THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:2715-2723. [PMID: 37245734 DOI: 10.1016/j.jaip.2023.05.025] [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: 02/28/2023] [Revised: 05/05/2023] [Accepted: 05/16/2023] [Indexed: 05/30/2023]
Abstract
BACKGROUND Biologic therapies such as mepolizumab and benralizumab offer treatment options for severe eosinophilic asthma (SEA), although long-term real-world data on their use are limited. OBJECTIVES To evaluate the impact of benralizumab and mepolizumab treatment among biologic-naive patients with SEA over 36 months and describe the incidence of super-response at 12 and 36 months, identifying potential predictive factors. METHODS We conducted a retrospective, single-center study of patients with SEA who were given mepolizumab or benralizumab from May 2017 to December 2019, and who completed 36 months of therapy. Baseline demographics, comorbidities, and medication use were described. Data on clinical outcomes, including maintenance oral corticosteroid (OCS) use, annual exacerbation rate (AER), mini Asthma Quality of Life Questionnaire, Asthma Control Questionnaire (ACQ-6), and eosinophil count were collected at baseline and at 12 and 36 months. Super-response was evaluated at 12 and 36 months. RESULTS A total of 81 patients were included. Maintenance OCS use significantly improved from baseline (5.3 mg/d) to 12 months (2.4 mg/d, P < .0001) and 36 months (0.6 mg/d; P < .0001). Annual exacerbation rate decreased from baseline (5.8) to 12 months (0.9; P < .0001) and 36 months (1.2; P < .0001). Mini Asthma Quality of Life Questionnaire, ACQ-6, and eosinophil count significantly improved from baseline to 12 and 36 months. Twenty-nine patients demonstrated super-response at 12 months. Compared with those without a super-response, these patients had better baseline AER (4.7 vs 6.5; P = .009), mini Asthma Quality of Life Questionnaire (3.41 vs 2.54; P = .002), and ACQ-6 (3.38 vs 4.06; P = .03) scores. Most maintained a super-response up to 36 months. CONCLUSIONS Mepolizumab and benralizumab are associated with significant improvements in OCS use, AER, and asthma control in real-world cohorts for up to 36 months, providing insight into long-term use for SEA.

Abstract
Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP) are chronic respiratory diseases. These two disorders often co-exist based on common anatomical, immunological, histopathological, and pathophysiological basis. Usually, asthma with comorbid CRSwNP is driven by type 2 (T2) inflammation which predisposes to more severe, often intractable, disease. In the past two decades, innovative technologies and detection techniques in combination with newly introduced targeted therapies helped shape our understanding of the immunological pathways underlying inflammatory airway diseases and to further identify several distinct clinical and inflammatory subsets to enhance the development of more effective personalized treatments. Presently, a number of targeted biologics has shown clinical efficacy in patients with refractory T2 airway inflammation, including anti-IgE (omalizumab), anti-IL-5 (mepolizumab, reslizumab)/anti-IL5R (benralizumab), anti-IL-4R-α (anti-IL-4/IL-13, dupilumab), and anti-TSLP (tezepelumab). In non-type-2 endotypes, no targeted biologics have consistently shown clinical efficacy so far. Presently, multiple therapeutical targets are being explored including cytokines, membrane molecules and intracellular signalling pathways to further expand current treatment options for severe asthma with and without comorbid CRSwNP. In this review, we discuss existing biologics, those under development and share some views on new horizons.

Exploring the Interaction between Fractional Exhaled Nitric Oxide and Biologic Treatment in Severe Asthma: A Systematic Review. Antioxidants (Basel) 2023; 12:antiox12020400. [PMID: 36829959 PMCID: PMC9952501 DOI: 10.3390/antiox12020400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2022] [Revised: 02/02/2023] [Accepted: 02/03/2023] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND Fractional exhaled nitric oxide (FeNO) is a biomarker of airway inflammation associated with airway hyper-responsiveness and type-2 inflammation. Its role in the management of severe asthmatic patients undergoing biologic treatment, as well as FeNO dynamics during biologic treatment, is largely unexplored. PURPOSE The aim was to evaluate published data contributing to the following areas: (1) FeNO as a predictive biomarker of response to biologic treatment; (2) the influence of biologic treatment in FeNO values; (3) FeNO as a biomarker for the prediction of exacerbations in patients treated with biologics. METHODS The systematic search was conducted on the Medline database through the Pubmed search engine, including all studies from 2009 to the present. RESULTS Higher baseline values of FeNO are associated with better clinical control in patients treated with omalizumab, dupilumab, and tezepelumab. FeNO dynamics during biologic treatment highlights a clear reduction in FeNO values in patients treated with anti-IL4/13 and anti-IL13, as well as in patients treated with tezepelumab. During the treatment, FeNO may help to predict clinical worsening and to differentiate eosinophilic from non-eosinophilic exacerbations. CONCLUSIONS Higher baseline FeNO levels appear to be associated with a greater benefit in terms of clinical control and reduction of exacerbation rate, while FeNO dynamics during biologic treatment remains a largely unexplored issue since few studies have investigated it as a primary outcome. FeNO remains detectable during biologic treatment, but its potential utility as a biomarker of clinical control is still unclear and represents an interesting research area to be developed.

