Perceptions on Home-Administration of Biologics in the Context of Severe Asthma: An International Qualitative Study. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2312-2323.e2. [PMID: 35487370 DOI: 10.1016/j.jaip.2022.04.015] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 04/05/2022] [Accepted: 04/11/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Biologics are an effective therapy for severe asthma. Home administration of biologics by patients is likely to facilitate their accessibility. Yet little is known about patients' and health care providers' (HCPs) perceptions regarding home administration of biologics. OBJECTIVE The aim of this study is to create more insight into the perceptions and experiences of patients and HCPs regarding home administration of biologics in the context of the treatment of severe asthma. METHODS A qualitative international study was performed in the Netherlands, United States, Australia, and United Kingdom. In each country, 2 focus groups were held with potential/recent and long-term users of biologics at home. Prior to the focus groups, patients were prompted with themes on online forums. For triangulation purposes, interviews were held with HCPs to discuss salient findings from forums and focus groups. Data were analyzed with qualitative content analysis. RESULTS In total, 75 patients participated in the forums, of which 40 participated in the focus groups. Furthermore, 12 HCPs were interviewed. The following overarching themes were identified: living with severe asthma; practical aspects of using biologics; the role of HCPs regarding biologics; social support from family, friends, and others; effectiveness of biologics and other treatments; side effects of biologics. CONCLUSIONS This study showed that, for those using biologics for severe asthma, the benefits of home administration of biologics usually outweigh inconvenience and side effects. Guided practice, accessible support contact, and monitoring including social support should be central in the transition from hospital to home administration of asthma biologics.

Dupilumab Efficacy in Steroid-Dependent Severe Asthma by Baseline Oral Corticosteroid Dose. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:1835-1843. [PMID: 35398549 DOI: 10.1016/j.jaip.2022.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 02/22/2022] [Accepted: 03/07/2022] [Indexed: 06/14/2023]
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
Asthma is one of the most common noncommunicable diseases; in the majority of patients it is well controlled with inhaled bronchodilators and inhaled corticosteroids, but the management of severe asthma has been a significant challenge historically. The introduction of novel biologic drugs in the past few decades has revolutionised the field, presenting physicians with a variety of biologic drugs with different mechanisms for the treatment of severe asthma.It is of crucial importance to evaluate the effectiveness of these drugs by following their "real-life" effectiveness rather than relying solely on their efficacy, established in carefully designed clinical trials, which therefore do not necessarily match the profile of the real-life patient. Understanding the actual effectiveness of the specific drugs in real-life patients is a crucial part of tailoring the right drugs to the right patients. Registries serve as an important tool in obtaining real-life evidence, since they are in effect observational studies, following the entire patient population.

Abstract
Background Tezepelumab is a human monoclonal antibody that blocks activity of thymic stromal lymphopoietin (TSLP). In the phase IIb PATHWAY study (NCT02054130), tezepelumab significantly reduced annualized asthma exacerbation rates (AAERs) versus placebo in adults with severe, uncontrolled asthma. We evaluated the effects of tezepelumab in reducing type 2 (T2) inflammatory biomarker levels in the PATHWAY population, and the relationship between baseline T2 biomarker levels and AAER. Methods Adults with severe, uncontrolled asthma (n = 550) were randomized to tezepelumab (70 mg or 210 mg every 4 weeks, or 280 mg every 2 weeks) or placebo for 52 weeks. Blood eosinophil count, fractional exhaled nitric oxide (FeNO), and serum total immunoglobulin (Ig)E, interleukin (IL)‐5, IL‐13, periostin, thymus and activation‐regulated chemokine (TARC), and TSLP were measured at baseline and over 52 weeks. AAERs were analyzed by baseline threshold (high/low) biomarker levels. Results Positive correlations were observed between T2 inflammatory biomarkers (blood eosinophil count, FeNO, IL‐5, IL‐13 and periostin) at baseline. At Week 52, treatment with tezepelumab 210 mg reduced all biomarker levels measured from baseline versus placebo. Exacerbations were reduced by 55–83% in the pooled tezepelumab cohort versus placebo, irrespective of baseline blood eosinophil count, FeNO, or serum total IgE, IL‐5, IL‐13, periostin, TARC, or TSLP, when these biomarkers were assessed individually. Conclusion At baseline, positive correlations between specific T2 inflammatory biomarkers were observed. Tezepelumab reduced multiple T2 inflammatory biomarkers, which indicates decreased airway inflammation, and reduced exacerbations irrespective of baseline T2 biomarker profiles in patients with severe asthma.

