Abstract
BACKGROUND 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 and -13, which are key and central drivers of type 2 inflammation. Phase 3 LIBERTY ASTHMA VENTURE (NCT02528214) and LIBERTY ASTHMA 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 to 96 weeks (TRAVERSE) in patients with oral corticosteroid (OCS)-dependent severe asthma. OBJECTIVE To assess dupilumab's impact on Asthma QoL Questionnaire (AQLQ) items related to breathing symptoms, sleep, and activity limitation, and on OCS reduction. METHODS The proportion of patients with AQLQ scores of 6 or 7 for breathing symptoms-, sleeping-, and activity-related items in VENTURE and TRAVERSE, together with OCS dose reductions in VENTURE. RESULTS In VENTURE, significantly greater proportions of dupilumab- vs placebo-treated patients achieved scores of 6 or 7 by week 24 in breathing symptoms-related (42.7%-60.2% vs 22.4%-39.3%), sleeping-related (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-treated vs 65% and 41% of placebo-treated patients with AQLQ scores of 6 or 7 in breathing symptoms-, sleeping-, and activity-related items achieved greater than or equal to 50% dose reduction and eliminated OCS at week 24, respectively. CONCLUSION In patients with severe OCS-dependent asthma, dupilumab improved QoL related to breathing symptoms, sleep, and activity limitation, and reduced OCS use.

Health-Related Quality of Life Impairment Among Patients with Severe Chronic Rhinosinusitis with Nasal Polyps in the SINUS-24 Trial. J Asthma Allergy 2023; 16:323-332.

Abstract
Purpose Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2 inflammatory disease with a high symptom burden. 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.

Dupilumab Efficacy in Patients With Uncontrolled or Oral Corticosteroid-Dependent Allergic and Nonallergic Asthma. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:873-884.e11. [PMID: 36572184 DOI: 10.1016/j.jaip.2022.11.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 11/21/2022] [Accepted: 11/29/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Type 2 cytokines 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 exacerbation rates (AER), improved forced expiratory volume in 1 second (FEV1), and was generally well tolerated in patients with uncontrolled, moderate-to-severe, or oral corticosteroid (OCS)-dependent severe asthma. OBJECTIVE The post hoc assessment of dupilumab efficacy versus placebo in P2B and VENTURE in patients stratified by allergic status. METHODS Allergic asthma was defined as total serum IgE ≥30 IU/mL and ≥1 perennial aeroallergen-specific IgE ≥0.35 kU/L at baseline. AER, prebronchodilator (BD) FEV1, FEV1/forced vital capacity (FVC) ratio, asthma control (5-item Asthma Control Questionnaire), health-related quality of life (HRQoL; Asthma Quality of Life Questionnaire), type 2 biomarkers, specific IgE, and OCS reduction (VENTURE only) were assessed. RESULTS In patients with allergic asthma, dupilumab (P2B: pooled 200/300 mg; VENTURE: 300 mg) every 2 weeks versus placebo reduced AER (P2B: -60%, P < .01; VENTURE: -72%, P < .001), and, in P2B, increased pre-BD FEV1 (P < .01) and FEV1/FVC (P < .05). In both studies, dupilumab significantly improved asthma control and HRQoL and reduced most type 2 biomarkers. Dupilumab significantly reduced OCS use in VENTURE. Similar benefits were observed in patients without evidence of allergic asthma. CONCLUSIONS Dupilumab significantly reduced AER and improved lung function, asthma control, and HRQoL in patients with or without evidence of allergic asthma.

