RESUMO
OBJECTIVES: To assess the severity of the top 5 22-item Sino-Nasal Outcome Test (SNOT-22) items ranked most important by patients with chronic rhinosinusitis with nasal polyps (CRSwNP), the effect of dupilumab on these items, and their association with objective disease measures. STUDY DESIGN: Post hoc analysis of the SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) clinical trials. SETTING: Multinational, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies. METHODS: Patients ranked the SNOT-22 items most affecting their health at baseline. Item symptom severity (0-5 scale) was assessed at baseline, Week 24 (W24), and Week 52 (W52). Changes in nasal polyps score (NPS) and Lund-Mackay (LMK) scores were assessed in patients with/without SNOT-22 items improvements of at least 1 severity group point at W24 and W52. RESULTS: The SNOT-22 items ranked most important at baseline were "decreased sense of smell/taste" (87% of patients), followed by "nasal blockage" (82%), "postnasal discharge" (40%), "thick nasal discharge" (37%), and "wake up at night" (26%); 82%, 61%, 32%, 40%, and 26% of patients reported severe symptoms (score 4 or 5) for these items, respectively. Dupilumab improved score severity for all top 5 items versus placebo at W24 and W52. Improvements in NPS and LMK scores were numerically greater in patients with improvements in the SNOT-22 top 5 items. CONCLUSION: Loss of smell/taste was ranked as the most important symptom by patients with CRSwNP. Dupilumab reduced the severity of the top 5 most important SNOT-22 items versus placebo, in parallel with improvements in objective disease measures. CLINICAL TRIAL REGISTRATION: SINUS-24 and SINUS-52 clinical trials were registered with ClinicalTrials.gov, identifiers NCT02912468 and NCT02898454, respectively.

Purpose: Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4/-13, key and central drivers of type 2 inflammation in multiple diseases. This post hoc analysis of the Phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959) evaluated the efficacy of dupilumab in children aged 6 to 11 years with moderate-to-severe asthma with a type 2 inflammatory phenotype (blood eosinophil count ≥150 cells/µL or fractional exhaled nitric oxide [FeNO] ≥20 ppb) and a history of 1, 2, or ≥3 prior exacerbations. The impact of baseline type 2 biomarker levels on the efficacy of dupilumab in this population was also investigated. Patients and Methods: Patients were stratified by the number of exacerbations in the prior year (1, 2, or ≥3) and level of FeNO or blood eosinophil count at baseline. Endpoints included rate of severe exacerbations, percentage of non-exacerbators, and change from baseline in both lung function parameters (pre- and post-bronchodilator [BD] percent predicted forced expiratory volume in 1 s (ppFEV1) and ppFEV1/forced vital capacity [FVC] ratio) and Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) score. Results: A total of 350 patients were included in this analysis. Across patients with 1, 2, or ≥3 prior exacerbations and different levels of type 2 biomarkers, dupilumab reduced the risk of severe asthma exacerbations vs placebo by 53.0-96.0% and improved both pre-BD ppFEV1 and pre-BD FEV1/FVC ratio at Week 52. Dupilumab led to significant reductions in ACQ-7-IA scores in all groups of patients by Week 52. Conclusion: In children with uncontrolled, moderate-to-severe asthma with a type 2 phenotype, dupilumab consistently reduced the risk of asthma exacerbations, improved lung function, and reduced ACQ-7-IA scores, regardless of exacerbation history.
RESUMO
BACKGROUND: Previous clinical trials have demonstrated dupilumab efficacy and safety in adults and adolescents with moderate to severe asthma for up to 3 years. OBJECTIVE: The TRAVERSE continuation study (NCT03620747), a single-arm, open-label study, assessed safety and tolerability of dupilumab 300 mg every 2 weeks up to an additional 144 weeks (â¼3 years) in patients with moderate to severe asthma who previously completed TRAVERSE (NCT02134028). METHODS: Primary end points were incidence and event rates per 100 patient-years of treatment-emergent adverse events (TEAEs). Secondary end points included adverse events (AEs) of special interest, serious AEs, and AEs leading to study discontinuation. RESULTS: A total of 393 patients participated in the TRAVERSE continuation study (cumulative dupilumab exposure, 431.7 patient-years; median treatment duration, 309 days). A total of 29 patients (7.4%) received more than 958 days of treatment. A total of 214 (54.5%) patients reported at least 1 TEAE (event rate: 171.4); 37 (9.4%) experienced at least 1 treatment-related TEAE, none of which were considered severe; 2 patients reported 6 TEAEs of moderate intensity. A total of 22 (5.6%) patients reported serious AEs (event rate: 6.9). AEs of special interest were reported in 24 patients (6.1%; event rate: 6.0). Five (1.3%) deaths occurred (event rate: 1.2) following serious AEs of coronavirus disease 2019 (COVID-19)-related pneumonia (3 patients), pancreatitis (1 patient), and pulmonary embolism (1 patient). None of the TEAEs leading to death were considered treatment-related. CONCLUSIONS: Dupilumab treatment was well tolerated for up to an additional 3 years. Safety findings were consistent with the known safety profile of dupilumab. These findings further support the long-term use of dupilumab in patients with moderate to severe asthma.

