    In the difficult-to-treat subgroup of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and comorbid aspirin-exacerbated respiratory disease, dupilumab significantly improved CRSwNP disease outcomes, along with asthma control and lung function. This is preliminary evidence of the effect of dupilumab in patients with CRSwNP and comorbid aspirin- exacerbated respiratory disease

    Data mining of free-text responses : an innovative approach to analyzing patient perspectives on treatment for chronic rhinosinusitis with nasal polyps in a phase IIa proof-of-concept study for dupilumab

    Purpose: Patient perspective is an important and increasingly sought-after complement to clinical assessment. The aim of this study was to transcribe individual patients' experience of treatment in a dupilumab clinical trial through free-text responses with analysis using natural language processing (NLP) to obtain the unique perspective of patients on disease impact and unmet needs with existing treatment to inform future trial design. Patients and Methods: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) who were enrolled in a Phase IIa randomized controlled trial comparing dupilumab with placebo (NCT01920893) were invited to complete a self-assessment of treatment (SAT) tool at the end of treatment, asking, "What is your opinion on the treatment you had during the trial? What did you like or dislike about the treatment?" Free-text responses were analyzed for the overall cohort and according to treatment assignment using natural language processing including sentiment scoring. In a mixed-methods approach, quantitative patient-reported outcome (PRO) results were utilized to complement the qualitative analysis of free-text responses. Results: Of 60 patients enrolled in the study, 43 (71.6%) completed the SAT and responses from 37 patients were analyzed (placebo, n = 16; dupilumab, n = 21). Word analyses showed that the most common words were "smell," "improve," "staff," "great," "time," and "good." Across the whole cohort, "smell" was the most common symptom-related word. The words "smell" and "experience" were more likely to occur in patients treated with dupilumab. Patients treated with dupilumab also had more positive sentiment in their SAT responses than those who received placebo. The results from this qualitative analysis were reflected in quantitative PRO results. Conclusion: "Smell" was important to patients with CRSwNP, highlighting its importance as a patient-centric efficacy outcome measure in the context of clinical trials in CRSwNP.

    Background The human monoclonal antibody dupilumab blocks interleukin (IL)-4 andIL-13, key and central drivers of type 2 inflammation. Dupilumab, on background mometasone furoate nasal spray (MFNS), improved outcomes in the phase III SINUS-52 study (NCT02898454) in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP). This posthoc analysis of SINUS-52 examined whether eosinophilic status of CRSwNP was a predictor of dupilumab efficacy. Methods Patients were randomized 1:1:1 to dupilumab 300 mg every 2 weeks (q2w) until week 52; dupilumab 300 mg q2w until Week 24, then 300 mg every 4 weeks until week 52; or placebo (MFNS) until week 52. Coprimary endpoints were change from baseline in nasal polyps score (NPS), nasal congestion (NC), and Lund-Mackay score assessed by CT (LMK-CT) at week 24. Patients (n = 438) were stratified by eosinophilic chronic rhinosinusitis (ECRS) status according to the Japanese Epidemiological Survey of Refractory Eosinophilic Rhinosinusitis algorithm. Results Dupilumab significantly improved NPS, NC, and LMK-CT scores versus placebo at week 24 in all ECRS subgroups (p 0.05), except LMK-CT at week 24 (p = 0.0275). Similar results were seen for the secondary endpoints. Dupilumab was well tolerated across all ECRS subgroups. Conclusion Dupilumab produced consistent improvement in symptoms of severe CRSwNP irrespective of ECRS status. Therefore, blood eosinophil level may not be a suitable biomarker for dupilumab efficacy in CRSwNP

    Dupilumab improves health related quality of life:Results from the phase 3 SINUS studies

    Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2-mediated inflammatory disease with high symptom burden and reduced health-related quality of life (HRQoL). This report aimed to comprehensively understand the effects of dupilumab on domains of HRQoL, their individual elements, and health status in patients with severe CRSwNP from phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) trials. Methods Patients were randomized to dupilumab (n = 438) or placebo (n = 286) for 24 weeks (SINUS-24), or 52 weeks (SINUS-52). Disease-specific HRQoL using 22-item sino-nasal outcome test (SNOT-22), and health status using EuroQoL-visual analog scale (EQ-VAS) was evaluated in the pooled intention-to-treat (ITT) population (Week 24), SINUS-52 ITT (Week 52) and in the subgroups with/without asthma; non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD); and prior sinus surgery. Results At baseline, patients had poor disease-specific HRQoL and general health status and identified "Decreased sense of smell/taste" and "Nasal blockage" as the most important symptoms. Dupilumab significantly improved SNOT-22 total, domain (Nasal, Sleep, Function, Emotion, and Ear/facial), and 22-item scores, and EQ-VAS, at Week 24 vs placebo (all p < .0001), with continued improvements to Week 52 in SINUS-52. Improvements occurred irrespective of comorbid asthma, NSAID-ERD, or prior surgery. A significantly greater proportion of dupilumab-treated patients exceeded clinically meaningful thresholds for SNOT-22 total score and EQ-VAS vs placebo (all subgroups p < .05 except patients without surgery at Week 24). Conclusions Dupilumab treatment led to significant clinically meaningful improvements across all aspects of disease-specific HRQoL, and general health status in patients with severe CRSwNP
