Abstract
Asthma is a common and burdensome chronic inflammatory airway disease that affects both children and adults. One of the main concerns with asthma is the manifestation of irreversible tissue remodelling of the airways due to the chronic inflammatory environment that eventually disrupts the whole structure of the airways. Most people with troublesome asthma are treated with inhaled corticosteroids. However, the development of steroid resistance is a commonly encountered issue, necessitating other treatment options for these patients. Biological therapies are a promising therapeutic approach for people with steroid-resistant asthma. Interleukin 5 is recently gaining a lot of attention as a biological target relevant to the tissue remodelling process. Since IL-5-neutralizing monoclonal antibodies (mepolizumab, reslizumab and benralizumab) are currently available for clinical use, this review aims to revisit the role of IL-5 in asthma pathogenesis at large and airway remodelling in particular, in addition to exploring its role as a target for biological treatments.

Abstract
Biologic therapies in asthma are indicated in severe disease, and they are directed against specific inflammatory modulators that contribute to pathogenesis and severity. Currently approved biologics target T2 cytokines (IgE, IL-5, IL-4/IL-13, and TLSP) and have demonstrated efficacy in clinical outcomes such as exacerbation rate and oral corticosteroid dose reductions, blood and airway eosinophil depletion, and lung function improvement. However, a proportion of these patients may show inadequate responses to biologics, with either initial lack of improvement or clinical and functional worsening after an optimal initial response. Exacerbations while on a biologic may be due to several reasons, including imprecise identification of the dominant effector pathway contributing to severity, additional inflammatory pathways that are not targeted by the biologic, inaccuracies of the biomarker used to guide therapy, inadequate dosing schedules, intercurrent airway infections, anti-drug neutralizing antibodies, and a novel phenomenon of autoimmune responses in the airways interfering with the effectiveness of the monoclonal antibodies. This review, illustrated using case scenarios, describes the underpinnings of airway autoimmune responses in driving exacerbations while patients are being treated with biologics, device a strategy to evaluate such exacerbations, an algorithm to switch between biologics, and perhaps to consider two biologics concurrently.

Abstract
Eosinophils are bi-lobed, multi-functional innate immune cells with diverse cell surface receptors that regulate local immune and inflammatory responses. Several inflammatory and infectious diseases are triggered with their build up in the blood and tissues. The mobilization of eosinophils into the lungs is regulated by a cascade of processes guided by Th2 cytokine generating T-cells. Recruitment of eosinophils essentially leads to a characteristic immune response followed by airway hyperresponsiveness and remodeling, which are hallmarks of chronic respiratory diseases. By analysing the dynamic interactions of eosinophils with their extracellular environment, which also involve signaling molecules and tissues, various therapies have been invented and developed to target respiratory diseases. Having entered clinical testing, several eosinophil targeting therapeutic agents have shown much promise and have further bridged the gap between theory and practice. Moreover, researchers now have a clearer understanding of the roles and mechanisms of eosinophils. These factors have successfully assisted molecular biologists to block specific pathways in the growth, migration and activation of eosinophils. The primary purpose of this review is to provide an overview of the eosinophil biology with a special emphasis on potential pharmacotherapeutic targets. The review also summarizes promising eosinophil-targeting agents, along with their mechanisms and rationale for use, including those in developmental pipeline, in clinical trials, or approved for other respiratory disorders.

Abstract
Abstract
Asthma is a heterogenous disease which pathophysiology is still poorly understood. Asthma was traditionally divided into allergic (extrinsic) and non-allergic (intrinsic) types, while patients with allergic type responded better to corticosteroids. Since 2013 the definition of asthma has changed. Recently, better insight into clinical consi -derations and underlying inflammatory phenotypes has been gained. Defining these phenotypes has already led to more specific clinical trials and, therefore, to more personalized and successfully targeted therapy. For future, much more effort is put in identifying new phenotype-specific biomarkers which could be helpful in stratification of heterogeneous patients with asthma.

Abstract
Improved understanding of the contribution of immune-inflammatory mechanisms in allergic diseases and asthma has encouraged development of biologicals and small molecules specifically targeting the innate and adaptive immune response. There are several critical points impacting the efficacy of this stratified approach, from the complexity of disease endotypes to the effectiveness in real-world settings. We discuss here how these barriers can be overcome to facilitate the development of implementation science for allergic diseases and asthma.

