SingleNucleotide Polymorphisms as Biomarkers of Mepolizumab and Benralizumab Treatment Response in Severe Eosinophilic Asthma. Int J Mol Sci 2024; 25:8139. [PMID: 39125709 PMCID: PMC11311889 DOI: 10.3390/ijms25158139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 07/09/2024] [Accepted: 07/18/2024] [Indexed: 08/12/2024] Open
Abstract
The most promising treatment options for severe uncontrolled asthma (SUA) have emerged in recent years with the development of monoclonal antibodies for blocking selective targets responsible for the underlying inflammation, such as mepolizumab and benralizumab. However, there is variability in treatment response that is not fully controlled. The variability of the response to mepolizumab and benralizumab could be influenced by single-nucleotide polymorphisms (SNPs), and it would be useful to detect these and use them as predictive biomarkers of response. We conducted a retrospective observational cohort study of 72 Caucasian patients recruited from a tertiary hospital with severe uncontrolled eosinophilic asthma treated with mepolizumab and benralizumab. Polymorphisms in the IL5 (rs4143832, rs17690122), RAD50 (rs11739623, rs4705959), IL1RL1 (rs1420101, rs17026974, rs1921622), GATA2 (rs4857855), IKZF2 (rs12619285), FCGR2A (rs1801274), FCGR2B (rs3219018, rs1050501), FCGR3A (rs10127939, rs396991), FCER1A (rs2251746, rs2427837), FCER1B (rs1441586, rs573790, rs569108), and ZNF415 (rs1054485) genes were analyzed by real-time polymerase chain reaction (PCR) using Taqman probes. The response was analyzed after 12 months of treatment. In patients under mepolizumab treatment, a treatment response defined as a reduction in exacerbations was associated with ZNF415 rs1054485-T (p = 0.042; OR = 5.33; 95% CI = 1.06-30.02), treatment response defined as a reduction in oral corticosteroids use was associated with the number of exacerbations in the previous year (p = 0.029; OR = 3.89; 95% CI = 1.24-14.92), and treatment response defined as improvement in lung function was associated with the age at the beginning of biological therapy (p = 0.002; OR = 1.10; 95% CI = 1.04-1.18), FCER1B rs569108-AA (p < 0.001; OR = 171.06; 95% CI = 12.94-6264.11), and FCER1A rs2427837-A (p = 0.021; OR = 8.61; 95% CI = 1.71-76.62). On the other hand, in patients under benralizumab treatment, treatment response, defined as a reduction in exacerbations, was associated with ZNF415 rs1054485-T (p = 0.073; OR = 1.3 × 108; 95% CI = 1.8 × 10-19-NA), FCER1B rs569108-AA (p = 0.050; OR = 11.51; 95% CI = 1.19-269.78), allergies (p = 0.045; OR = 4.02; 95% CI = 1.05-16.74), and sex (p = 0.028; OR = 4.78; 95% CI = 1.22-20.63); and treatment response defined as improvement in lung function was associated with polyposis (p = 0.027; OR = 9.16; 95% CI = 1.58-91.4), IKZF2 rs12619285-AA (p = 0.019; OR = 9.1; 95% CI = 1.7-75.78), IL5 rs4143832-T (p = 0.017; OR = 11.1; 95% CI = 1.9-112.17), and FCER1B rs1441586-C (p = 0.045; OR = 7.81; 95% CI = 1.16-73.45). The results of this study show the potential influence of the studied polymorphisms on the response to mepolizumab and benralizumab and the clinical benefit that could be obtained by defining predictive biomarkers of treatment response.

Ann Allergy Asthma Immunol 2024:S1081-1206(24)00421-6. [PMID: 38972449 DOI: 10.1016/j.anai.2024.06.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 06/28/2024] [Accepted: 06/28/2024] [Indexed: 07/09/2024]
Abstract
BACKGROUND Nasal polyps (NPs) are commonly associated with chronic rhinosinusitis (CRS). In keeping with the unified airway hypothesis, asthma and CRS with NP (CRSwNP) frequently co-occur, share a similar pathophysiology, and are often treated with oral corticosteroids (OCS); however, a need for alternative treatment options for patients with comorbid asthma and CRSwNP remains. OBJECTIVE To characterize the short- and long-term dual airway effectiveness of the anti-interleukin-5 monoclonal antibody, mepolizumab, in real-world patients with asthma and comorbid NP. METHODS Adult patients with CRSwNP who initiated mepolizumab from November 1, 2014, to September 30, 2021, were identified from 2 Merative MarketScan Research Databases. Outcomes were compared for the 12 months pre- and post-mepolizumab initiation and a variable follow-up period. Primary outcomes included the following: annual rate and proportion of patients with NP- and asthma-related exacerbations; NP surgery occurrences; all-cause OCS claims, number of OCS bursts, and daily OCS dose; all-cause and NP-related health care resource utilization. RESULTS During the 12 months post-index, patients experienced fewer NP- and asthma-related exacerbations, required fewer sinus surgeries, and reduced use of OCS, with fewer all-cause OCS claims and OCS bursts. Significant reductions in asthma exacerbation-related and NP-related health care resource utilization were also observed. CONCLUSION This study illustrated the near- and long-term real-world effectiveness of mepolizumab treatment, with a focus on dual lower and upper airway benefit from single-agent add-on therapy. These results may aid physicians in clinical decision-making for patients with asthma and comorbid CRSwNP with complex care needs.

Allergy 2024; 79:1195-1207. [PMID: 38164813 PMCID: PMC11062846 DOI: 10.1111/all.16002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 11/15/2023] [Accepted: 12/17/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Lung function is an independent predictor of mortality. We evaluated the lung function trajectories of a cohort of patients with asthma receiving biologic therapy. METHODS We identified 229 monoclonal antibody-naïve adult patients with moderate-to-severe asthma who initiated omalizumab, mepolizumab, or dupilumab between 2010 and 2022 in a large healthcare system in Boston, MA. Generalized additive mixed models were used to estimate the lung function trajectories during the 156 weeks following biologic initiation. Response was defined as an improvement in FEV1 or a decrease of ≤0.5% per year. The Kaplan-Meier estimator was used to assess time to no additional improvement in FEV1 in responders. All models were adjusted for age, sex, body mass index, smoking status, baseline exacerbation rate, and baseline blood eosinophil count. RESULTS Eighty-eight patients initiated mepolizumab, 76 omalizumab, and 65 dupilumab. Baseline eosinophil count was highest in the mepolizumab group (405 cells/mcL) and lowest for omalizumab (250 cells/mcL). Both FEV1 and FVC improved in the mepolizumab group (FEV1 + 20 mL/year; FVC +43 mL/year). For omalizumab, there was an initial improvement in the first year followed by decline with an overall FEV1 loss of -44 mL/year and FVC -32 mL/year. For dupilumab, both FEV1 (+61 mL/year) and FVC (+74 mL/year) improved over time. Fifty percent of the mepolizumab group, 58% omalizumab, and 72% of dupilumab were responders. The median time to no additional FEV1 improvement in responders was 24 weeks for omalizumab, 48 weeks for mepolizumab, and 57 weeks for dupilumab. CONCLUSION In this clinical cohort, mepolizumab, omalizumab, and dupilumab had beneficial effects on FEV1 and FVC with distinct post-initiation trajectories.

