Life (Basel) 2024; 14:899. [PMID: 39063652 PMCID: PMC11278432 DOI: 10.3390/life14070899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2024] [Revised: 07/12/2024] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Over the past 15 years, the paradigm of viewing the upper and lower airways as a unified system has progressively shifted the approach to chronic respiratory diseases (CRDs). As the global prevalence of CRDs continues to increase, it becomes evident that acknowledging the presence of airway pathology as an integrated entity could profoundly impact healthcare resource allocation and guide the implementation of pharmacological and rehabilitation strategies. In the era of precision medicine, endotyping has emerged as another novel approach to CRDs, whereby pathologies are categorized into distinct subtypes based on specific molecular mechanisms. This has contributed to the growing acknowledgment of a group of conditions that, in both the upper and lower airways, share a common type 2 (T2) inflammatory signature. These diverse pathologies, ranging from allergic rhinitis to severe asthma, frequently coexist and share diagnostic and prognostic biomarkers, as well as therapeutic strategies targeting common molecular pathways. Thus, T2 inflammation may serve as a unifying endotypic trait for the upper and lower airways, reinforcing the practical significance of the united airways model. This review aims to summarize the literature on the role of T2 inflammation in major CRDs, emphasizing the value of common biomarkers and integrated treatment strategies targeting shared molecular mechanisms.

Abstract
INTRODUCTION Chronic rhinosinusitis with nasal polyps (CRSwNP) is a prevalent inflammatory condition with heterogenous underlying endotypes, the most common being type 2 mediated inflammation. Several biologics have been developed to target specific pro-inflammatory cytokines and their receptors with proven efficacy in both quantitative and qualitative outcomes in patients with severe uncontrolled disease. However, there is an ongoing debate on the role of biologics relative to conventional therapies for CRSwNP and their efficacy in patient subgroups with non-polyp type 2 disease. AREAS COVERED This review examines the evidence on the efficacy and safety of biologics in CRSwNP, recommendations for their use, and discusses the broader economic factors influencing their application in clinical practice. EXPERT OPINION Emerging real-life data demonstrating the variable efficacy of the available biologics for patients with CRSwNP, coupled with the high cost compared to conventional therapies such as surgery, renders biologics to be considered as an add-on therapy in the majority of cases. However, ongoing research into increasing biologic dose intervals and novel therapies targeting alternative pathways may offer a more cost-effective and sustainable option in future.

Abstract
Monoclonal antibodies targeting interleukin (IL)-5 pathways have revolutionized the treatment expectations for eosinophilic-associated conditions, particularly in patients with respiratory involvement. Mepolizumab (IL-5 antagonist monoclonal antibody), benralizumab (IL-5 receptor blocker monoclonal antibody), and reslizumab (IL-5 antagonist monoclonal antibody) have collectively contributed to the overall improvement of the disease burden in various conditions. Eosinophilic asthma currently boasts the most robust evidence across all age groups: all three biologics are approved for adults (aged ≥18 years); mepolizumab is approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) also in children (aged ≥ 6 years), while bernalizumab was recently approved by the FDA for patients aged ≥6 years in the USA. In chronic rhinosinusitis with nasal polyps, subcutaneous mepolizumab is the only anti-IL-5 therapy approved so far and can be used in adult patients (aged ≥18 years). For eosinophilic esophagitis, conflicting evidence surrounds both mepolizumab, reslizumab, and benralizumab, leading to non-approval of these agents by the FDA/EMA. Recently, mepolizumab was approved for eosinophilic granulomatosis with polyangiitis patients aged ≥6 years or older and for hypereosinophilic syndrome adult patients. A phase III trial proving noninferiority of benralizumab versus mepolizumab in eosinophilic granulomatosis with polyangiitis has been recently published, while evidence on reslizumab is scant. Overall, current evidence on anti-IL-5 biologics for eosinophilic-associated disorders is mostly focused on adults, whereas data for individuals aged under 18 years and over 65 years are scarce, resulting in a lack of evidence, particularly regarding efficacy, for the use of anti-IL-5 agents in these specific patient populations. This review addresses high-quality evidence from randomized controlled trials and real-world post-marketing studies regarding the use of anti-IL-5 therapies for eosinophilic-associated disorders across all age groups, spanning childhood, adulthood, and older age.

Abstract
INTRODUCTION Biologic therapies for Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) have emerged as an auspicious treatment alternative. However, the ideal patient population, dosage, and treatment duration are yet to be well-defined. Moreover, biologic therapy has disadvantages, such as high costs and limited access. The proposal of a novel Artificial Intelligence (AI) algorithm offers an intriguing solution for optimizing decision-making protocols. METHODS The AI algorithm was initially programmed to conduct a systematic literature review searching for the current primary guidelines on biologics' clinical efficacy and safety in treating CRSwNP. The review included a total of 12 studies: 6 systematic reviews, 4 expert consensus guidelines, and 2 surveys. Simultaneously, two independent human researchers conducted a literature search to compare the results. Subsequently, the AI was tasked to critically analyze the identified papers, highlighting strengths and weaknesses, thereby creating a decision-making algorithm and pyramid flow chart. RESULTS The studies evaluated various biologics, including monoclonal antibodies targeting Interleukin-5 (IL-5), IL-4, IL-13, and Immunoglobulin E (IgE), assessing their effectiveness in different patient populations, such as those with comorbid asthma or refractory CRSwNP. Dupilumab, a monoclonal antibody targeting the IL-4 receptor alpha subunit, demonstrated significant improvement in nasal symptoms and quality of life in patients with CRSwNP in several randomized controlled trials and systematic reviews. Similarly, mepolizumab and reslizumab, which target IL-5, have also shown efficacy in reducing nasal polyp burden and improving symptoms in patients with CRSwNP, particularly those with comorbid asthma. However, additional studies are required to confirm the long-term efficacy and safety of these biologics in treating CRSwNP. CONCLUSIONS Biologic therapies have surfaced as a promising treatment option for patients with severe or refractory CRSwNP; however, the optimal patient population, dosage, and treatment duration are yet to be defined. The application of AI in decision-making protocols and the creation of therapeutic algorithms for biologic drug selection, could offer fascinating future prospects in the management of CRSwNP.

Association Between T2-related Comorbidities and Effectiveness of Biologics in Severe Asthma. Am J Respir Crit Care Med 2024; 209:262-272.

Abstract
Rationale: Previous studies investigating the impact of comorbidities on the effectiveness of biologic agents have been relatively small and of short duration and have not compared classes of biologic agents. Objectives: To determine the association between type 2-related comorbidities and biologic agent effectiveness in adults with severe asthma (SA). Methods: This cohort study used International Severe Asthma Registry data from 21 countries (2017-2022) to quantify changes in four outcomes before and after biologic therapy-annual asthma exacerbation rate, FEV1% predicted, asthma control, and long-term oral corticosteroid daily dose-in patients with or without allergic rhinitis, chronic rhinosinusitis (CRS) with or without nasal polyps (NPs), NPs, or eczema/atopic dermatitis. Measurements and Main Results: Of 1,765 patients, 1,257, 421, and 87 initiated anti-IL-5/5 receptor, anti-IgE, and anti-IL-4/13 therapies, respectively. In general, pre- versus post-biologic therapy improvements were noted in all four asthma outcomes assessed, irrespective of comorbidity status. However, patients with comorbid CRS with or without NPs experienced 23% fewer exacerbations per year (95% CI, 10-35%; P < 0.001) and had 59% higher odds of better post-biologic therapy asthma control (95% CI, 26-102%; P < 0.001) than those without CRS with or without NPs. Similar estimates were noted for those with comorbid NPs: 22% fewer exacerbations and 56% higher odds of better post-biologic therapy control. Patients with SA and CRS with or without NPs had an additional FEV1% predicted improvement of 3.2% (95% CI, 1.0-5.3; P = 0.004), a trend that was also noted in those with comorbid NPs. The presence of allergic rhinitis or atopic dermatitis was not associated with post-biologic therapy effect for any outcome assessed. Conclusions: These findings highlight the importance of systematic comorbidity evaluation. The presence of CRS with or without NPs or NPs alone may be considered a predictor of the effectiveness of biologic agents in patients with SA.

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

Benralizumab in severe eosinophilic asthma in real life: confirmed effectiveness and contrasted effect on sputum eosinophilia versus exhaled nitric oxide fraction - PROMISE. ERJ Open Res 2023; 9:00383-2023. [PMID: 38020567 PMCID: PMC10680030 DOI: 10.1183/23120541.00383-2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Accepted: 09/25/2023] [Indexed: 12/01/2023] Open
Abstract
Background Randomised controlled trials have shown that benralizumab, an anti-interleukin-5 receptor monoclonal antibody, reduces exacerbations and oral corticosteroid dose and improves asthma control and lung function in severe eosinophilic asthma. The aim of this study was to confirm results of randomised controlled trials in real life in a population of 73 patients with severe eosinophilic asthma treated with benralizumab for at least 12 months. Methods Patients underwent careful monitoring of asthma exacerbations, exhaled nitric oxide fraction, lung function, asthma control and quality of life questionnaire responses and sputum induction, and gave a blood sample at baseline, after 6 months and then every year. Results We found significant reductions in exacerbations (by 92%, p<0.0001) and oral corticosteroid dose (by 83%, p<0.001) after 6 months that were maintained over time, with 78% of patients able to stop oral corticosteroid therapy. Patients improved their Asthma Control Test (ACT) score (from 11.7±5.1 to 16.9±5.35, p<0.0001), Asthma Control Questionnaire (ACQ) score (from 2.88±1.26 to 1.77±1.32, p<0.0001) and Asthma Quality of Life Questionnaire score (+1.04, p<0.0001) at 6 months and this was maintained during follow-up. Only 35% and 43% of patients reached asthma control according to an ACT score ≥20 and ACQ score <1.5, respectively. We observed stable post-bronchodilation lung function over time and a significant reduction in sputum eosinophil count, with 85% of patients exhibiting sputum eosinophil counts <3% after 6 months (p<0.01) with no effect on exhaled nitric oxide fraction. Conclusion In our real-life study, we confirm the results published in randomised controlled trials showing a sharp reduction in exacerbations and oral corticosteroid therapy, an improvement in asthma control and quality of life, and a dramatic reduction in sputum eosinophil count.

