Abstract
INTRODUCTION Despite adherence to inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) therapy, many patients with asthma experience moderate exacerbations. Data on the impact of moderate exacerbations on the healthcare system are limited. This study assessed the frequency and economic burden of moderate exacerbations in patients receiving ICS/LABA. METHODS Retrospective, longitudinal study analyzed data from Optum's de-identified Clinformatics® Data Mart Database recorded between October 1, 2015, and December 31, 2019. Eligibility criteria included patients ≥18 years of age with ≥1 ICS/LABA claim and ≥1 medical claim for asthma in the 12 months pre-index (first ICS/LABA claim). Primary objectives included describing moderate exacerbation frequency, and associated healthcare resource utilization (HRU) and costs. A secondary objective was assessing the relationship between moderate exacerbations and subsequent risk of severe exacerbations. Patients were stratified by moderate exacerbation frequency in the 12 months post index. Moderate exacerbations were identified using a newly developed algorithm. RESULTS In the first 12 months post index 61.6% of patients experienced ≥1 moderate exacerbation. Mean number of asthma-related visits was 4.1 per person/year and median total asthma-related costs was $3544. HRU and costs increased with increasing exacerbation frequency. Outpatient and inpatient visits accounted for a similar proportion of these costs. Moderate exacerbations were associated with an increased rate and risk of future severe exacerbations (incidence rate ratio, 1.56; hazard ratio, 1.51 [both p < 0.001]). CONCLUSIONS This study highlighted that a high proportion of patients continue to experience moderate exacerbations despite ICS/LABA therapy and subsequently experience increased economic burden and risk of future severe exacerbations.

Abstract
Asthma is a common chronic disease affecting the airways in the lungs. The receptors of allergic cytokines, including interleukin (IL)-4, IL-5, and IL-13, trigger the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway, which involves the pathogenesis of asthma. GDC-0214 is a JAK inhibitor that was developed as a potent and selective target for the treatment of asthma, specifically targeting the lungs. While inhaled GDC-0214 is a promising novel treatment option against asthma, improvement is still needed to achieve increased potency of the powder formulation and a reduced number of capsules containing powder to be inhaled. In this study, high-potency amorphous powder formulations containing GDC-0214 nanoaggregates for dry powder inhalation were developed using particle engineering technology, thin film freezing (TFF). A high dose per capsule was successfully achieved by enhancing the solubility of GDC-0214 and powder conditioning. Lactose and/or leucine as excipients exhibited optimum stability and aerosolization of GDC-0214 nanoaggregates, and aerosolization of the dose was independent of air flow through the device between 2 and 6 kPa pressure drops. In the rat PK study, formulation F20, which contains 80% GDC-0214 and 20% lactose, resulted in the highest AUC0-24h in the lungs with the lowest AUC0-24h in the plasma that corresponds to a 4.8-fold higher ratio of the lung-to-plasma exposures compared to micronized crystalline GDC-0214 powder administered by dry powder inhalation. Therefore, GDC-0214 nanoaggregates produced by TFF provided an improved dry powder for inhalation that can lead to enhanced therapeutic efficacy with a lower risk of systemic toxicity.

Abstract
BACKGROUND The management of mild asthma has lacked an over-the-counter (OTC) option aside from inhaled epinephrine, which is available in the United States. However, inhaled epinephrine use without an inhaled corticosteroid may increase the risk of asthma death. OBJECTIVE To compare the cost-effectiveness of OTC as-needed budesonide-formoterol as a plausible alternative to inhaled epinephrine. METHODS We developed a probabilistic Markov model to compare OTC as-needed budesonide-formoterol inhaler use vs inhaled epinephrine use in adults with mild asthma from a US societal perspective over a lifetime horizon, with a 3% annual discount rate (2022 US dollars). Inputs were derived from the SYmbicort Given as-needed in Mild Asthma (SYGMA) trials, published literature, and commercial costs. Outcomes were quality-adjusted life-years (QALY), costs, incremental net monetary benefit (INMB), severe asthma exacerbations, well-controlled asthma days, and asthma-related deaths. Microsimulation was used to evaluate underinsured Americans living with mild asthma (n = 5,250,000). RESULTS Inhaled epinephrine was dominated (with lower QALYs gains at a higher cost) by both as-needed budesonide-formoterol (INMB, $15,541 at a willingness-to-pay of $100,000 per QALY) and the no-OTC inhaler option (INMB, $1023). Adults using as-needed budesonide-formoterol had 145 more well-controlled asthma days, 2.79 fewer severe exacerbations, and an absolute risk reduction of 0.23% for asthma-related death compared with inhaled epinephrine over a patient lifetime. As-needed budesonide-formoterol remained dominant in all sensitivity and scenario analyses, with a 100% probability of being cost-effective compared with inhaled epinephrine in probabilistic sensitivity analysis. CONCLUSION If made available, OTC as-needed budesonide-formoterol for treating mild asthma in underinsured adults without HCP management improves asthma outcomes, prevents fatalities, and is cost-saving.

Abstract
BACKGROUND Bronchial thermoplasty (BT) is an approved procedure to manage uncontrolled severe persistent asthma. Many insurance providers are reluctant to pay for BT without proven benefit among their specific patient panel. OBJECTIVE Determine if BT is effective in a panel patient panel with uncontrolled severe persistent asthma. STUDY DESIGN AND METHODS This was an unblinded prospective study of adult subjects with uncontrolled severe persistent asthma who underwent BT. Outcomes were assessed at baseline and then 3-, 6-, 12-, 18- and 24-months post-BT. The primary metric was an improved Asthma Quality of Life Questionnaire (AQLQ) score. Other metrics included improved Asthma Control Test (ACT), peak expiratory flow rates (PEFR), spirometry, fractional excretion of nitric oxide (FeNO), number of unscheduled medical visits, and lost days of work/activity. Respiratory adverse events were assessed during the BT treatment period and at each post-BT visit. RESULTS Twenty-nine subjects completed the study; the median interquartile range (IQR) age was 47 (42-61), and the majority were female (69%), white (93%), and non-Hispanic (90%). After BT, mean (±std) AQLQ scores improved by 1.6(±1.1) at 3 months (p < 0.0001), 1.6(±1.2) at 6 months (p < 0.0001), 1.4(±1.0) at 12 months (p < 0.0001), 1.8(±1.1) at 18 months (p < 0.0001), and 1.6 (±1.5) at 24 months (p < 0.0001). There were significant improvements in ACT, PEFR, unscheduled medical visits and lost days of work and activity. Spirometry and FeNO metrics were unchanged. The average cost for subjects completing all 3 BT procedures was approximately $15,000. CONCLUSION BT is an effective adjunctive therapeutic modality in subjects with uncontrolled severe persistent asthma.

Abstract
Purpose Real-world asthma control data among patients initiating fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) are limited. This study assessed rescue medication use and asthma-related exacerbations in patients with asthma before and after initiating single-inhaler FF/UMEC/VI using administrative claims data. Patients and Methods This retrospective, pre-post cohort study analyzed data from the IQVIA PharMetrics Plus database (September 18, 2016‒March 31, 2020). Patients aged ≥18 years that had ≥1 dispensing of single-inhaler FF/UMEC/VI 100/62.5/25 mcg (first dispensing = index date), ≥12 months of continuous health insurance enrollment prior to (pre-treatment) and following (post-treatment) FF/UMEC/VI initiation and ≥1 diagnosis of asthma during the pre-treatment period or on the index date were included. The primary endpoint was the number of oral corticosteroid (OCS) dispensings per patient per year during pre- and post-treatment periods. Secondary endpoints included asthma-related exacerbation rates and short-acting β2-agonist (SABA) use. Comparisons between pre- and post-treatment periods were made using risk and rate ratios. Results Overall, 890 patients with asthma initiating treatment with FF/UMEC/VI were included. The most recently dispensed controller medications prior to FF/UMEC/VI initiation were inhaled corticosteroids/long-acting β2-agonists (33.5%) and leukotriene modifiers (33.0%). Patients had a 29% reduction in the number of OCS dispensings (rate ratio [95% confidence interval (CI)]: 0.71 [0.65, 0.77], P < 0.001) during post-treatment versus pre-treatment, with a 23% reduction in the proportion of patients with ≥1 OCS dispensing post-treatment (risk ratio [95% CI]: 0.77 [0.73, 0.82], P < 0.001). Significant reductions in rates (rate ratio [95% CI]) of asthma-related exacerbations (0.59 [0.52, 0.67], P < 0.001) and SABA use (0.80 [0.74, 0.86], P < 0.001) were also observed. Conclusion In this real-world study, patients with asthma had significantly lower OCS use, asthma-related exacerbations, and SABA use following treatment initiation with FF/UMEC/VI compared with their pre-treatment period. These results suggest better asthma control following initiation of FF/UMEC/VI in a routine clinical practice setting.

Abstract
Purpose Asthma is a common, chronic respiratory disorder associated with substantial societal and economic burden globally, despite the availability of different treatment modalities. GSK has developed a once-daily single-inhaler triple therapy (SITT), comprised of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI); a combination of inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting β2-agonist for patients with uncontrolled asthma. A budget impact analysis was conducted to determine the financial impact of introducing FF/UMEC/VI SITT from the perspective of the Dubai Academic Healthcare Corporation (DAHC). Methods A budget impact model was constructed using an epidemiology-based approach and used to estimate the expected 5-year budget impact of including FF/UMEC/VI for the treatment of eligible patients within the DAHC in the United Arab Emirates (UAE). The model included both pharmacy and efficacy-related costs. The perspective of the DAHC healthcare payer was adopted, thus only direct payer costs were included in the analysis. A one-way sensitivity analysis was conducted to test the robustness of the model structure, assumptions, and input parameters. Results The total budget impact was estimated to save 1 million United States Dollars (USD) over 5 years, with budget impacts of 0.08 million USD in Year 1; 0.14 million USD in Year 2; 0.22 million USD in Year 3; 0.28 million USD in Year 4; and 0.33 million USD in Year 5. The overall budget impact per patient was estimated to save 12.2 USD over 5 years. In one-way sensitivity analyses, the budget impact was most sensitive to changes in the market uptake of FF/UMEC/VI. Conclusion Healthcare payers may consider FF/UMEC/VI in the management of uncontrolled asthma which would save costs and reduce healthcare resource use in the UAE.

