          -  Sinus opacification in CT scan with an LMK score of 9 for patients with unilateral
             polyps or 12 for patients with bilateral polyps during screening period and,
        Body weight ≥15 kg
        Exclusion Criteria:

          -  Known of fungal invasion into sinus tissue.
          -  Severe concomitant illness(es) that, in the investigator's judgment, would adversely
             affect the patient's participation in the study
          -  Active tuberculosis or non-tuberculous mycobacterial infection, or a history of
             incompletely treated tuberculosis unless documented adequately treated.
          -  Diagnosed active endoparasitic infections; suspected or high risk of endoparasitic
             infection
          -  Known or suspected immunodeficiency
          -  Active chronic or acute infection requiring treatment with systemic antibiotics,
             antivirals, or antifungals within 2 weeks before the Screening Visit 1 or during the
             screening period.
          -  History of systemic hypersensitivity or anaphylaxis to dupilumab or any of its
             excipients.
          -  Treatment with commercially available dupilumab within 12 months, participation in
             prior dupilumab clinical trial, or discontinued dupilumab use due to adverse event.

             emitting devices/stents; nasal spray using exhalation delivery system, such as
             Xhance™, during screening period.
