NCT06465485
This is a prospective, multi-center, single-arm Phase 3b study designed to evaluate the potential benefit to patients if benralizumab treatment could enable reduction in asthma maintenance controllers while allowing patients to maintain asthma control in Chinese patients.
NCT05440656
Severe eosinophilic asthma (SEA) is associated with poor disease control and compromised health-related quality of life (HRQoL), leading to a substantial psychosocial and economic disease burden. Benralizumab (Fasenra®), an interleukin (IL)-5-alpha receptor monoclonal antibody, is approved as an add-on maintenance treatment for SEA. This study aims at collecting real-world data that extend beyond the clinical effectiveness of benralizumab to the participant-reported impact of treatment on their HRQoL, sleep quality, depression, anxiety, work productivity and activity impairment, but also on treatment effectiveness. Recent technological advances in portable spirometers and wearable activity trackers (WAT) to increase physical activity for participants with asthma, even for older participants, allow this study to collect data on lung function parameters and physical activity from such devices for the first time at a country level in Greece. Using a multi-aspect approach, this study will generate real-world evidence on a broad range of both well-established clinical and novel patient-centered outcomes which are critical to the assessment of the therapeutic benefit both from the physician's and the participant's perspective. All main study outcomes will be examined at various timepoints throughout the course of the 48-week observation period, starting as early as 4 weeks after treatment initiation, thus enabling the identification of 'early' treatment responders with a closer focus on patients' physical and psychological well-being and HRQoL in addition to asthma control and lung function metrics
NCT04159519
This is a multicentre, randomised, open-label, parallel-group, active-controlled, phase IV study to assess the reduction of daily Symbicort® maintenance to anti-inflammatory reliever treatment only in participants with severe eosinophilic asthma on Fasenra® treatment, while maintaining asthma control.
NCT04126499
Observational, retrospective study in adults (≥18 years) with severe asthma (maintenance treatment with high dose inhaled corticosteroids combined with long-acting agonist β2) and eosinophilic phenotype, who at the discretion of the investigator were candidates to receive benralizumab in the individualized access program approved by national health authorities. Primary Objective: To describe the demographic and baseline characteristics in patients with severe eosinophilic asthma who participated in the individualized access program approved in Spain and received at least one dose of benralizumab. Secondary Objectives: To describe clinical outcomes in severe eosinophilic asthma patients who received at least three doses of benralizumab in the individualized access program.
NCT04542902
Chronic airway inflammation rich in eosinophils is an important feature seen in asthma. Airway and blood eosinophilia is associated with increased rates of asthma exacerbations and more intense treatment. Recently, the existence of two distinct eosinophils subtypes was revealed-lung-resident eosinophils (rEOS), which maturate independently to interleukin (IL) 5, with the primary function to maintain tissue homeostasis, and inflammatory eosinophils (iEOS), which mature in IL-5-dependent manner and are mainly involved in immune responses. Eosinophils' effect on the airway remodeling in asthma depends not only on the activity but also by their viable number in the lungs. Blood iEOS infiltrate the airways mainly after the environmental stimulus like allergen and leave the airways with bronchial secretions. However, rEOS reside lung tissue for their entire lifetime regulating local immunity. Blood rEOS and iEOS ratio alters in asthma, compared with healthy controls. It is known that the predominant eosinophils subtype in allergic asthma are iEOS, while rEOS are basic subtype in severe eosinophilic asthma patients, moreover, they are different in adhesive properties and survivability as well. Distinct biological properties allows to speculate about their different functions in asthma, however, there are still little information. Data about differently expressed microRNA (miRNA) profiles in eosinophils in asthma suggests, that eosinophils subtypes can be distinct in non-coding RNA (ncRNA) - microRNA (miRNA), piwi-interacting RNA (piRNA) and long non-coding RNA (IncRNA) profiles that could describe their role in asthma pathogenesis and act as biomarkers to discern asthma phenotypes.
NCT04084613
A prospective multi-centre, non-interventional observational study, that will be conducted in several centers in Greece for a 2-year time period (completion date December 2020), to describe patient characteristics, medical history, and the clinical benefit of mepolizumab in patients with severe eosinophilic asthma newly initiated to the drug.
NCT03652376
This study investigates the effect of removing eosinophils from peripheral blood (using treatment with Benralizumab, which is approved for the treatment of severe eosoniphilic asthma) on circulating dendritic cells in patients with severe eosinophilic asthma.