Long-term effect of dupilumab on prevention of lung function decline in patients with uncontrolled moderate-to-severe asthma: ATLAS trial design. ERJ Open Res 2023; 9:00417-2022. [PMID: 36891077 PMCID: PMC9986762 DOI: 10.1183/23120541.00417-2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Accepted: 10/20/2022] [Indexed: 11/18/2022] Open
Abstract
Background Many patients with asthma experience loss of lung function over time, and in certain patients this can lead to progressive obstructive patterns similar to COPD. Patients with severe asthma may experience accelerated lung function decline (LFD). However, characteristics and risk factors for LFD in asthma have not been well described. Dupilumab may prevent or slow the rate of LFD in patients with uncontrolled, moderate-to-severe asthma. ATLAS trial is designed to evaluate the role of dupilumab in preventing/slowing LFD over a period of 3 years versus standard-of-care therapy. Methods ATLAS (clinicaltrials.gov identifier NCT05097287) is a randomised, double-blind, placebo-controlled, multicentre study that will include adult patients with uncontrolled moderate-to-severe asthma. ∼1828 patients will be randomised (2:1) to dupilumab 300 mg or placebo in combination with maintenance therapy every 2 weeks for 3 years. The primary objective is to assess the effect of dupilumab on preventing or slowing LFD by year 1 in the exhaled nitric oxide fraction (F eNO) population (patients with F eNO ≥35 ppb). The effect of dupilumab in slowing the rate of LFD by year 2 and year 3 in both F eNO and total populations, exacerbations, asthma control, quality of life, biomarker changes and utility of F eNO as a biomarker of LFD will also be evaluated. Discussion ATLAS is the first trial assessing the effect of a biologic on LFD, designed to establish the role of dupilumab in prevention of long-term loss of lung function and its potential effect on disease modification, which may provide unique insights into asthma pathophysiology, including predictive and prognostic factors of LFD.

Abstract
BACKGROUND 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. OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSION 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.

Abstract
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.

Abstract
BACKGROUND Severe asthma exacerbations increase the risk of accelerated lung function decline. This analysis examined the effect of dupilumab on forced expiratory volume in 1 s (FEV1 ) in patients with moderate-to-severe asthma and elevated type 2 biomarkers from phase 3 LIBERTY ASTHMA QUEST (NCT02414854). METHODS Changes from baseline in pre- and post-bronchodilator (BD) FEV1 and 5-item Asthma Control Questionnaire (ACQ-5) scores were assessed in patients with elevated type 2 biomarkers at baseline (type 2-150/25: eosinophils ≥150 cells/μl and/or fractional exhaled nitric oxide [FeNO] ≥25 ppb; type 2-300/25: eosinophils ≥300 cells/μl and/or FeNO ≥25 ppb), stratified as exacerbators (≥1 severe exacerbation during the study) or non-exacerbators. RESULTS In exacerbators and non-exacerbators, dupilumab increased pre-BD FEV1 by Week 2 vs placebo; differences were maintained to Week 52 (type 2-150/25: LS mean difference (LSMD) vs placebo: 0.17 L (95% CI: 0.10-0.24) and 0.17 L (0.12-0.23); type 2-300/25: 0.22 L (0.13-0.30) and 0.21 L (0.15-0.28)), in exacerbators and non-exacerbators, respectively (p < .0001). Similar trends were seen for post-BD FEV1 . Dupilumab vs placebo also showed significantly greater improvements in post-BD FEV1 0-42 days after first severe exacerbation in type 2-150/25 (LSMD vs placebo: 0.13 L [0.06-0.20]; p = .006) and type 2-300/25 (0.14 L [0.06-0.22]; p = .001) patients. ACQ-5 improvements were greater with dupilumab vs placebo in both groups. CONCLUSION Dupilumab treatment led to improvements in lung function independent of exacerbations and appeared to reduce the impact of exacerbations on lung function in patients who experienced a severe exacerbation during the study.

Abstract
BACKGROUND Safety and efficacy data for dupilumab beyond 1 year are lacking for patients from Japan with moderate-to-severe asthma. METHODS 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 (FEV1), asthma control, quality of life, and blood eosinophil levels. Anti-drug antibodies (ADA) were evaluated. We report results in 160 (7.8% of exposed population) patients recruited from Japanese centers with non-oral corticosteroid (OCS)-dependent asthma rolled over from two parent studies, and in subgroups with a type 2 inflammatory phenotype. RESULTS TEAEs 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 FEV1. Rapid, sustained improvements were observed in dupilumab-treated patients who previously received placebo in a parent study, while further improvements in exacerbation rates, asthma control, and asthma-related quality of life were observed in those continuing dupilumab. Blood eosinophil levels decreased progressively while on treatment. Treatment-emergent ADA responses were highest in patients who had previously received placebo. Efficacy results were consistent in patients with a type 2 phenotype. CONCLUSIONS Long-term dupilumab treatment was well tolerated and efficacious in patients with non-OCS-dependent, moderate-to-severe asthma recruited from Japan.