Abstract
Eosinophil-associated diseases (EADs) are a range of heterogeneous conditions in which eosinophils are believed to play a critical pathological role. EADs include common illnesses such as eosinophilic asthma and chronic rhinosinusitis and rare conditions such as hypereosinophilic syndromes (HES) and eosinophilic gastrointestinal disorders (EGIDs). EADs are associated with substantial burdens for the patient, including chronic, debilitating symptoms, increased financial burden, decreased health-related quality of life, and the need for repeated visits to multiple different healthcare professionals (HCPs), emergency departments, and/or hospitals. Poor EAD recognition by HCPs often contributes to delayed diagnoses, which further delays patient access to appropriate care and effective treatments, contributing to poor health outcomes. The objective of this charter is to outline key patient rights and expectations with respect to the management of their condition(s) and to set forth an ambitious action plan to improve health outcomes for patients with EADs: (1) people with EADs, their caretakers, HCPs, and the public must have greater awareness and education about EADs; (2) people with EADs must receive a timely, accurate diagnosis; (3) all people with EADs must have access to an appropriate multidisciplinary team, when necessary; and (4) people with EADs must have access to safe and effective treatment options without unnecessary regulatory delays. The principles described in this charter demonstrate the core elements of quality care that people with EADs must receive, and they represent clear steps by which to reduce patient and caregiver burden and improve patient outcomes. We urge HCPs, healthcare systems, and policymakers worldwide to swiftly adopt these principles to ensure patients with EADs have an accurate diagnosis in a timely manner and access to high-level care and treatment in an appropriate setting.

Clinical Remission in Severe Asthma: A Pooled Post Hoc Analysis of the Patient Journey with Benralizumab. Adv Ther 2022; 39:2065-2084. [PMID: 35287231 PMCID: PMC9056458 DOI: 10.1007/s12325-022-02098-1] [Citation(s) in RCA: 41] [Impact Index Per Article: 20.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 02/18/2022] [Indexed: 12/29/2022]
Abstract
Introduction Consensus definitions for clinical remission and super-response were recently established for severe asthma. Benralizumab is an interleukin-5 (IL-5) receptor α-directed monoclonal antibody for severe, uncontrolled asthma; efficacy and safety were demonstrated in previous pivotal phase 3 trials (SIROCCO, CALIMA, ZONDA). This analysis applied a composite remission definition to characterize individual responses to benralizumab after 6 and 12 months. Methods In previous phase 3 studies, eligible patients were those with severe, uncontrolled asthma receiving medium- or high-dosage inhaled corticosteroids plus long-acting β2-agonists. This post hoc analysis included patients randomized to the approved benralizumab dose and not receiving oral corticosteroids (OCS) at baseline (SIROCCO/CALIMA) or OCS ≤ 12.5 mg per day (ZONDA). Individual remission components were zero exacerbations; zero OCS use; Asthma Control Questionnaire-6 (ACQ-6) score < 1.5 or ≤ 0.75; and pre-bronchodilator forced expiratory volume in 1 s (FEV1) increase ≥ 100 mL; clinical remission incorporated zero exacerbations, zero OCS use, ACQ-6 score ≤ 0.75, and pre-bronchodilator FEV1 increase ≥ 100 mL after 6 or 12 months. Results Overall, 609 patients (N = 301 and N = 308) and 586 patients (N = 293 and N = 293) receiving benralizumab in SIROCCO and CALIMA were included at 6 and 12 months, respectively; 40 ZONDA patients were included after 6 months. In SIROCCO/CALIMA, similar to 6-month findings, approx. 83% and approx. 49% receiving benralizumab, and 77% and 37% on placebo achieved ≥ 2 and ≥ 3 remission components after 12 months; 14.5% (85/586) on benralizumab and 7.7% (48/620) on placebo achieved clinical remission at 12 months. Among ZONDA patients, 75% and approx. 48% on benralizumab and 35% and 20% on placebo achieved ≥ 2 and ≥ 3 remission components at 6 months, respectively; 22.5% (9/40) on benralizumab and 7.5% on placebo achieved clinical remission. Conclusions This analysis demonstrates clinical remission is achievable by targeting the underlying drivers of inflammation. Precision medicines can help shift treatment paradigms toward treat-to-target, with clinical remission as the ultimate therapeutic goal in severe asthma. Clinical trial registration SIROCCO (NCT01928771); CALIMA (NCT01914757); ZONDA (NCT02075255). Dr. Andrew Menzies-Gow Discusses a Post Hoc Analysis of Clinical Remission in Severe Asthma with Benralizumab
Supplementary Information The online version contains supplementary material available at 10.1007/s12325-022-02098-1. Widely accepted definitions for disease remission are already established for the treatment of rheumatoid arthritis, ulcerative colitis, and cancer, among others. Two separate expert groups recently collaborated to discuss clinical remission/super-response to treatment in patients with severe asthma. Both groups developed separate, yet similar ways to determine whether a patient should be considered “in remission.” In this study, we used the results from three previous trials (SIROCCO, CALIMA, and ZONDA) that were conducted to assess a therapy called benralizumab in patients with severe asthma to identify patients who met some or all of the criteria for disease remission in severe asthma. These criteria included zero asthma exacerbations; zero oral steroid (OCS) use; asthma control score; and improvement in lung function. Across all three trials, about three quarters of the patients achieved two or more remission components and about half achieved three or more remission components after 6 months of treatment; furthermore, these rates were generally similar to the numbers of patients who achieved two or more components and three or more components of remission after 12 months of treatment. Overall, 15–23% of patients achieved clinical remission in 6 months, and approximately 15% achieved remission within 12 months. The results show that biologic therapies like benralizumab help improve the symptoms of severe asthma and allow patients to achieve disease remission.

