Filter by:Primary Objective: • To assess the effect of dupilumab on lung inflammation and related changes in airway volumes detectable by functional respiratory imaging Secondary Objective: - To evaluate the effect of dupilumab at Week 24 on bronchodynamics, hyperinflation, airway resistance, airway wall thickness, ventilation defects and mucus plugging derived from high-resolution computed tomography (HRCT) scans, patient-reported outcomes, FeNO and spirometry. - To evaluate safety of dupilumab
The effects of regular exercise on asthma control has not yet been well demonstrated. The aim of this study is to investigate the impact of submaximal physical exercise on quality of life, on symptomatic control, and on bronchial and systemic inflammatory markers in patients with persistant asthma.
To improve the safety of diagnosis and therapy for a set of conditions and undifferentiated symptoms for hospitalized patients, the investigators will employ a set of methods and tools from the disciplines of systems engineering, human factors, quality improvement,and data analytics to thoroughly analyze the problem, design and develop potential solutions that leverage existing current technological infrastructure, and implement and evaluate the final interventions. The investigators will engage the interdisciplinary care team and patient (or their caregivers) to ensure treatment trajectories match the anticipated course for working diagnoses (or symptoms), and whether they are in line with patient and clinician expectations. The investigators will use an Interrupted time series (ITS) design to assess impact on diagnostic errors that lead to patient harm. The investigators will perform quantitative and qualitative evaluations using implementation science principles to understand if the interventions worked, and why or why not.
This study aimed to investigate the dental caries experience, periodontal health and salivary properties of asthmatic and non-asthmatic children ⁄ adolescents.
Asthma is more common in females than in males but the difference has not been explained yet. Group 2 innate lymphoid cells (ILC2) have recently emerged as critical players in the initiation of allergic responses but their implications in the difference between males and females in terms of asthma prevalence has not been fully studied. The aim of this project is to compare the proportion of ILC2 in blood between males and females with asthma.
Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation. This is a study about dupilumab which is a drug approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate to severe asthma. Dupilumab is a medication that blocks pathways that cause asthmatic inflammation in the lungs, leading to symptoms and worsening lung function. During this study, subjects will be given either dupilumab or placebo and will subsequently be exposed to the the "common" cold virus (rhinovirus). The virus that the investigators are using has been safely used before in many studies like this involving thousands of volunteers, and the safe use of the virus in this research study has been reviewed by the FDA. The investigators will track asthma symptoms during the study with lung function tests, questionnaires, specimen collection, biomarkers, and physical exams. For data analysis the investigators will assess the samples collected to determine changes in the treatment groups. The investigators will also asses the symptom scores and deviations from baseline measures for lung function.
Serum samples of asthmatic patients will be screened for serum biomarkers
Asthma, which are one of the most important causes of morbidity and mortality both in the world and in our country, constitute a very serious social and economic burden. An estimated 300 million people suffer from asthma worldwide, which is a major public health problem. Asthma is complex and heterogeneous chronic airway diseases that require a multifaceted approach. In asthma, small airways represent key regions of airflow obstruction. Although small airway dysfunction is known in chronic airway diseases, the importance of small airway dysfunction on disease control, exacerbations and quality of life, and the importance of taking place among treatable targets is not clear. Thus, there is an unmet need to assess its role in the control of the disease. Therefore, our primary aim in the study is to determine the frequency of small airway dysfunction measured by impulse oscillometry in Asthma patients. Our secondary aim is to evaluate the role of small airway dysfunction in disease severity, disease phenotypes, disease control, quality of life and its effect on predicting the risk of exacerbation and its role among treatable targets in Asthma.
The purpose of this study is to evaluate the effectiveness of two different ways to teach hospitalized children how to use a metered dose inhaler and to follow-up after discharge home from the hospital to determine durability of the education.
GSK3772847, an anti-interleukin (IL) 33-receptor monoclonal antibody, is a novel treatment for asthma. The purpose of this study to evaluate the safety and tolerability, PK and PD of single ascending doses of GSK3772847 administered subcutaneously (SC) to healthy participants. This study will also establish the bioavailability of SC formulation and evaluate the safety in particular injection site tolerability of route. Participants will either receive a single dose of 70 milligram (mg) GSK3772847 or placebo in (Cohort 1) and 140 mg GSK3772847 or placebo in Cohorts 2, 3 (Japanese participants) and 4 (Chinese participants). The site of injection will be upper arm; abdomen or thigh for cohorts 1 and 2 with cohorts 3 and 4 will receive injections in the upper arm only. Approximately, the total duration of study will be up to 89 days.