Abstract
Asthma is a chronic inflammatory airway disease resulting in airflow obstruction, which in part can become irreversible to conventional therapies, defining the concept of airway remodeling. The introduction of biologics in severe asthma has led in some patients to the complete normalization of previously considered irreversible airflow obstruction. This highlights the need to distinguish a "fixed" airflow obstruction due to structural changes unresponsive to current therapies, from a "reversible" one as demonstrated by lung function normalization during biological therapies not previously obtained even with high-dose systemic glucocorticoids. The mechanisms by which exposure to environmental factors initiates the inflammatory responses that trigger airway remodeling are still incompletely understood. Alarmins represent epithelial-derived cytokines that initiate immunologic events leading to inflammatory airway remodeling. Biological therapies can improve airflow obstruction by addressing these airway inflammatory changes. In addition, biologics might prevent and possibly even revert "fixed" remodeling due to structural changes. Hence, it appears clinically important to separate the therapeutic effects (early and late) of biologics as a new paradigm to evaluate the effects of these drugs and future treatments on airway remodeling in severe asthma.

Abstract
Background Whether sex can influence the clinical response to biological treatment in patients with severe asthma has not been fully addressed. Aims and methods The aim of this study was to investigate in patients with severe asthma undergoing biological treatment the individual evolution of lung function measurements and patient-reported asthma control scores over a 12-month follow-up period, in relation to patients’ sex, in different age ranges. Second, the change in the administered dose of oral corticosteroids (OCS) before and after 12 months of treatment was investigated. Results 64 patients (58% female and 42% male) with a median age of 52 years were enrolled in the study. There were no relevant differences between sexes in terms of lung function, patient-reported asthma control, exacerbation rate and daily OCS dose within the study timeframe. A separate sub-analysis by biological treatment confirmed the same finding. Stratifying individuals by age, we showed that older men had lower lung function parameter values (forced expiratory volume in 1 s (FEV1) % predicted and FEV1/forced vital capacity index) than older women, whereas an opposite trend was observed in terms of Asthma Control Test score. No other relevant differences were detected after age stratification. Conclusion According to our findings, sex does not act as a determinant of treatment response to biologicals in people with severe asthma. Although to be confirmed in larger studies, our data suggest that neither sex nor age should limit biological treatment prescription, once the eligibility criteria for that therapy are satisfied. Sex does not seem to act as a determinant of treatment response to biologicals in severe asthma.

Abstract
BACKGROUND Severe asthma is a major cause of morbidity. Some patients may benefit from biological therapies. Most evaluations of these treatments are derived from randomised controlled trials (RCTs), but few patients are eligible for these trials. Studies involving more diverse groups of participants exist but there is a lack of precise pooled estimates. OBJECTIVE This systematic review aims to evaluate the real-world efficacy of recently and nearly licensed biological therapies for severe asthma to assess the generalisability of the RCT data. METHODS Clinical outcomes including exacerbation rate, oral corticosteroid (OCS) usage, forced expiratory volume in 1 second (FEV1 ) and fractional exhaled nitric oxide (FeNO) were examined. Studies were assessed for risk of bias using the Critical Appraisal Skills Programme (CASP) checklist tool. The certainty of evidence was assessed using GRADE. RESULTS A total of 21 studies examining biologicals in real-world settings were identified, they mostly focused on benralizumab and mepolizumab. The introduction of biologicals reduced the annualised exacerbation rate significantly by -3.79 (95% CI -4.53, -3.04), -3.17 (95% CI -3.74, -2.59) and -6.72 (95% CI -8.47, -4.97) with benralizumab, mepolizumab and reslizumab respectively. Likewise, improvements were observed in FEV1 (0.17 L 95% CI 0.11, 0.24) and FeNO (-14.23 ppb 95% CI -19.71, -8.75) following treatment with mepolizumab. After treatment with benralizumab there was an increase in FEV1 (0.21 L 95% CI 0.08, 0.34). CONCLUSIONS These data demonstrate that anti-IL5 biologicals may improve the clinical outcomes of patients with severe asthma in a clinic environment with similar effect sizes to RCTs. The data were mainly retrospective and unadjusted, so estimated effect sizes may not be reliable. More data is needed to acquire accurate effect estimates in different subpopulations of patients.

