Active clinical trials for "Asthma"

To assess the impact of SQ SLIT-tablets (SQ Grass SLIT-tablet and SQ HDM SLIT-tablet) in Danish and Swedish allergic rhinitis (AR) patients, with or without asthma, between 2007-2020.

The goal of asthma management is to achieve and maintain optimal asthma control. The NEWTON study assesses the evolution over time of patient reported outcomes (PROs) in asthmatic patients, not adequately controlled with ongoing treatments and initiating therapy with extrafine beclometasone dipropionate/formoterol fumarate (BDP/FF) via NEXThaler.

Assess efficacy and safety of omalizumab treatment during 12 months in order to reduce the use of inhaled corticosteroid (ICS) in pediatric and adult participants with severe Immunoglobulin E (IgE)-mediated asthma inadequately controlled with high doses of corticosteroids.

This adaptive design, dose-ranging study of MK-1029 will assess the dose-related efficacy and safety of MK-1029 compared with placebo using measures of lung function (forced expiratory volume in 1 second [FEV1]). The primary objectives are (1) To demonstrate that MK-1029, compared with placebo, results in dose-related improvements in FEV1 over the last 6 weeks of the 12-week active-treatment period; and (2) To determine the dose-related safety and tolerability of MK-1029 as monotherapy and as concomitant dosing with montelukast over 12 weeks. The primary hypothesis is: MK-1029 is superior to placebo in a dose-related fashion in the average change from baseline in FEV1 over the last 6 weeks of the 12-week active-treatment period.

Asthma is a chronic lung disease that affects millions of people worldwide, including both children and adults. The cause of asthma is not known, but asthma is strongly associated with inflammation of the airways, often caused by allergies. In order to control this inflammation, most people with asthma are treated with inhaled medications that contain steroids. These medications do a good job of helping most people with asthma feel better. However, these medications are expensive, have side effects, and do not control symptoms in all people with asthma. Recently basic science research colleagues have shown that inflammation due to allergies can be reduced in experimental animals by a naturally occurring bile acid. Bile acids are chemicals made in the liver that are involved in maintaining healthy digestion of fat. Since bile acids are made by our bodies, they have become popular as over the counter supplements that are thought to be important in promoting a healthy liver and metabolism. Interestingly, other research has shown that bile acids may help patients with neurological disease and diabetes. Given all of this information, the investigators propose that a specific bile acid called tauroursodeoxycholic acid (TUDCA) may be helpful in patients with asthma. Before studying this in a clinical trial, the current study is designed to demonstrate that people with asthma can take TUDCA safely and that it doesn't hurt their asthma. The study will involve inviting 12 patients with mild asthma to take TUDCA daily for 12 weeks. During this time the investigators will closely monitor them for any side effects and check their blood and breathing capacity for any signs of detrimental effects. In addition, the investigators will collect cells that line the nose, which are thought to be similar to cells in the airways of the lungs, to see if TUDCA is having any beneficial effects on inflammation. In order to ensure the use of high quality TUDCA, which may or may not be true of over the counter supplements, the investigators have asked the company that is supplying TUDCA for the studies mentioned previously involving neurological disease and diabetes to supply the drug; the brand name is Taurolite. In addition, even though TUDCA is available over the counter, in order to use it for research, the FDA has to approve this use. Accordingly, the investigators have applied for and received permission (IND) from the FDA to use Taurolite for this study.

This study evaluates the longterm clinical outcomes, including safety and efficacy parameters after Bronchial Thermoplasty (BT) treatment over a period of 5 years. All patients included in de TASMA trial in the Netherlands will be asked to participate in the TASMA extension study.

This study was a 2-treatment period, randomized, multicenter parallel-group study. The overall purpose of this study was to provide long- term safety data for fevipiprant (QAW039) (Dose 1 and Dose 2), compared with placebo, when added to the Global Initiative for Asthma (GINA) steps 3, 4, and 5 standard-of-care (SoC) asthma therapy (GINA 2016), in patients with moderate-to- severe asthma. The purpose of this study was to provide long-term safety data for QAW039 150 mg once daily and 450 mg once daily, compared with placebo, when added to GINA steps 3, 4, and 5 standard-of-care asthma therapy (GINA 2020) in adult and adolescent (≥12 years) patients with moderate-to-severe asthma. The study included 2 cohorts of patients: Rollover patients who had completed any of the four Phase 3 pivotal efficacy studies with QAW039 (QAW039A2307, QAW039A2314, QAW039A2316, or QAW039A2317, hereafter referred to as Studies A2307, A2314, A2316, and A2317), thus providing data for a longer duration of exposure, and New patients who had not previously participated in a study of QAW039, permitting an increase in the number of patients with long-term exposure to QAW039. By including these 2 categories of patients, the total number of patients treated with QAW039 as well as the duration of exposure to QAW039 treatment was substantially increased, supporting evaluation of the safety profile of QAW039.

The purpose of this study is to establish the influence of the non-steroidal candidate-drug pemirolast on allergen-induced airway obstruction and inflammation in allergic subjects with asthma. Pemirolast is an orally available inhibitor of the release of mast cell mediators. The study will therefore test the hypothesis that global inhibition of the mast cell, resulting in decreased production of most of its mediator molecules, will provide a highly significant anti-asthmatic effect.

Asthma is one of the most common chronic diseases affecting children in the UK. Poorly controlled asthma manifests with chronic cough, wheeze and shortness of breath which in-turn has a significant negative impact on a child's quality of life, interfering with sleep, impairing exercise ability and resulting in frequent school absences and hospital admissions. Management of paediatric asthma in the UK is directed by the British Thoracic Society (BTS) Guidelines, which recommend a stepwise (one to five) treatment plan. Step three of the management guideline for children aged 5-12 years of age recommends the addition of the preventer inhaled medication, including long-acting β2 agonists such as salmeterol. However, there is a wide variation in response to this medication with approximately one in seven people, with a specific genetic change, found to have an increase in asthma symptoms in association with the use of thisiss medication. A related medicine, formoterol, is used less commonly in children with asthma. In this study, the investigators will aim to identify children with asthma whose symptoms are poorly controlled on inhaled long-acting beta2 agonists. Via a simple saliva test, the investigators will identify the presence or absence of the specific genetic change potentally influencing the effectiveness of treatment with salmeterol or related longacting beta2 agonists thus enabling the investigators to recommend either salmeterol or an alternative medication for the treatment plan such as montelukast. The investigators will randomise the patients into two groups; to receive "personalised care" where the choice of controller medication would be based on the child's gene test results and predicted response to long-acting beta2 agonists, or "standard care" following the BTS guidelines at the clinician's discretion without knowledge of the gene test results. The investigators aim to measure whether this individualized approach to asthma prescribing results in improved control of asthma symptoms and overall quality of life. Targeting treatment to a child's specific genetic make-up is a concept known as "personalised medicine".

This is an exploratory study with the following primary objectives: 1) to establish that PET/CT of the lung can reliably distinguish healthy, non-asthmatic participants from participants with severe asthma and an eosinophilic phenotype and 2) to examine the utility of PET/CT for demonstrating that reslizumab produces a reduction in lung inflammation in participants with severe asthma and an eosinophilic phenotype .