Abstract
Purpose Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4/-13, key and central drivers of type 2 (T2) inflammation in multiple diseases. 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.

Abstract
BACKGROUND 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. OBJECTIVE To assess dupilumab efficacy in patients with a type 2 phenotype in the presence or absence of allergic asthma phenotype. METHODS 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 FEV1 were evaluated in patients with allergic and nonallergic phenotype with baseline blood eosinophils greater than or equal to 150 cells/μL and/or Feno greater than or equal to 20 parts per billion. RESULTS Of 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 FEV1 in patients with elevated type 2 biomarkers, irrespective of whether they showed evidence of an allergic asthma phenotype. CONCLUSIONS In 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.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2 inflammatory disease of the nasal and paranasal sinuses. Dupilumab is a monoclonal antibody that blocks the shared receptor component for interleukin-4 and interleukin—13, which are key and central drivers of type 2 inflammation. In clinical trials, dupilumab significantly improved objective and patient-reported measures of CRSwNPversusplacebo and was well tolerated. Dupilumab is approved in the EU, USA, and Japan as add-on maintenance treatment for adults with inadequately controlled CRSwNP. There exists an important evidence gap between efficacy and effectiveness data for dupilumab in severe CRSwNP. In order to bridge this gap, the AROMA prospective global registry (NCT04959448) was established. AROMA will collect long-term data on the utilisation, effectiveness and safety of dupilumab for CRSwNP treatment in real-world clinical practice. AROMA will enrol approximately 1000 adults starting dupilumab for severe CRSwNP across 120 global sites. Baseline data will include patient demographics, medical/surgical history and presence of type 2 comorbidities. Effectiveness outcome assessments will include objective measures of CRSwNP assessed as part of routine clinical care and various patient-reported questionnaires. Treatment patterns, concomitant medications and long-term safety will also be recorded. Results from AROMA, the first prospective, real-world, global registry to characterise patients with severe CRSwNP starting dupilumab, will provide evidence on the real impact of dupilumab in patients with CRSwNP and complement the data from the randomised clinical trials. The registry will also provide evidence on disease progression in patients with CRSwNP including those with co-existing diseases.

Effect of Dupilumab on Blood Eosinophil Counts in Patients With Asthma, Chronic Rhinosinusitis With Nasal Polyps, Atopic Dermatitis, or Eosinophilic Esophagitis. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2695-2709.

Abstract
BACKGROUND Transient increases in blood eosinophil counts have been observed in dupilumab clinical trials. OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
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 300mg 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 0.15L (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.

Abstract
BACKGROUND Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4/-13, key and central drivers of type 2 inflammation in multiple diseases. In the phase 3 LIBERTY ASTHMA VENTURE (VENTURE) study (NCT02528214), dupilumab versus placebo reduced oral corticosteroid (OCS) dose and improved clinical outcomes in patients with OCS-dependent severe asthma. Dupilumab efficacy in patients with varying disease burden (defined by baseline OCS dose) has not been assessed. OBJECTIVE This post hoc analysis of VENTURE evaluated dupilumab efficacy across subgroups defined by baseline OCS dose. METHODS The OCS dose, proportion no longer needing OCS at week 24, annualized severe exacerbation rate, and least squares mean change from baseline in pre- and post-bronchodilator forced expiratory volume in 1 second at week 24 were evaluated in VENTURE patients with OCS-dependent severe asthma receiving dupilumab 300 mg every 2 weeks versus placebo, categorized by a baseline OCS dose of less than 10 mg/d or 10 or more mg/d. RESULTS Dupilumab reduced daily OCS dose from baseline at week 24 in both dose groups. In dupilumab-/placebo-treated patients with a baseline OCS dose of less than 10 mg/d and 10 or more mg/d, 72%/42% and 37%/23% stopped OCS by week 24 (P < .01/P < .05), respectively. Dupilumab significantly reduced the annualized severe exacerbation rate by 71% and 48% (P < .01/P < .05). At week 24, dupilumab improved pre- and post-bronchodilator forced expiratory volume in 1 second in patients in both dose groups. CONCLUSIONS In patients with OCS-dependent severe asthma receiving lower or higher baseline OCS doses, dupilumab significantly reduced the OCS dose and improved the likelihood of no longer requiring OCS while also reducing exacerbations and improving lung function.

