Assessment of the Safety and Efficacy of Dupilumab in Children With Asthma (Liberty Asthma Excursion)

November 10, 2025 updated by: Sanofi

One Year Study to Evaluate the Long-term Safety and Tolerability of Dupilumab in Pediatric Patients With Asthma Who Participated in a Previous Dupilumab Asthma Clinical Study

Primary Objective:

  • To evaluate the long-term safety and tolerability of dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study.
  • To evaluate the efficacy of dupilumab in children of 6 to <12 years of age with uncontrolled persistent asthma in the Japan sub-study.

Secondary Objectives:

  • To evaluate the long-term efficacy of dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study.
  • To evaluate dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study with regard to:

    • Systemic exposure.
    • Anti-drug antibodies (ADAs).
    • Biomarkers.
  • To evaluate the safety and tolerability of dupilumab in pediatric patients with asthma in the Japan sub-study
  • To evaluate dupilumab in pediatric patients with asthma in the Japan substudy with regard to:

    • Systemic exposure,
    • Anti-drug antibodies (ADAs),
    • Biomarkers

Description

Inclusion criteria :

  • Pediatric patients with asthma who completed the treatment in a dupilumab asthma trial (EFC14153).
  • Signed written informed consent/assent. Specific for Brazil: EFC14153 patients from Brazil, who prematurely discontinued Investigational Medicinal Product (IMP) to receive Yellow Fever vaccine (a live attenuated vaccine) during Yellow Fever outbreak, are allowed to be enrolled in LTS14424 after completing the required procedures in EFC14153 (completion of remaining visits and procedures until end of treatment (EOT) V28, considered as V1 for LTS14424).

Patients who are not able to complete their treatment in Study EFC14153 due to the COVID-19 pandemic will be allowed to enroll into Study LTS14424. Patients who enroll in LTS14424 after completing the EFC14153 EOS visit should have eligibility for LTS14424 reevaluated including background medication check and laboratory assessments (including complete blood count [CBC] with differential and basic chemistry) within 1 month prior to LTS14424 Visit 1.

For Japan sub-study

  • Signed written inform consent/assent
  • Children 6 to <12 years of age, with a physician diagnosis of persistent asthma for ≥12 months prior to screening
  • Blood eosinophil count ≥150 cells/μL or fractional exhaled nitric oxide (FeNO) ≥20 parts per billion (ppb) at screening visit (Visit 0).

Exclusion criteria:

  • Any chronic lung disease other than asthma (eg, cystic fibrosis, bronchopulmonary dysplasia) which may impair lung function.
  • Inability to follow the procedures of the study/noncompliance (eg, due to language problems or psychological disorders).
  • Patients receiving concomitant treatment or required a new concomitant treatment prohibited in the study.
  • Patients or his/her parent(s)/caregiver(s)/legal guardian(s) is related to the Investigator or any Sub-Investigator, research assistant, pharmacist, study coordinator, other staff thereof directly involved in the conduct of the study.
  • Patients who experienced any hypersensitivity reactions to dupilumab in a previous dupilumab study, which, in the opinion of the Investigator, could indicate that continued treatment with dupilumab may present an unreasonable risk for the patient.
  • Any abnormalities or adverse events at screening (last treatment visit in the study EFC14153 will be the screening visit) that per Investigator judgment would adversely affect patient's participation in this study or would require permanent IMP discontinuation.
  • For female patients who have commenced menstruating at any time during the study and are either:
  • Found to have a positive urine pregnancy test, or
  • Sexually active, not using an established acceptable contraceptive method.
  • Planned live, attenuated vaccinations during the study.
  • Patients with active autoimmune disease or patients using immunosuppressive therapy for autoimmune disease (eg, juvenile idiopathic arthritis, inflammatory bowel disease, systemic lupus erythematosus) at enrollment.

For Japan sub-study:

  • Any chronic lung disease other than asthma (eg, cystic fibrosis, bronchopulmonary dysplasia) which may impair lung function.
  • Inability to follow the procedures of the study/noncompliance (eg, due to language problems or psychological disorders).
  • Patients receiving concomitant treatment or required a new concomitant treatment prohibited in the study at the screening and enrollment visits.
  • Patients who previously have been treated with dupilumab
  • Diagnosed with active parasitic infection (helminthes); suspected or high risk of parasitic infection, unless clinical and (if necessary) laboratory assessments have ruled out active infection before randomization
  • Known or suspected history of immunosuppression, including history of invasive opportunistic infections (eg, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis), despite infection resolution; or unusually frequent, recurrent, or prolonged infections, per Investigator's judgment.

Main Study: Percent Change From Baseline in Blood Eosinophil Count at Week 64
Time Frame: Baseline (Day 1) to Week 64
Blood samples were collected at specified timepoints to assess percent change from baseline in eosinophil count. Baseline was defined as the original baseline of parent study EFC14153.
Baseline (Day 1) to Week 64
Percent Change From Baseline in Total Immunoglobulin (Ig) E in Serum at Week 64
Time Frame: Baseline (Day 1) to Week 64
Blood samples were collected at specified timepoints to assess percent change from baseline in total IgE in serum. Baseline (main study): the original baseline of parent study EFC14153. Baseline (sub-study): last available measurement prior to first study treatment dose if participant was treated, or last available value up to enrollment if participant was not exposed to study treatment in current study.
Baseline (Day 1) to Week 64
Japan Sub-study: Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) at Week 64
Time Frame: Baseline (Day 1) to Week 64
FeNO was analyzed using a NIOX instrument or similar analyzer using a flow rate of 50 milliliter per second. FeNO assessment was conducted prior to spirometry and following a fast of ≥1 hour. Baseline was defined as the last available measurement prior to first study treatment dose if participant was treated, or last available value up to enrollment if participant was not exposed to study treatment in the current study.
