Active clinical trials for "Asthma"

The objective of this study is to investigate whether electromyography of the diaphragm during sleep in asthmatic children can be used to objectively monitor asthma control.

Rational: The possible contribution of methacholine challenge test via spirometry to the clinical diagnosis of young children with various respiratory symptoms, the most appropriate spirometry index, and the proper cutoff point concentration that will define airway sensitivity have not yet been explored. Objectives: To assess airway reactivity by spirometry in a large group of children aged 3-6years with various respiratory symptoms.

The purpose of this study is to see if the addition of budesonide to oral corticosteroids will result in a decrease in relapse rates compared to oral corticosteroids alone in children who are discharged from the ED after an asthma exacerbation. Secondly, that there will be an improvement in lung function, a decrease in beta-2 agonist use and an improvement in health-related quality of life compared to placebo.

Asthma is one of the most common chronic respiratory diseases. Previous study found a series of differentially expressed genes and proteins (transgelin-2, metallothionein-2, ezrin) in asthmatic rat. The aim of the study is to investigate the changes and associations of these gene with asthma in human.

Pharmacodynamic bioequivalence study of Albuterol Sulfate Inhalation Aerosol 0.09 mg

A phase IIb study in patients to evaluate CYT003- QbG10 versus placebo, in patients with mild to moderate allergic asthma not sufficiently controlled on inhaled steroid. Altogether 170 patients, randomized to two treatment groups will be included. Key outcome measures are patient reported parameters on their asthma

Approximately 480 (120 per group) would need to complete the 6 weeks of treatments.

The inflammatory process that leads to the development of asthma may be present before the onset of asthma symptoms and cause a certain degree of airway hyperresponsiveness. Without treatment it may induce irreversible airway structural changes that are associated with permanent changes in airway functions, persistent airway hyperresponsiveness and lead to the development of asthma symptoms. Atopic subjects with asymptomatic airway hyperresponsiveness and first degree relatives with a history of asthma are at higher risk to develop symptomatic asthma. Early treatment of airway inflammation in these predisposed subjects with " borderline " or mild airway hyper-responsiveness could prevent the development of asthma symptoms, and reduce or even normalize airway responsiveness. In very mild asthmatic subjects (bronchodilator need < thrice a week), early anti-inflammatory treatment can lead to " normalisation " or airway responsiveness in a significant number of subjects and prevent the need for subsequent regular therapy. This is particularly true for those showing blood/sputum eosinophilia. Objectives: To compare perception of bronchoconstriction, pulmonary function and airway inflammation in subjects with mild symptomatic asthma and asymptomatic asymptomatic airway hyperresponsiveness Methods: To compare the influence of inhaled fluticasone propionate 250 mcg/day for 3 months followed by 100 mcg/day for 9 months on airway inflammation and methacholine responsiveness in a double-blind, placebo-controlled, parallel groups study including non-smoking atopic subjects with mild asthma and asymptomatic airway hyperresponsiveness

This prescreening study is being conducted to diagnose ABPA in selected patients with asthma and to increase the potential number of eligible participants for the ongoing Study 601-0018 of PUR1900 in subjects with ABPA. See: NCT05667662. Additionally, this prescreening study may provide information that could assist the conduct of future studies conducted by Pulmatrix.

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.
