Active clinical trials for "Asthma"

The Korea-UK Precision Medicine Intervention in Severe Asthma (PRISM) study aims to identify molecular phenotypes of severe asthma by analyzing multi-omics data including genomics, epigenomics, transcriptomics, proteomics, metagenomics, and metabolomics.

This is a real-world, observational, prospective cohort study in patients with severe asthma recruited into the International Severe Asthma Registry (ISAR) and the US severe asthma registry (CHRONICLE) and followed-up for occurrence of new malignancies. The primary objective is to measure the incidence of malignancy in the overall severe asthma population as well as its relevant subgroups, including patients receiving benralizumab, patients receiving non-benralizumab biologics, and patients not receiving biologics. The secondary objective is to describe the clinical characteristics of new malignancy cases that develop in severe asthma patients and relevant subgroups.

A "Clinical Registry" is a database which contains clinical information about people with different medical conditions. They are used in many countries throughout the world to help medical teams to better understand specific diseases and improve the care and treatment of patients. The UK Severe Asthma Registry has been collecting data on patients attending Severe Asthma Clinics in the UK since 2007. After obtaining appropriate consent from patients to use their information, data is entered by the patient's own clinical team and it is kept up-to-date to follow clinical progress and response to treatments. Very strict controls are in place to make sure individuals cannot be identified from the Registry and all information available from the National Registry is anonymous. Apart from the local clinic team, occasionally trusted third parties will also be able to identify you, if required to do so, on a strict need-to-know basis. This is necessary to ensure that the Registry works efficiently, or as a part of a Research Project, previously approved by a Research Ethics Committee. Data from the Registry has a number of uses including judging which severe asthma treatments are of greater benefit, to identify different subgroups of severe asthma and trial new therapies and to provide information for planning future services for people with severe asthma. The use of any information from the UK Severe Asthma Registry requires approval of the Steering Committee which is made up of the refractory asthma specialists from across the UK and who will have access to data protection, legal and ethics expertise where necessary, to safeguard the use of data. If the Registry closes, data will be returned to the local clinic team if requested, otherwise it will be destroyed. Participation is entirely voluntary and patients can withdraw consent form the Registry at any time by informing their local clinical team. The Data Controller from the UK Severe Asthma Registry is Queen's University Belfast and the Data Processor is Dendrite Clinical Services Ltd which is a commercial provider of database and registry systems.

The Genomics and Metagenomics of Asthma Severity (GEMAS) study aims to assess the role of genomics, the microbiome, and the interaction between them in the development of asthma exacerbations in European patients with asthma.

Severe asthma is a condition characterized by a lower sensitivity to high doses of inhaled corticosteroids combined with a second controller, most often a long-acting bronchodilator. It concerns approximately 5% of asthmatics. Treatment failure and co-morbidities induced by systemic corticosteroid therapy can cause debilitating dyspnea, limited physical activity, and impaired quality of life. Severe asthma could therefore be associated with major presenteeism, defined as the presence of an employee at work despite his health issues and which implies a limitation of the employee's productive capacity. Uncontrolled asthma and co-morbidities of asthma have been shown to be associated with a decrease in work productivity that includes absenteeism and presenteeism. Although there is little data, a recent study found a decline in work productivity in severe asthma. Various factors associated with presenteeism could be involved, such as asthma control, frequency and severity of exacerbations, comorbidities, or treatments. Biotherapies targeting the signaling pathways involved in airway inflammation improve asthma control, decrease the frequency of asthma exacerbations which are major determinants of quality of life, improve lung function, and allow oral steroid sparing. Biotherapies could therefore be associated with a decrease in presenteeism. The objective of the study is to describe the evolution of presenteeism at work, evaluated by the WPAI: Asthma, after 6 months of treatment by biotherapy and to identify factors associated with this evolution

This study aims to prospectively assess the asthma control and management of asthma patients who are on step 4, 5 asthma of GINA in Hong Kong (on at least medium-dose ICS-LABA as controller therapy for asthma) and also observe their exacerbations over 2 years. In addition, this study will also assess patients who are on biologics for their suitability and outcome. The investigators hope this study will be able to provided data regarding the management and outcome of patients who have difficult-to-treat and severe asthma. The investigators plan to build a biologic registry for asthma that would be able to help local doctors to gain experience to the use of these new and expensive medications. This is a multi-centre study involving public hospitals in Hong Kong. This study is important as this will generate local data for healthcare planning for severe asthma in Hong Kong.