The Unified Airway Hypothesis: Evidence From Specific Intervention With Anti-IL-5 Biologic Therapy. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:2630-2641.

Abstract
The unified airway hypothesis proposes that upper and lower airway diseases reflect a single pathological process manifesting in different locations within the airway. Functional, epidemiological, and pathological evidence has supported this well-established hypothesis for some time. However, literature on the pathobiologic roles/therapeutic targeting of eosinophils and IL-5 in upper and lower airway diseases (including asthma, chronic rhinosinusitis with nasal polyps [CRSwNP], and nonsteroidal anti-inflammatory drug-exacerbated respiratory disease) has recently emerged. This narrative review revisits the unified airway hypothesis by searching the scientific literature for recent learnings and clinical trial/real-world data that provide a novel perspective on its relevance for clinicians. According to the available literature, eosinophils and IL-5 have important pathophysiological roles in both the upper and lower airways, although the impact of eosinophils and IL-5 may vary in asthma and CRSwNP. Some differential effects of anti-IL-5 and anti-IL-5-receptor therapies in CRSwNP have been observed, requiring further investigation. However, pharmaceutical targeting of eosinophils and IL-5 in patients with upper, lower, and comorbid upper and lower airway inflammation has led to clinical benefit, supporting the hypothesis that these are linked conditions manifesting in different locations. Consideration of this approach may improve patient care and aid clinical decision making.

Abstract
Difficult-to-treat and severe asthma are challenging clinical entities. In the face of suboptimal asthma control, the temptation for clinicians is to reflexively escalate asthma-directed therapy, including increasing exposure to corticosteroids and commencement of costly but potent biologic therapies. However, asthma control is objectively and subjectively assessed based on measurable parameters (such as exacerbations or variability in pulmonary physiology), symptoms and patient histories. Crucially, these features can be confounded by common untreated comorbidities, affecting clinicians' assessment of asthma treatment efficacy.

Abstract
INTRODUCTION Chronic sinusitis with nasal polyposis (CRSwNP) is a common heterogeneous disease that mainly manifests as chronic inflammation of the sinus mucosa. The effect of conventional treatments for CRSwNP, such as oral corticosteroids, intranasal corticosteroids (INCS) and polypectomy, is not always obvious, and postoperative recurrence is common in some CRSwNP patients. In recent years, some biologics have been shown to be very effective in treating refractory CRSwNP, of which dupilumab has attracted much attention as the first monoclonal drug approved to treat nasal polyps. AREAS COVERED In this review, we discuss the research status of dupilumab in treatment of CRSwNP and how dupilumab differs from other treatment methods. EXPERT OPINION The European Union and United States have approved dupilumab as the first biological agent for treatment of CRSwNP. Dupilumab can improve symptoms of nasal congestion or obstruction, nasal secretion, and olfactory loss in patients with CRSwNP. It can also improve a patient's health-related quality of life (HR-QoL) and reduce the need for systemic corticosteroids and nasal polyp surgery. While subcutaneous injection of dupilumab is a novel method for treating CRSwNP, it is still necessary to reasonably evaluate which patients might benefit most from biological therapy.

Abstract
INTRODUCTION In recent years, endotypes of chronic rhinosinusitis (CRS) based on the underlying immune mechanisms provided a better understanding of this heterogeneous disease and are frequently applied in diagnosis and treatment. AREAS COVERED In this manuscript, we aim to review novel treatment approaches for this often uncontrolled disease and highlight endotype-driven medical algorithms that could be beneficial in daily clinical practice. EXPERT OPINION With the development of endotyping and the mucosal inflammatory concept, several type 2-targeted biologics and surgical options are nowadays available for treating CRS. However, a better understanding based on clinical trials and real-life experience in daily practice is needed to optimize patient selection, biological drug selection, treatment duration, prediction, and long-term follow-up strategies. Indirect comparison analysis suggested that dupilumab might be the most effective biologic for treating CRS with nasal polyps, but the role and timing of surgery remain unclear. More real-life studies and comparative trials are needed for the optimal integration of biologics into clinical pathways in combination with established treatment approaches such as nasal and oral glucocorticosteroids and adequate surgery to provide long-term perspectives.

Abstract
"Epidemiology of comorbidities and their association with asthma control" (Tomisa, G., Horváth, A., Sánta, B. et al. Epidemiology of comorbidities and their association with asthma control. Allergy Asthma Clin Immunol 17, 95 (2021). https://doi.org/10.1186/s13223-021-00598-3 ) is an interesting paper reflecting data collection from more than 12,000 asthmatic patients in Hungary regarding their condition and associated comorbidities. We found it valuable that the paper provides an overview of asthma comorbidities not usually considered in similar reports. Nevertheless, we believe that chronic rhinosinusitis (CRS) with or without nasal polyps (CRSwNP or CRSsNP) should have been listed due to its high incidence and prevalence, its association with asthma which is also endorsed in both GINA and EPOS, as well as in several peer-reviewed scientific papers, and to reflect the role of this comorbidity in poor control and a most severe presentation of asthma for the patient. Consequently, several targeted therapies (especially monoclonal antibodies) used for several years in severe forms of asthma are now indicated also for the effective treatment of nasal polyps.

Abstract
The last decade has seen significant developments in the field of biologics for the treatment of chronic rhinosinusitis with nasal polyps (CRSwNP). Translational research borne from knowledge of the pathophysiology of type 2 inflammatory disease of the lower airways and the strong association with CRSwNP, has led to major therapeutic breakthroughs, with phase 3 trials of four biologics completed at the time of writing, and more underway. This article explores the evidence behind biologics for CRSwNP, the guidance on their use and the health economic factors influencing their position amongst the established therapeutic options for this common chronic condition.

Abstract
BACKGROUND In clinical and epidemiological studies, cutoffs of patient-reported outcome measures can be used to classify patients into groups of statistical and clinical relevance. However, visual analog scale (VAS) cutoffs in MASK-air have not been tested. OBJECTIVE To calculate cutoffs for VAS global, nasal, ocular, and asthma symptoms. METHODS In a cross-sectional study design of all MASK-air participants, we compared (1) approaches based on the percentiles (tertiles or quartiles) of VAS distributions and (2) data-driven approaches based on clusters of data from 2 comparators (VAS work and VAS sleep). We then performed sensitivity analyses for individual countries and for VAS levels corresponding to full allergy control. Finally, we tested the different approaches using MASK-air real-world cross-sectional and longitudinal data to assess the most relevant cutoffs. RESULTS We assessed 395,223 days from 23,201 MASK-air users with self-reported allergic rhinitis. The percentile-oriented approach resulted in lower cutoff values than the data-driven approach. We obtained consistent results in the data-driven approach. Following the latter, the proposed cutoff differentiating "controlled" and "partly-controlled" patients was similar to the cutoff value that had been arbitrarily used (20/100). However, a lower cutoff was obtained to differentiate between "partly-controlled" and "uncontrolled" patients (35 vs the arbitrarily-used value of 50/100). CONCLUSIONS Using a data-driven approach, we were able to define cutoff values for MASK-air VASs on allergy and asthma symptoms. This may allow for a better classification of patients with rhinitis and asthma according to different levels of control, supporting improved disease management.

Long-term efficacy of dupilumab in asthma with or without chronic rhinosinusitis and nasal polyps. Ann Allergy Asthma Immunol 2023; 130:215-224. [PMID: 36356712 DOI: 10.1016/j.anai.2022.11.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 10/21/2022] [Accepted: 11/02/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Coexisting chronic rhinosinusitis and nasal polyps (CRS-NPs) substantially increases the disease burden of asthma. Dupilumab, a fully human monoclonal antibody, has established efficacy and an acceptable safety profile in asthma and CRS with NP. OBJECTIVE To evaluate long-term dupilumab efficacy in TRAVERSE (NCT02134028) patients with uncontrolled, moderate-to-severe (QUEST) or oral corticosteroid (OCS)-dependent (VENTURE) asthma with or without coexisting CRS-NP. METHODS In TRAVERSE, 317 of 1530 (21%) QUEST and 61 of 187 (48%) VENTURE patients had self-reported CRS-NP; they received subcutaneous 300 mg dupilumab every 2 weeks up to 96 weeks. Patients were categorized by parent study treatment group (placebo/dupilumab, dupilumab/dupilumab). End points included annualized asthma exacerbation rates and mean change from parent study baseline in prebronchodilator forced expiratory volume in 1 second, Asthma Control Questionnaire 5 score, Asthma Quality of Life Questionnaire score, and OCS dose. RESULTS Patients with coexisting CRS-NP had higher OCS dose and a history of more exacerbations. Concluding TRAVERSE, exacerbation rates decreased from 2.39 to 0.32 and 2.32 to 0.35 in dupilumab/dupilumab and 2.36 to 0.41 and 2.36 to 0.45 in placebo/dupilumab by week 96 from QUEST and VENTURE baselines, respectively. Non-CRS-NP results were similar. Improvements in forced expiratory volume in 1 second, Asthma Control Questionnaire 5 score, and Asthma Quality of Life Questionnaire score during parent studies were maintained in TRAVERSE; placebo/dupilumab patients achieved similar improvements to dupilumab/dupilumab by week 48. By week 96, 71% and 39% of OCS-dependent patients with CRS-NP and 83% and 47% without CRS-NP treated with dupilumab/dupilumab and placebo/dupilumab, respectively, stopped OCS. CONCLUSION Long-term dupilumab efficacy was maintained in patients with asthma with or without self-reported coexisting CRS-NP, including OCS-sparing effects observed in OCS-dependent severe asthma. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov Identifiers: NCT02528214, NCT02414854, and NCT02134028.

