Filter by:This is a single center study of 60 subjects including those with asthma and mucus plugging, those with asthma and without mucus plugging, and healthy controls. Screening data will be reviewed to determine participant eligibility. Participants who meet all inclusion criteria will participate in image-guided bronchoscopy ("virtual navigation bronchoscopy" [VNB]) to sample airway biospecimens in mucus plugged and control airways.
The purpose of this investigator-initiated study is to evaluate the effects of oral curcumin supplementation versus placebo in adult patients with moderate to severe asthma. Curcumin, a derivative of turmeric, has been shown in animal models to inhibit the secretion of pro-inflammatory cytokines and decrease airway constriction and hyperreactivity with only a few observational studies available in humans with discordant results.
Clinical trial to demonstrate whether, in patients with moderate asthma, to treat with IC / LABA a medium dose, but not controlled, to achieve a similar degree of control by making a progressive increase of that treatment (CI / LABA a high dose) versus switching to fluticasone / Formoterol K-Haler at medium dose, under conditions of usual clinical practice.
The purpose of this study is to compare treatment with QVM149, an inhaler that contains three types of asthma medications compared to an inhaler that contains two types of asthma medications. Both inhalers contain an inhaled corticosteroid, which reduces inflammation in the lungs, and a medication that helps to open up the airways. The investigational inhaler, QVM149, contains a third medication that also works to open up the airways. The investigators will measure the difference in these two treatments with magnetic resonance imaging (MRI) using a special technique using xenon gas to show how gas spreads in the lungs. In healthy lungs, the gas fills the lungs evenly, but in unhealthy lungs, the gas may fill the lungs unevenly and they will appear patchy. The patchy areas are called ventilation defects. A CT of the chest will be done to assess the structure of the lungs. The investigators will also use lung function testing and questionnaires to evaluate the differences between these therapies.
This is a Phase IIa, double blind, randomized, parallel group, placebo controlled multi centre study to evaluate the effect of AZD8154 (administered via nebulizer daily [QD]) on allergen-induced inflammation in subjects with mild allergic asthma challenged with an inhaled allergen. Approximately 36 subjects who meet all eligibility criteria will be randomized (1:1) to receive either AZD8154 or placebo.
The overall objective of this study is to better understand the respiratory mechanisms provoking dyspnea on exertion in obese asthmatic children.
New treatments have been developed for asthma that are good at preventing asthma attacks and improving day-to-day symptoms. Alongside the development of these new drugs, there are new ways of measuring how the lung is affected by asthma. In particular, investigators have developed ways of seeing how air moves in the lungs of people with asthma, using MRI scanning. This study aims to see how quickly these new drugs result in changes in the way the lung is working, as seen in the MRI scans and other breathing tests. This will help clinicians in the future to decide who is likely to respond to these new medicines, and once patients have started taking the drugs, will help clinicians to decide whether long term treatment is likely to benefit the people receiving them. In this study, the investigators plan to do extra breathing tests and MRI scans on people who are receiving the drug as part of their usual clinical care. The study will not change an individual's treatment, but will give the investigators more information about the patients' illnesses and the way the patients' bodies respond to treatment.
Phase IV, open-label study will evaluate effects of Benralizumab in the treatment of severe asthma in patients with allergic bronchopulmonary aspergillosis
This is an exploratory, randomized, subject- and investigator-blinded, placebo-controlled mode-of-action study to demonstrate the anti-inflammatory effects of fevipiprant compared to placebo after 12 weeks of treatment in 48 moderate to severe asthma patients with sputum and blood eosinophilia.
Approximately 480 (120 per group) would need to complete the 12 weeks of treatments.
