RESUMO
BACKGROUND: Blood eosinophils and fractional exhaled nitric oxide (Feno) are prognostic biomarkers for exacerbations and predict lung function responses to dupilumab in adolescents and adults with asthma. OBJECTIVE: We evaluated the relationship between baseline blood eosinophils and Feno and response to dupilumab in children with asthma. METHODS: Children aged 6 to 11 years with uncontrolled moderate-to-severe asthma (n = 408) were randomized to receive dupilumab 100/200 mg by body weight or volume-matched placebo every 2 weeks for 52 weeks. Annualized exacerbation rate (AER) reduction and least squares mean change in prebronchodilator percent predicted forced expiratory volume in 1 second (ppFEV1) at week 12 were assessed according to cutoff baseline levels for Feno (<20 ppb vs ≥20 ppb) and blood eosinophil count (<150, ≥150 to <300, ≥300 to <500, and ≥500 cells/µL). Quadrant analyses in populations defined by biomarker thresholds and spline models across continuous end points assessed the relationship with Feno and eosinophil count. Interaction testing evaluated the independent roles of Feno and blood eosinophils as predictive markers. RESULTS: Exacerbation risk and magnitude of AER reduction increased in subgroups with higher baseline biomarker levels. Quadrant analyses revealed that disease of patients with either elevated Feno or eosinophil counts demonstrated a clinical response to dupilumab. Interaction testing indicated blood eosinophil counts or Feno independently added value as predictive biomarkers. CONCLUSIONS: In children with uncontrolled moderate-to-severe asthma, blood eosinophil counts and Feno are clinically relevant biomarkers to identify those at risk for asthma exacerbations, as well as those with disease with clinical response to dupilumab.

BACKGROUND: Monoclonal antibodies targeting IgE, interleukin-4 and -13, and interleukin-5 are effective in treating severe type 2 asthma, but new targets are needed. Itepekimab is a new monoclonal antibody against the upstream alarmin interleukin-33. The efficacy and safety of itepekimab as monotherapy, as well as in combination with dupilumab, in patients with asthma are unclear. METHODS: In a phase 2 trial, we randomly assigned, in a 1:1:1:1 ratio, adults with moderate-to-severe asthma receiving inhaled glucocorticoids plus long-acting beta-agonists (LABAs) to receive subcutaneous itepekimab (at a dose of 300 mg), itepekimab plus dupilumab (both at 300 mg; combination therapy), dupilumab (300 mg), or placebo every 2 weeks for 12 weeks. After randomization, LABA was discontinued at week 4, and inhaled glucocorticoids were tapered over weeks 6 through 9. The primary end point was an event indicating a loss of asthma control, assessed in the itepekimab group and the combination group, as compared with the placebo group. Secondary and other end points included lung function, asthma control, quality of life, type 2 biomarkers, and safety. RESULTS: A total of 296 patients underwent randomization. By 12 weeks, an event indicating a loss of asthma control occurred in 22% of the patients in the itepekimab group, 27% of those in the combination group, and 19% of those in the dupilumab group, as compared with 41% of those in the placebo group; the corresponding odds ratios as compared with placebo were as follows: in the itepekimab group, 0.42 (95% confidence interval [CI], 0.20 to 0.88; P = 0.02); in the combination group, 0.52 (95% CI, 0.26 to 1.06; P = 0.07); and in the dupilumab group, 0.33 (95% CI, 0.15 to 0.70). As compared with placebo, the forced expiratory volume in 1 second before bronchodilator use increased with the itepekimab and dupilumab monotherapies but not with the combination therapy. Itepekimab treatment improved asthma control and quality of life, as compared with placebo, and led to a greater reduction in the mean blood eosinophil count. The incidence of adverse events was similar in all four trial groups. CONCLUSIONS: Interleukin-33 blockade with itepekimab led to a lower incidence of events indicating a loss of asthma control than placebo and improved lung function in patients with moderate-to-severe asthma.