Abstract
This observational claims-linked survey study assessed the prevalence of and risk factors for suboptimal asthma control and healthcare utilization in adults with asthma receiving fixed-dose combination (FDC) inhaled corticosteroid/long-acting β2-agonist (ICS/LABA). Commercially insured adults from the Optum Research Database were invited to complete the Asthma Control Test (ACT) and Asthma Control Questionnaire-6 (ACQ-6). Among participants (N = 428), 36.4% (ACT-assessed) and 55.6% (ACQ-6-assessed) had inadequately controlled asthma. Asthma-related quality of life was worse and asthma-related healthcare resource utilization was higher in poorly controlled asthma. Factors associated with ACT-defined suboptimal asthma control in multivariate analysis included: frequent short-acting β2-agonist (SABA) use, asthma-related outpatient visits, lower treatment adherence, and lower education levels. During follow-up, factors associated with asthma exacerbations and/or high SABA use included: inadequately controlled asthma (ACT-assessed), body mass index ≥30 kg/m2, and high-dose ICS/LABA. Approximately 35-55% of adults with asthma were inadequately controlled despite FDC ICS/LABA; poor control was associated with worse disease outcomes.

Abstract
BACKGROUND During the transition from paediatric to adult healthcare there is a gap between asthma guidelines and actual management with decreased healthcare consultations and dispensations of asthma medications after the transition to adult healthcare among young people with asthma. How health-related quality of life (HRQoL) develops during the transition from adolescence to young adulthood is unclear. Our aim was therefore to investigate HRQoL among young people with asthma during the transition to adulthood. Further, to assess if level of asthma control and physical activity influence any potential association between asthma and HRQoL. METHODS The study population consisted of 2268 participants from the ongoing Swedish population-based prospective birth cohort BAMSE (Barn/Child, Allergy, Milieu, Stockholm, Epidemiology). HRQoL was measured using the instrument EQ-5D-3 L and three general questions. The EQ-5D-3 L consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-3 L instrument and questions on general health, symptoms and treatment of asthma, and lifestyle factors were based on data from follow-ups at 16 and 24 years. Cross-sectional analyses were made. RESULTS At the 24-year follow-up, the adjusted median values of EQ VAS were lower compared with at the 16-year follow-up; among both participants with asthma (80 vs. 85, p < 0.01) and those without asthma (80 vs. 87, p < 0.01). At the 24-year follow-up, participants with uncontrolled asthma had a lower adjusted median EQ VAS score than peers with controlled/partly controlled asthma (75 vs. 80, p = 0.03). Further, young adults with asthma who did not fulfil the WHO recommendations on physical activity had lower EQ VAS scores than peers who did (70 vs. 80, p < 0.01). CONCLUSION HRQoL is lower in young adulthood than in adolescence. Young adults with asthma having uncontrolled disease or who are physically inactive appear to be particularly vulnerable.

Abstract
Purpose Critical asthma outcomes highlighted in clinical guidelines include asthma-related quality of life, asthma exacerbations, and asthma control. An easy-to-implement measure of asthma control that assesses both symptom impairment and exacerbation risk and reflects the impact of asthma on patients' lives is lacking. Hence, the objective of this study was to assess the Asthma Impairment and Risk Questionnaire (AIRQ®) construct validity relative to patient self-perception of asthma status and validated disease-specific patient-reported outcome (PRO) measures. Patients and methods Baseline data were analyzed from patients (aged ≥ 12 years) with asthma participating in a 12-month observational study assessing the ability of AIRQ to predict exacerbations. At entry, patients completed a sociodemographic questionnaire, AIRQ, 3 questions addressing self-perceived asthma status, Saint George's Respiratory Questionnaire (SGRQ), mini-Asthma Quality of Life Questionnaire (AQLQ), and Adult Asthma Adherence Questionnaire (AAAQ). Descriptive statistics were calculated for demographic and clinical characteristics. AIRQ construct validity was evaluated by assessing correlations between total AIRQ score and patient self-assessments, SGRQ, mini-AQLQ, and AAAQ scores. Comparisons of SGRQ, mini-AQLQ, and AAAQ total and component/domain scores by AIRQ control category were performed using general linear models and Scheffe's post hoc adjustments for pairwise comparisons. Results A total of 1112 patients were enrolled: 70% female, 78% White, mean (standard deviation) age 43.9 (19.5) years. There were highly significant correlations between AIRQ score and patient self-perception of overall control (r = 0.69; p < 0.001), total SGRQ (r = 0.74, p < 0.001), and mini-AQLQ (r = -0.78, p < 0.001) scores. As AIRQ control category worsened, so did total and domain SGRQ, mini-AQLQ, and AAAQ impediment-to-inhaled-corticosteroid-adherence scores (all pairwise comparisons p < 0.001). Conclusion Findings demonstrate the construct validity of AIRQ relative to patient self-perception of asthma status, disease-specific PRO measures, and treatment adherence barriers. AIRQ can be a useful instrument to raise awareness of the unrecognized impacts of asthma on patients' lives.

Abstract
Asthma, a common airway disease, results in a significant burden to both patients and society worldwide. Yet, despite global political commitment backed by the United Nations, progress to reduce the burden of asthma remains inadequate. This is particularly true in low-income countries. To date, progress has been delayed by the lack of uniform data collection, imperfect surveillance methods, inadequate resources, poor access to effective therapies, substandard asthma education, ineffective governmental policies, rapid urbanization, progressive increase in asthma prevalence, increased life expectancy and obesity rates worldwide, asthma heterogeneity and disease complexity, smoking, and environmental exposures to allergens and pollution. A thorough understanding of the challenges facing the international community is essential to define future strategies to improve the burden of asthma.

Abstract
BACKGROUND Safety and efficacy data for dupilumab beyond 1 year are lacking for patients from Japan with moderate-to-severe asthma. METHODS The TRAVERSE open-label extension (OLE) study (NCT02134028) assessed the safety and efficacy of dupilumab 300 mg every 2 weeks up to 96 weeks in 2282 patients who completed a previous dupilumab asthma study. The primary endpoint was incidence of treatment-emergent adverse events (TEAEs). Secondary endpoints included annualized severe exacerbation rate and change from parent study baseline in pre-bronchodilator forced expiratory volume in 1 second (FEV1), asthma control, quality of life, and blood eosinophil levels. Anti-drug antibodies (ADA) were evaluated. We report results in 160 (7.8% of exposed population) patients recruited from Japanese centers with non-oral corticosteroid (OCS)-dependent asthma rolled over from two parent studies, and in subgroups with a type 2 inflammatory phenotype. RESULTS TEAEs were consistent with the parent studies and the known safety profile of dupilumab. One patient permanently discontinued treatment due to TEAEs. Exacerbation rates remained low and were sustained to Week 96, as were improvements in pre-bronchodilator FEV1. Rapid, sustained improvements were observed in dupilumab-treated patients who previously received placebo in a parent study, while further improvements in exacerbation rates, asthma control, and asthma-related quality of life were observed in those continuing dupilumab. Blood eosinophil levels decreased progressively while on treatment. Treatment-emergent ADA responses were highest in patients who had previously received placebo. Efficacy results were consistent in patients with a type 2 phenotype. CONCLUSIONS Long-term dupilumab treatment was well tolerated and efficacious in patients with non-OCS-dependent, moderate-to-severe asthma recruited from Japan.

Abstract
BACKGROUND Previous studies indicate that suboptimal medication adherence may contribute to uncontrolled asthma. Global Initiative for Asthma (GINA) guidelines recommend treatment escalation to biologics for patients with uncontrolled asthma despite adherence to high-dose maintenance medication and who have eosinophilic/allergic biomarkers or require maintenance oral corticosteroids. OBJECTIVE This study aimed to describe the clinical status of patients with asthma escalated to biologic therapy. METHODS This retrospective claims database analysis enrolled US patients with asthma who were escalated to biologics between January 2016 and June 2020. Exacerbations, control status, GINA step, and maintenance medication adherence during the 12 months before biologic therapy initiation were analyzed. Asthma control was assessed using both the European Respiratory Society/American Thoracic Society (ERS/ATS) and Stempel criteria. Adherence was defined as the proportion of days covered (PDC) by maintenance medication claims. RESULTS Of 1786 patients escalated to biologics, 506 were included for analysis. During the 12 months before escalation, 346 patients had confirmed exacerbations. Uncontrolled asthma status was estimated in 55% and 70% of patients (ERS/ATS and Stempel criteria, respectively). GINA step was inferred for 395 patients: 154 were at step 2, 11 at step 3, 104 at step 4, and 126 at step 5. Of 403 patients with maintenance medication claims, 63% had suboptimal maintenance medication adherence (PDC <80%). CONCLUSION In this study, most patients initiating biologic therapy had mild-to-moderate asthma or suboptimal maintenance medication adherence, possibly indicating inappropriate escalation. Incorporating objective medication adherence monitoring into existing guidelines may reduce inappropriate escalation to biologics.