Abstract
Background: Combining a fraction of exhaled nitric oxide (FeNO) and blood eosinophil count (B-EOS) may be a useful strategy for administration of biologics such as anti-IgE or anti-IL-5 to patients with type 2 inflammatory-predominant severe asthma and is important to be elucidated considering the increasing use of biologics. Methods: This cross-sectional study analyzed the clinical data from 114 adult patients with severe asthma, who were treated at Saitama Medical University Hospital. The eligible patients were stratified into four subgroups defined by thresholds of FeNO and blood eosinophil (B-EOS) counts to detect sputum eosinophilia, using the receiver operating characteristic curve analysis. A total of 75 patients with optimal samples were stratified into four subtypes defined by thresholds of sputum eosinophilia and neutrophilia. Clinical characteristics, pattern of biologics, and distribution of sputum subtypes were analyzed in the stratified subclasses according to the FeNO and B-EOS thresholds. The asthma exacerbation (AE)-free time of the FeNO/B-EOS subgroups and any biologics treatment including anti-IgE or anti-IL-5 use were examined using the Kaplan–Meier method. The hazard ratios (HRs) for AE-free time were examined using the Cox proportional hazard model. Results: The optimal cutoff values for prediction of sputum eosinophilia were defined as ≥2.7% wherein for FeNO as ≥27 ppb and B-EOS as ≥265/µL were considered. The high-FeNO subgroups showed significant high total IgE, compared with the low FeNO. The high-FeNO/high-B-EOS and the high-FeNO/low-B-EOS subgroups showed the largest prevalence of mepolizumab and benralizumab use among the other FeNO/B-EOS, respectively. The high-FeNO/low-B-EOS showed the largest frequency of AEs, high HR, and the shortest AE-free time, among the other FeNO/B-EOS. The sputum eosinophil-predominant subtype was the great majority in the high FeNO/high B-EOS. A diverse distribution of sputum leukocyte-predominant subtype was observed in the other FeNO/B-EOS. The subsequent AE-free time and its HR were comparable among the biologics use groups. Conclusion: The strategy of classifying severe asthma based on the combination of FeNO and B-EOS proposes particular refractory type 2 severe asthma and underlying airway inflammation as a feasible trait for optimal biologics use.

Abstract
Asthma is a heterogeneous chronic inflammatory airway disease that imposes a great burden on public health worldwide. In the past two years, fundamental changes have been addressed in the Global Initiative for Asthma (GINA) recommendations focusing mainly on the management of mild and severe asthma. The use of as-needed treatment containing inhaled corticosteroids plus fast-acting bronchodilators (either short or long-acting formoterol) in mild asthma has dominated the field, and both randomized and real-world studies favor such an approach and associate it with fewer exacerbations and good asthma control. At the same time, the effort to diminish the use of oral steroids (OCS) as maintenance treatment in severe asthma was substantially accomplished with the initiation of treatment with biologics. Still, these options are available at the moment only for severe asthmatics with a T2-high endotype, and relevant studies on biologics have yielded, as a primary outcome, the reduction or even cessation of OCS. Accordingly, OCS should be considered as a temporary option, mainly for the treatment of asthma exacerbations, and as a maintenance treatment only for a minority of patients with severe asthma, after ensuring good inhaler technique, modification of all possible contributory factors and comorbidities, and optimized pharmacotherapy using all other add-on treatments including biologics in the armamentarium of anti-asthma medication.

Abstract
The fraction of exhaled nitric oxide (FENO) is a biomarker for type 2 asthma, reflecting the degree of local pulmonary inflammation linked to immune pathways, including interleukin (IL)-13 [1]. In clinical practice, FENO is a reliable marker for inhaled corticosteroid (ICS) responsiveness [2] and the efficacy of biological therapies, such as those targeting IL-4/IL-13 pathways [3, 4], as well as the detection of steroid nonadherence or resistance in severe asthma [2]. The prospective Severe Asthma Registry of the German Asthma Net (GAN) enrols patients with severe asthma for in-depth assessment of phenotypes, underlying mechanisms and therapeutic strategies; GAN has been approved by respective ethics committees, with all included patients having signed informed consent [5]. Prior studies of FENO either included patients with asthma of any severity [6] or did not involve a comprehensive analysis in a large cohort [7]. We therefore used cross-sectional data from GAN to determine the correlation of FENO with epidemiological, laboratory, clinical, lung function, or quality of life parameters and the need for oral corticosteroid (OCS) maintenance therapy in a carefully selected severe asthma cohort to better characterise the severe asthma subtype with high FENO values. In a severe asthma cohort of 1007 patients, high FENO was associated with chronic rhinosinusitis/polyps, later asthma onset, poor lung function and asthma control, low quality of life, frequent exacerbations and the need for maintenance OCS. #GANregistry https://bit.ly/3sNrtIQ

