Abstract
The past 2 decades have seen a revolution in our approach to therapeutic immunosuppression. We have moved from relying on broadly active traditional medications, such as prednisolone or methotrexate, toward more specific agents that often target a single receptor, cytokine, or cell type, using monoclonal antibodies, fusion proteins, or targeted small molecules. This change has transformed the treatment of many conditions, including rheumatoid arthritis, cancers, asthma, and inflammatory bowel disease, but along with the benefits have come risks. Contrary to the hope that these more specific agents would have minimal and predictable infectious sequelae, infectious complications have emerged as a major stumbling block for many of these agents. Furthermore, the growing number and complexity of available biologic agents makes it difficult for clinicians to maintain current knowledge, and most review articles focus on a particular target disease or class of agent. In this article, we review the current state of knowledge about infectious complications of biologic and small molecule immunomodulatory agents, aiming to create a single resource relevant to a broad range of clinicians and researchers. For each of 19 classes of agent, we discuss the mechanism of action, the risk and types of infectious complications, and recommendations for prevention of infection.

Abstract
PURPOSE OF REVIEW There has been an explosion of monoclonal antibodies in the treatment of severe uncontrolled adult asthma. Studies have now been published in severe pediatric asthma. There are numerous questions that need to be answered in determining whether these modalities are appropriate and safe in children. RECENT FINDINGS This is a narrative review examining the latest pediatric literature on monoclonal antibodies, both approved and in the pipeline, for uncontrolled asthma. Presently, all of the biologics are positioned to treat patients with underlying type 2 high disease. Two monoclonal antibodies are approved for children 6 years of age and older, omalizumab and mepolizumab, with more likely approved in the near future. The effect of these agents in controlling severe pediatric asthma is promising. Data is limited to long-term efficacy and safety, and whether any agent has an effect on the natural history of asthma.

Abstract
BACKGROUND Asthma is a common and potentially serious condition affecting 300 million people worldwide. For many years, we have relied on a one-size-fits-all approach to its management, using corticosteroids and bronchodilators for all symptomatic patients. However, with more recent advances, it has become clear that asthma is a heterogeneous condition with multiple different underlying pathways. Understanding the different subtypes will be a key to giving us the ability to intervene in a targeted way to personalize care for patients with asthma. SOURCES OF DATA Key published literature, guidelines and trials from clinicaltrials.gov. AREAS OF AGREEMENT The most widely studied of these subtypes is T2 high eosinophilic asthma, for which there are an increasing number of biologic therapies available. T2 high asthma is associated with the cytokines interleukin (IL)-4, IL-5 and IL-13, for each of which biologics have been developed. AREAS OF CONTROVERSY It is currently unclear which of the available biologics provides superior efficacy. It is also unclear how to select which biologic for which patient. GROWING POINTS Head-to-head trials of the available T2 biologics will be important to determine superiority, and a suggested order for trialling biologics. Going further than this, we would like to see further analyses of available biologics to allow us to predict responders from non-responders in advance of administering therapy. AREAS TIMELY FOR DEVELOPING RESEARCH Non-eosinophilic T2 low asthma is an area that is under-researched and for which there are few treatments available. It is likely that there are different subtypes in this category of asthma and unravelling what these are will be crucial to developing effective treatments.

Abstract
Targeting interleukins that drive innate inflammation has expanded treatments of autoinflammatory and autoimmune disorders. Interleukin (IL)-1 inhibition has proven useful for monogenic autoinflammatory syndromes, and IL-6 inhibition for autoimmune arthritides. Biological therapies impeding these pathways impair detection and containment of pathogens, particularly invasive bacteria, reflecting the importance of IL-1 and IL-6 in communicating danger throughout the immune system. Biologics targeting T helper type 2 inflammation are used to treat specific allergic, atopic, and eosinophilic diseases. They may impair protections against local herpesvirus reactivations while augmenting antiviral responses to respiratory viruses. Their risks with helminth exposures have yet to be defined.

Abstract
Asthma is now recognised as a heterogenous inflammatory disease of the lung based on cellular infiltrates and transcriptional profiles of blood and airway cells. Four distinct subgroups have been defined, eosinophilic (T2), neutrophilic (T1), mixed eosinophilic/neutrophilic and paucigranulocytic. Patients can also be stratified at a molecular level into T2-high, T2-low and/or T1 based on their gene signatures. Current treatments for asthma have been centred on administration of steroids and/or bronchodilators for the relief of bronchoconstriction and inflammation. These treatments are not always effective and often have limited efficacy during exacerbations. Eosinophil expansion and homing to tissues, bronchoconstriction, IgE production and mucus hypersecretion (hallmark features of asthma) are regulated by the type 2 cytokines IL-4, IL-5 and IL-13, the latter of which can induce the expression of the eosinophil chemotactic factors CCL11 and CCL24. A number of new generation biologics (monoclonal antibodies) targeting pathways regulated by the T2 cytokines IL-5 and IL-4/13 (IL-4 receptor alpha) have yielded effective therapies for eosinophil induced exacerbations of severe asthma. Despite these advances, difficulties still remain in treating all exacerbations, and this may reflect the contribution of other inflammatory cells such as neutrophils to pathogenesis. This review describes the effectiveness of targeting T2 pathways, emerging approaches and identifies the potential next steps for therapeutic intervention.