Abstract
Many different phenotypes that characterize severe asthma are supported by intricate pathomechanisms called endotypes. The latter are driven by molecular interactions, mediated by intercellular networks. With regard to the biological treatments of either allergic or non-allergic eosinophilic type 2 asthma, real-world studies have confirmed the positive effects of currently available antibodies directed against immunoglobulins E (IgE), interleukin-5 (IL-5) and its receptor, as well as the receptors of interleukins-4 (IL-4) and 13 (IL-13). The best way to treat severe asthma should be chosen based on the peculiar phenotypic and endotypic traits of each patient. This will lead to relevant improvements in both clinical and functional outcomes. In particular, biological therapies can change the lives of asthma patients with a strong impact on quality of life. Unfortunately, patients with severe non-type-2 asthma, who continue to have pertinent unmet needs, are not receiving satisfactory advances within the context of biological treatments. It is also hopeful that in the next future new therapeutic strategies will be specifically implemented for these people, perhaps offering them the opportunity to improve their current, mostly inadequate asthma management.

The effect of biologics in lung function and quality of life of patients with united airways disease: A systematic review. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. GLOBAL 2024; 3:100174. [PMID: 37915724 PMCID: PMC10616425 DOI: 10.1016/j.jacig.2023.100174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 11/03/2023]
Abstract
Background Increasing evidence supports the united airway disease concept for the management of upper and lower respiratory tract diseases, particularly in patients with asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). However, evidence for a combined approach in asthma and CRSwNP is scarce. Objective In this systematic review, we focused on the role of biologics in the lung function and quality of life in patients with severe asthma and CRSwNP. Methods We conducted a systematic search of 3 electronic databases using 2 search strategies to identify studies published from January 2010 to March 2022. Quality assessment was performed with the Critical Appraisal Skills Programme. Results Of 1030 studies identified, 48 original studies reporting data of benralizumab (12), dupilumab (14), mepolizumab (10), omalizumab (13), and reslizumab (2) were analyzed. Primary diagnosis was mostly asthma or CRSwNP, with only 15 studies, mainly observational, performed in populations with united airway disease. In total, 18 studies reported data on quality of life (mostly 22-item Sino-Nasal Outcome Test score), 8 on lung function (mostly FEV1), and 22 on both outcomes. Significant FEV1 and 22-item Sino-Nasal Outcome Test score improvements were consistently observed after 24-week treatment, and thereafter, mostly in real-world studies that included variable proportions of patients with asthma/CRSwNP. Conclusions The use of biologics in patients with severe asthma and CRSwNP was overall associated with significant improvements in lung function and quality of life. However, we observed a high heterogeneity of populations and outcome measurements across studies. Notwithstanding the need of larger studies, our results reinforce the joint management of asthma and CRSwNP as united airway disease in clinical practice.

Abstract
BACKGROUND Randomized trials of biologics in severe, uncontrolled asthma have excluded patients with a cumulative tobacco exposure of more than 10 pack-years. Therefore, our knowledge of the impact of smoking exposure on the clinical effects of biologics in severe asthma remains incomplete. However, because many patients with asthma are current or former smokers, investigating the potential impacts of tobacco exposure on the effects of biologic treatment is clinically important. OBJECTIVE To investigate the impact of smoking history and tobacco exposure on the effectiveness of biologic therapy in real-life patients with severe asthma. METHODS We used data from a complete nationwide cohort of patients with severe asthma who were receiving biologics, the Danish Severe Asthma Register. We divided patients according to smoking history and cumulative tobacco exposure and analyzed data at baseline and after 12 months of biologic treatment. RESULTS A total of 724 bio-naive patients were identified in the Danish Severe Asthma Register, 398 of whom had never been smokers (55%), 316 were previous smokers (44%), and 10 were current smokers (1%). Within the group of current and former smokers, 37% had 1 to 9 pack-years of tobacco exposure, 26% had 10 to 19 pack-years, and 37% had 20 or more pack-years of tobacco exposure. Patients with tobacco exposure had similar reductions in the number of exacerbations, reductions in maintenance oral corticosteroid use, and improvements in asthma symptoms compared with patients with 0 pack-years. CONCLUSION Former smoking history and lifetime tobacco exposure do not have an impact on the efficacy of biologics in patients with severe asthma.

Abstract
Severe eosinophilic asthma (SEA) is characterized by persistent airway inflammation and frequent exacerbations despite standard treatments. Mepolizumab, a monoclonal antibody that reduces eosinophil levels by targeting interleukin-5, has emerged as an add-on therapy for patients with SEA. This systematic review evaluated mepolizumab's efficacy and safety for treating SEA. A comprehensive literature search was conducted across major databases. Thirty-two studies with over 6,000 patients were included, comprising randomized controlled trials, open-label extensions, and real-world observational analyses. Study quality and risk of bias were assessed using standard tools. Meta-analysis was deemed inappropriate due to heterogeneity. Instead, a narrative synthesis was performed. Mepolizumab significantly reduced exacerbation rates by around 50% and improved symptoms and lung function compared to placebo in pivotal trials. Long-term open-label studies showed sustained reductions in exacerbations and stable lung function for up to 4.5 years. Real-world data demonstrated consistent 50%-90% exacerbation decreases across diverse patient populations over 6-24 months. Mepolizumab exhibited an acceptable safety profile, with mild injection site reactions and headaches as most common adverse events. While specific subgroups may show enhanced responses, mepolizumab displayed broad efficacy regardless of patient demographics or phenotypes. The extensive evidence provides robust support for mepolizumab as an efficacious and safe add-on treatment option for patients with severe, refractory eosinophilic asthma. Further high-quality comparative effectiveness research is warranted to optimize patient selection and positioning among emerging biologics.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:3670-3679.e2. [PMID: 37572752 DOI: 10.1016/j.jaip.2023.08.010] [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: 04/29/2023] [Revised: 07/26/2023] [Accepted: 08/03/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND The major problem at the Cleveland Allergy and Asthma Center was the need for additional therapy for severe eosinophilic asthma patients who were steroid-dependent or required frequent bursts of prednisone. OBJECTIVES The objectives of this study were to determine the efficacy of monthly mepolizumab (MP) injections up to 6½ years using Asthma Control Quesitonnaire-7 (ACQ-7), forced expiratory volume in 1 second (FEV1), forced expiratory flow at 25% to 75% (FEF25%-75%) overall and among super-responders, and to understand whether FEF25%-75% is an effective parameter to evaluate MP efficacy. METHODS We reviewed the charts of 67 patients with severe eosinophilic asthma and compared the results between 47 super-responders and the rest of the cohort regarding ACQ-6, ACQ-7, eosinophils, FEV1, and FEF25%-75%. The groups of super-responders and all other patients were described with respect to initial and current values of the study end points using medians and 25th and 75th percentiles. Changes from the initial to the current values in the study end points were measured using percent changes. The Wilcoxon signed rank test was used within each group to test the null hypothesis of 0 median percent change. RESULTS After 6½ years, there were no significant changes in FEV1. The FEF25%-75%, had a significant median percent increase of 40% among the super-responders (P < .001), which was substantially higher (P = .026) than the median percent increase of 13.8% observed among all other patients. CONCLUSIONS The use of MP up to 6½ years was safe and effective, with significant changes to ACQ-7 and FEF25%-75% associated with MP treatment, but not the FEV1. A higher magnitude of changes was observed among super-responders than the rest of the cohort. Changes in FEF25%-75% were more meaningful than changes in FEV1 in evaluating pulmonary function responsiveness of severe eosinophilic asthma to MP.

