Filter by:This study is conducted to assess the ease of device mastery of a placebo SYMBICORT TURBOHALER vs a placebo Budesonide/Formoterol SPIROMAX device among healthcare professionals in-training (HCP).
This is a blinded observer randomized controlled trial comparing two nebulizer devices. The objective of this study is to evaluate the efficacy of two different nebulizers.
This research study is being done to learn more about severe asthma by comparing people with severe asthma to those with milder forms of asthma and people without asthma, at baseline and over time. Individuals are being asked to join a research study to help understand the differences in the lungs and blood of participants with severe asthma compared to those with milder asthma and healthy individuals, as well as differences in overall health. Investigators also want to determine whether these differences predict asthma-related and biologic outcomes over 1 year of follow up.
This study aimed to determine the efficacy and safety of QAW039 and QAW039 450 mg compared to placebo, when added to GINA (Global Initiative for Asthma) steps 4 and 5 standard-of- care (SoC) asthma therapy (GINA 2016) in the following two populations: - patient with inadequately controlled severe asthma and high eosinophil counts (eosinophil count at Visit 1 ≥250 cells/ µl) (sub-population) - patients with inadequately controlled severe asthma (overall study population) Inadequate control is defined as partly controlled or uncontrolled asthma (GINA 2016)
The purpose of this study is to determine mean or median of fractional exhaled nitric oxide (FeNO) in Thai atopic asthmatic children that divided into subgroups due to asthma exacerbation according to the global initiative for asthma guideline.
The aim is to study the effect of OC000459 on eosinophilic airway inflammation and asthma control in subjects with severe, refractory eosinophilic asthma.
The steroid sparing effect of anti interleukin (IL-5) monoclonal antibody has been proven, but the effectiveness of subcutaneous (SC) compared to intravenous (IV) administration of these drugs to suppress airway eosinophilia is still under debate. As part of a previous study, 100mg of mepolizumab were administered subcutaneously to a group of subjects with prednisone-dependent eosinophilic asthma. Despite this intervention, 50% of the subjects (15 patients participated in this study) had persistently elevated sputum eosinophil counts. The same 15 patients will be invited to participate in the current study, and if they provide their informed consent, will receive 2 monthly doses of placebo, followed by 4 monthly doses of IV reslizumab. The primary outcomes are blood and sputum eosinophils, and the secondary outcomes include sputum and blood Innate lymphoid cell-2 (ILC2) cells, cluster of differentiation 4 (CD4+) cells, cluster of differentiation-8 (CD8+) cells, cluster of differentiation-34 (CD34+), Eosinophil-Basophil cluster cells (Eo/B progenitor cells), forced expired volume in 1 second (FEV1), asthma control questionnaire (ACQ) and number of eosinophilic exacerbations. Measurements of the outcomes will be done before placebo, after placebo and after IV reslizumab. This study design will determine whether IV reslizumab is effective in suppressing airway eosinophilia in prednisone-dependent patients.
The combination of asthma and being a carrier of genetic variants (mutations and / or polymorphisms) in the CFTR gene variant would cause bronchial asthma with mucus hypersecretion. This phenotype is characterized by a more severe disease, in terms of control, quality of life, exacerbations and lung function, and a different asthma the bronchial hypersecretion without inflammatory phenotype.
This is a research study to find associations between asthma symptoms and sleep patterns and physical activity among adolescent patients with persistent asthma. The Investigators will collect Fitbit® sensor data and survey data from each adolescent enrolled in the study.
Poor adherence to asthma controller medication may link to poor asthma outcome. A metered dose device with built-in dose counter helps physicians to monitor drug compliance in asthma patients. Mobile-phone based self management opens a window for better asthma control. The present study aims to investigate the relationship between the adherence to controller medication of combined inhaled corticosteroid/long acting beta2-agonists, assessing by integrated dose counter, and the level of airway inflammation and asthma control. Moreover, the investigators also use a new asthma self-management Apps to enhance drug compliance. With the application of the new, easily available tools, the investigator expect to increase adherence rates, and hence, to reduce airway inflammation and improve the level of asthma control.
