Clinical Remission Criteria and Serum Levels of Type 2 Inflammation Mediators during 24 Weeks of Treatment with the Anti-IL-5 Drug Mepolizumab in Patients with T2-High Severe Asthma. Diagnostics (Basel) 2024; 14:1345. [PMID: 39001236 PMCID: PMC11240777 DOI: 10.3390/diagnostics14131345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 06/19/2024] [Accepted: 06/21/2024] [Indexed: 07/16/2024] Open
Abstract
Anti-interleukin (IL) 5 is an effective treatment modality for inhibiting eosinophilic inflammation in patients with T2-high severe asthma. The aim of this study was to determine the clinical efficacy and serum levels of type 2 inflammatory mediators during 24 weeks of mepolizumab treatment in patients with T2-high severe asthma. Eighteen patients with T2-high severe asthma were enrolled in this study. All patients received 100 mg of mepolizumab subcutaneously every 4 weeks and were retested at 4, 12, and 24 weeks. A clinical examination, asthma control test (ACT), and spirometry were performed; fractional exhaled nitric oxide (FeNO) levels were evaluated; and blood samples were drawn at every visit. Type 2 inflammation mediator levels were measured using enzyme-linked immunosorbent assay (ELISA). The blood eosinophil level significantly decreased, the ACT score and FEV1 increased after 4 weeks of mepolizumab treatment with the same tendency after 12 and 24 weeks (p < 0.05), and the FeNO level did not change (p > 0.05). A total of 27.8% of patients reached clinical remission criteria after 24 weeks of mepolizumab treatment. IL-33 and eotaxin significantly increased (p < 0.05) while IL-5, IL-13, thymic stromal lymphopoietin (TSLP), soluble IL-5 receptor subunit alpha (sIL-5Rα), and soluble high-affinity immunoglobulin E receptor (sFcεRI) decreased, with the same tendency after 12 and 24 weeks (p < 0.05). The serum levels of immunoglobulin (Ig) E and IL-4 and IL-25 levels did not change during mepolizumab treatment compared to baseline (p > 0.05). In conclusion, treatment with mepolizumab over 24 weeks improved lung function and asthma control in T2-high severe asthma patients, with nearly one-third achieving clinical remission criteria, and affected the balance of type 2 inflammatory mediators.

Cilli A, Uzer F, Ozbey G. Clinical remission maintained and improved over time in patients with severe asthma treated with omalizumab. J Asthma 2024:1-8. [PMID: 38805393 DOI: 10.1080/02770903.2024.2361777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/26/2024] [Indexed: 05/30/2024]
Abstract
BACKGROUND Clinical remission has recently been proposed as a possible treatment goal even in severe asthma. In this real-world study, we aimed to assess the achievement rate and predictive factors of clinical remission using omalizumab in patients with severe asthma. METHODS This retrospective observational study included patients with severe asthma initiated with omalizumab therapy and recruited from the asthma clinic of the Akdeniz University Hospital, Turkey. Clinical remission was defined as patients who received no oral corticosteroid (OCS) therapy; showed no exacerbations; showed an asthma control questionnaire score of ≤ 1, asthma control test (ACT) of ≥ 20, or both and, FEV1 of ≥ 80% predicted. RESULTS A total of 58 patients were included in the study, with an average age of 56.4 ± 13.6 years. The mean duration of asthma was 23.5 ± 11.8 years and the mean duration of omalizumab treatment was 80.05 ± 35.04 months. Clinical remission rates were 25.9% in the first and second year, 34.0% in the third year, 34.1% in the fourth year and 47.4% in the fifth year. Pre-omalizumab ACT, FEV1 (%) and OCS use were significantly higher in patients with clinical remission at 1 year. Logistic regression analyses showed that none of the factors predicted clinical remission. CONCLUSION Omalizumab has the potential to induce disease remission in a significant proportion of people with severe asthma, and this is maintained and improved over time.