Abstract
Background: Asthma has a high healthcare burden globally, with up to 10% of the asthma population suffering from severe disease. Biologic agents are a newer class of asthma treatments for severe asthma, with good evidence for efficacy in clinical trials. Nevertheless, real-world studies of its impact on clinical outcomes are limited.Methods: This is an observational cohort study using administrative claims data. The study population consisted of patients aged ≥18 years who had a diagnosis of asthma and initiated mepolizumab after November 4, 2015 and had continuous medical and drug coverage in both the 365 days prior to and following mepolizumab initiation. In patients treated with mepolizumab, we described clinically significant asthma exacerbations by minimum continuous treatment thresholds following initiation of mepolizumab, medication switching patterns and chronic oral corticosteroid (≥28 days) use.Results: We identified 2,536 adults with asthma who initiated mepolizumab. There was an association toward reduction in severe asthma-related events over the first one year of exposure. We observed associations with reduced dispensings of oral corticosteroids over the first year after mepolizumab initiation. Very few patients switched to other biologics during the study period.Conclusions: Treatment with mepolizumab may be associated with fewer asthma-related events in the first year. Over the first one year after initiating mepolizumab, we found associations with decreased concomitant dispensings of oral corticosteroids and medium to high dose ICS/LABA. Additionally, most patients who initiated mepolizumab did not switch to other biologics.

Abstract
Severe asthma affects 3%-10% of the world's population, according to estimates by the Global Initiative for ASTHMA (GINA). Allergic asthma is one of the most common phenotypes of severe asthma and it is characterized by allergen-induced type 2 inflammation in which immunoglobulin E (IgE) is a key mediator, making it an important therapeutic target. The introduction of targeted biological therapies or treatments has entered the management for severe asthma in the era of precision medicine, and the goal of treatment is clinical remission of the disease. There is a significant percentage of patients with severe allergic asthma who do not respond to treatments and whose symptoms are not controlled. In this paper, a group of experts in the management of severe allergic asthma reviewed and evaluated the most relevant evidence regarding the pathophysiology and phenotypes of severe allergic asthma, the role of IgE in allergic inflammation, allergen identification, techniques, biomarkers and diagnostic challenges, available treatments and strategies for disease management, with a special focus on biological treatments. From this review, recommendations were developed and validated through a Delphi consensus process with the aim of offering improvements in the management of severe allergic asthma to the professionals involved and identifying the unmet needs in the management of this pathology.

Abstract
Allergic conditions, such as asthma, chronic urticaria, atopic dermatitis (AD), and eosinophilic esophagitis, have long been treated with oral and topical steroids which resulted in negative off-target effects. However, newer biologic medications are increasingly being developed and approved for treatment of these conditions. These medications have a variety of mechanisms of action to target pathophysiology specific to these diseases. As biologics become more targeted, fewer off-target effects are seen improving tolerability for patients as well as expanded options for treatment of these conditions. This review discusses monoclonal antibody therapies (omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, tezepelumab, and tralokinumab) including their safety and use in asthma, chronic urticaria, AD, and eosinophilic esophagitis.

Abstract
Background Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare vasculitis characterized by asthma, systemic manifestations, and blood and tissue eosinophilia. Objective To assess the effectiveness and safety of mepolizumab (anti-IL-5) and benralizumab (anti-IL-5Rα) in EGPA for 24 months. Methods We conducted a multicenter observational study, including patients with EGPA treated with anti-IL-5/Rα biologics in 9 Italian specialized facilities. Systemic disease activity, remission and relapse rate were evaluated from 3 to 24 months after treatment initiation. Respiratory outcomes, hematological parameters, corticosteroid (OCS) and immunosuppressants consumption were also assessed. Results 49 patients with relapsing-refractory EGPA were included [26 (53.1%) benralizumab 30mg, 20 (40.8%) mepolizumab 100mg, 3 (6.1%) mepolizumab 300mg]. Overall, 38.8% and 57.1% achieved remission after 12 and 24 months, respectively (69.2% benralizumab and 43.5% mepolizumab). Lower OCS intake and higher blood eosinophil count at baseline were associated with remission at 24 months. Both biologics exerted beneficial effects on severe asthma outcomes. Indeed, 61.2% (61.5% benralizumab and 60.8% mepolizumab) remained exacerbation-free during treatment. Lung function parameters showed improvements in the overall cohort (all p<0.05), but began to decline from month 12, especially with mepolizumab. Marked reduction in blood eosinophils was registered with mepolizumab (p<0.0001), while benralizumab depleted both eosinophils (p<0.0001) and basophils (p<0.0001). In general, 69.6% (76% benralizumab and 61.9% mepolizumab) of OCS-dependent patients lowered their daily dose by 75%, while 28.3% discontinued these drugs. Immunosuppressants were suspended in 88.2% of cases. Adverse events were reported in 8.2% of patients. Conclusions These real-world data suggest that anti-IL-5/Rα biologics are effective and safe in the long-term as add-on treatments for patients with EGPA.

Benralizumab Effectiveness in Severe Eosinophilic Asthma with Co-Presence of Bronchiectasis: A Real-World Multicentre Observational Study. J Clin Med 2023; 12:3953. [PMID: 37373648 DOI: 10.3390/jcm12123953] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/06/2023] [Accepted: 06/07/2023] [Indexed: 06/29/2023] Open
Abstract
Introduction: The co-presence of bronchiectasis (BE) in severe eosinophilic asthma (SEA) is common. Data about the effectiveness of benralizumab in patients with SEA and BE (SEA + BE) are lacking. Aim: The aim of this study was to evaluate the effectiveness of benralizumab and remission rates in patients with SEA compared to SEA + BE, also according to BE severity. Methods: We conducted a multicentre observational study, including patients with SEA who underwent chest high-resolution computed tomography at baseline. The Bronchiectasis Severity Index (BSI) was used to assess BE severity. Clinical and functional characteristics were collected at baseline and after 6 and 12 months of treatment. Results: We included 74 patients with SEA treated with benralizumab, of which 35 (47.2%) showed the co-presence of bronchiectasis (SEA + BE) with a median BSI of 9 (7-11). Overall, benralizumab significantly improved the annual exacerbation rate (p < 0.0001), oral corticosteroids (OCS) consumption (p < 0.0001) and lung function (p < 0.01). After 12 months, significant differences were found between SEA and SEA + BE cohorts in the number of exacerbation-free patients [64.1% vs. 20%, OR 0.14 (95% CI 0.05-0.40), p < 0.0001], the proportion of OCS withdrawal [-92.6% vs. -48.6, p = 0.0003], and the daily dose of OCS [-5 mg (0 to -12.5) vs. -12.5 mg (-7.5 to -20), p = 0.0112]. Remission (zero exacerbations + zero OCS) was achieved more frequently in the SEA cohort [66.7% vs. 14.3%, OR 0.08 (95% CI 0.03-0.27), p < 0.0001]. Changes in FEV1% and FEF25-75% were inversely correlated with BSI (r = -0.36, p = 0.0448 and r = -0.41, p = 0.0191, respectively). Conclusions: These data suggest that benralizumab exerts beneficial effects in SEA with or without BE, although the former achieved less OCS sparing and fewer respiratory-function improvements.

