Filter by: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 objectives of this study are to use the Delphi method to assemble an expert panel representing innovation in asthma treatment, to collect freely suggested recommendation statements concerning OCS tapering (and sub-topics) among severe asthma patients from this panel for peer evaluation, and finally to determine the level of consensus for each statement from the panel as a whole.
The goal of this research study is to test how good an app is in making asthma easier to manage for 372 adolescents/young adults. The app is a mobile version of the asthma action plan.
This study will generate patient reported outcomes (PROs) associated with the use of benralizumab as treatment for severe eosinophilic asthma.
To evaluate the safety and efficacy of a bronchial radiofrequency ablation system (SyMap Medical (Suzhou) Ltd) in a population of subjects with severe asthma who are still symptomatic despite being managed on high-dose Inhaled Corticosteroids (ICS) and Long-Acting β2-adrenergic Agonists (LABA).
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.
The investigators have previously confirmed a clinical hunch that women with asthma have difficulties in becoming pregnant. The investigators found increased time to pregnancy (TTP) in women with asthma compared to non-asthmatic women (55 vs 33 months, p<0.001), furthermore, women with asthma had less successful pregnancies following fertility treatment (39.6 vs 60.4%, p=0.002). Treatment with omalizumab stabilizes the eosinophilic disease, through the systemic and most likely the anti-inflammatory pathways, which indicate a promising possibility to increase pregnancy rate. In a small real-life study in 2017, 5 patients with eosinophilic asthma who underwent in vitro fertilization (IVF), were treated with omalizumab prior to embryo transplantation; three out of the five women became pregnant. Lastly, the two remaining patients had several treatments with omalizumab, but did not become pregnant. This real-life study calls for further investigation. By targeting systemic inflammation with omalizumab treatment the aim is to increase asthma control before and during pregnancy. A treatment strategy aiming at improving overall inflammatory control may increase fertility, but also reduce well known maternal and perinatal adverse pregnancy outcomes such as pregnancy loss, preeclampsia, gestational diabetes, low-birth weight, small for gestational age (SGA), preterm delivery. Study design: A randomized control trial with omalizumab and placebo, stratified for blood eosinophil count, is therefore needed. A randomized, double blinded, parallel group, study to evaluate the difference between omalizumab (O) and placebo (P) on pregnancy rate in patients with atopic asthma.Treatment schedule: After collection of material (blood samples, sputum) 6th day (±1 day) of the menstrual cycle, the patients will be randomized in either the omalizumab group or the placebo group. No collection of material will be done at the time of enrollment, as this will be on different time of the female cycles. The treatment is initiated with one injection with weight and serum-immunglobulin E balanced omalizumab or one injection placebo. After omalizumab treatment at ovulation it will again be collected material (blood samples, sputum). If no pregnancy has occurred after first IVF cycle, this will be repeated for 3 consecutive IVF cycles in total or until pregnancy has occurred. Outcome: The primary out-come is efficacy of omalizumab, compared to placebo, in increasing pregnancy rate in females with asthma. Secondary out-comes are changes in the inflammation in lungs/systemic, pregnancy loss, asthma control and biomarkers in the blood/lungs.
Household air pollution (HAP) is a leading risk factor for global burden of disease. Resource-constrained communities of the world especially women and children are significantly impacted by this challenge. To address household air pollution, cleaner and more efficient improved cookstoves (ICS) have been disseminated to low resource communities. Although there has been initial uptake of these stoves, sustained use has been inconsistent adding to the challenge of household air pollution. There is limited understanding at the intersections of social, ecological, and technical determinants of sustained use of ICS, and how is sustained use of ICS associated with exposure and health outcomes in poor communities. The overarching goal of this exploratory study is to initiate a comprehensive research program that will facilitate the use of ICS and investigate whether they render significant health benefits among rural Indian households. The investigators installed ICS (model: Eco-Chulla XXL) in select households that primarily use biomass for cooking, and evaluate the intervention based on three specific aims: 1. To generate preliminary emissions data [particulate matter - mass and surface area based, carbon monoxide (CO)] from ICS and its effect on respiratory health outcomes that will facilitate the development of a pivotal clean cookstove intervention 2. To generate effect size data that establish the feasibility and inform the sample size of a pivotal trial whose primary objective will be sustained improvements in the respiratory health of women and children in rural India 3. To evaluate factors which enable and hinder the sustained use of clean cookstove technologies by the rural poor in India so that the investigators can develop a more refined pivotal intervention focused on improving respiratory health
This randomized study compares operative techniques in chronic rhinosinusitis with polyposis (CRSwNP) surgery. It aims to evaluate outcomes in asthma and CRSwNP, safety and costs. The investigators want to see if patients with certain clinical and/or genetic predispositions will benefit from extended surgery. They also aim to find biomarkers for detection and management models for of severe airway inflammation and to further develop markers for progressive disease forms.
This feasibility study will be open-label with two dose groups: patients receiving budesonide/formoterol Turbuhaler® at a total daily dose [400 to 800 µg[ (group 1) and patients receiving a total daily dose ≥800 µg/day (group 2) to investigate whether there is a relationship between dose and hair concentration. The objective of this feasibility study is to determine if the product administered to the patient is detectable and quantifiable in hair in order to have a mean to monitor adherence to the treatment. This study does not in any way evaluate the efficacy or safety of the medicinal product, which will be used in accordance with its marketing authorization.
