Filter by:The study will assess the effects of two drugs, glycopyrronium and indacaterol, taken either as monotherapy or in combination, on the methacholine dose-response curve. This will allow for further elucidation of the mechanisms of each drug in human participants.
The purpose of this study is to measure the density of a temperature-sensitive protein, named TRPV1, in the airway mucosa tissue of both non-asthmatic and moderate to severe persistent asthmatic patients. This study may generate information for developing new therapeutic strategy.
Chronic respiratory diseases (CRDs) affect the airways and other structures of the lungs and thereby lead to ventilation inhomogeneity. The most common CRDs in children are asthma, bronchiectasis and cystic fibrosis (CF). All three are obstructive diseases. However, while asthma is mostly characterized by obstruction due to bronchoconstriction of the airways, obstruction in bronchiectasis and CF originates primarily from mucus retention due to abnormal airway clearance mechanisms. The Nitrogen Multiple Breath Washout test (N2-MBW-test) is a robust and sensitive detector of early pulmonary changes and ventilation inhomogeneity. The minimal cooperation which is required for this test makes it very convenient for use in any age category. Research on LCI described it as a reliable indicator of obstructive lung disease in pediatric CF patients as from 6 years of age. Whether LCI is a reliable parameter for early lung disease in asthma children is less clearly demonstrated. No data were found on LCI calculated from the N2-MBW-test in children with bronchiectasis.
Primary Objective: To evaluate the efficacy of dupilumab in children 6 to less than (<) 12 years of age with uncontrolled persistent asthma. Secondary Objective: To evaluate in children 6 to <12 years of age with uncontrolled persistent asthma: - The safety and tolerability of dupilumab. - The evaluate the effect of dupilumab in improving participant reported outcomes including health related quality of life. - The dupilumab systemic exposure and incidence of anti-drug antibodies. - The evaluate the association between dupilumab treatment and pediatric immune responses to vaccines: any vaccination for tetanus, diphtheria, pertussis and/or seasonal trivalent/quadrivalent influenza vaccine.
This study raises two main hypotheses: 1) Asthmatics patients who present with bronchial hypersecretion differ phenotypically from asthmatic patients without hypersecretion and 2) mucins in asthmatic patients with hypersecretion of bronchial mucus and the expression of TLRs differ from non-mucus hypersecretory asthmatics patients.
Reslizumab is a type of medicine called a monoclonal antibody that is made in the research clinic; it works by blocking a specific protein in the body called interleukin-5. The study medicine, reslizumab, is not yet approved for doctors to treat patients with EGPA. It is considered an experimental drug in this study.
This study will evaluate whether treatment with L-citrulline, which is an amino acid found in some foods, can increase levels of L-arginine and thereby restore the concentration of nitric oxide (NO) in the airways.
Asthma is characterized by recurrent episodes of bronchospasm, bronchial hyperresponsiveness and chronic airway inflammation and pharmacological treatment for this condition is done with bronchodilators and anti-inflammatory.
The purpose of this study is to evaluate the clinical efficacy of traditional Chinese medicine in the treatment of asthma, and to promote the application in community hospitals.
This is an exploratory study with the following primary objectives: 1) to establish that PET/CT of the lung can reliably distinguish healthy, non-asthmatic participants from participants with severe asthma and an eosinophilic phenotype and 2) to examine the utility of PET/CT for demonstrating that reslizumab produces a reduction in lung inflammation in participants with severe asthma and an eosinophilic phenotype .