Abstract
Introduction: An estimated 5-10% of people with asthma have disease which remains uncontrolled despite maximal treatment with inhaled corticosteroids and long-acting beta-agonists. Benralizumab is currently licensed for use in patients with severe asthma who have an eosinophilic phenotype. Benralizumab depletes eosinophils by binding to the anti-IL5 receptor on the surface of eosinophils, mitigating the effect of IL-5 on eosinophil proliferation and survival, and induces natural killer cell-mediated eosinophil apoptosis.Areas covered: The authors review the mechanism of action and pharmacokinetic profile of Benralizumab and summarize the scientific data supporting its clinical efficacy and safety in severe asthma. Further, the authors highlight future studies of Benralizumab in asthma and other diseases.Expert opinion: Benralizumab lowers exacerbation rates, symptom burden, and oral glucocorticoid use, and improves lung function, in patients with severe eosinophilic asthma. Benralizumab is well tolerated and is an attractive choice for patients and physicians due to its eosinophil-depleting mechanism of action and less frequent dosing schedule. More data is needed to guide the selection of biologic therapy in severe asthma patients.

Abstract
Bronchial thermoplasty is an advanced therapy for severe asthma. It is a bronchoscopic procedure in which radiofrequency energy is applied to the airway wall, resulting in decreased airway smooth muscle burden. Human trials have shown that bronchial thermoplasty may reduce asthma exacerbations and improve quality of life in patients with severe uncontrolled asthma. It has been demonstrated to be a safe procedure, with most adverse events being early and mild. More studies are required to understand the precise effects of bronchial thermoplasty on the asthmatic airway and optimal parameters to appropriately select patients for this novel procedure.

Abstract
Interleukin-5 (IL-5) exerts a central pathogenic role in differentiation, recruitment, survival, and degranulation of eosinophils. Indeed, during the last years, significant advances have been made in our understanding of the cellular and molecular mechanisms underlying the powerful actions of IL-5 finalized to the induction, maintenance, and amplification of eosinophilic inflammation. Therefore, IL-5 is a suitable target for add-on biological therapies based on either IL-5 inhibition (mepolizumab, reslizumab) or blockade of its receptor (benralizumab). These modern treatments can result in being definitely beneficial for patients with severe type 2 (T2)-high eosinophilic asthma, refractory to conventional anti-inflammatory drugs such as inhaled and even systemic corticosteroids.

Abstract
Background Healthcare decisions made on the basis of insufficient evidence may potentially have ineffective or even harmful consequences. The proportion of older ages (over 65 years) in randomized controlled trials (RCTs) for severe asthma is not enough to establish whether anti-IL-5/IL-5R therapies are equally effective in the elderly as in younger subjects. Methods In order to assess the relationship between age and the efficacy of anti-IL-5 monoclonal antibodies (mABs) with respect to the risk of exacerbations and changes in FEV1, a meta-regression analysis via random-effect method was carried out by plotting the effect estimates (outcome variables) resulting from the pairwise meta-analysis with the age of asthmatic subjects (explanatory variable). A comprehensive literature search was performed for pivotal RCTs on the effects of anti-IL-5/IL-5R in severe asthma, with the following keywords: "asthma and mepolizumab", "asthma and reslizumab" and "asthma and benralizumab". The study was restricted to "clinical trials", "age over 65" and "humans". Data were checked for age, exacerbation rates, changes from baseline in FEV1, and blood eosinophil (Eos) count. Secondary outcomes included inhaled and oral medication use, clinical scores and quality of life. Results A total of 10 studies were analysed. Age did not modulate the efficacy of anti-IL-5/IL-5R treatment against the risk of exacerbation neither in the overall population (coefficient -0.007, P = 0.89), nor in patients with high blood Eos count (coefficient 0.075, P = 0.30). The blood Eos level drove the efficacy of anti-IL-5/IL-5R mABs against the risk of exacerbation regardless of age (coefficient -0.27, P < 0.001). Age did not significantly affect the efficacy of anti-IL-5/IL-5R mABs with respect to the change in FEV1 (coefficient -7.15, P = 0.190); however, in high Eos subjects this improvement tended to be less evident in the more advanced age ranges (coefficient -15.18, P = 0.087). In addition, anti-IL-5/IL-5R mABs reduced ACQ score (P < 0.001 vs. placebo), SGRQ score (P < 0.001 vs. placebo), Total Asthma Symptom Score (P < 0.05 vs. placebo), and the use of oral glucocorticoids (P < 0.001 vs. placebo). Conclusions Age does not negatively affect the efficacy of anti-IL-5/IL-5R mABs. These findings support the use of anti-IL-5/IL-5R mABs in asthmatics of different age ranges.

Abstract
Severe obstructive lung disease, which encompasses asthma, chronic obstructive pulmonary disease (COPD) or features of both, remains a considerable global health problem and burden on healthcare resources. However, the clinical definitions of severe asthma and COPD do not reflect the heterogeneity within these diagnoses or the potential for overlap between them, which may lead to inappropriate treatment decisions. Furthermore, most studies exclude patients with diagnoses of both asthma and COPD. Clinical definitions can influence clinical trial design and are both influenced by, and influence, regulatory indications and treatment recommendations. Therefore, to ensure its relevance in the era of targeted biologic therapies, the definition of severe obstructive lung disease must be updated so that it includes all patients who could benefit from novel treatments and for whom associated costs are justified. Here, we review evolving clinical definitions of severe obstructive lung disease and evaluate how these have influenced trial design by summarising eligibility criteria and primary outcomes of phase III randomised controlled trials of biologic therapies. Based on our findings, we discuss the advantages of a phenotype- and endotype-based approach to select appropriate populations for future trials that may influence regulatory approvals and clinical practice, allowing targeted biologic therapies to benefit a greater proportion and range of patients. This calls for co-ordinated efforts between investigators, pharmaceutical developers and regulators to ensure biologic therapies reach their full potential in the management of severe obstructive lung disease.

