In phase 3 QUEST (NCT02414854), dupilumab vs placebo significantly reduced asthma exacerbation rates (AER) and improved pre-bronchodilator forced expiratory volume in 1 second (FEV1) in patients with uncontrolled, moderate-to-severe asthma, with greater effects in patients with elevated T2 biomarkers (≥ 150 eosinophils/μL or fractional exhaled nitric oxide [FeNO] ≥ 25 parts per billion). Overall safety was consistent with the known dupilumab safety profile. This post hoc analysis assessed dupilumab efficacy in QUEST patients with T2 asthma with evidence of an allergic phenotype (baseline serum IgE ≥ 30 IU/mL and aeroallergen-specific IgE ≥ 0.35 IU/mL) by number of aeroallergen sensitizations: 1, 2, 3, or ≥ 4. Non-sensitized patients (serum total IgE < 30 IU/mL without evidence of allergic phenotype) were also assessed.Patients and Methods: Endpoints were annualized AER, change from baseline in pre-bronchodilator FEV1 and asthma control (5-item Asthma Control Questionnaire [ACQ-5]), and FeNO and serum total IgE levels over the 52-week treatment period.Results: In all subgroups by number of allergens sensitized, dupilumab vs placebo reduced AER by 35– 67% and improved both pre-bronchodilator FEV1 at Week 12 (least squares mean differences: 0.10– 0.26 L across subgroups) and ACQ-5 score at Week 52 (– 0.26 to – 0.43). Dupilumab significantly reduced FeNO and total IgE levels at Week 52 compared with placebo. Similar results were observed in non-sensitized patients.Conclusion: Dupilumab improved clinical outcomes and reduced biomarker levels in patients with uncontrolled, moderate-to-severe T2 asthma irrespective of allergen sensitization status or number.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02414854.Keywords: dupilumab, allergic asthma, type 2 asthma, perennial aeroallergen

Transient increases in blood eosinophil counts have been observed in dupilumab clinical trials.To assess eosinophil counts and eosinophilia-related treatment-emergent adverse events (TEAEs) across 11 dupilumab clinical trials, comparing adult and adolescent patients with asthma and adult patients with chronic rhinosinusitis with nasal polyps (CRSwNP), atopic dermatitis, and eosinophilic esophagitis.Eosinophil counts, rates of eosinophilia-related TEAEs or treatment-emergent eosinophilia (1,500 cells/μL), discontinuations, clinical symptoms, and efficacy in patients with asthma or CRSwNP with treatment-emergent eosinophilia are presented.Transient increases in mean eosinophil counts were observed in dupilumab-treated patients with asthma (mean range across studies at baseline: 349-370 cells/μL; week 4: 515-578 cells/μL), CRSwNP (baseline: 440-448 cells/μL; week 16: 595 cells/μL), and atopic dermatitis (baseline: 434-600 cells/μL; week 4: 410-710 cells/μL), followed by a decline starting by week 24 to baseline or lower. No increases were seen in patients with eosinophilic esophagitis (baseline: 310 cells/μL; week 4: 230 cells/μL). In dupilumab-treated patients across all studies, rates of eosinophilia TEAEs were 0% to 13.6%. Clinical symptoms associated with increased eosinophils were rare (seven of 4,666 dupilumab-treated patients, including six cases of eosinophilic granulomatosis with polyangiitis) and occurred only in patients with asthma or CRSwNP. Eosinophilia was not associated with reduced dupilumab efficacy.Transient increases in eosinophil counts with dupilumab treatment did not affect efficacy and were rarely of clinical consequence. It remains important for physicians to base judgment on individual patient history and baseline eosinophil counts and to be alert to hypereosinophilic symptoms.

