Background: Benralizumab has been reported to lead to clinical remission of severe eosinophilic asthma (SEA) at 1 year in some patients. However, whether this is maintained over a longer term remains unclear. Additionally, the impact of pulmonary and extrapulmonary comorbidities on the ability to meet remission is poorly understood. Methods: Clinical outcomes including remission of SEA with benralizumab at 1 and 2 years were assessed retrospectively in a real‐world UK multi‐centre severe asthma cohort. The presence of clinically relevant pulmonary and extrapulmonary comorbidities associated with respiratory symptoms was recorded. Analyses to identify factors associated with the ability to meet remission were performed. Results: In total, 276 patients with SEA treated with benralizumab including 113 patients who had switched from a previous biologic to benralizumab were included. Overall, clinical remission was met in 17% (n = 31/186) and 32% (n = 43/133) of patients at 1 and 2 years, respectively. This increased to 28% at 1 year and 49% at 2 years once patients with pulmonary and/or extrapulmonary comorbidities were excluded. Body mass index (BMI) and maintenance OCS (mOCS) use demonstrated a negative association with clinical remission at 1 (BMI: OR: 0.89, 95% CI: 0.82–0.96, p < 0.01; mOCS: OR: 0.94, 95% CI: 0.89–0.99, p < 0.05) and 2 years (BMI: OR: 0.93, 95% CI: 0.87–0.99, p < 0.05; mOCS: OR: 0.95, 95% CI: 0.89–0.99, p < 0.05). Conclusions: In this long‐term, real‐world study, patients with SEA demonstrated the ability to meet and sustain clinical remission when treated with benralizumab. The presence of comorbidities including obesity, which are known to be independently associated with respiratory symptoms, reduced the likelihood of meeting clinical remission.

Introduction: One of the fundamental challenges of managing patients with severe asthma is treatment adherence, particularly with inhaled corticosteroids. Adherence is difficult to measure objectively and poor adherence is associated with worse outcomes. In this study, assess the ability of a 'smart' inhaler to record adherence in severe asthma patients and measure the impact of this on asthma control. Methods: Consecutive consenting patients meeting criteria for biologics had their existing high-dose ICS/LABA//LAMA combination inhaler/s switched to mometasone/indacaterol/glycopyrronium (114/46/136). Routine clinical data, including blood eosinophils, FeNO, and ACQ-6 scores were collected at baseline and at 4 wk. Adherence was then checked on the Propeller Health app, and good adherence was defined as >80% of prescribed usage. Participants were then followed-up at 12 months to record the proportion of patients who were initiated on biologics Results: 77 patients (mean [SD] age = 50.4 [15.7] years, 67.5% female [n = 52]) participated. 71 participants were able to use the device and 65% (n = 46) of these attained good asthma control and were not initiated on biologics at 12-month follow-up. Both groups demonstrated a significant reduction in ACQ6 score at follow-up (2.81 vs. 1.92, p < 0.001 and 3.05 vs. 2.60, p < 0.001, respectively), but there was no statistically significant difference in improvement between groups. Patients with optimal adherence also demonstrated a significant reduction in median FeNO at follow-up (47 ppb vs. 40 ppb, p = 0.003). Conclusions: In severe asthma patients, 'smart' inhalers may represent an effective management tool to improve adherence and asthma control, therefore avoiding the need for patients to commence biological therapies.

Cough is an important symptom of asthma. The objective assessment of chronic cough has been enhanced by the development of ambulatory cough monitoring systems. Mepolizumab has been demonstrated to reduce exacerbations in eosinophilic asthmatics long-term. We evaluate the utility of objective cough count as an outcome measure in severe eosinophilic asthma treated with mepolizumab. Consecutive, consenting patients initiated on treatment with mepolizumab had a 24-h cough count recorded at baseline; this was repeated at 1, 3 and 6 months. Asthma control questionnaire (ACQ) scores and exacerbation frequency were also recorded. The mean 24-h cough count in 11 subjects (8 females, mean age 53.6 years) was 172.4 at baseline; at 1, 3 and 6 months following initiation of treatment this decreased to 101.4, 92 and 70.8, respectively (p < 0.02). Significant improvements were also observed in mean ACQ score (3-1.6, p < 0.01) and exacerbation frequency (5.5 per year - 1.3, p < 0.01). Objective cough measurement could be used as an early, precise and clinically relevant endpoint in assessing response to asthma therapy., Author(s): Shoaib Faruqi [sup.1], Dominic L.

Background: The Asthma Control Questionnaire (ACQ) is used to assess asthma symptom control. The relationship between the questionnaire items and symptom control has not been fully studied in severe asthmatic patients, and its validity for making comparisons between subgroups of patients is unknown. Methods: Data was obtained from patients in the United Kingdom Severe Asthma Registry whose symptom control was assessed using the five-item ACQ (ACQ5) (n = 2,951). Confirmatory factor analysis determined whether a latent factor for asthma symptom control, as measured by the ACQ5, was consistent with the data. Measurement invariance was examined in relation to ethnicity, sex and age; this included testing for approximate measurement invariance using Bayesian Structural Equation Modelling (BSEM). The fitted models were used to estimate the internal consistency reliability of the ACQ5. Invariance of factor means across subgroups was assessed. Results: A one-factor construct with residual correlations for the ACQ5 was an excellent fit to the data in all subgroups (Root Mean Square Error Approximation 0.03 [90%CI 0.02,0.05], p-close fit 0.93, Comparative Fit Index 1.00, Tucker Lewis Index 1.00}. Expected item responses were consistent for Caucasian and non-Caucasian patients with the same absolute level of symptom control. There was some evidence that females and younger adults reported wakening more frequently during the night than males and older adults respectively with the same absolute level of symptom control (p<0.001). However approximate measurement invariance was tenable and any failure to observe strong measurement invariance had minimal impact when comparing mean levels of asthma symptom control between patients of different sexes or ages. Average levels of asthma symptom control were lower for non-Caucasians (p = 0.001), females (p<0.01)and increased with age (p<0.01). Reliability of the instrument was high (over 88%) in all subgroups studied. Conclusion: The ACQ5 is informative in comparing levels of symptom control between severe asthmatic patients of different ethnicities, sexes and ages. It is important that analyses are replicated in other severe asthma registries to determine whether measurement invariance is observed. [ABSTRACT FROM AUTHOR]