Abstract
OBJECTIVE Patients with severe eosinophilic asthma experience high risk of exacerbations and reduced quality of life. Benralizumab, a monoclonal antibody binding to IL-5 receptor α subunit, is an approved drug for its treatment. The objective was to describe clinical remission after benralizumab prescription in routine clinical practice. METHODS Retrospective multicenter study with data from four hospitals in Valencian Community (Spain) with asthma units between 2019 and 2020. Data was gathered at baseline and after 12 months. We considered clinical remission after 1 year if the patient remained without exacerbations and use of systemic corticosteroids and with good clinical control and normal lung function. RESULTS Data from 139 patients was gathered. At the 12-month follow-up, 44.1% were in clinical remission, since 84.0%, 77.5%, 51.0% and 95.5% of patients did not experience exacerbations, had total asthma control test score of ≥20, prebronchodilator FEV1 of ≥80% and did not use systemic corticosteroids. A significant reduction of long-acting muscarinic antagonists (p = 0.0001), leukotriene receptor antagonists (p = 0.0326), oral corticosteroids (p < 0.0001) and short-acting beta agonists (p = 0.0499) was observed. Baseline factors with greatest individual influence on clinical remission were employment situation, tobacco use, comorbidity number, eosinophil value, number of exacerbations, FEV1, emergency visit number, and ACT, MiniAQLQ and TAI scores. Final analysis of multiple logistic regression indicated that having baseline FEV1 value below 80% increases remission chance 9.7 times a year compared to FEV1 >80%. CONCLUSION Clinical remission after treatment with benralizumab is achievable in a high percentage of patients with severe asthma eosinophilia not controlled in real life.

Abstract
The long-term goal of asthma management is to achieve disease control, comprising the assessment of 2 main domains: (1) symptom control and (2) future risk of adverse outcomes. Decades of progress in asthma management have correlated with increasingly ambitious disease control targets. Moreover, the introduction of precision medicines, such as biologics, has further expanded the limits of what can be achieved in terms of disease control. It is now believed that clinical remission, a term rarely associated with asthma, may be an achievable treatment goal. An expert framework published in 2020 took the first step toward developing a commonly accepted definition of clinical remission in asthma. However, there remains a widespread discussion about the clinical parameters and thresholds that should be included in a standardized definition of clinical remission. This review aims to discuss on-treatment clinical remission as an aspirational outcome in asthma management, drawing on experiences from other chronic diseases where remission has long been a goal. We also highlight the integral role of shared decision-making between patients and health care professionals and the need for a common understanding of the individual patient journey to remission as foundational elements in reducing disease burden and improving outcomes for patients with asthma.

Abstract
Purpose Severe eosinophilic asthma (SEA) patients often present overlapping inflammatory features rendering them eligible for multiple biologic therapies; switching biologic treatment is a strategy adopted to optimize asthma control when patients show partial or no response to previous biologics. Patients and Methods ANANKE is a retrospective, multicenter Italian study (NCT04272463). Here, we outline the characteristics and long-term clinical outcomes in naïve-to-biologics and biologics-experienced patients treated with benralizumab for up to 96 weeks. Bio-experienced patients were split into omalizumab and mepolizumab subsets according to the type of biologic previously used. Results A total of 124 (76.5%) naïve and 38 (23.5%) bio-experienced patients were evaluated at index date; 13 patients (34.2%) switched from mepolizumab, 21 patients (55.3%) switched from omalizumab, and four patients (10.5%) received both biologics. The mepolizumab subset was characterized by the longest SEA duration (median of 4.6 years), the highest prevalence of chronic rhinosinusitis with nasal polyposis (CRSwNP) (76.5%), and the greatest oral corticosteroid (OCS) daily dosage (median of 25 mg prednisone equivalent). The omalizumab group showed the highest severe annual exacerbation rate (AER) (1.70). At 96 weeks, treatment with benralizumab reduced any and severe AER by more than 87% and 94%, respectively, across all groups. Lung function was overall preserved, with major improvements observed in the mepolizumab group, which also revealed a 100% drop of the median OCS dose. Asthma Control Test (ACT) score improved in the naïve group while its increment was more variable in bio-experienced patients; among these, a marked difference was noticed between omalizumab and mepolizumab subsets (median ACT score of 23.5 and 18, respectively). Conclusion Benralizumab promotes durable and profound clinical benefits in naïve and bio-experienced groups, indicating that a nearly complete depletion of eosinophils is highly beneficial in the control of SEA, independently of previous biologic use.