BACKGROUND: Changes from baseline in fractional exhaled nitric oxide (FeNO) and blood eosinophil count (Eos) may be related to efficacy outcomes in dupilumab-treated patients with moderate-to-severe asthma. OBJECTIVE: This post hoc analysis investigated biomarker changes in placebo- and dupilumab-treated patients with uncontrolled moderate-to-severe asthma enrolled in QUEST (NCT02414854). METHODS: Spline analyses of annualized severe exacerbation rate (AER) and change from baseline in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV1) at week 52 were performed as a function of the fold change in FeNO at week 52 and the maximum fold change in Eos over weeks 0-12 (also change from baseline in pre-BD FEV1 at week 12). RESULTS: The combined placebo and dupilumab groups comprised 638 and 1264 patients, respectively. FeNO levels declined rapidly by week 2 and then gradually to week 52 in patients treated with dupilumab versus placebo; Eos, after initially increasing with dupilumab, declined slightly from baseline in both treatment groups. AER during QUEST showed no significant association with the change in biomarkers in either treatment group. The change from baseline in pre-BD FEV1 at week 52 was inversely associated with the fold change in FeNO in both groups, with a significant difference between the dupilumab and placebo curves (P = .014), and was positively associated with the fold change in Eos in both groups (P = .022). CONCLUSIONS: Relative changes in FeNO and Eos were not associated with AER, regardless of treatment arm. However, changes in both biomarkers showed a predictive value for lung function improvement; for FeNO, this was specific to the dupilumab treatment arm.

Background: Severe, uncontrolled asthma and asthma exacerbations in children are associated with abnormal lung function and airway development, and increased risk of chronic obstructive lung disease in adulthood. The rationale for this post hoc analysis was to explore the relationship between changes in asthma exacerbation rates and lung function in children treated with dupilumab. Methods: This post hoc analysis included children aged 6 to 11 years with uncontrolled, moderate-to-severe type 2 asthma (blood eosinophils ≥150 cells/µL or fractional exhaled nitric oxide ≥20 ppb) who received dupilumab or placebo in the phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959). Endpoints were the proportion of patients achieving clinically meaningful improvements (≥5% or ≥10%) in pre-bronchodilator percent-predicted forced expiratory volume in 1 second (ppFEV1) by Week 12, annualized severe asthma exacerbation rates from Week 12-52, and mean change from baseline in ppFEV1 to Week 12. Results: At Week 12 of VOYAGE, 141/236 (60%) of children treated with dupilumab and 57/114 (50%) of children receiving placebo showed improvements of ≥5% in ppFEV1; 106/236 (45%) children receiving dupilumab and 36/114 (32%) receiving placebo achieved improvements in ppFEV1 ≥10%. During the Week 12-52 treatment period, dupilumab vs placebo significantly reduced severe exacerbation rates in all subgroups by 52-60% (all P<0.05). Dupilumab treatment resulted in rapid and sustained improvements in ppFEV1 (Week 12 least squares mean difference [95% CI] vs placebo: 3.54 [0.30, 6.78] percentage points; P=0.03) in children who achieved improvements of ≥5%. Conclusion: Dupilumab vs placebo significantly improved pre-bronchodilator ppFEV1, with a higher proportion of patients achieving a clinically meaningful response at Week 12. Dupilumab also significantly reduced severe exacerbation rates, independent of pre-bronchodilator ppFEV1 response at Week 12. Trial Registration: NCT02948959.
RESUMO
Purpose: Dupilumab significantly reduced the requirement for systemic corticosteroids (SCS) in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP). Patients with CRSwNP and coexisting asthma typically have a higher disease burden and have more difficulty in managing disease. Here, we report an analysis of asthma outcomes and SCS use in patients with CRSwNP and coexisting asthma. Patients and Methods: This was a post hoc analysis of the randomized, placebo-controlled SINUS-24 and SINUS-52 studies (NCT02912468/NCT02898454) in patients with severe CRSwNP and coexisting asthma (patient self-reported) from the pooled intention-to-treat population randomized to dupilumab 300 mg every 2 weeks or placebo. On-treatment SCS use was estimated using Kaplan-Meier analysis. Forced expiratory volume in 1 s (FEV1), percent predicted FEV1, and the 6-item Asthma Control Questionnaire (ACQ-6) were assessed at baseline and Week 24 (pooled SINUS-24/52) in patients with/without history of asthma exacerbation or prior SCS use. Results: Of 337 patients with coexisting asthma, 88 (26%) required on-treatment SCS use. The requirement for on-treatment SCS use for any reason was significantly lower with dupilumab (20/167 patients; 12%) vs placebo (68/170; 40%); hazard ratio (95% confidence interval) 0.248 (0.150-0.409); p < 0.0001. The most frequent reasons for SCS use were nasal polyps (dupilumab 3% and placebo 27%) and asthma (2% and 9%, respectively). FEV1, percent predicted FEV1, and ACQ-6 were all significantly improved at Week 24 with dupilumab vs placebo irrespective of history of asthma exacerbation or prior SCS use (all p < 0.01). Conclusion: Dupilumab significantly reduced the requirement for SCS and improved asthma outcomes irrespective of history of asthma exacerbation or prior SCS use vs placebo in patients with CRSwNP and coexisting asthma, demonstrating concomitant reduction of SCS use and asthma disease burden in these patients.
