Filter by:Asthma is a chronic inflammatory disease of the airways that follows a strong circadian rhythm: Signs of inflammation and symptoms worsen especially in the early morning hours. The molecular circadian clock, which is a complex machinery of transcriptional and translational feedback loops, seems to reflect the inflammatory environment of peripheral blood leukocytes. Therefore, in this observational study the investigators will monitor the molecular circadian clock in patients with severe eosinophilic asthma before and during mepolizumab treatment. Our major goal is to evaluate the potential of the molecular circadian clock to serve as a prognostic marker for disease progression, treatment response or remission in patients with severe eosinophilic asthma. The molecular circadian clock will be monitored in blood and sputum leukocytes from patients with severe eosinophilic asthma before mepolizumab treatment, after 4 month of mepolizumab therapy, and once they reach remission under mepolizumab treatment. Effects will be compared to healthy controls and patients with mild-moderate asthma without mepolizumab treatment.
A phase I clinical research study aimed at determining mechanisms that regulate airway mucosal inflammation in asthma endotypes using intranasal administration of endotoxin (lipopolysaccharide from E. coli) in healthy controls and subjects diagnosed with asthma.
Study of the clinical evolution at 10 years of children from the SAMP cohort (severe asthma, eosinophilic or not, allergic or not) in order to understand the different possible evolutions of these phenotypes at different ages.
This study will assess the efficacy and safety of 610 as an adjunctive therapy in adult subjects with severe eosinophilic asthma.
Severe asthma is a debilitating condition associated with frequent symptoms, life-threatening exacerbations and corticosteroid side-effects. Exercise limitation due to exercise-induced bronchoconstriction, dynamic lung hyperinflation and comorbidity may be a strong determinant of the disease burden. Mepolizumab is a monoclonal anti-interleukin-5 (IL-5) antibody that reduces the rate of severe exacerbations, asthma symptoms and oral glucocorticoid requirement, and improves quality of life and work productivity in severe eosinophilic asthma. However, its impact on physical activity and exercise tolerance is unknown. We hypothesize that a 6-month treatment with mepolizumab is associated with an improvement in daily life physical activity and exercise tolerance in relation with enhanced ventilatory mechanics.
The study aim is to look at the effect of the regular use of inhaled corticosteroids on the response and received from mepolizumab treatment which you are receiving or had received before.
The IRIS study aims to investigate the way Mepolizumab affects the structure of the airway cells in patients with Severe Eosinophilic Asthma and how the immune function of these cells changes with treatment. The aim is to take samples of cells from the airways before starting Mepolizumab and after 6 months of treatment. These samples will be taken during a bronchoscopy (a camera test looking into the lungs) and we will analyse these cells in the laboratory. These investigations will allow us to better understand how Mepolizumab affects the cells within the airways.
This study is aimed at evaluation of the efficacy of mepolizumab 100 mg SC every 4 weeks in patients with severe eosinophilic asthma who have been treated for at least 12 months in several Polish allergy/asthma centres under the same protocol. Target population to be recruited has been set at 130 subjects from at least 6 asthma centers throughout the country. Data on dempgraphics and asthma status will be collected using questionnaires at 3 time-points: pre-MEPO, after 24 weeks of MEPO and after 1 year of MEPO administration (some of the outcomes will be observed every 4 weeks). Primary endpoints will include: - Asthma exacerbations measured at qualification for the treatment (in the period of previous 52 weeks) and at the 24th and 52nd week of the treatment. - Oral Corticosteroids use dose (documented at qualification for the treatment and at the 24th and 52nd week of the treatment).
This study will recruit patients who are being prescribed Mepolizumab as part of their standard clinical care for the treatment of severe eosinophilic asthma. Over the course of their treatment, research data (questionnaires) and research samples (blood, breath and urine) will be collected in parallel to standard clinical measurements. The data and samples will be investigated to help better understand how Mepolizumab works, why it doesn't work in certain patients and why it works very well in others. This will help prescribers better identify patients that will benefit from Mepolizumab.
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.