The COVID19 pandemic is having an immeasurable impact on the economy and on morbidity and mortality. Knowledge and scientific evidence about this disease is advancing rapidly, but it is not yet known whether asthmatic patients suffering from COVID19 have an exacerbation of asthma, or whether this viral infection has an impact on control and lung function in the short to medium term. The aim of this study is to define the changes that occur in these two parameters in asthmatic patients suffering from COVID19. To this end, asthmatic patients who have suffered a SARS-CoV-2 infection and who have required an emergency consultation or hospitalisation will be collected in a pneumology consultation and matched by age, sex and severity of asthma with a group that has not suffered the same. Both will be followed for one year, and lung function will be tested at six months and exacerbations and changes in ACT during the following year. These data are intended to improve the available knowledge on the impact of IDVC19 on asthma patients with a view to making appropriate recommendations, prevention and treatment adjustments in line with the results obtained.

The project aims to increase the diagnostic accuracy in occupational asthma (OA), with emphasis on Irritant Induced Asthma (IIA). Currently, most patients are evaluated in occupational medicine by comparing the exposure and symptom characteristics with epidemiological data. Biological markers may be present in AA, but presently not in IIA. The majority of cases evaluated are considered as possible IIA, i.e. low-dose multiple exposures. VOC features will be analyzed with the Breath Biopsy® and TD-GS-MS (Owlstone Medical Ltd, UK).

The goal of this observational study is to explore the health impacts of exposure to nontailpipe vehicle air pollution. The main question it aims to answer is: Does short term exposure to increased non-tailpipe course mode PM induce negative respiratory responses in adults living with asthma? We will recruit 48 non-smoking adults with mild-moderate asthma. Participants will be recruited from central and east London Participants will be exposed to three contrasting air quality environments, in field laboratories at the following locations: High-speed continuous traffic location, to enhance tire wear emissions An urban background location away from nearby traffic sources A busy road junction characterized by stop-go traffic to enhance emissions from brake wear Sites 1 and 2 are permanent air quality measurement supersites. Site 1 is located close to a major trunk road in Central London (Marylebone Road). Site 2 is a suburban park in South London (Honor Oak Park). An additional measurement location will be established at Imperial College London's (ICL) White City campus (Site 3) for the duration of the study using ICL's mobile measurement facility, equipped with the same highly time-resolved chemical composition measurement capability as the supersites. To maximise exposure to different air quality environments participants will intermittently cycle on static exercise bikes at a standardised intensity of 60% estimated VO2max for a duration for 2.5 hours at the field laboratories. Comparators variables: Air quality will be monitored at all three sites for the duration of the testing visits (approximately 5 hours). Air quality parameters that will be recorded are PM2.5, PM10, NO2, NO, NOX, O3, Organic Mass, NO3, SO4, NH4, elements and black carbon. Outcome variables: The primary outcome of the study is lung function as measured by Forced Expiratory Volume in one second (FEV1). With secondary health endpoints including: Spirometry (FVC, FVC/FEV1 ratio, z Scores), fractional expired nitric oxide (FeNO), oscillometry, asthma symptoms, MRC breathlessness score, asthma control test and Asthma Quality of Life Questionnaire (AQLQ). Blood, nasal mucus and urine samples will be collected. Measure will be collected before after and 24 hours after exposure.

Asthma is a chronic respiratory disease whose goal of therapeutic, educational and preventive care is to prevent the onset of acute crisis, the most serious of which are life threatening. A general population survey shows a greater prevalence of asthma in the French West Indies compared to hexagonal France, but there is no data to our knowledge on asthma exacerbations requiring pre and intra-hospital emergency services, nor on the clinical severity or on the adequacy of the therapeutic care. Asthma exacerbations, in particular serious forms requiring immediate admission to the Emergency Department or Intensive Care Unit or leading to hospitalization, can be considered as a failure in the prevention of crisis and therefore disease control. The management of acute or subacute asthma exacerbations is however well codified in expert recommendations, renewed annually by the Global Initiative for Asthma (GINA). These recommendations specify not only the initial care, but also the strategy and modalities of return home and post-emergency follow-up. Recently the French Language Resuscitation Society (SRLF) and the French Society of Emergency Medicine (SFMU) jointly published formalized expert recommendations (RFE) on the management of asthma exacerbations (Le Conte 2019). These RFEs still remain the benchmark in France for adequate management of asthma exacerbations for adults and children. Despite these updated recommendations, field observations often show inadequate care, both in the emergency and in the post-emergency period.
