Tezepelumab in the Treatment of Emergency Room Asthma in Adults (TERAA)

Adults with severe asthma may have sudden worsening shortness of breath that results in their going to Emergency Department for urgent care. Emergency Room visits for asthma management across Alberta have been reviewed and it has been found that adults frequently need to return for repeated worsening. This is a large drain on health care resources as well as being very distressing for individuals with asthma. Occasionally this results in admission to hospital and rarely may lead to death. People are often treated with steroids to try to prevent the need for Emergency Room visits even though steroid medications have many long term bad side effects. A new medication for patients considered to have severe asthma has been recently approved by Health Canada. This medication, Tezepelumab, is a monthly injection and it helps control asthma in adults regardless of the underlying cause. The study will examine if starting Tezepelumab, compared with a placebo, in the Emergency Room will help settle symptoms of asthma and prevent future worsening requiring repeated Emergency Room visits or the need for courses of outpatient steroid medications.

Beyond EOsinophils: proteoMICS to Identify Potential Biomarker of Organ Damage and Response to MEPOLIZUMAB in EGPA

Aim of the study is to identify potential biomarkers, through a proteomic approach, which could be used to evaluate organ damage and predict the response to mepolizumab in a cohort of patients affected by EGPA. Proteomic analyses will be performed using a proteomic platform, based on a nano-HPLC- couplet to an high resolution ESI-MS device, on three types of biological matrices: blood, saliva and sputum samples in both EGPA and severe asthmatic patients (as controls) at baseline and at different time points after starting treatment with mepolizumab, an anti-IL-5 drug, in order to cluster patients and to analyze the effect of the therapy during treatment, assessing the disease progression on three key aspects: lung function and symptoms control, vasculitis and neuropathy. Plasma analysis will provide an overview of quantitative/qualitative proteomic variations at systemic level after drug administration; however, a less invasive procedure is often sufficient and would improve trial recruitment. On this regard, saliva is a biological fluid well suitable to be used in proteomic investigations for suggestion of potential disease biomarkers and includes various potential advantages compared with blood sample collection such as lower overall cost, lower infection risk, increased patient convenience, acceptability, compliance and uptake. Moreover, the protein composition of the human saliva includes both specific proteins of the oral cavity and proteins common to other tissues and bodily fluids, so saliva prognostic and diagnostic role is particularly interesting. Consequently, the plan is to compare the proteomic results of the non-invasive saliva testing to that of blood examination. These data may be a further step to untangle the mechanisms of the disease and to characterize treatment's response, in the contest of a phenotype/endotype asthma management.

Remission in Adults With Severe Asthma in Thailand

The goal of this observational study is to determine the prevalence of remission among adults with severe asthma, as well as the factors associated with remission in Thailand. The main question the study aims to answer is: What is the prevalence of remission among adults with severe asthma in Thailand? Participants will complete questionnaires on asthma symptoms and undergo pulmonary function testing and a blood test once.

Bronchial Thermoplasty for Adults With Severe Asthma in the Biologic Era

Rationale: For patients with severe asthma that remain uncontrolled with exacerbations despite biologics or patients who are not eligible for biologics, there is no reimbursed treatment other than pulmonary rehabilitation in the Netherlands. Pulmonary rehabilitation is known to have a limited effect for a limited amount of time. Bronchial thermoplasty or bronchial ablation (BT) is a non-pharmacological treatment for asthma aiming to restore abnormal airway function by using an endobronchial approach. Previous RCT's reported efficacy on exacerbations and asthma related quality of life (AQLQ), but were performed before large availability of biologic treatments. Although a single BT treatment is not without costs, these costs seem to outweigh the costs that can be saved by the long-term (\>5 years) lowering effect of BT on the frequency of exacerbations and hospitalizations and omitting long term use of trials and switches of biologics. Therefore, the investigators hypothesize that BT, in the era of biologics, is superior (in terms of exacerbations and quality of life) over standard care and cost-effective in patients whose asthma remains uncontrolled despite optimal anti-inflammatory treatments including biologics, and the investigators propose to test this hypothesis in a RCT. Objective: To investigate the impact of BT as compared to standard of care in severe asthma patients that remain uncontrolled despite standard treatment including adequate doses of inhaled preventer therapies with or without biologics on: 1. rate of exacerbations 2. asthma related quality of life (AQLQ) 3. 1-year and 5-year cost-effectiveness and cost utility Study design: Investigator-initiated randomized, multicenter, parallel-group interventional RCT of severe asthma patients undergoing either BT (active arm) or standard care (control arm). Study population: Adult, uncontrolled severe asthma patients despite optimal medical therapy including one or more trials of treatment with a biologic or ineligible for biologic treatment AND 2 or more severe asthma exacerbations in the previous year AND FEV1 ≥ 50% predicted. Intervention: BT (active arm) versus standard care (control arm). Main study parameters/endpoints: The primary endpoint of this study is the between group difference in severe exacerbation rate after 12 months of follow-up. The main secondary endpoints are between group differences after 12 months of follow-up and within group differences before and after intervention or standard care. Parameters that will be explored are: AQLQ (minimal clinically important difference \>0.5), ACQ (minimal clinically important difference \>0.5), exacerbation rate (before and after BT) and hospitalizations (rate and % subjects).