Effect of Azithromycin on Asthma Remission in Adults With Persistent Uncontrolled Asthma: A Secondary Analysis of a Randomized, Double-Anonymized, Placebo-Controlled Trial. Chest 2024:S0012-3692(24)00284-8. [PMID: 38431051 DOI: 10.1016/j.chest.2024.02.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/20/2024] [Accepted: 02/22/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Asthma remission is a potential treatment goal. RESEARCH QUESTION Does adding azithromycin to standard therapy in patients with persistent uncontrolled asthma induce remission compared with placebo? STUDY DESIGN AND METHODS This secondary analysis used data from the Asthma and Macrolides: the Azithromycin Efficacy and Safety (AMAZES) clinical trial-a double-anonymized placebo-controlled trial that evaluated the safety and efficacy of azithromycin on asthma exacerbations. The primary remission definition (referred to as clinical remission) was zero exacerbations and zero oral corticosteroids during the previous 6 months evaluated at 12 months and a 5-item Asthma Control Questionnaire score ≤ 1 at 12 months. Secondary remission definitions included clinical remission plus lung function criteria (postbronchodilator FEV1 ≥ 80% or postbronchodilator FEV1 ≤ 5% decline from baseline) and complete remission (sputum eosinophil count < 3% plus the aforementioned criteria). Sensitivity analyses explored the robustness of primary and secondary remission definitions. The predictors of clinical remission were identified. RESULTS A total of 335 participants (41.5% male; median age, 61.01 years; quartile 1-3, 51.03-68.73) who completed the 12-month treatment period were included in the analysis. Twelve months of treatment with azithromycin induced asthma remission in a subgroup of patients, and a significantly higher proportion in the azithromycin arm achieved both clinical remission (50.6% vs 38.9%; P = .032) and clinical remission plus lung function criteria (50.8% vs 37.1%; P = .029) compared with placebo, respectively. In addition, a higher proportion of the azithromycin group achieved complete remission (23% vs 13.7%; P = .058). Sensitivity analyses supported these findings. Baseline factors (eg, better asthma-related quality of life, absence of oral corticosteroid burst in the previous year) predicted the odds of achieving clinical remission. Azithromycin induced remission in both eosinophilic and noneosinophilic asthma. INTERPRETATION In this study, adults with persistent symptomatic asthma achieved a higher remission rate when treated with azithromycin. Remission on treatment may be an achievable treatment target in moderate/severe asthma, and future studies should consider remission as an outcome measure.

Abstract
BACKGROUND The concept of remission on biological treatment has been suggested as a therapeutic target for patients with severe asthma, composed of 1. no chronic use of systemic steroids, 2. no exacerbations, 3. minimal symptoms, and 4. optimized lung function, for a significant time. However, the criteria for remission are not clearly defined. OBJECTIVE Our objective was to compare different criteria for remission in subjects receiving biologicals for severe asthma. METHODS A cross-sectional study of adult subjects who receive a stable regimen of a biological for severe asthma for at least 6-months. We compared the proportion of subjects who fulfilled different specific criteria in the four domains, as well as those who achieved different composite outcome measures of clinical remission. RESULTS Of 39 subjects, 28 were females (71.8%), mean age 60.4. Twelve were current or past smokers (30.8%). Twelve had prior different biological treatment (30.8%), and 3/39 had more than one previous treatment (7.7%). Current biological included mepolizumab 12/39 (30.8%), dupilumab 11/39 (28.2%), benralizumab 10/39 (25.6%), omalizumab 5/39 (12.8%), reslizumab 1/39 (2.6%). Different specific criteria were achieved in 39-80% of subjects, being highest for no chronic steroid use and lowest for symptoms control and lung function. Overall remission was obtained by 20-41%, depending on definition, with significant variability in agreement between different sets of remission criteria (Cohen's kappa 0.33-0.89). CONCLUSION Clinical remission is achievable in real-world severe asthmatics on biological therapies. The core criteria for remission should be better defined.

Eosinophilic Patterns in Patients with Seasonal Allergy Affected by Bronchial Asthma and Rhinitis/Rhinosinusitis: Efficacy of Benralizumab in Patients with the Persistent Pattern. J Clin Med 2024; 13:754.

