Conditions
Outcome Measures
Primary Outcomes (6)
Change From Baseline in Eosinophils Cells Count in the Bronchial Submucosa at Week 12
Inflammatory cells i.e. eosinophils were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.
Baseline, Week 12
Change From Baseline in Mucin-Stained Area in the Bronchial Submucosa at Week 12
Mucin was identified by staining with Alcian-blue periodic acid-Schiff and/or immunostaining for MUC5AC and then the mucin-positive area was measured and expressed per square millimeter.
Baseline, Week 12
Change From Baseline in Mast Cells Count (Chymase Positive) in the Bronchial Submucosa at Week 12
Inflammatory cells i.e. mast cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.
Baseline, Week 12
Change From Baseline in Mast Cells Count (Tryptase Positive) in the Bronchial Submucosa at Week 12
Inflammatory cells i.e. mast cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.
Baseline, Week 12
Change From Baseline in T-Lymphocytes Count in the Bronchial Submucosa at Week 12
T-Lymphocytes i.e. CD3 positive cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.
Baseline, Week 12
Change From Baseline in T-Helper Lymphocytes Count in the Bronchial Submucosa at Week 12
T-helper i.e. CD4 positive lymphocytes were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.
Baseline, Week 12
Secondary Outcomes (5)
Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) at Week 12
Baseline, Week 12
Average Change in Fractional Exhaled Nitric Oxide (FeNO) From Baseline to Week 6 Through Week 12
From Baseline to Week 6 through Week 12
Number of Participants With Antidrug Antibodies (ADA)
From Baseline up to 24 weeks
Pharmacokinetics (PK) Assessment: Serum Functional Dupilumab Concentration
Week 0, Week 2, 6, 8, 12, 18, End of study (Week 24)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Baseline up to Week 24
Study Arms (2)
Placebo
PLACEBO COMPARATORPlacebo (for dupilumab), 2 subcutaneous injections on Day 1 (Week 1) as a loading dose followed by a single injection q2w from Week 2 to Week 14, added to stable inhaled corticosteroid/ long-acting beta-agonist (ICS/LABA) therapy. Salbutamol/albuterol or Levosalbutamol/levalbuterol was given as reliever medication.
Dupilumab
EXPERIMENTALDupilumab, 2 subcutaneous injections on Day 1 as a loading dose for a total of 600 mg, followed by a single 300 mg injection q2w from Week 2 to Week 14, added to stable ICS/LABA therapy. Salbutamol/albuterol or Levosalbutamol/levalbuterol was given as reliever medication.

Eligibility Criteria
You may qualify if:
- Male and female adults with a physician diagnosis of persistent asthma for ≥12 months.
- Existing treatment with medium to high dose inhaled corticosteroids in combination with a long-acting beta agonist for at least 3 months with a stable dose ≥1 month prior to Visit 1 (Screening Visit).
- Treatment with a third asthma controller for at least 3 months with a stable dose \>=1 month prior to Visit 1 was allowed.
- Pre-bronchodilator forced expiratory volume (FEV1) 55 to 85% of predicted normal.
You may not qualify if:
- Participants \<18 years or \>65 years.
- Fractional exhaled nitric oxide (FeNO) \<26 parts per billion (ppb) at Visit 1 (Screening Visit).
- Chronic obstructive pulmonary disease or other lung diseases (eg, idiopathic pulmonary fibrosis, eosinophilic granulomatosis with polyangiitis \[Churg-Strauss Syndrome\]) which could impair lung function.
- A participant who experienced an asthma exacerbation that resulted in emergency treatment, hospitalization due to asthma, or treatment with systemic steroids at any time from 1 month prior to Visit 1.
- A participant who had experienced an upper or lower respiratory tract infection within the 4 weeks prior to Visit 1.
- Evidence of lung disease(s) other than asthma.
- Previous smoker (smoking history \>10 pack-years) or current smoker (within 6 months prior to Visit 1).
- Comorbid disease that might interfere with the evaluation of investigational medicinal product or conduct of study procedures (e.g., bronchoscopy).
- Anti-immunoglobulin E (IgE) therapy (omalizumab) or any other biologic therapy within 6 months of Visit 1.
- Exposure to another investigative study medication within a time period prior to Visit 1 that is less than 5 half-lives of the study medication.
- Treatment with systemic (oral or injectable) corticosteroids within 28 days of Visit 1.
- The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