Abstract
Currently, three classes of monoclonal antibodies targeting type 2 inflammation pathways are available in Italy for the treatment of severe asthma: anti-IgE (Omalizumab), anti-IL-5/anti-IL-5Rα (Mepolizumab and Benralizumab), and anti-IL-4Rα (Dupilumab). Numerous randomized controlled trials (RCTs) and real-life studies have been conducted to define their efficacy and identify baseline patients' characteristics potentially predictive of favorable outcomes. Switching to another monoclonal antibody is recommended in case of a lack of benefits. The aim of this work is to review the current knowledge on the impact of switching biological therapies in severe asthma as well as on predictors of treatment response or failure. Almost all of the information about switching from a previous monoclonal antibody to another comes from a real-life setting. In the available studies, the most frequent initial biologic was Omalizumab and patients who were switched because of suboptimal control with a previous biologic therapy were more likely to have a higher baseline blood eosinophil count and exacerbation rate despite OCS dependence. The choice of the most suitable treatment may be guided by the patient's clinical history, biomarkers of endotype (mainly blood eosinophils and FeNO), and comorbidities (especially nasal polyposis). Due to overlapping eligibility, larger investigations characterizing the clinical profile of patients benefiting from switching to different monoclonal antibodies are needed.

Comorbidities Modify the Phenotype but Not the Treatment Effectiveness to Mepolizumab in Severe Eosinophilic Asthma. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:885-895.e13. [PMID: 36572182 DOI: 10.1016/j.jaip.2022.12.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 11/30/2022] [Accepted: 12/01/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Comorbidities in severe asthma are common and contribute to disease burden. The severe asthma phenotype and treatment response can be impacted by comorbid conditions. Real-world data on the use of mepolizumab in severe eosinophilic asthma (SEA) in the presence of comorbidities are needed to inform clinical practice. OBJECTIVE To investigate the impact of comorbid conditions on baseline phenotype in patients with SEA and assess the mepolizumab treatment effect by comorbidity status in SEA. METHODS Patients enrolled in the Australian Mepolizumab Registry (n = 309) were classified into subgroups defined by the presence or absence of comorbidities, including nasal polyps, aspirin-exacerbated airway disease, asthma-chronic obstructive pulmonary disease overlap (ACO), fungal sensitization, and obesity. Patient baseline characteristics were compared, and the impacts of comorbidity on phenotype, identified by differences in patient age and/or baseline biomarker levels and/or asthma severity, were assessed. The mepolizumab treatment effects on clinical and biological outcomes at 12 months were assessed. RESULTS Across comorbidity subgroups, mepolizumab reduced the rate of clinically significant exacerbations (range: 47%-77%), maintenance oral corticosteroid use (dose reduction: 4.2-13.3 mg/d), and improved symptom control (Asthma Control Questionnaire-5 score: 1.9-2.4 point reduction) and lung function (mean: 3.4-9.3 post-bronchodilator percent predicted forced expiratory volume in 1 second). Peripheral blood eosinophils were reduced (mean: 480-780 cells/μL). Comorbidities (nasal polyps, obesity, ACO, and fungal sensitization) modified the baseline phenotype. CONCLUSIONS Mepolizumab treatment is associated with comparable clinical improvements in patients with SEA and comorbidities. Mepolizumab effectively minimizes the disease impact and corticosteroid burden in patients with SEA.

Abstract
Severe Uncontrolled Asthma (SUA) counts for more than 25% of cases of severe asthma. The main factors that impair the quality of life of these patients are high doses of oral corticosteroids, the presence of exacerbations, and reduced lung function. The objective of this study was to evaluate, in real life, the clinical improvement of patients with SUA treated with anti-interleukin 5 (IL5) therapies: mepolizumab and benralizumab, together with the search for biomarkers associated with the response. We conducted a retrospective observational cohort study that included patients with severe uncontrolled eosinophilic asthma in a tertiary hospital receiving biological therapies. Three types of response were evaluated: improvement in lung function, reduction in exacerbations, and decrease in the use of oral corticosteroids. After 12 months of treatment, significant reductions were found in the number of exacerbations, the use of oral corticosteroids, and blood eosinophil levels for both biological therapies (p < 0.001). Lung function improved, achieving a significant improvement in %FEV1 (p < 0.001), as well as asthma control, with a significant increase in asthma control test (ACT) scores in both therapies. The markers associated with the corticosteroid-saving effect were the low doses of oral corticosteroids and absence of exacerbations for mepolizumab, and higher blood eosinophilia, absence of chronic obstructive pulmonary disease (COPD), and reduction in oral corticosteroid cycles for benralizumab. The greatest improvement in lung function in both therapies was linked to lower previous FEV1 levels and absence of other respiratory diseases. The reduction in exacerbations was associated with absence of exacerbations the previous year for mepolizumab and never smokers for benralizumab. The results of this real-life study confirm the clinical benefit obtained after the introduction of an anti-IL5 biological therapy and the possible predictive biomarkers of response to treatment.

Abstract
Purpose The German Asthma Net (GAN) operates a Severe Asthma Registry that provides an overview of the clinical presentation and management of patients with severe asthma. Based upon data from the GAN registry, the MepoGAN study aimed to describe clinical profiles and treatment outcomes of patients who were treated with the anti-IL-5 monoclonal antibody mepolizumab (NucalaTM) in routine practice in Germany. Patients and Methods The MepoGAN study is a descriptive retrospective non-interventional cohort study. Mepolizumab patients enrolled in the GAN registry were evaluated with results being described in two different data sets: Cohort 1 (n=131) started on mepolizumab when the patients entered the registry. Results were reported after 4 months of therapy. Patients in Cohort 2 (n=220) were on treatment with mepolizumab at the time of enrollment and follow-up data were collected after a further year of treatment. Outcome measures included asthma control, lung function, disease symptoms, OCS use, and exacerbations. Results Patients enrolled in the registry who started on mepolizumab in Cohort 1 had a mean age of 55 years, were former smokers in 51% of the cases, had a mean blood eosinophil count of 500 cells/μL, and frequently had maintenance OCS use (55%). In this real-world setting, mepolizumab therapy was associated with a clinically relevant reduction in blood eosinophils (-445.7 cells/μL), OCS use (-30%), and improvement in asthma control. Fifty-five percent (vs 10% at baseline) of the patients reported controlled or partially controlled asthma 4 months after starting therapy. In patients who were already treated with mepolizumab at registry enrollment (Cohort 2), asthma control and lung function remained stable after a further year of observation. Conclusion The GAN registry data confirm the effectiveness of mepolizumab in a real-world setting. Treatment benefits are maintained over time. While the asthma of patients treated in routine practice was more severe, the results observed with mepolizumab are broadly consistent with RCTs.