Experience of Biologic Treatments for Severe Asthma: a Survey

Severe asthma is a disease characterised by respiratory and non-respiratory symptoms. The respiratory symptoms can include breathlessness, wheeze and asthma attacks. The disease can come to dominate patients' lives, impacting their social, working and personal lives, leading to depression, anxiety and feelings of social isolation. There are now 7 different biologic treatments available on the NHS in the UK for severe asthma. These treatments have dramatically changed how severe asthma can be treated. Research has typically focused on the benefits of these drugs from a clinical perspective, e.g., improvements in lung function, blood tests and reduction in frequency of asthma attacks and use of steroid tablets. While these are important outcomes, they do not reflect the experiences of patients receiving these treatments, which can vary greatly. First, not all patients benefit to the same degree. Second for patients who do respond, some respond slower than others. Third while these treatments target respiratory symptoms, some patients report wider benefits, such as reductions in fatigue, depression, ability to engage in family life and other daily activities. Fourth, patients report different side effects when starting these treatments and sometimes for months afterwards, including headaches, fatigue, mental fog and joint pain. These experiences are reported by clinicians and patients, but the extent of these four variations is poorly understood, and potential reasons for them have not been explored. To describe these differences between patients' experiences and begin understanding why they are present, we have co-designed a survey with people who have lived experience of severe asthma who are members of the European Lung Foundation's (ELF) Patient Advisory Group (PAG). This process has resulted in a survey that contains content important to patients and is worded in a way that avoids confusion regarding the meaning of the questions.

Potency of HDM Sublingual AIT Tablets in Assuring the Persistency of Asthma Control in HDM Allergic Patients With Severe Asthma, Treated With Tezepelumab

The aim of this drug trial is to evaluate the annualized asthma exacerbation rate under treatment with Acarizax versus placebo. The trial is intended for adults aged 18 to 65 with severe uncontrolled asthma and a house dust mite allergy. The study will involve 32 patients (up to 38 with study dropouts) recruited from French hospitals, in pulmonology and allergology departments. Initially, all participants will receive Tezepelumab for 3 to 6 months (M-3/-6) to control asthma symptoms. If asthma is not controlled after 6 months, the participant will be excluded from the study and will continue on standard treatment. Once their asthma is controlled, patients will be randomized in two groups: * Group A: Tezepelumab + Acarizax® * Group B: Tezepelumab + Placebo After 6 months of treatment with Acarizax or placebo (M6), Tezepelumab will be stopped and participants will continue treatment with Acarizax or placebo alone for a further 12 months (up to M18/End of search). The study will include 5 visits during regular consultations (M-3/M-6, D0, M6, M12 and M18), as well as 2 follow-up telephone calls M3 and M9).

Evaluation of Ventilation Defects Downstream of Mucus Plugs in Patients With Severe Asthma

In this study, xenon MRI will be used to evaluate regional functional consequences of mucus plugs in the lungs of patients with severe asthma.

The main aim is to improve the management of adult severe asthma patients treated with biotherapy, according to their allergic status.

