Many questions concerning responders (R) and nonresponders (NR) in severe eosinophilic asthma (SEA) after blocking the IL-5 (interleukin 5) pathway are still not clear, especially regarding the early parameters of response to biologics in personalized treatment strategies. We evaluated 17 SEA patients treated with anti-IL-5 biologics (16 patients mepolizumab, one patient benralizumab) before the introduction of biologics, and at a week 16 follow-up. Clinical, cellular and immunological parameters in peripheral blood were measured in R and NR. Sputum induction with the measurement of cellular and immunological parameters was performed at 16 weeks only. There were 12 R and 5 NR to biologics. After 16 weeks, there was a significant improvement in percentages of FEV1 (p = 0.001), and asthma control test (ACT) (p = 0.001) in the R group, but not in NR. After 16 weeks, the eosinophils in induced sputum were 27.0% in NR and 4.5% in R (p = 0.05), with no difference in IL-5 concentrations (p = 0.743). Peripheral eosinophilia decreased significantly in NR (p = 0.032) and R (p = 0.002). In patients with SEA on anti-IL-5 therapy, there was a marked difference in airway eosinophilic inflammation between R and NR already at 16 weeks, after anti-IL-5 introduction.

Reslizumab, an anti-interleukin-5 monoclonal antibody, significantly reduces exacerbation frequency and improves lung function, asthma control and quality of life in adults with severe eosinophilic asthma, as demonstrated in Phase III studies.This secondary analysis assessed reslizumab's efficacy in patients receiving baseline treatment per Global Initiative for Asthma (GINA) Step 4 and Step 5 guidelines.Pooled data from duplicate, Phase III, reslizumab versus placebo studies in patients with severe eosinophilic asthma (blood eosinophils ≥400 cells·µL−1) were stratified by baseline therapy. Efficacy assessments were exacerbation rates and changes from baseline forced expiratory volume in 1 s (FEV1) and patient-reported outcomes.Of 953 patients, 69% (n=657) and 11% (n=106) were receiving Step 4 and Step 5 therapy, respectively. Compared with placebo, reslizumab reduced exacerbation rates by 53% (95% CI 0.36–0.62) and 72% (95% CI 0.15–0.52), in Step 4 and Step 5 groups respectively. By study end, reslizumab increased FEV1 in Step 4 and Step 5 groups by 103 mL (95% CI 52–154 mL) and 237 mL (95% CI 68–407 mL), respectively. Reslizumab also improved patient-reported outcomes compared with placebo in both groups.Reslizumab reduces exacerbation rates and improves lung function and patient-reported outcomes in patients with eosinophilic asthma receiving therapy per Steps 4 and 5 of the GINA guidelines.

The Difference

Abstract Background Benralizumab, a monoclonal antibody targeting the human interleukin-5 (IL-5) receptor (IL-5R), was used before marketing authorisation in Spain in a real world setting as part of an early-access programme (EAP) to treat patients with severe eosinophilic asthma with prior insufficient response or intolerance to anti-IL5 treatment (mepolizumab or reslizumab). The objective of this study is to describe the patient profile candidate for treatment and to assess benralizumab effectiveness. Methods This is an observational, retrospective, multicentre study in severe eosinophilic asthma patients refractory to other biological agents targeting the IL-5 pathway. Baseline characteristics included closest data, from the previous 12 months, to benralizumab treatment onset (index date). Patients were followed until the last treatment dosage while EAP was active (March to December 2018). Effectiveness was evaluated versus baseline, in patients who received at least three doses, with asthma control test (ACT), Mini Asthma Quality of Life Questionnaire (MiniAQLQ), annual severe exacerbation rate, oral corticosteroids treatment (OCS) and asthma-related healthcare resources utilization. Results Twenty-seven patients treated with benralizumab were included in the analysis. Effectiveness was assessed in 19 patients. Both questionnaires showed clinically meaningful differences, i.e. ACT score ≥ 3 and MiniAQLQ score ≥ 0.5, compared with baseline [mean (SD), 3.3 (6.8) and 1.2 (1.9), respectively]. Patients treated with OCS decreased during follow-up from 88.9% (n = 24/27) at baseline to 78.9% (n = 15/19) and 31.6% (n = 6/19) had an OCS dose reduction ≥ 50%. The difference in annual severe exacerbation rate during follow-up showed a significant reduction vs. baseline (2.12 per patient-year, 95% CI 0.99–3.24, p = 0.002). The differences in annual rate of non-scheduled primary care and specialist visits during follow-up indicated a significant decrease [2.28 per patient-year (95% CI 1.55–3.01; p < 0.001) and 1.47 per patient-year (95% CI 0.65–2.30; p = 0.004), respectively], as well as the difference in annual rate of number of emergency department visits [1.18 per patient-year (95% CI 0.51–1.85; p = 0.007)]. Conclusions These results suggest that severe eosinophilic asthma patients receiving benralizumab, presented clinically meaningful improvement in asthma control and asthma-related QoL as well as OCS dose reduction. Results also aim to significant reductions in annual severe exacerbation rates, non-scheduled primary care and specialist visits, and emergency department visits rates.

