Filter by:The purpose of this study is to determine the safety of an anti-asthma herbal medicine intervention (ASHMI) in adult asthmatics and to see what effects ASHMI has on certain parts of the immune system.
This study is designed to determine if the investigational drug is effective and safe in individuals with asthma
The primary objective of this study is to explore the efficacy of Nasonex (mometasone furoate nasal spray) in comparison with placebo in improving the quality of life of subjects with moderate to severe persistent allergic rhinitis and intermittent asthma. A secondary objective is to evaluate the efficacy of Nasonex in relieving the subject's symptoms of allergic rhinitis and asthma.
This study will evaluate the safety and efficacy of QAX576 against asthma attacks in adults with moderate persistent allergic asthma
The goals of control status of asthma have been changed with the improvement of its management as a chronic disease; many steps should be taken to achieve asthma control as defined by the GINA/NIH guidelines. There are good results with single variables, but overall asthma control should be addressed in different ways. Most traditional clinical studies provide an incomplete assessment of disease control, despite good clinical practice. The association of inhaled corticosteroid (IC) and long-action beta 2 agonist (LABA) has already showed their efficacy to reduce asthma symptoms, exacerbations and cost for moderate and severe asthma patients as well as the improvement in their quality of life. On the other hand, even with the use of first line maintenance medication, as recommended by guidelines, some asthmatic patients fail in obtaining a total control of the disease. This lack of efficacy, led us to hypothesize, that these patients who fail in response, would present chronic and fixed airway obstruction as a consequence of persistent inflammation and airway remodeling. This study has the purpose of looking for an adequate composite measure to provide an indicator of overall asthma status more accurately and meaningfully as reflect of treatment effectiveness and disease control. For this, we will test by a randomized control trial if an additional oral corticosteroid treatment could modify spirometric and plethysmography values, nasal and low airway cytology and HRCT (to evaluate small airway) in regularly treated stable asthma patients who have a positive bronchodilator response.
The purpose of this study is to investigate how mucus (phlegm or spit) is broken down once it forms in the airways (bronchial tubes) of people with lung disease. This research study will also examine whether blood groups have an effect on lung function or the type of mucus found in the lung. This study is not designed to be a treatment for asthma, emphysema, cystic fibrosis, or other lung disease. It is designed to help the investigators learn more about the causes of airway disease.
Asthma is a heterogeneous disorder in which multiple potential inflammatory pathways contribute to airway obstruction. The biological basis for airway inflammation is the subject of intensive investigation. This work is designed to identify airway factors that are responsible for recruiting cells and associate their airway presence with atopy and asthma.
The purpose of the study is to find out how well a long-acting beta agonist like salmeterol works in people with different forms of the same gene. Our hypothesis is that asthmatics with the Arg/Arg genotype will have loss of bronchoprotection against exercise-induced asthma with regular salmeterol treatment, as compared to asthmatics with the Gly/Gly genotype.
The purpose of this study is to identify the causes of asthma that were not previously suspected, to better understand the effects of inhaled steroids on asthma and to identify new way to treat asthma. In order to take advantage of the most current scientific expertise, we (scientists at UCSF) plan to work together with Genentech Inc. We believe that working with Genentech will provide the best chance of developing new treatments for asthma.
Chronic obstructive pulmonary disease (COPD) and asthma are common respiratory diseases in which people experience long-term inflammation of the lungs. Exacerbations, or prolonged worsening of symptoms, of asthma and COPD are often life-threatening and can lead to frequent need for hospitalization. Even with the proper use of bronchodilators, corticosteroids, and other currently available medications, clinical responses among people with COPD and asthma are variable. There remains a significant unmet clinical need for new therapeutic approaches and insights, including the identification of biomarkers to accurately assess the presence of airway infection and intensity of airway inflammation. This study will investigate potential natural biological causes and new biomarkers for increased susceptibility to persistent airway infection in asthma and COPD.