Abstract
ETHNOPHARMACOLOGICAL EVIDENCE Lepidii seu Descurainiae Semen (LDS) is used as a traditional herbal medicine in northeast Asia, mainly in Korea, Japan, and China to treat lung disorders including coughs and phlegm caused by acute and chronic airway inflammation. AIM OF THE STUDY Recently, interest regarding health problems incurred by air pollution has rapidly grown. Herbal medicines are being considered as alternative agents to treat various diseases. In the present study, we evaluated and compared the anti-inflammatory effects of LDS, which is derived from Lepidium apetalum Willd. extracts (LAE) and Descurainia sophia (L.) Webb ex Prantl extracts (DSE), on allergic airway inflammation. MATERIALS AND METHODS We established an ovalbumin-induced asthmatic mouse model to evaluate the efficacy of LDS extracts. We performed histological examination and measured relevant inflammatory mediators and cells in bronchoalveolar lavage fluid and lung. Furthermore, we conducted an in vitro T helper 2 (Th2) polarization assay, flow cytometry, and western blot analysis. RESULTS Asthmatic phenotypes were attenuated by LDS extract treatments. LDS extract administration significantly reduced mucus production, inflammatory cell infiltration into airways, and eosinophil activation. Furthermore, LDS extracts reduced the expression of type 2 cytokines and inhibited differentiation and activation of Th2 cells. CONCLUSION LDS alleviated eosinophilic inflammation by inhibiting Th2 cell differentiation, and DSE was more effective in attenuating allergic lung inflammation than LAE.

Abstract
Chronic eosinophilic pneumonia (CEP) is an eosinophilic lung disease that is typically diagnosed by a triad of clinical symptoms including pulmonary symptoms, eosinophilia and characteristic radiographic abnormalities. It requires a high index of suspicion given its overlap with other eosinophilic conditions and lack of a specific diagnostic test. The diagnosis is made after careful consideration of other secondary causes of eosinophilia, such as infectious, drugs, or toxic etiologies. CEP generally responds rapidly to treatment, which primarily consists of corticosteroid therapy, but relapses are common. Novel therapies are being explored as more information is being discovered about the pathophysiology of eosinophilic disease processes. Close follow-up is important given the difficulty in weaning patients from glucocorticoids with many patients developing sequelae of chronic glucocorticoid therapy. Therefore, exploring alternative treatments is of upmost importance.

Abstract
Approximately 5%–10% of asthmatics suffer from severe asthma. New biological treatments represent a great opportunity to reduce asthma burden and to improve asthma patients’ lives. Reslizumab will soon be available in several European countries. This anti-IL-5 IgG4/κ monoclonal antibody, administered intravenously at a dose of 3 mg/kg over 20–50 minutes every 4 weeks, has been shown to be safe and effective in patients with 400 eosinophils/μL or more in their peripheral blood. The clinical effects in reducing asthma exacerbations and in improving the quality of life and lung function are clear, but further research is needed to determine the best biological compound for a specific cluster of patients. Research data have shown that in patients who were expressing other clinical features of eosinophilic inflammation over asthma (rhinosinusitis and nasal polyposis), the clinical benefit of reslizumab was greater. Furthermore, it has also been observed that in patients with unsatisfactory response to mepolizumab, reslizumab is able to significantly improve the clinical and biological parameters. The aim of personalized medicine is to provide the right drug to the right patient at the right dose at the right moment. The biological treatments that were developed to modify specific pathological pathways not only provide us with the tools for the management of asthma patients but also clarify the biological mechanisms involved in its pathogenesis.

Abstract
BACKGROUND The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. AIMS To review, from an Infectious Diseases perspective, the safety profile of agents targeting interleukins, immunoglobulins and complement factors and to suggest preventive recommendations. SOURCES Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT Patients receiving interleukin-1 (IL-1) -targeted (anakinra, canakinumab or rilonacept) or IL-5-targeted (mepolizumab) agents have a moderate risk of infection and no specific prevention strategies are recommended. The use of IL-6/IL-6 receptor-targeted agents (tocilizumab and siltuximab) is associated with a risk increase similar to that observed with anti-tumour necrosis factor-α agents. IL-12/23-targeted agents (ustekinumab) do not seem to pose a meaningful risk of infection, although screening for latent tuberculosis infection may be considered and antiviral prophylaxis should be given to hepatitis B surface antigen-positive patients. Therapy with IL-17-targeted agents (secukinumab, brodalumab and ixekizumab) may result in the development of mild-to-moderate mucocutaneous candidiasis. Pre-treatment screening for Strongyloides stercoralis and other geohelminths should be considered in patients who come from areas where these are endemic who are receiving IgE-targeted agents (omalizumab). C5-targeted agents (eculizumab) are associated with a markedly increased risk of infection due to encapsulated bacteria, particularly Neisseria spp. Meningococcal vaccination and chemoprophylaxis must be administered 2-4 weeks before initiating eculizumab. Patients with high-risk behaviours and their partners should also be screened for gonococcal infection. IMPLICATIONS Preventive strategies are particularly encouraged to minimize the occurrence of neisserial infection associated with eculizumab.