Abstract
Rhinovirus infections can cause wheezing illnesses in all age groups. In preschool children, rhinovirus infections frequently initiate acute wheezing illnesses. Children who wheeze with rhinoviruses are at increased risk to go on to develop asthma. Once asthma is established, rhinovirus infections are potent triggers for acute airway obstruction and exacerbations in children and adults. Paradoxically, for most individuals, rhinovirus infections commonly cause cold symptoms with little or no involvement of the lower airways. This paradox has led investigators to identify specific risk factors and mechanisms for rhinovirus wheezing, and this review will outline progress in 3 main areas. First, the 3 species of rhinoviruses have different patterns of infection and virulence. Second, personal factors such as lung function and immunity influence lower respiratory outcomes of rhinovirus infection. The mucosal immune response is critical, and the quality of the interferon response and allergic inflammation interacts to determine the risk for rhinovirus wheezing. Finally, rhinovirus infections can promote pathogen-dominated airway microbiota that increase the risk for wheezing. Although specific antivirals for rhinovirus are still not available, identifying risk factors for wheezing illnesses has provided several other potential targets and strategies for reducing the risk of rhinovirus-induced wheezing and exacerbations of asthma.

Abstract
Asthma is a heterogenous respiratory disease, usually associated with chronic airway inflammation and hyper-responsiveness, which affects an estimated 339 million people worldwide. Severe asthma affects approximately 5-10% of patients with asthma, approximately 17-34 million people globally, more than half of whom have uncontrolled disease. Severe asthma carries a substantial burden of disease, including unpredictable symptoms and potentially life-threatening flare-ups. Furthermore, severe asthma has a substantial burden on health care systems and economies worldwide. In 2018, a group of experts from the clinical community, patient support groups, and professional organisations joined together to develop the Severe Asthma Patient Charter, which set out six principles to define what patients should expect for the management of their severe asthma and what should constitute a basic standard of care. Since the publication of that original Charter in 2018, several important changes have occurred, including an improved understanding of asthma and effective asthma management; several new therapies have become available; and finally, the COVID-19 pandemic has placed a spotlight on respiratory conditions, the workforces that treat them, and the fundamental importance of health care system resilience. With those developments in mind, we, representatives of the academic, clinical, and patient advocacy group communities, have updated the Charter to Improve Patient Care in Severe Asthma with a focus on six principles: (1) I deserve a timely, comprehensive assessment of my asthma and its severity; (2) I deserve a timely, straightforward referral to an appropriate specialist for my asthma when it is not well controlled; (3) I deserve to understand what makes my asthma worse; (4) I deserve access to treatment and care that reduces the impact of asthma on my daily life; (5) I deserve not to be reliant on systemic corticosteroids; (6) I deserve to be involved in decisions about my treatment and care.

Abstract
Purpose Oral corticosteroids (OCS) are commonly used in patients with severe asthma, but they are associated with several adverse events. We estimated the prevalence of patients with OCS-dependent asthma in a large nationwide registry for severe asthma and delineated their clinical characteristics. Methods This cross-sectional study analyzed enrollment data of the patients recruited in the Korean Severe Asthma Registry (KoSAR) from 2010 to 2019. The clinical characteristics of patients were compared according to OCS dependency, which was defined as maintenance OCS treatment lasting at least 6 months during the 12 months prior to enrollment. Results Among the 562 patients with severe asthma, 121 (21.5%) patients were defined as having OCS-dependent asthma. Compared with the OCS-independent group, the OCS-dependent group was older at symptom onset and had a higher prevalence of anxiety, worse lung function, and used more medication than the control group. Despite the higher doses of daily ICS and 6-month cumulative OCS, the OCS-dependent group reported greater consumption of relievers and a higher prevalence of unscheduled emergency room visits and repeated OCS bursts. Although anti-interleukin-5 was more commonly prescribed for patients with OCS-dependent asthma, only a limited proportion of patients with severe asthma received biologics. Conclusions One-fifth of patients with severe asthma had OCS-dependency, which was associated with a greater disease burden compared to those with OCS-independent asthma. Active intervention including initiation of biologics and regular assessment of OCS-induced morbidities is warranted to reduce the use of OCS and its potential adverse effects.