Abstract
Purpose Accessorized prefilled syringes (APFS) have demonstrated functionality and reliability for subcutaneous (SC) delivery, including self-administration, of benralizumab 30 mg in the clinic or at home. The multicenter, open-label GRECO study (NCT02918071) assessed functionality and reliability of a single-use autoinjector (AI) for at-home benralizumab administration by patients or their caregivers. Patients and methods Adults with severe asthma received benralizumab SC injections at the study site at Weeks 0, 4, and 8. The first dose was administered by health care providers. Patients/caregivers had the option of administering the second dose and were required to administer the third dose under supervision. At Weeks 12 and 16, patients/caregivers administered benralizumab via AI at home. After each administration, patients/caregivers completed questionnaires concerning administration and device functioning. All AI devices used were returned for evaluation. Results A total of 595 AIs were used for 121 patients (mean age 48.5 years; 64% female) in the clinic and at home. Of 116 participants, 113 (97.4%; 95% confidence interval [CI]: 92.63–99.46) and 112 (96.6%; 95% CI: 91.41–99.05) successfully administered benralizumab at home at Weeks 12 and 16, respectively; 108 (93.1%; 95% CI: 86.86–96.98) were successful on both occasions. Throughout the study, 10 (1.7%) AI administrations were unsuccessful: 8 (1.3%) because of user error, 1 (0.2%) with undetermined cause, and 1 (0.2%) because of a manufacturing defect. Benralizumab efficacy (assessed by Asthma Control Questionnaire 6 score) and pharmacokinetics for patients using the AI were comparable to published results for patients receiving benralizumab via syringe in a clinical setting. No new or unexpected safety findings were observed. Conclusion AIs were functional, reliable, and performed well in the clinic and at home. Nearly all patients and caregivers successfully administered SC benralizumab via AI. Benralizumab availability in AI and APFS could provide patients with choices for self-administration.

Abstract
Cytokines play a key role in orchestrating and perpetuating the chronic airway inflammation in asthma and chronic obstructive pulmonary disease (COPD), making them attractive targets for treating these disorders. Asthma and some cases of COPD are mainly driven by type 2 immune responses, which comprise increased airway eosinophils, T helper 2 (TH2) cells and group 2 innate lymphoid cells (ILC2s) and the secretion of IL-4, IL-5 and IL-13. Clinical trials of antibodies that block these interleukins have shown reduced acute exacerbations and oral corticosteroid use and improvements in lung function and symptoms in selected patients. More recent approaches that block upstream cytokines, such as thymic stromal lymphopoietin (TSLP), show promise in improving patient outcome. Importantly, the clinical trials in cytokine blockade have highlighted the crucial importance of patient selection for the successful use of these expensive therapies and the need for biomarkers to better predict drug responses.

Abstract
Since novel treatments to target eosinophilic inflammation in Type 2 asthma are emerging, we aimed to evaluate and meta-analyze the efficacy of monoclonal antibodies to reduce exacerbation rate. PubMed and Web of Science were searched for phase II and phase III randomized clinical trials with monoclonal antibodies targeting key mediators of type 2-associated asthma. Thirty trials were selected involving biologics that target the IL-5 pathway, IL-13, the common IL-4 and IL-13 receptor, IL-9, IL-2 and TSLP. As no head-to-head trials were retrieved from literature, we performed an arm-based network meta-analysis to compare effects on exacerbation rate between the different treatments. Mepolizumab, reslizumab and benralizumab significantly reduced the risk of exacerbations compared to placebo (by 47–52%, 50–60%, and 28–51% respectively). Reslizumab and benralizumab also improved lung function. Dupilumab and tezepelumab improved lung function in frequent exacerbators. Lebrikizumab had no significant effect on the number of exacerbations, symptom control or health-related quality of life. Tralokinumab improved lung function compared to placebo. Network meta-analysis of all treatment and placebo arms, showed no superiority of one biologic over the others. Large reductions in exacerbation rates were observed compared to placebo, though only benralizumab was sufficiently powered (n = 2051) to demonstrate significantly decreased exacerbation rates in the subgroup analysis of IL-5 acting agents compared to placebo. Monoclonal antibodies such as mepolizumab, reslizumab and benralizumab have proven their benefit to reduce exacerbation rates in severe persistent eosinophilic asthma in the published trials. However, no statistically significant superiority was observed of one biologic over the other in the network meta-analysis. More studies with direct head to head comparisons and better defined endotypes are required.

Abstract
Severe asthma in children remains a significant issue. It places a heavy burden on affected individuals and society as a whole in terms of high morbidity, mortality, consumption of healthcare resources, and side effects from high-dose corticosteroid therapy. New, targeted biologic therapies for asthma have emerged as effective add-on options, complementing our expanding understanding of asthma phenotypes/endotypes and the underlying immunopathology of the disease spectrum. They include omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab. Omalizumab represents the first available therapeutic option for allergic asthma in patients as young as 6 years of age. Its efficacy and safety have been established by several randomized controlled trials specifically conducted in pediatric patients, leading to its final registration > 10 years ago. Three new interleukin (IL)-5 targeted agents, mepolizumab, reslizumab, and benralizumab, have been approved for the treatment of severe eosinophilic asthma starting from 6 years of age, and varying by country. More recently, dupilumab, a targeted agent against the IL-4 receptor α-chain, was approved for patients ≥12 years of age in the United States after pivotal trials were completed. The late-stage clinical testing of these targeted agents has mostly involved patients aged 12 years and up, and the application of those data to younger children can be inappropriate and carry risk. The efficacy and safety of these newer biologics in children should be supported by adequate research within this targeted age group. In this review, we will present the most recent evidence on these five biological therapies for severe asthma and will discuss dosage and administration, their efficacy, safety, and future prospects, with a focus on the pediatric age group, defined as age < 18 years.

Real-life rapidity of benralizumab effects in patients with severe allergic eosinophilic asthma: Assessment of blood eosinophils, symptom control, lung function and oral corticosteroid intake after the first drug dose. Pulm Pharmacol Ther 2019; 58:101830.