AbstractSevere asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS), which worsen patients’ health and increase healthcare spending. The aim of this study was to assess the clinical and economic impact of switching from omalizumab (OMA) to mepolizumab (MEP) in patients eligible for both biologics, but not optimally controlled by omalizumab. We retrospectively enrolled uncontrolled severe asthmatic patients who switched from OMA to MEP during the last two years. Information included blood eosinophil count, asthma control test (ACT), spirometry, serum IgE, fractional exhaled nitric oxide (FeNO), OCS intake, drugs, exacerbations/hospitalizations, visits and diagnostic exams. Within the perspective of Italian National Health System, a pre- and post-MEP 12-month standardized total cost per patient was calculated. 33 patients were enrolled: five males, mean age 57 years, disease onset 24 years. At OMA discontinuation, 88% were OCS-dependent with annual mean rate of 4.0 clinically significant exacerbations, 0.30 exacerbations needing emergency room visits or hospitalization; absenteeism due to disease was 10.4 days per patient. Switch to MEP improved all clinical outcomes, reducing total exacerbation rate (RR = 0.06, 95% CI 0.03–0.14), OCS-dependent patients (OR = 0.02, 95% CI 0.005–0.08), and number of lost working days (Δ = − 7.9, 95% CI − 11.2 to − 4.6). Pulmonary function improved, serum IgE, FeNO and eosinophils decreased. Mean annual costs were €12,239 for OMA and €12,639 for MEP (Δ = €400, 95% CI − 1588–2389); the increment due to drug therapy (+ €1,581) was almost offset by savings regarding all other cost items (− €1,181). Patients with severe eosinophilic asthma, not controlled by OMA, experienced comprehensive benefits by switching to MEP with only slight increases in economic costs.

Severe Eosinophilic Asthma

Eosinophilic asthma is a common phenotype of severe asthma, occurring in at least half of patients. In recent years, there have been significant changes in the approaches to the treatment of severe bronchial asthma and, above all, eosinophilic asthma. The article discusses the role of eosinophils in the pathogenesis of severe asthma, the detection of the phenotype of severe eosinophilic asthma, and modern approaches to targeting severe asthma with an eosinophilic phenotype using biological agents. A special emphasis is placed on preparations of monoclonal antibodies to interleukin-5, in particular, mepolizumab, recently approved for clinical use in our country.

Abstract Background Context:- Asthma is a heterogenous disease with various phenotypes, it is the most common chronic disease characterized by airway limitation due to bronchospasm and airway inflammation associated with excessive mucus secretion from agitated mucus gland that occur due to air way hyper responiveness. Purpose of the study Comparison between eosinophilic and non-eosinophilic asthma patients. Patients and Methods 100 bronchial asthma patients of age ≥ 18 years old divided into2 groups according to blood eosinophilia. All patients were subjected to: history. Total Asthma Control Test. Spirometry. Sputum eosinophil count. IgE levels 6-Skin prick testing (SPT). Nasal endoscopy. Results the mean age of all patients was (35.4 ± 12.8) years, majority (61%) of patients were males,; the mean ACT score was (18.7 ± 2); 39% of cases have obstructive pattern by spirometry, 39% of cases had abnormal nasal endoscopy, SPT had significant relation with asthma, there is significant correlation between total IGE,sputum eosinophilia with eosinophilic asthma. Conclusion Blood eosinophils had the highest accuracy in the identification of sputum eosinophilia in asthma. Total IgE values and sutum eosinophilia were markedly increased in patients with eosinophilic asthma more than patients with non-eosinophilic asthma.
