Primary Outcome Measures :
  1. Change from baseline in sinus opacifications assessed by computerized tomography (CT) scans using the Lund Mackay (LMK) score at Week 52 [ Time Frame: Baseline to Week 52 ]
    LMK total score is based on assessment of the CT scan findings for each sinus area. The extent of opacification is rated between 0 (normal) to 24 (total opacification).


Secondary Outcome Measures :
  1. Change from baseline in sinus opacifications assessed by CT scans using the LMK score at Week 24 [ Time Frame: Baseline to Week 24 ]
    LMK total score is based on assessment of the CT scan findings for each sinus area. The extent of opacification is rated between 0 (normal) to 24 (total opacification).

  2. Proportion of patients who receive systemic corticosteroids (SCS) and/or undergo/plan to undergo surgery for AFRS during the planned study treatment period [ Time Frame: Baseline to Week 52 ]
  3. Change from baseline in monthly average nasal congestion/obstruction score from the Nasal symptom Diary at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    The nasal congestion/obstruction scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').

  4. Change from Baseline in the monthly average anterior/posterior rhinorrhea score from the Nasal Symptom Diary at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    The rhinorrhea scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').

  5. Change from baseline in endoscopic NPS compared to placebo at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    The total nasal polyps score (NPS) is the sum of the right and left nostrils, ranging from 0 (no polyps) to 8 (large polyps causing complete obstruction).

  6. Change from baseline in 22-item sino-nasal outcome test (SNOT-22) total score at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    SNOT-22 is a patient-reported outcome (PRO) questionnaire. Score ranges from 0 to 110 with higher score indicating greater rhinosinusitis related health burden.

  7. Change from baseline in monthly average total symptom score (TSS) derived from the Nasal Symptom Diary at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    TSS ranges from 0 to 9. Higher scores on the TSS indicate greater symptom severity.

  8. Change from baseline in visual analog scale (VAS) rhinosinusitis at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    VAS score ranges from 0 ('not troublesome') to 10 ('worst thinkable troublesome').

  9. Change from baseline in University of Pennsylvania smell identification test (UPSIT) at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    The UPSIT score ranges from 0 to 40, with 40 being the best possible score.

  10. Change from baseline in the score of decreased/loss of smell using the Nasal Symptom Diary at Week 24 and Week 52 [ Time Frame: Baseline to Week 24 and Week 52 ]
    The decreased/loss of smell scores are scored from 0 ('No symptoms') to 3 ('Severe symptoms').

  11. Change from baseline to Week 52 in three Dimensional CT volumetric measurement of the paranasal sinuses [ Time Frame: Baseline to Week 52 ]
  12. Incidence of treatment-emergent adverse events (TEAEs) or serious adverse events (SAEs) [ Time Frame: Baseline to Week 64 ]
  13. Dupilumab concentration in serum over time [ Time Frame: Baseline to Week 52 ]
  14. Percent change from baseline in total IgE in serum compared to placebo over the 52 weeks treatment period [ Time Frame: Baseline to Week 52 ]
  15. Percent change from baseline in fungal-specific IgE in serum compared to placebo over the 52 weeks treatment period [ Time Frame: Baseline to Week 52 ]
  16. Incidence of treatment-emergent anti-drug antibodies (ADA) to dupilumab over time [ Time Frame: Baseline to Week 64 ]