Eosinophilic esophagitis (EoE) is a chronic, progressive, type 2 inflammatory disease of increasing prevalence, characterized by symptoms of dysphagia and reduced quality of life. A dysregulated type 2 immune response to food and aeroallergen leads to barrier dysfunction, chronic esophageal inflammation, remodeling, and fibrosis. Patients with EoE have impaired quality of life because of dysphagia and other symptoms. They may also suffer social and psychological implications of food-related illness and expensive out-of-pocket costs associated with treatment. Disease burden in EoE is often compounded by the presence of comorbid type 2 inflammatory diseases. Current conventional treatments include elimination diet, proton pump inhibitors, and swallowed topical corticosteroids, as well as esophageal dilation in patients who have developed strictures. These treatments demonstrate variable response rates and may not always provide long-term disease control. There is an unmet need for long-term histologic, endoscopic, and symptomatic disease control; for targeted therapies that can normalize the immune response to triggers, reduce chronic inflammation, and limit or prevent remodeling and fibrosis; and for earlier diagnosis, defined treatment outcomes, and a greater understanding of patient perspectives on treatment. In addition, healthcare professionals need a better understanding of the patient perspective on disease burden, the disconnect between symptoms and disease activity, and the progressive nature of EoE and the need for continuous monitoring and maintenance treatment. In this review, we explore the progression of disease over the patient's lifespan, highlight the patient perspective on disease, and discuss the unmet need for effective long-term treatments.

BACKGROUND: Patients with asthma and/or chronic rhinosinusitis with nasal polyps (CRSwNP) experience recurrent respiratory tract infections. Dupilumab targets type 2 inflammation, a common underlying pathophysiology of both conditions, with proven efficacy. OBJECTIVE: To examine investigator-reported respiratory infection adverse events and anti-infective medication use with dupilumab versus placebo in patients with moderate-to-severe asthma or severe CRSwNP. METHODS: We performed a post hoc analysis of the pivotal phase 3 trials LIBERTY ASTHMA QUEST (NCT02414854) and LIBERTY NP SINUS-52 (NCT02898454) in moderate-to-severe asthma and severe CRSwNP, respectively. RESULTS: Investigator-reported respiratory infection events occurred at a significantly lower incidence in patients treated with dupilumab versus placebo, in both asthma (22% lower; P < .0001; 95% CI 0.71-0.85) and CRSwNP (38% lower; P

Data are lacking on the comparative health status of patients with CRSwNP. This analysis compared baseline physical and mental health-related quality of life (HRQoL) and overall health status of patients with severe CRSwNP enrolled in a Phase 3 clinical trial with general population norms and with other chronic diseases.Methods: In this post hoc cross-sectional analysis of baseline data from the SINUS-24 study (NCT02912468), HRQoL was measured using the 36-item Short Form (SF-36) questionnaire and general health status was measured using the EuroQol-5 Dimension visual analog scale (EQ-VAS). Analyses included the intention-to-treat (ITT) population and subgroups defined by prior sinonasal surgery, systemic corticosteroid use, and coexisting asthma or non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD). Scores were compared with published values for population norms (50 for SF-36 physical component summary (PCS) and mental component summary (MCS), 70.4− 83.3 for EQ-VAS) and for rheumatoid arthritis, type 2 diabetes, and asthma.Results: In the ITT population (n=276), mean SF-36 physical component summary (PCS), SF-36 mental component summary (MCS), and EQ-VAS scores were below general population norms (46.4, 48.6, and 66.0, respectively). Mean SF-36 PCS and EQ-VAS scores were below population norms across all subgroups; mean SF-36 MCS scores were below the population norm in all subgroups except no prior surgery. SF-36 PCS and MCS scores from SINUS-24 were generally similar to other chronic diseases, except SF-36 PCS which was lower in rheumatoid arthritis. EQ-VAS scores in SINUS-24 were lower than in other chronic diseases. HRQoL scores weakly correlated with objective measures of disease severity.Conclusion: In patients with severe CRSwNP, including those with coexisting asthma/NSAID-ERD, HRQoL was worse than population norms and as burdensome as diseases such as type 2 diabetes, asthma, and rheumatoid arthritis.Graphical Abstract: Keywords: chronic rhinosinusitis with nasal polyps, health-related quality of life, symptom burden