BACKGROUND: Children with moderate-to-severe asthma continue to have disease complications despite the receipt of standard-of-care therapy. The monoclonal antibody dupilumab has been approved for the treatment of adults and adolescents with asthma as well as with other type 2 inflammatory diseases. METHODS: In this 52-week phase 3, randomized, double-blind, placebo-controlled trial, we assigned 408 children between the ages of 6 and 11 years who had uncontrolled moderate-to-severe asthma to receive a subcutaneous injection of dupilumab (at a dose of 100 mg for those weighing ≤30 kg and 200 mg for those weighing >30 kg) or matched placebo every 2 weeks. All the children continued to receive a stable dose of standard background therapy. The primary end point was the annualized rate of severe asthma exacerbations. Secondary end points included the change from baseline in the percentage of predicted prebronchodilator forced expiratory volume in 1 second (ppFEV1) at week 12 and in the score on the Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) at week 24. End points were evaluated in the two primary efficacy populations who had either a type 2 inflammatory asthma phenotype (≥150 blood eosinophils per cubic millimeter or a fraction of exhaled nitric oxide of ≥20 ppb at baseline) or a blood eosinophil count of at least 300 cells per cubic millimeter at baseline. RESULTS: In patients with the type 2 inflammatory phenotype, the annualized rate of severe asthma exacerbations was 0.31 (95% confidence interval [CI], 0.22 to 0.42) with dupilumab and 0.75 (95% CI, 0.54 to 1.03) with placebo (relative risk reduction in the dupilumab group, 59.3%; 95% CI, 39.5 to 72.6; P<0.001). The mean (±SE) change from baseline in the ppFEV1 was 10.5±1.0 percentage points with dupilumab and 5.3±1.4 percentage points with placebo (mean difference, 5.2 percentage points; 95% CI, 2.1 to 8.3; P<0.001). Dupilumab also resulted in significantly better asthma control than placebo (P<0.001). Similar results were observed in the patients with an eosinophil count of at least 300 cells per cubic millimeter at baseline. The incidence of serious adverse events was similar in the two groups. CONCLUSIONS: Among children with uncontrolled moderate-to-severe asthma, those who received add-on dupilumab had fewer asthma exacerbations and better lung function and asthma control than those who received placebo.

BACKGROUND: Cytokines, such as interleukins (IL)-4/5/13, play a key role in multiple type 2 inflammatory diseases, including allergic asthma. Dupilumab, a human monoclonal antibody, blocks the shared receptor component for IL-4/IL-13, inhibiting signaling. In this post hoc analysis of VOYAGE (NCT02948959), dupilumab efficacy was evaluated in patients aged 6-11 years with type 2 asthma with or without evidence of allergic asthma (baseline serum total IgE ≥30 IU/mL and ≥1 perennial aeroallergen-specific IgE ≥0.35kU/L). METHODS: Annualized severe exacerbation rates (AER) and changes in pre-bronchodilator (Pre-BD) forced expiratory volume in one second (FEV1 ), percent-predicted pre-BD FEV1 (ppFEV1 ), and Asthma Control Score (ACQ)-7 were assessed during the treatment period. RESULTS: 350 children (261 with and 89 without evidence of allergic asthma) were included. Dupilumab versus placebo significantly reduced AER in patients with (0.24 vs. 0.62, relative risk reduction [RRR]: 62% [95% CI, 39-76], P < .0001) and without (0.39 vs. 0.80, RRR: 51% [95% CI, 0-76], P < .05) evidence of allergic asthma. Significant improvements in ppFEV1 , pre-bronchodilator FEV1 , and ACQ-7 scores were observed in dupilumab versus placebo throughout the treatment period in patients with evidence of allergic asthma. In patients without evidence of allergic asthma, numerical improvements in pre-bronchodilator FEV1 and asthma control were observed by Week 52. CONCLUSION: Dupilumab versus placebo reduced asthma exacerbations in children with type 2 asthma irrespective of evidence of allergic asthma; similar trends were observed in changes in lung function. Significant improvement in asthma control was observed in patients with evidence of allergic asthma, but not in those without.

BACKGROUND: 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. OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: In patients with uncontrolled moderate-to-severe asthma, treatment with dupilumab facilitates reversal of PAO status and improves clinical outcomes.

OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

BACKGROUND: In the phase III SYNAPSE study, mepolizumab reduced nasal polyp (NP) size and nasal obstruction in chronic rhinosinusitis with NP. OBJECTIVE: We sought to assess the efficacy of mepolizumab in patients from SYNAPSE grouped by comorbid asthma, aspirin-exacerbated respiratory disease (AERD), and baseline blood eosinophil count (BEC). METHODS: SYNAPSE, a randomized, double-blind, 52-week study (NCT03085797), included patients with severe bilateral chronic rhinosinusitis with NP eligible for surgery despite intranasal corticosteroid treatment. Patients received 4-weekly subcutaneous mepolizumab 100 mg or placebo plus standard of care for 52 weeks. Coprimary end points were change in total endoscopic NP score (week 52) and nasal obstruction visual analog scale score (weeks 49-52). Subgroup analyses by comorbid asthma and AERD status, and post hoc by BEC, were exploratory. RESULTS: Analyses included 407 patients (289 with asthma; 108 with AERD; 371 and 278 with BEC counts ≥150 or ≥300 cells/µL, respectively). The proportion of patients with greater than or equal to 1-point improvement from baseline in NP score was higher with mepolizumab versus placebo across comorbid diseases (asthma: 52.9% vs 29.5%; AERD: 51.1% vs 20.6%) and baseline BEC subgroups (<150 cells/µL: 55.0% vs 31.3%; ≥150 cells/µL: 49.5% vs 28.1%; <300 cells/µL: 50.7% vs 29.0%; ≥300 cells/µL: 50.4% vs 28.1%). A similar trend was observed in patients without comorbid asthma or AERD. More patients had more than 3-point improvement in nasal obstruction VAS score with mepolizumab versus placebo across comorbid subgroups. CONCLUSIONS: Mepolizumab reduced polyp size and nasal obstruction in chronic rhinosinusitis with NP regardless of the presence of comorbid asthma or AERD.

BACKGROUND: About one-tenth of patients with difficult-to-treat chronic rhinosinusitis with nasal polyps (CRSwNP) have comorbid non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD). Dupilumab, a fully human monoclonal antibody that blocks the shared interleukin (IL)-4/IL-13 receptor component, is an approved add-on treatment in severe CRSwNP. This post hoc analysis evaluated dupilumab efficacy and safety in patients with CRSwNP with/without NSAID-ERD. METHODS: Data were pooled from the phase 3 SINUS-24 and SINUS-52 studies in adults with uncontrolled severe CRSwNP who received dupilumab 300 mg or placebo every 2 weeks. CRSwNP, nasal airflow, lung function, and asthma control outcomes at Week 24 were evaluated, and treatment-subgroup interactions were assessed for patients with and without NSAID-ERD. RESULTS: Of 724 patients, 204 (28.2%) had a diagnosis of NSAID-ERD. At Week 24, least squares mean treatment differences demonstrated significant improvements in nasal polyp score, nasal congestion (NC), Lund-Mackay computed tomography, 22-item Sinonasal Outcome Test (SNOT-22), Total Symptom Score (TSS), rhinosinusitis severity visual analog scale, peak nasal inspiratory flow (PNIF), six-item Asthma Control Questionnaire score, and improvement in smell with dupilumab versus placebo (all p < .0001) in patients with NSAID-ERD. Treatment comparisons demonstrated significantly greater improvements with dupilumab in patients with versus without NSAID-ERD for NC (p = .0044), SNOT-22 (p = .0313), TSS (p = .0425), and PNIF (p = .0123). CONCLUSIONS: In patients with uncontrolled severe CRSwNP, dupilumab significantly improved objective measures and patient-reported symptoms to a greater extent in the presence of comorbid NSAID-ERD than without. Dupilumab was well tolerated in patients with/without NSAID-ERD.