Swiss Severe Asthma Register

Asthma is one of the most common chronic diseases. Asthma is characterized by chronic airway inflammation and associated with airway hyperresponsiveness and reversible airflow obstruction. The variability of airway obstruction is triggered by different factors that lead to a variety of different asthma phenotypes and subtypes. The various classification options for asthma (e.g. severity, by the predominantly existing inflammation or according to triggers), reflect its heterogeneity. Despite improved therapeutic methods, the prevalence and morbidity of asthma has increased worldwide in the last years. Asthma is a serious and growing global health problem with around 300 million people affected, independent of age or sex. Estimated 250'000 people die prematurely each year due to their asthma. Based on the SAPALDIA-study, the prevalence of Asthma in Switzerland is approximately 2-8%. Asthma is considered as a major factor in healthcare cost with up to CHF 1.2 billion per year. Asthma is not only a financial burden to a system; it affects the individual Quality of life negatively. Often health care professionals and patients underestimate the severity of the disease and overestimate asthma control. Severe asthma should not be equated with uncontrolled asthma. To reach a satisfying asthma control numerous factors need to be taken into consideration. Severe asthma is often associated with a high risk of frequent, severe exacerbations, which can even lead to death. Several severe asthma cohorts and registries already exists and are reported in the literature. The aim of such registries is in general data collection and a better understanding of the disease. So far, most epidemiological studies on severe asthma are cross-sectional with no follow up measures. Only a few studies did repeated measures using the same methods. Approximately 5% of all Asthma Patients suffers from severe asthma. These patients require systematic assessment and specialist care in dedicated respiratory centres. These centres have a key role in improving the outcome for severe asthma patients. At the same time they act as gatekeepers to ensure appropriate access to new, expensive therapies, this includes antibody treatment and interventional methods such as thermoplasty. These treatments require careful monitoring. It is important to ensure that they are given to the right population. Special assessment to monitor the efficacy and to prevent inappropriate prescribing, exposure of patients to unnecessary risks and excessive costs is indicated. For all the mentioned reasons a Swiss Severe Asthma Register and a collaboration with an already existing register is needed to prospectively collect data about severe asthma in Switzerland.

Withdrawal of Dupilumab in Severe Asthma

Asthma management has been revolutionised by the development of biological therapies. Dupilumab is an anti-interleukin4 receptor marketed in 2020 for severe asthmatic patients with 2 exacerbations or more within the last 12 months. Although data showed that safety and efficacy of dupilumab are sustained when treatment is extended up to 3 years, no study has emerged regarding dupilumab discontinuation. This study aims to demonstrate the non-inferiority regarding strategy failure at 24 months of stopping dupilumab (intervention group) compared with its continuation (control group) in controlled asthma patients receiving this drug for at least 3 years.

Exploring the Lived Experience of Young Adults With Severe Asthma

Asthma is a serious long-term lung condition caused by swollen airways that narrow. This causes wheezing, chest tightness, and breathlessness. Most asthma is well-controlled with medication. However, 5-10% of asthmatics have severe asthma where treatment does not control symptoms and up to 67% of asthmatics have uncontrolled asthma, caused by not always taking medication as recommended, lifestyle choices or other health problems worsening their asthma. In the UK, asthma affects around 800,000 young adults. This group is at high-risk of having poor asthma control, worse outcomes than other age-groups. This is because young adults need care that differs from other age-groups and current care is not meeting these needs. There is little information on the experiences and needs of this group and very few studies exist, exploring how to improve care. This study will explore the experiences and needs of young adults (age16-25) with severe and uncontrolled asthma. Methods. The investigators will perform two study-arms with young adults with severe/uncontrolled asthma in Manchester and Liverpool severe asthma centres: Study-arm 1: Interview participants using photographs chosen by them to help explain their experiences of living with asthma and support that they need. Study arm 2: Perform group interviews to understand participants' thoughts around the insights from study-arm 1 combined with their own experiences. To explore and develop ideas on how to improve future care. At the end of both study arms, a workshop involving patients and stakeholders involved in delivering care will take place, to identify a joint goal of how to improve care in this cohort and map ways in which to achieve this. Together, the study results and workshop will increase our understanding of the experiences and needs of young adults with asthma. Helping us to identify new ways to improve care which can be tested in future research.

International Severe Asthma Registry: Canadian Cohort

The International Severe Asthma Registry is a global initiative looking to ensure that the care of people with severe asthma will continue to improve by collecting detailed information about the health and treatment of as many people with the disease as possible. The study will gather anonymized longitudinal real-life data for participants with severe asthma for five years. The purpose of the registry is to track the progress of participants and determine how well they are responding to treatment. Medical research using data from the registry will give the investigators a better understanding of severe asthma and help the investigators develop and improve the care and treatment for severe asthma participants. The Canadian cohort of the registry will collect information from Canadian participants with severe asthma across seven different sites.
