Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 6 to 11 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Who may be able to join

  • Participant must be between >=6 to <12 years of age (inclusive), at the time of signing the informed consent
  • 15 kg <= body weight <60 kg.
  • Atopic dermatitis participants:
  • Male or female pediatric participants.
  • Participants with AD diagnosis according to Hanifin and Rajka criteria at least 1 year before screening.
  • Investigator Global Assessment (IGA) score of >=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.

Who cannot join

  • 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.
  • The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

About this study

Official title: Open-label Exploratory Study to Evaluate the Effect of Dupilumab on Skin Barrier Function in Pediatric Patients With Moderate to Severe Atopic Dermatitis

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.

Atopic Dermatitis ParticipantsExperimentalPediatric participants with moderate-to-severe atopic dermatitis (AD) and with baseline body weight more than or equal to (>=) 15 kilograms (kg) and less than (<) 30 kg received a subcutaneous (SC) loading dose of dupilumab 600 milligrams (mg) (2 injections of dupilumab 300 mg) on Day 1 (Week 0) followed by dupilumab 300 mg SC injection every 4 weeks (Q4W), from Week 4 to Week 12.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change From Baseline in Transepidermal Water Loss (TEWL) After 5 Skin Tape Stripping (STS) on Lesional Skin (LS) in AD Participants at Week 16

    TEWL assessment: a noninvasive in vivo measurement of water loss across stratum corneum that is used to characterize skin barrier function (SBF). TEWL combined with STS measures SBF. With STS, the uppermost layers of the skin are peeled away using adhesive discs. Lesional skin (LS) areas for TEWL assessment and STS was identified at Baseline ('predefined skin area'). Within the predefined LS areas, 3 closely adjacent non-overlapping spots were identified for subsequent SBF assessment. TEWL was measured prior to STS and after 5, 10, 15 and 20 STS on pre-defined LS areas at specified time points. STS assessment at Baseline (Week 0, Day 1) and Week 16 was conducted on the first spot. Percent Change from Baseline at Week 16 in TEWL after 5 STS on LS (first spot) in AD participants were reported in this outcome measure (OM).