Abstract
Current asthma treatments are effective for the majority of patients with mild-to-moderate disease. However, in those with more severe refractory asthma, agents other than inhaled corticosteroids and beta-agonists are needed both to better manage this group of patients and to avoid the side effects of high-dose corticosteroids and the social and personal hardship endured. Several biological pathways have been targeted over the last 20 years, and this research has resulted in pharmacological approaches to attempt to better treat patients with severe refractory asthma. The flagship of the biologics, the anti-IgE monoclonal antibody, omalizumab, has proven efficacious in selected subgroups of asthma patients. Tailoring asthma treatments to suit specific subtypes of asthma patients is in keeping with ideals of personalized medicine. Research in the complex interplay of allergens, epithelial host defenses, cytokines, and innate and adaptive immunity interactions has allowed better understanding of the mechanics of allergy and inflammation in asthma. As a result, new biologic treatments have been developed that target several different phenotypes and endotypes in asthma. As knowledge of the efficacy of these biological agents in asthma emerges, as well as the type of patients in whom they are most beneficial, the movement toward personalized asthma treatment will follow.

Abstract
OBJECTIVE To describe the concept of precision medicine in treating severe asthma and the utility of relevant biomarkers. DATA SOURCES PubMed was searched for published articles on human clinical trials using biologics for T-helper type 2 cell (TH2)-low and TH2-high asthma. STUDY SELECTIONS Studies were selected if they were double-masked, randomized, placebo-controlled trials published in peer-reviewed journals and relevant to the topic. RESULTS Multiple immune response modifiers have been evaluated in TH2-high asthma geared at blocking interleukin (IL)-5, IL-13, immunoglobulin E, prostaglandin D2, and other pathways. Currently, 3 immune response modifiers approved by the Food and Drug Administration are available for treating severe TH2-high asthma (1 anti-immunoglobulin E and 2 anti-IL-5 monoclonal antibodies) and other TH2-high therapies are in various stages of clinical development. Thus far, many of the TH2-high therapies have shown better efficacy when certain biomarkers are elevated, especially blood eosinophils. The TH2-low endotype does not have any readily available point-of-care biomarkers, so TH2-low asthma is often diagnosed based on a lack of TH2-high biomarkers. These patients tend to have greater resistance to steroids and the development of therapies has lagged behind that for TH2-high asthma. CONCLUSION Two major endotypes for asthma have been described, TH2-high, manifested by increased eosinophils in the sputum and airways of patients, and TH2-low, with increased neutrophils or a pauci-granulocytic profile. Using these classifications and specific biomarkers has led to promising new therapeutics, especially for TH2-high asthma.

Abstract
INTRODUCTION The classification of asthma into phenotypes and endotoypes allows for the use of targeted therapies, including three biologics which target interleukin 5 (IL-5) signaling in eosinophilic asthma. Areas covered: As of December 2016, two monoclonal antibodies, mepolizumab and reslizumab, are approved by U.S. Food and Drug Administration and one, benralizumab, is in clinical development. Two phase 3 trials for benralizumab, SIROCCO and CALIMA, were published in September 2016. Although there are no direct comparisons among these three anti-IL-5 therapies, the goal of this review is to summarize the current data and discuss their potential similarities and differences, with a focus on benralizumab. Expert commentary: Compared to mepolizumab and reslizumab, the possible advantages of benralizumab are less frequent dosing and a potential to reduce exacerbations irrespective of the blood eosinophil count. Some improvements in asthma symptom scores and quality of life occur with all three biologics, but the clinical meaningfulness of these improvements is less clear. A more defined reference range for eosinophil levels is necessary to determine which subjects will best benefit from these medications. Until quality randomized controlled trials directly compare the three, choosing among them for the treatment of eosinophilic asthma remains difficult.