Severe asthma impacts quality of life (QoL), including dyspnea, sleep, and activity limitation. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4/-13, key and central drivers of type 2 inflammation. Phase 3 VENTURE (NCT02528214) and TRAVERSE open-label extension (NCT02134028) evaluated dupilumab 300 mg vs placebo every 2 weeks for 24 weeks (VENTURE) and dupilumab only for an additional 48-96 weeks (TRAVERSE) in patients with oral corticosteroid (OCS)-dependent severe asthma.To assess dupilumab's impact on Asthma Quality of Life Questionnaire (AQLQ) items related to breathing symptoms, sleep, and activity limitation, and on OCS reduction.Proportion of patients with AQLQ scores of 6/7 for breathing symptoms-, sleeping-, and activity-related items in VENTURE and TRAVERSE, together with OCS dose reductions in VENTURE.In VENTURE, significantly greater proportions of dupilumab- vs placebo-treated patients achieved scores of 6/7 by week 24 in breathing symptoms- (42.7-60.2% vs 22.4-39.3%), sleeping- (45.6-65.0% vs 27.1-47.7%), and activity-related (44.7-51.5% vs 22.4-34.6%) AQLQ items. Improvements were maintained through TRAVERSE in the dupilumab/dupilumab group and increased to dupilumab treatment levels in the placebo/dupilumab group. Significant OCS dose reductions were observed in VENTURE; up to 90% and 60% of dupilumab- vs 65% and 41% of placebo-treated patients with AQLQ scores of 6/7 in breathing symptoms-, sleeping-, and activity-related items achieved ≥50% dose reduction and eliminated OCS at week 24, respectively.In patients with severe OCS-dependent asthma, dupilumab improved QoL related to breathing symptoms, sleep, and activity limitation, and reduced OCS use.

The 52-week, phase 3 LIBERTY ASTHMA QUEST study (NCT02414854) in patients aged above or equal to 12 years with uncontrolled, moderate-to-severe asthma demonstrated the efficacy and safety of dupilumab 200 mg and 300 mg every 2 weeks vs matched placebo.To assess whether dupilumab improves clinical outcomes in QUEST patients with persistent airflow obstruction (PAO) defined as post-bronchodilator forced expiratory volume in 1 second/forced vital capacity ratio less than 0.7 at baseline.End points were annualized rate of severe exacerbations, pre and post-bronchodilator forced expiratory volume in 1 second over time, proportion achieving reversal of PAO, and quality of life. Efficacy was evaluated in patients with or without PAO at baseline in subpopulations with eosinophils ≥ 150 cells/µL or fractional exhaled nitric oxide (FeNO) ≥ 25 ppb or eosinophils ≥ 300 cells/µL and FeNO ≥ 25 ppb.Of 1902 patients enrolled in QUEST, 1039 (55%) had PAO at baseline. Dupilumab vs placebo rapidly and significantly improved lung function in patients with PAO and elevated type 2 inflammatory biomarkers at baseline. Dupilumab improved probability of reversing airflow obstruction (hazard ratio vs placebo 1.616 [95% confidence interval, 1.272-2.052] and 1.813 [1.291-2.546]; both P.001) and significantly reduced severe exacerbations by 69% (relative risk, 0.411; 95% confidence interval [0.327-0.516]; P.0001) and by 75% (0.252 [0.178-0.356]; P.0001) in patients with PAO with eosinophils ≥ 150 cells/µL or FeNO ≥ 25 ppb and eosinophils ≥ 300 cells/µL and FeNO ≥ 25 ppb, respectively. Similar results were observed in patient subgroups without PAO.In patients with uncontrolled moderate-to-severe asthma, treatment with dupilumab facilitates reversal of PAO status and improves clinical outcomes.ClinicalTrials.gov identifier: NCT02414854.