Abstract
BACKGROUND Wheezing in early life is associated with asthma in adulthood; however, the determinants of wheezing trajectories and their associations with asthma and lung function in childhood remain poorly understood. OBJECTIVE In the CHILD Cohort Study, we aimed to identify wheezing trajectories and examine the associations between these trajectories, risk factors, and clinical outcomes at age 5 years. METHODS Wheeze data were collected at 8 time points from 3 months to 5 years of age. We used group-based trajectory models to derive wheeze trajectories among 3154 children. Associations with risk factors and clinical outcomes were analyzed by weighted regression models. RESULTS We identified 4 trajectories: a never/infrequent trajectory, transient wheeze, intermediate-onset (preschool) wheeze, and persistent wheeze. Higher body mass index was a common risk factor for all wheeze trajectories compared with that in the never/infrequent group. The unique predictors for specific wheeze trajectories included male sex, lower respiratory tract infections, and day care attendance for transient wheeze; paternal history of asthma, atopic sensitization, and child genetic risk score of asthma for intermediate wheeze; and maternal asthma for persistent wheeze. Blood eosinophil counts were higher in children with the intermediate wheeze trajectory than in those children with the other trajectories at the ages of 1 and 5 years. All wheeze trajectories were associated with decreased lung function and increased risk of asthma at age 5 years. CONCLUSIONS We identified 4 distinct trajectories in children from 3 months to 5 years of age, reflecting different phenotypes of early childhood wheeze. These trajectories were characterized by different biologic and physiologic traits and risk factors.

Abstract
Advances in the understanding that severe asthma is a complex and heterogeneous disease and in the knowledge of the pathophysiology of asthma, with the identification of different phenotypes and endotypes, have allowed new approaches for the diagnosis and characterization of the disease and have resulted in relevant changes in pharmacological management. In this context, the definition of severe asthma has been established, being differentiated from difficult-to-control asthma. These recommendations address this topic and review advances in phenotyping, use of biomarkers, and new treatments for severe asthma. Emphasis is given to topics regarding personalized management of the patient and selection of biologicals, as well as the importance of evaluating the response to treatment. These recommendations apply to adults and children with severe asthma and are targeted at physicians involved in asthma treatment. A panel of 17 Brazilian pulmonologists was invited to review recent evidence on the diagnosis and management of severe asthma, adapting it to the Brazilian reality. Each of the experts was responsible for reviewing a topic or question relevant to the topic. In a second phase, four experts discussed and structured the texts produced, and, in the last phase, all experts reviewed and approved the present manuscript and its recommendations.

Abstract
INTRODUCTION Fixed-dose long-acting beta2-agonist (LABA)/inhaled corticosteroid (ICS) combinations and add-on therapies as needed are the mainstay for maintenance therapy in asthma. However, more than 40% of patients have an inadequately controlled disease. The development of triple fixed-dose combinations consisting of long-acting muscarinic antagonist (LAMA)/LABA/ICS has paved the way for a new approach to reach therapeutic goals of an optimal control of symptoms and an effective prevention of future exacerbations. AREAS COVERED A search was conducted on PubMed (MEDLINE), using the MeSH terms [asthma] + [indacaterol] + [glycopyrronium] +[mometasone furoate] + [treatment], until October 2021. Original data from clinical trials, prospective and retrospective studies and reviews were selected. Clinical studies with IND/MF/GLY (Enerzair Breezhaler) are summarized, and its place in current asthma therapy is examined. EXPERT OPINION Triple therapy has been shown to be an effective and safe therapeutic option for asthma patients who remain uncontrolled despite ICS/LABA combination. The recently approved single-inhaler indacaterol/glycopyrronium/mometasone fixed dose combination has demonstrated to significantly reduce exacerbations, improve FEV1, symptoms and quality of life compared to ICS/LABA, including, salmeterol/fluticasone combination. Moreover, once-daily dosing may improve adherence.

Abstract
BACKGROUND There are limited published data on the burden of moderate/severe uncontrolled asthma. METHODS We conducted a systematic literature review to better understand the impact of moderate-to-severe asthma in the US, the UK, Germany, France, Italy, Spain, Canada, Japan, and Australia in terms of prevalence, clinical measures, health-related quality of life (HRQoL) and economic burden, for patients whose asthma is uncontrolled despite inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) therapy. RESULTS The prevalence of uncontrolled asthma among patients with moderate/severe disease varied but was as high as 100% in some subgroups. Patients with uncontrolled asthma generally had poor lung function (mean/median pre-bronchodilator forced expiratory volume in 1 second [FEV1]: 1.69-2.45 L; mean/median pre-bronchodilator percent predicted FEV1: 57.2-79.7). There was also a substantial but variable exacerbation burden associated with uncontrolled asthma, with the annualised rate of exacerbations ranging from 1.30 to 7.30 when considering various patient subgroups. Furthermore, the annualised rate of severe exacerbations ranged from 1.66 to 3.60. The HRQoL burden measured using disease-specific and generic instruments consistently demonstrated substantial impairment of HRQoL for those with uncontrolled asthma; Asthma Quality of Life Questionnaire scores ranged from 3.00 to 5.20, whilst EurQol-5 Dimensions index scores ranged from 0.53 to 0.59. Direct, indirect and total costs together with consumption of other healthcare resources associated with managing uncontrolled asthma were also substantial in the population studied; no caregiver burden was identified. CONCLUSIONS Our findings suggest that significant unmet needs exist for patients with uncontrolled asthma despite the availability of ICS/LABA therapy. Novel treatments are needed to help reduce the burden to patients, healthcare systems and society.

