Activation and Function of Eosinophils in Conditions With Blood or Tissue Eosinophilia

Subjects admitted on this protocol will have elevated eosinophil counts in the peripheral blood or tissues or will be relatives of subjects with eosinophilia. Eosinophilic subjects will undergo an extensive clinical evaluation focused on the identification of the cause of eosinophilia and the presence of end organ manifestations. In addition, ...

Phase N/A

Role of Genetic Factors in the Development of Lung Disease

This study is designed to evaluate genetic mechanisms of lung disease by surveying polymorphic genes involved in respiratory function and examining gene expression in the lung cells of individuals with pulmonary disease (e.g., alpha 1-antitrypsin deficiency, asthma, chronic obstructive pulmonary disease, cystic fibrosis, sarcoidosis, history of infection, and genetic mutations ...

Phase N/A

Segmental Bronchoalveolar Lavage

This protocol proposes to perform bronchoalveolar lavage, bronchial brushing and bronchial wall biopsy in research volunteers and in patients with pulmonary disease to evaluate the cellular components of normal and diseased lungs. This research study will help to improve our understanding of pathogenic mechanisms in the lung during progression of ...

Phase N/A

Sample Collections From the Airways of Asthmatic Patients

This tissue procurement protocol proposes to perform bronchoscopy with bronchoalveolar lavage, bronchial brushings, and bronchial wall biopsies as well as to collect samples of sputum, exhaled breath condensates and blood, in order to evaluate the molecular mechanisms underlying the pathogenesis of airway inflammation, airway hyperresponsiveness, and airway remodeling in asthmatic ...

Phase N/A

Longitudinal Observational Study of Severe Asthma

Asthma is a common disease and a significant public health problem, affecting one in every 10 individuals, nearly 30 million people in the US alone. About 5-10% of asthmatics have severe disease that is difficult to control with standard therapies. Severe asthmatics are considered to be relatively resistant to corticosteroids, ...

Phase N/A

Analysis of Inflammation and Microbiome in Patients With Sinusitis and Asthma

This is a cross-sectional and non-interventional study to investigate mechanisms of disease in patients with asthma who have concomitant chronic sinusitis and/or nasal polyps (upper airway disease). Approximately 160 participants will be enrolled. Patients who are scheduled to undergo inpatient or outpatient endoscopic sinus surgery at the University of California ...

Phase N/A

Comparative Study of Pathophysiological Mechanisms and Bronchial Response in Occupational Asthma to Wheat Flour and Quaternary Ammonium Compounds During Standardized Bronchial Provocation Tests

Occupational asthma (OA) caused by high molecular weight (HMW) substances have been shown to induce predominantly an eosinophilic inflammation. In contrast, OA caused by low molecular weight (LMW) substances results in a neutrophilic inflammation. In addition, data regarding phenotype of lymphocytes in OA caused by HMW and LMW substances are ...

Phase N/A

A Multicenter Randomized 52 Week Treatment Double-blind Triple Dummy Parallel Group Study to Assess the Efficacy and Safety of QMF149 Compared to Mometasone Furoate in Patients With Asthma

The purpose of the trial is to evaluate the efficacy and safety of two different doses of QMF149 (QMF149 150/160 g and QMF149 150/320 g via Concept1) over two respective MF doses (MF 400 g and MF 800 g via Twisthaler (total daily dose)) in poorly controlled asthmatic patients as ...

Phase

Cessation Versus Continuation of Long-term Mepolizumab in Severe Eosinophilic Asthma Patients

Primary objective of the study is to evaluate whether patients with severe eosinophilic asthma who have received long-term treatment with mepolizumab (at least 3 years) need to maintain treatment with mepolizumab to continue to receive benefit. Subjects who participated in the open-label studies MEA115666 or 201312 with at least 6 ...

Phase

Study of Efficacy and Safety of QAW039 in Patients With Severe Asthma Inadequately Controlled With Standard of Care Asthma Treatment.

A double-blind, placebo-controlled study to evaluate the efficacy and safety of two doses (Dose 1 and Dose 2) of QAW039 compared with placebo over a 52-week treatment period in in each of the groups (patients with severe asthma and high eosinophil counts and all patients with severe asthma). Efficacy will ...