Abstract
OBJECTIVE The efficacy and safety of mepolizumab in patients with severe eosinophilic asthma in randomized controlled trials is well established. Following approval of mepolizumab as add-on therapy for severe eosinophilic asthma in multiple regions worldwide, it is now important to determine its impact in real-world settings in which patients are not subject to stringent eligibility criteria. This systematic literature review assessed published evidence of clinical outcomes, safety, and healthcare resource use among patients with severe asthma receiving mepolizumab in real-world settings. DATA SOURCES Searches were conducted in Embase, MEDLINE, and MEDLINE In-Process via Ovid. STUDY SELECTIONS Eligible studies were observational, and enrolled ≥10 patients with asthma who received mepolizumab 100 mg subcutaneously. Data extracted included annualized exacerbation rate, mean daily oral corticosteroid (OCS) dose, proportion of patients using OCS, several measures of lung function, patient-reported asthma control and health-related quality of life (HRQoL), safety, and economic burden. RESULTS Twenty-three articles (22 unique studies; 2,040 patients with severe asthma on mepolizumab) were identified. Mepolizumab use was associated with a reduction in annualized exacerbation rates (requiring OCS) of 54-97% (p < 0.05 in all studies), reduced mean/median daily OCS doses, and OCS discontinuation during follow-up (27-84% of patients). Improvements in lung function, asthma control, and HRQoL were also observed. The most commonly reported adverse events included headache and arthralgia; discontinuation of mepolizumab due to adverse events occurred in 0-10.6% of patients. CONCLUSION Findings show that patients with severe asthma consistently demonstrate clinically relevant benefits with mepolizumab treatment in a real-world setting.

Abstract
Background: The fractional exhaled nitric oxide (FENO) test is a point-of-care test that is used in the assessment of asthma. Objective: To provide evidence-based clinical guidance on whether FENO testing is indicated to optimize asthma treatment in patients with asthma in whom treatment is being considered. Methods: An international, multidisciplinary panel of experts was convened to form a consensus document regarding a single question relevant to the use of FENO. The question was selected from three potential questions based on the greatest perceived impact on clinical practice and the unmet need for evidence-based answers related to this question. The panel performed systematic reviews of published randomized controlled trials between 2004 and 2019 and followed the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) evidence-to-decision framework to develop recommendations. All panel members evaluated and approved the recommendations. Main Results: After considering the overall low quality of the evidence, the panel made a conditional recommendation for FENO-based care. In patients with asthma in whom treatment is being considered, we suggest that FENO is beneficial and should be used in addition to usual care. This judgment is based on a balance of effects that probably favors the intervention; the moderate costs and availability of resources, which probably favors the intervention; and the perceived acceptability and feasibility of the intervention in daily practice. Conclusions: Clinicians should consider this recommendation to measure FENO in patients with asthma in whom treatment is being considered based on current best available evidence.

Abstract
Secondary adrenal insufficiency (AI) occurs as the result of any process that disrupts normal hypothalamic and/or anterior pituitary function and causes a decrease in the secretion of steroid hormones from the adrenal cortex. The most common cause of secondary AI is exogenous corticosteroid therapy administered at supraphysiologic dosages for ≥ 1 month. AI caused by oral corticosteroids (OCS) is not well-recognized or commonly diagnosed but is often associated with reduced well-being and can be life-threatening in the event of an adrenal crisis. Corticosteroid use is common in respiratory diseases, and asthma is a representative condition that illustrates the potential challenges and opportunities related to corticosteroid-sparing therapies. For individuals with severe asthma (approximately 5%-10% of all cases), reduction or elimination of maintenance OCS without loss of control can now be accomplished with biologic therapies targeting inflammatory mediators. However, the optimal strategy to ensure early identification and treatment of AI and safe OCS withdrawal in routine clinical practice remains to be defined. Many studies with biologics have involved short evaluation periods and small sample sizes; in addition, cautious approaches to OCS tapering in studies with a placebo arm, coupled with inconsistent monitoring for AI, have contributed to the lack of clarity. If the goal is to greatly reduce and, where possible, eliminate long-term OCS use in severe asthma through the increasing adoption of biologic treatments, there is an urgent need for clinical trials that address both the speed of OCS withdrawal and how to monitor for AI.

