Study summary

This is a parallel, Phase 3, 2-arm study to evaluate the efficacy and long-term safety of dupilumab treatment in children 2 to \<6 years of age with uncontrolled asthma and/or recurrent severe asthmatic wheeze. The study will be conducted in 2 parts. Part A will be a 52-week, randomized, double-blind, placebo-controlled study to assess the safety and efficacy of dupilumab in children aged 2 to \<6 years old with uncontrolled asthma and/or recurrent severe asthmatic wheeze. At the end of Part A, all eligible participants will be offered participation in Part B, an optional open-label extension phase.

Study details include:

Part A:

The study duration of part A will be up to 68 weeks consisting of a 4-week Screening, a 52week treatment period, and a 12-week post-treatment follow-up period. For participants who will chose to participate in Part B, the study duration will be up to 120 weeks (additional 52-week treatment period).

Part B:

For participants who will choose to participate in Part B, the study duration will be up to 120 weeks (Part A [4-week Screening and a 52-week treatment period] plus additional 52-week treatment period and a 12-week post-treatment follow-up period).

Read the detailed description

The duration per participant is up to 120 Weeks.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participant must be 2 to \<6 years of age
  • Diagnosis of asthma or recurrent severe asthmatic wheeze that is not controlled with chronic ICS for at least 3 months with stable use of at least low dose ICS for ≥1 month prior to Screening Visit 1 with evidence of uncontrolled asthma and/or recurrent severe asthmatic wheeze.
  • At least one additional major criterion from the modified asthma predictive index:

    1. Physician diagnosed Atopic Dermatitis,
    2. Allergic sensitization to at least 1 aeroallergen (with a positive serum IgE defined as a value ≥0.35 kU/L).

      OR 2 minor criteria:

    3. Wheezing unrelated to colds,
    4. Peripheral blood eosinophilia ≥4%,
    5. Allergic sensitization to milk, eggs, or peanuts (defined by serum specific IgE >0.35 kU/L.
  • Parent(s)/caregiver(s)/legal guardian(s) willing and able to comply with clinic visits and study-related procedures.
  • Parent(s)/caregiver(s)/legal guardian(s) able to understand the study requirements.
  • Participants/parent(s)/caregiver(s)/legal guardian(s), as appropriate, must be able to understand and complete study-related questionnaires
  • Body weight at screening and randomization >5 kg and \<30 kg.
  • Parents or caregivers or legal guardian capable of giving signed .

Exclusion criteria

Exclusion Criteria:

Participants are excluded from the study if any of the following criteria apply:

  • Severe asthma with the need for chronic oral/systemic use (>1 month continuous) at the time of screening enrollment.
  • History of a systemic reaction or anaphylaxis to biologic therapy, including any .
  • History of prematurity (\<34 weeks gestation).
  • Any other chronic lung disease that would impair lung function (eg, cystic fibrosis, bronchopulmonary dysplasia) or chronic lung disease of prematurity or need for oxygen for more than 5 days in the neonatal period.
  • History of life-threatening asthma (eg, requiring intubation).

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 13, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
