Clinical Trial Summary

Primary Objective:

To evaluate the efficacy of dupilumab 300 mg every 2 weeks (q2w) compared to placebo on a background of mometasone furoate nasal spray (MFNS) in reducing nasal congestion (NC)/obstruction severity and endoscopic nasal polyp score (NPS) in participants with bilateral nasal polyps (NP). In addition for Japanese participants, reduction in computed tomography (CT) scan opacification of the sinuses was a co-primary objective.

Secondary Objectives:

- To evaluate the efficacy of dupilumab in improving total symptoms score.

- To evaluate the efficacy of dupilumab in improving sense of smell.

- To evaluate the efficacy of dupilumab in reducing CT scan opacification of the sinuses (primary objective for Japanese participants).

- To evaluate ability of dupilumab in reducing proportion of participants who required treatment with systemic corticosteroids (SCS) or surgery for NP.

- To evaluate the effect of dupilumab on participant reported outcomes and health related quality of life.

- To evaluate the efficacy of dupilumab 300 mg q2w up to Week 52.

- To evaluate the efficacy of dupilumab 300 mg q2w up to Week 24 followed by 300 mg every 4 weeks (q4w) up to Week 52.

- To evaluate the effect of dupilumab in the subgroups of participants with prior surgery and comorbid asthma including non-steroid anti-inflammatory drug exacerbated respiratory disease.

- To evaluate the safety of dupilumab in participants with bilateral NP.

- To evaluate functional dupilumab concentrations (systemic exposure) and incidence of treatment emergent anti-drug antibodies.


Description:

The total study duration per participant was up to 68 weeks that consisted of a 4-weeks run-in period, 52-weeks treatment period, and a 12-weeks post treatment period.

Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline at Week 24 in Nasal Congestion/Obstruction Symptom Severity Score 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. All participants randomized to receive Dupilumab had been on 300 mg q2w regimen until Week 24 and analyzed as a pooled population for Week 24 assessments. Baseline, Week 24
Primary Change From Baseline at Week 24 in Nasal Polyp Score 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. All participants randomized to receive Dupilumab had been on 300 mg q2w regimen until Week 24 and analyzed as a pooled population for Week 24 assessments. Baseline, Week 24
Secondary Change From Baseline at Week 24 in Opacification of Sinuses Measured by Lund Mackay (LMK) Score 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. All participants randomized to receive Dupilumab had been on 300 mg q2w regimen until Week 24 and analyzed as a pooled population for Week 24 assessments. Baseline, Week 24