Abstract
BACKGROUND Comparative effectiveness research between endoscopic sinus surgery (ESS) and biologic therapy for severe chronic rhinosinusitis with nasal polyposis (CRSwNP) is a nascent field as new therapeutic modalities become clinically available. METHODS A prospective, multicenter cohort of CRSwNP patients, undergoing ESS between 2011 and 2019, were compared to phase-3 biologic trial data. Patients undergoing ESS received baseline nasal endoscopy quantified via Lund-Kennedy (LK) grading. Patients meeting inclusion criteria, modified from Dupilumab-LIBERTY-NP-24&52, omalizumab-POLYP-1&2, and Mepolizumab-SYNAPSE clinical trials, were included in this study. Baseline characteristics and outcome measures were compared between these cohorts at 24 weeks and 52 weeks, when possible. RESULTS A total of 111 CRSwNP patients met modified inclusion criteria. There were no statistically significant differences in baseline age, sex, asthma status, aspirin-exacerbated respiratory disease status, smell identification, LK-polyp score, and Lund-Mackay computed tomography (CT) scores between ESS and biologic groups. At 24 weeks, ESS demonstrated significantly greater improvements in 22-item Sino-Nasal Outcome Test (SNOT-22) compared to one (of two) dupilumab trials (p < 0.05) and both omalizumab trials (p < 0.001). ESS associated with significantly lower nasal polyp scores (NPS) compared to dupilumab (p < 0.001) and omalizumab (p < 0.001), despite comparable improvements in smell identification (p > 0.05). At 52 weeks, ESS resulted in statistically similar improvement in SNOT-22 scores compared to dupilumab (p = 0.21), but NPS remained significantly lower in the ESS group compared to dupilumab (p < 0.001) and mepolizumab (p < 0.001). CONCLUSION At 24 weeks and 52 weeks, ESS offers comparable SNOT-22 improvements compared to dupilumab. ESS and dupilumab offer comparable improvement in smell identification at 24 weeks. Compared to omalizumab, ESS offers superior SNOT-22 improvements. ESS offers significantly greater reductions in polyp size compared to omalizumab, dupilumab, and mepolizumab therapies.

Abstract
Chronic rhinosinusitis (CRS) with nasal polyps is the most severe form of inflammatory diseases of the paranasal sinuses, especially in combination with comorbid asthma. A new avenue for the personalized treatment of severe forms of eosinophilic inflammation are biologics based on humanized monoclonal antibodies. OBJECTIVE To study the effectiveness of targeted therapy in patients with CRS with nasal polyps and comorbid asthma. MATERIAL AND METHODS 19 patients selected for biological therapy according to international criteria were studied. The patients were randomly divided into 2 groups. The first group included 10 patients treated with dupilumab. Dupilumab was administered subcutaneously 300 mg every 2 weeks for 24 weeks. Group 2 included 9 patients treated with reslizumab for severe eosinophilic asthma with comorbid CRS with nasal polyps. Reslizumab was administered intravenously 3 mg/kg body weight once every 4 weeks for 24 weeks. These patients constituted the comparison group. Both drugs are used in treatment of eosinophilic inflammation but have different biological targets. RESULTS Comparative analysis of the dynamics of the main indicators characterizing the clinical course of CRS with nasal polyps and asthma (SNOT-22, control of asthma symptoms - ACT, the results of SCT of the paranasal sinuses according to the Lund-Mackay score) revealed a positive trend in patients of both groups, more pronounced in patients receiving dupilumab. CONCLUSION Changes in CT of the paranasal sinuses, characterized by the Lund-Mackay score, the results of SNOT-22 and ACT are the most demonstrative and can be used to assess the results of treatment with biologics in patients with chronic rhinosinusitis with nasal polyps.

Abstract
INTRODUCTION A clear understanding of the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP) and its close association with other airway pathologies, especially asthma, helps to comprehend the concept of the united airway and the importance of a multidisciplinary approach and the actual roll of biologic therapy. AREAS COVERED This expert review is the synthesis of a working group on the current state of the art of the evaluation and management of CRSwNP. A thorough analysis of the literature has been conducted for the latest studies and results, specially the European (EPOS 2020) and American (ICAR-RS 2021) guidelines. EXPERT OPINION The roles of optimal medical treatment and indications for surgery are becoming clearer, but much research is still needed regarding the extent and radicality when surgery is indicated. The main objectives of this review were to provide a clear and updated description of treatments, their indication, follow-up, and response criteria. These steps are considering the broad spectrum of inflammation endophenotypes and the biologic therapy available. Understanding the role and limitations of each specialty is key for providing greatest benefit to the patient.

Abstract
Objective: To review published literature for biologic treatment of nasal polyps. Data Sources: PubMed search performed on February 16, 2022, using search terms: biologics, benralizumab, dupilumab, mepolizumab, omalizumab, or reslizumab AND nasal polyps, nasal polyposis, or chronic rhinosinusitis with nasal polyposis (CRSwNP). Inclusion criteria were English language, published randomized controlled trials, post hoc analyses, and meta-analyses evaluating biologics for nasal polyposis, with or without comorbid asthma, and no date limits. Additional studies were found through references of primary and tertiary literature. Study Selection and Data Extraction: Nineteen studies, including 8 randomized controlled trials, 2 meta-analyses, and 9 post hoc analyses, examined the efficacy and safety of biologics for nasal polyposis. Agents studied included benralizumab, dupilumab, mepolizumab, omalizumab, and reslizumab. Studies had similar inclusion (refractory and recurrent CRSwNP) and exclusion criteria. All studies included the use of an intranasal corticosteroid (mometasone or fluticasone) in addition to the biologic or placebo. The most commonly studied primary endpoint was change in endoscopic nasal polyp score. Data Synthesis: All studies, post hoc analyses, and meta-analyses found improvement in endoscopic, clinical, and/or radiographic endpoints with benralizumab, dupilumab, mepolizumab, omalizumab, or reslizumab in patients with CRSwNP with or without comorbid asthma. Dupilumab has the most published data. Dupilumab, mepolizumab, and omalizumab are the only biologics currently Food and Drug Administration-approved for CRSwNP. Conclusion: Biologics are beneficial for treating nasal polyps with or without comorbid asthma. The choice depends on patient and provider preference and insurance coverage.

Abstract
Chronic inflammatory airway diseases, including asthma, chronic rhinosinusitis, eosinophilic COPD and allergic rhinitis are a global health concern. Despite the coexistence of these diseases and their common pathophysiology, they are often managed independently, resulting in poor asthma control, continued symptoms and poor quality of life. Understanding disease pathophysiology is important for best treatment practice, reduced disease burden and improved patient outcomes. The pathophysiology of type 2 inflammation is driven by both the innate immune system triggered by pollutants, viral or fungal infections involving type 2 innate lymphoid cells (ILC2) and the adaptive immune system, triggered by contact with an allergen involving type 2 T-helper (Th2) cells. Both ILC2 and Th2 cells produce the type-2 cytokines (interleukin (IL)-4, IL-5 and IL-13), each with several roles in the inflammation cascade. IL-4 and IL-13 cause B-cell class switching and IgE production, release of pro-inflammatory mediators, barrier disruption and tissue remodelling. In addition, IL-13 causes goblet-cell hyperplasia and mucus production. All three interleukins are involved in trafficking eosinophils to tissues, producing clinical symptoms characteristic of chronic inflammatory airway diseases. Asthma is a heterogenous disease; therefore, identification of biomarkers and early targeted treatment is critical for patients inadequately managed by inhaled corticosteroids and long-acting β-agonists alone. The Global Initiative for Asthma guidelines recommend add-on biological (anti IgE, IL-5/5R, IL-4R) treatments for those not responding to standard of care. Targeted therapies, including omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab and tezepelumab, were developed on current understanding of the pathophysiology of type 2 inflammation. These therapies offer hope for improved management of type 2 inflammatory airway diseases.