Abstract
Objective: Mepolizumab is an anti-IL-5 monoclonal antibody that has shown, in different trials, the capacity to induce a reduction of exacerbations, an improvement of asthma control and a significant oral corticosteroid (OCS)-sparing effect. At present, there is limited real-life data about its long-term effects. The aim of the study was to evaluate the long-term effects of mepolizumab in real-life.Methods: We conducted a 36-months single-center retrospective study in 51 patients suffering from severe eosinophilic asthma treated with mepolizumab 100 mg/4 weeks. Clinical outcomes (symptoms, annual asthma exacerbation rates) were monitored. Additionally, we estimated annualized OCS dosage before and after mepolizumab treatment. Mepolizumab retention rate in the follow-up period was also evaluated.Results: A significant decrease of the annual rate of asthma exacerbations in association with significant changes in asthma control was observed. Specifically, the exacerbation rate significantly fell from 5.1 ± 4 per person/year in the pre-mepolizumab treatment period to 0.8 ± 1.2 per person/year in the 12-follow-up. The clinical benefit was maintained throughout the study follow up period of 36 months. Mepolizumab treatment induced significant changes in both ACT and ACQ5 scores. The majority of patients (65.2%) experienced a more pronounced improvement of 50% or more in SNOT-22. A mean cumulative OCS exposure reduction of 5365.5 mg over a 3-year period for patients receiving mepolizumab was estimated. The drug retention rate was: 96% at 12 months; 93.7% at 18 months, 88.9% at 24 months and 82.3% at 36 months.Conclusions: Our real-life results confirm that mepolizumab treatment allows to control asthma symptoms, reduce exacerbations and OCS exposure in a significant and sustained manner.

Abstract
Club cell 10-kDa protein (CC10) is a documented biomarker for airway obstructive diseases. Primarily produced by nonciliated club cells in the distal airway and in nasal epithelial cells, CC10 suppresses Th2 cell differentiation and Th2 cytokine production. In this study, we aimed to determine whether CC10 can also be used as an alternative biomarker for identifying Type 2 (T2) asthma. 74 patients with asthma, and 24 healthy controls were enrolled in the study. T2-high asthma was defined as elevation in two or more biomarkers, such as sputum eosinophilia ≥ 3%, high blood eosinophils ≥ 300/µL, or high FeNO ≥ 30 ppb. T2-low asthma was defined as no elevation in biomarkers. Enzyme-linked immunosorbent assay (ELISA) was used to assess the CC10 levels in plasma. The plasma CC10 level in patients with T2-high asthma was lower than that of patients with T2-low asthma and healthy controls (P < 0.05). To distinguish between T2-high and T2-low phenotype in patients with asthma, a receiver-operating characteristic (ROC) analysis was performed. It showed a sensitivity of 58.1% and specificity of 78.0% when using 22.74 ng/ml of plasma CC10. Correlation analysis indicated that the plasma CC10 level was inversely correlated with sputum eosinophil, blood eosinophil, and FeNO, and positively correlated with log PD20. However, no correlation with sputum neutrophil percentages, macrophage percentages, IgE, or lung function was found. Plasma CC10 is potentially useful in predicting T2-high and T2-low asthma. Lower plasma CC10 was associated with enhanced airway hyperresponsiveness, and Type 2 inflammation.

Abstract
In recent years, the more widespread availability of biological drugs with specific mechanisms of action has led to significant breakthroughs in the management of severe asthma. Over time, numerous randomised clinical trials have been conducted to evaluate the efficacy and safety of these biologics and define the eligibility criteria of patients suitable for various therapeutic options. These studies were conducted under controlled conditions not always applicable to real life. For this and other reasons, real-world evidence and pragmatic studies are required to provide useful information on the effectiveness of biological drugs and their safety, even in the long term. Because differences in outcomes have sometimes emerged between clinical trials and real-life studies, it is important to clarify the causes of these discrepancies and define the significance of the results of studies conducted in the course of daily clinical practice. Thus, a scientific debate is ongoing, and no consensus has been reached. The purpose of this narrative review is to analyse the differences between randomised trials and real-world evidence studies, focusing on their roles in guiding clinicians among different therapeutic options and understanding the reasons for the large discrepancies often found in the results obtained.

Abstract
Asthma is a common respiratory disorder in Canada for which biologics may be prescribed for poorly controlled illness. Treatment with biologics, however, is sometimes inappropriately discontinued due to misconceptions regarding their potential immunologic effects, and concerns surrounding their continued use in severe asthma during the COVID-19 pandemic continue to propagate. Biologics can still be administered in a majority of health and treatment conditions. With regard to cardiac-related issues such as hypertension or cardiovascular disease (CVD), there is no solid evidence that suggests biologics should be withheld, as the benefits of treatment outweigh the risks. Asthmatic patients on biologic treatment should also continue treatment if they have, or are currently being treated for, a respiratory infection, including COVID-19. Evidence also indicates the importance of maintaining asthma control to reduce the risk of severe COVID-19 infection. Biologic treatment can be administered in severe asthmatic patients with bronchiectasis, though further evidence is needed to better understand the benefits. Biologic treatment should be continued postsurgery to reduce postoperative respiratory complications, as well as throughout the course of pregnancy. Regarding concerns over vaccine administration, nearly all vaccines can be given without interruption of biologic treatment in patients with severe asthma or allergic conditions. Appropriate screening for respiratory illnesses, such as COVID-19, continues to be warranted in clinical practices to reduce the risk of transmission. As recommendations from public health and regulatory agencies have been lacking, this guidance document addresses the administration of biologics in different health circumstances and respiratory illness screening during the COVID-19 pandemic.

Abstract
We report a case of severe uncontrolled allergic and eosinophilic asthma in which omalizumab had led to a fast remission. After 18 months, mepolizumab was added to omalizumab because of increased blood eosinophils and a deterioration of asthma control. Asthma was then under control for the next 18 months. Discontinuation of mepolizumab in the ensuing 6 months led to a decrease in asthma control and an increased eosinophilia. The introduction of benralizumab resulted in an immediate increase of lung function, asthma control test (ACT), and symptom relief. Before the introduction of biologics, the patient was on the list for transplantation due to respiratory insufficiency. High-resolution CT scans before and after biologic therapy demonstrated a reduction of bronchial wall thickening and mucous plugging as well as an increase in bronchial caliber. The patient did therefore not need a transplant. We conclude that the dual use of biologics may be efficient in some cases of severe asthma.