Abstract
BACKGROUND Eosinophilia can be influenced by multiple factors. This study aims to set a protocol for monitoring blood absolute eosinophil count (AEC) in patients with seasonal allergy affected by bronchial asthma (BA), allergic rhinitis (AR), or chronic rhinosinusitis with or without nasal polyposis (CRSw/sNP). METHODS We planned a total of four annual blood samples to measure AEC in- and out-seasonal pollen exposure (i.e., one measurement every three months for one year). RESULTS We identified two distinct groups of patients (non-eosinophilic and eosinophilic). Patients in the eosinophilic group presented with four different patterns (episodic, transient, floating, and persistent). Most patients with episodic, transient, and floating patterns were affected by mild allergy and the increase in eosinophils was related to allergen exposure. In contrast, patients with the persistent pattern mostly presented with more severe allergy (i.e., severe BA and relapsing CRSwNP) and the eosinophilia was unrelated to allergen exposure. The subgroup of patients with severe BA, relapsing CRSwNP, and persistent eosinophilc pattern were treated with benralizumab, which induced a noteworthy improvement in both severe BA and CRSwNP. CONCLUSIONS Multiple AEC measurements in patients with seasonal allergy can better reflect patient's eosinophilic status and help define the relationship of AEC enhancement with allergen exposure.

Abstract
INTRODUCTION Add-on biological monoclonal antibodies such as benralizumab (anti-IL-5Ra) are recommended by international guidelines to reduce exacerbations in severe eosinophilic asthma (SEA). However, few studies have assessed the impact of these therapies on lung function-related outcomes. Our goal was to evaluate the effectiveness of benralizumab on lung function, including lung volumes and airway resistance, in SEA patients in Portugal. METHODS This was a real-world, observational, prospective, multicentric study including adult patients diagnosed with SEA (January-June 2023). Spirometry and plethysmography were performed at baseline (T0) and after six months of treatment (T6) with benralizumab to assess: total lung capacity (TLC), residual volume (RV), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), mean forced expiratory flow between 25% and 75% of FVC (mFEF-25/75), intrathoracic gas volume (ITGV), and respiratory airway resistance (Raw). Descriptive statistics (with categorical variables described as frequencies and continuous values as mean and standard deviation (SD)) and paired t-test and Cohen's d effect size were calculated (analyses performed in StataCorp v.15.1; StataCorp LLC, TX, USA). RESULTS Overall, 30 SEA patients were evaluated, mostly women (n=18, 60.0%), with atopy (n=22, 73.3%), a mean age of 58.4 years (SD 11.7), and assisted by pulmonology (n=19, 63.3%) or immunology-allergology (n=11, 36.7%) services. Mean eosinophilia at baseline was 1103.57 cells/mcL (SD 604.88; minimum-maximum 460-2400); after the use of benralizumab, the count dropped to zero. After six months of treatment, a significant increase (p<0.0001) in FVC (15.3%), FEV1 (22.6%), and mFEF-25/75 (17.7%) were observed from baseline (Cohen's d between 0.78 and 1.11). ITGV, RV, RV/TLC, and Raw significantly decreased (p<0.0001) during the study period (-17.3%, -29.7%, -8.9%, and -100.6%, respectively) (Cohen's d between -0.79 and -1.06). No differences in TLC were obtained (p=0.173). No differences between sexes were observed for any measure. Patients with more significant eosinophilia (>900 cells/mcL count; n=15) presented better responses in FEV1 (p=0.001) and mFEF-25/75 (p=0.007). CONCLUSIONS A notable eosinophil depletion with add-on benralizumab led to significant improvements in SEA patients' respiratory function (static lung volumes and airway resistance) in real-world settings after six months. The significant deflating effect of benralizumab on patients' hyperinflated lungs led to enhanced expiratory flow (increased FEV1 and mFEF-25/75) and air trapping (decreased RV/TLC), suggesting this antibody improves bronchial obstruction, lung hyperinflation, and airway resistance. Further studies in a larger population are required to confirm these findings.