Abstract
BACKGROUND Treatment guidelines recommend triple therapy for patients with asthma who remain uncontrolled on inhaled corticosteroid/long-acting β2-agonist therapy. Previously, triple therapy was only available via multiple inhalers. Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) is approved as maintenance treatment for asthma; however, real-world information on adherence and persistence is limited. OBJECTIVE To compare adherence and persistence among adult patients with asthma receiving single-inhaler FF/UMEC/VI versus multiple-inhaler triple therapy (MITT) in the United States. METHODS This retrospective cohort study used IQVIA PharMetrics Plus data to evaluate patients with asthma who initiated once-daily FF/UMEC/VI 100/62.5/25 mcg or MITT between September 18, 2017, and September 30, 2019. Inverse probability weighting and multivariable regression adjusted for differences in characteristics between the FF/UMEC/VI and MITT cohorts. Adherence was assessed using proportion of days covered (PDC) and proportion of patients achieving PDC ≥0.8 and PDC ≥0.5. Non-persistence was identified as a >45-day gap between fills. RESULTS The study included 1396 FF/UMEC/VI and 5115 MITT initiators. Three months after initiation, FF/UMEC/VI users had significantly higher mean PDC versus MITT users (0.68 vs 0.59; P < .001) and 31% more likely to be adherent (PDC ≥0.8; 40.6% vs 31.3%; adjusted risk ratio [95% confidence interval (CI)]: 1.31 [1.13-1.54]; P < .001). Similar patterns were observed at 6 and 12 months post initiation. In addition, FF/UMEC/VI users were 49% more likely to persist at 12 months than MITT users (25.9% vs 15.1%, adjusted hazard ratio [95% CI]: 1.49 [1.39-1.60]; P < .001). CONCLUSIONS Patients with asthma initiating triple therapy with FF/UMEC/VI had significantly better adherence and persistence compared with MITT initiators.

Abstract
Patients with asthma who are suboptimally responsive to inhaled corticosteroids (ICS) and long-acting β2-agonists (LABAs) are frequently exposed to oral corticosteroids and high-dose ICS, which can lead to significant side effects. Long-acting muscarinic antagonists (LAMAs) have demonstrated efficacy and safety in a subset of these patients. This review summarizes the results of key studies using LAMAs in patients with asthma aged 12 years or older. LAMA as an add-on treatment improved lung function and asthma control in patients with uncontrolled asthma across studies. The efficacy of LAMAs as an add-on to ICS was superior to that of placebo and ICS dose escalation and comparable with that of LABAs. LAMA plus ICS plus LABA provided modest improvements in bronchodilation and increased the time to first severe exacerbation versus ICS plus LABA. Single-inhaler triple therapy was associated with decreased health care resource utilization and improved cost-effectiveness versus multiple inhalers. LAMAs were generally well tolerated; asthma exacerbations, bronchitis, and nasopharyngitis were common adverse events with LAMA in combination with ICS alone or ICS plus LABA. Thus, the overall evidence presented in this review supports the use of add-on LAMA treatment as a reasonable option in patients with asthma uncontrolled with ICS plus LABA or ICS alone.

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. Asthma is a heterogenous disease. Targeted therapies have been developed based on the pathophysiology of type 2 inflammation. These therapies offer hope for improved management of type 2 inflammatory airway diseases.https://bit.ly/3HCkrvQ

Abstract
Inhaled medication is essential to control asthma and COPD, but availability and proper adherence are challenges in low-middle income countries (LMIC). Data on medication availability and adherence in Central Asia are lacking. We aimed to investigate the availability of respiratory medication and the extent of financially driven non-adherence in patients with COPD and asthma in Kyrgyzstan. A cross-sectional study was conducted in two regions of Kyrgyzstan. Patients with a physician- and spirometry confirmed diagnosis of asthma and/or COPD were included. The main outcomes were (1) availability of respiratory medication in hospitals and pharmacies, assessed by a survey, and (2) medication adherence, assessed by the Test of Adherence to Inhalers (TAI). Logistic regression analyses were used to identify predictors for adherence. Of the 300 participants (COPD: 264; asthma: 36), 68.9% were buying respiratory medication out-of-pocket. Of all patients visiting the hospital, almost half reported medication not being available. In pharmacies, this was 8%. Poor adherence prevailed over intermediate and good adherence (80.7% vs. 12.0% and 7.3%, respectively). Deliberate and erratic non-adherence behavior patterns were the most frequent (89.7% and 88.0%), followed by an unconscious non-adherent behavioral pattern (31.3%). In total, 68.3% reported a financial reason as a barrier to proper adherence. Low BMI was the only factor significantly associated with good adherence. In this LMIC population, poor medication availability was common and 80% were poorly adherent. Erratic and deliberate non-adherent behaviors were the most common pattern and financial barriers play a role in over two-thirds of the population.

Abstract
Nuclear receptors are a unique family of transcription factors that play cardinal roles in physiology and plethora of human diseases. The adopted orphan nuclear receptor Nr1d1 is a constitutive transcriptional repressor known to modulate several biological processes. In this study, we found that Nr1d1 plays a decisive role in T helper (Th)-cell polarization and transcriptionally impedes the formation of Th2 cells by directly binding to the promoter region of GATA binding protein 3 (GATA3) gene. Nr1d1 interacts with its cellular companion, the nuclear receptor corepressor and histone deacetylase 3 to form a stable repression complex on the GATA3 promoter. The presence of Nr1d1 also imparts protection against associated inflammatory responses in murine model of asthma and its ligand SR9011 eased disease severity by suppressing Th2 responses. Moreover, Chip-seq profiling uncovered Nr1d1 interactions with other gene subsets that impedes Th2-linked pathways and regulates metabolism, immunity and brain functions, therefore, providing empirical evidence regarding the genetic link between asthma and other comorbid conditions. Thus, Nr1d1 emerges as a molecular switch that could be targeted to subdue asthma.

Abstract
BACKGROUND Recurrent assessment of asthma control is essential to evaluating disease stability and intervention impacts. An assessment that can be administered between annual clinic visits is needed. The Asthma Impairment and Risk Questionnaire (AIRQ) is a cross-sectionally validated, 10-item, yes or no, composite control tool evaluating previous 2-week symptoms and previous 12-month exacerbations. OBJECTIVE To evaluate the construct validity of the AIRQ using a 3-month recall period for exacerbation-based risk questions and retaining the 2-week recall for symptom-based impairment items. METHODS At baseline, patients completed the AIRQ with 12-month recall exacerbation items, Asthma Control Test (ACT), St. George's Respiratory Questionnaire (SGRQ), and global self-assessments of asthma risk, control, and symptom severity. Patient-reported exacerbations were captured monthly. The AIRQ with 3-month recall exacerbation items, ACT, and global self-assessments was administered at months 3, 6, and 9, and SGRQ at month 6. RESULTS A total of 1112 patients aged 12 years or older were enrolled (mean [SD] age, 43.9 [19.5] years). The AIRQ and each administration of the AIRQ with 3-month recall exacerbation items classified asthma control similarly to an ACT plus exacerbation validation standard. For both AIRQ versions, SGRQ scores were higher with worsening asthma control (P < .001). At months 3, 6, and 9, worse AIRQ control levels were associated with higher proportions of patients with 1 or more and 2 or more exacerbations in the previous 3 months and patient global self-assessments indicating greater asthma morbidity (all P < .001). CONCLUSION The AIRQ using exacerbation risk items with a 3-month recall period exhibits construct validity for classifying current asthma control and can be administered between annual AIRQ assessments.

Abstract
Background and objective Asthma is a chronic recurring respiratory disease, and its prevalence is on the rise. A drop in the quality of life (QoL), as well as sleep problems, has been reported in asthmatic patients in the literature. This study was conducted to determine the relationship between QoL and sleep quality in asthmatic patients. Methods This cross-sectional study recruited 76 diagnosed asthmatic outpatients from our university clinic. The subjects completed the self-administered 36-Item Short-Form Health Survey QoL questionnaire (SF-36) and the Pittsburgh Sleep Quality Index (PSQI) assessment. Results The study results revealed poor sleep quality in 55 (72.4%) of the subjects. The total sleep quality scores significantly and negatively correlated with the physical and mental components of QoL (moderate, p=0.00). All QoL subscales were significantly higher in patients with good sleep quality (PSQI: <5, p<0.00). Logistic regression analysis showed that good sleep quality (modified) could predict a mental component score (MCS) of more than 64. Conclusion Poor sleep quality can bring down the scores of all QoL components in asthma patients and is the best predictor of their QoL. Therefore, sleep quality and QoL indicators could be applied as part of a better approach to classification, management, and control of asthma.

Abstract
The aim of this observational, retrospective study was to describe characteristics, treatment patterns, and adherence among patients with asthma who initiated multiple-inhaler triple therapy (MITT) in Catalonia, Spain. This study used data of patients initiating MITT in 2016 from the SIDIAP (Information System for Research in Primary Care) database, which covers ~80% of the Catalonian population (5.8 million). Of 1,204 patients initiating MITT, 361 (30.0%) stepped down (discontinued ≥ 1 and continued ≥1 MITT component) and 89 (7.4%) stopped all three components of MITT for a period of 60 days during the following 12 months. In the follow-up period, 196 (16.3%) patients were considered adherent to MITT (>0.8 proportion of days covered [PDC]), with a mean (standard deviation) PDC of 0.52 (0.51) days. Given the low adherence and substantial rates of step down/discontinuation among patients initiating MITT, there is an urgent need to implement strategies to improve treatment adherence/persistence.

BACKGROUND While effective asthma control medications reduce the burden of asthma, a significant subgroup of these treatments, namely metered-dose inhalers (MDIs), produce substantial greenhouse gas (GHG) emissions, thus contributing to climate change. This study quantified the global climate impact (i.e. carbon dioxide equivalent [CO2e] emissions) and costs of long-term status quo asthma inhaler use versus alternative scenarios substituting MDIs with propellant-free dry powder inhalers (DPIs). METHODS Three scenarios were evaluated across 10-year (2020-2030) and 50-year (2020-2070) time horizons: A (status quo inhaler use), B and C (2% and 5% year-over-year substitution of MDIs with DPIs, respectively). Global inhaler volumes and costs at baseline were sourced from IQVIA, then projected using UN and WHO trends in per capita GDP, urbanization, and asthma population growth. Inhaler spending was assumed to fall by 90% following generic entry in 2030. The carbon footprint per inhaler and health damage factors for disability-adjusted life years (DALYs) were derived from literature. The US government's central and high-impact estimates for the social cost of carbon (SCC) were used to calculate emissions costs. RESULTS Over 50 years, scenario A resulted in 826 million tonnes of CO2e emissions globally, with an associated SCC between 21% and 65% of the projected global spending on asthma inhalers. In comparison, CO2e emissions were reduced by 38% and 58% in Scenarios B and C, respectively, and DALYs improved by 33 and 51%. Depending on SCC estimates, Scenarios B and C increased global costs by 7.3% and 16.5%, respectively (central SCC), or decreased costs by 4.2% and 2.6% (high-impact SCC) versus Scenario A. Over 10 years, Scenario A resulted in 97 million tonnes of CO2e emissions globally, with an associated SCC between 4.4% and 12.2% of projected spending. In comparison, Scenarios B and C were associated with 12% and 24% reductions in CO2e emissions and improvements in DALYs by 11.5% and 22.7%, respectively. CONCLUSIONS Global efforts by environmental and health-policy decision-makers to substitute currently available MDIs with DPIs for asthma control would result in substantial reductions in GHG emissions with manageable costs, or potential cost savings, depending on the SCC. Policies that decrease use of MDIs warrant global attention.

