weeks 12, 52, and 104 [At the time of AD onset (up to Week 104), Weeks 12, 52, and 104]
The POEM is a simple, valid, easily interpreted, and reproducible tool for assessing AD and monitoring aspects of the disease that are important to participants with AD. Study Personnel will interview Caregivers at time of AD diagnosis and (only for participants with AD) at Weeks 12, 52, and 104 to rate seven symptoms (itchy skin, sleep disturbance, bleeding skin, skin weeping/oozing, skin flaking, skin cracking, skin dryness/roughness) using a 5-point scale of frequency of occurrence during the previous week (no days, 1-2 days, 3-4 days, 5-6 days, every day). The total score is the sum of the 7 items which is ranged from 0 to 28; a high score is indicative of more severe AD. The AD onset in the study's population can be diagnosed throughout the study at either scheduled or unscheduled visits starting as early as 1 month of age.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Healthy term infant
-
Has at least one first degree relative (that is biological parent or full sibling) with a history of atopic disease (that is mother-reported, physician-diagnosed Atopic Dermatitis (AD), allergic rhinitis, or asthma)
-
Breastfeeding established (as determined by the principal Investigator [PI] or designee) at the time of study enrollment (Day 0), with maternal intent to maintain exclusive breastfeeding for greater than or equal to (>=)12 weeks
-