Abstract
Effective treatment of inflammatory diseases is often challenging owing to their heterogeneous pathophysiology. Understanding of the underlying disease mechanisms is improving and it is now clear that eosinophils play a complex pathophysiological role in a broad range of type 2 inflammatory diseases. Standard of care for these conditions often still includes oral corticosteroids (OCS) and/or cytotoxic immune therapies, which are associated with debilitating side effects. Selective, biological eosinophil‐reducing agents provide treatment options that improve clinical symptoms associated with eosinophilic inflammation and reduce OCS use. Mepolizumab is a humanized monoclonal antibody that binds to and neutralizes interleukin‐5, the major cytokine involved in eosinophil proliferation, activation, and survival. Mepolizumab is approved for the treatment of severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis and hypereosinophilic syndrome. Additionally, the efficacy of add‐on mepolizumab has been observed in patients with severe chronic rhinosinusitis with nasal polyposis and chronic obstructive pulmonary disease with an eosinophilic phenotype. Here, we review the development, approval, and real‐world effectiveness of mepolizumab for the treatment of patients with severe eosinophilic asthma, from the DREAM to REALITI‐A studies, and describe how knowledge from this journey extended to the use of mepolizumab and other biologics across a broad spectrum of eosinophilic diseases.

Estimating Clinically Meaningful Change of Efficacy Outcomes in Inadequately Controlled Chronic Rhinosinusitis with Nasal Polyposis. Laryngoscope 2022; 132:265-271. [PMID: 34850966 PMCID: PMC9299621 DOI: 10.1002/lary.29888] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 09/16/2021] [Accepted: 09/21/2021] [Indexed: 01/02/2023]
Abstract
OBJECTIVES/HYPOTHESIS Clinical trials of biologics to treat chronic rhinosinusitis with nasal polyposis (CRSwNP) have evaluated objective outcomes (e.g., University of Pennsylvania Smell Identification Test [UPSIT], nasal polyps score [NPS], and computed tomography Lund-Mackay score [CT-LMK]) and patient-reported symptoms (e.g., nasal congestion/obstruction [NC], loss of smell [LoS], and total symptom score [TSS]). We estimated anchor-based thresholds for clinically meaningful change in objective and patient-reported outcomes in patients with CRSwNP using data from LIBERTY NP SINUS-24 and SINUS-52 trials (NCT02912468; NCT02898454). METHODS Target patient-reported outcomes were NC, LoS, and TSS; target objective outcomes were UPSIT, NPS, and CT-LMK. Anchor measures were the 22-item sinonasal outcome test (SNOT-22) rhinologic symptoms domain and total score and rhinosinusitis visual analog scale (VAS). The appropriateness of each anchor measure was evaluated by reviewing correlations between change in anchor measures and target outcomes and descriptive scores on target outcomes by levels of change in the anchor measure. Established thresholds for anchor measures (3.8 points for SNOT-22 rhinologic symptoms, 8.9 points for SNOT-22 total, 1-category improvement for rhinosinusitis VAS) were used to estimate clinically meaningful score changes for each target outcome. RESULTS Based on correlations between change in anchor measures and target outcomes, SNOT-22 rhinologic symptoms domain was deemed the most appropriate anchor measure. Using this anchor measure, thresholds for clinically meaningful within-patient change were NC: 1 point; LoS: 1 point; TSS: 3 points; UPSIT: 8 points; NPS: 1 point; and CT-LMK: 5 points. CONCLUSION These thresholds support interpretation of efficacy results for target outcomes in CRSwNP trials. LEVEL OF EVIDENCE 2 Laryngoscope, 132:265-271, 2022.

Abstract
Recent developments in therapeutic strategies have provided alternatives to corticosteroids as the cornerstone treatment for managing airway inflammation in asthma. The past two decades have witnessed a tremendous boost in the development of anti-cytokine monoclonal antibody (mAb) therapies for the management of severe asthma. Novel biologics that target eosinophilic inflammation (or type 2, T2 inflammation) have been the most successful at treating asthma symptoms, though there are a few in the drug development pipeline for treating non-eosinophilic or T2-low asthma. There has been significant improvement in clinical outcomes for asthmatics treated with currently available monoclonal antibodies (mAbs), including anti-immunoglobulin (Ig) E, anti-interleukin (IL)-4 receptor α subunit, anti-IL-5, anti-IL-5Rα, anti-IL-6, anti-IL-33, and anti-thymic stromal lymphopoietin (TSLP). Despite these initiatives in precision medicine for asthma therapy, a significant disease burden remains, as evident from modest reduction of exacerbation rates, i.e., approximately 40-60%. There are numerous studies that highlight predictors of good responses to these biologics, but few have focused on those who fail to respond adequately despite targeted treatment. Phenotyping asthmatics based on blood eosinophils is proving to be inadequate for choosing the right drug for the right patient. It is therefore pertinent to understand the underlying immunology, and perhaps, carry out immune endotyping of patients before prescribing appropriate drugs. This review summarizes the immunology of asthma, the cytokines or receptors currently targeted, the possible mechanisms of sub-optimal responses, and the importance of determining the immune make-up of individual patients prior to prescribing mAb therapy, in the age of precision medicine for asthma.

Abstract
The study was conducted to evaluate the effectiveness of an asthma educational program for asthma control, asthma self-management, asthma knowledge, and patient activation. The study analyzes different demographic variables with the purpose of investigating which asthma patients performed better than others. Based on these demographic characteristics, the study provides several recommendations for various stakeholders. The study is based on a positivist approach since its purpose is to investigate the consequences of an asthma educational program with a view to generalizing the results to a larger population. The study targets public and private hospitals which have applied the asthma educational program in collaboration with the Saudi Initiative for Asthma (SINA). Multiple questionnaires were deployed 263 valid responses were received from patients of public and private hospitals using online and offline data collection method. Several parametric and non-parametric tests were carried out in terms of data analysis. The results reveal that patients in the intervention group obtained high scores and were therefore more knowledgeable and able to control their asthma compared to the control group. Overall, patients in the intervention group performed better in terms of asthma control, asthma self-management and knowledge and awareness. There was a high level of patient activation in this group. In the context of demographic features, it was found that patients who are married and are undergraduate degree holders in employment scored high compared to patients who were young, single, post-graduate degree holders that were mainly self-employed. The results of this study can guide policy makers, SINA authorities, and hospitals as to which demographic category of asthma patients require immediate attention. The significance of asthma educational programmes has increased especially through social media platforms as the number of adult patients continues to increase day by day.

Abstract
Aspirin-exacerbated respiratory disease (AERD) is a condition composed of chronic rhinosinusitis with nasal polyposis and asthma that is defined by respiratory hypersensitivity reactions to the cyclooxygenase 1-inhibitory effects of nonsteroidal anti-inflammatory drugs. It is diagnosed in 5% to 15% of patients with asthma and is even more common in those with comorbid nasal polyposis. Diagnosis is confirmed after an aspirin challenge procedure, yet many patients present with all components and can reliably be diagnosed by history. Patients with AERD commonly experience severe uncontrolled nasal polyposis and require multispecialty evaluation to properly stage and treat this condition. The presence of nasal polyposis plays a large component in the diminished quality of life in patients with AERD. In the last decade, multiple new therapeutic areas have been approved for type 2 airway diseases, offering patients with AERD many more options for control. This makes an early and accurate diagnosis of AERD important in the care of the larger population of type 2 airway diseases.

Abstract
Asthma has been increasingly recognized as being a heterogeneous disease with multiple distinct mechanisms and pathophysiologies. Evidence continues to build regarding the existence of different cell types, environmental exposures, pathogens, and other factors that produce a similar set of symptoms known collectively as asthma. This has led to a movement from a "one size fits all" symptom-based methodology to a more patient-centered, individualized approach to asthma treatment targeting the underlying disease process. A significant contributor to this shift to more personalized asthma therapy has been the increasing availability of numerous biologic therapies in recent years, providing the opportunity for more targeted treatments. When targeted biologics began to be developed for treatment of asthma, the hope was that distinct biomarkers would become available, allowing the clinician to determine which biologic therapy was best suited for which patients. Presence of certain biomarkers, like eosinophilia or antigen-specific IgE, is important features of specific asthma phenotypes. Currently available biomarkers can help with decision making about biologics, but are generally too broad and non-specific to clearly identify an asthma phenotype or the single biologic best suited to an asthmatic. Identification of further biomarkers is the subject of intense research. Yet, identifying a patient's asthma phenotype can help in predicting disease course, response to treatment, and biologic therapies to consider. In this review, major asthma phenotypes are reviewed, and the evidence for the utility of various biologics, both those currently on the market and those in the development process, in each of these phenotypes is explored.

Abstract
PURPOSE OF REVIEW There is an emerging body of research on targeted biologic therapies for the treatment of severe inflammatory nasal disorders, especially chronic rhinosinusitis with nasal polyposis (CRSwNP). This paper will evaluate the efficacy of biologic therapies for severe nasal inflammation by summarizing key preclinical trials of biologics for animal models of allergic rhinitis and the recent phase 2 and 3 clinical trials of biologic therapies for CRSwNP. RECENT FINDINGS Biologics that target the IL-4 receptor (dupilumab), IgE (omalizumab), and IL-5 (mepolizumab, reslizumab, and benralizumab) in patients with CRSwNP have shown improvement of various metrics including Sino-Nasal Outcome Test (SNOT-22) scores, Nasal Polyp Scores (NPS), Nasal Congestion Scores (NCS), and Lund-Mackay sinus opacification scores. The efficacy demonstrated through the dupilumab phase 3 trials (LIBERTY NP SINUS-24 and SINUS-52) led to approval of the first biologic for the treatment of CRSwNP. Phase 3 trials for omalizumab (POLYP 1 and 2) and mepolizumab (SYNAPSE study) and post hoc analyses of phase 3 asthma studies for reslizumab and benralizumab have also demonstrated positive results for the use of biologics for patients with CRSwNP. Future efficacy studies and risk/benefit and cost analyses of these biologics and other cytokine targets for allergic rhinitis with and without nasal polyposis need to be performed.