Abstract
OBJECTIVE To identify treatment approaches that can be used in the management of patients with asthma who lack significant type 2 inflammation, also called T2 low asthma. DATA SOURCES Recent expert guideline updates on the management of asthma, recent journal articles and review articles, and foundational journal articles are referenced. STUDY SELECTIONS This review cites clinical cohort studies of highly characterized patients with asthma, clinical interventional trials of high impact, mechanistic studies relevant to T2 low asthma, and emerging work in this area. RESULTS T2 low asthma accounts for approximately one-third to one-half of individuals with asthma. Characteristics of participants with T2 low asthma include higher body mass index, cigarette smoking/smoke exposure, relative lack of responsiveness to steroids, less bronchodilator reversibility, and often the presence of neutrophilic inflammation. Multiple available interventions target these characteristics, including standard inhalers, azithromycin, and lifestyle interventions of weight loss and smoking cessation. CONCLUSION Treatment of T2 low asthma should involve currently available approaches and will benefit from improved definition and understanding of disease pathobiology.

Abstract
INTRODUCTION Data on severe asthma in France are scarce. The aim of this study was to evaluate adherence to asthma treatments and its determinants in a population of severe asthmatics. METHODS From May 2016 to June 2017, the French Collège des Pneumologues des Hôpitaux Généraux organized a large-scale prospective, cross-sectional, multicenter study on this topic; 1502 patients with severe asthma were included. RESULTS The average number of substantive treatments was 2.5±1.1. Assessed by self-questionnaire in 1289 patients, overall adherence was 64.8%, in good agreement with the findings of the pneumologist in charge (p<0.0001). Control of asthma according to the GINA criteria was more successful in compliant patients (p<0.01). In univariate analysis, the most compliant participants were frequent exacerbator patients (p=0.02), those with nasal polyposis (p=0.01) and those receiving an anticholinergic agent (p<0.01), anti-IgE biotherapy (p<0.0001) or oral corticosteroids (p<0.01). The least compliant participants were younger (p<0.0001), active smokers (p<0.001), with shorter average disease duration (24.2±15.7 vs 29.1±18.7 years, p<0.0001) and a lower number of substantive asthma treatments (2.2±1 vs 2.6±1, p<0.0001). In multivariate analysis, age, length of disease and anti-IgE treatment were the only factors affecting therapeutic compliance. CONCLUSION In this large-scale study of severe asthmatic patients, 64.8% were compliant according to the MMAS-4© self-administered questionnaire and appeared to be better monitored according to the criteria defined in our study. Overall, adherence was more satisfactory among older patients and those whose disease had been evolving over a long period of time or were receiving anti-IgE biotherapy.

Abstract
BACKGROUND Understanding the effects of ethnicity in severe asthma is important for optimal personalized patient care. OBJECTIVE To assess ethnic differences in disease control, exacerbations, biological phenotype, and treatment in severe asthma in the United Kingdom. METHODS We compared demographics, type 2 biomarkers, lung function, asthma control, medications, and health care use between White and underrepresented ethnic group patients in the UK Severe Asthma Registry (UKSAR) and Optimum Patient Care Research Database (OPCRD). RESULTS A total of 3637 patients (665 from the underrepresented ethnic group) were included from UKSAR and 10,549 (577 from the underrepresented ethnic group) from OPCRD. Patients in the underrepresented ethnic group had higher levels of uncontrolled disease when measurements were made using the asthma control questionnaire in UKSAR (odds ratio [OR] = 1.47; 95% confidence interval [CI], 1.12-1.93) and the Royal College of Physicians 3 Questions in OPCRD (OR = 1.82; 95% CI, 1.27-2.60). Although exacerbation rates were similar, patients in the underrepresented ethnic group were more likely to have recently attended the emergency department (OR = 1.55; 95% CI, 1.26-1.92) or to have been hospitalized (OR = 1.31; 95% CI, 1.07-1.59) owing to asthma. Inflammatory biomarkers were consistently higher in the underrepresented ethnic group, including blood eosinophils in OPCRD (ratio = 1.12; 95% CI, 1.05-1.20) and in UKSAR blood eosinophils (ratio = 1.16; 95% CI, 1.06-1.27), FeNO (ratio = 1.14; 95% CI, 1.04-1.26), and IgE (ratio = 1.70; 95% CI, 1.47-1.97). Patients in the underrepresented ethnic group were more likely to be atopic in the UKSAR (OR = 1.32; 95% CI, 1.07-1.63) and OPCRD (OR = 1.67; 95% CI, 1.26-2.21), and less likely to be using maintenance oral corticosteroids at referral (OR = 0.75; 95% CI, 0.61-0.92). CONCLUSIONS Severe asthma patients from underrepresented ethnic groups presented with a higher disease burden and were more likely to attend the emergency department. They had a distinct phenotypic presentation and differences in medicine use, with higher levels of type 2 biomarkers.