BACKGROUND: Dupilumab is a fully human anti-interleukin-4 receptor α monoclonal antibody that blocks both interleukin-4 and interleukin-13 signaling. Its effectiveness in reducing oral glucocorticoid use in patients with severe asthma while maintaining asthma control is unknown. METHODS: We randomly assigned 210 patients with oral glucocorticoid-treated asthma to receive add-on dupilumab (at a dose of 300 mg) or placebo every 2 weeks for 24 weeks. After a glucocorticoid dose-adjustment period before randomization, glucocorticoid doses were adjusted in a downward trend from week 4 to week 20 and then maintained at a stable dose for 4 weeks. The primary end point was the percentage reduction in the glucocorticoid dose at week 24. Key secondary end points were the proportion of patients at week 24 with a reduction of at least 50% in the glucocorticoid dose and the proportion of patients with a reduction to a glucocorticoid dose of less than 5 mg per day. Severe exacerbation rates and the forced expiratory volume in 1 second (FEV1) before bronchodilator use were also assessed. RESULTS: The percentage change in the glucocorticoid dose was -70.1% in the dupilumab group, as compared with -41.9% in the placebo group (P<0.001); 80% versus 50% of the patients had a dose reduction of at least 50%, 69% versus 33% had a dose reduction to less than 5 mg per day, and 48% versus 25% completely discontinued oral glucocorticoid use. Despite reductions in the glucocorticoid dose, in the overall population, dupilumab treatment resulted in a severe exacerbation rate that was 59% (95% confidence interval [CI], 37 to 74) lower than that in the placebo group and resulted in an FEV1 that was 0.22 liters (95% CI, 0.09 to 0.34) higher. Injection-site reactions were more common with dupilumab than with placebo (9% vs. 4%). Transient blood eosinophilia was observed in more patients in the dupilumab group than in the placebo group (14% vs. 1%). CONCLUSIONS: In patients with glucocorticoid-dependent severe asthma, dupilumab treatment reduced oral glucocorticoid use while decreasing the rate of severe exacerbations and increasing the FEV1. Transient eosinophilia was observed in approximately 1 in 7 dupilumab-treated patients.

BACKGROUND: The phase 3 LIBERTY ASTHMA QUEST study (ClinicalTrials.gov: NCT02414854) in patients with uncontrolled, moderate-to-severe asthma has demonstrated the efficacy and safety of dupilumab 200 and 300â mg every 2â weeks versus placebo. This post hoc analysis assessed the effect of dupilumab on efficacy outcomes and asthma control across a range of historical exacerbation rates in patients with type 2-high asthma. METHODS: Annualised severe exacerbation rates over the 52-week treatment period, pre-bronchodilator forced expiratory volume in 1â s (FEV1) at weeks 12 and 52, and the five-item Asthma Control Questionnaire (ACQ-5) score at weeks 24 and 52 were assessed in patients with ≥1, ≥2 or ≥3 exacerbations in the previous year. Subgroups were stratified by baseline blood eosinophils ≥150 or ≥300â cells·µL-1 or baseline exhaled nitric oxide fraction ≥25â ppb and baseline inhaled corticosteroid (ICS) dose. RESULTS: Across all type 2-high subgroups, dupilumab versus placebo significantly reduced severe exacerbations by 54-90%, with greater improvements in patients with more exacerbations prior to study initiation. Similarly, improvements in FEV1 (least squares (LS) mean difference versus placebo: ≥1 exacerbations, 0.15-0.25â L; ≥2 exacerbations, 0.12-0.32â L; ≥3 exacerbations, 0.09-0.38â L; majority p<0.05) and ACQ-5 score (LS mean difference range: ≥1 exacerbations, -0.30 to -0.57; ≥2 exacerbations, -0.29 to -0.56; ≥3 exacerbations, -0.43 to -0.61; all p<0.05) were observed, irrespective of prior exacerbation history, across all subgroups. CONCLUSIONS: Dupilumab significantly reduced severe exacerbations and improved FEV1 and asthma control in patients with elevated type 2 biomarkers irrespective of exacerbation history and baseline ICS dose.

BACKGROUND: Although there are many asymptomatic patients, one of the problems of COVID-19 is early recognition of the disease. COVID-19 symptoms are polymorphic and may include upper respiratory symptoms. However, COVID-19 symptoms may be mistaken with the common cold or allergic rhinitis. An ARIA-EAACI study group attempted to differentiate upper respiratory symptoms between the three diseases. METHODS: A modified Delphi process was used. The ARIA members who were seeing COVID-19 patients were asked to fill in a questionnaire on the upper airway symptoms of COVID-19, common cold and allergic rhinitis. RESULTS: Among the 192 ARIA members who were invited to respond to the questionnaire, 89 responded and 87 questionnaires were analysed. The consensus was then reported. A two-way ANOVA revealed significant differences in the symptom intensity between the three diseases (p < .001). CONCLUSIONS: This modified Delphi approach enabled the differentiation of upper respiratory symptoms between COVID-19, the common cold and allergic rhinitis. An electronic algorithm will be devised using the questionnaire.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) and type 2 asthma share the same inflammatory pathophysiology and are frequent comorbidities. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin 4 and interleukin 13, which are key and central drivers of type 2 inflammation. OBJECTIVE: We report the effect of dupilumab vs placebo on outcome measures of the upper and lower airways and health-related quality of life (HRQoL) in the pooled population of patients with CRSwNP and comorbid asthma from the phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) studies. METHODS: In these randomized, double-blind, placebo-controlled trials, patients received subcutaneous dupilumab 300 mg (n = 438) or placebo (n = 286) every 2 weeks on a background of mometasone furoate nasal spray. Changes from baseline at week 24 in the upper and lower airway outcome measures are reported. RESULTS: Of the 724 patients randomized, 428 (59.1%) had comorbid asthma. In patients with asthma at week 24, dupilumab vs placebo improved the nasal polyp score (-2.04), patient-reported nasal congestion score (-1.04), Lund-Mackay computed tomography scan score (-6.43), peak nasal inspiratory flow (46.15 L/min), and 22-item sinonasal outcome test score (-21.42; all P < .001). The forced expiratory volume in 1 second and 6-item asthma control questionnaire scores were also markedly improved with dupilumab vs placebo. The most common adverse events (nasopharyngitis, headache, injection-site erythema, worsening of nasal polyposis, and asthma) were more frequent with placebo than dupilumab. CONCLUSION: Dupilumab improved upper and lower airway outcome measures and HRQoL in patients with severe CRSwNP and comorbid asthma and was well tolerated.

