Abstract
BACKGROUND Oral corticosteroid (OCS) dependence among patients with severe eosinophilic asthma can cause adverse outcomes, including adrenal insufficiency. PONENTE's OCS reduction phase showed that, following benralizumab initiation, 91.5% of patients eliminated corticosteroids or achieved a final dosage ≤5 mg·day-1 (median (range) 0.0 (0.0-40.0) mg). METHODS The maintenance phase assessed the durability of corticosteroid reduction and further adrenal function recovery. For ∼6 months, patients continued benralizumab 30 mg every 8 weeks without corticosteroids or with the final dosage achieved during the reduction phase. Investigators could prescribe corticosteroids for asthma exacerbations or increase daily dosages for asthma control deteriorations. Outcomes included changes in daily OCS dosage, Asthma Control Questionnaire (ACQ)-6 and St George's Respiratory Questionnaire (SGRQ), as well as adrenal status, asthma exacerbations and adverse events. RESULTS 598 patients entered PONENTE; 563 (94.1%) completed the reduction phase and entered the maintenance phase. From the end of reduction to the end of maintenance, the median (range) OCS dosage was unchanged (0.0 (0.0-40.0) mg), 3.2% (n=18/563) of patients experienced daily dosage increases, the mean ACQ-6 score decreased from 1.26 to 1.18 and 84.5% (n=476/563) of patients were exacerbation free. The mean SGRQ improvement (-19.65 points) from baseline to the end of maintenance indicated substantial quality-of-life improvements. Of patients entering the maintenance phase with adrenal insufficiency, 32.4% (n=104/321) demonstrated an improvement in adrenal function. Adverse events were consistent with previous reports. CONCLUSIONS Most patients successfully maintained maximal OCS reduction while achieving improved asthma control with few exacerbations and maintaining or recovering adrenal function.

Abstract
BACKGROUND No consensus exists on how to reduce oral corticosteroids after the initiation of biologics in severe asthma. The PONENTE trial evaluated the effectiveness and safety of a rapid, individualised steroid-reduction algorithm, including adrenal insufficiency monitoring, after benralizumab initiation. METHODS This multicentre, open-label, single-arm study was done at 138 clinical asthma treatment centres across 17 countries. We enrolled adult patients (age ≥18 years) with severe, eosinophilic asthma (blood eosinophil count ≥150 cells per μL at enrolment or ≥300 cells per μL in the previous year) requiring maintenance oral corticosteroids for at least 3 months preceding enrolment. Patients received benralizumab 30 mg (subcutaneous injection) every 4 weeks for three doses, then every 8 weeks thereafter. The oral corticosteroid reduction phase began at week 4 with daily oral corticosteroid dosages reduced by 1-5 mg every 1-4 weeks depending on the starting dosage, asthma control, and adrenal function status. Adrenal function was assessed with an early morning serum cortisol measurement, followed by adrenocorticotropic hormone stimulation when required, once patients achieved a daily oral corticosteroid dosage of 5 mg/day for 4 weeks. Repeat cortisol measurements were taken for patients with evidence of adrenal insufficiency at first testing. Asthma control was assessed with the Asthma Control Questionnaire-6 (ACQ-6) weekly throughout the induction and oral corticosteroid reduction phases. The primary endpoints were the percentage of patients eliminating daily oral corticosteroids, sustained for at least 4 weeks, and the percentage achieving elimination or a daily prednisone or prednisolone dosage of 5 mg or less, for at least 4 weeks, if the reason for no further reduction was adrenal insufficiency. Safety and efficacy analyses included all patients who received at least one dose of benralizumab and were descriptive. We present results after the oral corticosteroid reduction phase; a maintenance phase is ongoing. The trial is registered with ClinicalTrials.gov, NCT03557307. FINDINGS Between April 1, 2018, and Sept 5, 2020, of 705 patients assessed for eligibility, 598 were recruited and all received at least one dose of benralizumab. Overall, 376 (62·88%, 95% CI 58·86-66·76) of 598 patients eliminated oral corticosteroids and 490 (81·94%, 78·62-84·94) of 598 eliminated use or achieved a dosage of 5 mg or less if the reason for stopping the reduction was adrenal insufficiency. Subgroup analysis showed that dosage reductions were achieved irrespective of baseline eosinophil count, baseline oral corticosteroid dosage, or oral corticosteroid treatment duration. Adrenal insufficiency was detected in 321 (60%) of 533 patients at first assessment and in 205 (38%) of 533 patients 2-3 months later. The safety profile was consistent with previous experience. Most patients (448 [75%] of 598) had no asthma exacerbations during the oral corticosteroid reduction phase with an annualised exacerbation rate of 0·63. Of 598 patients, 38 (6%) experienced a total of 46 exacerbations resulting in emergency department or urgent care visits or hospitalisations. INTERPRETATION Despite a high prevalence of adrenal insufficiency, most patients with eosinophilic asthma treated with benralizumab achieved elimination of oral corticosteroids or maximal possible reduction using a personalised dosage-reduction algorithm.

Abstract
BACKGROUND Studies of asthma and chronic obstructive pulmonary disease (COPD) typically focus on these diagnoses separately, limiting understanding of disease mechanisms and treatment options. NOVELTY is a global, 3-year, prospective observational study of patients with asthma and/or COPD from real-world clinical practice. We investigated heterogeneity and overlap by diagnosis and severity in this cohort. METHODS Patients with physician-assigned asthma, COPD or both (asthma+COPD) were enrolled, and stratified by diagnosis and severity. Baseline characteristics were reported descriptively by physician-assigned diagnosis and/or severity. Factors associated with physician-assessed severity were evaluated using ordinal logistic regression analysis. RESULTS Of 11 243 patients, 5940 (52.8%) had physician-assigned asthma, 1396 (12.4%) had asthma+COPD and 3907 (34.8%) had COPD; almost half were from primary care. Symptoms, health-related quality of life and spirometry showed substantial heterogeneity and overlap between asthma, asthma+COPD and COPD, with 23%, 62% and 64% of patients, respectively, having a ratio of post-bronchodilator forced expiratory volume in 1 s to forced vital capacity below the lower limit of normal. Symptoms and exacerbations increased with greater physician-assessed severity and were higher in asthma+COPD. However, 24.3% with mild asthma and 20.4% with mild COPD had experienced ≥1 exacerbation in the past 12 months. Medication records suggested both under-treatment and over-treatment relative to severity. Blood eosinophil counts varied little across diagnosis and severity groups, but blood neutrophil counts increased with severity across all diagnoses. CONCLUSION This analysis demonstrates marked heterogeneity within, and overlap between, physician-assigned diagnosis and severity groups in patients with asthma and/or COPD. Current diagnostic and severity classifications in clinical practice poorly differentiate between clinical phenotypes that may have specific risks and treatment implications.
