b Week 24 in SINUS-52. LSM difference between DUPIXENT 300 mg Q2W + INCS (n=295, pooled arms) and placebo + INCS (n=153): -5.13 (95% CI: -5.80, -4.46)
(-5.21 from a baseline score of 18.12 vs -0.09 from a baseline score of 17.65, respectively) (P<0.0001).2

c Nominal improvement observed at Week 52 in LMK-CT score.2

d Week 52 in SINUS-52. LSM difference between DUPIXENT 300 mg Q2W + INCS (n=150) and placebo + INCS (n=153): -6.94 (95% CI: -7.87, -6.01) (-6.83 from a
baseline score of 18.42 vs 0.11 from a baseline score of 17.65, respectively).2

DUPIXENT DEMONSTRATED SUBSTANTIAL REDUCTIONS IN
OPACIFICATION ACROSS ALL INDIVIDUAL SINUSES AT WEEK 242

Lund-Mackay computed tomography (LMK-CT) score (range 0 to 24): reduced score indicates improvement.1

INCS, intranasal corticosteroid; LSM, least squares mean; Q2W, once every 2 weeks.

Use of DUPIXENT for the CRSwNP indication in patients aged 12-17 years is supported by evidence from studies of DUPIXENT as add-on maintenance
treatment in adults with inadequately controlled CRSwNP.1
