Filter by:AZD8848 is a new drug that is being tested for the treatment of asthma and allergic rhinitis (hayfever). This study will be in two parts and will include 59 asthmatic patients in total. The first part will investigate the tolerability and safety of AZD8848 while the second part will investigate both the therapeutic effect of AZD8848 and how well patients tolerate the drug.
The purpose of this study is to determine the efficacy of a multifactorial intervention with weight reduction, behavioural therapy, and physical exercise on the severity and control of asthma in obese children.
This study will evaluate the correct use of sequential formoterol and budesonide inhaler capsule treatment via Aerolizer and patient satisfaction in adult asthmatics.
This Phase 2 study was to investigate the tolerability of unit dose budesonide (MAP0020) at three doses in pediatric volunteers with a diagnosis and history of mild-to-moderate stable asthma and evaluate the pharmacokinetic profile of budesonide resulting from inhalation aerosol delivery.
This is a dose-response study to determine how various measurements of airway inflammation respond to high and low dose FlutiForm®, and compared to placebo.
Asthma is a chronic disease, which means that it cannot be cured, but the investigators can use inhalers and tablets to control the symptoms. In asthma, the airways become inflamed and irritated which can cause coughing and make the airways tighten. This 'inflammation' is the root of the problem in asthma. Doctors have different ways to measure the inflammation in the airways. One way is to measure a gas called nitric oxide (NO) on the breath. This is made by the lungs when asthmatic inflammation is present. The investigators have been using NO as a test in research labs for many years, but there are still unanswered questions about how it changes between morning and night and how quickly medicines work on it. In most asthmatics, even small doses of inhaled steroids (preventers) can reduce the NO levels to normal, but in some people this does not seem to happen. The investigators now have portable NO machines that are designed for patients to use in the home. The investigators want to follow NO readings in patients with high levels to measure how they respond to different doses of steroid inhalers. The investigators hope this will help the investigators better understand asthma inflammation and treatments.
The purpose of this study is to examine whether broccoli sprout extract can effect lung function measurements in individuals with asthma and COPD.
Background: - Individuals who have severe asthma that is not easily controlled by current treatments are in need of new treatments to prevent potentially life-threatening asthma attacks. Experiments in mice have found that a medication called pioglitazone hydrochloride (Actos ), which is used to treat patients with diabetes, may be effective for treating severe asthma. Researchers are interested in determining whether Actos is effective in improving the quality of life in subjects with severe asthma who continue to have symptoms despite maximum standard medical therapy. Objectives: - To assess the effectiveness of pioglitazone hydrochloride as a treatment for patients with severe asthma that is not controlled by standard treatments. Eligibility: - Individuals between 18 and 75 years of age who have been diagnosed with and treated for severe asthma for at least 1 year. Design: - Potential participants will have a screening visit to determine eligibility for the study. The visit will involve breathing tests, chest x rays, heart and lung monitoring, and blood tests. - Eligible participants will have a full medical history and will answer a series of questionnaires about their quality of life with asthma. - Phase 1: Patients will record lung function and asthma symptoms morning and evening for 4 weeks. At the end of this period, patients will be evaluated with breathing, allergy, and blood tests, as well as questionnaires. Patients will also provide a sputum sample. - Phase 2: Patients will receive regular doses of either pioglitazone hydrochloride or a placebo for 16 weeks. Patients will return to the National Institutes of Health every 4 weeks for tests. - Phase 3: Wash-out period without study drugs for 4 weeks, similar to Phase 1. - Phase 4: Patients will receive regular doses of either pioglitazone hydrochloride or a placebo for 16 weeks. Patients who received placebo will be given the study drug, and vice versa. Patients will return to the National Institutes of Health every 4 weeks for tests. - Phase 5: Medications will be stopped, and patients will return to the National Institutes of Health 4 weeks later for final tests.
The primary aims are to test whether an asthma care management system (M-CHESS) delivered via a smartphone (cellular phone with internet access) can support low income teenagers (ages 12-18) with significant asthma and can improve asthma control and reduce asthma-related emergency or urgent care visits and hospitalizations. Secondary aims include whether M-CHESS increases adherence to asthma control medication and reduces absenteeism from school, work or an event they wanted to attend.
The aim of the study is to investigate the effect of inhaled apocynin on ROS (reactive oxygen species) and NOS (reactive nitrogen species) synthesis in 10 nonsmoking mild asthmatics. Effects of nebulized apocynin (0.5 mg/ml, 6 ml) are assessed in exhaled breath condensate (EBC) after 30, 60 and 120 minutes.