Abstract
Benralizumab is a humanized monoclonal antibody which binds to the α subunit of the interleukin-5 (IL-5) receptor and to the FcγRIIIa receptor expressed by natural killer cells, thus suppressing the pro-eosinophil actions of IL-5 and triggering eosinophil apoptosis via the very effective mechanism of antibody-dependent cell-mediated cytotoxicity (ADCC). Because of its recent approval and introduction in clinical practice for the add-on biological therapy of severe eosinophilic asthma, real-life investigations are still lacking. In this regard, our present real-life study refers to 13 patients with severe allergic eosinophilic asthma, currently under treatment with benralizumab at the Respiratory Unit of "Magna Græcia" University Hospital located in Catanzaro, Italy. Already 4 weeks after the first subcutaneous injection of benralizumab at the dosage of 30 mg, blood eosinophil count rapidly dropped down from 814.7 ± 292.3 cells/μL to 51.3 ± 97.5 cells/μL (p < 0.0001). This relevant hematologic change was associated with quick and significant increases in asthma control test (ACT) score (from 15.31 ± 2.78 to 21.15 ± 3.58; p < 0.0001), pre-bronchodilator forced expiratory volume in 1 s (FEV1) (from 1441 ± 757.9 mL to 1887 ± 837.3 mL; p < 0.001), and morning peak expiratory flow (PEF) (from 4.21 ± 2.20 to 5.33 ± 1.99 L/sec; p < 0.01). Furthermore, the marked improvement in global health status experienced by our patients allowed them to progressively lower and then completely interrupt, within 4 weeks, their daily intake of oral corticosteroids (OCS), which thereby fell from 15.58 ± 8.30 to 0 mg (p < 0.0001) of prednisone. Therefore, such preliminary results suggest that in patients with severe allergic eosinophilic asthma benralizumab can exert, within a real-life context, a very rapid and effective therapeutic action, already detectable 4 weeks after the first drug administration.

Abstract
Objective: Asthma is a common heterogeneous disease characterized by airway inflammation and bronchoconstriction. Current treatment guidelines provide recommendations for categorizing disease severity, asthma control and management. This paper reviews asthma assessment in primary care and describes the pathophysiology, clinical characteristics and new targeted treatments available for patients with severe eosinophilic asthma. Methods: A non-systematic PubMed literature search was conducted and articles, primarily from the last 5 years, were selected based on relevance to primary care practice, asthma pathophysiology and biologic therapies. Results: Despite optimal therapy including high-dose inhaled corticosteroids (ICS), long-acting β2-agonists and tiotropium, ∼4-10% of all patients with severe asthma continue to have poor asthma control. These patients have impaired quality of life, frequent exacerbations and are exposed to the side effects of repeated courses of oral steroids. Approximately 50% of patients with severe uncontrolled asthma have eosinophilic asthma, with increased airway expression of type 2 cytokines IL-4, IL-5 and IL-13. Eosinophilic asthma is identified in primary care by having eosinophils ≥150-300 cells/μL on a complete blood count with differential. Conclusions: A new class of agents is available for patients with moderate to severe eosinophilic asthma. Four biologic therapies - mepolizumab, reslizumab, benralizumab and dupilumab - that interfere with the regulation and activity of eosinophils have been approved by the FDA for patients with moderate to severe asthma with an eosinophilic phenotype. Primary care physicians should be familiar with these medications to explain part of the rationale for referral to specialist care and manage patient expectations for treatment.

Abstract
In the last decades, the increasing evidence concerning inflammation mechanisms underlying severe eosinophilic asthma has highlighted new potential therapeutic targets and has paved the way to new selective biologic drugs. Understanding the mechanism of action and the clinical outcomes of a particular drug along with the clinical and biological characteristics of the patient population for which that drug was intended may ensure appropriate selection of patients that will respond to that drug. Under this perspective, the present review will focus on the mechanisms of action and clinical evidence of benralizumab as a treatment option for severe eosinophilic asthma, in order to provide a concise overview and a reference for clinical practice. Benralizumab is a fully humanized afucosylated IgG1κ mAb that binds to an epitope on IL-5 Rα, and inhibits IL-5 signaling. Benralizumab also sustains antibody-directed cell-mediated cytotoxicity (ADCC) of eosinophils and basophils and consequently depletes IL-5Rα-expressing cells. As a result, it is responsible for a substantial depletion of blood, tissue, and bone marrow eosinophilia. This unique mechanism of action may account for a more complete and rapid action profile. Randomized clinical trials have demonstrated that benralizumab provides an optimal safety profile, and is able to significantly reduce asthma exacerbations, oral steroid intake, and to improve lung function. Some clinical predictors of enhanced clinical response to benralizumab have also been identified, including: a level of blood eosinophils ≥300 μL−1, oral steroids use, the presence of nasal polyposis, FVC <65% of predicted, and a history of three or more exacerbations per year at baseline. These results can be helpful in identifying the best responder patients to benralizumab. As a step forward, the definition of the responder profile for each of the available biological treatment options will potentially support even more the pathway to precision medicine and the critical matching of the right drug with the right patient.

Abstract
OBJECTIVE To summarize the current literature for Food and Drug Administration (FDA)-approved monoclonal antibodies used as add-on maintenance therapy in uncontrolled eosinophilic asthma. DATA SOURCES PubMed was searched on December 17, 2018 using keywords: asthma, eosinophilic asthma, omalizumab, reslizumab, mepolizumab, benralizumab, and dupilumab. STUDY SELECTION Studies evaluating safety and efficacy of monoclonal antibodies for treatment of severe or eosinophilic asthma were included. RESULTS Twenty-one randomized, double-blind, placebo-controlled trials evaluating the current FDA-approved monoclonal antibodies (omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab) for the treatment of uncontrolled eosinophilic asthma were included. The studies demonstrated clinically significant reductions in asthma exacerbations, symptoms, emergency room visits, eosinophil counts, and improvements in pulmonary function and asthma-related quality of life. CONCLUSION Five monoclonal antibodies are available for uncontrolled eosinophilic asthma. Choice depends on patient factors. Future studies should focus on cost-effectiveness of treatment, drug-drug comparisons, and long-term efficacy and safety.

