Active clinical trials for "Asthma"

The purpose of this study is to investigate the cytokine levels in nasal lavage and gene expression in nasal scraping following a single nasal dose of JNJ-43260295 in healthy participants, and in atopic mild to mild-persistent asthmatic (breathing disorder in which there is wheezing and difficulty in breathing) participants with and without nasal allergen challenge prior to dosing.

This is a one-year study to look at the safety of a dry powder inhaler with albuterol. After a one-week run in, for the first 3 months subjects will use an inhaler with either albuterol or a dummy drug at regular times four times a day. Then for the last nine months of the study, all subjects will be given the albuterol dry powder inhaler and will use it only when needed to help with breathing problems. Subjects will need to keep a daily diary (both paper and electronic) throughout the study recording any inhaler use and health problems. There will be visits to the study doctor about once a month for a year. This study is intended to show that the albuterol dry powder inhaler works well and is safe for use over a long period of time.

The study includes participants with moderate asthma who were randomly assigned to receive the study medication (CAT-354) or placebo.

The efficacy of inhaled corticosteroids (ICS) in asthmatic subjects showing no sputum eosinophils is controversial. The broad aim of this study is to assess whether ICS alone or in combination with long-acting beta-2 agonists are an effective treatment in non-eosinophilic asthmatic subjects. Methods: The investigators will perform a randomized double-blind, placebo-controlled, multicenter study comparing the efficacy of ICS and placebo for 4 weeks followed by a 4-week open treatment period with ICS/salmeterol in steroid-naïve asthmatic subjects without sputum eosinophilia. The primary outcome will be the the Asthma Control Questionnaire (ACQ) score after four weeks of treatment by ICS or placebo. This study will determine whether or not non-eosinophilic asthmatic subjects respond to ICS and if they further benefit from the addition of a long-acting beta-2 agonists. This study will also determine whether or not the assessment of airway inflammation should be performed in every asthmatic patient in order to give the most appropriate treatment.

To evaluate the effect of MEDI-528 in adults with atopic asthma.

Asthma is a chronic inflammatory disorder of the airways with a variety of inflammatory processes contributing to the pathogenesis. The inflammation leads to a state of increased airway responsiveness and reversible airway obstruction that causes the recurrent symptoms of asthma. Despite the variety of treatments available for asthma, none are curative, and the disease continues to place a burden on society in terms of morbidity, reduced quality of life (QOL), and ever increasing healthcare costs. The prevalence of asthma continues to increase with current data suggesting that since 1980, adult asthma cases have increased by 75% and in children under 5 years of age the prevalence has increased by 160%.1 Additionally, studies have suggested that the disease severity has been underestimated and that more patients may be classified as having moderate to severe persistent disease.2 Inhaled corticosteroids (ICS) have been the cornerstone of anti-inflammatory treatment for decades and have been shown to improve lung function, decrease symptoms, and reduce asthma exacerbations.3 However, many patients are still inadequately controlled despite treatment according to current asthma management guidelines and have a significant unmet medical need. Such patients are at high risk of serious exacerbations and asthma-related mortality.4 Combining long-acting β2-agonists (LABAs) with low dose ICS has been shown to improve asthma control over using higher doses of ICS alone. However, LABAs act mainly at the bottom of the inflammatory cascade and there are concerns that they may mask underlying inflammation.5 Recently, leukotriene receptor antagonists have been added to ICS as second-line therapy in the management of asthma. Zileuton has been extensively studied in inflammatory diseases such as asthma, in which leukotrienes mediate inflammation. The aim of this study is to assess the effect of zileuton controlled-release (CR; 1200 mg 2-times daily [BID]) on pulmonary function, asthma control, and symptomatic response in adult patients with asthma poorly controlled on moderate dose ICS.

This study will be the First Time in Human Study (FTIH) aiming to assess the safety and tolerability of GW805858 for both single and repeat dose. The study also aims to assess safety and tolerability in mild asthmatic subjects as well as healthy volunteers.

To investigate the effects of CAT-354 on airway hyper-responsiveness (AHR) in uncontrolled asthma.

This study involves a FDA approved drug, Omalizumab, used in the treatment of moderate to severe allergic asthma that cannot be controlled by standard treatment. It works on IgE to control the allergic reaction. We are looking at the effects on non-allergic asthma. We hope to prove that Omalizumab will have the same effect on non-allergic asthmatics as it does allergic asthmatics.

The purpose of this pilot study is to establish the feasibility and acceptability of a digital respiratory ecosystem ("Breathe"), that incorporates an acoustic adherence algorithm, asthma/COPD differentiation classification algorithm, a smart inhaler cap, a digital spirometer, and a real-time air quality database to support people living with asthma to better manage their disease and derive personal and clinical value. Through this study, 30 adults will be asked to use Breathe as a way to monitor and manage their asthma symptoms over a 12-week period.