Abstract
BACKGROUND AND OBJECTIVE This study compared the clinical outcomes of severe asthmatics treated with mepolizumab and benralizumab in a tertiary care severe asthma service setting. METHODS Patient data at baseline, six and 12 months were collected prospectively at two large tertiary hospital severe asthma clinics following treatment initiation. Two hundred and four patients received treatment with mepolizumab (117) or benralizumab (87). Baseline characteristics between groups were similar in regard to age, gender, body mass index, steroid dose and blood eosinophil count. However, the mepolizumab cohort had a higher Asthma Control Questionnaire Score (ACQ) at baseline (4.0 ± 1.1 vs. 3.6 ± 0.9, p = 0.018), accompanied by more frequent reliever medication usage and lower prebronchodilator FEV1 % (56.0 ± 20.1 vs. 63.8 ± 18.9, p = 0.008). RESULTS After 6 months treatment, both treatments induced significant improvements in (i) ACQ of 2.3 ± 0.1 (p < 0.001), (ii) oral steroid requiring exacerbations (incident rate ratio 0.26 (0.18-0.37), p < 0.001) and (iii) FEV1 . However, the improvement in FEV1 was 0.18 (0.05-0.30) litres greater with benralizumab than with mepolizumab (p = 0.002) even when adjusting statistically for baseline differences between groups. These differences were even more pronounced at 12 months post-treatment initiation, when the improvement in exacerbation frequency with benralizumab was 64% greater than with mepolizumab (p = 0.01). Whilst both treatments significantly reduced the blood eosinophil count at 6 and 12 months, this reduction was substantially greater with benralizumab than mepolizumab (-260 cells/μL [-400 to -110, p = 0.001]). CONCLUSION In this large group of severe eosinophilic asthmatics, mepolizumab and benralizumab both improved disease parameters. However, benralizumab treatment appeared significantly more effective than mepolizumab in reducing exacerbations, improving FEV1 and depleting blood eosinophils.

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
INTRODUCTION Dupilumab, a fully human anti-interleukin-4/interleukin-13 monoclonal antibody, has shown efficacy in many aspects of Type-2 severe asthma management. Currently, we lack real-life studies addressing the achievment of clinical remission in patients treated with this biologic. MATERIALS AND METHODS We performed a prospective study enrolling 18 patients with severe asthma treated with Dupilumab. We assessed main clinical, functional and biological severe asthma features at baseline (T0) and after a 1-year course of treatment (T12). Clinical remission was defined at T12 in patients without asthma exacerbations, no oral corticosteroid (OCS) use, ACT ≥ 20 and FEV1 improvement ≥ 100 ml from baseline. RESULTS Among total population, 38.9% of patients achieved clinical remission at T12. Anti IL-4/IL-13 treatment significantly reduced asthma exacerbations and OCS use in the overall cohort, with a more pronounced ACT improvement in the remission group. Patients achieving clinical remission went through a step down of the inhalation therapy, suspending long-acting anti-muscarinics administration at T12. CONCLUSIONS Treatment with anti-IL4/IL13 can induce clinical remission in patients with T2 severe asthma.

Abstract
BACKGROUND The prevalence of clinical asthma remission with biologics in severe asthma has not been well understood yet. We do not even know whether there might be characteristics that identify subjects prone to remission of the disease. MATERIALS AND METHODS Retrospectively, four groups of severe asthmatics already treated with Omalizumab, Mepolizumab, Benralizumab and Dupilumab (302, 55, 95 and 34 patients, respectively) for at least 12 months were considered. The number of individuals with clinical asthma remission was sought in each group. This was considered when patients, after a treatment of at least 1 year with one of the aforesaid biologics, showed the disappearance of asthma symptoms (ACT ≥ 20), zero exacerbations, suspension of oral corticosteroids and a FEV1% ≥ 80%. Baseline characteristics of patients with and without remission were also taken into account. RESULTS The prevalence of asthma remission after a mean of 37.8 ± 19.2, 13.5 ± 1.7, 15.4 ± 5.5 and 12 ± 0 months of Omalizumab, Mepolizumab, Benralizumab and Dupilumab treatments was 21.8%, 23.6%, 35.8% and 23.5%, respectively. For each biologic, different baseline characteristics, seem to be associated with failure to achieve clinical asthma remission. Older age, higher BMI, a later age of asthma onset, rhinitis/sinusitis/nasal polyposis, comorbidities and a greater asthma severity may be the characteristics of a suboptimal response to biologic treatments. CONCLUSION All biologics have the potential to induce disease remission in severe asthmatics. For each biologic, there may be several markers that can identify the patients who will not achieve asthma remission. It would be important to detect them (by carrying out targeted studies) as they would allow us to select the best biologic that may induce clinical asthma remission on a larger number of patients.