Abstract
BACKGROUND There are limited published data on the burden of moderate/severe uncontrolled asthma. METHODS We conducted a systematic literature review to better understand the impact of moderate-to-severe asthma in the US, the UK, Germany, France, Italy, Spain, Canada, Japan, and Australia in terms of prevalence, clinical measures, health-related quality of life (HRQoL) and economic burden, for patients whose asthma is uncontrolled despite inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) therapy. RESULTS The prevalence of uncontrolled asthma among patients with moderate/severe disease varied but was as high as 100% in some subgroups. Patients with uncontrolled asthma generally had poor lung function (mean/median pre-bronchodilator forced expiratory volume in 1 second [FEV1]: 1.69-2.45 L; mean/median pre-bronchodilator percent predicted FEV1: 57.2-79.7). There was also a substantial but variable exacerbation burden associated with uncontrolled asthma, with the annualised rate of exacerbations ranging from 1.30 to 7.30 when considering various patient subgroups. Furthermore, the annualised rate of severe exacerbations ranged from 1.66 to 3.60. The HRQoL burden measured using disease-specific and generic instruments consistently demonstrated substantial impairment of HRQoL for those with uncontrolled asthma; Asthma Quality of Life Questionnaire scores ranged from 3.00 to 5.20, whilst EurQol-5 Dimensions index scores ranged from 0.53 to 0.59. Direct, indirect and total costs together with consumption of other healthcare resources associated with managing uncontrolled asthma were also substantial in the population studied; no caregiver burden was identified. CONCLUSIONS Our findings suggest that significant unmet needs exist for patients with uncontrolled asthma despite the availability of ICS/LABA therapy. Novel treatments are needed to help reduce the burden to patients, healthcare systems and society.

Abstract
BACKGROUND Addition of a long-acting muscarinic antagonist is recommended for patients with asthma uncontrolled on inhaled corticosteroid/long-acting β2-agonist therapy. This is the first large-scale, real-world study examining multiple-inhaler triple-therapy (MITT) use in asthma. OBJECTIVE To describe real-world prevalence, outcomes, and treatment patterns associated with MITT. METHODS This retrospective cohort study used medical and pharmacy claims from the Optum Research Database. Patients were diagnosed with asthma between January 01, 2013, and July 31, 2018, with evidence of MITT use (≥1 overlapping days' supply of inhaled corticosteroid, long-acting β2-agonist, and long-acting muscarinic antagonist). Annual MITT prevalence (primary end point) was assessed in the prevalent population; eligible patients were 18 years or older with 2 or more asthma diagnoses during the study period, and continuous enrollment for the entire year. Secondary outcomes (adherence [proportion of days covered], MITT persistence, health care resource utilization, costs) were assessed in the incident MITT population; eligible patients were 18 years or older, with 2 or more asthma diagnoses and continuous enrollment during both the 12-month baseline and 12-month follow-up periods. Patients with chronic obstructive pulmonary disease or cystic fibrosis were excluded. RESULTS MITT prevalence was low but increased from 0.35% (95% CI, 0.32-0.37) in 2014/2015 to 1.00% (95% CI, 0.96-1.04) in 2017/2018. Among 1831 incident MITT users, there was a substantial disease burden, demonstrated by high health care resource utilization and exacerbation rates. Adherence and persistence to MITT was low (mean proportion of days covered, 0.31 ± 0.27), and 12% (n = 216) remained on MITT 12 months postinitiation. CONCLUSIONS Overall, MITT use among patients with asthma is low. Patients initiating MITT have substantial disease burden and significant unmet needs.

Abstract
PURPOSE This study aimed to determine the impact of MI on self-efficacy, beliefs about medicines and medication adherence among adolescents with asthma. METHOD This randomized controlled trial conducted on 52 adolescents with asthma referring to the Pediatric Medical Center in Tehran, Iran. They were randomly assigned to the control and intervention groups. The educational intervention consisted of 3 one-hour sessions per week, which was held individually in the areas of medication adherence, beliefs about medicines and self-efficacy. Four validated questionnaires including demographic characteristics, medication adherence, self-efficacy and beliefs about medicines were completed by self-report both before the MI and 40 days after the end of the intervention. RESULTS In the baseline, the two groups were homogeneous in terms of demographic characteristics and outcome measures. At the post-test, the mean scores of the three outcome measures in the intervention group were reported higher compared to the scores in the control group (p < 0.05). The difference between the mean scores in medication adherence, beliefs about medicines and self-efficacy in the post-test between the two groups, even with the elimination of the effect pre-test scores, were significant (p < 0.05). CONCLUSIONS The results of this study showed that MI can be effective in improving medication adherence, beliefs about medicines, and self-efficacy. PRACTICE IMPLICATIONS The primary goal in the treatment of patients with asthma is asthma control by using corticosteroids. MI is one of the interventions that can simultaneously provide motivation, readiness, beliefs about medicine and self-efficacy for behavioral changes (medication adherence) in patients with asthma.

Abstract
OBJECTIVE In CAPTAIN, a double-blind, parallel-group, Phase IIIA study, fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) improved lung function, symptoms and asthma control versus FF/VI in patients with inadequately controlled asthma. Here, we report efficacy and safety from a Japanese cohort in CAPTAIN. METHODS Adults with inadequately controlled asthma despite inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) were randomized (1:1:1:1:1:1) to once-daily FF/VI (100/25 mcg or 200/25 mcg) or FF/UMEC/VI (100/31.25/25 mcg, 100/62.5/25 mcg, 200/31.25/25 mcg, or 200/62.5/25 mcg) for ≥24 weeks. Endpoints included change from baseline in clinic trough FEV1 (primary), annualized rate of moderate/severe asthma exacerbations (key secondary), clinic FEV1 3 h post-dose, and Asthma Control Questionnaire (ACQ)-7, St George's Respiratory Questionnaire (SGRQ) (all Week 24), Evaluating Respiratory Symptoms (E-RS): Asthma total scores (Weeks 21-24) (all secondary). Adverse events and adverse events of special interest were monitored. Clinical trials.gov registry no: NCT02924688. RESULTS Overall, 229 of 2436 patients in the intention-to-treat (ITT) population were from Japan. In this cohort, change from baseline in trough FEV1 for FF/UMEC/VI 100/62.5/25 mcg versus FF/VI 100/25 mcg was 105 mL (95% confidence interval -5, 216) and 69 mL (-42, 179) for 200/62.5/25 mcg versus 200/25 mcg. These observations were supported by clinic FEV1 at 3 h post-dose. Moderate/severe exacerbation incidence was low and similar across pooled treatment groups (FF/VI, FF/UMEC 31.25 mcg/VI, FF/UMEC 62.5 mcg/VI). All pooled groups demonstrated clinically important improvements from baseline in ACQ-7, SGRQ and E-RS: Asthma total scores. Safety profiles were consistent with the overall ITT population, with no new safety concerns. CONCLUSION FF/UMEC/VI is an effective option with a favorable risk-benefit profile in Japanese patients with uncontrolled moderate or severe asthma on ICS/LABA.

Abstract
Background The objective of this analysis was to examine the association between asthma control (based on Asthma Control Test (ACT) responses) and healthcare resource utilisation (HRU), work productivity and health-related quality of life (HRQoL) among a nationwide sample of US adults with a self-reported diagnosis of asthma and without comorbid chronic obstructive pulmonary disease. Methods Data were obtained from the 2015 and 2016 self-administered, internet-based National Health and Wellness Surveys. Patients were grouped by ACT score (≤15: poorly controlled; 16–19: partly controlled; 20–25: well-controlled asthma). Study outcomes included HRU (patient-reported healthcare provider visits, emergency department visits and hospitalisations during the previous 6 months); work productivity, measured using the Work Productivity and Activity Impairment-General Health Scale; HRU-associated costs and work productivity loss and HRQoL, measured using EuroQoL-5 Dimensions-5 Levels (EQ-5D-5L) and the Short Form Health Survey-36V.2 (SF-36V.2). Incremental differences in outcomes between groups were assessed using generalised linear models adjusted for covariates. Results Of 7820 eligible adults, 17.4% had poorly controlled, 20.1% partly controlled and 62.5% well-controlled asthma. Well-controlled asthma was associated with significantly lower HRU (p<0.001) and lower mean direct costs ($6012 vs $8554 and $15 262, respectively; p<0.001); well-controlled asthma was also associated with significantly lower mean scores for work absenteeism, work presenteeism, overall work impairment and activity impairment (all p<0.001), and lower mean indirect costs ($6353 vs $10 448 and $14 764, respectively; p<0.001). Clinically meaningful differences favouring well-controlled asthma were seen for all HRQoL measures, with statistically significantly higher adjusted mean EQ-5D-5L index and SF-6D Health Utilities Index scores (derived from SF-36V.2) for patients with well-controlled asthma compared with partly controlled or poorly controlled asthma (p<0.001). Conclusions The study demonstrates a clear relationship between asthma control and its impact on HRU, costs, work productivity and HRQoL. This will allow for better identification and management of patients with poorly controlled asthma.