Abstract
Type 2 (T2) inflammation plays a key role in the pathogenesis of asthma. IL-4, IL-5, and IL-13, along with other inflammatory mediators, lead to increased cellular eosinophilic inflammation. It is likely that around half of all patients with asthma have evidence of T2-high inflammation. Sputum and blood eosinophils, exhaled nitric oxide, blood IgE levels, and airway gene expression markers are frequently used biomarkers of T2-high asthma. Individuals with T2-high asthma tend to have several features of increased asthma severity, including reduced lung function and increased rates of asthma exacerbations, and T2-high patients demonstrate distinct pathologic features including increased airway remodeling and alterations in airway mucus production. Several monoclonal antibodies are now available to treat individuals with T2-high asthma and these medications significantly reduce asthma exacerbation rates.

Abstract
Chronic rhinosinusitis (CRS) with polyps is associated with eosinophilic inflammation, in which the key mediator is interleukin - 5 (IL-5) and is often combined with asthma. RESEARCH OBJECTIVES To evaluate the therapeutic potential of reslizumab-humanized anti-IL-5 monoclonal antibody for the treatment of CRS with polyps in patients with severe asthma. PATIENTS AND METHODS We investigated the cases of 9 patients with severe asthma treated with intravenous reslizumab at a dose of 3 mg per 1 kg of weight with regularity once in 4 weeks. The presence of CRS with polyps was revealed in 7 of 9 patients, SCT scanning of the paranasal sinuses indicated changes in all the patients, 2 patients had symptoms of chronic non-allergic rhinitis (NARES).The treatment effectiveness control was carried out after 6 months from the beginning of the treatment by the dynamics of nasal symptoms (SNOT-22), endoscopic image of the nose, total polyp score (TPS), changes in the SCT of the paranasal sinuses on the Lund-Mackay scale, rhinocytogram, the content of eosinophilic cationic protein in the blood, the level of systemic eosinophilia. The effectiveness of asthma control was assessed by the reduction of the frequency of asthma exacerbations, the need for systemic corticosteroids, spirometry data and Asthma Control Test (ACT) results. Along with a marked improvement in asthma control, 8 out of 9 patients displayed clinical, endoscopic, radiological signs of weakening of nasal symptoms. More significant improvement in asthma control was achieved in patients having CRS with polyps. In the group of patients having CRS with polyps, it was possible to detect anamnestic presence of NARES symptoms in the early stages of the disease. This indicates that NARES can be a precursor to the development of eosinophilic, non-IgE-induced asthma and nasal polyps. CONCLUSION Treatment with reslizumab in patients with eosinophilic asthma and concomitant CRS with polyps and chronic non-allergic rhinitis (NARES) leads not only to improved control of asthma symptoms, but also to a significant regression of nasal symptoms.

Abstract
BACKGROUND This living systematic review is one of several Cochrane Reviews evaluating the medical management of patients with chronic rhinosinusitis. Chronic rhinosinusitis is common. It is characterised by inflammation of the nasal and sinus linings, nasal blockage, rhinorrhoea, facial pressure/pain and loss of sense of smell. It occurs with or without nasal polyps. 'Biologics' are medicinal products produced by a biological process. Monoclonal antibodies are one type, already evaluated in other inflammatory conditions (e.g. asthma and atopic dermatitis). OBJECTIVES To assess the effects of biologics for the treatment of chronic rhinosinusitis. SEARCH METHODS The Cochrane ENT Information Specialist searched the Cochrane ENT Register; CENTRAL (2020, Issue 9); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished studies. The date of the search was 28 September 2020. SELECTION CRITERIA Randomised controlled trials (RCTs) with at least three months follow-up comparing biologics (monoclonal antibodies) against placebo/no treatment in patients with chronic rhinosinusitis. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. Our primary outcomes were disease-specific health-related quality of life (HRQL), disease severity and serious adverse events (SAEs). The secondary outcomes were avoidance of surgery, extent of disease (measured by endoscopic or computerised tomography (CT) score), generic HRQL and adverse effects (nasopharyngitis, including sore throat). We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS We included 10 studies. Of 1262 adult participants, 1260 had severe chronic rhinosinusitis with nasal polyps; 43% to 100% of participants also had asthma. Three biologics, with different targets, were evaluated: dupilumab, mepolizumab and omalizumab. All of the studies were sponsored or supported by industry. For this update (2021) we have included two new studies, including 265 participants, which reported data relating to omalizumab. Anti-IL-4Rα mAb (dupilumab) versus placebo/no treatment (all receiving intranasal steroids) Three studies (784 participants) evaluated dupilumab. Disease-specific HRQL was measured with the SNOT-22 (a 22-item questionnaire, with a score range of 0 to 110; minimal clinically important difference (MCID) 8.9 points). At 24 weeks, dupilumab results in a large reduction (improvement) in the SNOT-22 score (mean difference (MD) -19.61, 95% confidence interval (CI) -22.54 to -16.69; 3 studies; 784 participants; high certainty). At between 16 and 52 weeks of follow-up, dupilumab probably results in a large reduction in disease severity, as measured by a 0- to 10-point visual analogue scale (VAS) (MD -3.00, 95% CI -3.47 to -2.53; 3 studies; 784 participants; moderate certainty). This is a global symptom score, including all aspects of chronic rhinosinusitis symptoms. At between 16 and 52 weeks of follow-up, dupilumab may result in a reduction in serious adverse events compared to placebo (5.9% versus 12.5%, risk ratio (RR) 0.47, 95% CI 0.29 to 0.76; 3 studies, 782 participants; low certainty). Anti-IL-5 mAb (mepolizumab) versus placebo/no treatment (all receiving intranasal steroids) Two studies (137 participants) evaluated mepolizumab. Disease-specific HRQL was measured with the SNOT-22. At 25 weeks, the SNOT-22 score may be reduced (improved) in participants receiving mepolizumab (MD -13.26 points, 95% CI -22.08 to -4.44; 1 study; 105 participants; low certainty; MCID 8.9). It is very uncertain whether there is a difference in disease severity at 25 weeks: on a 0- to 10-point VAS, disease severity was -2.03 lower in those receiving mepolizumab (95% CI -3.65 to -0.41; 1 study; 72 participants; very low certainty). It is very uncertain if there is a difference in the number of serious adverse events at between 25 and 40 weeks (1.4% versus 0%; RR 1.57, 95% CI 0.07 to 35.46; 2 studies; 135 participants, very low certainty). Anti-IgE mAb (omalizumab) versus placebo/no treatment (all receiving intranasal steroids) Five studies (329 participants) evaluated omalizumab. Disease-specific HRQL was measured with the SNOT-22. At 24 weeks omalizumab probably results in a large reduction in SNOT-22 score (MD -15.62, 95% CI -19.79 to -11.45; 2 studies; 265 participants; moderate certainty; MCID 8.9). We did not identify any evidence for overall disease severity. It is very uncertain whether omalizumab affects the number of serious adverse events, with follow-up between 20 and 26 weeks (0.8% versus 2.5%, RR 0.32, 95% CI 0.05 to 2.00; 5 studies; 329 participants; very low certainty). AUTHORS' CONCLUSIONS Almost all of the participants in the included studies had nasal polyps (99.8%) and all were using topical nasal steroids for their chronic rhinosinusitis symptoms. In these patients, dupilumab improves disease-specific HRQL compared to placebo. It probably also results in a reduction in disease severity, and may result in a reduction in the number of serious adverse events. Mepolizumab may improve disease-specific HRQL. It is very uncertain if there is a difference in disease severity or the number of serious adverse events. Omalizumab probably improves disease-specific HRQL compared to placebo. It is very uncertain if there is a difference in the number of serious adverse events. There was no evidence regarding the effect of omalizumab on disease severity (using global scores that address all symptoms of chronic rhinosinusitis).

Abstract
OBJECTIVE The large amount of evidence and the renewed interest in upper and lower airways involvement in infectious and inflammatory diseases has led Interasma (Global Asthma Association) to take a position on United Airways Diseases (UAD). METHODS Starting from an extensive literature review, Interasma executive committee discussed and approved this Manifesto developed by Interasma scientific network (INES) members. RESULTS The manifesto describes the evidence gathered to date and defines, states, advocates, and proposes issues on UAD (rhinitis, rhinosinusitis and nasal polyposis), and concomitant/comorbid lower airways disorders (asthma, chronic obstructive pulmonary disease, bronchiectasis, cystic fibrosis, obstructive sleep apnoea) with the aim of challenging assumptions, fostering commitment, and bringing about change. UAD refers to clinical pictures characterized by the coexistence of upper and lower airways involvement, driven by a common pathophysiological mechanism, leading to a greater burden on patient's health status and requiring an integrated diagnostic and therapeutic plan. The high prevalence of UAD must be taken into account. Upper and lower airways diseases influence disease control and patient's quality of life. CONCLUSIONS Patients with UAD need to have a timely and adequate diagnosis, treatment, and, when recommended, referral for management in a specialized center. Diagnostic testing including skin prick or serum specific IgE, lung function, fractional exhaled nitric oxide (FeNO), polysomnography, allergen-specific immunotherapies, biological therapies and home based continuous positive airway pressure (CPAP) whenever these are recommended, should be part of the management plan for UAD. Education of medical students, physicians, health professionals, patients and caregivers on the UAD is needed.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) represents a challenging disease entity with significant rates of recurrence following appropriate medical and surgical therapy. Recent approval of targeted biologics in CRSwNP compels deeper understanding of underlying disease pathophysiology. Both of the approved biologics for CRSwNP modulate the type 2 inflammatory pathway, and the majority of drugs in the clinical trials pathway are similarly targeted. However, there remain multiple other pathogenic mechanisms relevant to CRSwNP for which targeted therapeutics already exist in other inflammatory diseases that have not been studied directly. In this article we summarize pathogenic mechanisms of interest in CRSwNP and discuss the results of ongoing clinical studies of targeted therapeutics in CRSwNP and other related human inflammatory diseases.