Abstract
BACKGROUND Benralizumab, a humanized, anti-interleukin-5 (anti-IL-5) receptor α monoclonal antibody that directly and rapidly depletes eosinophils, has shown significant efficacy in reducing asthma exacerbations and improving lung function in moderate to severe eosinophilic asthma patients. However, there is some controversy regarding the adverse events (AEs) of benralizumab and a comprehensive analysis of these AEs has not been performed. This study aimed to assess the incidence of these AEs in published randomized controlled trials (RCTs). METHODS We searched for RCTs in the Embase, PubMed and Cochrane databases that compared benralizumab with placebo in moderate to severe eosinophilic asthma patients. The outcome was the incidence of AEs during the observation period. RESULTS Eight RCTs were analyzed in this study. Patients treated with benralizumab had a lower risk of overall AEs (risk ratio (RR) 0.94; 95% confidence interval (CI) 0.90-0.98), serious adverse events (SAEs) (RR 0.82; 95% CI 0.68-0.98), asthma exacerbation (RR 0.72, 95% CI 0.61-0.85), bronchitis (RR 0.76, 95% CI 0.59-0.96) and sinusitis (RR 0.64, 95% CI 0.48-0.85), but had a higher risk of headache (RR 1.42, 95% CI 1.07-1.87) and pyrexia (RR 2.26, 95% CI 1.32-3.87) than patients treated with placebo. No increased incidence of death, hypersensitivity, injection-site reactions, nasopharyngitis, rhinitis, upper respiratory tract infection, influenza, cough, nausea, back pain or arthralgia was observed with benralizumab compared with placebo. CONCLUSIONS Benralizumab reduced the risk of SAEs, asthma exacerbation, bronchitis and sinusitis, and aggravated the risk of headache and pyrexia. Other AEs were comparable between the benralizumab group and placebo group. Therefore, benralizumab is a relatively safe drug, but vigilance regarding AEs is imperative during long-term treatment.

Abstract
Kyowa Hakko Kirin, AstraZeneca and subsidiaries are developing benralizumab (Fasenra™)-a humanised anti-interleukin-5 receptor alpha chain (IL-5Rα) monoclonal antibody-as a treatment of severe eosinophilic asthma and chronic obstructive pulmonary disease (COPD). Eosinophilia is a characteristic of certain asthma and COPD phenotypes and depletion of eosinophils has demonstrated therapeutic benefit. Benralizumab was recently approved by the US FDA as add-on maintenance therapy for patients with severe asthma who have an eosinophilic phenotype. This article summarizes the milestones in the development of benralizumab leading to this first approval for the treatment of severe eosinophilic asthma.

Abstract
BACKGROUND Hypereosinophilic syndrome is a group of diseases defined by marked eosinophilia in blood or tissue and eosinophil-related clinical manifestations. Benralizumab is a monoclonal antibody against interleukin-5 receptor α, which is expressed on human eosinophils. METHODS In this randomized, double-blind, placebo-controlled, phase 2 trial, we administered a series of three monthly subcutaneous injections of either benralizumab (at a dose of 30 mg) or placebo in 20 symptomatic patients who had PDGFRA-negative hypereosinophilic syndrome and an absolute eosinophil count of at least 1000 cells per cubic millimeter; all the patients were receiving stable therapy (drugs or dietary changes) for this disease. This regimen was followed by an open-label phase, during which the patient's background therapy could be tapered as tolerated, and an extension phase. The primary end point of the randomized phase was a reduction of at least 50% in the absolute eosinophil count at week 12. RESULTS During the randomized phase, the primary end point occurred in more patients in the benralizumab group than in the placebo group (9 of 10 patients [90%] vs. 3 of 10 patients [30%], P = 0.02). During the open-label phase, clinical and hematologic responses were observed in 17 of 19 patients (89%) and were sustained for 48 weeks in 14 of 19 patients (74%); in the latter group, in 9 of 14 patients (64%), background therapies could be tapered. Bone marrow and tissue eosinophilia were also suppressed with benralizumab therapy. The most common drug-related adverse events, headache and an elevated lactate dehydrogenase level, occurred in 32% of the patients after the first dose of benralizumab and resolved within 48 hours in all patients. Other adverse events occurred with similar frequency in the two groups. Of the many potential predictors of response that were examined, only clinical disease subtype appeared to be associated with the initial response or relapse. CONCLUSIONS In this small phase 2 trial, patients with PDGFRA-negative hypereosinophilic syndrome who received benralizumab for 12 weeks had lower absolute eosinophil counts than those who received placebo. During the open-label phase, clinical and hematologic responses were sustained for 48 weeks in 74% of the patients. Adverse events did not limit treatment.

Abstract
While the origin of the phrase "birds of a feather flock together" is unclear, it has been in use for centuries and is typically employed to describe the phenomenon that people with similar tastes or interests tend to seek each other out and congregate together. In this review, we have co-opted this phrase to compare innate immune cells of related origin, the eosinophil and mast cell, because they very often accumulate together in tissue sites under both homeostatic and inflammatory conditions. To highlight overlapping yet distinct features, their hematopoietic development, cell surface phenotype, mediator release profiles and roles in diseases have been compared and contrasted. What emerges is a sense that these two cell types often interact with each other and their tissue environment to provide synergistic contributions to a variety of normal and pathologic immune responses.