Abstract
Introduction Severe asthma affects an estimated 3%–5% of people with asthma and is associated with frequent exacerbations, poor symptom control and significant morbidity from the disease itself, as well as high dose of inhaled and systemic steroids used to treat it. The introduction of specialist asthma services across the UK has attempted to improve quality of care and ensure that patients undergo a full systematic assessment prior to initiation of advanced biological therapies. However, improvements are required in the patient pathway to minimise avoidable harm. Objectives To define standards of care in areas where the evidence base is lacking through patient and healthcare professional (HCP) consensus. Methods The precision UK National Working Group of asthma experts identified 42 statements formed from 7 key themes. An online four-point Likert scale questionnaire was sent to HCPs working in asthma throughout the UK to assess agreement (consensus) with these statements; a subset of the statements formed a patient questionnaire. Consensus was defined as high if ≥75% and very high if ≥90% of respondents agreed with a statement. Results A total of 117/197 responses (59.3% response rate) were received from severe asthma patients (n=15) and HCPs (n=102) including respiratory physicians, respiratory nurse specialists, respiratory pharmacists, specialist physiotherapists and general practitioners. Consensus was very high in 25 (60%) statements, high in 12 (29%) statements and was not achieved in 5 (12%) statements. Based on the consensus scores, the precision UK National Working Group derived 10 key recommendations. These focus on referrals from primary and secondary care, accessing specialist asthma services, homecare provision for severe asthma patients and outcome measures. Conclusions Implementation of these 10 recommendations across the severe asthma pathway in the UK has the potential to improve outcomes for patients by reducing delays to assessment and initiation of advanced phenotype-specific therapies.

Abstract
The present prevailing inflammatory paradigm in asthma is of T2-high inflammation orchestrated by key inflammatory cells like Type 2 helper lymphocytes, innate lymphoid cells group 2 and associated cytokines. Eosinophils are key components of this T2 inflammatory pathway and have become key therapeutic targets. Real-world evidence on the predominant T2-high nature of severe asthma is emerging. Various inflammatory biomarkers have been adopted in clinical practice to aid asthma characterization including airway measures such as bronchoscopic biopsy and lavage, induced sputum analysis, and fractional exhaled nitric oxide. Blood measures like eosinophil counts have also gained widespread usage and multicomponent algorithms combining different parameters are now appearing. There is also growing interest in potential future biomarkers including exhaled volatile organic compounds, micro RNAs and urinary biomarkers. Additionally, there is a growing realisation that asthma is a heterogeneous state with numerous phenotypes and associated treatable traits. These may show particular inflammatory patterns and merit-specific management approaches that could improve asthma patient outcomes. Inhaled corticosteroids (ICS) remain the mainstay of asthma management but their use earlier in the course of disease is being advocated. Recent evidence suggests potential roles for ICS in combination with long-acting beta-agonists (LABA) for as needed use in mild asthma whilst maintenance and reliever therapy regimes have gained widespread acceptance. Other anti-inflammatory strategies including ultra-fine particle ICS, leukotriene receptor antagonists and macrolide antibiotics may show efficacy in particular phenotypes too. Monoclonal antibody biologic therapies have recently entered clinical practice with significant impacts on asthma outcomes. Understanding of the efficacy and use of those agents is becoming clearer with a growing body of real-world evidence as is their potential applicability to other treatable comorbid traits. In conclusion, the evolving understanding of T2 driven inflammation alongside a treatable traits disease model is enhancing therapeutic approaches to address inflammation in asthma.

Abstract
BACKGROUND Benralizumab is an IL-5Rα-directed monoclonal antibody indicated for patients with severe, uncontrolled eosinophilic asthma. OBJECTIVE To evaluate the long-term safety and tolerability of benralizumab among adults treated for up to 5 years. METHODS This analysis included adults treated with placebo or subcutaneous benralizumab 30 mg every 4 or 8 weeks in the 48-week SIROCCO, 56-week CALIMA, and 28-week ZONDA pivotal trials, who were subsequently enrolled in the 56-week double-blind BORA extension and continued assigned regimens or initiated benralizumab (if previously on placebo) for 16 to 40 weeks, before entering the open-label MELTEMI extension. Safety was measured by adverse and serious adverse event rates. Exacerbations were evaluated in patients with blood eosinophils greater than or equal to 300 cells/μL receiving high-dose inhaled corticosteroids at baseline. RESULTS Overall, 446 received treatment and 384 (86.1%) completed the study; 157 (35.2%) received benralizumab for 4 or more years. Adverse and serious adverse event rates (28.5-32.4 and 6.3-8.4 per 100 patient-years, respectively) were low, stable over time, and did not increase with exposure; few (n = 8) discontinued because of adverse events. Serious infections and hypersensitivity event rates were consistent with those in previous studies. Among patients with blood eosinophils greater than or equal to 300 cells/μL-high-dosage inhaled corticosteroids receiving benralizumab every 8 weeks, at least 75% had zero exacerbations annually during the integrated analysis period. CONCLUSIONS In patients with severe, uncontrolled eosinophilic asthma, long-term benralizumab was safe and well tolerated for up to 5 years. There were no new safety signals, and exacerbations were eliminated in similar percentages of patients as in predecessor studies.