Although eosinophils are the hallmark of eosinophilic esophagitis (EoE) with threshold levels required for diagnosis, their exact role in EoE is unclear. The EoE-Endoscopic Reference Score (EREFS) assesses endoscopic inflammatory (edema/exudate/furrows) and remodeling (rings/strictures) features. We assessed the correlations between peak esophageal intraepithelial eosinophil count (eos/high-power field [hpf]) and EREFS in placebo-treated EoE patients from two clinical trials: phase 2 proof-of-concept (POC; NCT02379052; n = 24) and part A of phase 3 TREET (Phase3-PartA; NCT03633617; n = 39). POC was a 12-week trial in adults and Phase3-PartA was a 24-week trial in adults and adolescents. Endoscopic examination of the esophagus was performed at baseline (BL) and end of treatment (EOT) and scored for inflammatory and remodeling subscores and total score using EREFS (higher scores indicate greater severity). Peak eos/hpf was measured from pinch biopsies of proximal, mid, and distal esophagus at BL and EOT. Pearson correlations were performed between total/proximal/mid/distal eos/hpf and EREFS total, subscores, and components at BL, EOT, and for change from BL at EOT. Some strong correlations (r > 0.5) were observed between total peak eos/hpf and EREFS at BL in both studies and at EOT in Phase3-Part A (Table). Moderate-to-strong correlations (r > 0.3) were observed between total peak eos/hpf and EREFS inflammation subscore and edema/exudates/furrows individual components (some P > 0.5) in both studies. Correlations of total peak eos/hpf with EREFS remodeling subscore and rings/stricture components were not significant (P = 0.07–0.94). Peak eos/hpf in the proximal, mid, or distal esophagus were more strongly associated with EREFS inflammation subscore (majority moderate-to-strong correlations; P = 0.001–0.66) than EREFS remodeling subscore (weak correlations, P = 0.22–0.99) at BL/EOT for both studies. In these EoE patients, moderate-to-strong correlations were observed between eos/hpf and endoscopic markers of inflammation. No strong correlations were observed between total, proximal, mid, or distal peak eos/hpf and endoscopic parameters of remodeling. These data support a role for intact eosinophils in inflammatory changes in the esophagus in EoE and demonstrate the need for both histology and endoscopic evaluation. Further study, with larger sample sizes, is required to verify these findings in other contexts.

The Histologic Scoring System (HSS) assesses severity/extent of histologic features (eosinophil density [ED]/basal zone hyperplasia [BZH]/eosinophil abscesses [EA]/eosinophil surface layering [SL]/surface epithelial alteration [SEA]/dyskeratotic epithelial cells [DEC]/dilated intercellular spaces [DIS]/lamina propria fibrosis [LPF]) in eosinophilic esophagitis (EoE). The Endoscopic Reference Score (EREFS) assesses endoscopic feature severity (edema/exudates/furrows/rings/strictures). We correlated HSS components with inflammatory/remodeling EREFS components in placebo-treated EoE patients from 2 trials—phase 2 proof-of-concept (POC; NCT02379052), phase 3 TREET part A (Phase3-PartA; NCT03633617). POC was a 12-week trial in adults, and Phase3-PartA was a 24-week trial in adults and adolescents. Proximal/mid/distal esophagus biopsies were collected at baseline/end of treatment (EOT) and scored by HSS for grade (severity)/stage (extent)/components (higher scores = greater severity). Endoscopies were scored by EREFS (higher scores = greater severity) and inflammatory (edema+exudates+furrows) and remodeling (rings+stricture) subscores calculated. Pearson correlation and single co-variate regression model analyses were performed between baseline HSS grade/stage, total/individual components scores and EREFS total/components scores and subscores, and for the change in scores from baseline at EOT (ΔEOT). Moderate-to-strong correlations (r > 0.3) were observed between total EREFS and HSS grade/stage for baseline/ΔEOT in POC and baseline in Phase3-PartA (Table). Moderate correlations were observed between BZH and EREFS remodeling subscore and rings for ΔEOT in Phase3-PartA; DIS grade and EREFS remodeling subscore and strictures for baseline and ΔEOT in POC but not Phase3-PartA; and EREFS inflammation and remodeling subscores and components for SEA and SL at baseline and ΔEOT in POC. Moderate-to-strong correlations were observed between EREFS inflammation subscore and DIS stage and between edema and DIS grade/stage at baseline in both studies. Similar results were observed using regression analyses. Specific components of HSS and EREFS, reflecting inflammatory and remodeling processes, are closely correlated, when examined by Pearson correlations or regression analyses, and can aid identification of fibrostenotic or inflammatory phenotypes in EoE. Correlations of DIS with endoscopic inflammatory and remodeling features reflect the role of barrier dysfunction in maintaining chronic inflammation that ultimately leads to remodeling.