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.

Real-World Effectiveness of Mepolizumab in Severe Eosinophilic Asthma: A Systematic Review and Meta-analysis. Clin Ther 2021; 43:e192-e208. [PMID: 33962763 DOI: 10.1016/j.clinthera.2021.03.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 03/04/2021] [Accepted: 03/29/2021] [Indexed: 12/29/2022]
Abstract
PURPOSE Mepolizumab is a human monoclonal antibody against interleukin 5 (IL-5) used to treat severe eosinophilic asthma. Several studies have evaluated the effectiveness of mepolizumab in the real world. We conducted a systematic review and meta-analysis in the context of heterogeneity among patients, clinicians, and treatment regimens to study the effectiveness of mepolizumab in the real world. METHODS We searched the PubMed and Embase databases for real-world studies on severe asthma treatment with mepolizumab as of June 30, 2020. Exacerbations, asthma-related hospitalizations, forced expiratory volume in 1 second (FEV1), Asthma Control Questionnaire (ACQ) or Asthma Control Test (ACT), corticosteroid use, peripheral blood eosinophil counts, and the fraction of exhaled nitric oxide were selected as indicators to evaluate the effectiveness. Standardized mean differences by the Cohen method and mean differences were chosen as indicators of effect size. Cohen d values of 0.2, 0.5, and 0.8 are considered as small, medium, and large effects, respectively. We used the Dersimonian-Laird random-effect model to quantify pooled effectiveness estimates. FINDINGS A total of 1457 patients from 13 studies were included in this review. At all time points, mepolizumab was associated with reductions in exacerbations (2.92 and 2.73 events per patient per year fewer at 6 and 12 months, respectively) and hospitalizations (0.36 events per patient per year fewer at 12 months); improvements in asthma control (ACQ scores reductions of 1.32 and 1.03 at 6 and 12 months, respectively; ACT scores increase of 6.52 at 6-12 months); slight improvements in pulmonary function (FEV1 increase of 0.23 L at 1-3 months and 6-12 months, respectively); reductions in oral corticosteroid use (9.02- and 7.68-mg decrease at 6 and 12 months, respectively); and reductions in peripheral blood eosinophil counts (decreases of 559.11 cells/μL and 599.17 cells/μL at 1-3 months and 6-12 months, respectively) and fraction of exhaled nitric oxide (13-ppb reduction at 6-12 months). IMPLICATIONS Our study suggests that mepolizumab is associated with improvements in several clinically meaningful real-world outcomes. This study is a supplement to and extension of the efficacy of randomized controlled trials of mepolizumab. (Clin Ther. 2021;XX:XXX-XXX) © 2021 Elsevier HS Journals, Inc.

Abstract
OBJECTIVE Add-on therapy with monoclonal antibodies is the recommended therapy for severe asthmatic patients refractory to maintenance treatment. In randomized control trials, mepolizumab reduced the number of exacerbations, the need of oral corticosteroids (OCS), increased asthma control, and lung function in a population of uncontrolled severe eosinophilic asthmatic patients. In this piece of work, we aimed to assess mepolizumab efficacy and safety in a cohort of patients with severe eosinophilic asthma in real-life conditions. METHODS A retrospective study was carried out at eight hospitals from Asturias (Spain). The sample included patients treated with mepolizumab from 1 January 2016 to 31 March 2019. Demographic and clinical variables were collected, including OCS use, asthma control, lung function, and exacerbation rate. RESULTS Sixty-nine patients (72% women) with mean age 56 ± 13 years were included. Annual exacerbation rate decreased from 4.7 (SD 3.7) to 1.3 (SD 2.5) (p < 0.001). The number of patients requiring OCS treatment decreased from 25 patients (36%, mean prednisone dose = 18 mg/day) to 13 patients (19%, mean prednisone dose = 9 mg/day) (p < 0.001). Twelve patients (48%) stopped OCS treatment. Forced expired volume in one second (FEV1) as percentage increased from 68% (SD 20) to 76% (SD 21) (p < 0.001). Fifty-six patients (81%) were considered responders to mepolizumab. No serious adverse events were detected during the study period. CONCLUSIONS Overall, this study demonstrates mepolizumab efficacy and safety in a cohort of patients with uncontrolled severe eosinophilic asthma in routine clinical practice.