Abstract
There are now multiple monoclonal antibodies targeting different inflammatory pathways of severe asthma. Benralizumab is a recently approved monoclonal antibody indicated for the treatment of severe eosinophilic asthma by targeting a subunit of the IL-5 receptor. Treatment with benralizumab results in significant reductions of blood and tissue eosinophils. Early studies report that this therapy has an adequate safety profile, and this was confirmed in later trials. Phase III studies have shown that benralizumab is effective in reducing the rate of exacerbations and improving asthma symptoms and quality of life in patients with severe eosinophilic asthma. Additionally, treatment with benralizumab has resulted in important reductions in the use of chronic oral corticosteroids. In this review, we evaluate the evidence up to date on the efficacy of benralizumab in severe eosinophilic asthma and explore the implications of this therapy in the ever-growing landscape of therapies for severe asthma.

Abstract
INTRODUCTION Severe or refractory asthma is seen in approximately 5% of asthmatic subjects who have unsatisfactory symptom control despite adherence to high-dose inhaled glucocorticoid therapies resulting in significant morbidity, reduced quality of life and health-care cost implications. Asthma exhibits marked heterogeneity both clinically and at the molecular phenotypic level requiring specifically targeted treatments to block the key pathways of the disease. Monoclonal antibody-based biologics targeted at inhibition of the type 2 cytokines IL-4, IL-5, and IL-13 have considerable potential as effective treatments for severe asthma. Areas covered: This review is based on recent English-language original articles in PubMed or Medline that reported significant clinical findings on the current status, therapeutic potential, and safety of biologics targeted at IL-4, IL-5, and IL-13 in the treatment of asthma together with the potential utility of simple reproducible non-invasive biomarkers to guide the effective use of biologic-based therapy that do not require direct sampling of the airways Expert commentary: The further development of reproducible and straightforward discriminatory non-invasive biomarkers may aid identification of those patients most likely to benefit from treatment with these interventions.

Abstract
INTRODUCTION Anti-interleukin-5 therapy has been proposed as a novel and promising treatment option in asthma treatment. However, the optimum monoclonal antibodies for asthma treatment remain uncertain. METHODS We searched the PubMed, EMBASE and Cochrane databases from their inceptions to June 2018 for randomized controlled trials that reported pulmonary function, adverse events, Asthma Quality of Life Questionnaire (AQLQ) scores, and asthmatic exacerbations resulting from anti-interleukin-5 therapy in asthma patients. Extracted data were analyzed by pairwise and network meta-analysis. RESULTS Twenty-one randomized studies were identified for this analysis. By pairwise meta-analysis using a placebo as the reference, patients treated with monoclonal antibodies were associated with significantly improved forced expiratory volume (FEV1) values (standard mean difference [SMD], 0.18; 95% confidence interval [CI], 0.12-0.23; P < 0.001), lower rates of adverse events (risk ratio [RR], 0.93; 95% CI, 0.90-0.97; P < 0.001) and significant improvements in the AQLQ scores (SMD, 0.20; 95% CI, 0.13-0.26; P < 0.001). There were no significant differences in exacerbations risks (RR, 0.68; 95% CI, 0.11-4.14; P = 0.097). According to network meta-analysis, adverse events-related benefits were seen only with reslizumab, while AQLQ scores benefits, and pulmonary function benefits were still seen with all three monoclonal antibodies. The assessment of rank probabilities indicated that reslizumab presented the greatest likelihood of having benefits for pulmonary function, reducing adverse events and improving AQLQ scores when compared with the placebo, and mepolizumab presented the best benefits for reducing asthmatic exacerbations. CONCLUSIONS Anti-interleukin-5 therapy appears to be a safe and effective treatment for asthma patients with respect to pulmonary lung function, adverse events and AQLQ scores, and do not increase asthmatic exacerbations. Our network meta-analysis in patients with asthma suggests that reducing adverse events benefits due to reslizumab, and pulmonary lung function benefits as well as good AQLQ scores are seen with respect to the three antibodies. Network meta-analysis indicates the probability that the best anti-interlukin-5 therapy for asthma patients might be reslizumab, but further trials are required to determine the most effective asthma treatment drug.

Abstract
Asthma is a chronic respiratory condition that is characterized by reversible airflow obstruction. Interleukin-5 (IL-5) is involved in the pathophysiology of the disease and drugs targeting IL-5 have been studied for years as a possible treatment option for severe asthma. In this review, the authors searched PubMed for major drug therapies and clinical trials against IL-5. A total of 29 articles met the criteria for selection and were shortlisted; of these, 10 papers were on benralizumab, 14 on mepolizumab, and five on reslizumab. The three drugs proved to be safe and efficacious for patients with severe asthma, leading to decreased rates of asthma exacerbations, lowered levels of eosinophils, and improved pulmonary functions in various studies. Patients also reported an improvement in the quality of life. The side effects of these three drugs were mild and no deaths directly linked to the drug were reported. However, longer duration studies are required to draw firm and strong conclusions on the safety of these therapeutic agents.

