Efficacy and Safety of Subcutaneous Dupilumab in Participants With Asthma/Asthmatic Wheeze Aged 2 to <6 Years (LIBERTY ASTHMA TREKIDS)

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).

Eligibility

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 informed consent.

Exclusion Criteria:

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

* Severe asthma with the need for chronic oral/systemic corticosteroid use (\>1 month continuous) at the time of screening enrollment.
* History of a systemic hypersensitivity reaction or anaphylaxis to biologic therapy, including any excipient.
* 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).