BACKGROUND: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) generally have a high symptom burden and poor health-related quality of life, often requiring recurring systemic corticosteroid use and repeated sinus surgery. Dupilumab is a fully human monoclonal antibody that inhibits signalling of interleukin (IL)-4 and IL-13, key drivers of type 2 inflammation, and has been approved for use in atopic dermatitis and asthma. In these two studies, we aimed to assess efficacy and safety of dupilumab in patients with CRSwNP despite previous treatment with systemic corticosteroids, surgery, or both. METHODS: LIBERTY NP SINUS-24 and LIBERTY NP SINUS-52 were two multinational, multicentre, randomised, double-blind, placebo-controlled, parallel-group studies assessing dupilumab added to standard of care in adults with severe CRSwNP. SINUS-24 was done in 67 centres in 13 countries, and SINUS-52 was done in 117 centres in 14 countries. Eligible patients were 18 years or older with bilateral CRSwNP and symptoms despite intranasal corticosteroid use, receiving systemic corticosteroids in the preceding 2 years, or having had sinonasal surgery. Patients in SINUS-24 were randomly assigned (1:1) to subcutaneous dupilumab 300 mg or placebo every 2 weeks for 24 weeks. Patients in SINUS-52 were randomly assigned (1:1:1) to dupilumab 300 mg every 2 weeks for 52 weeks, dupilumab every 2 weeks for 24 weeks and then every 4 weeks for the remaining 28 weeks, or placebo every 2 weeks for 52 weeks. All patients were randomly assigned centrally with a permuted block randomisation schedule. Randomisation was stratified by asthma or non-steroidal anti-inflammatory drug-exacerbated respiratory disease status at screening, previous surgery at screening, and country. Patients with or without comorbid asthma were included. Coprimary endpoints were changes from baseline to week 24 in nasal polyp score (NPS), nasal congestion or obstruction, and sinus Lund-Mackay CT scores (a coprimary endpoint in Japan), done in an intention-to-treat population. Safety was assessed in a pooled population of both dupilumab groups in SINUS-52 up to week 24 and the dupilumab group in SINUS-24 and the placebo groups in both studies until week 24. The trials are complete and registered at ClinicalTrials.gov, NCT02912468 and NCT02898454. FINDINGS: Between Dec 5, 2016, and Aug 3, 2017, 276 patients were enrolled in SINUS-24, with 143 in the dupilumab group and 133 in the placebo group receiving at least one study drug dose. Between Nov 28, 2016, and Aug 28, 2017, 448 patients were enrolled in SINUS-52, with 150 receiving at least one dose of dupilumab every 2 weeks, 145 receiving at least one dose of dupilumab every 2 weeks for 24 weeks and every 4 weeks until week 52, and 153 receiving at least one dose of placebo. Dupilumab significantly improved the coprimary endpoints in both studies. At 24 weeks, least squares mean difference in NPS of dupilumab treatment versus placebo was -2·06 (95% CI -2·43 to -1·69; p<0·0001) in SINUS-24 and -1·80 (-2·10 to -1·51; p<0·0001) in SINUS-52; difference in nasal congestion or obstruction score was -0·89 (-1·07 to -0·71; p<0·0001) in SINUS-24 and -0·87 (-1·03 to -0·71; p<0·0001) in SINUS-52; and difference in Lund-Mackay CT scores was -7·44 (-8·35 to -6·53; p<0·0001) in SINUS-24 and -5·13 (-5·80 to -4·46; p<0·0001) in SINUS-52. The most common adverse events (nasopharyngitis, worsening of nasal polyps and asthma, headache, epistaxis, and injection-site erythema) were more frequent with placebo. INTERPRETATION: In adult patients with severe CRSwNP, dupilumab reduced polyp size, sinus opacification, and severity of symptoms and was well tolerated. These results support the benefits of adding dupilumab to daily standard of care for patients with severe CRSwNP who otherwise have few therapeutic options.