Mepolizumab and Oral Corticosteroid Stewardship: Data from the Australian Mepolizumab Registry. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:2715-2724.e5. [PMID: 33545399 DOI: 10.1016/j.jaip.2021.01.028] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 01/13/2021] [Accepted: 01/14/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Oral corticosteroids (OCS) carry serious health risks. Innovative treatment options are required to reduce excessive exposure and promote OCS stewardship. OBJECTIVES This study evaluated the trajectories of OCS exposure (prednisolone-equivalent) in patients with severe eosinophilic asthma before and after starting mepolizumab and the predictors of becoming OCS free after 6 months of mepolizumab therapy. METHODS This real-world observational study included 309 patients from the Australian Mepolizumab Registry who were followed up for 1 year (n = 225). RESULTS Patients had a median age of 60 (interquartile range: 50, 68) years, and 58% were female. At baseline, 48% used maintenance OCS, 96% had ≥1 OCS burst, and 68% had received ≥1 g of OCS in the previous year. After commencing mepolizumab, only 55% of those initially on maintenance OCS remained on this treatment by 12 months. Maintenance OCS dose reduced from median 10 (5.0, 12.5) mg/day at baseline to 2 (0, 7.0) mg/day at 12 months (P < .001). Likewise, proportions of patients receiving OCS bursts in the previous year reduced from 96% at baseline to 50% at 12 months (P < .001). Overall, 137 (48%) patients required OCS (maintenance/burst) after 6 months' mepolizumab therapy. Becoming OCS free was predicted by a lower body mass index (odds ratio: 0.925; 95% confidence interval: 0.872-0.981), late-onset asthma (1.027; 1.006-1.048), a lower Asthma Control Test score (1.111; 0.011-1.220), and not receiving maintenance OCS therapy at baseline (0.095; 0.040-0.227). CONCLUSION Mepolizumab led to a significant and sustained reduction in OCS dependence in patients with severe eosinophilic asthma. This study supports the OCS-sparing effect of mepolizumab and highlights the pivotal role of mepolizumab in OCS stewardship initiatives.

J Asthma Allergy 2020; 13:689-699. [PMID: 33364788 PMCID: PMC7751313 DOI: 10.2147/jaa.s275944] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 11/21/2020] [Indexed: 12/23/2022] Open
Abstract
Background Patients with severe asthma often require oral corticosteroid (OCS) treatment. Clinical trials have demonstrated that mepolizumab can reduce OCS dependence, but real-world data are limited. Objective To evaluate the impact of mepolizumab on OCS use, asthma exacerbations, and asthma exacerbation-related costs in a real-world setting. Methods This retrospective cohort study (GSK ID: 209642; HO-19-19597) analyzed data from the MarketScan® Commercial database (identification period: November 2015–September 2017). Patients were ≥12 years old at mepolizumab initiation (index date), had a baseline asthma diagnosis, and received ≥2 mepolizumab administrations in the first 6 months of follow-up. OCS use, asthma exacerbation rate, and asthma exacerbation-related costs were assessed in the 12-months before (baseline) and 12-months after (follow-up) mepolizumab initiation. Results Mepolizumab was associated with a 14.7% reduction in the proportion of patients with ≥1 OCS claim from baseline to follow-up (93.4% vs 79.7%; P<0.001). The mean numbers of OCS claims/patient and OCS bursts (≥20 mg prednisone equivalents for 3‒28 days) between baseline and follow-up were also reduced by 29.1% (P<0.001) and 36.8% (P<0.001), respectively. Reductions in chronic OCS use were demonstrated during follow-up in patients with baseline mean OCS dose ≥5mg and those with a mean OCS dose ≥10mg 90 days before index; the proportion of patients with no OCS use also increased from 6.6% to 20.3% between baseline and follow-up. Conclusion Our findings demonstrate that mepolizumab therapy is associated with reduced OCS use in patients treated in a real-world setting, potentially mitigating adverse health sequelae caused by OCS use in these patients.