Abstract
Patients with asthma frequently have comorbid chronic rhinosinusitis (CRS) with or without nasal polyps, increasing disease burden and complicating treatment. 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.

Abstract
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).

Abstract
Uncontrolled, moderate-to-severe asthma in patients with high baseline blood eosinophils (≥500 cells·µL−1) can be difficult to treat [1]. Global Initiative for Asthma guidelines recommend biologics as add-on therapy for patients with severe type 2 inflammatory asthma that remains uncontrolled despite treatment with high-dose inhaled corticosteroids [2]. Surrogate markers of type 2 inflammation, such as elevated levels of blood or sputum eosinophils and fractional exhaled nitric oxide (FeNO) can be used to identify patients with a type 2 signature who might be eligible for such treatment [1–3]. Several biologics are now available that target different molecules in type 2 inflammatory pathways, notably IgE and type 2 cytokines [1–3]. One of these, dupilumab, is a fully human VelocImmune-derived [4, 5] monoclonal antibody that blocks the shared receptor component for interleukin-4 and -13, cytokines that are key and central drivers of type 2 inflammation in multiple diseases, thus inhibiting their signalling [6, 7]. Dupilumab is well tolerated and improves clinical outcomes in patients with asthma and high eosinophils (≥500 cells·µL−1). Improvements in clinical outcomes correlate with eosinophil counts, demonstrating dupilumab efficacy in those with high eosinophils.https://bit.ly/3Jxvicb

Abstract
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 <.0001; 95% CI 0.51-0.75). Reported upper and lower respiratory tract infection events were numerically or significantly lower in dupilumab-treated patients in both conditions, as were the number of patients experiencing investigator-reported infections. Significantly less systemic anti-infective medication use occurred in dupilumab versus placebo in asthma (24% lower; P < .0001; 95% CI 0.70-0.83) and CRSwNP patients (49% lower; P < .0001; 95% CI 0.43-0.61), and significantly fewer dupilumab-treated patients used anti-infective medications. When examined by season and month, the data indicated that investigator-reported respiratory infections and anti-infective medication use were less frequent in dupilumab- versus placebo-treated patients throughout the calendar year. CONCLUSIONS Dupilumab treatment was associated with a reduced incidence of investigator-reported respiratory infections in patients with moderate-to-severe asthma or severe CRSwNP. Further studies are required to determine the mechanism behind this reduction.

Preclinical and clinical experience with dupilumab on the correlates of live attenuated vaccines. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. GLOBAL 2022; 1:9-15.

Abstract
Background The safety and tolerability of live attenuated vaccines in patients administered dupilumab for moderate-to-severe asthma have not been previously evaluated. During the LIBERTY ASTHMA TRAVERSE open-label extension study (ClinicalTrials.gov identifier NCT02134028), a yellow fever outbreak in Brazil required administration of a live attenuated vaccine to at-risk individuals. Objective Our aim was to evaluate immune response to a live attenuated vaccine in the context of IL-4 receptor blockade (REGN1103, a dupilumab surrogate) in mice and in dupilumab-treated patients with moderate-to-severe asthma who participated in TRAVERSE. Methods In the preclinical study, mice were coadministered REGN1103/isotype control and live attenuated influenza vaccine/control, followed by influenza virus challenge. During TRAVERSE, 37 patients discontinued dupilumab treatment and were administered 17D live attenuated yellow fever vaccine (YFV). Safety and tolerability data, dupilumab serum concentrations, and plaque reduction neutralization titers before and after vaccination were collected. Results In the preclinical study, there was no impact of REGN1103 on vaccine efficacy in mice. In TRAVERSE, all 37 patients who received YFV achieved seroprotection despite most having therapeutic levels of dupilumab, with the magnitude of response appearing unrelated to prevaccination dupilumab concentrations. No instances of vaccine-related adverse events or vaccine hypersensitivity were reported in 36 patients; 1 patient reported nonserious body ache, malaise, and dizziness 7 days after vaccination but recovered fully. Conclusion The preclinical model suggested that dupilumab does not affect the efficacy of live attenuated influenza vaccine. The live attenuated YFV did not raise safety concerns and appeared to be well tolerated in patients with asthma who recently discontinued dupilumab treatment, and dupilumab concentrations had no apparent impact on immunologic response to the vaccine.