Indirect Treatment Comparison of Biologics in Chronic Rhinosinusitis with Nasal Polyps. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:2461-2471.e5. [PMID: 33548517 DOI: 10.1016/j.jaip.2021.01.031] [Citation(s) in RCA: 49] [Impact Index Per Article: 16.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 12/09/2020] [Accepted: 01/22/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Among patients with chronic rhinosinusitis with nasal polyps (CRSwNP), randomized clinical trials (RCTs) of biologics, such as anti-interleukin-4/interleukin-13 (dupilumab) and anti-immunoglobulin E (omalizumab), have demonstrated efficacy compared with intranasal corticosteroids (INCS). However, no head-to-head RCTs exist between biologics. OBJECTIVE To perform an indirect treatment comparison (ITC) of the efficacy of biologics plus INCS versus placebo (INCS) as a common comparator. METHODS Embase, MEDLINE, and Cochrane were searched for RCTs of biologics in CRSwNP. Bucher ITCs were performed for outcomes at week 24: nasal polyp score (NPS) (range, 0-8), nasal congestion (NC) (range, 0-3), loss of smell (range, 0-3), University of Pennsylvania Smell Identification Test (range, 0-40), total symptom score (range, 0-12), 22-item sinonasal outcome test (range, 0-110), and responder analyses based on NPS or NC improvement of 1 point or greater. RESULTS Assessment of trial design, baseline characteristics, and outcome measures suggested that ITC was feasible with four phase 3 RCTs: dupilumab SINUS-24 and SINUS-52 (NCT02912468/NCT02898454) and omalizumab POLYP 1 and POLYP 2 (NCT03280550/NCT03280537). In the intent-to-treat population, dupilumab had significantly greater improvements from baseline to week 24 versus omalizumab across key outcomes: NPS (least squares mean difference [95% confidence interval], -1.04 [-1.63 to -0.44]), NC (-0.35 [-0.60 to -0.11]), loss of smell (-0.66 [-0.90 to -0.42]), University of Pennsylvania Smell Identification Test (6.70 [4.67-8.73]), and total symptom score (-1.18 [-1.95 to -0.41]). Improvement in the 22-item sinonasal outcome test was greater in dupilumab versus omalizumab but was not statistically significant. Dupilumab patients were significantly more likely to achieve ≥1-point improvement in NPS (odds ratio [95% CI] = 3.58 [1.82-7.04]) and NC (2.13 [1.12-4.04]) versus omalizumab. CONCLUSIONS Although ITCs have limitations, these results demonstrated that dupilumab had consistently greater improvements in key CRSwNP outcomes versus omalizumab at week 24.

Efficacy of Tezepelumab in Patients with Severe, Uncontrolled Asthma with and without Nasal Polyposis: A Post Hoc Analysis of the Phase 2b PATHWAY Study. J Asthma Allergy 2021; 14:91-99. [PMID: 33568920 PMCID: PMC7868291 DOI: 10.2147/jaa.s288260] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 01/06/2021] [Indexed: 12/17/2022] Open
Abstract
Background Tezepelumab is a human monoclonal antibody that blocks thymic stromal lymphopoietin, an epithelial cytokine implicated in asthma pathogenesis, from binding to its heterodimeric receptor. In the phase 2b PATHWAY study, tezepelumab significantly reduced annualized asthma exacerbation rates (AAERs) versus placebo, irrespective of baseline disease characteristics, and improved lung function and symptom control, in adults with severe, uncontrolled asthma. This post hoc analysis assessed the efficacy of tezepelumab in adults with severe, uncontrolled asthma with and without nasal polyposis (NP). Methods In this post hoc analysis of the PATHWAY study (NCT02054130), participants (N=550) were randomized 1:1:1:1 to receive subcutaneous tezepelumab 70 mg every 4 weeks (Q4W), 210 mg Q4W or 280 mg every 2 weeks (Q2W), or placebo Q2W, for 52 weeks. The AAER over 52 weeks and the change from baseline to week 52 in blood eosinophil count, fractional exhaled nitric oxide (FeNO) levels and serum levels of interleukin (IL)-5 and IL-13 with tezepelumab 210 mg (the phase 3 dose) and placebo were analyzed in patients grouped by self-reported presence (NP+) or absence (NP-) of NP at screening. Results At baseline, NP+ patients had higher blood eosinophil counts, higher FeNO levels and higher serum IL-5 and IL-13 levels than NP- patients. Tezepelumab 210 mg reduced the AAER versus placebo to a similar extent in both NP+ and NP- patients (NP+, 75% [95% confidence interval (CI): 15, 93], n=23; NP-, 73% [95% CI: 47, 86], n=112). Patients treated with tezepelumab 210 mg demonstrated greater reductions in blood eosinophil count and levels of FeNO, IL-5 and IL-13 than placebo-treated patients, irrespective of NP status. Discussion Tezepelumab reduced exacerbations and reduced type 2 inflammatory biomarkers in patients with and those without NP, supporting its efficacy in a broad population of patients with severe asthma.

Abstract
PURPOSE OF REVIEW The aim of this study was to highlight the phenotypes and endotypes of asthma as a tool for selection of the Food and Drug Administration approved biologic therapies. RECENT FINDINGS An evolving concept of asthma has led to the identification of distinct phenotypes and endotypes in this disease. Asthma endotypes are defined as the biological mechanism and are often categorized as T2-high and T2-low based on the influence of T helper type 2 (T2) cells and type 2 cytokines, including interleukin (IL)-4, IL-5, IL-9 and IL-13. Biomarkers such as peripheral blood absolute eosinophil count, total IgE, specific IgE and fractional exhaled nitric oxide may be used as indicators of asthma endotypes and help predict response to biologic therapies. There are currently five biologic therapies approved as a treatment option for T2-high asthma: omalizumab, benralizumab, mepolizumab, reslizumab and dupilumab. SUMMARY Here, we explore the current understandings of asthma endotypes and review their associated phenotypes. We provide practical and evidence-based guidance for clinicians considering a biologic for asthma add-on maintenance therapy.

Abstract
BACKGROUND Comorbidities are common in asthma and may complicate treatment response. OBJECTIVE To examine response to omalizumab in patients with moderate-to-severe allergic asthma by asthma-related and allergic comorbidities. METHODS Patients aged 12 years or more from placebo-controlled 008/009 (n = 1071), EXTRA (n = 848), and INNOVATE (n = 419), and single-armed PROSPERO (n = 801) omalizumab studies were included. Poisson regression/analysis of covariance models were used to estimate adjusted exacerbation rates and forced expiratory volume in 1 second (FEV1) change from baseline after omalizumab initiation for subgroups by number of comorbidities (0, 1 [008/009]; 0, 1, ≥2 [EXTRA and INNOVATE]; 0, 1, 2, ≥3 [PROSPERO]). Self-reported comorbidities included allergic rhinoconjunctivitis, chronic rhinosinusitis, recurrent acute sinusitis, nasal polyps, atopic and contact dermatitis, urticaria, food allergy, anaphylaxis, other allergies, gastroesophageal reflux disease, eosinophilic esophagitis, and eosinophilic granulomatosis with polyangiitis. RESULTS In the EXTRA and INNOVATE studies, no consistent pattern was observed for placebo-corrected relative rate reduction in normalized asthma exacerbations among omalizumab-treated comorbidity subgroups. In PROSPERO, on-study exacerbation rates in the comorbidity subgroups were similar (0, 0.68; 1, 0.70; 2, 0.77; ≥3, 0.80). FEV1 improvements were observed throughout the study for omalizumab vs placebo for all comorbidity subgroups. There were no consistent differences in FEV1 improvements among comorbidity subgroups in 008/009, EXTRA, or INNOVATE. Similarly, no among-group differences were observed for FEV1 change from baseline at month 12 in PROSPERO (0, 0.05 L; 1, 0.08 L; 2, 0.00 L; ≥3, 0.04 L). The 95% confidence intervals overlapped substantially in all instances. CONCLUSION In these analyses of placebo-controlled/single-armed studies, on-study exacerbation rates and FEV1 improvements with omalizumab treatment were similar irrespective of comorbidity burden. TRIAL REGISTRATION ClinicalTrials.gov identifiers are as follows: EXTRA, NCT00314574 (https://clinicaltrials.gov/ct2/show/NCT00314574); INNOVATE, NCT00046748 (https://clinicaltrials.gov/ct2/show/NCT00046748); and PROSPERO, NCT01922037 (https://clinicaltrials.gov/ct2/show/NCT01922037).