Abstract
BACKGROUND Several new biologics have been studied in patients with eosinophilic asthma with varying degrees of response on clinical outcomes. No head-to-head trial has directly compared the efficacy of these drugs. OBJECTIVE To synthesize data on the relative efficacy of benralizumab, dupilumab, lebrikizumab, mepolizumab, reslizumab, and tralokinumab using network meta-analysis. DATA SOURCES We searched PubMed from inception to December 15th, 2017. DATA EXTRACTION AND SYNTHESIS We used the 'frequentist' methodology with random effect models using primarily 'netmeta' function in R to generate network meta-analysis results. Outcomes assessed included changes in forced expiratory volume-in 1 s (FEV1), asthma control questionnaire (ACQ), and asthma quality of life questionnaire (AQLQ). We also separately analyzed the annualized rate ratios for asthma exacerbations for each drug and compared to placebo. For all outcomes assessed, all drugs were superior to placebo except tralokinumab. In terms of magnitude of effect, dupilumab, followed by reslizumab and benralizumab showed the greatest increase in FEV1, 0.16L (95% CIs: 0.08-0.24), 0.13L (0.10-0.17), and 0.12L (0.08-0.17), compared to placebo. While mepolizumab, followed by dupliumab, benralizumab, and reslizumab showed reductions in ACQ scores, in order of magnitude of effect, dupilumab, followed by mepolizumab, benralizumab, and reslizumab showed the greatest increase in AQLQ scores. All drugs decreased asthma exacerbations but the results were only significant for reslizumab and dupilumab. CONCLUSIONS All drugs except for tralokinumab showed improvements in FEV1, ACQ, and AQLQ. Only reslizumab and dupilumab were associated with statistically significant reductions in asthma exacerbation rates.

Abstract
INTRODUCTION Asthma is an airway disease characterized by airway inflammation. It is associated with significant morbidity, mortality, and costs to the health-care system and society. Eosinophils and interleukin-5 (IL-5) play a key role in the inflammatory response in T-helper 2-high asthma. IL-5 is pivotal for eosinophil development, maturation, and survival in tissues. Asthma severity has been related to both airway and peripheral blood eosinophilia. Areas covered: In this review, we present the pharmacokinetics and pharmacodynamics of benralizumab in addition to efficacy and safety data in the treatment of severe eosinophilic asthma. Expert commentary: Benralizumab is a potent biologic targeting the IL-5 receptor on eosinophils and basophils leading to depletion of target cells in peripheral blood and tissues. It is effective in reducing asthma exacerbations and has an oral corticosteroid-sparing effect in the treatment of asthma patients who are not controlled with medium-to-high-dose inhaled corticosteroids and long-acting beta agonists. The side effect profile is similar to placebo with the most reported adverse events being nasopharyngitis and worsened asthma in the pivotal trials. Its long-term safety is currently under investigation.

Abstract
Asthma is a very frequent chronic airway disease that includes many different clinical phenotypes and inflammatory patterns. In particular, eosinophilic bronchial inflammation is often associated with allergic as well as nonallergic asthma. The most important cytokine involved in the induction, maintenance, and amplification of airway eosinophilia in asthma is interleukin-5 (IL-5), released by both T helper 2 (Th2) lymphocytes and group 2 innate lymphoid cells (ILC2). Hence, IL-5 and its receptor are suitable targets for selective biologic drugs which can play a key role in add-on treatment of severe eosinophilic asthma refractory to corticosteroids. Within such a context, the anti-IL-5 monoclonal antibodies mepolizumab and reslizumab have been developed and approved for biological therapy of uncontrolled eosinophilic asthma. In this regard, on the basis of several successful randomized controlled trials, the anti-IL-5 receptor benralizumab has also recently obtained the approval from US Food and Drug Administration (FDA).

Abstract
Background Patients prefer at-home subcutaneous administration of biologics across different diseases, yet no biologic is approved for at-home use for severe, uncontrolled asthma. Objective We assessed at-home functionality, reliability, and performance of an accessorized pre-filled syringe (APFS) for subcutaneous benralizumab administration, an anti-eosinophil monoclonal antibody indicated for add-on maintenance treatment of patients with severe eosinophilic asthma. Materials and methods Patients (N=116) with severe, uncontrolled asthma despite receiving medium- or high-dosage inhaled corticosteroids and long-acting β2-agonists received up to 5 APFS-administered subcutaneous doses (Weeks 0, 4, 8, 12, and 16) of benralizumab 30 mg. The first 3 doses were administered at the study sites. The patient/caregiver administered the last 2 doses at home. Endpoints included the percentage of dispensed APFS that were used successfully blood eosinophil counts, Asthma Control Questionnaire 6, and safety. Results Nearly all dispensed APFS were successfully used in the clinic and at home (Week 0: 116/116, 100%; Week 4: 116/117, 99%; Week 8: 115/115, 100%; Week 12: 112/114, 98%; Week 16: 108/109, 99%). Only 1 APFS malfunctioned out of 573 dispensed. Two at-home administrations were unsuccessful because of patient-use error. One unreturned APFS was recorded as nonfunctional. Mean Asthma Control Questionnaire 6 scores decreased from baseline through all post-baseline time points, and nearly complete depletion of eosinophils was observed at the end of treatment. The most common adverse events were nasopharyngitis, upper respiratory tract infection, headache, and sinusitis. Five patients (4%) experienced transient mild or moderate injection-site reactions. Conclusion The APFS was functional, reliable, and performed equally well in the clinic and at home.

Abstract
Prostaglandin (PG) D2 is the ligand for the G-protein coupled receptors DP1 (D-type prostanoid receptor 1) and DP2 (also known as chemoattractant receptor homologous molecule, expressed on Th2 cells; CRTH2). Both, DP1 and DP2 are expressed on the cellular surface of eosinophils; although it has become quite clear that PGD2 induces eosinophil migration mainly via DP2 receptors, the role of DP1 in eosinophil responses has remained elusive. In this study, we addressed how DP1 receptor signaling complements the pro-inflammatory effects of DP2. We found that PGD2 prolongs the survival of eosinophils via a DP1 receptor-mediated mechanism that inhibits the onset of the intrinsic apoptotic cascade. The DP1 agonist BW245c prevented the activation of effector caspases in eosinophils and protected mitochondrial membranes from depolarization which-as a consequence-sustained viability of eosinophils. DP1 activation in eosinophils enhanced the expression of the anti-apoptotic gene BCL-XL , but also induced pro-inflammatory genes, such as VLA-4 and CCR3. In HEK293 cells that overexpress recombinant DP1 and/or DP2 receptors, activation of DP1, but not DP2, delayed cell death and stimulated proliferation, along with induction of serum response element (SRE), a regulator of anti-apoptotic, early-response genes. We conclude that DP1 receptors promote the survival via SRE induction and induction of pro-inflammatory genes. Therefore, targeting DP1 receptors, along with DP2, may contribute to anti-inflammatory therapy in eosinophilic diseases.