Oral corticosteroid sparing effects of anti-IL5/ anti-IL5 receptor treatment after 2 years of treatment. Respir Med 2020; 176:106260. [PMID: 33264712 DOI: 10.1016/j.rmed.2020.106260] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 11/18/2020] [Accepted: 11/23/2020] [Indexed: 12/21/2022]
Abstract
INTRODUCTION Clinical trials have shown oral corticosteroid (OCS) sparing effects of anti-IL5/anti-IL5-receptor treatments. The generalisability of these clinical trials may be limited, due to the rigid inclusion and exclusion criteria, and the short tapering duration. Real-world evidence is needed to bridge the gap between the clinical trials and the clinical practice. With this study we present real-life data on the OCS sparing effects of anti-IL5/anti-IL5-receptor treatments after 12 and 24 months of treatment. METHODS Severe, eosinophilic asthma patients treated with mepolizumab, reslizumab or benralizumab for 24 months were included in this observational study. Data on OCS-dose, FEV1, ACT/ACQ score and blood eosinophils were obtained from the patients records before anti-IL5/anti-IL5-receptor treatment, and after 12 and 24 months of treatment. RESULTS At baseline 75% of patients were on daily OCS. This number was reduced to 50% after one year of treatment, p < 0.001, and 28% after two years of treatment, p < 0.001. Within the group on daily OCS the median daily dose was reduced from 10 mg of Prednisolone at baseline (IQR 5-20) to 3.75 mg Prednisolone (IQR 0-10) after 12 months, and 0 mg Prednisolone (IQR 0-7.5) after 24 months, p < 0.001. CONCLUSIONS The findings in this study add to the generalisability of the clinical studies, showing significant OCS sparing effects of anti-IL5/anti-IL5-receptor treatment in a real-life setting. Furthermore, these findings add to the understanding of the long-term effects of anti-IL5/anti-IL5-receptor treatment, showing an even further and persistent OCS reduction after two years of treatment.

Abstract
Background Data on mepolizumab in patients with severe eosinophilic asthma (EA) and comorbidities are needed to assess whether randomized controlled trial results are applicable in the real world. Objective To evaluate real-life effectiveness and the presence/absence of predictors of treatment response in patients with one or more comorbidities (nasal polyps, allergic rhinitis, gastro-esophageal reflux disease, nonallergic rhinitis with eosinophilia syndrome, obesity, bronchiectasis) who received mepolizumab (MEPO) for the treatment of severe EA. Methods We performed a single-center retrospective study in patients with severe asthma and presence of comorbidities treated with mepolizumab at the respiratory outpatient clinic, Policlinico-Vittorio Emanuele, Catania, Italy. Health records of 31 severe asthmatic patients were retrieved and analyzed. Asthma control test (ACT) score, blood eosinophil count, forced expiratory volume in 1 s (FEV1), FEV1% of predicted and FEV1/FVC (Forced Vital Capacity) ratio, oral corticosteroid (OCS) dosage, and exacerbations were recorded at baseline (T0), after 3 (T1), 6 (T3), 9 (T6), and 12 months (T12). Clinical response was defined when 3 of these 4 criteria were fulfilled: i) 30% exacerbation decrease; ii) 80% blood eosinophilia reduction; iii) 3 point ACT increase; iv) FEV1 increase ≥200 mL. Results 83.87% of patients were classified as responsive to MEPO treatment. Substantial depletion of the blood eosinophils (>80%) was found in 87.1% of patients, FEV1 > 200 mL was seen in 54.84% of patients, a 3-point ACT improvement from baseline was recorded in 80.65% 25 of patients and a 30% reduction of exacerbations rates was seen in 96.77% of patients. Moreover, the majority 38.71% of patients met 3/4 parameters after 12 months. Neither the comorbidities nor other characteristics (sex, BMI, age, smoking) influenced treatment response. Conclusions MEPO in patients with severe EA is effective regardless of the presence of comorbidities.

Abstract
BACKGROUND Mepolizumab was effective in several randomized clinical trials (RCTs) in patients with severe eosinophilic asthma, but evidence for symptom control in a real-world population is scarce. OBJECTIVE To assess asthma symptom control, lung function, use of oral corticosteroids, and biomarkers after mepolizumab initiation in real-world clinical practice. METHODS Thirty-five adult patients with severe eosinophilic asthma and inadequate asthma symptom control, including former smokers and patients with cardiac disease, were enrolled in a prospective single-arm real-world study. Asthma control tests (ACT), exacerbations, spirometry (pre-bronchodilator forced expiratory volume in 1 s [FEV1]), and oral corticosteroid doses were documented. Further assessments included peripheral blood eosinophil counts and adverse events. RESULTS After mepolizumab initiation asthma symptom control was significantly improved with the median ACT score of 12.5 at baseline (interquartile range [IQR ]10.5-19.5) rising to 19 (15-22.5) after 4 weeks. The improvement was maintained throughout the observation period of 20 weeks. Likewise, exacerbations were reduced. After 8 weeks of mepolizumab daily OCS doses were reduced from 6.25 mg daily (0-20) at baseline to 2.5 mg daily (0-11.9) at week 8 (P < 0.001). FEV1 remained generally unchanged during the course of the study. Eosinophil counts rapidly declined and remained at a low level during the observation period. No new safety signals were observed in this study. CONCLUSION Mepolizumab improved asthma symptom control and had a steroid-sparing effect. Efficacy in this real-world study was comparable to RCTs, despite a history of smoking and comorbidities in many of the patients included.