Abstract
Mepolizumab, a humanized anti-IL-5 monoclonal antibody used for severe asthma, results in a reduced rate of asthma exacerbation, improved lung function, reduced oral corticosteroid use, and improved quality of life. A 62-year-old man using high-dose inhaled corticosteroid visited our hospital because of poorly-controlled asthma. He had eosinophilia in peripheral blood and sputum, and high levels of fraction of exhaled nitric oxide. Therefore, he was treated with mepolizumab for severe asthma. Mepolizumab treatment resulted in significantly improved pulmonary function and reduced frequencies of asthma exacerbations. Because of his good asthma control, mepolizumab treatment was discontinued after 3 years. Since discontinuing mepolizumab, his asthma control has remained without exacerbation. Previous studies suggest that mepolizumab should be continued to sustain clinical benefits. However, cases of long-term controlled asthma have not been reported after mepolizumab withdrawal, and our case may be instructive.

Abstract
BACKGROUND The efficacy of benralizumab has been broadly demonstrated in severe eosinophilic asthma (SEA), but only few real-life studies evaluated its long-term effects. Here we present novel data from the ANANKE study in which a large cohort of SEA patients was treated for up to 96 weeks. METHODS ANANKE (NCT04272463) is an observational retrospective Italian study investigating the key characteristics of SEA patients (collected during the 12 months prior to benralizumab initiation) and the clinical outcomes during benralizumab treatment (annual exacerbation rate [AER], lung function, asthma control, OCS use, healthcare resource utilization). A post hoc analysis was also conducted in groups of patients based on history of previous biologic therapy (bio-experienced versus naïve patients). Analyses were descriptive only. RESULTS Before benralizumab initiation, evaluable SEA patients (N = 162, 61.1% females, mean age 56.0 ± 12.7) showed a median blood eosinophil count (BEC) of 600 cells/mm3 (IQR: 430-890). Patients experienced frequent exacerbations (annualized exacerbation rate [AER]: 4.10, severe AER: 0.98), with impaired lung function and poor asthma control (median ACT score: 14) despite 25.3% reported oral corticosteroid (OCS) use. Nasal polyposis was present in 53.1% patients; 47.5% patients were atopic. After 96 weeks since the start of benralizumab, nearly 90% patients were still on treatment; benralizumab dramatically decreased exacerbations (AER: - 94.9%; severe AER: - 96.9%), improved respiratory parameters (median increase in pre-bronchodilator forced expiratory volume [pre-BD FEV1]: + 400 mL) and asthma control (median ACT score: 23) while eliminating OCS in 60% patients. Importantly, benralizumab effects were either maintained or progressively improved over time, accompanied by a nearly complete depletion of BEC. Benralizumab reduced AER both in naïve (any AER: - 95.9%; severe AER: - 97.5%) and bio-experienced patients (any AER: - 92.4%; severe AER: - 94.0%). CONCLUSIONS Profound and sustained improvements in all asthma outcomes were observed with benralizumab. The correct identification of patients' eosinophilic-driven asthma phenotype was essential to ensure the achievement of such remarkable results.

Abstract
Asthma and nasal polyposis often coexist and are frequently intertwined by tight pathogenic links, mainly consisting of the cellular and molecular pathways underpinning type 2 airway inflammation. The latter is characterized by a structural and functional impairment of the epithelial barrier, associated with the eosinophilic infiltration of both the lower and upper airways, which can be driven by either allergic or non-allergic mechanisms. Type 2 inflammatory changes are predominantly due to the biological actions exerted by interleukins 4 (IL-4), 13 (IL-13), and 5 (IL-5), produced by T helper 2 (Th2) lymphocytes and group 2 innate lymphoid cells (ILC2). In addition to the above cytokines, other proinflammatory mediators involved in the pathobiology of asthma and nasal polyposis include prostaglandin D2 and cysteinyl leukotrienes. Within this context of 'united airway diseases', nasal polyposis encompasses several nosological entities such as chronic rhinosinusitis with nasal polyps (CRSwNP) and aspirin-exacerbated respiratory disease (AERD). Because of the common pathogenic origins of asthma and nasal polyposis, it is not surprising that the more severe forms of both these disorders can be successfully treated by the same biologic drugs, targeting many molecular components (IgE, IL-5 and its receptor, IL-4/IL-13 receptors) of the type 2 inflammatory trait.

