Primary Outcome Measures :
  1. Change From Baseline at Week 24 in Nasal Congestion/Obstruction Symptom Severity Score [ Time Frame: Baseline, Week 24 ]
    NC symptom severity was assessed by the participants on a daily basis from Visit 1 and throughout the study using an e-diary on a scale of 0 to 3, where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms, with higher scores indicated more severity. Least squares (LS) means and standard error (SE) were obtained from Analysis of covariance (ANCOVA) model described in Statistical Analysis Overview.

  2. Change From Baseline at Week 24 in Nasal Polyp Score [ Time Frame: Baseline, Week 24 ]
    NPS: sum of right, left nostril scores, evaluated by nasal endoscopy. For each nostril, NPS was graded based on polyp size from 0 = no polyps to 4 = large polyps causing complete obstruction of inferior nasal cavity; lower score = smaller-sized polyps. Total NPS: sum of right and left nostril scores; ranges from 0 (no polyps) to 8 (large polyps), higher score = more severe disease. NPS was assessed by centralized, blinded, independent review of the nasal endoscopy video recordings. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview.


Secondary Outcome Measures :
  1. Change From Baseline at Week 24 in Opacification of Sinuses Measured by Lund-Mackay (LMK) Score [ Time Frame: Baseline, Week 24 ]
    The LMK scoring system rated each of both the left and right frontal, maxillary, sphenoid, ostiomeatal complex, anterior ethmoid and posterior ethmoid sinuses using following grading: 0 = normal, 1 = partial opacification, 2 = total opacification. The total score was the sum of scores from each side and ranges from 0 (normal) to 24 (more opacified); higher score indicated more severe disease. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview. NOTE: For Japan regulatory submission only, this endpoint is not included as a secondary outcome measure and is instead one of the co-primary outcome measures.

  2. Change From Baseline at Week 24 in Total Symptom Score (TSS) [ Time Frame: Baseline, Week 24 ]
    The TSS was the sum of participant-assessed nasal symptom scores for nasal congestion/obstruction, decreased/loss of sense of smell, and rhinorrhea (anterior/posterior nasal discharge), each accessed on 0-3 categorical scale (where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms). Total score ranged from 0 (no symptoms) to 9 (severe symptoms). Higher score indicated more severe symptoms. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview.

  3. Change From Baseline at Week 24 in the University of Pennsylvania Smell Identification Test (UPSIT) Score [ Time Frame: Baseline, Week 24 ]
    The UPSIT was a 40-item test to measure the individual's ability to detect odors. Total score ranges from 0 (anosmia) to 40 (normal sense of smell), lower score indicated severe smell loss. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview.

  4. Change From Baseline at Week 24 in Severity of Decreased/Loss of Smell as Assessed by Participant Daily [ Time Frame: Baseline, Week 24 ]
    The severity of decreased/loss of sense of smell was reported by the participants using a 0 to 3 categorical scale (where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms), higher score indicated more severe symptoms. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview.

  5. Change From Baseline at Week 24 in 22-item Sino-nasal Outcome Test (SNOT-22) Scores [ Time Frame: Baseline, Week 24 ]
    The SNOT-22 is a validated questionnaire that was used to assess the impact of chronic rhinosinusitis phenotype with nasal polyps (CRSwNP) on health-related quality of life (HRQoL). It is a 22 item questionnaire with each item assigned a score ranging from 0 (no problem) to 5 (problem as bad as it can be). The total score may range from 0 (no disease) to 110 (worst disease), lower scores representing better health related quality of life. LS means and SE were obtained from ANCOVA model described in Statistical Analysis Overview.

  6. Rescue Treatment Use: Estimate of Percentage of Participants With >=1 Event by Week 24 Obtained Using Kaplan-Meier Method [ Time Frame: Baseline up to Week 24 ]

    Rescue treatment was defined as usage of systemic corticosteroids (SCS) or NP surgery (actual or planned) during the treatment period. Rescue treatment included:

    • SCS: Betamethasone, dexamethasone, dexamethasone sodium phosphate, Hydrocortisone sodium succinate, methylprednisolone, prednisolone, prednisolone metasulfobenzoate sodium, prednisone, and triamcinolone.

  • Ongoing symptoms (for at least 8 weeks prior to Visit [V] 1) of nasal congestion/blockage/obstruction with moderate or severe symptom severity (score 2 or 3) at V1 and a weekly average severity of greater than 1 at the time of randomization (V2), and another symptom such as loss of smell, rhinorrhea (anterior/posterior).
  • Signed written informed consent.

Exclusion criteria:

  • Participants <18 years of age.
  • Participants who were previously treated in dupilumab studies.
  • Participants who had taken:
  • Biologic therapy/systemic immunosuppressant to treat inflammatory disease or autoimmune disease (eg, rheumatoid arthritis, inflammatory bowel disease, primary biliary cirrhosis, systemic lupus erythematosus, multiple sclerosis, etc.) within 2 months before V1 or 5 half-lives, whichever was longer.
  • Any experimental monoclonal antibody (mAB) within 5 half-lives or within 6 months before V1 if the half-life was unknown.
  • Anti-immunoglobulin E (IgE) therapy (omalizumab) within 130 days prior to V1.
  • Participants who received leukotriene antagonists/modifiers at V1 unless they were on a continuous treatment for at least 30 days prior to V1.
  • Initiated allergen immunotherapy within 3 months prior to V1 or planned to begin therapy or changed its dose during the run-in period or the randomized treatment period.
  • Participants who undergone any intranasal and/or sinus surgery (including polypectomy) within 6 months prior to V1.
  • Participants who had a sinonasal or sinus surgery changing the lateral wall structure of the nose making impossible the evaluation of NPS.
  • Participants with conditions/concomitant diseases making them nonevaluable at V1 or for the primary efficacy endpoint such as:
  • Antrochoanal polyps;
  • Nasal septal deviation that would occlude at least one nostril;
  • Acute sinusitis, nasal infection or upper respiratory infection;
  • Ongoing rhinitis medicamentosa;
  • Allergic granulomatous angiitis (Churg-Strauss syndrome), granulomatosis with polyangiitis (Wegener's granulomatosis), Young's syndrome, Kartagener's syndrome or other dyskinetic ciliary syndromes, concomitant cystic fibrosis;
  • Radiologic suspicion, or confirmed invasive or expansive fungal rhinosinusitis.
  • Participants with nasal cavity malignant tumor and benign tumors (eg, papilloma, blood boil, etc).
  • Participants with forced expiratory volume in 1 second (FEV1) 50% or less (of predicted normal).
  • Participants who received concomitant treatment prohibited in the study.
  • Treatment with a live (attenuated) vaccine within 12 weeks before the baseline visit.
  • History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening.
  • Positive with hepatitis B surface antigen (HBsAg) or hepatitis C antibody at the screening visit.
  • Active chronic or acute infection requiring systemic treatment within 2 weeks before the baseline visit.
  • Known or suspected history of immunosuppression.
  • Pregnant or breastfeeding women, or women planned to become pregnant or breastfeed during the study.
  • Women unwilling to use adequate birth control, if of reproductive potential and sexually active.