Abstract
By selectively targeting specific steps of the immune inflammation cascade, biologic drugs for severe asthma have substantially contributed to increase the standard of care, to reduce drug-related morbidity. and most importantly to ameliorate patients' quality of life. Upcoming molecules are going to provide a chance for severe phenotypes besides Th2 high through the interaction with epithelial and innate immunity. Some practical aspects including optimal treatment duration, the possibility of a dose treatment modulation, the place and relevance of ICS in best responders are still under debate. Long-term safety, especially when interacting with innate immunity needs to be further investigated.

Abstract
Background Mepolizumab was available in France as part of an early access programme for patients with severe eosinophilic asthma (nominative autorisation temporaire d'utilisation [temporary use authorisation] (nATU)) before its commercialisation. This study aimed to characterise patients who received mepolizumab in the nATU. Methods This retrospective, observational study analysed data from the hospital medical records of patients up to 24 months after treatment initiation. Study objectives were to describe patient baseline characteristics, the evolution of disease severity and treatment modifications during follow-up; safety was also investigated. Findings Overall, 146 patients who received ≥1 dose of mepolizumab were included. At inclusion, patients had a mean age of 58.2 years with a mean severe asthma duration of 13.4 years, and 37.0% had respiratory allergies. Patients experienced, on average, 5.8 exacerbations per patient per year at baseline, 0.6 and 0.5 of which required hospitalisation and emergency department visits, respectively. These values improved to 0.6, 0.1 and 0.1 exacerbations per patient per year, respectively, at 24 months of follow-up. Most patients (92.8%) were using oral corticosteroids at baseline, compared with 34.7% by 24 months of follow-up. Moreover, mean blood eosinophil counts improved from 722 cells·µL−1 at baseline to 92 cells·µL−1 at 24 months of follow-up; lung function and asthma control followed a similar trend. Interpretation Results confirm findings from clinical trials, demonstrating that mepolizumab is associated with important improvements in several clinically meaningful outcomes and has a favourable safety profile in a population with severe eosinophilic asthma, outside of the controlled environment of a clinical trial.

Abstract
INTRODUCTION Interleukin-5 (IL-5) is the principal cytokine regulating eosinophil growth, differentiation, activation, and expression. It is a specific target of mepolizumab, an anti-IL-5 monoclonal antibody used in the treatment of severe eosinophilic asthma. This new drug can improve symptoms, reduce asthma exacerbations and steroid use. Few data are available on its efficacy for nasal symptoms. OBJECTIVE To describe the all-round clinical impact of mepolizumab in a real-life setting, evaluating the efficacy and safety of the drug in severe eosinophilic asthma patients. POPULATION AND METHODS We retrospectively collected the clinical and functional data on 27 patients (16 males) affected with severe eosinophilic asthma, diagnosed at the Siena Regional Referral Centre and monitored for 6 months. Clinical, immunological, and functional data at baseline and follow-up were entered in a database together with comorbidities, number of exacerbations, steroid treatment, multiple-flow exhaled nitric oxide, and validated questionnaires. RESULTS A significant reduction in asthma exacerbations was observed in all patients after 6 months of the biological therapy (p = 0.0009), and 4/6 patients discontinued chronic oral steroids. A significant improvement in ACT, FEV1, SNOT22, and alveolar nitric oxide was observed after 1 month of mepolizumab (p = 0.003, p = 0.007, p = 0.047, and p = 0.019, respectively) and maintained after 6 months of treatment. After 6 months, FeNO 50 was reduced as well (p = 0.030). Mepolizumab was very well tolerated, and no major side effects were observed. CONCLUSIONS Our study suggests that mepolizumab is effective in improving control of asthma, lung function parameters, exhaled biomarkers, and nasal symptoms in patients with severe eosinophilic asthma.