Abstract
BACKGROUND Aspirin-exacerbated respiratory disease (AERD) affects 7% of asthmatics. Usual therapies are inadequate for asthma and/or nasal polyposis, leading to decreased quality of life. OBJECTIVE Our objective was to evaluate the efficacy of dupilumab in AERD patients with uncontrolled, chronic rhinosinusitis with nasal polyposis (CRSwNP). METHODS Patients 18 years and older with a physician diagnosis of AERD and sino-nasal outcome test 22 (SNOT 22) score ≥19 despite standard medical therapy were eligible for the study. Patients received one month of placebo dosing, followed by 6 months of dupilumab. Patients were blinded to the order of therapy. Wilcoxon-paired rank sum test was used to compare study outcomes at baseline and the completion of the study. RESULTS Ten patients completed the study. The median baseline SNOT 22 score improved from 46 [IQR: 34 to 64.8] to 9.5 [IQR: 2.5 to 19] after 6 months of therapy (p = 0.0050). The median baseline Lund MacKay score improved from 21.5 [IQR: 17 to 23.3] to 4 [IQR: 1.2 to 6] after 6 months of therapy (p = 0.0050). There was also improvement in the following secondary outcomes: asthma control test (ACT), mini asthma quality of life questionnaire (AQLQ), and University of Pennsylvania Smell Identification test (UPSIT). Exhaled nitric oxide (FeNO), total serum IgE, 24-hour urinary leukotriene E4, and serum thymus and activation regulated cytokine (TARC) also decreased. There were no significant study-related adverse events. CONCLUSION Dupilumab was highly effective as add-on therapy for CRSwNP in AERD, improving patient-reported outcomes, sinus opacification, and markers of T2 inflammation.

Abstract
Severe refractory asthma (SRA) still has a high economic and social impact, including a reduction in quality of life (QoL), productivity, a greater risk of exacerbations and emergency department (ED) visits. Another major issue is the need of oral corticosteroids (OCS), often due to a poor response to standard therapies or the lack of indication for currently available biological drugs. A thorough understanding of the immunological pathways and eosinophilopoietic processes allows a correct application of the new pharmacological strategies and leads to better clinical responses. For these unmet needs, several monoclonal antibody (mAb) drugs have been introduced over the past few years. These are mainly available for allergic and especially eosinophilic uncontrolled refractory asthma. As the number of therapeutic options increases, the choice of biological drugs can be made only after careful considerations of the particular asthma endotype, patients’ comorbidities and clinical data. The selection of the correct therapeutic option can therefore be guided after a careful evaluation of the particular endotype and phenotype, from the combined evaluation of inflammatory biomarkers, clinical picture and comorbidities. The careful evaluation of all these parameters can therefore help the physician in the optimal management of these complex patients, for whom it is often possible to achieve exceptional results by managing the available options in the best possible way. The aim of this review is to define the positioning of the biological drugs currently available for type 2 asthma, with a special focus on options for eosinophilic asthma in the context of the most recent knowledge of immunological pathways.

Abstract
Nonsteroidal antiinflammatory drug (NSAID)-exacerbated respiratory disease (NERD) is characterized by moderate-to-severe asthma and a higher prevalence of chronic rhinosinusitis/nasal polyps, but is a highly heterogeneous disorder with various clinical manifestations. Two major pathogenic mechanisms are: (1) overproduction of cysteinyl leukotrienes with dysregulation of arachidonic acid metabolism and (2) increased type 2 eosinophilic inflammation affected by genetic mechanisms. Aspirin challenge is the gold standard to diagnose NERD, whereas reliable in vitro biomarkers have yet not been identified. Therapeutic approaches have been done on the basis of disease severity with the avoidance of culprit and cross-reacting NSAIDs, and when indicated, aspirin desensitization is an effective treatment option. Biologic approaches targeting Type 2 cytokines are emerging as potential therapeutic options. Here, we summarize the up-to-date evidence of pathophysiologic mechanisms and diagnosis/management approaches to the patients with NERD with its phenotypic classification.

Abstract
PURPOSE OF REVIEW Nonsteroidal anti-inflammatory drug (NSAID) is one of the most frequently prescribed medications in the medical field, and hypersensitivity to NSAID is a common adverse drug reaction encountered. However, NSAID hypersensitivity presents a variety of symptoms caused by diverse pharmacological and immunological mechanisms. RECENT FINDINGS Owing to the heterogeneity of the disease, a new concept for the classification of NSAID hypersensitivity has recently been proposed to diagnose and manage NSAID hypersensitivity for personalized treatment. Acute and delayed reactions were distinguished in this classification, and identification of symptoms and speculation of putative mechanisms help physicians make the right diagnosis. NSAID-exacerbated respiratory disease is a noticeable phenotype of NSAID hypersensitivity that involves upper airway comorbidities (chronic rhinosinusitis with nasal polyps) as well as asthmatic features. The cutaneous phenotypes of NSAID hypersensitivity occur, and cross-reactivity with other types of NSAID should be considered in establishing a proper diagnosis. Hypersensitivity to a single NSAID can present urticaria/angioedema and anaphylaxis, in which an IgE-mediated immune response is suggested to be a prime mechanism. Management of NSAID hypersensitivity reactions includes avoidance, pharmacological treatment following standard guidelines, and aspirin desensitization. SUMMARY The classification, diagnosis, and management of NSAID hypersensitivity should be individually reached by identifying its phenotype.

[PMID: 32629016 DOI: 10.1016/j.anai.2020.06.041] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 06/03/2020] [Accepted: 06/24/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Asthma is a heterogeneous disease with emerging phenotypes and endotypes. At present, 5 distinct biologics are Food and Drug Administration-approved as an add-on therapy for difficult-to-control type 2-high asthma. Because allergy specialists manage a spectrum of diseases for which biologics may be appropriate, it is important to understand their prescribing patterns. OBJECTIVE To elucidate the allergist's use of biologics in the treatment of asthma, including barriers, preferences, indications for prescribing, measures to determine effectiveness, and cost-effectiveness. METHODS A survey was performed among allergists using a semistructured 10-item self-administered web-based questionnaire and the responses were analyzed using one-way frequencies and multiple logistic regression. RESULTS The response rate was approximately 9%. Omalizumab was the most prescribed biologic for asthma (98%), and "uncontrolled asthma despite adherence to controller medication" was the most common reason. The common selection criteria among the biologics included elevated peripheral eosinophil count, asthma with nasal polyps, and asthma type (type 1; type 2; nonallergic). A decreased exacerbation frequency was the best standard to determine the efficacy among biologics. Benralizumab was considered the most cost-effective. CONCLUSION This study represents one of the largest surveys among allergy specialists regarding the real-world use of asthma biologics. It seems that there has been reasonably good dissemination and application of current guidelines among allergists based on prescribing patterns. However, their responses reflect the need for the continued modification of asthma guidelines that incorporate novel biologics and other pathway-specific agents into step therapy. As clinical phenotypes and predictive biomarkers develop, allergy specialists will be better prepared to practice precision medicine that optimizes the use of asthma biologics.

Successful treatment of eosinophilic chronic rhinosinusitis and eosinophilic otitis media using the anti-IL-5 receptor monoclonal antibody benralizumab: A case report. Respir Med Case Rep 2020; 30:101135. [PMID: 32612919 PMCID: PMC7322358 DOI: 10.1016/j.rmcr.2020.101135] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 06/16/2020] [Accepted: 06/16/2020] [Indexed: 01/21/2023] Open
Abstract
Eosinophilic chronic rhinosinusitis (ECRS) is characterized by the presence of nasal polyps, dominant ethmoid shadows in computed tomography (CT) scans, and elevated levels of eosinophil infiltration into the nasal polyps and peripheral blood. ECRS is often accompanied by severe asthma. The recent development of monoclonal antibody-based biologics, including benralizumab, has offered new therapeutic approaches for the treatment of asthma and allergic diseases. Asthma and ECRS are closely related; hence, benralizumab could provide clinical benefit in ECRS patients with severe asthma. Herein, we report a case of a 47-year-old female patient with severe asthma that presented with nasal obstruction and hearing impairment. Nasal endoscopic and otoscopic examinations indicated the presence of bilateral nasal polyps in the middle nasal meatus, as well as a bilateral effusion in the tympanic cavity. Sinus and temporal CT images showed dominant ethmoid sinus and tympanic cavity shadows. Biopsy of nasal polyps revealed high numbers of eosinophils, which led to the diagnosis of ECRS; eosinophilic otitis media (EOM) with hypereosinophilia was also suspected. Treatment with benralizumab reduced the number of peripheral blood eosinophils and improved asthma symptoms. Prolonged benralizumab administration also resulted in a remarkable size reduction in bilateral middle nasal polyps and aeration of the tympanic cavity. In conclusion, benralizumab treatment improved the symptoms of severe asthma, ECRS, and EOM. Eosinophil depletion could be an important mechanism by which benralizumab improves ECRS and EOM. The use of benralizumab for the treatment of ECRS and EOM patients with severe asthma merits further investigation in large-cohort studies.