Abstract
Background: Mepolizumab 300 mg is an approved treatment option for patients with eosinophilic granulomatosis with polyangiitis (EGPA), yet, the adequacy of 100 mg of mepolizumab in disease control is controversial.Objective: To evaluate the sinonasal and respiratory outcomes of EGPA patients treated with 100 mg mepolizumab for one year.Methods: Evaluations of 11 patients were made of the sinonasal outcome test (SNOT-22) (nasal, otologic, sleep, and emotional domains), asthma control test (ACT), forced expiratory volume in 1s (FEV1), blood eosinophil counts and oral steroid doses before mepolizumab treatment (T0) and at the 6th (T6) and 12th (T12) months.Results: A significant decrease was observed in the total SNOT-22 scores in the 6th month, after which the scores continued to be stable until the 12th month. (SNOT-22 median (IQR); T0: 70(53-82); T6: 19(4-35); T12: 11(6-40); T0-T6, p = 0.02; T6-T12, p = 0.85). In the subdomains of SNOT-22, nasal and sleep-related domains improved significantly in the first 6 months, and the otologic and emotional domains only improved from baseline in the 12th month. There was a significant decrease in blood eosinophil counts in the 6th month and oral steroid dose in the 12th month (eosinophils, median(IQR), T0: 1000(700-1800), T6: 100(0-200), p = 0.02; OCS dose, median(IQR), T0: 16(8-16); T6: 4(0-4); T12: 0(0-4); T0-T12, p = 0.002). A significant improvement was observed in ACT values in the 6th month (ACT median (IQR); T0:16(8-18); T6: 22(21-25); p = 0.01).Conclusion: Mepolizumab 100 mg provided a significant decrease in SNOT-22 values, especially in nasal and sleep domains, eosinophil counts and OCS dose in the 6th month.

Abstract
Asthma is a prevalent chronic pulmonary condition with significant morbidity and mortality. Tobacco smoking is implicated in asthma pathophysiology, diagnosis, prognosis and treatment. Smokers display increased prevalence and incidence of asthma, but a causal association cannot be claimed using existing evidence. Second-hand smoking and passive exposure to tobacco in utero and early life have also been linked with asthma development. Currently, approximately one-fourth of asthma patients are smokers. Regular smokers with asthma might display accelerated lung function decline and non-reversible airflow limitation, making their distinction from chronic obstructive pulmonary disease patients challenging. Asthma patients who smoke typically have uncontrolled disease, as shown by increased symptoms, more exacerbations and impaired quality of life. On the other hand, smoking cessation improves lung function and asthma severity. Thus, asthma patients and their caregivers should be actively questioned about their smoking status at each medical encounter, and smoking cessation ought to be strongly encouraged both for patients with asthma and their close contacts. Smokers with asthma should be provided with comprehensive smoking cessation interventions on top of other anti-asthma medications.

Abstract
OBJECTIVE To investigate the changes in asthma exacerbation, as well as in oral corticosteroid (OCS) use, exacerbation-related healthcare resource utilization (HRU), and healthcare costs before and after mepolizumab treatment initiation in patients with severe asthma who started treatment with mepolizumab in a real-world clinical setting in Japan. METHODS A retrospective, observational, self-controlled study was conducted in Japan using a hospital-based administrative claims database. Patients who were diagnosed with asthma and who were new users of mepolizumab were included in the study. The primary outcome was the incidence rate of any asthma exacerbation/patient-year during the 12-month period before (baseline period) and after (follow-up period) the first mepolizumab prescription. Secondary outcome measures included the proportion of patients with ≥1 any asthma exacerbation, patients with exacerbation requiring hospitalization, the incidence rate of exacerbations requiring hospitalization/patient-year, the median daily OCS dose (OCS sparing effect), exacerbation-related HRU (hospitalization length, the proportion of patients with emergency visits, and the number of emergency/outpatient visits), and associated costs. RESULTS Of the 377 patients included, 56.2% were ≥65 years of age. Following the first mepolizumab prescription, incidence rates for any asthma exacerbation were reduced by 40.6% (4.00/patient-year to 2.38/patient-year; the incidence rate ratio [95% confidence interval]: 0.60 [0.53-0.67]; p < 0.0001) from the baseline to follow-up periods. The incidence rate of exacerbations requiring hospitalization was reduced by 55.8% (0.37/patient-year to 0.16/patient-year) from the baseline to follow-up periods. The proportion of patients experiencing any exacerbation decreased from 84.4% to 57.8% and those requiring hospitalization decreased from 23.9% to 10.3% both from the baseline to follow-up periods. The median daily OCS dose decreased by 44.6% (median [interquartile range]: 6.7 [4.7-9.9] mg/day to 3.3 [0.9-5.6] mg/day) from the last baseline quarter to the 4th quarter of the follow-up period. All exacerbation-related HRUs decreased from the baseline to follow-up periods. Inpatient cost reduced by >50% (123,279 Japanese Yen [JPY]/patient-year vs. 57,283 JPY/patient-year), reducing the total cost by 80,716 JPY from the baseline to follow-up periods. CONCLUSION Mepolizumab was effective in treating patients with severe asthma by reducing the incidence rates of exacerbations and exacerbation requiring hospitalization, OCS dose, exacerbation-related HRU, and cost in routine clinical practice in Japan.

Abstract
Sex is considered an important risk factor for asthma onset and exacerbation. The prevalence of asthma is higher in boys than in girls during childhood, which shows a reverse trend after puberty—it becomes higher in adult females than in adult males. In addition, asthma severity, characterized by the rate of hospitalization and relapse after discharge from the emergency department, is higher in female patients. Basic research indicates that female sex hormones enhance type 2 adaptive immune responses, and male sex hormones negatively regulate type 2 innate immune responses. However, whether hormone replacement therapy in postmenopausal women increases the risk of current asthma and asthma onset remains controversial in clinical settings. Recently, sex has also been shown to influence the pathophysiology of asthma in its relationship with genetic or other environmental factors, which modulate asthmatic immune responses in the airway mucosa. In this narrative review, we highlight the role of sex in the continuity of the asthmatic immune response from sensing allergens to Th2 cell activation based on our own data. In addition, we elucidate the interactive role of sex with genetic or environmental factors in asthma exacerbation in women.

Abstract
Obesity is a major risk factor for the development of asthma, and the prevalence of obesity is higher in people with asthma than in the general population. Obese people often have severe asthma-recent studies in the United States suggest that 60% of adults with severe asthma are obese. Multiple mechanisms link obesity and asthma, which are discussed in this article, and these pathways contribute to different phenotypes of asthma among people with obesity. From a practical aspect, changes in physiology and immune markers affect diagnosis and monitoring of disease activity in people with asthma and obesity. Obesity also affects response to asthma medications and is associated with an increased risk of co-morbidities such as gastroesophageal reflux disease, depression, and obstructive sleep apnea, all of which may affect asthma control. Obese people may be at elevated risk of exacerbations related to increased risk of severe disease in response to viral infections. Interventions that target improved dietary quality, exercise, and weight loss are likely to be particularly helpful for this patient population.

