Efficacy and Safety of Subcutaneous Dupilumab in Participants With Asthma/Asthmatic Wheeze Aged 2 to <6 Years (LIBERTY ASTHMA TREKIDS)
Study Overview
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).
Study details
The duration per participant is up to 120 Weeks.

- 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 dupilumab or any other 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).