Abstract
Asthma is a widespread and heterogeneous inflammatory disease of the airways, which is characterized by several different phenotypes and endotypes. In particular, eosinophilic airway inflammation is a common pathologic trait of both allergic and nonallergic asthma. The key cytokine responsible for maturation, activation, recruitment, and survival of eosinophils is interleukin (IL)-5, which is mainly produced by T helper 2 (Th2) lymphocytes and group 2 innate lymphoid cells. Therefore, for uncontrolled patients with severe eosinophilic asthma, who are not fully responsive to corticosteroids, IL-5 represents a very important molecular target for add-on biological therapies. Among these new treatments, anti-IL-5 monoclonal antibodies such as mepolizumab and reslizumab have been developed and clinically evaluated. Furthermore, benralizumab is currently the only available biologic drug that specifically binds to the IL-5 receptor, thus preventing the interaction with its ligand and the consequent pro-inflammatory effects. The effectiveness of benralizumab in improving severe eosinophilic asthma has been well-documented by many randomized controlled trials.

Abstract
IL-5 is a key cytokine responsible for the maturation, recruitment and survival of eosinophils. The role of eosinophils in pathomechanisms of severe asthma and association of those cells with frequent exacerbations are well accepted. Novel biologic agents including anti-IL-5 antibodies (mepolizumab and reslizumab) as well as anti-IL-5 receptor α chain (benralizumab) have been developed. Benralizumab (Fasenra™) leads to reduced eosinophil counts in airway mucosa, blood, sputum and a clear inhibition of eosinophil differentiation and maturation in the bone marrow. In clinical studies, benralizumab significantly reduces the rate of asthma exacerbations and has a clear oral glucocorticoid sparing effect. The frequency and the type of reported adverse events do not differ between active treatment and placebo arms.

Abstract
CONTEXT Benralizumab is a humanized monoclonal antibody that targets the α chain of the IL-5 receptor (IL-5Rα) and is currently being assessed in clinical trials for asthma control. OBJECTIVE Our systematic review and meta-analysis intends to evaluate the therapeutic efficacy and safety of benralizumab in patients with eosinophilic asthma. DATA SOURCES AND EXTRACTION Literature searches of PubMed, Embase, and the Cochrane Library were performed to identify randomized controlled trials of benralizumab and clinic outcomes in asthmatics. RESULTS In total, 7 articles with 2,321 subjects met our inclusion criteria. From this pooled analysis, we found that benralizumab significantly reduces exacerbations (RR: 0.63, 95% CI: 0.52-0.76, p < 0.00001; I2 = 52%, p = 0.06) compared to placebo in eosinophilic asthma. There was no statistical trend for improvement in forced expiratory volume in 1 second or asthma control indices such as Quality of Life Assessment (AQLQ) and Asthma Control Questionnaire score in benralizumab-treated patients. In addition, safety data indicated that benralizumab administration resulted no increasing incidence of adverse events and was well tolerated (RR: 1.00, 95% CI: 0.95-1.05, p = 0.96; I2 = 40%, p = 0.13). CONCLUSION These results demonstrate the efficacy and safety of benralizumab for asthma patients with severe or uncontrolled symptoms and elevated eosinophils and provide support for benralizumab as an ideal option to treat asthma in this patient population.

Abstract
The goal of this series is to offer a survey of the latest literature for clinicians and scientists alike, providing a list of important recent advances relevant to the broad field of allergy and immunology. This particular assignment was to cover the topic of eosinophils. In an attempt to highlight major ideas, themes, trends, and advances relevant to basic and clinical aspects of eosinophil biology, a search of articles published since 2015 in the Journal of Allergy and Clinical Immunology and other high-impact journals was performed. Articles were then reviewed and organized, and then key findings were summarized. Given space limitations, many outstanding articles could not be included, but the hope is that what follows provides a succinct overview of recently published work that has significantly added to our knowledge of eosinophils and eosinophil-associated diseases.

Abstract
INTRODUCTION In many severe asthmatics, eosinophils cause inflammation and airways hyperresponsiveness, resulting in frequent exacerbations, impaired lung function, and reduced quality of life. Interleukin-5 (IL-5) is a key cytokine for eosinophil growth, differentiation, recruitment, activation, and survival. Anti-IL-5-based therapies (mepolizumab and reslizumab are humanized monoclonal antibodies (hmAbs) that recognize free IL-5, benralizumab is a hmAb directed at the α subunit of the IL-5R) target the IL-5-signaling in eosinophilic asthma. Areas covered: The pharmacodynamic/pharmacokinetic profile of benralizumab and how it provided indications that permitted optimization of the design and timelines of the pivotal trials are described. Expert opinion: Benralizumab has the advantage over other anti-IL-5 therapies to target the IL-5Rα itself. Afucosylation enhances its interaction with its binding site and facilitates its pharmacological activity. Other benefits of benralizumab are fast (within 24 h) depletion of peripheral blood eosinophils, potent suppressive activity of bone marrow eosinophils and eosinophil precursors, tissue eosinophil apoptosis regardless of the presence of eosinophil survival factors and even at low IL-5R densities. The fact that benralizumab is dosed subcutaneously and is equally effective when given every eight weeks instead than every four weeks provides patients with convenience of self-administration and make it appealing for patients who dislike injections.