[PMID: 34922515 PMCID: PMC8684207 DOI: 10.1186/s12890-021-01785-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 12/08/2021] [Indexed: 11/10/2022] Open
Abstract
Background Benralizumab, a monoclonal antibody targeting the human interleukin-5 (IL-5) receptor (IL-5R), was used before marketing authorisation in Spain in a real world setting as part of an early-access programme (EAP) to treat patients with severe eosinophilic asthma with prior insufficient response or intolerance to anti-IL5 treatment (mepolizumab or reslizumab). The objective of this study is to describe the patient profile candidate for treatment and to assess benralizumab effectiveness. Methods This is an observational, retrospective, multicentre study in severe eosinophilic asthma patients refractory to other biological agents targeting the IL-5 pathway. Baseline characteristics included closest data, from the previous 12 months, to benralizumab treatment onset (index date). Patients were followed until the last treatment dosage while EAP was active (March to December 2018). Effectiveness was evaluated versus baseline, in patients who received at least three doses, with asthma control test (ACT), Mini Asthma Quality of Life Questionnaire (MiniAQLQ), annual severe exacerbation rate, oral corticosteroids treatment (OCS) and asthma-related healthcare resources utilization. Results Twenty-seven patients treated with benralizumab were included in the analysis. Effectiveness was assessed in 19 patients. Both questionnaires showed clinically meaningful differences, i.e. ACT score ≥ 3 and MiniAQLQ score ≥ 0.5, compared with baseline [mean (SD), 3.3 (6.8) and 1.2 (1.9), respectively]. Patients treated with OCS decreased during follow-up from 88.9% (n = 24/27) at baseline to 78.9% (n = 15/19) and 31.6% (n = 6/19) had an OCS dose reduction ≥ 50%. The difference in annual severe exacerbation rate during follow-up showed a significant reduction vs. baseline (2.12 per patient-year, 95% CI 0.99–3.24, p = 0.002). The differences in annual rate of non-scheduled primary care and specialist visits during follow-up indicated a significant decrease [2.28 per patient-year (95% CI 1.55–3.01; p < 0.001) and 1.47 per patient-year (95% CI 0.65–2.30; p = 0.004), respectively], as well as the difference in annual rate of number of emergency department visits [1.18 per patient-year (95% CI 0.51–1.85; p = 0.007)]. Conclusions These results suggest that severe eosinophilic asthma patients receiving benralizumab, presented clinically meaningful improvement in asthma control and asthma-related QoL as well as OCS dose reduction. Results also aim to significant reductions in annual severe exacerbation rates, non-scheduled primary care and specialist visits, and emergency department visits rates.

Abstract
Introduction Type 2-high severe asthma (T2-SA) is often associated with several comorbidities. To this extent, the coexistence of T2-SA and bronchiectasis (BE) is considered an emerging phenotype. Methods We performed a prospective observational multicentre study, including T2-SA patients. Chest HRCT confirmed the presence of BE. Data on exacerbations, pulmonary function, Asthma Control Test (ACT), chronic mucus hypersecretion (CMH), chronic rhinosinusitis (CRS), oral corticosteroid (OCS) dosage, eosinophils in peripheral blood and FeNO were recorded. The Bhalla score was used for radiological assessment of T2-SA+BE patients and the Bronchiectasis Severity Index (BSI) was calculated. Results A total of 113 patients (mean age 55 ± 11 years, 59.3% female) were enrolled. Co-presence of BE was confirmed in 50/113 (44.2%) patients who identified the T2-SA+BE group. CRS and CRSwNP were more prevalent in T2-SA+BE vs T2-SA [respectively, 42/50 (84%) vs 37/63 (58.7%), p = 0.004 and 27/50 (54%) vs 27/63 (42.9%), p = 0.0165]. Furthermore, T2-SA+BE patients reported more CMH compared to T2-SA [29/50 (58%) vs 15/63 (23.8%), p = 0.0004], were more frequently on chronic OCSs intake [28/50 (56%) vs 22/63 (34.9%), p = 0.0357] and experienced more exacerbations/year [10 (4-12) vs 6 (4-12), p = 0.0487]. In a multivariate logistic regression model, the presence of CRS, CMH and daily OCS intake were associated with BE presence with a 78% (95% CI: 69-88) accuracy. Median Bhalla score was 18.3 (16-20) (Mild radiological severity). Median BSI was 6 (4-8) and only 6/50 (12%) had a BSI score ≥9. Significant inverse linear relationship between BSI and ACT (r = -0.6095, p < 0.0001), FEV1% (r = -0.3297, p = 0.0353) and FEV1 mL (r = -0.4339, p = 0.0046) were found. Conclusion Type 2 inflammation could have a causative role in BE development. Chest HRCT is mandatory when a diagnosis of T2-SA is made, especially in presence of CRS, CMH and chronic OCS intake. Early BE detection may be crucial to improve T2-SA patients' outcomes.

Abstract
Background The efficacy of mepolizumab is well documented in severe eosinophilic asthma (SEA), although the stringent selection criteria adopted by SEA clinical trials limits the generalizability of results. Objective Our study evaluated the effectiveness and safety of mepolizumab in patients with SEA in Spain. The primary efficacy endpoint was the change in the rate of clinically significant asthma exacerbations 12 months after starting mepolizumab compared to the baseline rate in the 12 months prior to treatment. Patients were stratified by baseline blood eosinophil counts. Methods We conducted a multicentric observational cohort study of SEA patients treated with mepolizumab across 24 specialized hospital asthma units in Spain. Severe exacerbation rate, lung function, oral corticosteroid use (OCS) and asthma control test (ACT) were retrospectively collected and compared during the 12-month pre- and post-mepolizumab treatment. Adverse events were also investigated. Results A total of 318 patients with SEA were included (mean age: 56.6 years, 69.2% female). Exacerbation rates decreased by 77.5%, and 50.6% of patients did not suffer any exacerbations during the 12 months of treatment. The difference in forced expiratory volume in 1 s (FEV1) pre- and post-bronchodilator after starting mepolizumab was 0.21 (0.46) L (95% CI 0.14–0.27) (p < 0.001). Exacerbations and lung function significantly improved across all eosinophil subgroups. Among the 98 patients on OCS, 47.8% were able to discontinue this treatment and the mean daily dose was decreased by 59.9%. The baseline ACT score was 14.1, increasing by a mean (SD) of 6.7 points (1.9) at 12 months. Adverse events related to mepolizumab were uncommon. Conclusions This real-world study of SEA patients confirms that mepolizumab is effective in reducing clinically meaningful exacerbations, improving lung function, and decreasing OCS dependence and mean OCS dose at 12 months, irrespective of baseline eosinophil counts.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) affects around 60% of patients with severe eosinophilic asthma (SEA). Benralizumab was recently approved for SEA add-on treatment. OBJECTIVE To assess the real-world effectiveness of benralizumab in SEA with or without CRSwNP. METHODS We conducted a multicenter observational study, including patients with SEA treated with benralizumab for 24 weeks in 12 Italian specialized facilities. Asthma exacerbations, Asthma Control Test (ACT), lung function, oral corticosteroid (OCS) dosage, and eosinophil and basophil count in peripheral blood were recorded at baseline and after 4, 12, and 24 weeks. The 22-item Sino-Nasal Outcome Test (SNOT-22) and Lund-Mackay scores were assessed at baseline and after 24 weeks in SEA+CRSwNP. RESULTS A total of 137 patients with late-onset SEA were included; 57.7% (79 of 137) showed the copresence of CRSwNP. Overall, severe asthma exacerbations decreased from 4 (3-6) to 0 (0-2) (P < .0001) after 24 weeks of treatment, and significant improvements were observed as early as 4 weeks in ACT score, OCS dosage, forced expiratory volume in the 1st second (FEV1)%, FEV1 (L), forced vital capacity (FVC)%, FEV1/FVC% (P < .0001), and forced expiratory flow between 25% and 75% of FVC (FEF25-75)% (P = .0022). Eosinophils and basophils in peripheral blood were rapidly depleted. In patients with SEA+CRSwNP, SNOT-22 decreased from 46 (39.5-64.5) to 32 (19-46) (P < .0001). Furthermore, in comparison with SEA, they showed enhanced responses with regard to ACT minimal clinically important difference (P = .0387), FEV1% (P = .017), FEV1 (L) (P = .02), and FEF25-75% (P = .0362). CONCLUSIONS These real-world data suggest that benralizumab can represent a valid add-on therapeutic option for patients with SEA, especially with comorbid CRSwNP.