Should we consider paranasal and chest computed tomography in severe asthma patients? Respir Med 2020; 169:106013. [PMID: 32442110 DOI: 10.1016/j.rmed.2020.106013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 05/04/2020] [Accepted: 05/05/2020] [Indexed: 01/02/2023]
Abstract
BACKGROUND It is essential to recognize and treat findings that can simulate or worsen symptoms to improve asthma control and thereby to reduce costs. Guidelines highlight a paranasal (PS) and chest computed tomography (CT) scan as a tool for disease evaluation and, although they suggest its indication in patients whom presentation is atypical, there are not well-defined criteria. OBJECTIVES To describe the most common findings in the PS and chest CT in severe asthma patients and to analyse the characteristics of asthmatics with the finding of nasal polyps or bronchiectasis. METHODS We retrospectively reviewed the medical records of 161 adults with confirmed severe asthma who had undergone to PS and/or chest CT. Clinical data from their electronic health record and the findings from a PS and/or chest CT within the last five years were collected. RESULTS In the PS CT, 70.5% of patients presented mucous thickening and 46.7% presented nasal polyps. Both findings were associated with male gender and level of blood eosinophils. In chest CT, 28% of individuals showed atelectasis, 16.5% air trapping, 17.7% affectation of the small airway, 11.6% pulmonary infiltrates and 10.4% emphysema. Bronchiectasis were identified in 60.4% of subjects, who were older and had poorer lung function. CONCLUSION Paranasal and thoracic computed tomography are important tools in the treatment of severe asthma because they allow us to detect highly prevalent findings in this disease that can lead to poorer control of it.

How to compare the efficacy of biologic agents in asthma. Ann Allergy Asthma Immunol 2020; 125:137-149.

Abstract
OBJECTIVE The use of biologics in severe asthma has made substantial strides in disease management and fostered a personalized medicine approach; however, how, when, and which biologic to choose are unresolved issues, which form the focus of this review. DATA SOURCES The data sources were published literature, including current guidelines, available through PubMed searches and online resources. STUDY SELECTIONS Studies and randomized controlled trials pertaining to the use of biologics in various phenotypes and/or endotypes of asthma and comparative analyses between biologics in asthma were included. RESULTS Inflammatory constructs in asthma are complex and translate differentially into clinical practice for both disease severity and treatment responsiveness. The utilization of biologics, which target selected components of inflammation, has begun to dramatically improve the course of management for many patients with severe asthma. A retuning of our approach into selecting appropriate patient cohorts or phenotypes for studies and selection of clinically relevant outcomes, which are reflected by existing and novel emerging biomarkers, is enabling a paradigm shift in asthma management. Comparing the efficacy of the available biologics for asthma is challenging as no direct head-to-head studies are available, and indirect comparisons to this query provide varying results. CONCLUSION Significant progress has been achieved in the management of severe asthma with treatment of target-specific biologics. Sophisticated algorithms and trial designs, using a combination of available biomarker profiles and clinical characteristics to stratify patient populations into more precise subphenotypes and endotypes to guide our choice of a biologic or therapy, are critically needed but currently not formulated.

Abstract
Aspirin-exacerbated respiratory disease (AERD) classically presents with severe asthma, nasal polyposis, and respiratory exacerbations in response to cyclooxygenase (COX)-1 inhibition. Recent advances in our understanding of AERD have revealed multiple facets of immune dysregulation, including diminished prostaglandin E2 (PGE2) function and elevated levels of both cysteinyl leukotrienes (CysLTs) and innate cytokines such as interleukin 33 (IL-33). Inflammatory mediators in AERD heighten the recruitment and activation of innate lymphoid cells type 2 (ILC2), mast cells, eosinophils, and platelet-adherent leukocytes. This contributes to a cyclical pattern of type 2 inflammation. Here, we highlight current understanding of the immunopathogenesis of AERD.

Abstract
BACKGROUND This living systematic review is one of several Cochrane Reviews evaluating the medical management of patients with chronic rhinosinusitis. Chronic rhinosinusitis is common. It is characterised by inflammation of the nasal and sinus linings, nasal blockage, rhinorrhoea, facial pressure/pain and loss of sense of smell. It occurs with or without nasal polyps. 'Biologics' are medicinal products produced by a biological process. Monoclonal antibodies are one type, already evaluated in related inflammatory conditions (e.g. asthma and atopic dermatitis). OBJECTIVES To assess the effects of biologics for the treatment of chronic rhinosinusitis. SEARCH METHODS The Cochrane ENT Information Specialist searched the Cochrane ENT Register; CENTRAL (2019, Issue 9); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 16 September 2019. SELECTION CRITERIA Randomised controlled trials (RCTs) with at least three months follow-up comparing biologics (currently, monoclonal antibodies) against placebo/no treatment in patients with chronic rhinosinusitis. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. Our primary outcomes were disease-specific health-related quality of life (HRQL), disease severity and serious adverse events (SAEs). The secondary outcomes were avoidance of surgery, extent of disease (measured by endoscopic or computerised tomography (CT) score), generic HRQL and adverse events (nasopharyngitis, including sore throat). We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS We included eight RCTs. Of 986 adult participants, 984 had severe chronic rhinosinusitis with nasal polyps; 43% to 100% of participants also had asthma. Three biologics, with different targets, were evaluated: dupilumab, mepolizumab and omalizumab. All the studies were sponsored or supported by industry. Anti-IL-4Rα mAb (dupilumab) versusplacebo/no treatment (all receiving intranasal steroids) Three studies (784 participants) evaluated dupilumab. Disease-specific HRQL was measured with the SNOT-22 (score 0 to 110; minimal clinically important difference (MCID) 8.9 points). At 24 weeks, the SNOT-22 score was 19.61 points lower (better) in participants receiving dupilumab (mean difference (MD) -19.61, 95% confidence interval (CI) -22.54 to -16.69; 3 studies; 784 participants; high certainty). Symptom severity measured on a 0- to 10-point visual analogue scale (VAS) was 3.00 lower in those receiving dupilumab (95% CI -3.47 to -2.53; 3 studies; 784 participants; moderate certainty). The risk of serious adverse events may be lower in the dupilumab group (risk ratio (RR) 0.45, 95% CI 0.28 to 0.75; 3 studies; 782 participants; low certainty). The number of participants requiring nasal polyp surgery (actual or planned) during the treatment period is probably lower in those receiving dupilumab (RR 0.17, 95% CI 0.05 to 0.52; 2 studies; 725 participants; moderate certainty). Change in the extent of disease using the Lund Mackay computerised tomography (CT) score (0 to 24, higher = worse) was -7.00 (95% CI -9.61 to -4.39; 3 studies; 784 participants; high certainty), a large effect favouring the dupilumab group. The EQ-5D visual analogue scale (0 to 100, higher = better; MCID 8 points) was used to measure change in generic quality of life. The mean difference favouring dupilumab was 8.59 (95% CI 5.31 to 11.86; 2 studies; 706 participants; moderate certainty). There may be little or no difference in the risk of nasopharyngitis (RR 0.95, 95% CI 0.72 to 1.25; 3 studies; 783 participants; low certainty). Anti-IL-5 mAb (mepolizumab) versusplacebo/no treatment (all receiving intranasal steroids) Two studies (137 participants) evaluated mepolizumab. Disease-specific HRQL measured with the SNOT-22 at 25 weeks was 13.26 points lower (better) in participants receiving mepolizumab (95% CI -22.08 to -4.44; 1 study; 105 participants; low certainty; MCID 8.9). It is very uncertain whether there is a difference in s ymptom severity: on a 0- to 10-point VAS symptom severity was -2.03 lower in those receiving mepolizumab (95% CI -3.65 to -0.41; 1 study; 72 participants; very low certainty). It is very uncertain if there is difference in the risk of serious adverse events (RR 1.57, 95% CI 0.07 to 35.46; 2 studies; 135 participants, very low certainty). It is very uncertain whether or not the overall risk that patients still need surgery at trial end is lower in the mepolizumab group (RR 0.78, 95% CI 0.64 to 0.94; 2 studies; 135 participants; very low certainty). It is very uncertain whether mepolizumab reduces the extent of disease as measured by endoscopic nasal polyps score (scale range 0 to 8). The mean difference was 1.23 points lower in the mepolizumab group (MD -1.23, 95% -1.79 to -0.68; 2 studies; 137 participants; very low certainty). The difference in generic quality of life (EQ-5D) was 5.68 (95% CI -1.18 to 12.54; 1 study; 105 participants; low certainty), favouring the mepolizumab group. This difference is smaller than the MCID of 8 points. There may be little or no difference in the risk of nasopharyngitis (RR 0.73, 95% 0.36 to 1.47; 2 studies; 135 participants; low certainty). Anti-IgE mAb (omalizumab) versus placebo/no treatment (all receiving intranasal steroids) Three very small studies (65 participants) evaluated omalizumab. We are very uncertain about the effect of omalizumab on disease-specific HRQL, severe adverse events, extent of disease (CT scan scores), generic HRQL and adverse effects. AUTHORS' CONCLUSIONS In adults with severe chronic rhinosinusitis and nasal polyps, using regular topical nasal steroids, dupilumab improves disease-specific HRQL compared to placebo, and reduces the extent of the disease as measured on a CT scan. It probably also improves symptoms and generic HRQL and there is no evidence of an increased risk of serious adverse events. It may reduce the need for further surgery. There may be little or no difference in the risk of nasopharyngitis. In similar patients, mepolizumab may improve both disease-specific and generic HRQL. It is uncertain whether it reduces the need for surgery or improves nasal polyp scores. There may be little or no difference in the risk of nasopharyngitis. It is uncertain if there is a difference in symptom severity and the risk of serious adverse events. We are uncertain about the effects of omalizumab.