Coexisting chronic rhinosinusitis and nasal polyps (CRS-NPs) substantially increases the disease burden of asthma. Dupilumab, a fully human monoclonal antibody, has established efficacy and an acceptable safety profile in asthma and CRS with NP.To evaluate long-term dupilumab efficacy in TRAVERSE (NCT02134028) patients with uncontrolled, moderate-to-severe (QUEST) or oral corticosteroid (OCS)-dependent (VENTURE) asthma with or without coexisting CRS-NP.In TRAVERSE, 317 of 1530 (21%) QUEST and 61 of 187 (48%) VENTURE patients had self-reported CRS-NP; they received subcutaneous 300 mg dupilumab every 2 weeks up to 96 weeks. Patients were categorized by parent study treatment group (placebo/dupilumab, dupilumab/dupilumab). End points included annualized asthma exacerbation rates and mean change from parent study baseline in prebronchodilator forced expiratory volume in 1 second, Asthma Control Questionnaire 5 score, Asthma Quality of Life Questionnaire score, and OCS dose.Patients with coexisting CRS-NP had higher OCS dose and a history of more exacerbations. Concluding TRAVERSE, exacerbation rates decreased from 2.39 to 0.32 and 2.32 to 0.35 in dupilumab/dupilumab and 2.36 to 0.41 and 2.36 to 0.45 in placebo/dupilumab by week 96 from QUEST and VENTURE baselines, respectively. Non-CRS-NP results were similar. Improvements in forced expiratory volume in 1 second, Asthma Control Questionnaire 5 score, and Asthma Quality of Life Questionnaire score during parent studies were maintained in TRAVERSE; placebo/dupilumab patients achieved similar improvements to dupilumab/dupilumab by week 48. By week 96, 71% and 39% of OCS-dependent patients with CRS-NP and 83% and 47% without CRS-NP treated with dupilumab/dupilumab and placebo/dupilumab, respectively, stopped OCS.Long-term dupilumab efficacy was maintained in patients with asthma with or without self-reported coexisting CRS-NP, including OCS-sparing effects observed in OCS-dependent severe asthma.ClinicalTrials.gov Identifiers: NCT02528214, NCT02414854, and NCT02134028.

These post hoc analyses investigated disease-specific health-related quality of life (HRQoL) and general health status in the randomized, placebo-controlled QUEST study (NCT02414854) in patients treated with dupilumab for moderate-to-severe asthma with comorbid CRS. Patients received 300 mg of dupilumab or placebo every 2 weeks for 52 weeks. CRS HRQoL was assessed by the 22-item Sino-Nasal Outcome Test (SNOT-22; items scored 0– 5). The 22 items are categorized into 5 domains (nasal, ear/facial, sleep, function, and emotion), and patients report the top 5 most important items affecting their health. General health status was assessed by Euro-QoL visual analog scale (EQ-VAS). Of 1902 patients, 382 (20.1%) self-reported comorbid CRS; 193 patients receiving dupilumab 300 mg q2w or matched placebo were included in this analysis. At baseline, the most impacted SNOT-22 domain was nasal, and general health status was below population norms. Patients rated “decreased sense of taste/smell,” “nasal blockage,” “cough,” “reduced productivity,” and “wake up tired” as the 5 most important SNOT-22 items affecting their health. Percentage change from baseline in SNOT-22 total score was significantly greater for dupilumab vs placebo at Weeks 24, 36, and 52 (all p < 0.05). Improvements from baseline were significantly greater for dupilumab vs placebo at Week 52 for all SNOT-22 domains (p < 0.05), except emotion. At Week 52, significant changes from baseline with dupilumab vs placebo were observed for all 5 most important SNOT-22 items affecting their health (all p < 0.05). EQ-VAS was significantly improved with dupilumab vs placebo by Week 12, with improvements sustained to Week 52 (all p < 0.01). In patients with moderate-to-severe asthma who self-reported comorbid CRS, dupilumab treatment vs placebo improved CRS-specific HRQoL and general health status.Keywords: asthma, chronic rhinosinusitis, nasal polyps, dupilumab, health-related quality of life, SNOT-22