Abstract
CONTEXT Reslizumab is a humanised anti-interleukin 5 monoclonal antibody that disrupts eosinophil maturation and promotes programmed cell death. OBJECTIVE We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug in patients with inadequately controlled, eosinophilic asthma. DATA SOURCES The search included the following databases: MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. STUDY SELECTION A literature review was performed to identify all published randomized double-blind, placebo-controlled trials of reslizumab for the treatment of inadequately controlled, eosinophilic asthma. DATA EXTRACTION Two reviewers independently extracted and verified pre-defined data fields. RESULTS Four publications including 5 RCTs that compared reslizumab with placebo. For the comparison of reslizumab with placebo, asthma exacerbation (odds ratio (OR) = 0.46, 95% confidence interval (CI) = 0.35 to 0.59, p <0.00001); a forced expiratory volume in 1 s (FEV1) (the standardized mean difference (SMD) = 0.16, 95%CI = 0.10 to 0.23, p <0.00001); Asthma Control Questionnaire (ACQ) score (the SMD = -0.26, 95%CI= -0.36 to -0.16, p <0.00001); blood eosinophil counts (the SMD = -475.62, 95%CI = -528.41 to -422.83, p <0.00001). Safety assessments included the proportion of individuals who withdrawn due to adverse event (AE) (OR = 0.60 95%CI = 0.38 to 1.17, p = 0.16) indicated that reslizumab was well tolerated. LIMITATIONS The article didn't research the safety, efficacy of reslizumab with longer term. CONCLUSIONS This meta-analysis indicates that reslizumab to be an effective and safe treatment for inadequately controlled, eosinophilic asthma.

Abstract
Within the context of the heterogeneous phenotypic stratification of asthmatic population, many patients are characterized by moderate-to-severe eosinophilic asthma, not adequately controlled by relatively high dosages of inhaled and even oral corticosteroids. Therefore, these subjects can obtain significant therapeutic benefits by additional biologic treatments targeting interleukin-5 (IL-5), given the key pathogenic role played by this cytokine in maturation, activation, proliferation, and survival of eosinophils. In particular, reslizumab is a humanized anti-IL-5 monoclonal antibody that has been found to be an effective and safe add-on therapy, capable of decreasing asthma exacerbations and significantly improving disease control and lung function in patients experiencing persistent allergic or nonallergic eosinophilic asthma, despite the regular use of moderate-to-high doses of inhaled corticosteroids. These important therapeutic effects of reslizumab, demonstrated by several controlled clinical trials, have led to the recent approval by US Food and Drug Administration of its use, together with other antiasthma medications, for the maintenance treatment of patients suffering from severe uncontrolled asthma.

Abstract
Asthma is a complex disorder frequently associated with a poor symptom control, concomitant morbidity, mortality, and significant health care costs due to lack of compliance or inadequate therapeutic options. Interleukin-5 (IL-5) plays a key role in the pathogenesis of eosinophilic disorders, and in the latest years has become a definite target for treatment. Besides asthma, other hypereosinophilic disorders include the hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, sinonasal polyposis, COPD with eosinophilic airway inflammation, allergic rhinitis, atopic dermatitis, eosinophilic esophagitis. The introduction of mepolizumab, a fully humanized monoclonal antibody that binds to IL-5, may represent a useful therapeutic option to control exacerbations and improve asthma-related quality of life in a subgroup of patients with persistent airway eosinophilia and moderate to severe asthma. Several studies carried out in recent years allow, at present, a careful patient selection for appropriate individualized treatment in severe asthma. Further research is anyway needed in order to better understand the pathogenetic mechanisms of asthma and to find new biomarkers. The high costs of biological agents as compared with standard drugs may be largely offset by increased clinical efficacy and good safety profile in selected patients.

Abstract
INTRODUCTION Patients with severe eosinophilic asthma have an unmet need for novel and efficacious treatments. Reslizumab is one of the three monoclonal antibodies targeting the IL-5 pathway and has been found in Phase IIIb clinical trials to reduce asthma exacerbations, control asthma-related symptoms and improve pulmonary function in patients with eosinophilic asthma. AREAS COVERED In this article, we discuss the results of asthma clinical trials using reslizumab, beginning with a discussion of the relationship between eosinophils, IL-5 and asthma. We conducted PubMed searches using the terms 'reslizumab', 'anti-IL-5', 'eosinophilic asthma', 'IL-5 asthma'. We also searched ClinicalTrials.gov for 'reslizumab', 'reslizumab asthma', 'SCH 55700', 'SCH 55700 asthma', 'Cinquil' and 'Cinquil asthma'. EXPERT OPINION Reslizumab and other anti-IL-5 therapies have seen success in recent trials through more stringent study participant selection targeting eosinophilic inflammation. This selection can now be based on simple blood counts. These drugs have shown a very good safety profile, but long-term safety data are not yet available. Approval for these drugs is eagerly awaited by clinicians and patients alike.
