Filter by:The purpose of this study is to determine the role of versican and hyaluronan measurements in induced sputum as biomarkers of asthma. Enroll 10 subjects with mild persistent asthma who are not receiving treatment with a controller therapy.
A single center pilot study to determine the protective effects of RhuMAB-E25 on airway physiology and biology in allergic asthmatics that undergo bronchoprovocation with methacholine. The primary study objective determines the protective impact of RhuMAB-E25 on airway inflammation as reflected in exhaled nitric oxide (NO) levels in allergic asthmatics. The secondary objective determines the protective effect of rhuMAB E25 against airway bronchoconstriction as reflected in the Provocative Concentration of methacholine to cause a 20% fall in FEV1(PC20) with methacholine challenge testing.
This study will establish a clinical data and serum repository of anaphylaxis cases associated with Xolair administration and control patients who have received Xolair without associated anaphylaxis. This is an observational repository and not an investigational clinical trial. Associated with the repository is an optional skin testing substudy.
This is a multicenter, randomized, double-blind, placebo-controlled study designed to demonstrate the safety and efficacy of MILR1444A compared with placebo in reducing the airway reaction to an inhaled aeroallergen solution in adult patients with mild allergic asthma. The study will randomize approximately 24 patients at five study centers. In the event of patient discontinuation from the study, additional patients may be enrolled at the discretion of the Sponsor.
BDNF has been linked to the pathogenesis of airway hyperresponsiveness in asthma. In this trial, the impact of a treatment with salmeterol and salmeterol / fluticasone on BDNF concentrations will be assessed in patients with asthma. The investigators hypothesize that salmeterol impacts on BDNF concentrations in patients with asthma.
This study aims to investigate the effect of omalizumab on the number of tissue eosinophils and other markers of airway inflammation and remodeling, including thickness of the lamina reticularis, in moderate to severe asthmatics with persistent symptoms and evidence of airway inflammation despite treatment with inhaled corticosteroids and long acting beta-agonists. This study will also investigate the correlation between systemic and pulmonary inflammation, and the correlation between clinical outcomes and changes within the tissue, to assist in the future identification of patients with tissue eosinophilia and their response to treatment, without the need for invasive bronchoscopy.
The purpose of the study is to test the safety, tolerability, immunogenicity and clinical efficacy of the combination treatment AllQbG10 in patients with rhino-conjunctivitis and asthma due to house dust mite allergy in a single-center, open-label setting.
Asthma is a common respiratory disease of unknown etiology which currently affects approximately 7.5 % of the adult population ( ). Asthma is an inflammatory disorder of the airways. Airway inflammation is evident not only in patients with fatal asthma but also in mild asthmatics ( ). Oxidant stress, defined as inadequately controlled generation of toxic reactive oxygen species (ROS) in the cells or tissues is a common feature of inflammation, and has also been documented in asthma ( , ). However, the current understanding of the relationship between the inflammation and the oxidant stress in asthmatic airways is poor. Does oxidant stress contribute to the expression of asthmatic phenotypes independently of inflammation? If so, could asthmatics benefit from supplementation of antioxidants? These questions have been nagging us since our laboratory provided credible evidence of oxidant injury in the airways of allergic asthmatics ( ). The purpose of our study is to more precisely determine 1/ the pathophysiologic role of oxidative stress, and 2/ usefulness of antioxidant therapy using vitamin E in allergic asthma.
This open label single blind study will determine the safety of albuterol sulfate dry powder in a novel inhaler by observing for the potential occurrence of reflex bronchial constriction after inhalation of increasing doses of the compound.
The researchers propose to study the airways of asthmatics given TPI ASM8 for 14 days, and examine the protective effects on allergen-induced bronchoconstriction, hyperresponsiveness and airway inflammation.