Abstract
Purpose The pivotal CAPTAIN study reported a favorable safety profile with once-daily inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist (ICS/LAMA/LABA) triple combination of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in patients with inadequately controlled asthma, some of whom were Japanese. Here, we evaluate the long-term (52 weeks) safety of FF/UMEC/VI in Japanese patients with asthma. Patients and Methods This was a Phase III, 52-week, multicenter, non-comparator, non-randomized, open-label study (NCT03184987) in Japanese adults receiving maintenance therapy with ICS/LABA, with or without LAMA. At enrollment, patients were allocated to either FF/UMEC/VI 100/62.5/25mcg (Group 1) or 200/62.5/25mcg (Group 2). Patients in Group 1 could have their treatment stepped up to 200/62.5/25mcg at Week 24 if their Asthma Control Questionnaire (ACQ)-7 score was >0.75. The primary endpoint was the incidence of adverse events (AEs) and serious AEs (SAEs). Secondary endpoints included vital signs, electrocardiogram measurements, and clinical laboratory tests (biochemistry, hematology, urinalysis). Efficacy was assessed as "other" endpoints. Results A total of 111 Japanese patients were included in the intention-to-treat (ITT) population. Overall, 77 (69%) patients reported ≥1 AE (Group 1: n=30 [64%]; step-up group: n=7 [78%]; Group 2: n=40 [73%]). SAEs were reported for 1 (2.1%) and 2 (3.6%) patients in Groups 1 and 2, respectively. All SAEs were considered unrelated to study treatment. One AE and one SAE led to study withdrawal: oropharyngeal discomfort (Group 1); eosinophilic granulomatosis with polyangiitis (Group 2). No new safety concerns were identified throughout the 52-week treatment period. Conclusion In this uncontrolled open-label study, no new safety concerns were observed with long-term (52 weeks) treatment with once-daily FF/UMEC/VI among 111 Japanese patients with asthma.

Abstract
Rationale The National Heart, Lung, and Blood Institute (NHLBI) recommend a stepwise approach to asthma management, with the goals of maintaining asthma control and reducing exacerbations. Although asthma treatments reduce the frequency of exacerbations, they still occur. We aimed to characterize the treated United States of America (US) adult asthma population, including those experiencing exacerbations, in terms of socio-demographics, clinical characteristics, and healthcare resource utilization (HRU). Patients and Methods A retrospective cohort of asthma patients aged ≥18 years on 01 January 2014 with ≥1 ICD-9 asthma code (493.xx) enrolled in a US healthcare claims database during 2013–2014. Patients who had ≥2 asthma medication dispensings during 2013 (baseline), including ≥1 in the 90-day period before index date, were classified according to NHLBI step. Patients with chronic obstructive pulmonary disease, cystic fibrosis, or lung cancer diagnoses were excluded. Demographics, comorbidities, clinical characteristics, and HRU were described during baseline. Exacerbations and HRU were described during 2014 (follow-up period). Results In total, 72,156 patients were included; 10,590 (14.7%) had ≥1 exacerbation during follow-up. Approximately 44% of patients were classified as NHLBI Steps 1–2, 41% as Steps 3–4, and 11% as Steps 5–6. Exacerbation frequency increased with step (Steps 1, 2, and 3: 12–14%; Steps 4, 5, and 6: 16–26%). Compared with the overall population during baseline, patients with an exacerbation had similar demographics, but differences were observed for comorbid allergic rhinitis (46.4% vs 40.1%, respectively), blood eosinophil counts ≥300 cells/μL (45.5% vs 39.6%, respectively), and asthma-related healthcare encounters (62.9% vs 52.4%, respectively). Overall, asthma-related HRU during follow-up increased with NHLBI step. Conclusion Exacerbations were observed among patients classified at each NHLBI step and were more frequent with increasing step. Exacerbations and asthma-related HRU highlight the continued unmet need in the treated US asthma population.

Abstract
OBJECTIVE Despite advances in treatment, asthma remains uncontrolled in many patients, with increased risk of exacerbation and associated healthcare resource utilization (HCRU). We describe patient characteristics, exacerbations, asthma control, and HCRU using GINA treatment step (GS) as a proxy for asthma severity. . METHODS Using a large, US, health-claims database, 4 longitudinal cohorts of 517,738 patients in GS2-5, including a subgroup of patients with baseline eosinophil (EOS) counts, were analyzed retrospectively (study period 2010 - 2016). Index for each cohort was patients' first time entering the GS, determined by first claim of first regimen. Uncontrolled asthma was defined according to published criteria as a multi-dimensional measure that includes number of exacerbations. Key variables including, baseline characteristics, post-index exacerbations, and HCRU (all-cause and asthma-specific events) are summarized by descriptive statistics. RESULTS Uncontrolled asthma was reported in 19.8% patients in GS2, 44.8% in GS3, 49.3% in GS4, and 58.6% in GS5. Annualized mean (SD) rates of exacerbation 12 months post-index generally increased across GS2-5 (0.26 [0.86], 0.32 [0.79], 0.36 [0.83], 0.29 [0.86], respectively). HCRU also increased with increasing GS, with higher HCRU among the uncontrolled cohort within each GS. In patients with EOS ≥300 cells/µL, uncontrolled asthma also increased with increasing GS (21.8%, 43.9%, 50.5%, 67.2% for GS2-5, respectively). CONCLUSIONS This large database study provides real-world evidence of the substantial degree of uncontrolled asthma in US clinical practice across GS, supporting calls for better asthma management. Healthcare burden tends to increase with lack of control in all groups, highlighting the need for improved patient education, adherence, access, and treatment optimization.

Abstract
BACKGROUND This analysis aimed to characterize the pharmacokinetics (PK) of the inhaled corticosteroid (ICS) fluticasone furoate (FF), the long-acting muscarinic antagonist umeclidinium (UMEC), and the long-acting β2-agonist (LABA) vilanterol (VI), administered as dual (FF/VI) or triple (FF/UMEC/VI) single-inhaler therapy to patients with asthma, and to identify covariates that may influence the PK of each analyte. METHODS Blood samples were obtained from the phase IIIA CAPTAIN study (ClinicalTrials.gov: NCT02924688), which evaluated the efficacy and safety of once-daily FF/UMEC/VI versus FF/VI in patients with uncontrolled asthma taking ICS/LABA. Samples were collected at trough (defined as ≥ 20 h after the last dose) from all subjects randomized to the six treatment groups (FF/UMEC/VI 100/31.25/25 μg, 100/62.5/25 μg, 200/31.25/25 μg, 200/62.5/25 μg; FF/VI 100/25 μg, 200/25 μg) at week 24 or the early withdrawal visit. In a subset of patients, PK samples were obtained predose at week 12, and at 5-30 min, 45-90 min, and 2-3 h postdose. For each analyte, a population PK model was developed using non-linear mixed-effects modeling. The maximum likelihood method was utilized to incorporate data below the quantifiable limit (BQL). Final models were used to derive the area under the plasma concentration-time curve and maximum observed concentration at steady-state for each analyte. RESULTS We obtained 4018, 2695, and 4032 samples from 1891, 1258, and 1891 patients, for FF, UMEC, and VI, respectively; 48%, 49%, and 50% of samples were reported as BQL for each analyte, respectively. The PK were adequately described by a two-compartment model with first-order absorption and elimination for FF, a two-compartment model with intravenous bolus input and first-order elimination for UMEC, and a three-compartment model with zero-order input and first-order elimination for VI. Statistically significant covariates were body weight on apparent inhaled clearance of FF, creatinine clearance on apparent clearance and body weight on apparent inhaled volume of distribution of the central compartment for UMEC, and race (East Asian, Japanese, and South East Asian heritage) on inhaled apparent volume of distribution of the central compartment for VI. However, the overall effects of covariates were marginal and thus do not warrant dose adjustment. Systemic exposures of FF or VI did not differ when administered as a single-inhaler triple (FF/UMEC/VI) or dual combination (FF/VI), and were similar to those reported for patients with chronic obstructive pulmonary disease. CONCLUSION Only marginal covariate effects were observed, and thus no dose adjustments are deemed necessary for FF, UMEC, or VI. There was no difference in FF or VI systemic exposure in patients with asthma when administered as either triple (FF/UMEC/VI) or dual therapy (FF/VI). Together with efficacy findings from the CAPTAIN study, our data support the use of single-inhaler FF/UMEC/VI triple therapy for patients with uncontrolled asthma currently receiving ICS/LABA.

Abstract
BACKGROUND AND AIMS Severe asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS) which worsen patients' health and increase healthcare spending. Aim of this study was to assess the clinical and economic effect of adding mepolizumab (MEP) for the treatment of these patients. METHODS Patients >18 years old, referred to 8 asthma clinics, starting MEP between May 2017 and December 2018, were enrolled and followed-up for 12 months. Information in the 12 months before mepolizumab were collected retrospectively. The evaluation parameters included: OCS use, number of exacerbations/hospitalizations, concomitant therapies, comorbidity, and annual number of working days lost due to the disease. The primary objective was to compare the annual total cost per patient pre- and post-MEP. Secondary outcomes included rates of exacerbations and number of OCS-dependent patients. RESULTS 106 patients were enrolled in the study: 46 male, median age 58 years. Mean annual cost pre- and post-MEP (cost of biologic excluded) was €3996 and €1,527, respectively. Total savings due to MEP resulted in €2469 (95%CI 1945-2993), 62% due to exacerbations reduction and 33% due to productivity increase. Such savings could fund about 22% of the total cost of MEP for one year. The introduction of MEP induced a clinical benefit by reducing both OCS-dependent patients (OR = 0.12, 95%CI 0.06-0.23) and exacerbation rate (RR = 0.19, 95%CI 0.15-0.24). CONCLUSIONS Patients with severe eosinophilic asthma experienced a clinical benefit in asthma control adding MEP to standard therapy. Biologic therapy can be, partially, funded by the savings produced by patients' improvement.

