About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Multi-center, Parallel-group Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Dupilumab Compared to Placebo in Japanese Patients With Atopic Dermatitis Aged 6 Months to <18 Years Whose Disease is Not Adequately Controlled With Existing Therapies

Primary Objective:

To evaluate the efficacy of dupilumab administered concomitantly with topical corticosteroids (TCS)

Secondary Objective:

To evaluate the efficacy of dupilumab administered concomitantly with TCS. To assess the safety of dupilumab over 16 weeks of treatment when administered concomitantly with TCS in participants.

To assess immunogenicity as determined by the incidence, titer, and clinical impact of treatment-emergent anti-drug antibodies (ADA) to dupilumab over time in pediatric patients with atopic dermatitis (AD) (aged ≥6 months to <18 years old) To assess the concentration of dupilumab in serum following administration concomitantly with TCS.

What is being measured

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

  1. Proportion of participants with Eczema Area and Severity Index (EASI)-75 (≥75% improvement from baseline EASI)

    The EASI is a composite index with scores ranging from 0 to 72.Higher scores indicates worse condition

    Measured: At Week 16

Secondary outcomes (20)
  1. Percent change in EASI score

    The EASI is a composite index with scores ranging from 0 to 72.Higher scores indicates worse condition

    Measured: From baseline to week 16

  2. Percent change in weekly average of daily worst itch numerical rating scale (NRS) for participants aged ≥6 years to <12 years old

    The worst itch NRS is a simple assessment tool those participants ≥6 years old to <12 years old will use to report the intensity of their pruritus (itch). This is an 11-point scale (0 to 10) in which 0 indicates no itching while 10 indicate worst itching possible.

    Measured: From baseline to week 16

  3. Proportion of participants with Investigator's Global Assessment (IGA) 0 or 1

    The IGA is an assessment instrument used in clinical studies to rate the severity of AD globally, based on a 5-point scale ranging from 0 (clear) to 4 (severe)

    Measured: At Week 16

  4. Percent change in weekly average of daily worst peak pruritus NRS for participants aged ≥12 years to <18 years old

    The peak pruritus NRS is a simple assessment tool that participants ≥ 12 to <18 years old will use to report the intensity of their pruritus (itch) ranges from 0 to 10 with 0 being 'no itch' and 10 being the' worst itch imaginable'

    Measured: From baseline to week 16

  5. Percent change in weekly average of daily worst scratch/itch NRS for participants aged ≥6 months to <6 years old

    The worst scratch/itch NRS is a simple assessment tool those participants ≥6 years old to <6 years old range from 1 to 10 in which 0 indicates no itching while 10 indicate worst itching possible

    Measured: From baseline to week 16

  6. Percent change for intensity of pruritus

    The intensity is assessed by numerical rating scale ranging from 0 to 10 which higher scale indicate worse itch condition

    Measured: From baseline to week 16

  7. Proportion of participants with EASI-50 (≥50% improvement from baseline)

    The EASI is a composite index with scores ranging from 0 to 72.Higher scores is worse condition

    Measured: At Week 16

  8. Proportion of participants with EASI-90 (≥90% improvement from baseline)

    The EASI is a composite index with scores ranging from 0 to 72.Higher scores is worse condition

    Measured: At Week 16

  9. Change in percent body surface area (BSA) affected by atopic dermatitis (AD)

    BSA affected by atopic dermatitis will be assessed for each major section of the body (head, trunk, arms, and legs).

    Measured: From baseline to week 16

  10. Change in Children's Dermatology Life Quality Index (CDLQI) (≥4 years)

    The CDLQI is a validated questionnaire designed to measure the impact of skin disease on the Quality of Life. The higher the score, the greater the impact is on the quality of life

    Measured: From baseline to week 16

  11. Change in Infants' Dermatitis Quality of Life Index (IDQOL) (<4 years)

    The IDQOL is a validated questionnaire developed to measure the impact of skin disease on the QOL of infants and preschool children <4 years of age wil completed by the child's parent or caregiver. The higher the score, the greater the impact is on the quality of life. -

    Measured: From baseline to week 16

  12. Change in Patient Oriented Eczema Measure (POEM)

    The POEM is a 7-item (dryness, itching, flaking, cracking, sleep loss, bleeding, and weeping) questionnaire used to assess disease symptoms with a scoring system of 1 to 28. The higher score, the higher morbidity

    Measured: From baseline to week 16

  13. Change in weekly average of daily worst peak pruritus NRS for participants aged ≥12 years to <18 years old

    The peak pruritus NRS is a simple assessment tool that participants ≥ 12 to <18 years old will use to report the intensity of their pruritus (itch) ranges from 0 to 10 with 1 being 'no itch' and 10 being the' worst itch imaginable'

    Measured: From baseline to week 16

  14. Change in weekly average of daily worst itch NRS for participants aged ≥6 years to <12 years old

    Measured: From baseline to week 16

  16. Number of Participants With Treatment-emergent Adverse Events (TEAEs), Treatment-emergent Serious Adverse Events (TESAEs), Serious Adverse Events (SAEs), and Adverse Event of Special Interest (AESI) From Baseline to 16 Weeks of Treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dupilumab SAR231893 in people with Atopic Dermatitis, run by Sanofi at 19 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of participants with Eczema Area and Severity Index (EASI)-75 (≥75% improvement from baseline EASI) (time frame: At Week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2025.
