ABSTRACT

OBJECTIVE: Patients with severe eosinophilic asthma experience high risk of exacerbations and reduced quality of life. Benralizumab, a monoclonal antibody binding to IL-5 receptor α subunit, is an approved drug for its treatment. The objective was to describe clinical remission after benralizumab prescription in routine clinical practice. METHODS: Retrospective multicenter study with data from four hospitals in Valencian Community (Spain) with asthma units between 2019 and 2020. Data was gathered at baseline and after 12 months. We considered clinical remission after 1 year if the patient remained without exacerbations and use of systemic corticosteroids and with good clinical control and normal lung function. RESULTS: Data from 139 patients was gathered. At the 12-month follow-up, 44.1% were in clinical remission, since 84.0%, 77.5%, 51.0% and 95.5% of patients did not experience exacerbations, had total asthma control test score of ≥20, prebronchodilator FEV1 of ≥80% and did not use systemic corticosteroids. A significant reduction of long-acting muscarinic antagonists (p = 0.0001), leukotriene receptor antagonists (p = 0.0326), oral corticosteroids (p < 0.0001) and short-acting beta agonists (p = 0.0499) was observed. Baseline factors with greatest individual influence on clinical remission were employment situation, tobacco use, comorbidity number, eosinophil value, number of exacerbations, FEV1, emergency visit number, and ACT, MiniAQLQ and TAI scores. Final analysis of multiple logistic regression indicated that having baseline FEV1 value below 80% increases remission chance 9.7 times a year compared to FEV1 >80%. CONCLUSION: Clinical remission after treatment with benralizumab is achievable in a high percentage of patients with severe asthma eosinophilia not controlled in real life.

ABSTRACT

Objetivo: Evaluar el gasto sociosanitario tras la incorporación de omalizumab al tratamiento estándar en el control del asma grave, así como analizar su efectividad, en condiciones de práctica clínica. Método: Estudio observacional, retrospectivo y multicéntrico realizado en 12 servicios de neumología de la Comunidad Valenciana. Se analizaron datos de 186 pacientes. Se compararon resultados del año previo y los cinco años posteriores a la incorporación de omalizumab. La efectividad se calculó a partir del incremento de tres puntos en el Asthma Control Test y la reducción del número de exacerbaciones anuales. La utilidad se calculó mediante el número de años de vida ajustados por calidad. En la evaluación económica se incluyeron costes directos e indirectos. Los resultados se expresaron en términos de relación coste-efectividad incremental y relación coste-utilidad incremental. Resultados: Se detectaron mejoras significativas en la función pulmonar, el control del asma, la calidad de vida y el número de años de vida ajustados por calidad, entre el año anterior y el posterior al inicio de omalizumab. Teniendo en cuenta los costes directos e indirectos, la relación coste-efectividad incremental por exacerbación evitada fue de 1.789,28 Euros (intervalo de confianza 95%: 1.019,13-3.038,12) y de 4.569,38 Euros (intervalo de confianza 95%: 3.442,86-6.075,05) por incremento de tres puntos en el Asthma Control Test. La relación coste-utilidad incremental por número de años de vida ajustados por calidad ganada fue de 50.239,98 Euros (intervalo de confianza 95%: 37.209,88-68.923,84). Conclusiones: La introducción de omalizumab en el tratamiento del asma grave es efectiva en condiciones de práctica clínica. Disminuye los costes directos e indirectos y proporciona mejoras significativas en el estado de salud de los pacientes


Objective: To assess socio-sanitary expenditure after the addition of omalizumab to standard treatment in the control of severe asthma and to analyse its effectiveness under standard clinical practice. Method: Observational retrospective multicentre study conducted in 12 pneumology services in the Valencian Community, Spain. Data from 186 patients were analysed. Results of the year before and after the addition of omalizumab were compared. Effectiveness was calculated based on a 3-point increase in the Asthma Control Test and a reduction in the number of annual exacerbations. Utility was calculated by the number of quality adjusted life years. The economic assessment included both direct and indirect costs and results were expressed in terms of incremental cost-effectiveness and incremental cost-utility ratio. Results: Significant improvements were found in lung function, asthma control, quality of life, and quality adjusted life years between the year before and after the introduction of omalizumab. Taking into account direct and indirect costs, the incremental cost-effectiveness for each avoided exacerbation was Euros 1,789.28 (95% CI: Euros 1,019.13-3,038.12) and Euros 4,569.38 (95% CI: 3,442.86-6,075.05) per 3-point increase in the Asthma Control Test score. The incremental cost-utility ratio per quality adjusted life years gained was Euros 50,239.98 (95% CI: 37,209.88-68,923.84). Conclusions: The addition of omalizumab to the treatment regime of patients with severe asthma is effective under standard clinical practice, decreases direct and indirect costs, and provides significant improvements in the health status of patients

ABSTRACT

OBJECTIVE: To assess socio-sanitary expenditure after the addition of omalizumab to standard treatment in the control of severe asthma and to analyse its effectiveness under standard clinical practice. METHOD: Observational retrospective multicentre study conducted in 12  pneumology services in the Valencian Community, Spain. Data from 186  patients were analysed. Results of the year before and after the addition of  omalizumab were compared. Effectiveness was calculated based on a 3-point  increase in the Asthma Control Test and a reduction in the number of  annual exacerbations. Utility was calculated by the number of quality  adjusted life years. The economic assessment included both direct and  indirect costs and results were expressed in terms of incremental cost- effectiveness and incremental cost-utility ratio. RESULTS: Significant improvements were found in lung function, asthma control, quality of life, and quality adjusted life years between the  year before and after the introduction of omalizumab. Taking into account  direct and indirect costs, the incremental cost-effectiveness for each avoided  exacerbation was € 1,789.28 (95% CI: € 1,019.13-3,038.12) and € 4,569.38 (95% CI: 3,442.86-6,075.05) per 3-point increase in the Asthma Control Test score. The incremental cost-utility ratio per quality adjusted life years gained was € 50,239.98 (95% CI: 37,209.88-68,923.84). CONCLUSIONS: The addition of omalizumab to the treatment regime of patients with severe asthma is effective under standard clinical practice, decreases direct and indirect costs, and provides significant  improvements in the health status of patients.