BACKGROUND: Comorbid perennial allergic rhinitis (PAR) or year-round aeroallergen sensitivity substantially contributes to disease burden in patients with asthma. Dupilumab blocks the shared receptor for interleukin (IL) 4 and IL-13, key drivers of type 2 inflammation that play important roles in asthma and PAR. In the LIBERTY ASTHMA QUEST trial (NCT02414854), dupilumab reduced severe asthma exacerbations and improved forced expiratory volume in 1 second (FEV1) in patients with uncontrolled, moderate-to-severe asthma, with greater efficacy observed in patients with elevated type 2 inflammatory biomarkers at baseline (blood eosinophils and fractional exhaled nitric oxide). OBJECTIVE: To assess dupilumab efficacy in LIBERTY ASTHMA QUEST patients with comorbid PAR. METHODS: Severe asthma exacerbation rates, FEV1, asthma control (5-item Asthma Control Questionnaire), rhinoconjunctivitis-specific health-related quality of life (Standardized Rhinoconjunctivitis Quality of Life Questionnaire +12 scores), and type 2 inflammatory biomarkers during the 52-week treatment period were assessed. RESULTS: A total of 814 of the 1902 patients (42.8%) had comorbid PAR (defined as an allergic rhinitis history and ≥1 perennial aeroallergen specific immunoglobulin E (IgE) level ≥0.35 kU/L at baseline). Dupilumab, 200 and 300 mg every 2 weeks, vs placebo reduced severe exacerbations rates by 32.2% and 34.6% (P < .05 for both) and improved FEV1 at week 12 by 0.14 L and 0.18 L (P < .01 for both); greater efficacy was observed in patients with elevated baseline blood eosinophil counts (≥300 cells/µL) and fractional exhaled nitric oxide. Dupilumab treatment also numerically improved the 5-item Asthma Control Questionnaire and Standardized Rhinoconjunctivitis Quality of Life Questionnaire +12 scores and suppressed type 2 inflammatory biomarkers. CONCLUSION: Dupilumab improved key asthma-related outcomes, asthma control, and rhinoconjunctivitis-specific health-related quality of life while suppressing type 2 inflammatory biomarkers and perennial allergen-specific IgE in patients with moderate-to-severe asthma and comorbid PAR, highlighting its dual inhibitory effects on IL-4 and IL-13 and its role in managing asthma and PAR.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory condition of the nasal and paranasal tissues, characterized by the presence of bilateral nasal polyps. While etiology and pathogenetic mechanisms are heterogeneous and complex, in most patients, disease is mediated predominantly through type 2 inflammatory processes. Clinical management is challenging, and a multidisciplinary approach is preferred. Principal treatment approaches are the use of local/systemic corticosteroids and sinonasal surgery, although outcomes can be unsatisfactory. Recent availability of biological therapies targeting underlying inflammatory processes can offer effective treatment options in uncontrolled disease. Specialist guidelines greatly assist clinical decision-making, although as these are chiefly written from a global/international perspective, they may not wholly accommodate disease patterns and clinical practice at a regional level. An expert panel of specialists from Latin America was convened to develop regional guidance on the management of CRSwNP through a consensus approach. The present article presents the chief observations and recommendations which can provide guidance for clinicians in the Latin American region.
RESUMO
CLINICAL IMPLICATIONS: Dupilumab, a biological therapy that blocks the shared receptor component for interleukins-4/13, reduced exacerbations and improved lung function in children with uncontrolled moderate-to-severe type 2 asthma independent of most baseline patient and asthma characteristics.
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.
