NCT05680298

Brief Summary

This is a 32-week, open-label, exploratory study with a 4-week screening period, 16-week treatment phase designed to investigate dupilumab's effect on skin barrier function as measured by TEWL before and after STS in approximately 20 pediatric patients with moderate-to-severe AD (not more than 24 patients aged ≥6 and \<12 years old), and a 12-week follow-up period. Patients will have 1 on-site visit/week, up to Week 4, 1 on-site visit every 2 weeks from Week 4 to Week 8, and 1 on-site visit every 4 weeks from Week 8 to Week 16 End of Treatment (EoT) phase visit, and every 6-weeks thereafter during the follow-up period and by this will end the study for each participant (End of Study \[EoS\]). The maximum duration of the study per participant will be 32 weeks (including screening period). Skin barrier function in approximately 10 healthy volunteers (not more than 20 healthy participants aged ≥6 and \<12 years old) matched for age (match on age ±2 years), gender, location of targeted lesion area, and study site to the AD cases will be assessed in a similar manner at baseline, and will have 1 on-site visit/week, up to Week 4, 1 on-site visit every 2 weeks from Week 4 to Week 8, and 1 on-site visit every 4 weeks from Week 8 to Week 16 EoT phase visit, and every 6-weeks thereafter during the follow-up period, serving as a reference comparator for skin barrier function.

Outcome Measures

Primary Outcomes (1)

  • Percent change from baseline in TEWL after 5 STS assessed on lesional skin at Week 16 in AD patients.

    From baseline to week16

Secondary Outcomes (1)

  • Change from baseline in TEWL before and after 10, 15, 20 STS assessed on lesional skin in AD patients at Week 16.

    From baseline to week16

Study Arms (2)

AD patients

EXPERIMENTAL

Pediatric patients (≥6 and \<12 years of age) with moderate-to-severe AD will receive a SC injection of dupilumab depending on the body weight

Drug: Dupilumab

Healthy volunteers

NO INTERVENTION

Except for IMPs administration, skin barrier function assessments for healthy volunteers are conducted at the same time and in the same measurement conditions as for AD patients.

Interventions

solution for injection, Subcutaneous injection

Also known as: Dupixent
AD patients

Eligibility Criteria

Age6 Years - 12 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Participant must be between ≥6 to \<12 years of age inclusive, at the time of signing the informed consent.
  • Male or female.
  • Patients with AD diagnosis according to Hanifin and Rajka criteria at least 1 year before screening.
  • Investigator Global Assessment score of ≥3 (for US patients) or IGA ≥4 (for EU patients) at screening (on the 0 to 4 scale) depending on approved label indication in the country.
  • Patients with moderate-to-severe AD are eligible to be treated with dupilumab according to product label.
  • Patients with AD must have 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 to 3 scale of the ISS.
  • Participants should have a non-lesional (normal looking) skin area 4 cm from the edge of the lesional area. If unable to identify non-lesional skin 4 cm from the lesional area, it is acceptable to identify normal looking skin as close to the lesion as possible.
  • Willing to refrain from applying any topical medications on the target assessment areas (including lesional and non-lesional) throughout the study until EoS unless necessary to alleviate intolerable symptoms.
  • Willing to refrain from showers or soak in a bathtub with soaps and body washes within 6 hours before TEWL assessments.
  • Willing to NOT apply any moisturizers to the areas of the skin that are targeted assessment areas (lesional and non-lesional) during the entire study from Day -7 to Week 28 (EoS).
  • Willing and able to comply with all clinic visits and study-related procedures.
  • kg ≤ body weight \<60 kg
  • Age and gender matched (match on age ±2 years) to a selected AD patient by study site.
  • No current dermatologic or systemic condition that could interfere with the assessments.
  • kg ≤ body weight \<60 kg
  • +1 more criteria

You may not qualify if:

  • Medical conditions
  • 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 (ie, skin atrophy, ichthyosis, tinea infection, contact dermatitis).
  • Cracked, crusted, oozing, or bleeding AD lesions in the designated lesional assessment area leaving insufficient skin that is 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.
  • Systemic AD treatment, cyclosporine A (CsA), systemic corticosteroids, azathioprine (AZA), methotrexate (MTX), mycophenolate mofetil (MMF), or Janus kinase (JAK) inhibitors or phototherapy within 4 weeks of baseline.
  • Topical AD treatment within 1 week of baseline. Face and neck may be treated with topical steroids during the washout period if approved by the Investigator.
  • Severe concomitant illness(es) that, in the Investigator's judgment, would adversely affect the patient's participation in the study.
  • History of hypersensitivity reaction to tape or adhesives used in desquamme discs.
  • Patients administered live attenuated vaccines within the 4 weeks prior to the baseline visit or need to receive live (attenuated) vaccinations through Week 28.
  • Prior/concomitant therapy
  • Treatment with an investigational medication within 16 weeks or within 5 half-lives (if known) prior to Day 1, whichever is longer.
  • Patients who received a live vaccine within 4 weeks of baseline.
  • Prior/concurrent clinical study experience
  • +5 more criteria
