Summary
Primary Objective:
- Evaluate changes in skin barrier function with transepidermal water loss (TEWL) assessed after skin tape stripping (STS) in predefined lesional skin in pediatric participants with moderate to severe atopic dermatitis (AD) treated with dupilumab.
Secondary Objectives:
* Evaluate changes in skin barrier function with TEWL assessed after STS in predefined lesional and non-lesional skin in pediatric participants with moderate to severe AD treated with dupilumab in reference to normal skin of healthy volunteers.
* Evaluate time course of change in skin barrier function with TEWL assessed before and after STS in predefined lesional and non-lesional skin in pediatric participants with moderate to severe AD during dupilumab treatment phase and follow-up period in reference to normal skin of healthy volunteers.
Eligibility Criteria
Inclusion criteria
- Participant must be between >=6 to =3 (for US participants) or IGA >=4 (for EU participants) at screening (on the 0-4 scale) depending on approved label indication in the country.
- Participants with moderate to severe AD those were eligible to be treated with dupilumab according to product label.
- Participants with AD must have had active lesions on the upper limbs or lower limbs (including trunk, if needed), with severity for lesion erythema or edema/papulation >=2 at screening on the 0-3 scale of the Individual Signs Score.
- Participants should have had a non-lesional (normal looking) skin area 4 centimeter (cm) from the edge of the lesional area. If unable to identify non-lesional skin 4 cm from the lesional area, it was acceptable to identify normal looking skin as close to the lesion as possible.
Healthy volunteers:
- Age and gender matched (match on age ±2 years) to a selected AD participant by study site.
Exclusion criteria
- Previous treatment with dupilumab within 6 months prior to screening.
- Skin conditions other than AD that can confound assessments in the area of TEWL assessments in the opinion of the Investigator (i.e., skin atrophy, ichthyosis, tinea infection, contact dermatitis).
- Cracked, crusted, oozing, or bleeding AD lesions in the designated lesional assessment area leaving insufficient skin that was adequate for TEWL assessments.
- Hypersensitivity to the active substance or to any of the excipients of dupilumab.
- Ocular disorder that in the opinion of the Investigator could adversely affect the individual's risk for study participation. Examples include -but are not limited to- individuals with a history of active cases of herpes keratitis; Sjogren's syndrome, keratoconjunctivitis sicca, or individuals with ocular conditions that require the use of ocular corticosteroids or cyclosporine.
- Healthy volunteers with a personal history of an atopic condition.