Abstract
BACKGROUND Persistent allergic airway diseases cause a great burden worldwide. Their pathogenesis is not clear enough. There is evidence that one of the recently described cytokine interleukin (IL) 22 may be involved in the pathogenesis of these diseases. Scientists argue if this cytokine acts as proinflammatory or anti-inflammatory agent. The aim of this study was to investigate IL-22 level in patients with persistent allergic airway diseases caused by house dust mite (HDM) in comparison with healthy individuals and to evaluate its relationship with IL-13 and IL-10 level, symptoms score and quality of life. METHODS Patients with persistent allergic rhinitis caused by HDM and having symptoms for at least 2 years with or without allergic asthma were involved into the study. Measurements of IL-22, IL-13 and IL-10 and in serum and nasal lavage was performed by ELISA. Questionnaires assessing symptoms severity and quality of life were used. RESULTS A tendency was observed that IL-22 in serum and nasal lavage was higher in patients with allergic airway diseases compared to control group (14.86 pg/ml vs. 7.04 pg/ml and 2.67 pg/ml vs. 1.28 pg/ml, respectively). Positive statistically significant correlation was estimated between serum IL-22 and serum IL-10 (rs = 0.57, p < 0.01) and IL-13 (rs = 0.44, p < 0.05) level. Moreover, positive significant correlation was found between IL-22 in nasal lavage and IL-10 in nasal lavage (rs = 0.37, p < 0.05). There was a negative statistically significant correlation between serum IL-22 and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) (rs = - 0.42, p < 0.05). CONCLUSION Our study showed a possible anti-inflammatory effect of IL-22 in patients with persistent allergic airway diseases caused by HDM.

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 Approximately 30% to 50% of patients with moderate/severe asthma have inadequately controlled disease despite adherence to inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) therapy. Data on prevalence and burden of uncontrolled asthma in specialty settings are lacking. OBJECTIVE To evaluate the prevalence and burden of uncontrolled asthma in respiratory specialist clinics in the United States. METHODS Adults with physician-diagnosed asthma attending pulmonary and allergy clinics with self-reported ICS use in the previous 4 weeks completed an electronic questionnaire including the Asthma Control Test and St George's Respiratory Questionnaire. Additional information was collected using an electronic case report form. RESULTS Of 774 patients attending 12 pulmonary and 12 allergy clinics, 53% were not well controlled (mean [SD] Asthma Control Test, 14.3 [3.6] vs 22.4 [1.6] in well-controlled patients). Among ICS/LABA users, 56% were not well controlled, which increased with increasing ICS dose (low-dose 45.7%; high-dose 59.7%). The not well-controlled group reported more respiratory illnesses, more comorbidities, and poorer health-related quality of life (mean [SD] St George's Respiratory Questionnaire, 46.1 [18.9] vs 19.8 [12.9] in the well-controlled group). These patients also had more asthma exacerbations (≥1 exacerbation, 68.9% vs 43.1%) and increased health care resource utilization (≥1 asthma-related hospitalization, 10.7% vs 2.7%); 27.3% were also receiving systemic corticosteroids. Approximately 40% of the population were eligible for step-up to ICS/LABA/long-acting muscarinic antagonist triple therapy, and 20% were eligible for biologic therapy. CONCLUSION Substantial unmet needs exist among patients with inadequately controlled asthma managed in United States specialist settings, which may be addressed by improved patient and physician education, better guideline implementation, and improved adherence.

Abstract
OBJECTIVE The asthma control test (ACT) is commonly used to identify patients with uncontrolled asthma. The goal of this study was to determine whether clinical parameters such as asthma history and medications, exacerbation rate, comorbidities, lung function, and socioeconomic status are risk factors for uncontrolled asthma assessed with the ACT, and to evaluate the psychological status of controlled and uncontrolled asthmatics. METHODS Adult asthmatics (n = 104) were recruited from a single asthma center, Poland. Asthma control was assessed with the ACT, using <20 as the cutoff point for uncontrolled asthma. Data on clinical factors were collected and spirometry was performed. Patients completed the Asthma Quality of Life Questionnaire, General Health Questionnaire, Acceptance of Illness Scale, Life Orientation Test-Revised, and Eysenck's Personality Inventory. RESULTS Asthma was uncontrolled in 42.3% of patients. Asthma exacerbations in the preceding 12 months and high inhaled corticosteroid (ICS) doses were identified as independent risk factors for uncontrolled asthma. Uncontrolled asthmatics had a significantly worse psychological status than controlled asthmatics. The groups did not differ in terms of personality traits, but in the controlled asthma group numerous significant correlations between psychological factors and personality traits were observed. In the uncontrolled asthma group, however, the occurrence of correlations between personality traits and other psychological variables was rarer. CONCLUSIONS The study identified independent risk factors for uncontrolled asthma, namely, exacerbations in the recent 12 months and treatment with high-dose ICS. Uncontrolled asthmatics have a significantly worse psychological status than controlled asthmatics, irrespective of personality traits.

Abstract
Background Asthma is an important cause of morbidity and mortality worldwide. Education is a critical component in the management of asthma. Objective This study sought to assess the impact of pharmacist-led educational interventions on asthma control and adherence. Setting Tertiary Hospitals in Nigeria Method This was a single-blind, three-arm, prospective, randomised, controlled, parallel-group study conducted in the Respiratory Units of the University of Nigeria Teaching Hospital, Enugu State and the Lagos University Teaching Hospital, Lagos State between March 2016 and September 2017. The three arms were: Usual Care, Individual Intervention, Caregiver-assisted Intervention (1:1:1 ratio). The Intervention arms received education for 6 months while the Usual Care arm received no education. The Asthma Control Test and the 8-item Morisky Medication Adherence Scale were filled at baseline, 3 months, and 6 months after baseline. Data were analyzed using the IBM SPSS Version 25.0 with statistical significance set as P < 0.05. Main outcome measure Asthma control and adherence. Results Seventy-eight (78) asthma patients participated; thirty-nine (39) per hospital; thirteen (13) in each arm. The Individual Intervention arm possessed significantly better asthma control compared to Usual Care at 3 months (21.42 Vs. 18.85; P = 0.004, t = 3.124, df = 25, 95% confidence interval = 0.88 - 4.28) and 6 months (21.81 Vs. 19.58; P = 0.003, t = 3.259, df = 25, 95% confidence interval = 0.82 - 3.64). The Individual Intervention arm also possessed significantly better adherence compared to Usual Care at 3 months (6.81 Vs. 4.94; P = 0.001, t = 3.706, df = 25, 95% confidence interval = 0.83 - 2.90) and 6 months (7.28 Vs. 5.13; P < 0.001, t = 4.094, df = 25, 95% confidence interval = 1.07 -3.24). The Caregiver-assisted Interventions had no significant improvement in asthma control and adherence. Conclusion The individualized educational interventions produced better improvements in asthma control and adherence.

Abstract
BACKGROUND Despite inhaled corticosteroid plus long-acting β2-agonist (ICS/LABA) therapy, 30-50% of patients with moderate or severe asthma remain inadequately controlled. We investigated the safety and efficacy of single-inhaler fluticasone furoate plus umeclidinium plus vilanterol (FF/UMEC/VI) compared with FF/VI. METHODS In this double-blind, randomised, parallel-group, phase 3A study (Clinical Study in Asthma Patients Receiving Triple Therapy in a Single Inhaler [CAPTAIN]), participants were recruited from 416 hospitals and primary care centres across 15 countries. Participants were eligible if they were aged 18 years or older, with inadequately controlled asthma (Asthma Control Questionnaire [ACQ]-6 score of ≥1·5) despite ICS/LABA, a documented health-care contact or a documented temporary change in asthma therapy for treatment of acute asthma symptoms in the year before screening, pre-bronchodilator FEV1 between 30% and less than 85% of predicted normal value, and reversibility (defined as an increase in FEV1 of ≥12% and ≥200 mL in the 20-60 min after four inhalations of albuterol or salbutamol) at screening. Participants were randomly assigned (1:1:1:1:1:1), via central based randomisation stratified by pre-study ICS dose at study entry, to once-daily FF/VI (100/25 μg or 200/25 μg) or FF/UMEC/VI (100/31·25/25 μg, 100/62·5/25 μg, 200/31·25/25 μg, or 200/62·5/25 μg) administered via Ellipta dry powder inhaler (Glaxo Operations UK, Hertfordshire, UK). Patients, investigators, and the funder were masked to treatment allocation. Endpoints assessed in the intention-to-treat population were change from baseline in clinic trough FEV1 at week 24 (primary) and annualised moderate and/or severe asthma exacerbation rate (key secondary). Other secondary endpoints were change from baseline in clinic FEV1 at 3 h post-dose, St George's Respiratory Questionnaire (SGRQ) total score, and ACQ-7 total score, all at week 24. Change from baseline in Evaluating Respiratory Symptoms in Asthma total score at weeks 21-24 was also a secondary endpoint but is not reported here. Exploratory analyses of biomarkers of type 2 airway inflammation on treatment response were also done. This study is registered with ClinicalTrials.gov, NCT02924688, and is now complete. FINDINGS Between Dec 16, 2016, and Aug 31, 2018, 5185 patients were screened and 2439 were recruited and randomly assigned to FF/VI (100/25 μg n=407; 200/25 μg n=406) or FF/UMEC/VI (100/31·25/25 μg n=405; 100/62·5/25 μg n=406; 200/31·25/25 μg n=404; 200/62·5/25 μg n=408), with three patients randomly assigned in error and not included in analyses. In the intention-to-treat population, 922 (38%) patients were men, the mean age was 53·2 years (SD 13·1) and body-mass index was 29·4 (6·6). Baseline demographics were generally similar across all treatment groups. The least squares mean improvement in FEV1 change from baseline for FF/UMEC/VI 100/62·5/25 μg versus FF/VI 100/25 μg was 110 mL (95% CI 66-153; p<0·0001) and for 200/62·5/25 μg versus 200/25 μg was 92 mL (49-135; p<0·0001). Adding UMEC 31·25 μg to FF/VI produced similar improvements (FF/UMEC/VI 100/31·25/25 μg vs FF/VI 100/25 μg: 96 mL [52-139; p<0·0001]; and 200/31·25/25 μg vs 200/25 μg: 82 mL [39-125; p=0·0002]). These results were supported by the analysis of clinic FEV1 at 3 h post-dose. Non-significant reductions in moderate and/or severe exacerbation rates were observed for FF/UMEC 62·5 μg/VI versus FF/VI (pooled analysis), with rates lower in FF 200 μg-containing versus FF 100 μg-containing treatment groups. All pooled treatment groups demonstrated mean improvements (decreases) in SGRQ total score at week 24 compared with baseline in excess of the minimal clinically important difference of 4 points; however, there were no differences between treatment groups. For mean change from baseline to week 24 in asthma control questionnaire-7 score, improvements (decreases) exceeding the minimal clinically important difference of 0·5 points were observed in all pooled treatment groups. Adding UMEC to FF/VI resulted in small, dose-related improvements compared with FF/VI (pooled analysis: FF/UMEC 31·25 μg/VI versus FF/VI, -0·06 (95% CI -0·12 to 0·01; p=0·094) FF/UMEC 62·5 μg/VI versus FF/VI, -0·09 (-0·16 to -0·02, p=0·0084). By contrast with adding UMEC, the effects of higher dose FF on clinic trough FEV1 and annualised moderate and/or severe exacerbation rate were increased in patients with higher baseline blood eosinophil count and exhaled nitric oxide. Occurrence of adverse events was similar across treatment groups (patients with at least one event ranged from 210 [52%] to 258 [63%]), with the most commonly reported adverse events being nasopharyngitis (51 [13%]-63 [15%]), headache (19 [5%]-36 [9%]), and upper respiratory tract infection (13 [3%]-24 [6%]). The incidence of serious adverse events was similar across all groups (range 18 [4%]-25 [6%)). Three deaths occurred, of which one was considered to be related to study drug (pulmonary embolism in a patient in the FF/UMEC/VI 100/31·25/25 μg group). INTERPRETATION In patients with uncontrolled moderate or severe asthma on ICS/LABA, adding UMEC improved lung function but did not lead to a significant reduction in moderate and/or severe exacerbations. For such patients, single-inhaler FF/UMEC/VI is an effective treatment option with a favourable risk-benefit profile. Higher dose FF primarily reduced the rate of exacerbations, particularly in patients with raised biomarkers of type 2 airway inflammation. Further confirmatory studies into the differentiating effect of type 2 inflammatory biomarkers on treatment outcomes in asthma are required to build on these exploratory findings and further guide clinical practice.