Abstract
Severe asthma is a high-burden disease. Real-world data on mepolizumab in patients with severe eosinophilic asthma is needed to assess whether the data from randomised controlled trials are applicable in a broader population.The Australian Mepolizumab Registry (AMR) was established with an aim to assess the use, effectiveness and safety of mepolizumab for severe eosinophilic asthma in Australia.Patients (n=309) with severe eosinophilic asthma (median age 60 years, 58% female) commenced mepolizumab. They had poor symptom control (median Asthma Control Questionnaire (ACQ)-5 score of 3.4), frequent exacerbations (median three courses of oral corticosteroids (OCS) in the previous 12 months), and 47% required daily OCS. Median baseline peripheral blood eosinophil level was 590 cells·µL-1 Comorbidities were common: allergic rhinitis 63%, gastro-oesophageal reflux disease 52%, obesity 46%, nasal polyps 34%.Mepolizumab treatment reduced exacerbations requiring OCS compared with the previous year (annualised rate ratio 0.34 (95% CI 0.29-0.41); p<0.001) and hospitalisations (rate ratio 0.46 (95% CI 0.33-0.63); p<0.001). Treatment improved symptom control (median ACQ-5 reduced by 2.0 at 6 months), quality of life and lung function. Higher blood eosinophil levels (p=0.003) and later age of asthma onset (p=0.028) predicted a better ACQ-5 response to mepolizumab, whilst being male (p=0.031) or having body mass index ≥30 (p=0.043) predicted a lesser response. Super-responders (upper 25% of ACQ-5 responders, n=61, 24%) had a higher T2 disease burden and fewer comorbidities at baseline.Mepolizumab therapy effectively reduces the significant and long-standing disease burden faced by patients with severe eosinophilic asthma in a real-world setting.

Abstract
Introduction: Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating disease of the central nervous system affecting primarily the spinal cord and optic nerves. Most NMOSD patients are seropositive for immunoglobulin G autoantibodies against astrocyte water channel aquaporin-4, called AQP4-IgG, which cause astrocyte injury leading to demyelination and neurological impairment. Current therapy for AQP4-IgG seropositive NMOSD includes immunosuppression, B cell depletion, and plasma exchange. Newer therapies target complement, CD19 and IL-6 receptors.Areas covered: This review covers early-stage pre-clinical therapeutic approaches for seropositive NMOSD. Targets include pathogenic AQP4-IgG autoantibodies and their binding to AQP4, complement-dependent and cell-mediated cytotoxicity, blood-brain barrier, remyelination and immune effector and regulatory cells, with treatment modalities including small molecules, biologics, and cells.Expert opinion: Though newer NMOSD therapies appear to have increased efficacy in reducing relapse rate and neurological deficit, increasingly targeted therapies could benefit NMOSD patients with ongoing relapses and could potentially be superior in efficacy and safety. Of the various early-stage therapeutic approaches, IgG inactivating enzymes, aquaporumab blocking antibodies, drugs targeting early components of the classical complement system, complement regulator-targeted drugs, and Fc-based multimers are of interest. Curative strategies, perhaps involving AQP4 tolerization, remain intriguing future possibilities.

[PMID: 32070330 PMCID: PMC7029476 DOI: 10.1186/s12931-020-1318-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2019] [Accepted: 02/10/2020] [Indexed: 02/08/2023] Open
Abstract
Objective We aimed to identify the prevalence and distribution patterns of allergens among Chinese children with asthma/asthma-like symptoms (ALS). Methods A total of 3479 children with asthma/ALS were enrolled. Skin prick test (SPT) was used to test the allergen-specific IgE. We analysed allergens prevalence and distribution, and its relationship with demographic characteristics. Results Aeroallergens prevalence was higher than that of food allergens (p < 10− 4). Boys had higher aeroallergens prevalence than that in girls (p < 10− 4). Significant difference of aeroallergens prevalence among cases with different parental allergy history was observed (p < 10− 4). Age was positively associated with aeroallergens prevalence before the age of 11.5 (P < 10− 4), particularly before the age of 2.42 (P < 10− 4). Age was negatively associated with aeroallergens prevalence after the age of 11.5 (P = 0.021). Age was negatively associated with food allergens prevalence before the age of 3.42 (P < 10− 4). Age was associated with the intensity of dermatophagoides farinae (DF)/house dust mite (HDM) allergens (P < 10− 4). Age was negatively associated with the intensity of shrimp, and crab allergens before the age of 3.3 and 3.3, respectively (P = 0.012, < 10− 4). Boys had higher intensity of DF and HDM allergens than that in girls (P < 10− 4, P < 10− 4). Significant differences of the intensity of DF and HDM allergens among groups with different parental allergy history were noted (P < 10− 4, P < 10− 4). Conclusions Boys and parental allergy history were associated with higher prevalence and intenstity of aeroallergens. Age was positively and negatively associated with aeroallergens prevalence before and after the age of 11.5, respectively. Age was negatively associated with food allergens prevalence before the age of 3.42.