Fractional exhaled nitric oxide (FeNO) may have a role both as a prognostic and predictive biomarker, in combination with eosinophils, for assessing responsiveness to some biological therapies.We evaluated the value of baseline FeNO, adjusted for baseline blood eosinophil levels and other clinical characteristics, as an independent predictor of treatment response to dupilumab in patients with uncontrolled, moderate-to-severe asthma.We performed a post-hoc analysis of LIBERTY ASTHMA QUEST (NCT02414854), a phase 3, double-blind study in patients aged ≥ 12 years with uncontrolled moderate-to-severe asthma who received dupilumab 200/300 mg, or placebo every 2 weeks up to 52 weeks. Annualized event rate (AER) of severe exacerbations and least squares mean change from baseline in pre-bronchodilator forced expiratory volume in 1 s (FEVAER increased with increasing baseline FeNO in placebo, and decreased in dupilumab groups. The relative risk of severe exacerbations was 22·7%, 58·3%, and 69·3% lower for dupilumab vs placebo for the FeNO25, 25 to50, and ≥ 50 ppb subgroups. The magnitude of FEVIncreased baseline FeNO was associated with greater clinical effects in dupilumab vs placebo, independent of eosinophil levels and other clinical characteristics.

Safety and efficacy data for dupilumab beyond 1 year are lacking for patients from Japan with moderate-to-severe asthma.The TRAVERSE open-label extension (OLE) study (NCT02134028) assessed the safety and efficacy of dupilumab 300 mg every 2 weeks up to 96 weeks in 2282 patients who completed a previous dupilumab asthma study. The primary endpoint was incidence of treatment-emergent adverse events (TEAEs). Secondary endpoints included annualized severe exacerbation rate and change from parent study baseline in pre-bronchodilator forced expiratory volume in 1 second (FEVTEAEs were consistent with the parent studies and the known safety profile of dupilumab. One patient permanently discontinued treatment due to TEAEs. Exacerbation rates remained low and were sustained to Week 96, as were improvements in pre-bronchodilator FEVLong-term dupilumab treatment was well tolerated and efficacious in patients with non-OCS-dependent, moderate-to-severe asthma recruited from Japan.

BACKGROUND: Type 2 inflammatory diseases often coexist in patients. Dupilumab targets type 2 inflammation and has demonstrated treatment benefits in patients with atopic dermatitis (AD), asthma, and chronic rhinosinusitis with nasal polyps (CRSwNP) with an acceptable safety profile. OBJECTIVE: This post hoc analysis across five phase 3 studies in patients with moderate to severe AD or asthma, or severe CRSwNP, evaluated time of onset and duration of the treatment response. METHODS: Patients received subcutaneous dupilumab 200/300 mg or placebo. Assessments included the Eczema Area and Severity Index, Peak Pruritus Numerical Rating Scale, and Dermatology Life Quality Index in AD; pre-bronchodilator FEV1, daily morning peak expiratory flow, and symptom scores in asthma; and University of Pennsylvania Smell Identification Test, daily nasal congestion, and loss of smell scores in CRSwNP. RESULTS:At week 2 after the initiation of dupilumab versus placebo, 67.8% versus 36.5% of AD patients achieved a clinically meaningful benefit (Eczema Area and Severity Index: 50% or greater improvement; Peak Pruritus Numerical Rating Scale: 3 point or greater improvement; or Dermatology Life Quality Index: 4 point or greater improvement) (P < .001). Moreover, 61.6% versus 39.9% of asthma patients achieved improvements in pre-bronchodilator FEV1 of 100 mL or greater and 48.8% versus 26.3% achieved 200 mL or greater improvement (both P < .001); 33.2% versus 5.6% of CRSwNP patients regained a sense of smell (P < .001). Treatment effects further improved or were sustained to the end of treatment. CONCLUSIONS: Clinically meaningful responses were achieved rapidly after the first dupilumab dose in AD, asthma, or CRSwNP and were sustained throughout treatment (see Video in this article's Online Repository at www.jaci-inpractice.org).