Abstract
BACKGROUND Approximately 5-10% of patients with asthma have severe disease. High-quality real-world studies are needed to identify areas for improved management. OBJECTIVE Aligned with the International Severe Asthma Registry, the CHRONICLE study (ClinicalTrials.gov: NCT03373045) was developed to address this need in the US. STUDY DESIGN Learnings from prior studies were applied to develop a real-world, prospective, noninterventional study of US patients with confirmed severe asthma who are treated by subspecialist physicians and require biologic or maintenance systemic immunosuppressant therapy or who are uncontrolled by high-dosage inhaled corticosteroids and additional controllers. Target enrollment is 4000 patients, with patient observation for ≥3 years. A geographically diverse sample of allergist/immunologist and pulmonologist sites approach all eligible patients under their care and report patient characteristics, treatment, and health outcomes every 6 months. Patients complete online surveys every 1-6 months. INITIAL RESULTS From February 2018 to February 2019, 102 sites screened 1428 eligible patients; 936 patients enrolled. Study sites (40% allergist/immunologist, 42% pulmonologist, 18% both) were similar to other US asthma subspecialist samples. Enrolled patients were 67% female with median ages at enrollment and diagnosis of 55 (range: 18-89) and 26 (0-80) years, respectively. Median body mass index was 31 kg/m2; 3% and 29% were current or former smokers, respectively, and >60% reported ≥1 exacerbation in the prior year and suboptimal symptom control. CONCLUSION CHRONICLE will provide high-quality provider- and patient-reported data from a large, real-world cohort of US adults with subspecialist-treated severe asthma.

Abstract
OBJECTIVE Asthma, a major cause of disability and reduced quality of life, has a high global prevalence and burden of death. Despite the propitious guidelines, a substantial portion of asthmatics reportedly have poorly controlled disease. In the current study, we have examined risk factors for uncontrolled asthma in specialty clinics and its association with impaired quality of life. METHODS A multicentre cross-sectional survey of asthma patients, 18 years and older, was conducted in Trinidad. Asthma Control Test (ACT) and the Juniper Mini Asthma Quality of Life Questionnaire (Mini AQLQ-J) were used to assess the disease control and quality of life, respectively. Data were analyzed using the Chi-square test and multivariable logistic regression controlling for gender. RESULTS Of a total of 428 patients included, asthma was uncontrolled in 72.4% and asthma related quality of life was moderate to severely impaired in 86% of the studied population. In the multivariate regression models, poorly controlled asthma was associated with obesity (OR 2.25; 95% CI 1.30-3.39), late-onset asthma (OR 1.72; 95% CI 1.04-2.84), features of sleep apnea (OR 1.77; 95% CI 1.01-3.07) and depression (OR 2.01; 95% CI 1.04-3.86). Impaired quality of life was associated with Indo-Caribbean ethnicity (OR 3.19; 95% CI = 1.68-6.06). CONCLUSIONS In this Caribbean population, uncontrolled asthma was independently associated with obesity, late-onset disease, and comorbidities of sleep apnea and depression. Poor asthma-related quality of life was independently associated with Indo-Caribbean ethnicity.

Abstract
OBJECTIVES Biologic therapies are emerging as an option to treat a subset of patients with severe asthma, however no direct comparison between these agents has been conducted. Furthermore, heterogeneity of outcomes in clinical trials makes it difficult to compare these agents and traditional therapies. The extent to which this heterogeneity exists has major implications for evidence-based decisions and is yet to be fully reported. We conducted a literature search to examine outcomes currently being used in clinical trials for asthma. DATA SOURCES The Cochrane Library and Clinicaltrials.gov were searched for clinical trials of asthma interventions. STUDY SELECTIONS We limited our search to phase 2 through 4 clinical trials in adults, as early-phase trials tend to have pharmacodynamic and pharmacokinetic endpoints as primary outcomes. Interventions for acute exacerbations were excluded. RESULTS We identified 117 studies and subsequently identified 111 outcomes. The most prevalent outcomes were asthma control and symptom severity, FEV1, and change in ACQ scale. Twenty patient-reported outcomes instruments were identified and de-facto standard asthma outcomes and PROs were under-reported in examined literature. Existing quality of life tools did not capture the day-to-day experience or the unique treatment burden from oral corticosteroids for patient with severe asthma. Compounding the absence of trials directly comparing therapies, the significant variation we identified in outcome definitions and measurement create hurdles to effectively compare traditional and biologic therapies. CONCLUSION With the growing number of clinical trials evaluating advanced therapies such as biologics, a wide range of primary and secondary outcomes are evaluated. A core outcome set created by relevant stakeholders is needed to collectively evaluate pooled outcomes in order to allow more meaningful comparisons of asthma therapies and to incorporate the patient experience.

Abstract
Rationale: Despite effective treatments, a large proportion of patients with asthma do not achieve sustained asthma control. The “preventable” burden associated with lack of proper control is likely taking a high toll at the personal and population level. Objectives: We predicted the future excess health and economic burden associated with uncontrolled asthma among American adolescents and adults for the next 20 years. Methods: We built a probabilistic model that linked state-specific estimates of population growth, aging, asthma prevalence, and asthma control levels. We conducted several meta-analyses to estimate the adjusted differences in healthcare resource use, quality-adjusted life years (QALYs), and productivity loss across control levels. We projected, nationally and at the state level, total direct and indirect (due to productivity loss) costs (in 2018 dollars) and QALYs lost because of uncontrolled asthma from 2019 to 2038. Measurements and Main Results: Total 20-year direct costs associated with uncontrolled asthma are estimated to be $300.6 billion (95% confidence interval [CI], $190.1 billion–411.1 billion). When indirect costs are added, total economic burden will be $963.5 billion (95% CI, $664.1 billion–1,262.9 billion). American adolescents and adults will lose an estimated 15.46 million (95% CI, 12.77 million–18.14 million) QALYs over this period because of uncontrolled asthma. Across states, the average 20-year per capita costs due to uncontrolled asthma ranged from $2,209 (Arkansas) to $6,132 (Connecticut). Conclusions: The burden of uncontrolled asthma is substantial and will continue to grow. Given that a substantial fraction of this burden is preventable, better adherence to evidence-informed asthma management strategies by care providers and patients has the potential to substantially reduce costs and improve quality of life.

Abstract
OBJECTIVES Severe asthma (SA) can be uncontrolled despite guideline-directed treatment. We described SA characteristics and identified factors associated with uncontrolled disease and frequent exacerbations. METHODS Post hoc analysis of the observational IDEAL study (201722/NCT02293265) included patients with SA aged ≥12 years receiving high-dose inhaled corticosteroids plus additional controller(s) for ≥12 months. Uncontrolled SA was defined by Asthma Control Questionnaire (ACQ)-5 scores ≥1.5 or ≥1 exacerbations (prior year), and further stratified by exacerbation frequency (no/infrequent [0-1] vs frequent [≥2]; prior year); associated factors were determined using multivariate logistic regression. RESULTS Of 670 patients with SA, 540 (81%) were uncontrolled (ACQ-5 scores ≥1.5: 80%; ≥1 exacerbations [prior year]: 71%). Uncontrolled patients had lower lung function and worse health-related quality of life (HRQoL) than controlled patients; 197/540 (37%) experienced frequent exacerbations (prior year). Worse St George's Respiratory Questionnaire (SGRQ) total score, comorbid sinusitis, or eczema were significantly associated with uncontrolled SA; younger age, never smoker status, exacerbation requiring hospitalization (previous year), worse SGRQ symptom score, comorbid nasal polyps, COPD, or osteoporosis were significantly associated with uncontrolled SA with frequent exacerbations. CONCLUSIONS In IDEAL, one-fifth of patients with SA were controlled, based on symptoms. Uncontrolled, exacerbating SA was associated with specific comorbidities, frequent exacerbations, a lower lung function, and compromised HRQoL, although inference from this analysis is limited by the selective cross-sectional nature of the cohort. Nonetheless, these data highlight the need for more effective precision treatments in this population.

