Baseline Characteristics of Patients With Chronic Rhinosinusitis With Nasal Polyps (With and Without Asthma) Enrolled in SINUS-52, a Randomized, Double-Blind, Phase 3 Study of Dupilumab
Research sponsored by Sanofi and Regeneron Pharmaceuticals, Inc. ClinicalTrials.gov Identifier: NCT02898454. Medical writing/editorial assistance provided by Sinéad Holland, PhD, of Excerpta Medica, funded by Sanofi Genzyme and Regeneron Pharmaceuticals, Inc.Introduction:
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2-mediated inflammatory disease associated with a high symptom burden and poor health-related quality of life. Dupilumab, a human IL-4Rα mAb inhibiting IL-4 and IL-13, key drivers of type 2-mediated inflammation, is approved for uncontrolled moderate-to-severe atopic dermatitis in adults, and in the USA for patients (pts) aged ≥12 years with moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma. In a phase 2a study, dupilumab improved endoscopic, radiologic, clinical, patient-reported sinonasal, and asthma outcomes in CRSwNP. We present baseline characteristics of CRSwNP pts on daily intranasal mometasone furoate from a dupilumab phase 3 study (SINUS-52; NCT02898454).
Methods:
Pts were randomized 1: 1: 1 to subcutaneous placebo every 2 weeks (q2w) for 52 weeks, dupilumab 300 mg q2w for 52 weeks, or dupilumab 300 mg q2w (first 24 weeks) followed by every 4 weeks (last 28 weeks).
Results:
Of 448 pts, 37.7% were female (mean [SD] age 52.0 [12.5] years). Mean CRSwNP duration was 10.9 [9.6] years, 58.3% pts had ≥1 prior sinonasal surgery, 80.1% received systemic corticosteroids in the 2 years prior. 82.4% of pts had a type 2 comorbidity history, including asthma (59.6%) and N-ERD (26.8%). Mean [SD] scores at baseline were: nasal polyp, 6.1 [1.2]; nasal congestion, 2.4 [0.6]; SNOT-22, 51.9 [20.9]; UPSIT, 13.6 [8.0]; CT Lund-Mackay, 18.0 [3.8]; visual analogue scale for symptom severity, 8.0 [2.1].
Conclusions:
Overall baseline disease characteristics in the SINUS-52 study demonstrate a population with severe CRSwNP inadequately controlled with standard of care, highlighting a need for additional therapeutic options. Most pts had asthma or other type 2 comorbidities.