While advances in asthma care have been made in Latin America, there is still a large unmet need in patients with uncontrolled asthma. This post hoc analysis of the QUEST study assessed safety and efficacy of dupilumab in the subgroup of patients enrolled in Latin American countries with a type 2 inflammatory asthma phenotype (blood eosinophils ≥ 150cells/µL or FeNO ≥25ppb). LIBERTY ASTHMA QUEST (NCT02414854) was a phase 3, multinational, randomized, double-blind, placebo-controlled study in patients with uncontrolled, moderate-to-severe asthma. Eligible patients ≥ 12 years of age were randomized in a 2:2:1:1 ratio to receive 52 weeks of add-on subcutaneous dupilumab 200 or 300 mg every 2 weeks or matched-volume placebos. Pre-specified co-primary efficacy endpoints were the annualized rate of severe exacerbations during the treatment period and the change from baseline in pre-bronchodilator FEV1 at treatment week 12. Asthma control, changes in asthma biomarker levels, and dupilumab safety were also evaluated. 530 (27.9% of the overall QUEST population; dupilumab: 353, placebo: 177) Latin-American patients were recruited; 420 (79.2%) had a type 2 inflammatory asthma phenotype. Dupilumab vs placebo reduced the annualized rate of severe exacerbations by 52.7% (P < 0.001) and increased pre-bronchodilator FEV1 at week 12 by 0.15 L (P < 0.001), in the type 2 population. Safety was consistent with the known dupilumab safety profile. Consistent with the results in the overall population, dupilumab reduced the risk of severe asthma exacerbations and improved lung function in Latin American patients with uncontrolled, moderate-to-severe asthma and a type 2 phenotype.

This post hoc analysis of SINUS-24/-52 investigated the direction and magnitude of within-patient change in these endpoints over time.Methods: NPS (scale 0– 8) was assessed at Weeks 4, 8, 16, 24, 40, and 52 in SINUS-52 and Weeks 8, 16, and 24 in SINUS-24. Daily patient-reported NC scores (0 [no symptoms]– 3 [severe symptoms]) were averaged over 28 days. Within-patient changes from baseline were assessed through Week 24 in pooled SINUS-24/-52 (n = 438/286 dupilumab/SOC) and through Week 52 in SINUS-52 (n = 150/153).Results: In SINUS-52, NPS improved in 70.0% of dupilumab-treated patients at Week 4 vs 31.8% with SOC (odds ratio [OR] 5.2 [95% confidence interval 3.1– 8.8]) and 78.7% vs 28.2% at Week 52 (OR 10.6 [6.0– 18.7]) (all p < 0.0001). NC improved in 73.3% of dupilumab-treated patients at Week 4 vs 46.7% with SOC (OR 3.2 [2.0– 5.3]) and 86.9% vs 50.7% at Week 52 (OR 6.4 [3.5– 11.5]) (all p < 0.0001). Clinically meaningful (≥ 1 point) improvements in NPS occurred in 55.7% and 72.3% of dupilumab-treated patients at Weeks 4 and 52, respectively, vs 16.9% and 16.2% with SOC. Clinically meaningful (≥ 1 point) improvements in NC occurred in 16.7% and 67.6% of dupilumab-treated patients at Weeks 4 and 52, respectively, vs 3.9% and 20.8% with SOC. At Week 52, NPS worsening from baseline was observed in 5.7% of dupilumab-treated patients vs 40.1% with SOC and NC worsening in 2.1% vs 20.8%, respectively.Conclusion: Dupilumab provided rapid, continuing, and clinically relevant improvements over time in NPS and NC in most patients with severe CRSwNP in the SINUS studies.Graphical Abstract: Keywords: chronic rhinosinusitis with nasal polyps, dupilumab, nasal polyp score, nasal congestion