Abstract
Asthma is a chronic disease affecting more than 300 million people globally. Poor asthma control that leads to unnecessary symptoms is estimated to affect nearly half of people with asthma. A critical way to address poor control is for healthcare professionals (HCPs) and patients to enter a shared dialogue on treatment and asthma management. This article explores the views of both patient and HCP to better understand how to achieve asthma control. From the patient's perspective, being a person with asthma has ramifications to one's sense of identity, and thus one's ability and willingness to actively manage their asthma. Furthermore, lack of education and concerns about the effectiveness of treatment can also ultimately lead to poor control, a term that can be understood differently by patients and HCPs. One goal is to help to normalise life for people with asthma. For this, HCPs need to align on what this means for each individual and then work together to produce a plan that can be applied to the patient's daily life. Training for HCPs on good communication skills and empowering patients to be involved in their asthma management are both critical to ensure effective shared decision-making and, ultimately, improved quality of life for people with asthma.

Abstract
Background: Uncontrolled asthma (BA) can be complicated by cardiac conduction disturbances and arrhythmias. It is typical mainly for adult asthmatics patients. In asthmatics children the effect of bronchoconstriction on cardiac conduction, including the supraventricular component of the ECG, is currently under discussion. The objective of the research is to analyze ECG parameters of the atrial complex and atrioventricular conduction and to assess their relationship with spirometric indicators in children with BA. Methods: Hundred three patients with BA from the age of 6-17 years were examined. The spirometric parameters were evaluated, including the Tiffeneau index (TI): FEV1/FVC (%), according to the level of which the patient groups were distinguished. Group 1 (G1): with TI more than 85%, (n = 15); Group 2 (G2): with TI from 85 to 75%, (n = 40); Group 3 (G3): with TI <75%, (n = 48). The ECG parameters that characterize supraventricular conduction, including the PQ interval (sec) and the sPQ segment (sec), were analyzed. We had calculated relative PQ (rPQ) by the formula rPQ=PQ/PQmed, where PQ is the patient's PQ, PQmed are the median PQ values of healthy children of age selected. Results: The duration of the PQ in groups G1 and G2 was 0.13 (0.11; 0.14) s; and 0.13 (0.12; 0.14) s, respectively, which is statistically significantly less than in patients of groups G3-0.14 (0.13; 0.15] s, p = 0.01. The duration of the sPQ segment in children of groups G1 and G2 was also generally shorter than in patients of groups G3, and amounted, respectively, to 0.05 (0.04; 0.06) s, 0.04 (0.04; 0.05) s, and 0.06 (0.04; 0.07) s, p = 0.02. The rPQ increased progressively as TI decreased and amounted in G1 to 92.9 (85.7; 106.3) %, in G2 100.0 (92.9; 103.0) %, and in G3 104 (100.0; 107.7) %, p = 0.009. A statistically significant negative correlation between IT and PQ-r = -0.23, p = 0.02; with sPQ-r = -0.20, p = 0.045; and with rPQ-r = -0.25, p = 0.01 was revealed. Conclusion: A decrease in TI in asthmatics children is associated with a prolongation of the PQ. This may indicate a slowdown in supraventricular conduction in patients with uncontrolled asthma and, thus, be considered as a risk for the formation of subsequent supraventricular arrhythmias.

Abstract
Tiotropium Respimat is an efficacious add-on to maintenance treatment in patients with symptomatic asthma. Currently, the Global Initiative for Asthma (GINA) strategy recommends tiotropium for patients at Steps 4-5. To assess the clinical benefits of tiotropium Respimat across asthma severities, GINA Steps 2-5, a post hoc analysis of five double-blind trials (12-48-weeks; patients aged 18-75 years) investigated the effect of tiotropium Respimat, 5 μg or 2.5 μg, versus placebo, on peak forced expiratory volume in 1 s (FEV1) within 3 h post-dose (FEV1(0-3h)) response, and Asthma Control Questionnaire-7 (ACQ-7) responder rate. GINA step grouping was based on patients' background treatment regimen. Baseline characteristics of patients (N = 2926) were balanced between treatments. Tiotropium Respimat showed consistent improvements in lung function across GINA steps; placebo-corrected peak FEV1(0-3h) improvements after tiotropium Respimat 5 μg and 2.5 μg were: Step 2 (Week 8), 135 mL (95% confidence interval: 84, 187) and 155 mL (103, 206); Step 3 (Week 24), 187 mL (139, 235) and 235 mL (187, 283); Step 4 (Week 24), 111 mL (63, 159) and 181 mL (35, 326); Step 5 (Week 24; 5 μg only), 164 mL (5, 323). Asthma control improved with tiotropium Respimat versus placebo, showing statistical significance (nominal P value) with tiotropium Respimat 5 μg at Step 4 (odds ratio 1.36 [1.03, 1.78]). Safety profiles were similar between treatments. In conclusion, tiotropium Respimat add-on therapy improves lung function, and may improve asthma control, in adults across disease severities.

Abstract
BACKGROUND Asthma diagnosis in the community is often made without objective testing. OBJECTIVE The aim of this study was to evaluate the cost-effectiveness of implementing a stepwise objective diagnostic verification algorithm among patients with community-diagnosed asthma in the United States. METHODS We developed a probabilistic time-in-state cohort model that compared a stepwise asthma verification algorithm on the basis of spirometry testing and a methacholine challenge test against the current standard of care over 20 years. Model input parameters were informed from the literature and with original data analyses when required. The target population was US adults (≥15 years old) with physician-diagnosed asthma. The final outcomes were costs (in 2018 dollars) and quality-adjusted life years (QALYs), discounted at 3% annually. Deterministic and probabilistic analyses were undertaken to examine the effect of alternative assumptions and uncertainty in model parameters on the results. RESULTS In a simulated cohort of 10,000 adults with diagnosed asthma, the stepwise algorithm resulted in removal of the diagnosis of 3,366. This was projected to be associated with savings of $36.26 million in direct costs and a gain of 4,049.28 QALYs over 20 years. Extrapolating these results to the US population indicated an undiscounted potential savings of $56.48 billion over 20 years. The results were robust against alternative assumptions and plausible changes in values of input parameters. CONCLUSION Implementation of a simple diagnostic testing algorithm to verify asthma diagnosis might result in substantial savings and improvement in patients' quality of life.

Abstract
Objective: To estimate the health-related quality of life (HRQoL) and health utilities among asthma patients with and without comorbid allergies in a managed care population.Methods: This was a retrospective analysis of patient survey responses and pharmacy claims from the Observational Study of Asthma Control and Outcomes (OSACO). Patients ≥12 years-old with persistent asthma received four identical surveys between April-2011 and December-2012. The presence of allergy was identified by a positive response to a survey question about hay fever/seasonal allergies and ≥1 diagnosis-related ICD-9-CM code(s) for allergic conditions. HRQoL instruments included generic utility (EQ-5D-3L [including VAS]), asthma-specific utility (AQL-5D) and asthma-specific health status (Mini Asthma Quality of Life Questionnaire [MiniAQLQ]). Median regression was used for utility scores and Least Squares regression for MiniAQLQ, adjusting for sociodemographic characteristics and smoking.Results: Of the 2681 asthmatics who completed the first survey in the OSACO study, 971 had comorbid allergies. After adjusting for covariates, asthma patients with comorbid allergies had significantly lower MiniAQLQ scores than patients without allergies (-0.489 [95% CI -0.570, -0.409]; p < 0.01), with the greatest decrement/impairment observed for the environmental stimuli domain (-0.729 [95% CI -0.844, -0.613]; p < 0.01). Utility scores were also statistically significantly lower for asthma patients with comorbid allergies compared to those without allergies (EQ-5D, -0.031 [95% CI -0.047, -0.015]; AQL-5D, -0.036 [95% CI -0.042, -0.029]; p < 0.01 each).Conclusions: The presence of allergies with persistent asthma is associated with a significant deleterious impact on several different measures of HRQoL.

Abstract
Objective: To compare healthcare resource utilization (HCRU), healthcare expenditures, and work productivity and activity impairment within a general asthma population with persistent asthma and evidence of allergy (PA-EA) and persistent asthma with no evidence of allergy (PA-NEA).Methods: We conducted a retrospective analysis of survey responses and claims from the Observational Study of Asthma Control and Outcomes (OSACO) study. Eligible patients with persistent asthma aged ≥12 years were sent four surveys over 15 months. Regression models were used to assess the association between: (1) PA-EA (defined as a positive response to a survey question about hay fever/seasonal allergies AND ≥1 diagnostic code for atopic conditions) and HCRU and expenditures; and (2) PA-EA and Work Productivity and Activity Impairment (WPAI)-Asthma questionnaire scores (vs. PA-NEA).Results: Adjusted data showed that, vs. PA-NEA (n = 312), patients with PA-EA (n = 971) incurred 1.34-times more all-cause prescriptions (95% confidence interval [CI], 1.20-1.48), $132.79 higher prescription costs (95% CI, $22.03-243.56), and $926.11 higher all-cause total healthcare costs (95% CI, $279.67-1572.54), per 4-month period. Patients with PA-EA were 4.1% less productive while working (95% CI, 3.75-4.48%) and experienced a 6.5% reduction in all activities (95% CI, 6.11-6.88%) vs. those with PA-NEA.Conclusions: Patients with PA-EA had greater HCRU, healthcare expenditures, and lower productivity compared with those patients with PA-NEA. These results highlight the burden of atopy in patients with persistent asthma and underscore the importance of allergic endotype identification for more vigilant disease management.