Subsets of Eosinophils in Asthma, a Challenge for Precise Treatment. Int J Mol Sci 2023; 24:ijms24065716. [PMID: 36982789 PMCID: PMC10052006 DOI: 10.3390/ijms24065716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 03/10/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023] Open
Abstract
The existence of eosinophils was documented histopathologically in the first half of the 19th century. However, the term “eosinophils” was first used by Paul Ehrlich in 1878. Since their discovery and description, their existence has been associated with asthma, allergies, and antihelminthic immunity. Eosinophils may also be responsible for various possible tissue pathologies in many eosinophil-associated diseases. Since the beginning of the 21st century, the understanding of the nature of this cell population has undergone a fundamental reassessment, and in 2010, J. J. Lee proposed the concept of “LIAR” (Local Immunity And/or Remodeling/Repair), underlining the extensive immunoregulatory functions of eosinophils in the context of health and disease. It soon became apparent that mature eosinophils (in line with previous morphological studies) are not structurally, functionally, or immunologically homogeneous cell populations. On the contrary, these cells form subtypes characterized by their further development, immunophenotype, sensitivity to growth factors, localization, role and fate in tissues, and contribution to the pathogenesis of various diseases, including asthma. The eosinophil subsets were recently characterized as resident (rEos) and inflammatory (iEos) eosinophils. During the last 20 years, the biological therapy of eosinophil diseases, including asthma, has been significantly revolutionized. Treatment management has been improved through the enhancement of treatment effectiveness and a decrease in the adverse events associated with the formerly ultimately used systemic corticosteroids. However, as we observed from real-life data, the global treatment efficacy is still far from optimal. A fundamental condition, “sine qua non”, for correct treatment management is a thorough evaluation of the inflammatory phenotype of the disease. We believe that a better understanding of eosinophils would lead to more precise diagnostics and classification of asthma subtypes, which could further improve treatment outcomes. The currently validated asthma biomarkers (eosinophil count, production of NO in exhaled breath, and IgE synthesis) are insufficient to unveil super-responders among all severe asthma patients and thus give only a blurred picture of the adepts for treatment. We propose an emerging approach consisting of a more precise characterization of pathogenic eosinophils in terms of the definition of their functional status or subset affiliation by flow cytometry. We believe that the effort to find new eosinophil-associated biomarkers and their rational use in treatment algorithms may ameliorate the response rate to biological therapy in patients with severe asthma.

Remission outcomes in severe eosinophilic asthma with mepolizumab therapy: Analysis of the REDES study. Front Immunol 2023; 14:1150162. [PMID: 37122713 PMCID: PMC10131245 DOI: 10.3389/fimmu.2023.1150162] [Citation(s) in RCA: 23] [Impact Index Per Article: 23.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 03/16/2023] [Indexed: 05/02/2023] Open
Abstract
Introduction Clinical remission as a multicomponent treatment goal in severe asthma is being explored in clinical practice. This post hoc analysis used data from the REDES study to assess the proportion of patients with severe eosinophilic asthma achieving our multicomponent definitions of clinical remission after 1 year of mepolizumab treatment. Methods The real-world, retrospective observational REDES study enrolled patients with severe eosinophilic asthma who were newly prescribed mepolizumab and with ≥12 months of medical records pre-enrolment. Multicomponent clinical remission was defined as: oral corticosteroid (OCS)-free; exacerbation-free; asthma control test (ACT) score ≥20; and with or without post-bronchodilator forced expiratory volume in 1 second ≥80%. Baseline characteristics were also assessed in those who did/did not achieve clinical remission. Results 37% and 30% of patients with severe eosinophilic asthma met our proposed three- and four-component on-treatment clinical remission definitions; an increase from 2% and 3% at baseline. Most frequently achieved individual components of clinical remission were: OCS-free; ACT score ≥20. For patients fulfilling the multicomponent clinical remission definitions, at baseline we observed higher blood eosinophil counts, better ACT scores and lung function, lower maintenance OCS use, and a slightly lower rate of prior exacerbations versus those who did not. Discussion Clinical remission is a realistic target in clinical practice for a subset of patients with severe eosinophilic asthma receiving mepolizumab. Further studies are required to elucidate whether features linked to the underlying endotype can help predict treatment outcomes, increase rates of clinical remission, and potentially modify disease progression.