Type 2 cytokines interleukin (IL)-4/IL-5/IL-13 play an important role in pathogenesis of type 2 conditions, including asthma. Dupilumab, a human monoclonal antibody, blocks the shared receptor component for IL-4/IL-13, inhibiting signaling. In phase 2b (P2B) (NCT01854047) and phase 3 VENTURE (NCT02528214), dupilumab reduced annualized severe exacerbations rates (AER), improved forced expiratory volume in one second (FEVPost-hoc assessment of dupilumab efficacy vs placebo in P2B and VENTURE in patients stratified by allergic status.Allergic asthma was defined as total serum immunoglobulin E (IgE) ≥30 IU/mL and ≥1 perennial aeroallergen-specific IgE ≥0.35 kU/L at baseline. AER, pre-bronchodilator (BD) FEVIn patients with allergic asthma, dupilumab (P2B: pooled 200/300mg; VENTURE: 300mg) every 2 weeks vs placebo reduced AER (P2B: -60%, P.01; VENTURE: -72%, P.001), and, in P2B, increased pre-BD FEVDupilumab significantly reduced AER and improved lung function and asthma control and HRQoL in patients with or without evidence of allergic asthma.

The Global Initiative for Asthma report recommends consideration of add-on biologics for patients with type 2 inflammation (blood eosinophils ≥150 cells/μL, fractional exhaled nitric oxide [Feno] ≥20 parts per billion or allergic asthma) whose asthma cannot be controlled by high-dose inhaled corticosteroids. In QUEST (NCT02414854), add-on dupilumab versus placebo was efficacious in patients with uncontrolled, moderate to severe asthma, including those with eosinophils greater than or equal to 150 cells/μL and/or Feno greater than or equal to 25 parts per billion.To assess dupilumab efficacy in patients with a type 2 phenotype in the presence or absence of allergic asthma phenotype.Patients aged 12 years or older received add-on dupilumab 200/300 mg versus matched placebo every 2 weeks for 52 weeks. Allergic asthma phenotype was defined as baseline serum total IgE greater than or equal to 30 IU/mL and 1 or more perennial aeroallergen-specific IgE level greater than or equal to 0.35 kU/L. Annualized rate of severe asthma exacerbations and changes from study baseline in prebronchodilator and postbronchodilator FEVOf 1902 patients in QUEST, 83.3% had eosinophils and/or Feno above Global Initiative for Asthma thresholds; 56.9% had evidence for allergic asthma. Dupilumab significantly reduced the rate of severe asthma exacerbations in patients with (48.8%) and without (64.0%) evidence of allergic asthma and improved prebronchodilator and postbronchodilator FEVIn patients with type 2 biomarkers over Global Initiative for Asthma thresholds, dupilumab significantly reduced exacerbations and improved lung function. Efficacy was not impacted by allergic status.

Dupilumab blocks the shared receptor component for interleukin (IL)-4/IL-13, key and central drivers of type 2 inflammation in multiple diseases.

This study was conducted to validate the System for Observing Fitness Instruction Time (SOFIT) for measuring physical activity levels of high-school students. Thirty-five students (21 girls and 14 boys from grades 9-12) completed a standardized protocol including lying, sitting, standing, walking, running, curl-ups, and push-ups. Heart rates and Energy Expenditure, that is, oxygen uptake, served as concurrent validity criteria. Results indicate that SOFIT discriminates accurately among high-school students’ sedentary behaviors (i.e., lying down, sitting, standing) and moderate to vigorous physical activity behavior and is recommended for use in research and assessment of physical activity levels in physical education classes for this age group. Implications for use of SOFIT by both researchers and teachers in physical education are described, as well.

The purpose of this study was to assess the validity of the System for Observing Fitness Instruction Time (SOFIT) for measuring physical activity of elementary and middle school children. Students (N = 173,92 boys and 81 girls) from Grades 1–8 completed a standardized protocol that included lying, sitting, standing, walking, running, curl-ups, and push-ups. Heart rates were used as a criterion for concurrent validity. The results confirm the validity of the physical activity codes of SOFIT for elementary and middle school children. Activity Categories 2–5 indicate different levels of energy expenditure, whereas Categories 1 (lying) and 2 (sitting) refer to the same energy expenditure level. The common distinction between SOFIT Levels 4 and 5 as MVPA (moderate to vigorous physical activity) and SOFIT Levels 1 to 3 as non-MVPA is valid. Curl-ups and push-ups should be coded as MVPA.
