ALL PRIMARY AND KEY SECONDARY ENDPOINTS WERE MET WITH STATISTICAL SIGNIFICANCE1,2
Patients enrolled received background INCS throughout the
duration of both trials1,2

SINUS-24
(N=276) 24 WEEKS

Randomized
DUPIXENT + INCS
300 mg Q2W for 24 weeks (n=143)

Placebo + INCS for 24 weeks (n=133)

Study population

Adults (≥18 years) on background INCSf with CRSwNP despite prior sinus surgery or prior treatment with (unless ineligible to receive or intolerant to) SCS in the past 2 years

Patients with chronic rhinosinusitis without nasal polyps were not included in these trials

Rescue with SCS or surgery was allowed at investigators’ discretion

The total population of patients in SINUS-24 and SINUS-52 was unrestricted by minimum baseline blood eosinophil count

Coprimary endpoints

Change from baseline at Week 24 in:
  • NC score averaged over 28 days
  • Bilateral endoscopic NPS

Key secondary endpoints

Change from baseline at Week 24 in:

  • Daily LoS score
  • LMK-CT score
  • SNOT-22 score
  • UPSIT score

Other secondary endpoints

Prespecified pooled analysis

Change from baseline at Week 24 in proportion of patients requiring SCS or sinus surgery

SINUS-52
(N=448) 52 WEEKS

Randomized

DUPIXENT + INCS
300 mg Q2W for 52 weeks (n=150)d

DUPIXENT + INCS
300 mg Q2W for 24 weeks, followed by Q4We through Week 52 (n=145)d

Placebo + INCS for 52 weeks (n=153)

~79% of patients enrolled in both trials had atopic diseases. In SINUS-24 and SINUS-52, all subjects had evidence of sinus opacification on the LMK sinus CT scan, and 73% to 90% of subjects had opacification of all sinuses. Patients with prior surgery had a mean of 2.0 prior surgeries, and patients with prior SCS use had a mean of 1.6 SCS courses in the previous 2 years.

dIn SINUS-52, data from baseline to Week 24 are pooled from DUPIXENT 300 mg Q2W treatment arms (n=295).2

eThe recommended dose of DUPIXENT for CRSwNP is 300 mg given subcutaneously every other week.1

fAll patients in the placebo and DUPIXENT arms were on a background therapy of INCS, mometasone furoate nasal spray.2

gHigher scores indicate greater disease severity.1
