Active clinical trials for "Asthma"

Workers in the salmon industry are at risk of developing allergies and respiratory diseases, including asthma, due to occupational exposure to bioaerosols, i.e. biological agents such as allergens, enzymes and endotoxins, in their work environment. The overall objective of this intervention trial is to identify effective and feasible control measures (interventions) that reduce exposure to these bioaerosols. The project comprises nine salmon processing factories in northern, central and western Norway. The factories are allocated to either one of the two intervention arms or the control group. In all factories, an assessment of exposure to bioaerosols will be performed. In addition, employees will be invited to undergo a health examination and fill out a self-administered questionnaire including information on demographics, work tasks, health and health promoting factors. The intervention trial is part of a broader study that comprises several substudies including the identification of clinically relevant allergens, investigation of exposure-response relationship between the exposure to individual bioactive agents in bioaerosols and investigations of prevalence of airway symptoms, altered lung function, skin symptoms or immunological responses indicating hypersensitivity. Finally the project includes the identification of health promoting factors that are present in the salmon processing industry. The project is an interdisciplinary multi-center study that places great emphasis on a close dialogue between the researchers and industry in all phases of the project.

This study will evaluate the efficacy, safety of two dose levels of CBP-201 in patients with moderate to severe persistent asthma with Type 2 inflammation.

The Possible Efficacy and Safety of L-carnitine and Biotin as Adjunctive Therapies in Children with Moderate Persistent Asthma

This study will assess the safety, tolerability, pharmacokinetics and preliminary efficacy of 610 as an adjunctive therapy in adult subjects with severe eosinophilic asthma.

The aims of this study are to investigate the effectiveness of an online behavior change (BC) intervention in increasing physical activity (PA) and reducing sedentary behavior in adults with asthma, as well as, in improving other clinical outcomes, in short and medium term. In this single-blind randomized clinical trial, patients with clinically stable moderate to severe asthma, who are physically inactive and do not have cardiovascular and/or osteoneuromuscular impairments will be randomized into control (CG) or intervention (IG) groups (23 in each group). Both groups will carry out a minimum educational program. Additionally, the IG will receive weekly individual and/or group online sessions for 12 weeks of motivation-based BC intervention to promote PA and reduce sedentary behavior, based on both self-determination theory (SDT) and transtheoretical model (TTM). The IG will also receive a pedometer with specific strategies related to it. Both groups will be reassessed immediately after the intervention as well as 6 months after the end of the intervention. The primary outcomes are PA and sedentary behavior, which will be objectively assessed by a triaxial accelerometer (Actigraph wGT3X-BT). Secondary outcomes are: asthma control, functional capacity, quality of life, sleep quality and symptoms of anxiety and depression.

The study's purpose is to evaluate the RI-Asthma Integrated Response (RI-AIR) Asthma Care Implementation Program (ACIP). RI-AIR ACIP uses an electronic information system to screen children with asthma and identify what specific services each child needs based on the child's asthma symptom and health care status. Our main goal is to see if children experience better asthma outcomes as a result of participation in the program. We will provide our intervention to 434 urban, ethnically diverse children, between 2-12 years old with asthma, and their families and evaluate whether participating in the program improves children's asthma outcomes. The second goal is to evaluate how well the program is set up and how we can make improvements to better serve families of children with asthma. The third goal is to gather information and advice from community experts so that we can make the program sustainable. Families that take part in RI-AIR ACIP will participate in the program over the course of a year, including participating in the intervention, and brief follow up visits at 3, 6, 9 and 12 months after completing the intervention. All families will complete the CASE program, which takes place over the course of about 4 weeks and involves in-school or remote school-based asthma education for school aged children, after-school or remote education sessions for their parents, asthma care training for school staff, and an evaluation of asthma triggers in the school. Families of children who have more frequent asthma symptoms and emergency healthcare visits will also compete the HARP program, a home-based program consisting of 3 home sessions (over about 6 weeks) that include individualized asthma education and strategies and supplies for controlling environmental asthma triggers. Both CASE and HARP programs are carried out by certified asthma educators and community health workers. Each child's healthcare provider (HCP) and school nurse teacher (SNT) will receive a standardized, secure email indicating the child is participating in RI-AIR. This email will include a summary of the child's baseline assessment of asthma control and prior health care use, and a description of the program. At the conclusion of the child's participation, the HCP and SNT will receive a summary by secure email summarizing the child's asthma control at the end of the intervention, services delivered, and referrals made, and for HARP participants, triggers observed in the home and supplies and referrals provided.

A Regional, Multicentre, Randomized, Double-Blind, Placebo Controlled, Parallel Group, Phase 3 Study to Evaluate the Efficacy and Safety of Tezepelumab in Adults with Severe Uncontrolled Asthma

The propose of the study is to test the effectiveness of Reach for Control (RFC) as compared to Michigan MATCH to improve asthma symptoms, asthma management and lung functioning and to decrease ED visits and admissions for youth with poorly controlled asthma when integrated into hospital emergency departments and delivered by community health workers. The study is a hybrid implementation-effectiveness design and will test RFC for use in real world, public healthcare settings.

The purpose of this study is to evaluate the effect of a drug called benralizumab in individuals with severe, poorly controlled asthma with eosinophilic airway inflammation. Eosinophils are a type of white blood cell that help fight off infections. Some people with asthma have too many eosinophils in their airways and blood, which can cause airway inflammation. Benralizumab is a new drug that is Health Canada approved and has been shown to rapidly eliminate eosinophils. It has been used in patients with severe asthma to improve lung function and reduce flair-ups, also known as exacerbations. Magnetic Resonance Imaging (MRI) is an imaging tool that can look at the structure of the lungs when a subject inhales a xenon gas mixture. In healthy individuals, the gas fills the lungs evenly, but in individuals with lung disease, some of the areas of the lungs are not filled by the gas and the image looks patchy. These patchy areas are called ventilation defects and they contribute to reduced lung function. The goal of the study is to see if treatment with benralizumab will improve these ventilation defects, overall lung function and blood and sputum eosinophil levels. Subjects will receive treatment with benralizumab a total of 3 times, 4 weeks apart. Before and after treatment, subjects will undergo a series of MRI tests, breathing tests, blood and sputum analysis and a series of questionnaires to evaluate daily quality of life. The hypothesis is that ventilation defects will significantly improve after benralizumab treatment, and that this improvement will be different based on how long the patient has had asthma.