Abstract
People with severe and difficult to control asthma can be a complex and heterogenous group of patients often with multiple comorbidities. Living with this disease imposes a huge physical and psychological burden upon the patient which requires a comprehensive, systematic and patient-focused assessment, using a wide range of clinical expertise from within the multidisciplinary team. This article describes a severe asthma systematic and multidimensional day case assessment, and the positive benefits that the authors perceive it offers for patient care. These benefits include a confirmed diagnosis, consideration of alternative diagnosis, enhanced adherence, medication optimisation, access to and gatekeeping of high-cost specialist medications, improved patient self-management skills and signposting to appropriate therapies. As a consequence, they believe that this facilitates better patient outcomes through a reduction in corticosteroid exposure, exacerbations and hospitalisation. This severe asthma multidisciplinary team day case approach offers more than just physical benefits when compared with the traditional medical model. Patient feedback reports an excellent patient experience, feeling listened to, understood, empowered and hopeful for the future.

Abstract
Asthma exacerbations are major contributors to disease morbidity in patients of all ages. To develop strategies that reduce the disease burden from exacerbations, it is helpful to review current concepts about the risk factors for asthma attacks and current approaches for prevention and treatment. Multiple factors contribute as risks and to the development of asthma exacerbations, including allergic and infectious processes. Viral respiratory infections, primarily from rhinoviruses, are the dominant exacerbating cause for most asthma patients. Allergic sensitization and allergen exposure contribute directly and enhance susceptibility for respiratory viral infections. Respiratory viruses infect airway epithelium to promote underlying type 2 inflammation with eosinophils, the predominant cellular component of increased inflammation. Deficiencies of antiviral interferon responses and generation have been identified that increase susceptibility to viral infections in asthma. Exacerbation treatment focuses on reducing airflow obstruction and suppressing inflammation, followed by improving long-term asthma control. Increasing concern exists regarding the side effects associated with frequent systemic corticosteroid use. A major advance has been the selective use of biologics to prevent exacerbations, primarily in patients with existing type 2 inflammation. Future research to prevent exacerbations is being directed toward antiviral activity and a more encompassing regulation of underlying airway inflammation.

Abstract
Introduction: Severe asthma and chronic rhinosinusitis (CRS), with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP), are heterogeneous diseases characterized by different mechanistic pathways (endotypes) and variable clinical presentations (phenotypes).Areas covered: This review provides the clinician with an overview of the prevalence and clinical impact of severe chronic upper and lower airways disease and suggests a novel therapeutic approach with biological agents with possible biomarkers. To select relevant literature for inclusion in this review, we conducted a literature search using the PubMed database, using terms 'severe airways disease' AND 'endotype' AND 'treatment.' The literature review was performed for publication years 2010-2020, restricting the articles to humans and English language publications.Expert opinion: The coronavirus disease (COVID-19) pandemic has brought forth many challenges for patients with severe airway disease and healthcare practitioners involved in care. These patients could have an increased risk of developing severe SARS-CoV-2 disease, although treatment with biologics is not associated with a worse prognosis. Eosinopenia on hospital admission plays a key role as a diagnostic and prognostic biomarker.

Abstract
The recent scientific research has provided clinicians with the tools for substantially upgrading the standard of care in the field of bronchial asthma. Nevertheless, satisfactory asthma control still remains an unmet need worldwide. Identifying the major determinants of poor control in different asthma severity levels represents the first step towards the improvement of the overall patients' management. The present review aims to provide an overview of the main unmet needs in asthma control and of the potential tools for overcoming the issue. Implementing a personalized medicine approach is essential, not only in terms of pharmacological treatments, biologic drugs or sophisticated biomarkers. In fact, exploring the complex profile of each patient, from his inflammation phenotype to his preferences and expectations, may help in filling the gap between the big potential of currently available treatments and the overall unsatisfactory asthma control. Telemedicine and e-health technologies may provide a strategy to both optimize disease assessment on a regular basis and enhance patients' empowerment in managing their asthma. Increasing patients' awareness as well as the physicians' knowledge about asthma phenotypes and treatment options besides corticosteroid probably represent the key and more difficult goals of all the players involved in asthma management at every level.