Abstract
Airway inflammation represents an important characteristic in asthma, modulating airflow limitation and symptom control, and triggering the risk of asthma exacerbation. Thus, although corticosteroids represent the cornerstone for the treatment of asthma, severe patients may be dependent on oral corticosteroids (OCSs). Fortunately, the current humanised monoclonal antibodies (mAbs) benralizumab, dupilumab, mepolizumab, omalizumab, and reslizumab have been proven to induce an OCS-sparing effect in randomized controlled trials (RCTs), thus overcoming the problem of OCS dependence in severe asthma. Nevertheless, a large discrepancy has been recognized between selected patients enrolled in RCTs and non-selected asthmatic populations in real-world settings. It is not possible to exclude that the OCS-sparing effect of mAbs resulting from the RCTs could be different than the real effect resulting in clinical practice. Therefore, we performed a systematic review and correlation analysis to assess whether mAbs are effective in eliciting an OCS-sparing effect and overcoming the OCS dependence in severe asthmatic patients in real-world settings. Overall, real-world studies support the evidence that OCS dependence is a real condition that, however, can be found only in a small number of really severe asthmatic patients. In most patients, the dependence on OCS can be related to modifying factors that, when adequately modulated, may lead to a significant reduction or suspension of OCS maintenance. Conversely, in severe asthmatics in whom OCS resistance is proved by a high daily dose intake, mAbs allow reversion of the OCS dependence, leading to the suspension of OCS therapy in most patients or >50% reduction in the daily OCS dose.

Abstract
BACKGROUND The association of bronchiectasis (BE) in patients with severe eosinophilic asthma (SEA) is quite frequent. Mepolizumab is a well-recognized treatment for SEA; we aim to evaluate its effectiveness in SEA patients with and without BE in real-life. METHODS We performed a single-center retrospective pilot study, including patients with SEA treated with mepolizumab for one year. Asthma control test (ACT), lung function, annual exacerbations rate, oral corticosteroid dosage, FeNO, chronic mucous secretions, blood and sputum eosinophils were recorded at baseline and after 6 and 12 months. RESULTS we included 32 patients (mean age: 52.3 ± 10, 59% female). 50% showed co-presence of bronchiectasis, (SEA + BE). Significant improvements were found in ACT [(13.8 ± 4.6 to 20.7 ± 4.1, p = 0.0009) and (13 ± 4.8 to 20.7 ± 4.6, p = 0.0003)], annual exacerbations rate [from 7 (4-12) to 0 (0.00-0.75) and from 8 (4-12) to 0 (0-1), p < 0.0001], and blood eosinophils count [748 cells/μL (400-1250) vs. 84 cells/μL (52.5-100), and from 691 cells/μL (405-798) vs. 60 cells/μL (41-105), p < 0.0001] in SEA and SEA + BE group respectively, already after 6 months of treatment. A reduction in daily oral corticosteroids intake at 12 months was shown [from 15 mg (0-25) to 0 mg (0-0), p = 0.003 and from 8.8 mg (0-25) to 0 mg (0-0) (p = 0.01)] in both SEA and SEA + BE, respectively. Similar results were found, comparing SEA + BE patients based on the severity of bronchiectasis. CONCLUSIONS Mepolizumab effectively improves asthma symptoms control, reducing annual exacerbations and corticosteroid intake in all patients with SEA, even in the subgroup with coexisting bronchiectasis, independently of their severity.

Abstract
INTRODUCTION Dupilumab is a monoclonal antibody targeting IL-4Rα recently licensed for severe asthma (SA). A Named Patients Program (NPP) was created in Italy before its commercial availability for SA patients with no other available therapeutic options. We aimed to assess the real-world effectiveness of dupilumab in patients with SA and unmet needs. METHODS We performed a multicentre retrospective study, including SA patients admitted to the NPP treated with dupilumab for 12 months. Data on the number of exacerbations, Asthma Control Test (ACT), pre-bronchodilator FEV1%, oral corticosteroids (OCSs) use, FeNO and eosinophils count in peripheral blood were recorded at baseline and after 3, 6, and 12 months. RESULTS We included 18 SA patients (mean age 53.3±12.4 years, 66.7% female). Eleven (61.1%) were OCSs dependent. Five patients (27.8%) received previous anti-IgE and/or anti-IL-5 agents. A significant improvement in ACT score (from 15.7±5.1 to 18.8±4.8, p=0.023), OCSs intake [10 (5-25) mg/day to 0 (0-5) mg/day, p=0.0333] and FeNO [from 25 (20-80) ppb to 21 (10.9-55.3) ppb, p=0.0190] was already detected after 3 months of treatment. After 12 months, a statistically significant decrease in the number of exacerbations from 2 (0-3) to 0 (0-1) (p<0.0068) and increase in FEV1% from 73.5±19.5% to 87.1±19.2% (p=0.0407) and ACT to a mean value of 22.4±1.7 (p<0.0001) and the interruption of OCSs in all the patients (p<0.0001) was observed. A transient increase in the eosinophil count was observed in five patients (above 1000 cells/μL in 2 cases) after 3 months, without any clinical effect. CONCLUSION Dupilumab improved all the explored clinical outcomes after 12 months, and the transient hypereosinophilia did not modify treatment response. These real-world data confirm the results reported in randomized controlled trials and provide an important opportunity to characterize the clinical impact of the treatment in a non-trial setting. Further real-world studies with a larger cohort of patients are needed to confirm these findings.

Difficult and Severe Asthma in Children. CHILDREN-BASEL 2020; 7:children7120286. [PMID: 33322016 PMCID: PMC7764801 DOI: 10.3390/children7120286] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 12/04/2020] [Accepted: 12/08/2020] [Indexed: 12/24/2022]
Abstract
Asthma is the most frequent chronic inflammatory disease of the lower airways affecting children, and it can still be considered a challenge for pediatricians. Although most asthmatic patients are symptom-free with standard treatments, a small percentage of them suffer from uncontrolled persistent asthma. In these children, a multidisciplinary systematic assessment, including comorbidities, treatment-related issues, environmental exposures, and psychosocial factors is needed. The identification of modifiable factors is important to differentiate children with difficult asthma from those with true severe therapy-resistant asthma. Early intervention on modifiable factors for children with difficult asthma allows for better control of asthma without the need for invasive investigation and further escalation of treatment. Otherwise, addressing a correct diagnosis of true severe therapy-resistant asthma avoids diagnostic and therapeutic delays, allowing patients to benefit from using new and advanced biological therapies.
